Abstract

The invention belongs to the technical field of alloy materials and discloses a highly heat-resisting flame-retardant antistatic PC (polycarbonate) / ABS (Acrylonitrile Butadiene Styrene) alloy material and a preparation method thereof. The highly heat-resisting flame-retardant antistatic PC / ABS alloy material comprises the following components by weight part: 1 to 10 parts of ABS resin, 80 to 90 parts of PC resin, 7 to 10 parts of flame retardant, 1 to 10 parts of toughening agent, 0.02 to 0.5 part of antistatic agent, 0.1 to 1 part of photo-thermal stabilizing agent, and 0.1 to 1 part of processing assistants. The preparation method of the alloy material comprises the following steps:1 to 10 parts of ABS resin, 80 to 90 parts of PC resin, 0.02 to 0.5 part of antistatic agent, 7 to 10 parts of flame retardant, 1 to 10 part of toughening agent, 0.1 to 1 part of photo-thermal stabilizing agent, and 0.1 to 1 part of other processing assistants are sent into a double-screw extruder after being mixed, and then are subjected to compounding, extruding, strip drawing, cooling and palletizing, so as to obtain the finished product. The highly heat-resisting flame-retardant antistatic PC / ABS alloy material has the advantages that the process is simple and continuous, the production efficiency is high, and the product quality is stable.

Description

technical field

[0001] The invention belongs to the technical field of alloy materials, and in particular relates to a high heat-resistant, flame-retardant and antistatic PC / ABS alloy material and a preparation method thereof. Background technique

[0002] PC / ABS (a blend of polycarbonate and acrylonitrile-butadiene-styrene copolymer) resin is an alloy material with excellent performance, with excellent physical and mechanical properties, surface hardness, high strength and flow However, its disadvantage is that its flame retardancy is poor and it has high electrical insulation. Therefore, various modifiers are added to PC / ABS alloy to improve its performance. The high insulation of the polymer itself makes it difficult for static electricity to disappear from the charged plastic, which will cause dust to stick to the plastic product, electric shock to the user or operator of the product, abnormal operation of the counter or integrated circuit chip, etc. Therefore, it is ne...
