Abstract
The present invention relates to a mineral-bonded wood strand cement (magnesite, gypsum) board consisting of a mixture of wood strands or other similar fibrous material, water, a suitable binder such as cement, magnesite or gypsum, and possibly additives, which mixture is baked under pressure to form a board with a practically completely closed surface. For the board according to the invention, the wood strands used are wider but thinner than the wood strands used hitherto in (acoustical) wood wool cement (magnesite, gypsum) boards. The invention also relates to a method for manufacturing such a wood strand cement (magnesite, gypsum) board.
Description
The present invention relates to the bonding wood strand cement (magnesite of a kind of mineral, gypsum) plate, this plate by wood strand or other like fibrous material (for example, wood wool, film, smear metal, thin slice etc.), form such as the suitable adhesive of cement, magnesite or gypsum one class and mixture that may additive, under pressure, cure this mixture to form the virtually completely closed plate in a kind of surface.
Wood cement board and fiber cement board worldwide are used in a large amount of different application.For other plate, the advantage of these plates be durability and opposing fire, moist, rot, mould and termite.
Wood cement board is known have been passed through an about century.These plates are made by wood wool and cement, magnesite or gypsum, and this wood wool is preferably the crimped fibre of restricted width.These known plates have opening matrix (open matrix) and therefore density is less.At first, these plates be used to insulate purpose and as the substrate of whitewashing ceiling.Now, these plates also are used for decorative purpose and are used as abatvoix.By introducing the automaton of making these plates, can realize these application.Along with the development of the machine of control system, mixture is evenly distributed in the mould (mould), piles up and push this mould and the constant plate of workmanship becomes feasible with new blend with control raw-material exact dose and mixing.Because high-quality template can be low-costly made in the existence of these machines.Especially, wood mold coupled by using (concrete blinding) and low pressure machine, the cost of the apparatus for production line of wood cement board is lower.
But because their open matrix structure, wood cement board is not suitable for the structure of picture outer wall cover plate and shingle one class, and for this outer wall cover plate and shingle, importantly closure and waterproof are wanted in the surface.In addition, for this application, the intensity of wood cement board is not enough.
Now in other plate, fiber cement corrugated sheet or dull and stereotyped or take repeatedly the application that shide is used for picture outer wall cover plate and shingle one class.These plates and goods have closed matrix and waterproof.Optionally, can have burr in the dull and stereotyped surface, for example, slate, fragment of brick or the imitative grain of wood.As of late, these fiber cement boards are mainly made by cement and asbestos fiber, so because the durability of these materials, intensity and low-cost being suitable for.In many countries, asbestos fiber is replaced by cellulose and artificial fiber now, mainly is owing to ban use of the legislation of asbestos, because asbestos are for the manufacturer of plate with to add industry and commerce be dangerous.But the shortcoming of fiber cement board is that so firm and durable and artificial fiber and hard cellulose are expensive again unlike sheet asbestos for these plates.
HOII P 10010195 has been described a kind of wood cement board, and this plate has wooden and advantage fiber cement board, these advantages relate to durability and opposing fire, moist, rot, mould and termite.
But these plates have a large amount of essential disadvantages.
One of shortcoming is in the compression upper strata of being made by cement mortar or other encapsulant, occurs hair crack on the surface, does not especially pass through coating processing for example in the situation of japanning at cement layer.Another shortcoming is because the density of these plates is lower, and its density is 800 to 900kg/m
3, flexural strength also falls far short, and in addition, the ability of the screw beaten of these plates property tack hole and hold-down screw and nail also has problem.
Other problem appears in the manufacture process of these plates, as die mould, apply the edge of joint tongue and groove and this plate of cutting sth. askew.In addition, under the effect that water content changes since not with same surface balance, these plates can be crooked.
Described the present invention aims to provide a kind of wood strand cement (magnesite, the gypsum) plate that can eliminate above-mentioned shortcoming.
For this purpose, the invention provides a kind of like this wood strand cement (magnesite, gypsum) plate, this plate is by a kind of wood strand or like fibrous material, water, make such as the suitable adhesive of cement, magnesite or gypsum one class and mixture that may additive, under pressure, cure this mixture to form the virtually completely closed plate in a kind of surface, it is characterized in that this wood strand is wider than but is narrower than so far and still is being used for the wood wool that the wood wool cement of sound-absorbing purpose (magnesite, gypsum) plate uses.
