Abstract

The invention relates to a copper-based antibacterial masterbatch and a preparation method thereof. The preparation method comprises the steps of mixing a soluble cuprous salt with water, adding mesoporous zirconium silicate to perform immersion adsorption to obtain a mixture; mixing and adding thiosulfate, metaphosphate and water into the obtained mixture, performing drying after the reaction, and obtaining cuprous ion-loaded zirconium silicate powder; mixing a carrier resin, a dispersing agent, a processing aid and the cuprous ion-loaded zirconium silicate powder and then performing extrusion pelleting, and obtaining the copper-based antibacterial masterbatch. A fiber obtained according to a conventional spinning process by the copper-based antibacterial masterbatch obtained through themethod has excellent antibacterial property and not only has good oxidation resistance, but also has excellent washing resistance, the preparation method is simple and convenient to operate, efficient, low in cost and lasting in effect and has a broad application prospect.

Description

Technical field [0001] The invention relates to the field of preparation of antibacterial masterbatch fibers, in particular to copper-based antibacterial masterbatch and a preparation method thereof. Background technique [0002] Today's social extreme environment, environmental pollution and other ecological environments are seriously deteriorating, and special living micro-environments such as confined spaces have led to an urgent need for functional protective textiles. Taking antibacterial properties as an example, textiles are prone to breeding microorganisms. The microbial communities in nature are widely present in the surrounding environment, and can grow quickly once they encounter suitable humidity, nutrients and temperature. The microorganisms breeding on textiles not only affect the wearability of textiles, but also damage the health of users. Therefore, how to inhibit or kill microorganisms attached to textiles is an urgent problem in the textile industry. Antibac...
