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

Embodiment Construction

[0024] A sound-insulating soybean-based substrate adhesive, which is composed of the following raw materials in parts by weight:

[0025] 2 Mercaptobenzimidazole 0.7, dibutyl phthalate 0.1, polyvinyl alcohol 2, defatted soybean powder 170, ferric chloride 0.3, ferrous chloride 0.1, epichlorohydrin 0.8, N methylol acrylamide 2. Styrene 16, potassium persulfate 0.1, hemicellulase 3, polydiphenylmethane diisocyanate 10, 20% hydrochloric acid solution 60, calcium zeolite powder 3, sodium alkylbenzene sulfonate 0.8, trimethylol Propane 0.4, carbon nanotube 1, tin sulfide 0.1, hexamethylphosphoric triamide 0.8.

[0026] A preparation method of the sound-insulating soybean-based substrate adhesive, comprising the following steps:

[0027] (1) Mix the above-mentioned ferric chloride and ferrous chloride, add to 20% hydrochloric acid solution, stir evenly to obtain ferric salt solution;

[0028] (2) Put the above-mentioned calcium zeolite powder into 10% hydrochloric acid solution, s...

Abstract

The invention discloses a sound insulating soybean-based plate adhesive. The sound insulating soybean-based plate adhesive is prepared from, by weight, 0.7-2 parts of 2-benzimidazol-y-yl disulphide, 0.1-0.2 part of dibutyl phthalate, 2-4 parts of polyvinyl alcohol, 170-200 parts of degreased soybean meal, 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, 3-4 parts of scolecite powder, 0.8-1 part of sodium alkyl benzene sulfonate, 0.4-1 part of trimethylolpropane, 1-2 part of carbon nano tubes and 0.8-1 part of hexamethylphosphoramide. The sound insulating soybean-based plate adhesive has the advantages of being not prone to cause equipment corrosion, long in working life and deposit term, free of formaldehyde, low in residual monomer content, good in water tolerance and the like.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a sound-insulating 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 ma...
