Abstract

The invention discloses a polypropylene composite material and a preparation method and application thereof, and belongs to the field of composite materials and electric heating. The polypropylene composite material is prepared from the following components: polypropylene, a toughening agent, a compatibilizer, conductive filler, a flame retardant, an antioxidant, a heat stabilizer, a lubricant andwhite oil, wherein the compatibilizer is polypropylene grafting maleic anhydride and / or polypropylene grafting glycidyl methacrylate, and the heat stabilizer is lanthanum stearate and / or isooctyl tindimethylmercaptoacetate. According to the polypropylene composite material and the preparation method and application thereof, a polypropylene material is used as matrix resin, and compounded with the conductive filler, the compatibilizer, the heat stabilizer, the antioxidant and other auxiliaries, so that the polypropylene composite material which can be used for heating under safe voltages is produced, the polypropylene composite material can quickly rise to the set temperature after power on, and has the advantages of high mechanical strength, high flame retardancy and the like.

Description

technical field [0001] The invention relates to the field of composite materials and electric heating, in particular to a polypropylene-based composite material and its preparation method and application. Background technique [0002] At present, electric heating coils on the market are often made of metal, and because they need to be energized at 220V to generate heat, there are many potential safety hazards. In addition, the fusing temperature of the metal wire is as high as 1000°C. When the solid-state contactor or thermostat in the product fails, the electric heating coil will continue to heat, so it is extremely easy to cause plastic shells, wood products, textile fibers and other items to burn, which may cause a fire. danger. [0003] In contrast, since the polypropylene resin softens at about 110°C, it can flow at about 150°C. When the temperature control of the circuit system fails, the polypropylene will continue to heat until the polypropylene melts and drops, so ...
