Abstract

The invention relates to a preparation method of a chitosan leather mildew-proof new material. The preparation method comprises the steps that by weight, carboxymethyl chitosan, 2-[2-(2-hexanoyloxyethoxy)ethoxy]ethyl hexanoate, 1,3-adamantanediol diacrylate, yttrium pyrosilicate, N-butylsulfonate pyridinium tosylate ionic liquid, calcium lignosulfonate, ethanol, benzoyl peroxide and gelatin are added into a reaction kettle, heated and stirred, and then the chitosan leather mildew-proof new material is obtained.

Description

technical field [0001] The invention relates to a preparation method of an antifungal agent, in particular to a preparation method of a chitosan leather antifungal new material. Background technique [0002] With the improvement of people's living standards, the amount of leather is increasing. However, the raw hides used in tanning production are rich in nutrients such as protein and fat, and are very vulnerable to the invasion of microorganisms during preservation. Although the processed leather has increased resistance to microorganisms, mildew will still occur, especially in the leather production process, a large amount of fatliquor produced with natural oils is introduced, and they are also breeding grounds for microorganisms to multiply. In addition, the porosity and polar structure of the leather structure make it easy to absorb moisture, and the leather is acidic. All of the above reasons constitute the basic conditions for mildew. White, blue, yellow and black c...
