Abstract

The invention discloses a sheepskin mold preventive, belonging to a leather assistant. The sheepskin mold preventive comprises the following components in parts by mass: 80-120 parts of pure water, 200-238 parts of calcium chloride, 35-40 parts of calcium hydroxide, 110-135 parts of chloral hydrate, 50-65 parts of nitroethane, 150-180 parts of bromine, 450-500 parts of carbon tetrachloride and a right amount of anhydrous sodium sulfate. The sheepskin mold preventive is a halogenated nitroparaffin alcohol compound, can still keep antimicrobial activity in nonionic/anionic surfactants and protein hydrolysates, and can inhibit the sheepskin mold from generation.

Description

technical field [0001] The invention belongs to a leather auxiliary agent, in particular to a sheepskin antifungal agent. Background technique [0002] China's leather industry, after adjusting and optimizing its structure, has initially formed a number of leather production characteristic areas and professional markets throughout the country with clear division of labor, outstanding characteristics, and playing a decisive role in stimulating the local economy. Their formation has laid the foundation for the development of China's leather industry. [0003] In an increasingly competitive market environment, it is not easy for China's leather industry to achieve such achievements, which also proves the vitality and strength of China's leather industry. The market potential of leather and its products is huge. The total global demand for leather is about 100 million square meters. China's leather output is equivalent to nearly 70 million pieces of standard leather, accounting...
