Abstract

The invention discloses a low-heat-storage-degree polypropylene composite material for automotive upholstery and a preparation method thereof. The material comprises the following raw materials: 55-75parts of polypropylene, 5-15 parts of polyolefin elastomer, 10-20 parts of talcum powder, 3-10 parts of infrared reflection filler A, 3-10 parts of infrared reflection filler B, 0.6-1.0 part of antioxidant, 0.3-0.5 part of dispersing agent, 0.5-3 parts of deodorant, 0.3-3 parts of scratch-resistant agent, 0.5-2 parts of stabilizer and 1-3 parts of infrared reflection pigment. The invention also provides the preparation method of the polypropylene composite material. The infrared reflection filler A, the infrared reflection filler B and the infrared reflection pigment are compatible with polypropylene, the blending effect is good, reflection of the polypropylene composite material to visible light, infrared light and ultraviolet light radiation energy is improved, the capacity of absorbingillumination radiation energy is reduced, the temperature in an automobile is reduced, and the comfort of passengers is improved.

Description

technical field [0001] The invention belongs to the technical field of polypropylene materials, in particular to a low heat storage polypropylene composite material for automobile interior parts and a preparation method thereof. Background technique [0002] With the increasing development of the automobile industry and the continuous improvement of consumers' awareness of comfort, health, and safety, people not only require cars to have good driving performance, excellent safety, and spacious interior space, but also require a comfortable interior temperature. , The air quality is good, which is beneficial to human health. In today's cars, the car owners are most disgusted by the high temperature in the car, especially in summer, the high temperature not only makes the passengers feel extremely uncomfortable, but also causes the car interior parts to emit a lot of harmful gases and unpleasant odors, affecting the passenger. the health of the driver. [0003] At present, t...
