Polypropylene corrugated pipe composite material and preparation method of composite polypropylene corrugated pipe

Abstract

The invention discloses a polypropylene corrugated pipe composite material, which comprises the following raw material components in parts by mass: 50-70 parts of polypropylene, 10-20 parts of a butylbenzene transparent impact-resistant resin, 5-15 parts of ultra-high molecular weight polyethylene, 1-10 parts of a low-melting-point dispersing agent, 5-15 parts of a high-fluidity resin and 5-15 parts of a compatibilizer. According to the polypropylene corrugated pipe composite material provided by the technical scheme, the polypropylene corrugated pipe is prepared by compounding a plurality ofraw materials, so that the prepared polypropylene corrugated pipe has the characteristics of high strength, strong heat resistance and good low-temperature impact resistance at the same time. The invention further provides a preparation method of the composite polypropylene corrugated pipe prepared from the polypropylene corrugated pipe composite material, wherein the operability is high, and theprocessing fluidity and the compatibility during the preparation of composite polypropylene corrugated pipes can be improved.

Description

technical field [0001] The invention relates to the technical field of corrugated pipes, in particular to a polypropylene corrugated pipe composite material and a preparation method for a composite polypropylene corrugated pipe. Background technique [0002] my country is a big country in the production and consumption of plastic products, especially plastic pipes occupy an extremely important position in the development of the national economy. Plastic pipes are widely used in many industrial applications such as construction engineering, electric power engineering, municipal engineering, communication engineering and petrochemical engineering, and are closely related to people's lives. The development field of this industry is not limited to the manufacture of plastic pipes, but also derives from many related fields such as plastic material modification research, formula system design and engineering installation, forming a plastic pipe manufacturing based on new material ...

AI Technical Summary

Problems solved by technology

[0003] The current corrugated pipes for pipelines are generally produced by polyethylene, polyvinyl chloride or polypropylene. Polyethylene corrugated pipes have good impact resistance, but low softening temperature and low rigidity; PVC corrugated pipes have high rigidity, but there are The disadvantage of low temperature brittleness; polypropylene corrugated pipe has the advantages of light weight, high rigidity and high softening temperature, but it also has the disadvantage of insufficient low temperature impact performance
