Polymer nano ZnO compound antibacterial agent for synthetic leathers based on in-situ polymerization process and preparation method of polymer nano ZnO compound antibacterial agent



The invention relates to a polymer nano ZnO compound antibacterial agent for synthetic leathers based on an in-situ polymerization process and a preparation method of the polymer nano ZnO compound antibacterial agent. Studies relative to an antibacterial agent for synthetic leather base cloths have been rarely reported at present. The preparation method comprises the following steps: mixing zinc acetate and ethanol in water bath, and adding diethanolamine and diallyldimethylammonium chloride to prepare a nano ZnO sol; uniformly mixing allyl glycidyl ether, methacrylic acid and the nano ZnO sol to prepare a nano ZnO sol mixed solution; and mixing diallyldimethylammonium chloride, an ammonium persulfate aqueous solution and a sodium hydrogen sulfite aqueous solution in the water bath for bottoming, dropwise adding the ammonium persulfate aqueous solution and the nano ZnO sol mixed solution, performing stirring reaction, and performing heat preservation and cooling to obtain the antibacterial agent for superfine fiber synthetic leather base cloths. According to the compound antibacterial agent disclosed by the invention, the antibacterial properties of the synthetic leather base cloths can be well improved by virtue of the synergistic effects of N<+> and nano ZnO; and the compound antibacterial agent can be applied to the superfine fiber synthetic leather base cloths, and ensures that the antibacterial rate on escherichia coli and staphylococcus aureus can reach more than 99%.
