Description
Technical field
The present invention relates to artificial board production, furniture Decoration Industry, more particularly to it is a kind of nontoxic, fire prevention (fire-retardant), water-fast
The production method of artificial board (thin this work plate, glued board, fiberboard etc.) and the glue for making nontoxic plank.
Background technology
Currently, fitting up toxic phenomenon generally existing, and human health is seriously endangered, and artificial board is finishing furniture row
The main material of industry, and main toxic source.The annual artificial board in China (thin this work plate, glued board, fiberboard etc.) production
Amount, since plank contains the noxious materials such as a large amount of free formaldehyde, phenol, cyanide, causes wood-based plate to be given birth at 100,000,000 cubes or more
Production process seriously pollutes environment, and finishing and furniture industry is caused seriously to pollute room air, seriously endangers human health, thus entirely
Ball industry specialists pains find more good method and solve this problem, but do not find more suitably technology so far, only original
On the basis of done a little improvement, but it is to mitigate the content of noxious material to continue to use traditional technique, and timber belongs to easy what is more
Combustion product, plank pollution is more serious if timber impregnates fire retardant.Wood-based Panel Production has following several sides substantially both at home and abroad at present
Method：
1, make adhesive producing artificial board with pollopas.Pollopas is through certain proportion with formaldehyde and urea one
Constant temperature degree, pressure form under the time through chemical addition, since the temperature in chemical reaction process, pressure, the control of time can not
Formaldehyde in glue is all replaced, some total formaldehyde dissociates in glue, this part formaldehyde is slowly after being produced into plank
Distribute pollution air outward, pollopas category water-soluble products, the plank poor water resistance of production, purposes is also restrained.Such as
Floor, outdoor use plank etc..But pollopas raw material is easy to get, it is cheap at present both at home and abroad mostly in this way.
2, since floor and outdoor use plate person require certain water resistance, scientists it has been investigated that phenol through breaking
Change to combine with urine aldehyde and generate phenolic resin, can not only reduce content of formaldehyde, but also water resistance can be improved, meet the water-fast of floor and want
It asks, but since more expensive of starting phenol uses in specific purposes, the face layer that can not also solve plank is stained with and is connect, and phenol is also
Noxious material, the plank formaldehyde produced reduce, but phenol content increases, and overall toxicity does not weaken.
3, it is come up with again using carbimide replacement urine aldehyde and phenolic resin to change the domestic and international scientist of above-mentioned condition
Production plank succeeds.The content of formaldehyde of plank substantially reduces, but carbimide contains cyanide, cyanide category violent in toxicity
Product, production process effect on environment is very big, and since carbimide wants hot setting energy consumption big, the face layer that can not also solve plank is stained with
It connects, can be used only in the high temperature compacting production of base material and wood powder, wood shavings chips.Also the eighteenth of the twenty is expensive for price, and foreign countries have stopped using.
4, in order to thoroughly solve the above problem of plank, industry specialists come up with again is covered with plastic film on wood chip, plastic cement
Film is heated that wood chip is dissolved to be stained with and is connected together, i.e., is covered with the comparable plastic film of the size cut in advance and is heated between wood chip
It pressurizes.Because plastic cement does not have the harmful substances such as formaldehyde, this solves the toxic present situations of plank, but due to plastic cement
The disconnected row of film heat shrinkable, cause plank hollowing, defect rate to increase, and cost increases, and auxiliary film is also more difficult, equally can not also do face layer
Be stained with and connect, practical finished product can only exempt to be up to state standards by force, also be unable to reach the requirement of modern nontoxic finishing.
