Problems solved by technology

Most of the commonly used adhesives are synthetic adhesives, such as urea-formaldehyde resin, phenolic resin, etc. These adhesives will release harmful substances such as formaldehyde during use, which will endanger the environment and human health. Therefore, the use of such synthetic adhesives is gradually restricted.

Abstract

The invention discloses a biosynthesis resin, a preparation method thereof and an application of the biosynthesis resin. According to the preparation method, corn protein powder serves as main raw materials, is modified and reacts with lauric acid, malonic acid and sodium carbonate under the alkaline conditions, and sugar alcohol and nano-silicon dioxide are added to prepare the biosynthesis resin. The biosynthesis resin is stable in nature, resistant in water, high temperature and corrosion, free from toxicity and pollution, high in bonding strength and wide in application and can be naturally degraded and can serve as an adhesive and coating.

Description

Technical field [0001] The invention relates to a biosynthetic resin, its preparation method and application. Background technique [0002] Adhesives with different properties are required during the processing and use of the board. The commonly used adhesives are mostly synthetic adhesives, such as urea-formaldehyde resins, phenolic resins, etc. These types of adhesives release harmful substances such as formaldehyde during use, harming the environment and human health. Therefore, the use of such synthetic adhesives is gradually restricted. [0003] In recent years, a kind of biosynthetic resin adhesive has gradually emerged. Biosynthetic resin is a kind of synthetic resin material prepared by modification of natural macromolecules. It has good adhesive properties and is degradable and pollution-free. A good alternative to adhesives. Summary of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a biosynthetic ...
