Abstract

The invention discloses a heat-resistant antistatic composite functional material for an automobile roof. The functional material is prepared from the following raw materials in parts by weight: 30-45parts of modified polypropylene resin, 15-25 parts of ABS resin, 5-15 parts of silica fume, 8-12 parts of functionalized graphene powder, 1-3 parts of nano carbon sol, 2-3 parts of nano titanium dioxide, 1-2 parts of talcum powder, 2-3 parts of zirconium silicate, 0.5-1 part of zinc stearate, 3-8 parts of coconut fibers, 1-2 parts of a flexibilizer, 1-3 parts of a compatilizer, 0.5-1 part of an antioxidant and 1-2 parts of a flame retardant; the invention also discloses a preparation method of the composite functional material. Through the synergistic effect of the functionalized graphene, the nano carbon sol, the nano titanium dioxide, the talcum powder, the zirconium silicate and the zinc stearate, the material has good high temperature resistance and antistatic property, so that the phenomenon of static electricity in a vehicle is effectively reduced, dust deposition is also reduced, and the service life of the material is prolonged. Meanwhile, the riding comfort and safety are also improved.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and in particular relates to a heat-resistant and antistatic composite functional material for automobile ceilings and a preparation method thereof. Background technique [0002] The ceiling trim is an important part of the vehicle interior. Its main function is to improve the decoration of the car. At the same time, the ceiling trim can also improve the heat insulation and heat insulation effect between the inside and the outside of the car; reduce the noise inside the car, Improve the sound absorption effect; improve the comfort and safety of riding. Since the sun shines directly on the roof, the temperature on the top of the car is high, so the heat resistance and weather resistance indicators of the roof interior are more stringent. In addition, when people ride in a car, static electricity sometimes occurs, and the static electricity will make the surface of the material absorb ...
