Problems solved by technology

[0003] At present, the most common modification method in the market is to use PC/ABS alloy technology to increase the heat distortion temperature of flame-retardant ABS resin. Since the heat distortion temperature of PC resin itself is as high as 120°C or more, the addition of PC resin has a great impact on flame-retardant ABS resin. The heat resistance of the PC resin has been significantly improved, and because the PC resin itself has a high flame retardant performance, and the

Abstract

The invention discloses a heat resistant flame-proof ABS type resin and its preparing process, wherein the constituents include (by mass portions) ABS type resin 100 parts, flame retardant 2-30 parts, heat-proof modifier 5-20 parts, flexibilizer 1-10 parts, optical-thermal stabilizing agent 0.2-2 parts, and fabrication auxiliary agent 1-5 parts. The resin can substitute engineering plastics to be applied to situations for high requirement of flame-proof and heat resistance properties.

Description

technical field [0001] The invention relates to a heat-resistant and flame-retardant ABS resin and a preparation method thereof. Background technique [0002] ABS resin is a thermoplastic with excellent performance, which has high impact strength, heat resistance and dimensional stability. Due to its various advantages, it is widely used in industrial parts, housings and transmission parts of electronic and electrical products. Office equipment, and other fields. However, the flame retardancy of ABS resin itself is extremely low, the oxygen index is only about 18, and the vertical combustion test cannot meet the UL94V-2 standard. The flame retardant modification of the flame retardant is very important; because the heat resistance of the general-purpose ABS resin itself is not high, the general heat distortion temperature is about 82-84°C (ASTM D648, 1.82MPa), and the heat resistance temperature of the ABS resin after flame retardant modification Take the flame retardant A...
