Abstract

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.

Description

technical field

[0001] The invention belongs to the field of polymer composite materials, and relates to the improvement of the antibacterial performance of composite materials, which is to add ZnO-SiO to protein regenerated natural fibers / polymer composite materials 2 to enhance the antibacterial properties of the composites. Background technique

[0002] Fiber-reinforced polymer resin materials not only have the advantages of reinforcing fibers, but also have the properties of resins. The main features are: higher mechanical strength than ordinary resins, no common defects in natural fiber material products, a wide range of processing methods, green environmental protection and recyclable reuse etc.

[0003] Although the advantages of recycled natural fiber / polymer resin composites are many, the relevant research progress is still in the exploratory stage and immature, and there are some technical difficulties between natural fiber and polymer resin that need to be solved...
