Description
Technical field
The present invention relates to technical field of adhesive, be specifically related to a kind of protection against corrosion moistureproof bamboo wood processing tackiness agent.
Background technology
To synthesize the new type bonding agent-synthesis macromolecule glue of material based on polymer, most widely used general and to have what represent meaning be most formaldehyde system tackiness agent, comprise urea-formaldehyde resin adhesive, Phenol aldehyde resin and trimeric cyanamide.Wherein urea-formaldehyde resin adhesive consumption is maximum, accounts for about 80% of formaldehyde system binder dosage, accounts for 60% of bamboo wood tackiness agent total flow.The advantages such as this kind of tackiness agent is little with its molecular weight, wettability good, bonding strength is high are developed rapidly, instead of natural glue very soon, have captured wood adhesive market.Urea-formaldehyde resin compared to the poor water resistance of resol, melamine resin, mainly due to urea-formaldehyde resin after hardening, still there is-CONH-the group of hydrophilic-CH2OH ,-OH and facile hydrolysis in structure.Current state, inside and outside research modification mainly by adding properties-correcting agent copolymerization, blended, change the water resistance of resin.But, formaldehyde system tackiness agent has fatal defect, because one of its main raw material is formaldehyde, glued joint wood working product with it and inevitably discharge the obnoxious flavoures such as free formaldehyde in manufacture and usage process, harm producers and consumers's is healthy, live in for a long time in the environment of high-concentration formaldehyde pollution, can produce various chronic disease, serious can be carcinogenic.Now, environmental quality is more and more paid attention in countries in the world, and the environmental consciousness of people constantly strengthens; Along with the rapid growth of China's economy, the generally raising of people's living standard, also more and more exquisite to living environment, burst size of methanal receives very big concern.
Native starch tackiness agent so that its raw material sources are wide, cheap, production technique is simple, easy to use, environment-protecting asepsis and be widely used in all conglomeraties, especially use in a large number in Packaging Box, corrugated board production, but it is then rare that Starch Adhesive is used for bamboo carpenter industry, topmost reason is the bonding strength of Starch Adhesive, water tolerance also has erosion resistance all poor, utilize the bamboo product that it bonds, its dry strength is wet tenacity wretched insufficiency generally, can not meet the service requirements of product.
