Environment-friendly automotive interior composite material and preparation method thereof

Abstract

The invention discloses an environment-friendly automobile interior composite material. Characterized in that it is characterized in that it comprises, the composition comprises the following components in parts by weight: 30 to 40 parts of polypropylene resin; 2, 10-anthracene dicarboxylic acid/2, 10-anthracene dicarboxylic acid; 10 to 15 parts of 9,10-anthracenedicarboxylic/2,4-diamino-6-vinyl-S-triazine polycondensate, 20 to 30 parts of N-(4-cyano-3-trifluoromethylphenyl)methacrylamide-allylphenyl carbonate-triisopropanolate methacrylate copolymer, 10 to 15 parts of mullite fiber, 1 to 3 parts of initiator, 0.3 to 0.8 part of antioxidant, 0.5 to 1.5 parts of compatilizer and 2 to 5 parts of nano porous hollow cage-shaped titanium oxide. The invention also provides a preparation method of the environment-friendly automotive interior composite material. The environment-friendly automobile interior composite material disclosed by the invention is excellent in mechanical property, smallin pungent smell, good in flame retardance and impact resistance, excellent in wear resistance, thermal stability, aging resistance, low temperature resistance and scratch resistance, good in comprehensive performance and long in service life.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an environment-friendly automotive interior composite material and a preparation method thereof. Background technique [0002] In recent years, with the progress of the society and the development of the economy, people's living standards have been improved year by year. Cars have gradually become popular in ordinary income families and have become one of the main means of transportation for people's daily life. Automotive interior materials are an important part of a car and refer to the materials used inside the car, including single materials or laminated composite materials used in car interior decoration, such as seat cushions, seat backs, seat covers, seat belts, headrests , armrests, retractable roof, all decorative linings (including door inner panels, side panels, headliner), instrument panels, glove boxes, interior shelf panels or rear sill panels, curtains,...

AI Technical Summary

Problems solved by technology

However, the existing polypropylene plastic smell has a strong pungent smell, which is unbearable, and it will also cause harm to human health if it is in this environment for a long time

In addition, this kind of material also has problems such as low strength, easy aging, flammability, and large molding shrinkage.

There are also other types of automotive interior materials on the market, but they generally have poor wear resistance and flame retardancy, which will increase the VOC content in the car, which is not conducive to the health of passengers in the car
