Problems solved by technology

In the past, the method of surface spraying was used to improve the surface hardness, but surface spraying not only increases the cost but also puts a certain pressure on environmental protection. Therefore, it is very important to research and develop high-hardness flame-retardant PC / ABS alloys.

Abstract

The invention discloses a modified high hardness flame-retardant poly carbonate (PC) / acrylonitrile butadiene styrene (ABS) plastic alloy. The alloy is characterized by comprising the following substances in parts by weight: 30-40 parts of PC resin, 30-60 parts of ABS resin, 10-20 parts of organic solvent, 10-30 parts of concentrated hydrochloric acid, 20-23 parts of hardening agent, 10-20 parts of methyl phenyl siloxane branch type prepolymer, 10-15 parts of modifying agent, 10-35 parts of active calcium, 20-35 parts of stearic acid, 21-23 parts of lithopone, 1-3 parts of carbon black, 1-9 parts of nano calcium carbonate and 0.5-1 parts of dispersing agent. According to the modified PC / ABS alloy, the surface hardness of the PC / ABS alloy is improved, and the surface hardness and fire resistance of the PC / ABS alloy are improved on the basis of not greatly changing the mechanical property.

Description

technical field [0001] The invention relates to a modified high-hardness flame-retardant PC / ABS plastic alloy. Background technique [0002] PC / ABS resin is an engineering material with good comprehensive performance developed in the mid-1960s. It not only has the heat resistance, mechanical strength and dimensional stability of PC, but also has the advantages of easy processability and low price of ABS resin. , with good comprehensive performance and reasonable cost performance, it can be widely used in the fields of automobile industry, household appliances and so on. Since PC / ABS alloy is widely used in panels of electronic and electrical products, in order to maintain long-term aesthetic appearance and safety and fireproof performance, new requirements are put forward for surface hardness and flame retardancy. In the past, the method of surface spraying was used to improve the surface hardness, but the surface spraying not only increased the cost but also caused a certa...
