A kind of high texture automobile interior material and preparation method thereof

Abstract

The invention relates to a high-texture automotive interior material and a preparation method thereof. The material is prepared from components in parts by weight as follows: 40-70 parts of polypropylene, 1-10 parts of a softening agent, 10-25 parts of a reinforcing agent, 2-5 parts of an accelerant, 5-20 parts of elastomers, 5-25 parts of mineral powder and 1-3 parts of a functional aid. Orientedfiber forming is realized with a strong shear and ultra-high-speed stretching method, the strength, rigidity, toughness and heat resistance of original polypropylene materials are substantially improved, the high-quality appearance product is obtained, good dispersion of the elastomers in a system is realized through high shearing dispersion, the surface of the obtained material touches soft andhas low gloss, the hard-plastic sense of the product is eliminated, the visual grade and the hand feeling comfortability of the automotive plastic interior are improved, and the most comfortable interior space is created.

Description

technical field [0001] The invention relates to a car interior material and a preparation method thereof, in particular to a high-quality car interior material and a preparation method thereof, belonging to the field of material technology. Background technique [0002] With the improvement of people's living standards, people's requirements for vehicle performance are getting higher and higher not only in terms of power, economy, and safety, but also in terms of vehicle comfort. A comfortable driving environment has gradually become an important symbol of modern cars. Among them, car interior parts are the first parts that people see and feel when they enter the car, and its grade level is a very important part of the comfort of the whole car. At present, most middle and low-end car interior parts are mainly made of hard plastic injection molding, giving people a low-end feeling. In order to improve the comfort level of visible interior parts, OEMs mainly use skinning or ...

AI Technical Summary

Problems solved by technology

[0003] In recent years, people have also carried out some attempts to develop, for example, in order to ensure the rigidity of parts on the premise of realizing the soft appearance of parts, glass fibers are often directly introduced into polypropylene materials with high rubber content, although this plays an important role. Skeleton supports to achieve rigidity. However, the introduction of glass fiber will cause problems such as floating fibers on the surface of the parts during the material injection molding process, and will also cause the surface of the parts to be very rough, which cannot meet the requirements of automotive interior parts.
