Description
Technical field
The present invention relates to a kind of utilize soybean protein glue to produce core-board and process, belong to plank manufacture technology field.
Background technology
Along with the fast development of China's economy since last century the eighties, the particularly rapid emergence of China's real estate, almost reach the degree do not filled without room at present, formaldehyde, phenolic aldehyde plank and furniture thereof enter indoor environment in a large number because of decorations, and benzene, the able-bodied problem of aldehyde grievous injury people also significantly present.
Core-board needs log rotary cutting to be slit into veneer in process of production, again synthetic plate again, reconfigure to make these veneers, adhesive must be used, at present, the core batching of tradition adhesive and primary raw material are formaldehyde, phenolic aldehyde, phenol, dimethylbenzene etc., and these industrial chemicals can cause serious harm to human body, the deadly defect of Here it is current wood-based plate.
Therefore, utilize soybean protein glue to produce core-board, greatly develop environmental protection, without the wood-based plate of benzene without aldehyde, improve product technology content, thoroughly solve the active demand that the harm problem of house decorative material to human body becomes people.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of utilize soybean protein glue to produce core-board and process.
The core-board utilizing soybean protein glue to produce and a process, containing following steps;
Step 1, central layer make: dry plate material, double surfacer, multiple blade saw, briar, gluing, finger are rectangular, hot pressing, Puttying, sanding, central layer.
Step 2, openpore make: poplar skin (selected), gluing, cold pressing, another side gluing, cold pressing, have a shave, hot pressing, naturally dry, Puttying, naturally dry, sanding, secondary Puttying, naturally dry, secondary sanding, openpore.
Step 3, paste large poplar skin: openpore, gluing, subsides large poplar skin (two-sided), hot pressing, naturally dry, polishing, saw limit.
Step 4, finished product make: large white poplar semi-finished product, paster (or other), hot pressing, saw limit, Hou Dao (repairing), coding, finished product.
Finished product is core-board of the present invention, and parameter is as follows:
Moisture content: 6.0-14%;
Burst size of methanal :≤0.5mg/L;
Bending strength: single test specimen >=12.0MPa;
Mean value >=15.0MPa;
Preferred core-board of the present invention, parameter is as follows:
Moisture content: 6.8%;
Burst size of methanal: E
0:≤0.05mg/L;
Bending strength: single test specimen >=22.0MPa;
Mean value >=28.3MPa.
A kind of core-board utilizing soybean protein glue to produce, first legumin glue-line 1 is had between central layer 6, central layer 6 and first legumin glue-line 1 combine the combination center plate of rear formation central layer 6 and first legumin glue-line 1, have second largest legumin glue-line 5 between the end face of combination center plate and openpore layer 4, the another side of openpore layer 4 is connected with the first wooden cortex 3; The third-largest legumin glue-line 2 is had between the bottom surface of combination center plate and the second wooden cortex 7.
Advantage of the present invention produces " soybean protein glue ", is the key element manufacturing environment friendly artificial board.The gelation of soybean can make soybean protein isolate have higher viscosity, plasticity and elasticity, due to the adhesive not pernicious gas such as Diazolidinyl Urea that soybean protein isolate is formed, is the adhesive of high-environmental.But common soybean adhesive, its poor water resistance, bonding strength are low, corrosion-resistant, are easy to biodegradation, and this is a difficult problem of all not capturing in decades in the world.Brand-new process route is applied in this invention, by the series of processes such as protein-modified, capture this difficult problem, the dregs of beans stayed after selecting soybean squeezing, as bio-based adhesive, be applied to manufacture and the production of wood-based plate, taken a fancy to the protein content that it has 43%-48% exactly, this is one of key factor improving adhesive viscosity.
In investigation and comparison test, with the core-board that soybean adhesive, its is produced, good more than the wood-based plate water resistance manufactured with formaldehyde, phenol adhesive, bonding strength is high, artificially do not add, also do not produce the noxious materials such as formaldehyde, phenol, melamine, isocyanates, toluene, dimethylbenzene, bean gum does not discharge noxious material.
The present invention is for common core-board, and the thin plank of bean gum has other incomparable advantage characteristic:
1, health environment-friendly: not containing formaldehyde and benzene homologues, it is real health environment-friendly plank, without free formaldehyde release, the most high-environmental class criteria of super European E0 level (0.5mg/L) and JAS Japanese Agricultural Standard F four-star (0.3mg/L), burst size of methanal is no more than 0.1 milligram/m after testing
3, can be called it is zero formaldehyde.Every technic index is all better than existing sheet material, and cost performance is high.
2, relative to solid wood, economize on resources, profile is more elegant in appearance.
3, compression ratio is larger than common multi-layer sheet, plate cored structure is tightr, packing is higher, nail-holding ability is stronger, sheet material bending and compressive strength is higher.
4, sheet material moisture content is low, does not expand, shrink-proof, indeformable.
5, adopt soybean protein glue to be adhesive, protein adhesive volatility is low especially, does not come unstuck.
6, the core-board excellent in resistance to boiling water made, is up to state standards completely to the requirement of II class glued board.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by referring to detailed description below, more completely can understand the present invention better and easily learn wherein many adjoint advantages, but accompanying drawing described herein is used to provide a further understanding of the present invention, form a part of the present invention, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention, as schemed wherein:
Fig. 1 is structural representation of the present invention.
Fig. 2 is texture edge schematic diagram of the present invention.
Below in conjunction with drawings and Examples, the present invention is further described.
Detailed description of the invention
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present invention belong to protection scope of the present invention.
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of core-board utilizing soybean protein glue to produce, first legumin glue-line 1 is had between central layer 6, central layer 6 and first legumin glue-line 1 combine the combination center plate of rear formation central layer 6 and first legumin glue-line 1, have second largest legumin glue-line 5 between the end face of combination center plate and openpore layer 4, the another side of openpore layer 4 is connected with the first wooden cortex 3; The third-largest legumin glue-line 2 is had between the bottom surface of combination center plate and the second wooden cortex 7.
The core-board utilizing soybean protein glue to produce revolutionizes to be only had chemical glue in the world and without the history of real natural plant gum, has started the plank environmental protection New Times.For large-scale industrial production soybean protein bakelite plate series of products have established solid technical foundation.The plank (being called for short bean gum plank) adopting soy protein adhesives to produce, not containing formaldehyde and benzene homologues, health environment-friendly, 100% is nontoxic, and burst size of methanal is no more than 0.1mg/L, meets the strictest F4 asterisk in the world accurate, can be called it is formaldehydeless.
As mentioned above, embodiments of the invention are explained, but as long as do not depart from inventive point of the present invention in fact and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, such variation is also all included within protection scope of the present invention.
