Flame-retardant ABS (acrylonitrile-butadiene-styrene) plastic

Abstract

The invention discloses a flame-retardant ABS (acrylonitrile-butadiene-styrene) plastic which is prepared from the following raw materials in parts by weight: 40-50 parts of acrylonitrile, 40-50 parts of butadiene, 40-50 parts of styrene, 8-10 parts of alkyl benzene sulfonate, 5-8 parts of polycarbonate, 0.5-1 part of metastannic acid, 1-3 parts of stearic acid, 0.05-0.1 part of aluminum hydroxide, 0.5-1 part of zirconium oxide, 2-5 parts of aluminum hypophosphite, 1-3 parts of ammonium polyphosphate, 2-5 parts of mica, 5-8 parts of glass fiber and 1-3 parts of coupling agent. The flame-retardant ABS plastic has the advantages of favorable flame retardancy, excellent comprehensive physical and mechanical properties, excellent low-temperature impact resistance, favorable heat resistance and favorable electric properties.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a flame-retardant ABS plastic. Background technique [0002] ABS plastic has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the characteristics of easy processing, stable product size and good surface gloss. It is easy to paint and color, and can also be sprayed on the surface. Secondary processing such as metal plating, electroplating, welding, hot pressing, and bonding are widely used in industrial fields such as machinery, automobiles, electronic appliances, instrumentation, textiles, and construction. It is a thermoplastic engineering plastic with a wide range of uses. However, ABS plastic has a low heat distortion temperature, is flammable, and has poor weather resistance. Most of the modified ABS materials are mixed with nozzle materials and recycled materials, resulting in ...

AI Technical Summary

Problems solved by technology

However, ABS plastic has a low thermal deformation temperature, is flammable, and has poor weather resistance. The melting temperature is 217~237°C, and the thermal decomposition temperature is above 250°C. The materials for the housing of household appliances and office automation equipment have flame retardant requirements. Today's market Most of the modified ABS materials are mixed with nozzle materials and recycled materials, resulting in different performance and instability of molded products.
