Abstract

The invention discloses a high-strength mildewproof plastic and a preparation method thereof. The method comprises the following steps: 1) mixing and then decocting silicon dioxide, asbestos, kaolin, zinc borate, Chinese herbal medicines and water and then filtering the decoction and taking a filter cake to prepare an antibacterial activator; 2) mixing polyvinyl chloride, ethylene-ethyl acrylate, polyimide, tris(2,4-di-tert-butylphenyl) phosphite, sodium lauroylamidoethyl sulfate, carbon nanotubes, zirconium phosphate, phenolic ketone of bamboo leaves, wollastonite fibers and vinyl trimethoxy silane with the antibacterial activator and then processing to prepare the high-strength mildewproof plastic, wherein the Chinese herbal medicines include herb of nutgrass galingale, rehmannia root, ligusticum sinense Oliv., hirsute shiny bugleweed herb, officinal magnolia bark, tree-of-heaven ailanthus bark, fineleaf schizonepeta herb, thin evodia twig and leaf, white mustard seed, Chinese magnoliavine fruit, climbing groundsel herb, ligustrum sinense and pericarp of pummelo. The plastic prepared by the method has excellent antibacterial characteristics and mechanical strength. Meanwhile, the method is accessible in raw materials and simple in processes.
