Fireproof soybean-based plate adhesive and preparing method thereof

Abstract

The invention discloses a fireproof soybean-based plate adhesive. The fireproof soybean-based plate adhesive is prepared from, by weight, 3-4 parts of zinc hydroxystannate, 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 diphenylmethane 4,4'-diisocyanate, 60-70 parts of a hydrochloric acid solution with the concentration of 20-30%, 1-2 parts of deca-brominated diphenyl ether, 0.6-1 part of polyphthalamide, 2-3 parts of diacetone alcohol, 0.7-1 part of triethanolamine borate and the like. The styrene copolymerization modified soybean-based adhesive has the advantages of being not likely to cause corrosion of equipment, long in shelf and storage period, free of formaldehyde, low in content of residual monomers, high in environment friendliness and water resistance and the like.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a fire-resistant soybean base material 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...

[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
