Problems solved by technology

In particular, some ordinary polypropylene filled modified materials have disadvantages such as poor strength and strong odor, and may be deformed under the action of external force, resulting in damage to the product, which in turn limits the high requirements of polypropylene in terms of strength and odor. use of
[0004] In order to solve this problem, high-strength, low-odor polypropylene is usually selected to improve its strength and odor. However, when traditional polypropylene is prepared, due to different preparation methods, some small molecules will remain inside some polypropylene. It will be released at high temperature and affect the air quality in the car. Therefore, it is an urgent problem to propose a high-rigidity, low-emission composite polypropylene material for vehicle interiors.

Abstract

The invention relates to the technical field of high polymer material modification, in particular to high-rigidity and low-emission composite polypropylene for vehicle interiors and a preparation method of the high-rigidity and low-emission composite polypropylene for the vehicle interiors, and the high-rigidity and low-emission composite polypropylene comprises the following components in parts by weight: 50-65 parts of low-odor polypropylene resin; 15 to 20 parts of mineral filler; 0.2 to 0.8 part of an antioxidant; 0.5 to 2.0 parts of a lubricant; 0.2 to 0.8 part of a light stabilizer; 1-3 parts of a nucleating agent; the low-odor polypropylene resin is prepared by blending homo-polypropylene resin and co-polypropylene resin according to a ratio of 2: 1. By adding the nucleating agent into the polypropylene, the strength of the polypropylene material is improved, the crystallinity of the polypropylene composite material is improved, and the content of micromolecular volatile substances in a crystalline region is lower than that in a non-crystalline region, so that the content of the micromolecular volatile substances in the polypropylene composite material is reduced; and the odor and VOC are not increased after being heated and melted again.

Description

technical field [0001] The invention relates to the technical field of polymer material modification, in particular to a high-rigidity and low-emission vehicle interior composite polypropylene and a preparation method thereof. Background technique [0002] Polypropylene is a thermoplastic resin obtained by polymerizing propylene. It is a non-toxic, odorless and tasteless milky white high crystalline polymer. Due to its advantages of low cost, light weight, excellent processing performance and convenient recycling, polypropylene is widely used in automobiles, home appliances and other fields with the rapid development of science and technology today, especially automobile interior and exterior trim parts, such as door trim panels, Dashboards, pillars, seat guards, bumpers, side surrounds, air deflectors, fenders, etc. [0003] With the increasing development of the automobile industry and the continuous improvement of consumers' awareness of environmental protection, in add...
