Abstract

The invention provides an antibacterial slush molding skin for an automobile instrument panel and a preparation method and application of the antibacterial slush molding skin. The antibacterial slush molding skin is prepared from quaternary ammonium salt grafted polyvinyl chloride, and the quaternary ammonium salt grafted polyvinyl chloride is prepared from alkyl tertiary amine, a silane coupling agent and polyvinyl chloride; according to the antibacterial slush-molded skin for the automobile instrument panel, the quaternary ammonium salt is introduced to polyvinyl chloride to serve as an antibacterial chain segment, and a slush-molded forming process is matched, so that the antibacterial slush-molded skin with efficient antibacterial performance for the automobile instrument panel is successfully obtained, the mechanical property and the processing property of a product are not influenced, an original production process does not need to be adjusted during preparation, and the production cost is reduced. And the method has the advantage of high operability.

Description

technical field [0001] The invention belongs to the technical field of automobile materials, and in particular relates to an antibacterial slush plastic skin for an automobile instrument panel and a preparation method and application thereof. Background technique [0002] In recent years, more and more automobile instrument panel skins are prepared by powder slush molding technology. Polyvinyl chloride (PVC), as the world's largest general-purpose plastic, has the advantages of low price, stable chemical properties, good flame retardancy, excellent mechanical properties, and good electrical insulation. It is one of the most commonly used raw materials for automotive dashboard skins. . [0003] Antibacterial material refers to a new type of functional material that has the function of killing or inhibiting microorganisms. There are many substances in nature that have good bactericidal or microbe-inhibiting functions, such as some organic compounds with specific groups, some...
