Composite material with flame-retardant function

Abstract

The invention discloses a composite material with flame-retardant function, which comprises the following components in parts by weight: 35-46 parts of propylene glycol monobutyl ether, 10-15 parts of n-propyl methacrylate, 3.5-9.5 parts of basic lead sulfite, 9-16 parts of 9,10-epoxy octyl stearate, 5-14 parts of silicon oil, 23-54 parts of ethylene copolymer elastomer, 15-21 parts of stearic acid, 35-67 parts of oxidized polyethylene ester, 3-6 parts of talcum powder, 18-36 parts of diisodecyl phthalate and 45-69 parts of acrylonitrile-styrene-butadiene copolymer. The composite material has the characteristics of flame retardancy and environmental protection, and is suitable for producing mechanical equipment, instruments, light equipment and other components.

Description

technical field [0001] The invention relates to a composite material with flame-retardant function. 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 literature, ...

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.
