Abstract

The invention discloses an oxidized starch adhesive and a preparation method thereof. The oxidized starch adhesive is mainly prepared from the raw materials of, by weight, 100 parts of starch, 3-5 parts of hydrogen peroxide, 0.1-0.5 parts of a potassium permanganate solution, 0.4-1 part of s catalyst, 9-11 parts of sodium hydroxide, 1-3 parts of a crosslinking agent, 300-500 parts of water, and 0-0.5 parts of a defoaming agent. According to the invention, hydrogen peroxide and the potassium permanganate solution are both used as oxidizing agents, and cooperates to provide a synergistic effect in carrying out oxidization treatment upon the starch material. The oxidization speed is high, and the dose of oxidizing agent is low. The obtained oxidized adhesive has the advantages of high bonding strength, good stability, good gelling resistance, long storage time, short drying time, good environment friendliness, and low cost. The adhesive is nontoxic and harmless, and can be widely applied in the fields of papermaking, trademark, textile, and the like.

Description

technical field

[0001] The invention belongs to the technical field of starch adhesives, in particular relates to an oxidized starch adhesive, and also relates to a preparation method of the oxidized starch adhesive. Background technique

[0002] Starch adhesive is highly valued by people in the industry due to its advantages of rich raw material sources, low cost, low investment, quick results, non-toxic and tasteless products, simple production process, and easy mechanized production. An important type of rubber that is indispensable to departments and daily life. Although starch can be used as an adhesive after being heated and gelatinized by adding water, its viscosity will be high even if the concentration or solid content is very low, which is unfavorable for processing and use, so their direct use as an adhesive is limited.

[0003] Widely used starch-based adhesives are generally prepared by degradation conversion or chemical oxidation of starch. In the prior art, ...
