HDPE/FF antibacterial composite material with ZnO-SiO2 and preparation method thereof

The invention relates to an HDPE/FF antibacterial composite material with silica-coated zinc oxide (ZnO-SiO2) based on acid protease treated chicken hair fibers (FF) and a preparation method thereof and relates to a surface antibacterial treatment method of regenerated natural fibers FF. The method comprises adding an antibacterial agent ZnO-SiO2, compounding modified natural fibers and a polymermaterial through melt blending, and adding an antibacterial agent into the high density polyethylene/chicken hair fiber (HDPE/FF) composite material. The modified HDPE/FF composite material retains the raw excellent characteristics of HDPE/FF, improves the antibacterial properties of the HDPE/FF composite material, prolongs the use period of the composite material, researches the non-isothermal crystallization kinetics and relaxation behavior of the HDPE/FF composite material and provides the theoretical basis for the production of protein-derived natural fiber/polymer composite material. 本发明涉及种在酸性蛋白酶处理鸡毛纤维(FF)的基础上添加二
