Abstract
The present invention is composite artificial board and its making process, and belongs to the field of composite artificial board making technology. The composite artificial board is made with stalks, wood material and shavings as material, and organic adhesive, and through mixing, spreading, pressurizing and other steps. The composite artificial board has stalk material in the core layer and wood material in the surface layers, and is superior to pure stalk board. The composite artificial board of the present invention has the advantages of low cost, high performance and environment friendship, and may be used widely in building decoration, reinforced floor and furniture.
Description
Technical field
The present invention relates to composite artificial board and manufacture method thereof.
Background technology
All will produce a large amount of stalks every year in agricultural production.Crop straw burning is that the peasant handles one of main method of stalk.Crop straw burning is not only wasted resource, goes back contaminated environment simultaneously, influences the traffic safety of the normal flight and the highway of air station flight, and great disaster hidden-trouble also lies dormant.For solving the handling problem of stalk, one of present main way is to utilize stalk to make wood-based plate (referring to Chinese invention patent application number 03135176.X disclosed " stalk middle and higher density wood-based plate and manufacturing technique method and purposes "), but has following problem on present artificial board of straw and the manufacturing technology thereof:
1, the distortion of stalk plate is big, and is difficult to overcome.
2, must use isocyanates as binding agent, the sticking easily heating platen of wood-based plate when hot-forming (industry slang cry haftplatte-down with) just must the use remover for overcoming the haftplatte phenomenon, has increased cost.
3, in order to overcome the haftplatte phenomenon, must spray remover respectively, but it penetrates into the surface bonding strength decline that can cause plate in the material of top layer in the upper and lower surface of the base of mating formation.
4, the urea-formaldehyde glue price that isocyanate glue is more commonly used than wood fibre board, wooden flake board is high more than 10 times, causes cost too high.
The existence of above problem has seriously restricted the development of artificial board of straw industry.
In addition, existing wood fibre board, wooden flake board have advantages such as the deep processing performance is good, physicochemical property is good, but also exist formaldehyde and other harmful substance to influence human body and environment, and problem such as timber resources is limited.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, provide that a kind of cost of manufacture is low, good physical and chemical properties, the feature of environmental protection be good, broad-spectrum composite artificial board and manufacture method thereof.
Solution of the present invention is to make core material with thin attitude stalk product, makes skin-material with thin attitude timber product, adds binding agent, through mat formation, operations such as precompressed, moulding, cutting, timeliness, sanding make composite artificial board.Stalk fibre or the stalk wood shavings of described thin attitude stalk product for making through universal method, described thin attitude timber product makes the wood fibre that is mixed with aldehyde adhesive or wood particle etc. with timber such as forest zone three surplus things or small firewood materials through universal method.
Described binding agent is two kinds, and what promptly the stalk sandwich layer was used is isocyanate glue, and what wooden upper and lower top layer was used is aldehyde adhesive.
The composite artificial board that so makes, because of its upper and lower top layer is wooden, the advantage that has kept wood materials, these class agricultural wastes of stalk have been utilized simultaneously, comply with the development and the environmental protection requirement of recycling economy, and overcome the shortcoming of pure artificial board of straw, have the intensity height, moistureproof, anti-deformation performance and processability are good, good physical and chemical properties, advantage such as environmental protection more; Because top layer isocyanate-free glue, no haftplatte phenomenon does not need remover, because of the top layer is wooden, uses common aldehyde adhesive, reduced the consumption of isocyanate glue relatively, thereby cost is lower.Can be widely used as the material of building, decoration, furniture manufacturing.
Description of drawings
Below in conjunction with accompanying drawing content of the present invention is further specified.
Fig. 1 is the structural representation of composite artificial board of the present invention
Fig. 2 is the vertical view of Fig. 1
Fig. 3 is the flow chart of the method for preparation composite artificial board of the present invention
Referring to Fig. 1～2, this composite artificial board is made upper epidermis 1 and following top layer 2, thin attitude stalk product by thin attitude timber product and is bondd by sandwich layer 3 pressings and constituted.Stalk fibre or the stalk wood shavings of described thin attitude stalk product for making through universal method, described thin attitude timber product makes the wood fibre that is mixed with aldehyde adhesive or wood particle etc. with timber such as forest zone three surplus things or small firewood materials through universal method.
Referring to Fig. 3, the preparation method of this composite artificial board may further comprise the steps:
Method embodiment 1:
(1), timber such as the surplus things in forest zone three, small firewood material are obtained wood fibre through general technology, admix the top layer under constituting on the press of mating formation behind urea-formaldehyde glue or other aldehyde adhesive;
(2), stalk after making stalk fibre and admix isocyanate glue, common processes is mated formation on following top layer the formation sandwich layer;
(3), the wood fibre that will be mixed with urea-formaldehyde glue is mated formation on the sandwich layer of step 2 formation top layer 1;
(4), promptly make this composite artificial board through precompressed-hot-forming-cutting-cooling-stacking-Ageing Treatment-sanding then.
The composite artificial board that so makes, after testing, product quality meets GB/T1178-1999 " medium density fibre board (MDF) ", LY/T1611-2003 " floor base material fiberboard ", GB18580-2001 " formaldehyde discharges and limits the quantity of in interior decoration, finishing material wood-based plate and the goods thereof " standard-required.
Wood fibre in the example can replace with wood particle, stalk fibre can replace with the stalk wood shavings, the composite artificial board that makes, and product quality also can meet above-mentioned standard-required.
Method embodiment 2:
(1), get wood fibre board and be layered on the press and constitute top layer down,
(2), the thin attitude stalk product that will be mixed with isocyanate glue is layered in the wood fibre board that serves as down the top layer, constitutes sandwich layer,
(3), get on the sandwich layer that wood fibre board is layered on step (2), constitute upper epidermis,
(4), promptly make this composite artificial board through precompressed-hot-forming-cutting-cooling-stacking-Ageing Treatment-sanding then.
Method embodiment 3:
(1), get wood fibre board and be layered on the press and constitute top layer down,
