Abstract

The invention discloses a composite antibacterial ABS material and a preparation method therefor. The composite antibacterial ABS material comprises the following ingredients in parts by weight: 100 parts of ABS, 0.3-1.2 parts of composite antibacterial agent, 1-5 parts of silane coupler, 0.2-1 part of dispersant, 1.5-2.5 parts of antioxidant and 0.5-2 parts of discoloration inhibitor. The composite antibacterial agent is prepared from the following ingredients in parts by weight: 40-60 parts of IONPURE silver-loaded antibacterial agent, 4-6 parts of chitosan, 20-40 parts of nano zinc oxide and 5-15 parts of photosensitizer CCA (chlorophyll cupric acid). Antibacterial ABS plastics disclosed by the invention are high in antibacterial performance and long in antibacterial effective period and have an obvious bacteriostasis effect on Staphylococcus aureus and Escherichia coli. The composite antibacterial ABS material has the advantages of easiness in processing, high antibacterial performance, difficulty in discoloration, excellent mechanical properties and the like.

Description

technical field [0001] The invention belongs to the technical field of new material preparation, and in particular relates to a preparation method of a composite antibacterial ABS material. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer is a terpolymer composed of acrylonitrile, butadiene and styrene. The English name is Acrylonitrile-Butadiene-Styrenecopolymer, referred to as ABS. Usually pale yellow or milky white granular non-crystalline resin. ABS resin has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It has the characteristics of easy processing, stable product size and good surface gloss. It is easy to paint and color, and can also be sprayed on the surface Secondary processing such as metal plating, electroplating, welding, hot pressing, and bonding are widely used in industrial fields such as machinery, automobiles, electronic appliances, instrumentation, textiles, ...
