Abstract

The invention relates to a gelatinized starch adhesive and a preparation method thereof. The gelatinized starch adhesive is mainly composed of starch, nickel sulfate, sodium hydroxide, sodium hypochlorite, sodium thiosulfate, borax, tributyl phosphate and water. The gelatinized starch adhesive has the characteristics of low price, simple compound process, strong adhesion, good fluidity, no toxic or odor and fast drying.

Description

technical field [0001] The invention relates to a gelatinized starch adhesive and a preparation method thereof, belonging to the technical field of compound modified starch. Background technique [0002] General gelatinized starch adhesive is the adhesive commonly used in the export carton product packaging industry at present, but because of its adhesive strength, storage period, environmental protection and other indicators are not ideal, the preparation method is cumbersome, and the environmental temperature, High humidity requirements require constant temperature and humidity equipment for preparation, as well as disadvantages such as long preparation time and cycle. [0003] The invention determines a brand-new formula, which not only satisfies the production requirement, but also improves the production efficiency. Contents of the invention [0004] The purpose of the present invention is to provide a low-cost, simple compounding process for the defects of the exist...
