Pollution-resistance high-temperature-resistance polypropylene material and preparation method thereof

Abstract

The invention belongs to the technical field of polymer composite material modification, and particularly relates to a pollution-resistance high-temperature-resistance polypropylene material and a preparation method thereof. The polypropylene material is characterized in that high-crystallization homopolymer polypropylene is taken as a basic component, polyketone resin is added to improve the wearresistance and mechanical performance of the material, barium sulfate masterbatch is taken as a filling agent to reduce dust pollution, a compatibilizer is added to improve the bonding force betweenraw materials to improve the mechanical performance of the material, organic group modified ultrahigh molecular weight polyorganosiloxane is taken as an antifouling agent to improve the water and oilresistance and the wear resistance of the material, and the anti-ageing performance of the material is improved by adopting an antioxidant. The material has the advantages of easy processing, high glossiness, high wearing resistance, pollution resistance, easy dyeing, excellent physical mechanical performance and the like, the demands by household electrical appliance products and kitchen electrical appliances on housing materials thereof in severe environments can be completely met, and the material can be widely applied to the production of plastic spare parts which need to slide or rotate in the fields of machinery, building materials, sports and the like.

Description

technical field [0001] The invention belongs to the technical field of modification of polymer composite materials, and in particular relates to an anti-pollution high wear-resistant polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a thermoplastic synthetic resin with excellent performance. It has many advantages such as high cost performance and convenient processing. It is widely used in the fields of automobiles and home appliances. Wear resistance and heat resistance need to be further improved according to its application environment. Especially when used in the fields of home appliances and daily necessities, PP materials have low hardness and poor surface wear resistance, which greatly reduces the aesthetics of the product; in addition, defects such as difficulty in cleaning the surface when it is contaminated with oil also lead to its application. Subject to certain restrictions. Usually, glass fiber, inor...

AI Technical Summary

Problems solved by technology

Especially when used in the fields of home appliances and daily necessities, PP materials have low hardness and poor surface wear resistance, which greatly reduces the aesthetics of the product; in addition, defects such as difficulty in cleaning the surface when it is contaminated with oil also lead to its application. subject to certain restrictions

Usually, glass fiber, inorganic filler, molybdenum disulfide, polytetrafluoroethylene and other fillers or additives are added in order to improve the wear resistance of PP materials, but these fillers or additives may introduce some other defects, such as gloss loss, product damage, etc. Warpage, cost increase, processing difficulties, etc.
