Abstract

The invention relates to a fiber-reinforced random copolymerization polypropylene composite pipe and a preparation method thereof. The fiber-reinforced random copolymerization polypropylene compositepipe is characterized in that the fiber-reinforced random copolymerization polypropylene composite pipe comprises an outer layer, an intermediate layer and an inner layer, the intermediate layer is arranged between the outer layer and the inner layer, a polyphenylene sulfide fiber reinforcing layer is arranged between the outer layer and the intermediate layer, and a basalt fiber pressure resistance layer is arranged between the intermediate layer and the inner layer. According to the fiber-reinforced random copolymerization polypropylene composite pipe, fiber-reinforced layer resin adopts toughened random copolymerization polypropylene to improve the low-temperature and impact resistance performance of the pipe; and the fiber-reinforced random copolymerization polypropylene composite pipecan be used for cold and hot water pipes, building main risers and other industrial pipes.

Description

【Technical field】 [0001] The present invention relates to the technical field of pipes, specifically a fiber-reinforced random copolymer polypropylene composite pipe and a preparation method thereof. 【Background technique】 [0002] Random copolymer polypropylene (PP-R) pipes are accepted by the market because of their good application characteristics such as hygiene, environmental protection, and reliable hot-melt connections. They are currently one of the most widely used types of building water supply pipe materials in my country. And deeply favored by domestic users. However, due to its large linear expansion coefficient in engineering applications, PP-R pipes are easily deformed when used in hot water systems; when simple PP-R pipes are used in main risers, their pressure resistance strength is slightly insufficient, etc., and many of the above defects This limits the further promotion and application of PP-R pipes in my country's building water supply market. Simply axi...