Surprisingly show, adopt this ratio to be used in the wideer and thinner wood strand of wood wool in the sound-absorbing wood cement board so far and, can eliminate above-mentioned shortcoming quite effectively by saving the compression upper strata of forming by cement mortar or other encapsulant.
For obtaining better result, advantageously, the wood strand width is 1-12mm or bigger, preferred 3-10mm, with and thickness be 0.15-1.0mm, preferred 0.15-0.3mm.
Show that surprisingly adopt the wood strand with sharp edges, the edge of this wood strand just no longer appears.In addition, it shows and no matter when arbitrarily distributes wood strand, just can obtain a kind of smoothly and almost do not have the surface of swelling after pressurization, and does not need to adopt the sawdust described in HOII P 1010195 and the covering layer of cement.
Owing to have 900 to 1200kg/m according to plate of the present invention
3Between, preferred 1000-1100kg/m
3Between density, therefore with aforementioned HOII P in the density described be 800 to 900kg/m
3Known plate compare, plate of the present invention has higher flexural strength.
In addition, according to plate of the present invention tack hole and play screw better, and screw, staple and nail are fixed in this new material better.
Described this high-density plate has caused the very big improvement handled about plate, for example die mould, apply the edge of joint tongue and groove and this plate of cutting sth. askew.
It should be noted,, need not whitewash in order to obtain special smooth surface although can brush or whitewash this plate.Verified, do not need to do further surfacing and for example brush, this plate just can waterproof.
Surprisingly show, adopt that will to cause flexural strength to be that cementing flakeboard for density low about 20% sets the twice of standard according to long wood strand of the present invention many, also make the manufacturing of this plate quite cheap in addition.
According to providing for example burr of fragment of brick, slate or the grain of wood on the one side of plate of the present invention, this makes them be suitable for durable overlay or the backing plate of doing on the building outside.
Another significant advantage of described plate be their opposing fire, moist, rot, mould and freezing and frost.In addition, they also resist the destructive effects of various weather conditions and termite.
Quite durable and can successfully be used in and be subjected to tropic countries that hurricane, storm and earthquake torment for example Central America (Honduras, Guatemala, Salvador, Nicaragua) according to plate of the present invention.
In addition, the present invention relates to make the operating process of wood strand cement plate, it is characterized in that following steps:
A) a kind of mixture by wood strand, water and cement, magnesite or gypsum is assigned in the mould;
B) accumulation has raw-material mould to the expection height;
C) give stacking pressurization, to obtain expection plate density with raw-material mould; And
D) keep this height by the so-called bottom that utilizes the connecting rod connection to be positioned under the stacking in the initially stage of curing of this cement, magnesite or gypsum with the top that is positioned on this stacking.
Adopting width is that 1-12mm or bigger, preferred 3-10mm and thickness are the wood strand of 0.15-1.0mm, preferred 0.15-0.3mm.
Particularly advantageous is that the angle that provides on wood strand, especially this wood strand with sharp edges less than 120 ° is provided.
In addition, for making this plate, can adopt as the two veneer moulds of counterpressure with the steel overlay.
For making according to wood strand cement (magnesite, the gypsum) plate with convex surface of the present invention, a separate board is placed on the top of mould self and it has the opposition profile.
For certain convex surface, advantageously on opposition convex plate, distribute subsequently will be pressurized with the mixture of the wood strand, water and the cement that obtain required convex surface, and additionally employing may not be mixed with for example sealant of cement, magnesite or the gypsum of sawdust of short fiber.
In a kind of preferred implementation according to operating process of the present invention, applying and distributing in the process of wood strand, water and cement, magnesite or gypsum, with long laterally the comparing of plate, to the small part wood strand more towards this plate long vertically.Because this of wood strand be orientated longitudinally with respect to plate, thereby improved the variation of water content, then this plate in the vertical intensity and the Linear Stability of elasticity and this direction will increase.
Be manufactured with in the situation of adequate thickness at this plate, they can be sawn into wood lath or sheet or slab.I type beam and other profile can be assembled by strip, lath or the slab that the present invention obtains.These strips, slab and beam especially have the country of many wooden buildings, for example the U.S., Scandinavia, Canada etc. because their intensity, stability and their are resisted fire and termite and are applicable to very much construction work.These slabs also are advantageously used for the durable outer cladding plate of building.
