Problems solved by technology

But on the one hand, PP has poor impact resistance and cannot meet the requirements of the mechanical strength of car seats in contemporary society. On the other hand, PP has poor cold resistance and weather resistance, and insufficient rigidity at high temperatures.
However, when affected by light, cold and heat, wind and rain, etc., the car seats produced by PP will show aging phenomena, such as yellowing, tarnish, surface cracks, and significant decline in mechanical properties, resulting in a short service life of the car seats.

Abstract

The invention relates to the field of plastic raw materials, in particular to a basalt fiber-reinforced high-weather-resistance PP composite and a preparation method thereof. The basalt fiber-reinforced high-weather-resistance PP composite is prepared from, by weight, 60-80 parts of PP, 12-20 parts of basalt fiber, 3-6 parts of a main antioxidant, 1-3 parts of an auxiliary antioxidant, 1-4 parts of a coupling agent, 1-4 parts of a compatilizer, 2-5 parts of a flame retardant, 1-3 parts of a flame-retardant synergist, 0-2 parts of a light stabilizer, 0-2 parts of a heat-resistant agent and 0-2 parts of a plasticizer. The composite is high in mechanical strength, heat resistance, cold resistance and weather resistance, not prone to age and long in service life.

Description

technical field [0001] The invention relates to the field of plastic raw materials, in particular to a high weather resistance PP composite material reinforced by basalt fiber and a preparation method thereof. Background technique [0002] Polypropylene, abbreviated as PP, is another important plastic species after polyethylene (PE). It is a thermoplastic resin prepared by polymerization of propylene. It has excellent properties such as good electrical insulation and good transparency, and is widely used in industrial production, such as the automobile industry. [0003] In the automobile industry, modified polypropylene is often used in the processing of automobile seats, which has the advantages of good molding processability and light weight. But on the one hand, PP has poor impact resistance and cannot meet the requirements of the mechanical strength of car seats in contemporary society. On the other hand, PP has poor cold resistance and weather resistance, and insuffic...
