Abstract

The invention belongs to the field of functional plastic alloy materials, and particularly relates to an antistatic low-smoke halogen-free flame-retardant PC/ABS alloy material and a preparation process thereof. The alloy material comprises the following components in parts by weight: 60-85 parts of PC, 48-60 parts of ABS, 0.5-2 parts of a flame retardant, 0.5-2 parts of an antistatic agent, 1-4 parts of a compatibilizer, 0.5-1 part of a coupling agent, 0.5-1 part of a dispersant, and 0.5-1 part of an antioxidant. According to the alloy material and the preparation process disclosed by the invention, specific flame retardant compounding systems are added, so that the product achieves the effects of low smoke and flame retardance while having good mechanical properties.

Description

technical field [0001] The invention belongs to the field of functional plastic alloy materials, and in particular relates to an antistatic, low-smoke, halogen-free flame-retardant PC / ABS alloy material and a preparation process thereof. Background technique [0002] PC / ABS alloy is the earliest polycarbonate modified product to realize industrial production, and it is an important engineering plastic alloy. PC / ABS alloy has the advantages of both PC and ABS. On the one hand, the alloy can improve the heat resistance and tensile strength of ABS. On the other hand, it can also reduce the melt viscosity of PC and improve the processing performance. It can be used to form large-area and complex At the same time, it can reduce the internal stress of the product and improve the impact resistance at low temperature. PC / ABS alloy materials have been widely used in the automobile industry, and are the most suitable interior materials for automobiles, especially for instrument panel...
