Problems solved by technology

However, due to the limitation of its perishable nature, protein adhesives are easy to breed bacteria and cause corruption and decomposition when processing and preparing adhesives, which is not conducive to bonding long-term preserved items.
The corrosion resistance of protein adhesives can be improved through physical and chemical modification, but it cannot fundamentally solve the problem of poor bonding strength of vegetable protein adhesives in cardboard bonding, and the effect of water resistance modification is not obvious

Abstract

The invention relates to a vegetable protein adhesive used for the production of corrugated board. The epoxy succinic acid diester is used as a raw material, and an organic silicon group is used to modify the synthetic surfactant, so as to prepare a modified surfactant with a hydrophobic group. The modified surfactant is used as a modifier to modify vegetable protein to improve its adhesiveness and hydrophobicity. By studying the effect of modifier and the amount of addition, soybean protein isolate adhesive The influence of viscosity, solid content, bonding strength and water resistance, etc., using the pertinence of modifiers, effectively prepare a vegetable protein adhesive with high strength and good water resistance, which is used in the production of corrugated cardboard, which improves the strength and production of cardboard. efficiency.

Description

technical field [0001] The invention relates to the technical field of preparation of an adhesive, in particular to a vegetable protein adhesive used for the production of corrugated cardboard. Background technique [0002] In the field of adhesives, with the development of society, the research, development and use of environmentally friendly adhesives has become the main development trend of today's society. Among them, starch and protein raw materials have a wide range of sources and low cost, and have become the object of widespread concern. Starch adhesives have poor water resistance and high modification costs. [0003] Protein-based adhesives have broad development prospects, especially the advantages of vegetable protein-based adhesives are more significant. The current research on protein-based adhesives is mainly to prepare natural protein glues by adding cross-linking agents and auxiliary agents to proteins for use in the wood industry. However, due to the limit...
