Research on Starch Adhesive

2020.11.30

The demand for environmentally friendly materials continues to increase, and the development of environmentally friendly, low-cost and excellent performance adhesive materials has become one of the goals that people pursue. Starch adhesives have become an ideal substitute for traditional synthetic resin adhesives due to their wide range of raw material starch sources, low price, natural non-irritation and simple production process. However, due to its own structure and other reasons, starch adhesives have poor water resistance, low solid content, and short pot life, which have become shortcomings restricting their development. For this reason, it is necessary to carry out modification research on starch adhesives. There are common methods such as physical modification, chemical modification and biological modification. Among them, starch adhesives with different properties developed through chemical modification are widely used.

 

Chemical modification is a method that uses different chemical reagents to react with starch to change the physical and chemical properties of starch. It is also the most widely used starch modification method. Chemical modification has many advantages such as easy reaction control and molecular structure design.

 

The use of starch adhesives can be improved by introducing some groups into the original starch by chemical modification methods or changing the number of original hydroxyl groups and glycosidic bonds. Three commonly used chemical modification methods such as oxidation, esterification and crosslinking can improve the bonding strength, thermal performance and water resistance of native starch adhesives to a certain extent, so as to meet the requirements of use.
