Abstract

The invention discloses a high-strength antibacterial plastic and a preparation method thereof. The preparation method comprises the following steps: (1) mixing silicon dioxide, asbestos, kaolin, zinc borate, Chinese herbal medicines and water for decocting, and then, filtering a filter cake to prepare an anti-bacterial activator; and 2) mixing polyvinyl chloride, ethylene-ethyl acrylate copolymer, polyimide, tri(2,4-ditert-butyl phenyl) phosphite ester, laurel amide ethyl sodium sulfate, a carbon nano tube, zirconium phosphate, bamboo leaf phenolic ketone, wollastonite fibers, vinyl trimethoxy silane and the anti-bacterial activator to obtain a mixture, and processing and forming the mixture to prepare the high-strength antibacterial plastic. The Chinese herbal medicines contain sea-buckthorn, mulberry twigs, ligusticum sinense oliver, arisaema consanguineum schott, radix bupleuri, phellodendri, cyrtomium fortune, nandina roots, cortex acanthopanacis, schisandra chinensis, jiuliming, licorice section and semen strychni. The plastic prepared by the method has excellent antibacterial characteristics and mechanical strength; and meanwhile, the raw materials are easily available, and the process is simple.

Description

technical field [0001] The invention relates to plastics, in particular to a high-strength antibacterial 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....
