Description
Technical field
The present invention relates to chemical material field, particularly, relate to a kind of adhesion agent for artificial board, and its preparation method and the glued board that utilizes this tackiness agent.
Background technology
Along with the fast development of the industries such as building, decorations, packing, the output of China's wood-based plate rapidly increases.2012,2.86 hundred million square metres of China's wood-based plate ultimate productions, accounted for 50% of Gross World Product.Wherein shaving board is 1,289 ten thousand square metres, increases by 7.2% on a year-on-year basis; 5,554 ten thousand square metres of fiberboards, increase by 13.1% on a year-on-year basis; 1.42 hundred million square metres of glued boards, increase by 18.3% on a year-on-year basis.Wood-based plate ultimate production, glued board output, furniture output and wood floors output occupy No. 1 in the world for years.
The tackiness agent generally adopting in Wood-based Panel Production is that formaldehyde is associated resin, is mainly urea-formaldehyde resin and modified product thereof.Although through effort for many years, China's adhesive of artificial board production level has had large increase, wood-based plate and goods environmental protection characteristic thereof are greatly improved, but wood-based plate and goods (furniture, timber floor and Indoor Wooden finishing material etc.) thereof that many enterprises produce still exist comparatively serious formaldehyde release And Spread of Solute, are the main sources of formaldehyde pollution in room air pollution.
At present, the method for reduction artificial board formaldehyde burst size mainly contains following 4 kinds: 1) adopt low mol ratio modified urea-formaldehyde resin adhesive; 2) in modified urea-formaldehyde resin adhesive, add formaldehyde-trapping agent; 3) wood-based plate is carried out to aftertreatment; 4) adopt other environmental-protection type adhesives.But these technology all exist many defects.For example: 1), although adopt low mol ratio modified urea-formaldehyde resin adhesive can effectively reduce the burst size of methanal of wood-based panel product, the bonding strength of product also often reduces, and can not meet service requirements; And extend set time, production efficiency reduces; 2) in urea-formaldehyde resin for artificial board tackiness agent, add formaldehyde-trapping agent, although can effectively reduce free formaldehyde in artificial plate burst size, often also reduce the bonding strength of wood-based plate simultaneously; Meanwhile, general formaldehyde-trapping agent price is often far away higher than urea-formaldehyde resin adhesive, and it adds and has just improved product cost, has reduced product competitiveness; 3) wood-based plate is carried out to aftertreatment, if publication number is open day of CN1526528(: disclose a kind of manufacturing process that adopts ammonia vacuum method to prepare E1/EO level environment friendly artificial board in application for a patent for invention on September 8th, 2004); Publication number is open day of CN2394770(: in utility model patent on September 6th, 2000), disclose a kind for the treatment of unit that reduces artificial board formaldehyde burst size; These post-treating methods, not only make the manufacturing process of wood-based plate complicated, and finishing apparatus investment are huge, and production cost obviously improves; 4) adopt other environmental-protection type adhesives, as isocyanates tackiness agent, cause the production cost of wood-based plate to increase considerably, producting process difficulty strengthens, enterprise and user are difficult to accept; And, its glued joint the processing of goods after discarded may also have problems (as, during burning, may produce toxic gas prussic acid etc.); The wood-based plate bonding strength that adopts common protein adhesive to prepare is low, and wood-based plate easily comes unglued.In sum, although above-mentioned technique means can effectively reduce free formaldehyde in artificial plate burst size, can not thoroughly solve formaldehyde release And Spread of Solute, or because production cost is crossed high reason and cannot promote.
In addition, the adhesive of artificial board generally adopting at present also all exists the fossil resource Dependence Problem of raw material, does not meet the requirement of Sustainable development.
