Flame-retardant environment-friendly polycarbonate composite material

Abstract

The invention discloses a flame-retardant environment-friendly polycarbonate composite material. The composite material is characterized by comprising the following substances by weight: 35 to 64 parts of polybutylene telephthalate, 10 to 15 parts of propanediol butyl ether, 15 to 21 parts of polybutylene telephthalate, 45 to 52 parts of a polycarbonate resin, 10 to 14 parts of titanium dioxide, 5 to 9 parts of phosphate ester, 3 to 6 parts of diethyl maleate, 4 to 7 parts of diisodecyl phthalate, 11 to 17 parts of 9,10-octyl epoxy stearate, 15 to 20 parts of ascorbyl palmitate, 17 to 23 parts of fatty acid amide, 3 to 14 parts of decabromodiphenylethane, 5 to 7 parts of antimony trioxide and 3 to 5 parts of N-phenyl-N'-cyclohexyl-p- phenylenediamine. The polycarbonate composite material provided by the invention has the characteristics of flame retardation and environment friendliness and is applicable to production of parts of mechanical equipment, instruments, illumination equipment and the like.

Description

technical field [0001] The invention relates to a flame-retardant and environment-friendly polycarbonate 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 disc...

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.
