Abstract

The invention provides a bamboo charcoal and tourmaline composite Ag-loaded antibacterial agent, an antibacterial polypropylene composition and a preparation method. The bamboo charcoal and tourmaline composite Ag-loaded antibacterial agent is prepared from bamboo charcoal and tourmaline powder through Ag loading modification. The preparation method comprises the following steps that bamboo charcoal powder is loaded with Ag, tourmaline powder is loaded with Ag, and a bamboo charcoal powder Ag-loaded antibacterial agent and a tourmaline powder Ag-loaded antibacterial agent are mixed according to the ratio of (1-3): 1. The prepared composite antibacterial agent is added into a polypropylene composition, and through the mutual auxiliary effect of Ag, bamboo charcoal and tourmaline, multiple antibacterial modes such as silver ion slow release, bamboo charcoal adsorption and negative ion sterilization are achieved, and the efficient and lasting antibacterial effect on common bacteria such as escherichia coli and staphylococcus aureus is achieved.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a bamboo charcoal tourmaline composite powder loaded with Ag antibacterial polypropylene composition for automobile interior decoration and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards and the development of science and technology, the number of cars has continued to increase. People's health and hygiene awareness has continued to increase while cars have become popular. The security situation is more concerned. The interior of the car is in a relatively closed environment, which is a breeding ground for various bacteria, molds and other viruses; in addition, dust, human sweat, sebum, grease, soot and other substances as well as external dirt are also very easy to adhere to the car interior materials In fact, these pollutants will produce lower fatty acids (such as pelargonic acid, capr...
