A high-efficiency leather shoes mildew resistant antimicrobial sustained-release agentia and preparation method thereof

Abstract

The invention relates to a preparation method of a high-efficiency anti-mildew and anti-bacterial slow-release agent for leather shoes. The present invention selects the mixture of thiocyanate and isothiazolinone to form the high-efficiency leather shoes mildew-proof and antibacterial agent. The agent has the characteristics of low toxicity, high efficiency, and broad spectrum, and can be widely used in various fields such as leather, export leather shoes, wood, coatings, etc., and is an environmentally friendly high-efficiency anti-mold and antibacterial agent. Compared with the original antifungal agent, the prepared agent has enhanced its water solubility by utilizing the excellent inclusion and sustained release effect of cyclodextrin on drugs, as well as the natural biocompatibility of cyclodextrin and leather. , The second is that the agent has a slow-release effect, which can greatly prolong the action time of the anti-fungal agent; the third is to reduce the corrosiveness, toxicity and irritating odor of the anti-fungal agent.

Description

technical field [0001] The invention relates to an anti-mildew and anti-bacterial agent for leather shoes, in particular to a high-efficiency anti-mildew and anti-bacterial slow-release agent for leather shoes and a preparation method thereof. Specifically, it relates to a method for preparing a high-efficiency anti-mold and anti-bacterial slow-release agent for leather shoes by using a food-grade substance β-cyclodextrin to include several high-efficiency broad-spectrum anti-fungal agents. Background technique [0002] my country is a big leather producer and a big exporter of leather shoes. According to statistics in 2005, the leather industry can earn more than 12 billion US dollars for the country's exports every year. my country's annual output of leather shoes is about 2.5 billion pairs, accounting for 40% of the world's total output of leather shoes, ranking first in the world. The raw hides used in tanning production are rich in protein, f...

Problems solved by technology

[0003] At present, most of the anti-mold research in China is focused on the research of high-efficiency, natural, and low-toxic drugs, and rarely involves research on functional, slow-release, long-acting, low-residue and other processes and pharmaceuticals.

However, the traditional treatment process is due to the limited binding force of these agents and leather, and the short-term release and residual problems of the agents, the anti-mildew effect is not ideal, and it has different degrees of impact on humans, animals, and the environment. Harm, there is no fungicide without disadvantages

With the increasingly stringent national environmental protection regulations and my country's accession to WTO, many leather antifungal agents that are still widely used have been restricted in use.

In particular, the leather shoes exported by our country have to go through long-term high-humidity and high-temperature sea transportation. This kind of environment can easily cause mildew on leather products such as leather shoes, which seriously affects the export earnings.
