Background
The structure of the solid wood composite floor mainly comprises a surface layer, a solid wood layer and a bottom layer from top to bottom, wherein the solid wood layer is generally formed by staggered lamination of boards of different tree species, the surface layer is mainly responsible for decoration and wear resistance, and the bottom layer is mainly responsible for moisture resistance and deformation resistance.
On the other hand, the existing solid wood composite floor is mostly made by adopting a resin impregnation mode on the surface layer so as to ensure that decorative paper and wear-resistant paper can be simply and quickly bonded and fixed, but the problem still exists is that the moisture-proof paper on the bottom layer is additionally coated with bonding resin, which is very troublesome and inefficient.
Therefore, in summary, there is an urgent need in the market for a structure-improved solid wood composite floor with sufficient surface wear resistance, high overall connection strength, and convenient and efficient production
The patent publication No. CN212376199U, chinese patent publication No. 2021.01.19 discloses a novel sound-proof heat-insulating bamboo-wood floor, which comprises the following structures: taking aluminum oxide wear-resistant impregnated paper as a wear-resistant layer; polyvinyl chloride resin film is used as a heat insulation layer; taking the recombined wood sheet as an upper surface plate; taking a high-density bamboo fiber board as a core plate; taking the recombined bamboo sheet as a lower bottom plate; taking a sound insulation felt as a sound insulation layer; the aluminum foil moisture-proof pad is used as a moisture-proof layer.
However, the bamboo-wood floor of the utility model still needs to be additionally coated with adhesive among the lower base plate, the sound insulation layer and the moisture-proof layer, so that the production efficiency of the whole bamboo-wood floor is reduced.
Disclosure of Invention
The invention provides a solid wood composite floor with a high wear-resistant resin impregnated paper facing and a production method thereof, which can achieve the aims of effectively producing the improved solid wood composite floor and achieving outstanding comprehensive performance of the solid wood composite floor by arranging a wear-resistant decorative layer and a balance moisture-proof layer on the upper side and the lower side of a solid wood substrate respectively, arranging reinforced fibers in the wear-resistant decorative layer, mutually stripping the wear-resistant decorative layer and the balance moisture-proof layer to share impregnated resin.

Detailed Description
The following description is of the preferred embodiments of the invention and is not intended to limit the scope of the invention.
Examples: as shown in fig. 1,2, 3, 4,5 and fig. 6, a solid wood composite floor with a high abrasion-resistant resin impregnated paper facing comprises a solid wood substrate 3, an abrasion-resistant decorative layer 1 provided on the upper surface of the solid wood substrate 3, and a balance moisture-proof layer 2 provided on the lower surface of the solid wood substrate 3.
In this embodiment, the solid wood substrate 3 is made by selecting oak and Canadian pine according to the prior art, and the wear-resistant decorative layer 1 and the balance moisture-proof layer 2 are impregnated with resin on both sides of the wear-resistant decorative layer 1, then the balance moisture-proof layer 2 is peeled off after the resin is adhered, so that a proper amount of required resin can be left on the balance moisture-proof layer 2, which has the advantages that: firstly, the whole production process is simple, and the balance moisture-proof layer 2 is not additionally coated with resin; the second and the second positions have the same resin components and different dosages, so that the structural and performance uniformity of each layer of the wood composite floor can be further ensured; third, how much resin needs to be left on the balance moisture barrier 2 is flexible and adjustable.
The wear-resistant decorative layer 1 sequentially comprises wear-resistant paper 101, a composite bonding layer 102, decorative paper 103 and a first bonding layer 104 from top to bottom. Reinforcing fibers 102a which are used for increasing the transverse tensile capacity of the wear-resistant decorative layer 1 in a transverse arrangement mode are arranged in the composite bonding layer 102. The reinforcing fibers 102a are suspended by the center weight 102b to maintain the U-shaped transverse arrangement.
In this embodiment, the composite adhesive layer 102 and the first adhesive layer 104 are both formed by impregnating resin, but the initial thickness selection of the two layers can be achieved by adjusting the impregnation entrance angle of the decorative paper 103, which is very flexible, wherein the thickness of the composite adhesive layer 102 is set to be 1.5-2.1mm, and the thickness of the first adhesive layer 104 is set to be 1.2-1.6mm, so that the sufficient accommodating space of the reinforcing fiber 102a is ensured.
In addition, the abrasion-resistant decorative layer 1 is mainly subjected to compression deformation after being compressed, and if the composite adhesive layer 102 is formed by single resin, the transverse tensile capability of the composite adhesive layer 102 is far insufficient, and the composite adhesive layer 102 has the problems of collapse and fracture after being used for 1-2 years, so that the reinforcing fibers 102a are required to be introduced to strengthen the transverse tensile capability of the composite adhesive layer 102, and the composite adhesive layer 102 is prevented from being crushed relatively easily.
