Abstract

The invention discloses a low smell and scratch resistant thin-wall material and a preparation method thereof. The low smell and scratch resistant thin-wall material is prepared from the following rawmaterials of, in parts by weight, 20-30 parts of homo-polypropylene, 45-55 parts of co-polypropylene, 10-15 parts of ultramicro fine talcum powder, 10-15 parts of flexibilizers, 0.2-0.6 part of an antioxidant, 2-5 parts of scratch resistant agents, 0.15-0.5 part of a lubricating agent, and 0.5-1.0 part of other assistants. The surface scratch resistance of the material can be improved, wall thinning of automobile parts can be achieved, and the material cost is lower.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a low-odor, scratch-resistant thin-walled material, and a preparation method for the low-odor, scratch-resistant thin-walled material. Background technique [0002] With the further improvement of the country's requirements for energy conservation and emission reduction and the rapid development of China's automobile industry, automobile lightweight has become an important way for automobile energy conservation and emission reduction and the main trend of automobile development. That is to reduce fuel consumption by reducing the weight of the body. According to the report of the World Aluminum Association: for every 10% reduction in the weight of the car itself, the fuel consumption of the car can be reduced by 6%-8%, and the emission can be reduced by 5%-6%. In order to achieve the goal of energy saving and emission reduction, under such a general trend, every part of the car ...
