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 an environment-friendly soybean-based plate adhesive. The environment-friendly soybean-based plate adhesive is prepared from raw materials in parts by weight as follows: 0.7-1 part of sodium myrastate, 0.8-1 part of stearamide, 2-4 parts of polyvinyl alcohol, 170-200 parts of degreased soybean meal, 0.3-0.4 parts of ferric chloride, 0.1-0.2 parts of ferrous chloride, 0.8-1 part of epichlorohydrin, 2-3 parts of N-hydroxymethyl acrylamide, 16-20 parts of styrene, 0.1-0.2 parts of potassium persulfate, 3-4 parts of hemicellulose, 10-19 parts of poly(4,4'-diphenylmethane diisocyanate), 60-70 parts of a 20%-30% hydrochloric acid solution, 0.6-1 part of dodecyl glycoside, 1-2 parts of stannous sulfide, 0.5-1 part of 2-ethylhexyl acrylate, 2-3 parts of phosphocellulose, 0.2-1 part of dimethylformamide and 3-5 parts of poly(ethylene glycol) adipate. The environment-friendly soybean-based plate adhesive has the characteristics that equipment corrosion is not easily caused, the application period and the storage period are longer, no formaldehyde is produced, the content of residual monomers is low, the water resistance is good and the like.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an environmentally friendly 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 ...
