Problems solved by technology

Although there are many manufacturers of polypropylene materials in China, due to the imperfect material formula and processing technology, the polypropylene materials produced by domestic manufacturers are far inferior to similar foreign materials in terms of mechanical properties and thermal oxidation resistance; while foreign imports The polypropylene material, although its performance has been further improved after modification, but its price is expensive, which will inevitably increase the production cost

Abstract

A polypropylene modified material and the preparation method thereof belong to the technical field of organic materials. The material comprises propylene copolymer, homogeneous polypropylene, talcum powder, chemical inhibitor, metal deactivator, nucleating agent, resin acceptor and calcium stearate. The preparation method thereof comprises that the resin acceptor is used for treating the talcum powder; the propylene copolymer, the homogeneous polypropylene, the talcum powder, the chemical inhibitor, the metal deactivator, the nucleating agent, and the calcium stearate are added into a high-mixing barrel, fully blended, and then blended and melt with a double screw machine, and finally braced and granulated. The preparation method has reasonable design, simple operation, and low cost. The invention not only maintains the original advantages of the polypropylene material, but also has good mechanical property, heat oxidation resistant performance and heat oxidation resistant performanceafter high temperature resistant scour. The performances of the polypropylene modified material surpass the performances of the existing polypropylene modified material at home and abroad. And the polypropylene modified material has low production cost and low price.

Description

technical field [0001] The invention belongs to the technical field of organic materials, and in particular relates to a modified polypropylene material and a production method thereof. Background technique [0002] As a general-purpose plastic, polypropylene has the advantages of excellent processing performance, good mechanical properties, and corrosion resistance, so it occupies an important position in plastics. However, when polypropylene is used in some parts, its strength, heat resistance, etc. Far from meeting the requirements. For example, some washing machines that appear on the market now have high-temperature washing, sterilization and drying functions, which makes the materials of the resin structural parts of the washing machine have strong mechanical properties, thermal oxidation resistance and thermal oxidation resistance after high-temperature washing. Although there are many manufacturers of polypropylene materials in China, due to the imperfect material f...
