Soybean-base bone glue panel adhesive and preparation method thereof

Abstract

The invention discloses a soybean-based bone glue plate adhesive, which is composed of the following raw materials in parts by weight: calcium lactobionate 1-2, coconut acid diethanolamide 0.7-1, bone glue 6-8, naphthene Acid soap 0.6‑1, diphenylsilanediol 3‑4, zinc dibutyldithiocarbamate 1‑2, polyvinyl alcohol 2‑4, defatted soybean flour 170‑200, ferric chloride 0.3‑0.4, Ferrous Chloride 0.1‑0.2, Epichlorohydrin 0.8‑1, N‑Methylol Acrylamide 2‑3, Styrene 16‑20, Potassium Persulfate 0.1‑0.2, Hemicellulase 3‑4, Polymerase Phenylmethane diisocyanate 10-19, 20-30% hydrochloric acid solution 60-70, isothiazolinone 0.1-0.2, trinonylphenyl phosphite 0.8-1. The invention has the characteristics of not easy to cause equipment corrosion, long storage period, no formaldehyde, low residual monomer content, good water resistance and the like.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a soybean-based bone glue sheet 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 them r...

[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