The reinforcing fibers 102a are made of organic polypropylene fibers or nylon fibers, and inorganic glass fibers or carbon fibers, so that the stress can be transferred inside the composite bonding layer 102, and the problem that the composite bonding layer 102 is easily partially collapsed due to the locally concentrated stress is avoided, and the length of the reinforcing fibers 102a is 3.0-5.0cm.
Finally, the middle counterweight 102b and the reinforcing fiber 102a are integrally formed, which is essentially only a middle expansion block, so as to ensure that the reinforcing fiber 102a can be in a U-shaped form and transversely positioned in the composite bonding layer 102, thereby avoiding the reinforcing fiber 102a from being too vertical, otherwise, the transverse tensile capacity improving effect is greatly compromised.
The balanced moisture barrier 2 comprises a second adhesive layer 201 and composite kraft paper 202 from top to bottom. The composite kraft paper 202 includes a kraft paper body 202a, a mesh cloth 202b provided on an upper surface of the kraft paper body 202a for attaching a bonding resin, and bonding strips 202c provided at both side positions on the upper surface of the kraft paper body 202a, respectively, for pre-bonding the mesh cloth 202 b.
In this embodiment, the balanced moisture barrier 2 needs to be partially impregnated with resin "robbed" from the decor paper 103, so that if an existing, single kraft paper is used for the balanced moisture barrier 2, the amount of resin remaining thereon is limited and cannot be used at all to firmly bond the solid wood substrate 3.
Thus, the scrim 202b is previously fixed to the kraft paper body 202a by the adhesive strips 202c on both sides, so that a relatively large amount of impregnating resin is trapped on the scrim 202b, ultimately ensuring that the second adhesive layer 201 has a sufficient and proper thickness.
The materials of the composite adhesive layer 102, the first adhesive layer 104, the second adhesive layer 201 and the adhesive strip 202c are all the same resin.
In this embodiment, the impregnating resin is any one of an amino resin, an epoxy resin, or a phenolic resin.
The wear-resistant paper 101 and the composite kraft paper 202 are each provided with a protective film 14 on one of the sides before the solid wood composite floor is prepared.
In this embodiment, the protective film 14 is a conventional transparent plastic film, and functions in two ways: first, the wear-resistant paper 101 and the composite kraft paper 202 are protected during the initial storage and transportation process; second, the protective film 14 is wound around the driving roller when the abrasion-resistant decorative layer 1 and the balance moisture-proof layer 2 are pressed and peeled off, so as to be used as a power source for advancing the abrasion-resistant decorative layer 1 and the balance moisture-proof layer 2.
The production method of the solid wood composite floor with the high wear-resistant resin impregnated paper facing comprises the following steps in sequence:
S1, impregnating resin on two sides of the decorative paper 103 to obtain a decorative layer precursor 11;
s2, spraying the reinforcing fibers 102a on one side of the decorative layer precursor 11 to obtain a decorative layer substrate 12;
s3, respectively pressing the wear-resistant paper 101 and the composite kraft paper 202 on two sides of the decorative layer substrate 12, and tearing off the protective film 14 to obtain a composite layer 13;
And S4, peeling the composite kraft paper 202 from the composite layer 13 to obtain the final wear-resistant decorative layer 1 and the balance moisture-proof layer 2 respectively.
S3, pressing the wear-resistant paper 101 and the composite kraft paper 202 at the same time; in S4, a stainless steel knife with the thickness of 0.03-0.2mm is adopted to conduct stripping operation on the composite layer 13, an acute included angle a between the wear-resistant decorative layer 1 and the composite layer 13 is 15-22 degrees, and an acute included angle b between the balance moisture-proof layer 2 and the composite layer 13 is 45-48 degrees.
In this embodiment, the decorative paper 103 is impregnated with resin by winding the impregnated roll, and the reinforcing fibers 102a are blown by an open-pore box plus a blower, so that the decorative layer precursor 11 can be blown off and added as needed.
In addition, the pressing pressure of the abrasion-resistant paper 101 and the composite kraft paper 202 is 50-400N/cm, and finally the thickness of the second adhesive layer 201 obtained by peeling the abrasion-resistant paper 101 and the composite kraft paper 202 is 1.4-1.8mm, so that the composite kraft paper 202 can be firmly adhered to the solid wood substrate 3, and then the mesh cloth 202b is also in the area of 1.4-1.8 mm.
Finally, the wear-resistant decorative layer 1 and the balance moisture-proof layer 2 are respectively drawn and discharged at different angles, so that the 'holding quantity' of the impregnating resin on each of the wear-resistant decorative layer and the balance moisture-proof layer can be adjusted, and of course, the impregnating resin at the composite bonding layer 102 is not carried away by the balance moisture-proof layer 2.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present invention. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
