Special waterproof antibacterial adhesive for wood products and preparation method thereof

Abstract

The invention provides a special waterproof antibacterial adhesive for wooden products and a preparation method of the special waterproof antibacterial adhesive, and belongs to the technical field ofadhesive. The special waterproof antibacterial adhesive for wooden products is prepared from the following raw materials in parts by weight: 55 to 65 parts of glutinous rice flour, 20 to 28 parts of sweet potato starch, 10 to 15 parts of polyvinyl alcohol, 4 to 6 parts of an anti-corrosion agent, 2 to 3 parts of a waterproof agent, 2.7 to 3.5 parts of an antibacterial agent, 22 to 30 parts of a biological adhesive, and 360 to 380 parts of water. The special waterproof antibacterial adhesive is excellent in comprehensive performance, waterproof, corrosion-resistant, excellent in antibacterial effect and good in stability, and has a good inhibition effect on escherichia coli and staphylococcus aureus.

Description

technical field

[0001] The invention relates to the technical field of adhesives, in particular to a special waterproof and antibacterial adhesive for wood products and a preparation method thereof. Background technique

[0002] With the continuous improvement of people's living standards, the application of wood products is becoming more and more extensive. In the process of making wood products, a large amount of adhesive is needed. Through the adhesion and cohesion of the interface, two or more parts or Materials are joined together. At present, the commonly used adhesives on the market are mainly "tripolymer glue", which will release carcinogens and seriously affect the environment and human health. Subsequently, polyurethane adhesives appeared, which have the advantages of good flexibility and high tensile strength. However, during long-term use, this type of adhesive is affected by its own raw materials and the surrounding environment, which easily leads to bacterial ...
