Flame-retardant and environment-friendly composite material

Abstract

The invention discloses a flame-retardant and environment-friendly composite material. The flame-retardant and environment-friendly composite material comprises the following substances in parts by weight: 55-70 parts of polycarbonate, 56-98 parts of crylonitrile-butadiene-styrene terpolymer, 35-64 parts of polybutylene terephthalate, 15-30 parts of poly alkylene glycol, 3-7 parts of N-ethyl-4-methylbenzenesulfonamide, 11-18 parts of pentaerythritol, 15-20 parts of magnesium hypophosphite, 12-32 parts of expansile graphite, 6-9 parts of antimonous oxide, 5-7 parts of expansile graphite, 20-30 parts of mercaptan and 5-7 parts of antimonous oxide. The flame-retardant and environment-friendly composite material disclosed by the invention has the characteristics of being flame-retardant and environment-friendly, and is applicable to producing mechanical equipment, instruments, illumination equipment and other components.

Description

technical field [0001] The invention relates to a flame-retardant and environment-friendly composite material. Background technique [0002] Polycarbonate (PC) is a thermoplastic with excellent performance. It is non-toxic, dimensionally stable, and high-strength. It is widely used in mechanical equipment, construction engineering, instrumentation, and lighting equipment. However, polycarbonate has the disadvantages of poor fluidity and difficult processing during processing. In order to improve processability, polycarbonate is compounded with some resins with good processability, which can significantly improve fluidity. Acrylonitrile-styrene-butadiene copolymer (ABS) has unique advantages of stress resistance, impact resistance and good processability, and is widely used in compounding with polycarbonate. However, in the production of flame-retardant products, it is still insufficient. In order to improve the flame retardancy, there are related schemes disclosed in the l...

Problems solved by technology

However, in the production of flame-retardant products, it is still insufficient. In order to improve the flame retardancy, there are related schemes disclosed in the literature, such as using antimonides to improve flame retardancy in CN100528961A. Due to the skyrocketing prices of antimonides such as antimony trioxide, and the existence of The risk of causing cell cancer has been listed as a restricted element by the European Union

Another example is the use of halogen-containing flame retardants in CN101759978A to improve the flame retardancy of polycarbonate. Halogen-based substances will release toxic gases when burned, which is not good for the environment and human development.
