Environment-friendly flame-resistant ABS resin

Abstract

The invention discloses an environment-friendly flame-resistant ABS resin, which comprises the following components by weight percentage: 72 percent to 84 percent of ABS resin granules, 15 percent to 22 percent of PDSPB expanding type flame retardant, 0.7 percent to 4.5 percent of montmorillonite, 0.1 percent to 0.5 percent of anti-oxidant agent, 0.1 percent to 0.5 percent of anti-dripping agent and 0.1 percent to 0.5 percent of lubricant. The flame-resistant ABS resin does not contain harmful substances of lead, mercury, cadmium, hexavalent chrome, polybrominated biphenyls, polybrominated diphenyl ethers and the like, and meets the requirements of RoHS instruction about innocuity and environmental protection. The montmorillonite / PDSPB synergistic flame-resistant ABS resin not only can guarantee the flame-resistant performance, but also can keep good mechanical performance, can completely or partially replace the flame-resistant ABS resin of the traditional halogenated flame retardant and has wide market prospect.

Description

technical field [0001] The invention relates to the technical field of flame-retardant polymer materials, in particular to an environmentally friendly flame-retardant ABS resin. Background technique [0002] ABS resin is an acrylonitrile-styrene-butadiene copolymer, which has high impact strength, good processing performance and chemical stability, is easy to mold, and the product is glossy, and has both toughness and flexibility. Therefore, ABS resin is widely used in the automobile industry, electronic and electrical industry, light industrial appliances, textile and construction industries due to its excellent comprehensive performance, and has gradually become one of the most used thermoplastics. However, ABS resin is a kind of flammable polymer material. Its horizontal combustion speed is very fast, and a large amount of black smoke is produced when it is burned. It continues to burn after leaving the fire. It will bring great threat to people's life safety and living ...

AI Technical Summary

Problems solved by technology

Although the flame retardant effect of the traditional halogen-based flame-retardant system is good, it generates more smoke, corrosive gas and toxic gas during combustion. Therefore, the use of the traditional halogen-based flame-retardant system has potential harm to the environment and human body, and is not environmentally friendly. With the development of society, people's requirements for environmental protection and safety are increasing day by day, and the promulgation of the European Union's "RoHS Directive", the development of high-efficiency, lead-free, mercury-free, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers and other harmful substances, smoke generation Small, non-toxic and environmentally friendly flame-retardant ABS resin is of great significance and has a huge market space
