Modified PC/ABS alloy

Abstract

A modified PC / ABS alloy essentially consists of the following in mass fraction: 65 to 85 for PC / ABS, 10 to 20 for stiffening agent, 0.5 to 1 for coupling agent, 5 to 10 for bromide fire retardant, 1 to 3 for stibium fire retardant, 1 to 6 for plasticizer, and 0.2 to 0.5 for oxidation inhibitor. By adding harden stiffening agent, plasticizer and fire retardant in the mixing process, the modified PC / ABS of the invention improves the surface hardness of the PC / ABS alloy as well as to further achieve the surface hardness and fire resistance and meets the technological requirement with little changing of the mechanical properties of PC / ABS, thus widening the application of PC / ABS alloy.

Description

technical field

[0001] The invention relates to the technical field of polymers, in particular to a PC / ABS alloy. Background technique

[0002] PC / ABS alloy resin is a kind of engineering plastic with better 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 ease of processing and low price of ABS resin. Advantages, good comprehensive performance, reasonable cost performance, and can be widely used in the automotive industry, household appliances and other fields.

[0003] When PC / ABS alloy is widely used in the panels of electronic and electrical products, in order to maintain the long-term aesthetic appearance and safety and fireproof performance, new requirements are put forward for its 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 increases the cost b...
