Light-weight scratch-resistant high-gloss material, preparation method of light-weight scratch-resistant high-gloss material, and application of light-weight scratch-resistant high-gloss material to preparation of automobile instrument panel

Abstract

The invention discloses a light-weight scratch-resistant high-gloss material, a preparation method of the light-weight scratch-resistant high-gloss material, and application of the light-weight scratch-resistant high-gloss material to the preparation of an automobile instrument panel. The light-weight scratch-resistant high-gloss material is prepared from the following ingredients in percentage by weight: 60 to 80 percent of homo-polypropylene, 5 to 20 percent of high-melt-strength polypropylene, 0.1 to 1.5 percent of nucleating agents, 0 to 5 percent of inorganic nanometer powder, 1.5 to 10 percent of polybutene, 5 to 15 percent of co-polypropylene, 0.1 to 2 percent of antioxidants and 0.1 to 2 percent of lubricating agents. The high-rigidity homo-polypropylene and the high-strength and high-heat-resistant high-melt-strength polypropylene is used to be compounded with the nucleating agent and the inorganic nanometer powder; under the condition of using a minute quantity of filling materials, the automobile instrument panel standard can be met; and the automobile light weight is realized. Meanwhile, the light-weight scratch-resistant high-gloss material has the characteristics of scratch resistance, high gloss, low smell and low VOC (volatile organic compounds) content; the instrument panel can be effectively protected; and the air quality in an automobile can be improved.

Description

technical field [0001] The invention relates to the technical field of polypropylene composite materials, in particular to a lightweight, scratch-resistant, high-gloss material, a preparation method thereof, and an application in the preparation of automotive interior dashboards. Background technique [0002] At present, light weight and environmental protection are the main directions of the development of automobile material technology in the world, reducing the weight of the automobile itself, thereby reducing automobile exhaust emissions, improving combustion efficiency and achieving energy conservation and environmental protection. With the large-scale development of electric vehicles, and the battery technology can not achieve a substantial breakthrough, the development of automotive lightweight technology is becoming increasingly urgent. As the instrument panel is one of the few large parts of polypropylene automotive materials, its lightweight is the trend of the time...

AI Technical Summary

Problems solved by technology

This technical solution uses amide lubricants to improve the scratch resistance of polypropylene materials. Although amide lubricants have special interface lubrication and excellent external lubrication effects, at present, the country has issued mandatory standards for automobile odor, and amide lubricants Lubricant-like lubricants have a strong smell and are obviously not suitable as lubricants for automotive interior materials

At the same time, the glossiness of commonly used inorganic powder-filled polypropylene automotive materials is greatly reduced, and some automobile OEMs have higher requirements for the glossiness of automotive parts, especially interior decoration.
