For example, Japanese Patent Application Laid-Open No. 2000-190309 discloses a wood-based cosmetic material in which a makeup sheet having a thin surface layer of natural wood is adhered on a substrate including a wood board, and a reinforcing sheet is adhered to the other surface. In the present invention, a wood cosmetic material for flooring is disclosed, wherein the reinforcing sheet is difficult to permeate the wood resin liquid exuded from the wood board.

However, conventional flooring cosmetics have insufficient scratch resistance (impact resistance and castor resistance), and concave portions easily occur due to local loads, which tends to damage uniform smoothness.

In addition, the construction of the bottom surface is performed by joining a plurality of flooring materials for the flooring material (rabbet formed on the side) by fitting the unevenness, but if the moisture invades the connecting portion, the deformation of the wooden board Or it may cause corrosion.

(1) a first step of forming a synthetic resin layer having a thickness of 100 µm or more on a plane portion of a wooden board;

(2) a second step of forming at least one of silver and small holes by silver-coating the side surface of the wood board;

(3) a third step of laminating the makeup sheet on the synthetic resin layer, and

(4) 4th process of folding the edge part of the said makeup sheet so that not only the whole synthetic resin layer but some or all of the said silver and a small hole may be covered.

Hereinafter, each process is demonstrated using drawing.

First step

In a 1st process, the synthetic resin layer of 100 micrometers or more in thickness is formed in the planar part (the diagonal line area shown by 3 of FIG. 2) of a wooden board.

The synthetic resin layer in this invention is what is called a backer layer (layer for alleviating the surface unevenness | corrugation of a wooden board), and is distinguished from the makeup sheet mentioned later.

As the wood board used in the present invention, for example, sliced veneer, wood veneer, wood plywood, particles made from various materials such as cedar, cypress, oak, pine, nawang, teak, merapi, etc. Boards, MDF, and the like. Although the thickness of a wooden board is not specifically limited, About 3-15 mm is preferable and about 6-12 mm is more preferable.

Although the synthetic resin layer should just be 100 micrometers or more in thickness, 200 micrometers or more are preferable and 250 micrometers or more are more preferable. As an upper limit, it is about 800 micrometers, and 500 micrometers or less are preferable. By laminating such a synthetic resin layer, since the influence of the unevenness of the wooden board can be alleviated, a good flatness can be provided on the surface of the flooring decorative material. In addition, by the lamination of the synthetic resin layer, the design (non-sense and three-dimensional feeling) can also be imparted to the flooring decorative material.

The synthetic resin layer may be a single layer or a multilayer. As physical properties, it is preferable that the influence of the unevenness of the wood board can be alleviated. Specifically, it is preferable that the yield point load is 9 kgf or more, the tensile elasticity modulus is 50 kgf / mm 2 or more, and the yield elongation is 3 to 8%.

As the synthetic resin, for example, polyethylene terephthalate (preferably biaxially stretched polyethylene terephthalate), polyalkylene terephthalate having high heat resistance (for example, 1,4-cyclohexanedimethanol and the like) Polyethylene terephthalate substituted by: Brand name: PET-G (made by Eastman Chemical Company), polybutylene terephthalate, polycarbonate, polyarylate, etc. are mentioned. Synthetic resin may be single or a mixture.

As shown in 10 of FIG. 3, the synthetic resin layer may be previously chamfered. In this case, since the bending at the time of further laminating the makeup sheet in the third step can be made smooth, the adhesion of the makeup sheet can be further improved.

The formation method of a synthetic resin layer is not specifically limited, For example, the method of laminating | stacking a synthetic resin sheet on a wood material using an adhesive agent is mentioned. When not using an adhesive agent, a synthetic resin layer can also be laminated | stacked by extrusion lamination (lamination by melt extrusion).

Second Step

In a 2nd process, one or more types of silver and a small hole are formed by silver-joining the side surface of a wooden board. Silver joint processing is performed according to a well-known method.

The silver formed by silver-joint processing is what is called a "protrusion", and it means the convex part formed in the side surface of a wooden board. On the other hand, the small hole formed by the silver joint processing is a so-called "groove" and refers to a recess formed on the side of the wood board. These silver and small holes are used to connect a plurality of wooden boards. That is, wood boards are connected by fitting the convex part (silver lead) and the recessed part (small hole) of a wood board.

