Surface layer for automotive trim and preparation method thereof

Abstract

The invention provides a surface layer for automotive trim and a preparation method thereof. The surface layer for the automotive trim comprises a bottom layer and a trim layer. The bottom layer is connected with an automotive trim plate. The trim layer is installed on the bottom layer. The trim layer has a non-woven fabric layer and a carbon cloth adsorption layer. The non-woven fabric layer is exposed in air. The carbon cloth adsorption layer is installed between the non-woven fabric layer and the bottom layer. The advantage is that the preparation method for the surface layer for the automotive trim is capable of enabling current carbon powder to be prepared as the carbon cloth adsorption layer, and overcoming a defect that carbon powder particles are used as a structure for adsorbing apeculiar smell, and the surface layer is environment-friendly without volatilization of hazardous substances, and has excellent peculiar smell adsorption property and air purifying property.

Description

technical field [0001] The invention relates to the field of automobile decoration, in particular to a surface layer for automobile interior decoration and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, cars are gradually entering the lives of each of us, and we are likely to touch and use cars every day. Along with people's concern about their own health, the quality requirements, environmental protection and comfort requirements of automobile interiors have received more attention from most people. At present, automotive interior materials, seat lining leather covers, floor compartments, etc. are mainly made of non-woven fabric composite materials such as polyurethane and polyvinyl chloride, and these polyurethane composite materials are often used in the manufacturing process. More or less solvent-based production systems are used. The use of organic solvents not only pollutes the environment in production,...

Problems solved by technology

The use of organic solvents not only pollutes the environment during production, but also seriously damages people's health

For example, 1. A large amount of volatile substances such as solvents or glue or odorous chemicals such as ammonia are used in the production process; 2. The material itself volatilizes a large amount of gas when the production process is high temperature, which is harmful to human health; 3. In practice Affected by the long-term environmental temperature and humidity during use, the material decomposes slowly and volatilizes for 3 to 6 months, resulting in a heavy smell in the car for a long time, which has a great impact on people's use
