Problems solved by technology

[0002] Aldehyde adhesives are used in the largest amount in wood industry adhesives, but they have many disadvantages: the main raw materials are mostly from non-renewable resources such as petroleum and coal; carcinogens (such as formaldehyde) are continuously emitted during production and use, which will harm the human body Healthy; the product is non-degradable and easy to pollute the environment
[0005] The current research methods all focus on modifying the soybean protein in it, but do not involve 40% carbohydrates, causing this component to have no effect on the water resistance of the adhesive after curing, or even have a negative effect, and waste raw materials

Abstract

The invention discloses a polymer-modified soybean-based plate adhesive. The polymer-modified soybean-based plate adhesive is prepared from, by weight, 0.8-2 parts of polyurethane, 1-2 parts of dodecenylsuccinic acid, 0.4-1 part of oleic diethanolamide, 2-4 parts of polyvinyl alcohol, 170-200 parts of defatted soybean powder, 0.3-0.4 part of ferric chloride, 0.1-0.2 part of ferrous chloride, 0.8-1 part of epoxy chloropropane, 2-3 parts of N-hydroxymethyl acrylamide, 16-20 parts of styrene, 0.1-0.2 part of potassium persulfate, 3-4 parts of hemicellulase, 10-19 parts of poly diphenyl methane diisocyanate, 60-70 parts of 20-30% hydrochloric acid solution, 0.3-1 part of resorcinol, 2-4 parts of neutral dinonyl-naphthalenesulfonic aci barium salt, 2-3 parts of pectin and the like. The polymer-modified soybean-based plate adhesive has the advantages of being not likely to cause equipment corrosion, long in shelf life, free of formaldehyde, low in residual monomer content, environmentally friendly, good in water resistance and the like.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a polymer-modified soybean substrate adhesive and a preparation method thereof. Background technique [0002] Aldehyde adhesives are used in the largest amount in wood industry adhesives, but they have many disadvantages: the main raw materials are mostly from non-renewable resources such as petroleum and coal; carcinogens (such as formaldehyde) are continuously emitted during production and use, which will harm the human body Healthy; the product is non-degradable and easy to pollute the environment. Therefore, the research and development of biomass-based adhesives to replace aldehyde-based adhesives has received global attention. Among various biomass materials, soybeans (including genetically modified soybeans) have the characteristics of large yield, low cost, and high plant protein content, and are good raw materials for adhesives; study soybean-based adhesives to make t...
