Abstract

The invention belongs to the technical field of modified plastics, and particularly relates to a high-ball-pressure flame-retardant PC / ABS (polycarbonate / acrylonitrile-butadiene-styrene) material as well as a preparation method and application thereof. The material is mainly prepared from the components such as the polymeric high-molecular flame retardant, the antimony flame retardant, the heat-resistant agent and the organic silicon / acrylic acid composite rubber flexibilizer, all the components have a synergistic effect, the polymeric high-molecular flame retardant and the heat-resistant agent can jointly increase the ball pressure temperature of the ABS material, the toughness of the ABS material can be improved by combining with the flexibilizer, and the toughness of the ABS material is improved. The high ball pressure temperature of the flame-retardant PC / ABS material is remarkably improved, meanwhile, the flame retardance and the mechanical property of the flame-retardant PC / ABS material can be guaranteed, and the flame-retardant PC / ABS material is very suitable for manufacturing high-temperature-resistant products.

Description

technical field [0001] The invention belongs to the technical field of modified plastics. More specifically, it relates to a high ball pressure flame-retardant PC / ABS material and its preparation method and application. Background technique [0002] Acrylonitrile-butadiene-styrene terpolymer (ABS), a material with both rigidity and toughness, is widely used in home appliances, office equipment and automobiles. At the same time, ABS is also a flammable material, and its heat resistance and flame retardancy are not very good. It needs to be transformed into a flame retardant material by adding a flame retardant. Since low-molecular bromine, phosphorus and nitrogen flame retardants have certain plasticizing properties for ABS resins, adding them will lead to a significant reduction in the heat resistance of ABS materials. For example, the ball pressure (heat resistance) of general ABS materials is only about 85°C, and the ball pressure temperature is lower after adding flame ...
