[0013] The invention provides a kind of preparation method of high-strength antibacterial plastic, and this preparation method comprises:
[0014] 1) Mixing silicon dioxide, asbestos, kaolin, zinc borate, Chinese herbal medicine and water, decocting, and then filtering to take the filter cake to obtain antibacterial activators;
[0015] 2) Polyvinyl chloride, ethylene-ethyl acrylate copolymer, polyimide, tris (2,4-di-tert-butylphenyl) phosphite, sodium lauramide ethyl sulfate, carbon nanotubes, zirconium phosphate , bamboo leaf ketone, wollastonite fiber, vinyltrimethoxysilane and antibacterial activator are mixed, and then processed to make high-strength antibacterial plastic;
[0016] Among them, the Chinese herbal medicine contains seabuckthorn, shangzhi, haoben, nanxing, bupleurum, chuanbai, guanzhong, Tianzhugen, Wujiapi, schisandra, jiuliming, licorice festival, and saxoid.
[0017] In step 1) of the present invention, the consumption of each material can be selected in...
