Problems solved by technology

Among them, when the biological adhesive based on animal blood is used for wood-based panels, the cured adhesive layer is relatively hard, has poor water resistance, has a special odor and is prone to mold and mildew
Although some people tried to overcome these shortcomings by adding some preservatives and reinforcing agents, the effect was not good, which affected the popularization and application of bio-adhesives

Abstract

The invention discloses a biological plywood adhesive and a preparation method thereof. The biological plywood adhesive is prepared from, by mass, 5-15 parts of ethyl acrylate, 16-18 parts of dimethylamine, 5-15 parts of butyl acrylate, 2-6 parts of an emulsifying agent, 8-10 parts of diethylenetriamine, 12-14 parts of polyketoamine, 6-8 parts of triethylene tetramine, 13-15 parts of butyl methacrylate, 14-16 parts of polyethyleneimine, 2-4 parts of a drying promoter, 15-17 parts of glycidyl acrylate and 30-50 parts of ammonium hydroxide. The adhesive prepared through the method achieves the bonding strength of I-type adhesives, the water resistance of an adhesive layer is improved, no formaldehyde is contained, the cost is low, and the industrialized promotion value is achieved.

Description

technical field [0001] The invention relates to the technical field of wood board bonding, in particular to a plywood bio-adhesive and a preparation method thereof. Background technique [0002] Wood-based panels mainly include four categories: plywood, particleboard, blockboard and fiberboard, among which plywood is the leading product of my country's wood-based panels. At present, except that the building templates in plywood are made by pressing phenolic glue, others are made by pressing urea-formaldehyde glue or melamine-modified urea-formaldehyde glue. These wood-based panel adhesives all contain formaldehyde. Studies have shown that the formaldehyde release period of wood products made of formaldehyde-containing adhesives used indoors can be as long as 15 years. The lot of documents record, formaldehyde mainly shows aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction to health effects. The...
