Abstract

The invention discloses a permanent antibiosis mildew-resistant nontoxicity and innocuousness polyester material and a preparation method thereof. According to the invention, polyester, a zeolite silver ion antiseptic, an air cleaning material by taking a titanium dioxide photocatalyst as a basic material, an anti-oxidant, an ultraviolet-resistant auxiliary agent, and a dispersant are mixed to prepare the material; wherein the dispersant is active siloxane powder of an American Dow Corning company, and a model is RM4-7051. The preparation method employs novel active siloxane powder as a dispersant, the antibiosis powder is easily enriched at the surface of a carrier, the antibiosis powder is firmly controlled in the carrier resin without migration, long-term biological security and stability can be kept, a contact area of the antiseptic and microbe can be greatly enhanced, and the antibiosis deodorizing efficiency of the antiseptic and the permanence of the antiseptic in the carrier resin can be enhanced. The material has higher antibiosis efficiency and biological safety, better processing performance, smooth surface, excellent mechanical properties, and nontoxicity and innocuousness.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a permanent antibacterial, mildewproof, nontoxic and harmless polyester material and a preparation method thereof. Background technique [0002] With the continuous improvement of the economy and living standards, people will pay more and more attention to their own health. Many articles in daily life contain a large number of microorganisms, and various pathogenic microorganisms that are contaminated or bred on the products we come into contact with every day are threatening our health all the time and hiding unexpected hazards. According to the statistics of the World Health Organization (WHO) in 1998, the annual death toll in the world is about 52 million, of which the number of deaths caused by microorganism-related diseases accounts for about 33%. In 1996, a food poisoning incident of native Escherichia coli O-157 occurred in Japan, which caused panic all over...
