Abstract

The invention discloses an antibacterial and low-odor decorative polypropylene material used in a saloon car and a preparation method thereof, wherein the material comprises the following components in percentage by weight: 60 to 80 percent of polypropylene, 1 to 20 percent of elastic body, 10 to 30 percent of talcum powder, 1 to 5 percent of photocatalytic micro-powder, 0.5 to 2.0 percent of antibacterial agent, and 0.3 to 1.0 percent of odor absorbent. The polypropylene material can keep low odor enduringly, has antibacterial and mould-proof functions, and has the advantages of strong bactericidal power, quick disinfectant effect, good durability, good stability, no secondary pollution and the like. According to the invention, odorous small molecules such as paraffin, olefins, arenes, amine, phenol, thiol, peroxide, aldehydes, ketones and the like can be effectively removed.

Description

technical field [0001] The invention relates to a modified polypropylene material, in particular to a polypropylene material for antibacterial and low-odor car interior decoration and a preparation method thereof. Background technique [0002] The interior parts of a car generally refer to the partitions of the car compartment, door trim panels, instrument panel assemblies, armrests, carpets and other components. In the past, materials such as metal, wood, and fiber textiles were mostly used for car interior parts, and the appearance and texture were not ideal. With the increasing awareness of environmental protection, some materials that can be recycled, have high material safety performance, and are easy to process are found to replace traditional materials. The materials have become the research and development content of the automobile manufacturing industry in various countries. At present, the interior parts of many cars have gradually used polypropylene (PP) material...
