Abstract

The invention aims to provide an ABS antibacterial dedicated master batch, which is improved in antibacterial property, and a preparation method thereof. ABS (acrylonitrile / butadiene / styrene) copolymer is toxic-free and has excellent electric insulation performance, chemical performance, mechanical performance and processability, so that the ABS has highest consumption among the engineering plastics in our country and is applied widely in the fields of household appliances, traffic and transportation, building materials, medical appliances, stationery and sporting goods, daily products, etc. However, ABS plastic may be polluted by harmful microorganisms, which threatens health of human. A method of adding an antibacterial agent to ABS to produce antibacterial plastic herein is effective. The ABS antibacterial special master batch can overcome the defect that the ABS is liable to be polluted, and has significant meaning for application and further promotion of ABS material. The safety coefficient of the ABS during application in the household appliances, medical appliances, office supplies, etc.

Description

technical field [0001] The invention belongs to the technical field of ABS material production, and specifically relates to a special masterbatch for ABS which improves the original deficiencies of ABS and makes it have antibacterial properties and a preparation method thereof. Background technique [0002] ABS resin, English name: Acrylonitrile butadiene Styrene, abbreviated name ABS. The structural formula is as follows: [0003] [0004] ABS (acrylonitrile / butadiene / styrene) copolymer has become the engineering plastic with the largest consumption in my country due to its non-toxic, electrical insulation, chemical, mechanical and processing properties, and its application range includes household appliances. , transportation, building materials, medical equipment, cultural, educational and sporting goods, daily necessities and other fields. However, ABS plastic may be contaminated by harmful microorganisms, thus threatening people's health. It is an effective method ...