2 shows a wood board in which both the silver 1 and the small hole 2 are formed on the side. In the aspect of FIG. 2, although the cross-sectional shape of a silver and a small hole becomes a prismatic uneven | corrugated shape, it may be any shape, such as semi-circular uneven | corrugated shape and triangular prism uneven | corrugated shape. In addition, although both silver and a small hole are formed in FIG. 2, only one of a silver or a small hole may be formed in the side surface of a wooden board.

This is because the necessity of silver and a small hole changes according to which position of the flooring material (flooring space) is arrange | positioned.

Third step

In a 3rd process, a makeup sheet is laminated | stacked on the said synthetic resin layer.

An example (top view) of the lamination method of the makeup sheet is shown in FIG. 1. As shown in 1) of FIG. 1, the makeup sheet is based on the premise of using a larger one than the flat part of the wood board. The sheet shape (planar shape) can be set suitably according to the shape of the planar part of a wooden board. For example, when the shape of the planar portion of the wood material is square or rectangular, the shape of the makeup sheet is preferably a similar form. Thereby, not only a flat part but also the side surface of a wooden board can be efficiently covered. In this case, as shown in 2) of FIG. 1, it is preferable to cut off the four corners of the makeup sheet. Thereby, it becomes easy to fold a cosmetic sheet. In addition, as a makeup sheet in 1) of FIG. 1, the cosmetic sheet from which the four corners were cut | disconnected from the beginning can also be used.

A cosmetic sheet can be laminated | stacked on a wood material with an adhesive agent, for example. Although it is not limited as an adhesive agent, a urethane type adhesive agent is preferable.

The cosmetic sheet may be a known or commercially available cosmetic sheet. For example, the makeup sheet which laminated | stacked the design layer (solid ink layer and pattern ink layer), the transparency resin layer, and the transparency surface protection layer in order on the base material sheet is preferable. In addition, the solid ink layer means a layer in which all of the ink is planarly painted. Although the thickness of a makeup sheet is not limited, About 80-200 micrometers is preferable.

Such a makeup sheet is demonstrated below.

The base sheet is a woven fabric containing paper, wood fiber, glass fiber, asbestos, polyester fiber, vinylon fiber, rayon fiber, or the like, such as paper, high-quality paper, kraft paper, Japanese paper, titanium paper, resin impregnated paper, paper reinforced paper, or the like. 1 type, or 2 or more types of laminated bodies, such as synthetic resin sheets, such as a nonwoven fabric, polyolefin, polyester, polyacryl, polyamide, polyurethane, and polystyrene, are mentioned. As thickness of a base material sheet, about 20-300 micrometers is suitable.

The base sheet may be colored by a pigment or the like, and may further be subjected to corona discharge treatment, plasma treatment, ozone treatment, or the like. Moreover, when a urethane type primer layer is formed in order to improve adhesiveness with a synthetic resin layer on the other surface of a base material sheet, adhesiveness of a makeup sheet and a synthetic resin layer becomes further high.

The design layer is composed of a patterned ink layer and / or a solid ink layer. The pattern layer is usually formed by gravure printing, offset printing, silk screen printing or the like. In the figure, for example, wood grain, stone grain, cloth texture, leather pattern, geometric pattern, letters, symbols, line drawing, various abstract pattern, and the like. The solid ink layer is formed by solid printing with a concealed coloring ink capable of concealing the coloring of the substrate sheet or the like on the substrate sheet. The pattern layer may be composed of both a patterned ink layer and a solid ink layer, or may be composed of only one.

The ink used for forming a design layer is not limited. For example, what mix | blended and inkized binder resin, a pigment, a solvent, various auxiliary agents, etc. can be used. Examples of the binder resin include chlorinated polyolefins such as chlorinated polyethylene and chlorinated polypropylene, polyesters, polyurethanes containing isocyanates and polyols, polyacryl, polyvinyl acetate, polyvinyl chloride, vinyl chloride-vinyl acetate copolymers, and cellulose resins. And polyamide resins. Among these, in consideration of environmental problems, adhesion to the printed surface, and the like, it is preferable to mix one or two or more kinds of polyurethanes, polyacryl, polyamide-based resins such as polyesters, isocyanates and polyols, and the like. .

