Quick-drying plant protein board adhesive and preparation method thereof

Abstract

The invention discloses quick-drying plant protein board adhesive. The quick-drying plant protein board adhesive comprises the following raw materials in parts by weight: 0.4-1 part of zinc hydroxystannate, 0.5-1 part of oleic diethanolamide, 1-2 parts of inositol hexaphosphate, 0.4-1 part of polyglycerol fatty acid ester, 1-2 parts of citric acid, 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 phenylethylene, 0.1-0.2 part of potassium peroxodisulfate, 3-4 parts of hemicellulase, 10-19 parts of polydiphenyl methane diisocyanate, 60-70 parts of a hydrochloric solution with the concentration of 20-30%, 2-3 parts of tetrabutyl titanate, 0.6-1 part of saturated octadecanoylamide, 1-2 parts of cellulose propionate and the like. The quick-drying plant protein board adhesive has the characteristics of being unlikely to cause equipment corrosion, relatively long in pot and storage life, free of formaldehyde, low in residual monomer content, good in water resistance and the like.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a quick-drying vegetable protein plate 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...

However, DSF is a complex mixture consisting of nearly 50% soy protein, 40% carbohydrates and other minor components; current research methods focus on modifying soy protein without involving 40% carbohydrates, As a result, this component has no effect on the water resistance of the adhesive after curing, or even has a negative effect, and wastes raw materials
