A kind of composition for preparing antibacterial composite material and preparation method of antibacterial composite material

Abstract

The invention provides a method for preparing an antibacterial composite material and a composition for preparing the antibacterial composite material. The method comprises the following steps that 1, a solution containing nano-silver material is used for conducting padding treatment on bamboo fiber filament, and a nano-silver-bamboo fiber composite fiber is obtained; 2, the nano-silver-bamboo fiber composite fiber makes contact with a coupling agent to conduct surface coating treatment after being subjected to short-cutting, and a surface modified nano-silver-short-cut bamboo fiber composite fiber is obtained; 3, acrylonitrile-butadiene-styrene copolymer and a chemical modifying agent and the nano-silver-short-cut bamboo fiber composite fiber are subjected to melting extrusion granulation, and the antibacterial composite material is obtained. The preparation method uses the bamboo fiber material and the nano-silver material simultaneously, the prepared antibacterial composite material has significant antibacterial and sterilizing effects; by using the coupling agent and the chemical modifying agent together and modifying the bottom fiber surface and a resin matrix simultaneously, the mechanical property of the antibacterial composite material is improved.

Description

technical field [0001] The present disclosure relates to the field of fiber composite materials, in particular, to a composition for preparing antibacterial composite materials and a preparation method of antibacterial composite materials. Background technique [0002] In recent years, the development of the automobile industry has brought great convenience to people. The emergence of new energy vehicles has further alleviated the current plight of resource shortage, and at the same time, the requirements for lightweight vehicles are increasing day by day. In response to the demand for lightweight vehicles, fiber-reinforced composite materials, as one of the main solutions, account for an increasing proportion of automotive materials. At present, fiber-reinforced composite materials are mainly composed of glass fibers, carbon fibers, etc. and plastics. The waste disposal is difficult and the production environment is harsh, which brings a great burden to the environment. As...
