Abstract

The invention discloses a double-wall corrugated pipe with a wear-resistant inner wall and a preparation method thereof. The double-wall corrugated pipe comprises a pipe inner wall base and a polyethylene corrugated pipe layer, the pipe inner wall base comprises, by weight, 50 to 80 parts of PE, 50 to 80 parts of POE, 10 to 50 parts of UHMWPE, 1 to 10 parts of silane, 0.1 to 0.5 parts of an initiator, 0.1 to 0.5 parts of an amine catalyst, 10 to 50 parts of a filler and 2 to 10 parts of a lubricant. After mortar swinging friction on the inner wall of the pipe 100000 times, the double-wall corrugated pipe with a wear-resistant inner wall has a wear rate reduced to 2% or less from 5% and improves wear resistance by 1 time or more. The double-wall corrugated pipe has physical and mechanical properties satisfying the national standard requirements, improves inner wall wear resistance, effectively prolongs a pipe service life and can be widely used in a sewage pipe network, drainage in residential quarters, rain and sewage diversion, industrial park wastewater discharge and drainage of large facilities.

Description

technical field

[0001] The invention belongs to the technical field of pipe material preparation, and in particular relates to a wear-resistant double-wall corrugated pipe with an inner wall widely used in the fields of drainage and sewage pipe network construction and a preparation method thereof. Background technique

[0002] With the acceleration of urbanization in my country, the construction scale of underground pipe network systems is expanding day by day. Double-wall corrugated pipes are widely used in drainage and sewage pipe network projects by virtue of their significant advantages such as corrosion resistance, light weight, convenient installation, and low comprehensive engineering cost. developed rapidly. However, in practical applications, since various sediments often exist in the fluid transported by the pipeline, different degrees of impact and cutting will occur on the inner wall, which will easily cause the wear of the pipe wall. The inner wall of the doubl...
