Problems solved by technology

Organic synthetic adhesives include thermosetting resins such as phenolic resin glue, thermoplastic resins such as polyvinyl acetate, and synthetic rubber. There are often a large amount of harmful organic substances in synthetic adhesives, and the volatilization period is relatively long. Natural rubber includes starch, protein glue, and natural rubber. etc. Starch adhesives for wood in traditional natural rubber have low viscosity, poor stability, easy cracking, and high cost. Therefore, how to improve the cohesiveness of starch-based natural rubber is a major research topic in recent years.

Abstract

The invention discloses a planting type food mixed adhesive for wood. The planting type food mixed adhesive for the wood is prepared from the following raw materials in percentage by weight: 10%-30% of lotus root starch, 15%-35% of rice flour, 10%-25% of high gluten wheat flour, 10%-25% of germinant wheat powder, 3%-8% of soybean flour, 10%-20% of hydrated lime powder and 0.1%-1% of a cross-linking agent. The adhesive and a preparation method are unique, non-toxic and high in cohesiveness.

Description

technical field [0001] The present invention relates to an adhesive. Specifically, it relates to a plant-food mixed adhesive for wood and a preparation method thereof. Background technique [0002] With the development of the economy, people's living standards continue to improve, and more and more attention is paid to the environmental protection of wood and other decoration materials. However, the highest standards for wood products in the market and the country's environmental protection requirements are E0 and E1. In fact, until now, many None of the products meet the national standard, the main reason being that the adhesive used in wood is an organic synthetic adhesive. Organic synthetic adhesives include thermosetting resins such as phenolic resin glue, thermoplastic resins such as polyvinyl acetate, and synthetic rubber. There are often a large amount of harmful organic substances in synthetic adhesives, and the volatilization period is relatively long. Natural rubb...
