Antibacterial modified PP high polymer material and preparation method thereof

Abstract

The invention discloses an antibacterial modified PP high polymer material and a preparation method thereof, and belongs to the technical field of composite materials. The antibacterial modified PP polymer material is prepared from the following components: co-polypropylene, homo-polypropylene, polyoxyethylene, superfine talcum powder, light calcium carbonate, aluminum hydroxide, zinc stearate, titanate, nano-silver master batch, silicone powder, white mineral oil, oxidized polyethlene wax, tetra[beta-(3, 5-di-tert-butyl-4-hydroxyphenyl) propionic acid] pentaerythritol ester, tri[2, 4-di-tert-butylphenyl] phosphite ester and 2-hydroxy-4-n-octyloxybenzophenone. The plastic material disclosed by the invention is high in surface strength, good in tensile resistance, acid and alkali corrosion resistance, good in water resistance and antibacterial property, and can be used for a front-end module, a spare tire cabin, a battery box, a seat skeleton and the like in an automobile; The material is good in environmental protection property and light in weight, the air quality of the space in the automobile is improved, and light weight of the automobile is achieved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an antibacterial modified PP polymer material and a preparation method thereof. Background technique [0002] With the development of automobile lightweight requirements, the application of composite materials will become more and more extensive; the application direction of composite materials has also shifted from body outer coverings to some structural and functional parts, such as front-end modules, spare tire compartments, battery boxes , seat frame, etc., which put forward some new requirements for material strength and technology. [0003] Polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer, and it is one of the lightest varieties of all plastics. It is particularly stable to water, the water absorption rate in water is only 0.01%, and the molecular weight is about 80,000 to 150,000. Good formability, but due to large shri...
