Abstract

A preparation method of a terbinafine hydrochloride microcapsule antibacterial agent for shoes comprises the steps: with chitosan and Arabic gum as a wall material and a terbinafine hydrochloride emulsifiable paste as a core material, dispersing the terbinafine hydrochloride emulsifiable paste in a capsule wall material aqueous solution, regulating a pH value, allowing the positively charged chitosan and the negatively charged Arabic gum to generate an electrostatic effect, attracting each other, then making the solubility reduced, generating phase separation, forming a gel layer, precipitating the gel layer around the core material, and finally adding glutaraldehyde to make the obtained microcapsule cured. The prepared terbinafine hydrochloride microcapsule has uniform distribution of particle size, is regularly spherical in shape, can better penetrate into the interior of fiber, and achieves the purpose of lasting bacteria resistance whenever and wherever possible; and the prepared microcapsule also has antifungal and antibacterial performance, is more suitable for shoe material bacteria resistance, and has the characteristics of being simple and easy to implement.

Description

technical field [0001] The invention relates to a preparation method of microcapsules, in particular to a preparation method of terbinafine hydrochloride microcapsule antibacterial agent for shoes. Background technique [0002] Shoes are a must-have in people's daily life. During wearing, due to the airtightness of the shoe cavity, the germs on the skin of the feet multiply in large numbers, which can easily cause skin infections, and then cause foot diseases. With the progress of society and the continuous improvement of people's living standards, people have higher and higher requirements for the comfort performance and hygienic performance of shoes and boots. However, most of the existing antibacterial shoe materials have good antibacterial effects on typical bacteria such as Escherichia coli and Staphylococcus aureus, but have no obvious effect on fungi such as Candida albicans and Trichomonas rubrum that really cause foot diseases. [0003] Antibacterial microcapsules ...
