Rubber-powder-containing soybean-base board adhesive and preparation method thereof

Abstract

The invention discloses a rubber-powder-containing soybean-base board adhesive which is prepared from the following raw materials in parts by weight: 0.1-0.3 part of hexamethylcyclotrisiloxane, 1-2 parts of waste rubber powder, 2-4 parts of polyvinyl alcohol, 170-200 parts of defatted soybean flour, 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 polydiphenylmethane diisocyanate, 60-70 parts of 20-30% hydrochloric acid solution, 2-3 parts of aluminum tripolyphosphate, 0.1-0.2 part of phytate, 1-2 parts of saturated octadecacarbamide, 2-3 parts of phosphorus tetrahydroxymethylsulfate, 0.3-1 part of octyl isothiazolinone and the like. The rubber-powder-containing soybean-base board adhesive can not easily cause equipment corrosion, and has the characteristics of long shelf life and storage period, no formaldehyde, low residual monomer content, favorable water resistance and the like.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a soybean base material adhesive containing rubber powder 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 adhesiv...

[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
