▎ 摘　　要

NOVELTY - Antiviral PU protective clothing is made of modified PU, where the modified PU surface is provided with a bactericide, and the bactericide comprises nano-silver, nano-zinc oxide, nano-copper sulphate, nano-silicon dioxide, and auxiliary agent. USE - Antiviral PU protective clothing. ADVANTAGE - The antiviral PU protective clothing has good antibacterial effect, where nano-silver is a very common nano bactericide, fine nano zinc oxide particles, can be firmly adhered together therefore when the sterilizing agent is sprayed on the surface of the clothes, it can form a layer of antibacterial protective film on the surface and stable performance, it can be cleaned multiple times in high temperature water, the other copper ion is also a good bactericide and nano silicon dioxide because of its microstructure can effectively bond, the other substances together also can improve the service life of the whole because it has a certain anti-ultraviolet oxidation resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing anti-virus PU protective clothing, which comprises: a. mixing the graphene powder with distilled water gradually: b. adding aluminium sulphate solution: c. stirring for 1-2 hours; d. filtering the precipitate and drying, adding polyethylene glycol electrolyte powder into the precipitate, and after drying stirring and washing filtering the precipitate to obtain precipitate; e.uniformly mixing the precipitate A with the polyether polyol dibutyltin dilaurate and dimethylformamide; f. stirring and heating to obtain the polyurethane resin; g. atomizing and spraying the sterilizing agent in the polyurethane resin to form the antibacterial polyurethane resin; h. soaking into dimethyl formamide solution to solidify at last taking out and orderly washing and drying; i. uniformly paving the nano-silver on the PU leather surface after forming, coating the antibacterial polyurethane resin brush on the surface: j. soaking into dimethylformamide solution to solidify finally taking out and washing by water drying to obtain the PU leather. h. taking the PU leather forming base material plate uniformly, and: i. coating the antibacterial polyurethane resin.
