Abstract

The invention discloses the modifier and addition agent of trialdehyde resin glue to reduce free aldehyde and cost. The method comprises the following steps: using seed capsule as raw material, inflating the seed capsule, dissolving, activating, modifying, cross bonding, grafting, adjusting viscosity, and getting the product. The invention has the advantages of decreasing odour in workplace, reducing cost, and improving bonding strength. The invention can be uses as copolymerization modifier and increment removing aldehyde addition agent.

Description

technical field [0001] The invention belongs to fine chemical products, adhesives, adhesive additives and copolymerization materials. The chemical properties of the material of the present invention belong to natural polymer substances. The product of the invention is an environment-friendly product, which can reduce the free formaldehyde of trialdehyde resin glue (urea-formaldehyde resin, melamine-formaldehyde resin and phenolic resin) and reduce the release of toxic formaldehyde from wood-based panels. Background technique [0002] At present, trialdehyde resin glue is an adhesive widely used in the production of man-made panels all over the world. So far, there is no structural adhesive with better cost performance than trialdehyde glue to completely replace trialdehyde glue. Japan uses isocyanate glue instead of urea-formaldehyde glue, and the price is urea-formaldehyde glue. 4-8 times of that, it can only be used in a small area. The present invention, however, can si...
