Abstract

The invention provides a polyethylene composite tubular product and a manufacturing method thereof and relates to the field of tubular products. According to the polyethylene composite tubular product, the problems that an existing PE tube is low in strength, has no flame retardance and low in low temperature resistance, and the maximum use pressure is limited are solved. The polyethylene composite tubular product contains the following components in parts by weight: 100-120 parts of polyethylene resin, 20-30 parts of SBS modified asphalt, 1-2 parts of light calcium carbonate, 3-5 parts of 1,2-dimethylimidazole, 5-10 parts of a nano-titanium dioxide / diatomite composite photocatalytic material, 4-12 parts of nano-zinc oxide, 3-6 parts of barium laurate, 5-15 parts of polytetrafluoroethylene, 7-13 parts of maleic anhydride grafted polyethylene, 15-25 parts of polyacrylate rubber, 2-5 parts of octabromo-ether, 2-4 parts of a color master batch and 3-8 parts of 4,4'-bis(alpha,alpha-dimethyl benzyl)diphenylamine. The polyethylene composite tubular product has good sealing property, flexibility, shock resistance, impact resistance, scraping resistance, low temperature resistance and freezing resistance and is convenient to transport, sanitary and safe.

Description

technical field [0001] The invention relates to the technical field of pipe preparation, in particular to a polyethylene composite pipe and a manufacturing method thereof. Background technique [0002] At present, with the rapid development of the construction industry, there is a huge market demand for plastic pipes, and the demand for plastic pipes has reached 100,000-150,000 tons per year. Plastic pipes include PE, PP-R, HDPE and so on. Polyethylene pipes account for a large proportion of plastic pipes. Internationally, polyethylene pipes are divided into five grades: PE32, PE40, PE63, PE80, and PE100. The materials used for gas pipes and water supply pipes are mainly PE80 and PE100. Due to the characteristics of the PE material itself, the PE pipe has low strength, no flame retardancy, limited maximum operating pressure, and poor low temperature resistance. Therefore, while maintaining the original excellent performance of polyethylene pipes, how to improve its tensile...
