Problems solved by technology

[0003] Automotive interior parts are mainly made of polypropylene material. Polypropylene has the advantages of small specific gravity, good heat resistance, low price, and easy processing and molding, but there are also disadvantages such as low strength, easy aging, flammability, and large molding shrinkage. Therefore, the modification of polypropylene to obtain higher performance is an important issue of research

Abstract

The invention discloses a toughened automobile interior composite material. The toughened automobile interior composite material comprising, by weight, 80 parts of homo-polypropylene, 20-30 parts of co-polypropylene, 15-25 parts of toughening agents, 5-10 parts of flame retardants, 3-5 parts of antioxidants and 1-2 parts of color batch, wherein the toughening agents are one or more of EPDM, EPR and SBS. According to the composite material, one or more of the EPDM, the EPR and the SBS are used as the toughening agents for blending modification of the polypropylene, and the shock strength of thepolypropylene can be improved; the effect is optimal when the mass ratio of the EPDM to the EPR is 1-3:1; and in addition, the proper flame retardants and the antioxidants are added so that the oxidation resistance and the flame retardancy of automobile interior products are improved.

Description

technical field [0001] The invention relates to automotive interior materials, in particular to a toughened automotive interior composite material. Background technique [0002] Automotive Interior mainly refers to the automotive products used in the interior modification of the car, involving all aspects of the car interior, such as car steering wheel covers, car seat cushions, car floor mats, car perfume, car pendants, armrests, interior ornaments, storage Boxes and so on are automotive interior products. [0003] Automotive interior parts are mainly made of polypropylene material. Polypropylene has the advantages of small specific gravity, good heat resistance, low price, and easy processing and molding, but there are also disadvantages such as low strength, easy aging, flammability, and large molding shrinkage. Therefore, the modification of polypropylene to obtain higher performance is an important issue of research. Contents of the invention [0004] Purpose of the...
