Problems solved by technology

The resin and additives of water paint are almost all dispersed in water, prepared into slurry, and then coated. In order to ensure the uniformity and adequacy of mixing, N-ethylpyrrolidone, which is commonly used in this field, is used as an excellent cosolvent in the water. Adding it to the slurry of the water paint layer can increase the solubility on the one hand, and ensure the product stability of the automotive interior leather on the other hand.

Abstract

The present invention discloses a reproductive-toxicity-free polyvinyl chloride vehicle interior decoration leather and a preparation method thereof, wherein the reproductive-toxicity-free polyvinyl chloride vehicle interior decoration leather comprises a polyvinyl chloride surface layer, a polyvinyl chloride foaming layer and an aqueous paint layer coated on the polyvinyl chloride surface layer. According to the present invention, the aqueous paint layer does not contain N-methylpyrrolidone and N-ethylpyrrolidone, and does not have reproductive toxicity under the premise of the meeting of the environmental protection requirements of low VOC and low odor, and the surface performance requirements of wear resistance, illumination resistance, heat resistance, fouling resistance and the like so as to avoid the harm to human body.

Description

technical field [0001] The invention relates to the field of leather, in particular to a polyvinyl chloride automotive interior leather without reproductive toxicity and a preparation method thereof. Background technique [0002] With the continuous development of the automobile industry, people's requirements for automobile environmental protection and safety continue to increase, and the requirements for the smell, VOC, and emission of automobile interior leather are becoming more and more stringent. OEMs have higher and higher environmental protection requirements for automobile interiors. . In automotive interiors, the paint layer on the surface needs to endow the interior leather with special functional requirements and environmental protection requirements: such as excellent wear resistance, scratch resistance, chemical solvent resistance and hand feeling, and low VOC, odor, emission, etc. Both the excellent characteristics of solvent paint and the environmental prote...
