Abstract

The invention relates to an antibacterial AES composite material and a preparation method thereof. The antibacterial AES composite material is prepared from the following components in parts by weight: 90 to 120 parts of AES, 2 to 4 parts of antibacterial agent, 5 to 8 parts of nano medical stone, 10 to 16 parts of wollastonite fibers, 0.1 to 0.5part of antioxidant, and 0.1 to 0.3 part of lubricating agent. The nano medical stone has the antibacterial property; and the nano medical stone and the antibacterial agent NOVARON AGZ300 can collectively improve the antibacterial performance of the AES composite material, so that the addition amount of the antibacterial NOVARON AGZ300 can be indirectly reduced.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to an antibacterial AES composite material and a preparation method thereof. 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...
