Problems solved by technology

However, the solvent-based adhesives used contain a large amount of volatile and harmful organic solvents, which escape during the production process and pollute the environment. If the solvents are not removed, the residues in the composite materials will also pollute the environment in which they are used.
In addition, in the prior art, the conventional automobile dashboard has a complex structure, and often adopts a spliced ​​structure. The dashboard has many curved surfaces and a large area. The processing technology of the dashboard is relatively high, especially the production cost is relatively high.
The power structure of an electric vehicle is different from that of a fuel vehicle, especially a miniature electric vehicle, which requires a low price. Therefore, the known instrument panel and its preparation method are not suitable for electric vehicles.

Abstract

The invention discloses a flame-retardant and environment-friendly material for electric automotive trims and a preparation method of the material. The material is prepared from 200-350 parts of polypropylene resin, 80-150 parts of filler, 6-12 parts of PE wax, 2-5 parts of maleic anhydride graft, 2-5 parts of a titanate coupling agent, 6-12 parts of an activator, 2-5 parts of ethylene bisoleamide, 12-25 parts of an expanding flame retardant, 6-15 parts of an external lubricant, 5-10 parts of an internal lubricant, 10-25 parts of a stabilizer and a proper amount of dye. The preparation method comprises the process of mixing at a high temperature, treating by stirring and extrusion molding. The flame-retardant and environment-friendly material is high in surface glossiness, non-tacky, attractive in appearance, firm and durable without deformation, good in quality product and wide in application range, and has bright development prospect.

Description

technical field [0001] The invention relates to the technical field of automotive interior parts, in particular to a flame-retardant and environment-friendly material for electric vehicle interiors and a preparation method thereof. Background technique [0002] Due to the rapid development of the world economy and the continuous improvement of people's living standards, the development of the automobile industry, especially the production of cars is changing with each passing day, and the models are constantly updated. The requirements for interior materials matching the models are also getting higher and higher. A single component material can no longer meet the requirements. In recent years, people usually use textile materials and other substrates to be processed into interior materials. In the process of composite processing, two or more substrates (such as textile materials + textile materials Or textile material + plastic + rubber) compounded by adhesive. However, th...
