Description
Technical field
The present invention relates to a kind of bamboo plywood and manufacturing approach thereof, relate in particular to a kind of bamboo clappers of recombinate bamboo clappers and bamboo chip glued board gummed, belong to bamboo development and bamboo clappers processing technique field.
Background technology
The bamboo clappers that exists in the market is main with simple bamboo chip glued board, and this kind bamboo clappers can directly be used for can be used as the material that furniture is made behind indoor and outdoor floor, the lagging.The product that also has is with this bamboo chip glued board and veneering.Like the patent No. is that 200620104966.0 Chinese utility model patent discloses a kind of bamboo chip veneer composite board; It comprises upper layer, intermediate layer, the following bottom of one deck at least; Each contiguous concatenation sewer has binding agent; The splicing seams of each adjacent layer is separated by 90 °, and described upper layer is that the rectangular flat assembly of bamboo chip slabbing is made up or flat stacked put combination or intersection establishment combination with following bottom, and said intermediate layer is that cylindrical strip plant is formed set; The cylindrical strip plant in described intermediate layer is that the tiling combination is integrated.Because the levels of this utility model is by being that bamboo wood is processed, so the good fineness of case hardness is good; But the bulk strength of this utility model is not high, and because the density of material is not high, therefore is not suitable for doing top-grade furniture.And for example the patent No. is that 200920105908.3 Chinese utility model patent discloses the bamboo-wood composite board that the ultra thick rotary cut venner of a kind of usefulness is made, and it comprises central layer, panel and backboard, and said central layer is the ultra thick rotary-cut plate of 4.5mm～12mm; Said panel and backboard are to be processed by bamboo wood, and said central layer comprises that adjacent layer is the said ultra thick veneer of several layers that rift grain combines, and between adjacent said veneer, glue-line is set, and the binding agent of said glue-line is the aquosity polymer isocyanic ester adhesive; The ultra thick veneer of described sandwich layer is the veneer after overstress enzyme degradation treatment, promptly is formed with the crackle of point-like or wire in the rift grain direction of the loose side of every layer of said veneer.This utility model and the above-mentioned patent No. are that 200620104966.0 Chinese utility model is similar on overall structure, have similar pluses and minuses, various mechanical properties performances still can, but still do not reach the requirement of making high-quality furniture.
In addition, also have on the market mao bamboon rolled the well-thought-out plan silk after, carry out the sheet material that impregnation hot repressing forms again.Like application number is that 200820102820.6 Chinese invention patent discloses a kind of reorganization bamboo; The reorganization bamboo assembly forming method of this invention; Comprise that with little mao bamboon and various dwarf bamboo be primary raw material, form the cellular construction of bar pencil after treatment, successively with dry after the cellular construction applying glue of bar pencil; Become to set the slab of thickness, under certain pressure and temperature, keep a period of time then through mechanical continuous action extruding assembly again, form shaping slab with certain tack.And for example the patent No. is the method that 99117809.2 Chinese invention patent discloses a kind of recombining bamboo material into reinforced shapes, puts it briefly, and is to take the broken well-thought-out plan silk of mao bamboon, and impregnation is adorned mould after dry, in that (10～100MPa) press cured become section bar through high pressure.This method utilization rate of bamboo is high, and technology is simple, and the section bar of processing has the density height, and intensity is high, the advantage that dimensional stability is good.The common advantage of this type sheet material is that density is high, and intensity is high, and dimensional stability is good, and class is high, although product compression strength and the impact strength processed by such sheet material purely are all good, but makes product easy cracked in stressed meeting on bamboo silk direction.
Summary of the invention
The objective of the invention is provides a kind of bamboo plywood for solving the problems of the technologies described above, and it is big that it has case hardness, and compression strength is high, not easily broken advantage excellent in cushion effect.
Above-mentioned technical purpose of the present invention is achieved through following technical scheme:
A kind of bamboo plywood comprises upper layer, intermediate layer, surface layer down, said upper layer and the following surface layer group bamboo clappers of attaching most importance to, and the bamboo silk orientation of said reorganization bamboo clappers is with vertical from the body face.
In the technique scheme of the present invention; Because upper layer is recombined bamboo plate with following surface layer; Therefore the performance of compression strength and impact strength is all good, causes this sheet material cracked in order to overcome on bamboo silk direction, applying power, and the inventor has increased the intermediate layer and overcome this shortcoming; This intermediate layer can be a plank, also can be the bamboo chip plate.After having increased this intermediate layer, to make upper layer cracked on bamboo silk direction; Except will overcoming resistance intrinsic between the bamboo silk; Also to overcome the stiction that bamboo silk and intermediate layer gummed is produced; The size of this stiction is enough to resist in the daily routines all power that this board product applied, and the intensity in intermediate layer itself is also good, resists stressed impact for a kind of bamboo plywood of product of the present invention support is provided.In addition; The bamboo silk of a kind of bamboo plywood of product of the present invention is with vertical from the body face, so its anti-pressure ability is strong especially, its principle just like to the horizontal application of force of pillar with consistent to its vertical application of force; Make and damage it, then must apply much bigger power to it in the vertical.Because a kind of bamboo plywood global density of product of the present invention is big, intensity is high, dimensional stability good, so a kind of bamboo plywood of the present invention has excellent mechanical property and outstanding external sensory manifestation, class height, the very suitable top-grade furniture of making.
Preferred as technique scheme, the bamboo silk of said reorganization bamboo clappers comprise through charing with without the bamboo silk of charing.
A kind of bamboo plywood that adopts technique scheme to make, surface smoothness is good; Can form irregular texture alternately through charing with without the bamboo silk of charing, therefore not need paster also not need japanning, have outstanding outward appearance performance, can directly process furniture and use.And the bamboo silk after the process charing has the anti-advantage of damaging by worms of anticorrosion.
As the advantage of technique scheme, said intermediate layer is the bamboo strip side compression glued board.
Further preferred as technique scheme, said intermediate layer is an at least one bamboo chip concora crush glued board.
