Abstract

The invention relates to the technical field of chemical environment-friendly adhesives, in particular to an antibacterial and anti-mildew plant adhesive and a preparation method thereof. The antibacterial and anti-mildew plant adhesive is prepared from a component A and a component B, wherein the component A is prepared from the following raw materials: 480-520 parts of soybean protein, 1-2 parts of isothiazolinone compounds, 1-2 parts of N-(2-benzimidazolyl)-methyl carbamate, 0.3-0.7 part of copper dodecylbenzene sulfonate and 0.3-0.7 part of a chelating agent; the component B is prepared from the following raw materials: 380-420 parts of a thermosetting resin solution, 4-10 parts of a denaturant, 4-10 parts of a crosslinking modifying agent, 1.5-2.5 parts of a defoaming agent and 570-600 parts of water. All the raw materials in the adhesive act synergistically, so that the adhesive is good in stability, long-acting and lasting in antibacterial and anti-mildew properties, high in bonding strength and good in fluidity and water resistance.

Description

technical field [0001] The invention relates to the technical field of chemical environmental protection adhesives, in particular to an antibacterial and anti-mildew plant adhesive and a preparation method thereof. Background technique [0002] Adhesives are the blood of my country's wood-based panel industry. As the world's largest country in wood-based panel production, consumption, and import and export trade, China uses more than 6.5 million tons of adhesives for wood-based panel production in terms of solid content each year. The traditional glue types are mainly urea-formaldehyde resin adhesives, melamine modified There are three kinds of "aldehyde-based" synthetic resin adhesives, namely permanent urea-formaldehyde resin and phenolic resin. These adhesives generally have a certain amount of apron release, which is harmful to the health of consumers. In order to overcome the defect of formaldehyde released by aldehyde adhesives, since the 1920s, vegetable protein has ...