A transparency resin layer will not be specifically limited if it is a transparent resin layer, For example, it can form preferably with a transparent thermoplastic resin.

As the transparent thermoplastic resin, soft, semi-rigid or hard polyvinyl chloride, polyethylene terephthalate, polybutylene terephthalate, polyamide, polyethylene, polypropylene, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, Ethylene-acrylic acid ester copolymer, ionomer, acrylic acid ester, methacrylic acid ester, etc. are mentioned. Among the above, polyolefin resin, such as polypropylene, is preferable.

The transparency resin layer may be transparently colored by addition of a coloring agent. As a coloring agent, the pigment used by a design layer can be used.

The transparent resin layer may contain a filler, a matting agent, a foaming agent, a flame retardant, a lubricant, an antistatic agent, an antioxidant, an ultraviolet absorber, a light stabilizer, a radical scavenger, and a soft component (for example, rubber).

The transparent surface protective layer provides the makeup sheet with scratch resistance, abrasion resistance, water resistance, stain resistance and the like. As resin which forms a transparency surface protection layer, curable resin, such as thermosetting resin and ionizing radiation curable resin, is preferable. Especially ionizing radiation progress resin is preferable from a viewpoint of high surface hardness, productivity, etc.

Examples of the thermosetting resin include unsaturated polyester resins, polyurethane resins (including two-component curable polyurethanes), epoxy resins, amino alkyd resins, phenol resins, urea resins, diallyl phthalate resins, melamine resins, and guar. Namin resins, melamine-urea co-condensation resins, silicon resins, polysiloxane resins, and the like.

Hardening agents, such as a crosslinking agent and a polymerization initiator, and a polymerization accelerator can be added to thermosetting resin. As the curing agent, isocyanates and organic sulfonates can be added to unsaturated polyester resins and polyurethane resins, organic amines can be added to epoxy resins, and radicals such as peroxides such as methyl ethyl ketone peroxide and azoisobutyl nitrile. An initiator can be added to the unsaturated polyester resin.

As a method of forming a surface protective layer by thermosetting resin, the method of apply | coating a solution of thermosetting resin by the coating method, such as a roll coating method and the gravure coating method, for example, and drying and hardening is mentioned. As application amount of a solution, about 5-30 micrometers is preferable as solid content, and about 15-25 micrometers is more preferable.

The ionizing radiation curable resin is not limited as long as it causes a crosslinking polymerization reaction by irradiation with ionizing radiation and changes to a three-dimensional polymer structure. Ionizing radiation means having an energy quantum capable of polymerizing and crosslinking a molecule among electromagnetic waves and charged particle beams. For example, visible light, ultraviolet rays (near ultraviolet rays, vacuum ultraviolet rays, etc.), X-rays, electron rays, ion rays, and the like. Although there are, it is preferable to use ultraviolet rays, electron beams and the like.

As an ultraviolet source, light sources, such as an ultrahigh pressure mercury lamp, a high pressure mercury lamp, a low pressure mercury lamp, a carbon arc lamp, a black light fluorescent lamp, and a metal halogen lamp, can be used. As the wavelength of the ultraviolet ray, a wavelength region of about 190 to 380 nm can be used. As an electron beam source, various electron beam accelerators, such as a coke croft Wald type | mold, a vandraft type | mold, a resonance transformer type | mold, an insulation core transformer type | mold, a linear type | mold dynatron type | mold, and a high frequency type | mold, can be used, for example. As an intensity | strength of an electron beam, generally about 100-1000 keV, Preferably about 100-300 keV can be used. The irradiation amount of the electron beam may be generally about 2 to 15 Mrad.

The ionizing radiation curable resin includes monomers, prepolymers or polymers having a radical polymerizable unsaturated group such as a (meth) acryloyl group, a (meth) acryloyloxy group, or a cationic polymerizable functional group such as an epoxy group in a molecule thereof (hereinafter, Collectively referred to as compound). These monomers, prepolymers and polymers may be used alone or in combination of two or more. In addition, in this specification, a (meth) acrylate is used by the meaning of an acrylate or a methacrylate.

