Leather fungicide and preparation method thereof

Abstract

The invention discloses a leather fungicide and a preparation method thereof. The leather fungicide is prepared from raw materials in percentage by mass as follows: 1%-20% of propiconazole, 1%-25% ofsodium pyrithione, 1%-15% of iodopropynyl butylcarbamate, 1%-10% of an emulsifier and the balance of a solvent. The preparation method of the leather fungicide is quite simple, and all that is required is to mix the materials sufficiently and uniformly. The leather fungicide contains three active components including propiconazole, sodium pyrithione and iodopropynyl butylcarbamate, and the three active components have different antimicrobial active groups, so that the antimicrobial spectrum of the leather fungicide is greatly expanded; besides, the three active components have obvious synergistic interaction effect, therefore, growth of diversified mould groups on wet blue leather is inhibited, and the common problem of drug resistance of the existing leather fungicide is solved.

Description

technical field [0001] The invention relates to a leather antifungal agent and a preparation method thereof. Background technique [0002] Natural leather is rich in protein and lipids, and is vulnerable to fungal attack and erosion during tanning and storage, which will greatly affect the quality and appearance of leather. In order to prevent leather and leather products from becoming moldy, the usual way is to add antifungal agents to inhibit the growth of fungi in the tanning process. The traditional leather antifungal agent trichlorophenol has been banned due to environmental safety issues. At present, the commonly used antifungal agent in the industry is 2-thiocyanomethylthiobenzothiazole (TCMTB), which is a kind of antifungal agent developed by Buckman Company of the United States. High-efficiency and environmentally friendly anti-fungal agent. However, due to the long-term use of the antifungal agent in the industry, the resistance of the fungi has become stronger a...

Problems solved by technology

However, due to the long-term use of the antifungal agent in the industry, the resistance of fungi has become stronger and stronger, and the antifungal effect of the antifungal agent has been greatly reduced, which is difficult to meet actual needs

In response to this problem, US 6110950 discloses a composition containing propiconazole and 2-thiocyanomethylthiobenzothiazole, and US 20060014810 discloses a composition containing 2,4,4'-trichloro-2' - the composition of hydroxydiphenyl ether (triclosan) and 4-tolyl-diiodomethyl sulfone, these two kinds of compositions can be used for leather anti-mold, but anti-mold effect is all not ideal enough, is difficult to meet actual demand
