Problems solved by technology

Mold is the main cause of mildew in leather garments, and humidity is the root cause of mold reproduction, causing serious economic losses
The growth of mold on the leather will cause the leather to lose its luster in mild cases, and the enzymes secreted by the mold in severe cases will corrode the leather fibers, causing brittle cracks and mildew on the grain surface, reducing the physical and mechanical properties of the leather and shortening the service life of leather products.
Antifungal agent is particularly important for leather, but although the current antifungal agent on the market can temporarily kill mold, the effect is short and cannot achieve long-term antifungal effect

Embodiment 1

[0012] A leather antifungal agent, comprising the following components in parts by weight: 4 parts of absolute ethanol, 3 parts of propylene glycol, 20 parts of litsea cubeba oil, 5 parts of hydroxide, 10 parts of sodium hypochlorite, polyoxygen 5 parts of ethylene alkyl phosphate, 3 parts of diethanolamide cocoate, 2 parts of thickener, 40 parts of water.

[0013] Described hydroxide is sodium hydroxide.

[0014] Described thickening agent is carboxymethyl cellulose.

[0015] The preparation method of the leather antifungal agent is to pour absolute ethanol, propylene glycol hydroxide, and sodium hypochlorite into water and put them into a reactor, stir for 8 minutes, add polyoxyethylene alkyl phosphate, diethyl cocoate Stir for amide and thickener for 10 minutes, then heat to 50-60°C, add litsea cubeba oil and stir for 5 minutes, and cool down to room temperature to obtain a leather antifungal agent.

Embodiment 2

[0017] A leather antifungal agent, comprising the following components in parts by weight: 7 parts of absolute ethanol, 5 parts of propylene glycol, 25 parts of litsea cubeba oil, 6 parts of hydroxide, 12.5 parts of sodium hypochlorite, polyoxygen 7.5 parts of vinyl alkyl phosphate, 4 parts of diethanolamide cocoate, 3 parts of thickener, 45 parts of water.

[0018] Described hydroxide is sodium hydroxide.

[0019] Described thickening agent is carboxymethyl cellulose.

[0020] The preparation method of the leather antifungal agent is to pour absolute ethanol, propylene glycol hydroxide, and sodium hypochlorite into water and put them into a reactor, stir for 9 minutes, add polyoxyethylene alkyl phosphate, diethyl cocoate Stir for amide and thickener for 13 minutes, then heat to 50-60°C, add litsea cubeba oil, stir for 8 minutes, and cool down to room temperature to obtain a leather antifungal agent.

Embodiment 3

[0022] A leather antifungal agent, comprising the following components in parts by weight: 10 parts of absolute ethanol, 7 parts of propylene glycol, 30 parts of litsea cubeba oil, 7 parts of hydroxide, 15 parts of sodium hypochlorite, polyoxygen 10 parts of ethylene alkyl phosphate, 5 parts of coconut acid diethanolamide, 4 parts of thickener, 50 parts of water.

[0023] Described hydroxide is potassium hydroxide.

[0024] Described thickening agent is carboxymethyl cellulose.

[0025] The preparation method of the leather antifungal agent is to pour absolute ethanol, propylene glycol hydroxide, and sodium hypochlorite into water and put them into a reactor, stir for 10 minutes, add polyoxyethylene alkyl phosphate, diethyl cocoate Stir for amide and thickener for 15 minutes, then heat to 50-60°C, add litsea cubeba oil, stir for 10 minutes, and cool down to room temperature to obtain a leather antifungal agent.

Abstract

The invention discloses a leather mildew preventive.The leather mildew preventive is prepared from, by weight, 4-10 parts of absolute ethyl alcohol, 3-7 parts of propylene glycol, 20-30 parts of litsea cubeba oil, 5-7 parts of hydroxide, 10-15 parts of sodium hypochlorite, 5-10 parts of polyoxyethylene alkyl phosphate ester, 3-5 parts of coco fatty acid diethanol amide, 2-4 parts of thickener and 40-50 parts of water.The leather mildew preventive has the effect of integrating sterilization, hydrophobicity, waterproofness and permeability resistance, can rapidly and completely remove mould, and achieves a long-acting mould-proof effect.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a leather antifungal agent. Background technique [0002] Leather goods are commonly used in daily life. Leather is a natural polymer processed product. Its main components are collagen and fat. In addition, a large amount of animal fats, inorganic salts, and casein are added during the processing, which become the nutrient source for mold growth. Mold is the main cause of mildew in leather garments, and humidity is the root cause of mold reproduction, causing serious economic losses. The growth of mold on leather will cause the leather to lose its luster in mild cases, and the enzymes secreted by the mold in severe cases will erode leather fibers, causing brittle cracks and mildew on the grain surface, reducing the physical and mechanical properties of leather and shortening the service life of leather products. Antifungal agents are particularly important f...
