Abstract

The invention discloses a mildew-resistant plastic and a preparation method thereof. The method comprises: 1) decocting after mixing silicon dioxide, asbestos, kaolin, zinc borate, Chinese herbal medicine and water, and then filtering to obtain a filter cake to obtain Antibacterial activator; 2) Polyvinyl chloride, ethylene-ethyl acrylate copolymer, polyimide, three (2,4-di-tert-butylphenyl) phosphite, sodium lauramide ethyl sulfate, carbon nano tube, zirconium phosphate, bamboo leaf ketone, wollastonite fiber, vinyltrimethoxysilane and antibacterial activator are mixed, and then processed to make anti-mildew plastic; , Huoxiang, Chunpi, Guanzhong, Sanchaku, Chuantongpi, Schisandra, Jiuliming, Shanjiao and Horse Qianzi. The plastic prepared by the method has excellent antibacterial properties and mechanical strength, and at the same time, the raw material of the method is easy to obtain and the process is simple.

Description

technical field [0001] The invention relates to plastics, in particular to a mildew-resistant plastic and a preparation method thereof. Background technique [0002] Plastic is a high molecular compound polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It is commonly known as plastic or resin. It can freely change its composition and shape. , Colorants and other additives. The main component of plastic is resin. The term resin was originally named after the lipids secreted by animals and plants, such as rosin, shellac, etc. Resin refers to a polymer compound that has not been mixed with various additives. Resin accounts for about 40%-100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with no or few additives, such as plexiglass, polystyrene, etc. [0003] ...