As the prepolymer having a radical polymerizable unsaturated group, polyester (meth) acrylate, urethane (meth) acrylate, epoxy (meth) acrylate, melamine (meth) acrylate, triazine (meth) acrylate, polyvinyl Pyrrolidone etc. are mentioned. As for this prepolymer, the thing of molecular weight about 10000 or less is used normally. When the molecular weight exceeds 10000, surface properties such as scratch resistance, abrasion resistance, chemical resistance and heat resistance of the cured resin layer are insufficient. Although the above-mentioned acrylate and methacrylate can be used in common, acrylate is fast in terms of the crosslinking curing rate in ionizing radiation, and thus acrylate is advantageous in order to cure efficiently at high speed and in a short time.

Examples of the prepolymer having a cationically polymerizable functional group include epoxy resins such as bisphenol epoxy resins, novolac epoxy resins and alicyclic epoxy resins, aliphatic vinyl ethers, aromatic vinyl ethers, urethane vinyl ethers, and ester vinyl ethers. Prepolymers, such as vinyl ether resin, a cyclic ether compound, and a spiro compound, are mentioned.

As a monomer which has a cationically polymerizable functional group, the monomer of the prepolymer which has the said cationically polymerizable functional group can be used.

The ionizing radiation curable resin sufficiently cures when irradiated with an electron beam, but in the case of curing by irradiating with ultraviolet rays, a photopolymerization initiator is added as a sensitizer. As a photoinitiator applied to resin containing a radically polymerizable unsaturated group, acetophenones, benzophenones, thioxanthones, benzoin, benzoin methyl ether, mihirabenzoyl benzoate, mihiraketone, diphenyl One or more kinds, such as sulfide, dibenzyl disulfide, diethyloxide, triphenylbiimidazole, and isopropyl-N, N-dimethylaminobenzoate, can be used. In addition, when applied to resin containing a cationically polymerizable functional group, 1 or more types, such as an aromatic diazonium salt, an aromatic sulfonium salt, a metallocene compound, a benzoin sulfonic acid ester, a furyloxy sulfoxium diallyl iodide salt, can be used. Can be.

Although the addition amount of a photoinitiator is not specifically limited, Generally, it is about 0.1-10 weight part with respect to 100 weight part of ionizing radiation curable resins.

As a method of forming a protective layer from an ionizing radiation curable resin, the solution of an ionizing radiation curable resin can be apply | coated by application | coating methods, such as the gravure coating method and the roll coating method, for example. As application amount of a solution, about 5-30 micrometers is preferable as solid content, and about 15-25 micrometers is more preferable.

In the case of further providing scratch resistance, abrasion resistance and the like to the surface protective layer formed from the ionizing radiation curable resin, an inorganic filler can be blended into the surface protective layer. As the inorganic filler, for example, powdered aluminum oxide, silicon carbide, silicon dioxide, calcium titanate, barium titanate, magnesium pyroborate, zinc oxide, silicon nitride, zirconium oxide, chromium oxide, iron oxide, boron nitride, diamond, gold steel, glass Fiber, and the like.

As addition amount of an inorganic filler, it is about 1-80 weight part with respect to 100 weight part of ionizing radiation curable resins.

As a formation method of a cosmetics sheet, for example, after a pattern layer is formed by printing with respect to a base material sheet, a transparency resin layer is laminated | stacked on a pattern layer by dry lamination or T-die extrusion method. When lamination | stacking by dry lamination, it is preferable to use the adhesive for dry laminations containing a two-component curable urethane resin. Subsequently, a cosmetic sheet is obtained by forming a transparent surface protection layer on a transparency resin layer, and performing an embossing process as needed. The concave-convex shapes provided by embossing include conduit grooves, slab surface concave-convex, cloth surface textures, checkered patterns, sand grains, hairlines, and bare grooves.

