Background technology
Timber is made it have through high-temperature process the characteristic such as anticorrosion, protection against the tide, fungi-proofing (worm) and forms carbonized wood.Carbonized wood not easily absorbs moisture, is not easy to deformation, is a kind of wood materials being commonly used at present.Additionally, carbonization technology is it is also possible that plywood, (or be called clamping plate, the wood plank relatively thin by cladding coincides) obtains modified upgrading (carbon stable material), and then promotes board quality.It is currently known and mainly has following several plywood carbonization operating type:
First kind of way: take cladding wood single-plate, each layer polyethylene bond paper is that glued medium gives gluing；Then group embryo supporting plate (aluminium sheet or other backing plate) is sent into the hot press pressing and forming of 210 DEG C of high temperature above.But, above-mentioned operating type has a problem in that: polyethylene bond paper is expensive, than generally commercially available WBPPlywood (waterproof pluwood, generally with 100° centigrade steaming and decocting) or MRPlywood (moistureproof plywood, generally with 60 degree of steaming and decoctings Celsius) required for the adhesive expensive several times of material cost；Higher production cost, makes volume of production limited.Additionally, general splicing or the wood single-plate through repairing not easily operate, enter hot press very bothersome, it is easy at random, operation difficulty, it is impossible to first pre-molding, and whole wood single-plate entirely must be adopted, also can improve production cost further.
The second way: after the leading carbonization of each veneer in cladding timber, then bond with the adhesive material needed for WBPPlywood or MRPlywood clamping plate.But, owing to each veneer is the thin slice of 0.3～6mm, easily catch fire very much with continuous dryer carbonization, and because the energy is wasted greatly in carbonization time length, dehydrator space, cause that effect and efficiency are less good.Additionally, each veneer is easily damaged and must repair in carbonisation, in turn result in operation puzzlement.
The third mode: plywood is made directly high temperature hot pressing carbonization.But, this kind of method problematically, common gel composite, then through more than 215 DEG C high temperature cabonizations, often make structure be difficult to bear long-time high temperature and damage of coming unglued.
Summary of the invention
In view of the problems referred to above of the prior art, inventors believe that there is a kind of ameliorative way, for this preparation method designing kind of carbonization plywood, step at least includes:
1. taking plural number wood single-plate, the average thickness of each wood single-plate is not less than 0.15mm；
2. drying, the moisture content of each wood single-plate is below 8%；
3. mutually carry out glued and combined lining up use specification with the one in silicone based glue, phenolic resin glue, urea-formaldehyde resin glue, heatproof epoxy glue, polyimides glue, melamine modified glue water, high temperature resistant inorganic nanocomposite binders by two-layer wood single-plate adjacent one another are；
4. plate embryo is colded pressing decompression after 30 points～45 points, send hot press, carbonization of shaping；
5. hot pressing temperature is at 210 DEG C～250 DEG C, and hot pressing time is that 30-60 divides；
6. plate embryo cooling.
By the present invention, two-layer wood single-plate adjacent one another are was coated glue with the one in silicone based glue, phenolic resin glue, urea-formaldehyde resin glue, heatproof epoxy glue, polyimides glue, melamine modified glue water, high temperature resistant inorganic nanocomposite binders mutually, and become to use specification through entire row, less costly but still suitable tack strength can be maintained.Silicone based glue, phenolic resin glue, urea-formaldehyde resin glue, heatproof epoxy glue, polyimides glue, melamine modified glue water and high temperature resistant inorganic nanocomposite binders that the present invention adopts have heat-resisting quantity, the globality of its structure can be kept when high temperature and stick together stability and not easily degumming deformation, being therefore quite suitably applied high-temperature field and cohere.Therefore, plate embryo can be colded pressing 30 points～45 points by the present invention after sticking together, and send hot press after decompression, makes heat and pressure be synchronously performed.The hot press high temperature cabonization of the present invention shortens work flow, simplifies operating type, reduces cost, and the shortcoming that can solve current all known plywoods.Further, plywood product produced according to the present invention, it is possible to improve the value of building materials, decoration, furniture and relevant processing, and benefit producers and consumers with easy method.
