Abstract

The present invention relates to a preparation method of starch glue for wood. Said invention uses starch as main raw material, and adopts the following steps: firstly, making starch undergo the processes of acidolysis, oxidation and graft copolymerization, etc., then adding modifying agent and complexing agent to make cross-linking modification, then heating and gelatinizing, cooling and successively adding the adjuvants of diluent, plasticizer and defoaming agent so as to obtain a starch glue with excellent performance for wood.

Description

technical field

[0001] A preparation method of starch glue for wood belongs to the technical field of adhesive preparation methods. Background technique

[0002] According to the different production materials and production methods of adhesives, wood adhesives can be divided into two categories: natural polymer glue and synthetic polymer glue. Natural polymer adhesives mainly include protein glue and starch glue. The history of using natural adhesives in my country is quite long. Since this kind of adhesive is made of natural materials, most of which are water-soluble. Generally speaking, the bonding strength, water resistance, heat resistance, chemical resistance and other properties are not high. Adhesive products cannot withstand harsh conditions and have a short service life. Therefore, the amount of natural polymer glue used in wood industry adhesives is becoming less and less. At present, synthetic polymer adhesives are mainly used. Among them, the most widely used a...
