AI Technical Summary

Problems solved by technology

Disadvantages: physical modification is used to improve the performance of polyvinyl chloride, no stable chemical structure is formed, and the mechanical properties are extremely unstable under high temperature conditions
Disadvantages: the reaction temperature is high, the degree of reaction is too intense, and the problems of material agglomeration and incomplete reaction are easy to occur, and the above researches have not solved the problem of sharp decrease in the mechanical properties of polyvinyl chloride materials under extreme conditions of high temperature and high humidity
Disadvantages: Nitriding layer is attached to the surface of the material treated with nitrogen as the plasma gas source, which is not conducive to the subsequent processing and molding of materials

Description

【Technical field】 [0001] The invention relates to the technical field of pipes, in particular to graphene-based high-performance polyvinyl chloride pipes and a preparation method thereof. 【Background technique】 [0002] Polyvinyl chloride resin is one of the five general-purpose plastic resins. It has been widely concerned and developed rapidly because of its advantages such as excellent performance, low price, and wide source of raw materials. The annual output and consumption of polyvinyl chloride rank second in the world. Compared with other polymer materials, polyvinyl chloride has electrical insulation, wear resistance, flame retardancy and chemical stability. Because polyvinyl chloride resin can produce various plastic products by adding additives or other methods during processing, it is widely used in fields such as construction, automobiles, cables and packaging materials. Both the production and consumption of PVC are growing rapidly, and this growth trend will co...
