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 antibacterial masterbatch fiber preparation, in particular to a copper-based antibacterial masterbatch and a preparation method thereof. Background technique [0002] In today's society, the extreme environment, environmental pollution and other ecological environments have seriously deteriorated, and special living microenvironments such as confined spaces have led to an urgent need for functional protective textiles. Taking antimicrobial properties as an example, textiles are prone to the growth of microorganisms. Microbial communities in nature widely exist in the surrounding environment, and can multiply rapidly once encountering suitable humidity, nutrients and temperature. Microorganisms growing on textiles not only affect the performance of textiles, but also damage the health of users. Therefore, how to suppress or kill the microorganisms attached to textiles is an urgent problem to be solved in the texti...
