Abstract

The invention relates to an antibacterial AES composite material. Specifically, the antibacterial AES composite material is composed of the following components by weight: 90-120 parts of AES; 5-10 parts of ABS; 2-4 parts of an antibacterial agent; 5-8 parts of nano medical stone; 10-16 parts of wollastonite fiber; 0.1-0.5 part of an antioxidant; and 0.1-0.3 part of a lubricant. Nano medical stoneitself has antibacterial properties, and can strengthen the antibacterial properties of the AES composite material together with the antibacterial agent NOVARON AGZ300, thus indirectly reducing the adding amount of the antibacterial agent NOVARON AGZ300.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to an antibacterial AES composite material. Background technique [0002] Acrylonitrile-EPDM rubber-styrene copolymer (AES) is an engineering plastic with excellent comprehensive properties. It has good dimensional stability, good insulation, oil resistance, and good molding performance. Although the overall performance of AES is excellent, in some special application fields, there are high requirements for antibacterial and mechanical properties, which cannot be met by ordinary AES, which greatly limits the application range of AES composite materials. [0003] The present invention creatively uses wollastonite fibers and antibacterial agents to modify AES to improve the mechanical properties and antibacterial properties of AES. The relevant literature has not been reported, which has very important practical significance for expanding the application range of AES composi...