Fourth step

In a 4th process, the edge part of the said makeup sheet is folded so that not only the whole synthetic resin layer but some or all of the said silver and a small hole may be covered. In addition, the order of folding the edge part of a makeup sheet is not specifically limited. For example, in the case of a rectangular shape as shown in Fig. 1, the makeup sheet can be folded in the long direction as shown in 3) of FIG. 1, and then the makeup sheet can be folded in the short direction as shown in 4) of FIG. . In the present invention, the folded cosmetic sheet is adhered to the wooden board with an adhesive if necessary. As an adhesive agent, the adhesive agent which obtains favorable adhesiveness with a wood material other than the said urethane type adhesive agent can be used.

The aspect which folds up a makeup sheet is not specifically limited as long as it covers a part or all of silver and a small hole. For example, as shown in FIG. 3, it is preferable that the makeup sheet was folded so as to surround the silver-processed side surface. More preferably, it is folded so that a wooden board may not be exposed, when it connects with the other cosmetic material for flooring which was processed by silver-coated process. This can be suitably adjusted according to the state of silver processing, etc. For example, in the case of a protrusion (convex), it is a side surface of a wooden board like A-C of FIG. 4, and can be folded so that it may cover at least the surface from an upper surface edge part to a silver area. In the case of the groove portion (concave), it is a side surface of the wood board, as shown in D to E of FIG. 4, and can be folded so as to cover the surface from at least the upper end to the small hole region.

Regarding silver, the upper end is a portion (side) indicated by the thick line 4 in FIG. 5. The concealed region is an oblique region (region 7 is a region following 6 and another surface region of 5) indicated by 5, 6 and 7 in FIG. That is, in the decorative material for floor coverings of this invention, a makeup sheet is necessarily laminated | stacked on the vertical surface between the edge | side shown by the thick line 4 of FIG. 5, and the area | region shown by 5 of FIG.

Regarding the small hole, the upper surface end portion is a portion (side) indicated by the thick line 8 in FIG. 5. The small hole area is an area (not shown) having a side indicated by the thick line 9 in FIG. 5, and is a region in which the silver area of the protrusion contacts when fitting a plurality of floor covering materials. That is, in the decorative material for floor coverings of this invention, a makeup sheet is necessarily laminated | stacked on the vertical surface extended from the side shown by the thick line 8 of FIG. The lamination | stacking aspect of the makeup sheet which satisfy | fills these conditions has the aspect (a thick line represents a makeup sheet) shown, for example in FIG.

The lamination | stacking aspect of a makeup sheet is demonstrated more concretely as follows. Namely, 1) the upper surface of the synthetic resin layer, 2) the side surface of the wood board and at least the surface extending from the upper surface end to the silver area, and 3) the side surface of the wood board and the surface from the upper surface end to the small hole region. Are stacked.

6 shows an example after laminating a makeup sheet. In the aspect shown in FIG. 6, folding of a makeup sheet is an example by A of FIG. 4.

Step 5

In this invention, the process of forming a curved surface at least in a synthetic resin layer can be included by embossing from the makeup sheet of the material obtained by the 4th process as a 5th process as needed. After forming a curved surface, the part containing the curved surface is cut | disconnected so that it may become a material edge part, and the decorative material for flooring material whose curved surface part was obtained is obtained. By connecting such a floor covering cosmetic material, the bottom surface with favorable design can be formed.

2. Flooring Cosmetic

In the decorative material for floor coverings of this invention, the synthetic resin layer of 100 micrometers or more in thickness is laminated | stacked on the upper surface of the said wooden board. The synthetic resin layer provides uniform smoothness, good scratch resistance and the like to the flooring decorative material. Furthermore, by laminating the synthetic resin layer, the flooring decorative material also has good designability (solidness and three-dimensional feeling).

The decorative material for floor coverings of this invention is laminated | stacked the makeup sheet on the surface shown by said 1) -3), and its hygroscopicity is high. In particular, since the makeup sheet is laminated on the surfaces 2) and 3), both water resistance and moisture absorption resistance are good. Specifically, when a plurality of floor covering materials are connected, moisture and moisture are prevented from entering into the floor covering materials in the connecting portion. This is advantageous from the viewpoint of preventing deformation and alteration of the flooring decorative material.
