Abstract

An ABS laser caving plastic having an antibiotic function comprises 75-85wt% of a transparent ABS resin, 5-10wt% of a PMMA resin, 3-8wt% of a PEG resin and 5-10wt% of a multifunctional color master batch. An antiseptic in the multifunctional black master batch forms an antibiotic system, and a complex antioxidant and PEG6000 together form a light and thermal stabilizing system, so the light degradation, photo-oxygen degradation and thermal oxygen degradation ageing of ABS can be effectively prevented, and requirements of the antibiotic performance and the laser caving performance of the ABS laser caving plastic are satisfied. The preparation method of the ABS laser caving plastic comprises a step of preparing the antibiotic laser caving multifunctional black master batch, and a step of preparing the ABS laser caving plastic having an antibiotic function through using the master batch. A multifunctional master batch technology provided in the invention eliminates the pollution of dusts to the environment, realizes the green and clean production of an ABS resin and an alloy, has the characteristics of less application amounts of carrier resins and a lubrication dispersant, low master batch processing energy and low processing assistant consumption amount, and can be widely used for the molding processing of ABS plastics.

Description

technical field [0001] The invention relates to the technical field of polymer plastics, in particular to an ABS radium sculpture material with antibacterial function and a preparation method. Background technique [0002] ABS resin obtained by terpolymerization of acrylonitrile, butadiene and styrene is widely used in the electronics and electrical industries for its excellent comprehensive properties. ABS radium sculpture materials occupy a large share in radium sculpture materials. Laser engraving (laser marking) has been successfully applied to computer keyboards, light switch covers, automotive interior buttons and door handles, instrument panels, rigid containers and container covers, electrical connectors, capacitors. The laser engraving of ABS plastic realizes the traditional printing process of ABS plastic, which is a new technology of energy saving and environmental protection in the electronic and electrical industry. [0003] With the improvement of people's liv...
