Description
Technical field
What the present invention relates to is a kind of environment protection type sheet material and manufacture method thereof of producing for having furniture made to order.
Background technology
Have furniture made to order and can break the limitation in space, there is the matching degree with main body height, fully can improve space availability ratio, save living space, and fully can meet the Individualized Pursuit of different consumer to style of furniture, become the popular mode of buying furniture of society.
Production base material used of having furniture made to order at present adopts solid wood granule plate (particieboard) and medium density fibre board (MDF) usually, these materials have lightweight, strength ratio is high, good springiness, shock-resistant, texture rich palette is attractive in appearance and the advantage such as handling ease, but major part is with the synthetic resin of liquid state containing aldehyde in solid wood granule plate and medium density fibre board (MDF) production process, if Lauxite, melmac etc. are as adhesive, its product, at the formaldehyde manufactured and all can discharge in use procedure, can produce harm greatly to human body and environment.Meanwhile, also there is water resistance and the problem such as dimensional stability is undesirable in solid wood granule plate and medium density fibre board (MDF), seriously limits the development of having furniture made to order in the application.
Although veneer and covering with paint can alleviate the problems referred to above effectively, having furniture made to order in process, Drilling operation is necessary operation, and this can cause sealing effect to weaken, and inevitably discharges free formaldehyde.In addition, in furniture use procedure, coming off of edge sealing is also a common defect, and it not only affects attractive in appearance, and increases the chance that the release of free formaldehyde and hydrone enter widely.Therefore, the adhesive of use high-performance, environmental type is the measure of essence.
Substitute conventional based Wood Adhesives with the thermoplastic resin of film-form and prepare wood-based plate, production technology is simple, and equipment investment is few, production efficiency is high, can solve the problem of free formaldehyde release from root.If publication number is the Chinese invention patent of CN102181239A, propose a kind of method utilizing formaldehydeless film adhesive to make glued board and laminated material in the same way, obtain the glued board that has the advantages such as high water proofing property, elongation at break and notch impact strength concurrently and laminated material in the same way.Simultaneously, publication number is that the Chinese invention patents such as CN104308915A " a kind of formaldehyde-free plywood production technology ", CN103144152A " a kind of formaldehyde-free plywood and preparation method thereof ", CN104139445A " gluing together the manufacture method of indoor glued board or floor base material without aldehyde " and CN103934877A " a kind of particleboard with zero-formaldehyde emission and manufacture method thereof " have all done exploration in Thermoplastic synthetic's plate, but said method has certain limitation in the selection of wood material, as the thermoplastic resin of film-form only for Monoplacophora wood material compound.And when gluing together with wood particle or wood fibre, usually select the thermoplastic resin of particle or powder type, not only increase compounding process, and easily occur the phenomenon that raw material mixing is uneven, gluing is insufficient.
Meanwhile, the wood material of nonpolar thermoplastic film and polarity is thermodynamically inconsistent, and this greatly constrains it in the application of more areas.Although utilize various method to carry out pretreatment to wood material, can improve the performance of sheet material, owing to there is complex process, the problem such as cost is high, energy consumption is high, chemical agent pollution is difficult to realize large-scale production.
Summary of the invention
What the present invention proposed is a kind of environment protection type sheet material and manufacture method thereof of producing for having furniture made to order, its object is to the above-mentioned defect overcome existing for prior art, have formaldehydeless release, manufacturing process is simple and easy to control, and product water resistance is good, intensity high.
Technical solution of the present invention: a kind of for the environment protection type sheet material produced of having furniture made to order, its structure comprises at least three layers of wood fibre or wood particle, be arranged at the tack coat that the thermoplastic film material through plasma modification process between every layer of wood particle or wood fibre upper and lower surface is formed, one or both in described particieboard or fiberboard.
Its preparation method, comprises the steps:
1) wood fibre or wood particle are dried to moisture content 0 ~ 15%, then determine the consumption of every layer of wood particle or wood fibre and the number of plies of thermoplastic film according to the thickness of target plate;
2) thermoplastic film is cut into the size identical with target plate breadth, and carry out plasma treatment;
3) by wood fibre dried in step 1) or wood particle, spreading is on the thermoplastic film material of described plasma treatment equably in gradation, and wherein last one deck wood particle or wood fibre upper surface lay the thermoplastic film of one deck plasma treatment;
4) material paved in step 3) is sent in hot press, under hot pressing technique, carry out hot pressing, make the abundant melting of the thermoplastic film of plasma treatment between every layer of wood fibre or wood particle, sprawl and infiltrate in the cellular structure of wood fibre or wood particle;
5) sheet material after hot pressing in step 4) is proceeded in cold press carry out later stage heat treatment.
The invention has the advantages that:
(1) can produce not containing the environment-friendly wood particle board of formaldehyde and fiberboard, this is most outstanding feature; (2) sheet material prepared has higher bonding strength, anti-bending strength and good water resistance, owing to have employed plasma, pretreatment has been carried out to thermoplastic film simultaneously, increase the surface-active of thermoplastic film, improve the interface binding power between thermoplastic film and wood fibre or wood particle, substantially increase the mechanical property of sheet material.
