UHMWPE composite double-wall corrugated pipe

Abstract

The invention relates to the field of plastic pipes, and provides a UHMWPE composite double-wall corrugated pipe, which comprises an inner wall and an outer wall. The inner wall is prepared from the following raw materials in parts by weight: 100 to 120 parts of low-density polyethylene, 3 to 5 parts of color master batch, 4 to 6 parts of a moisture absorbent and 4 to 6 parts of antioxidant master batch. The outer wall is prepared from the following raw materials in parts by weight: 30 to 40 parts of ultra-high molecular weight polyethylene, 70 to 80 parts of high-density polyethylene, 10 to 20 parts of reinforced master batch, 1 to 2 parts of a nucleating agent, 3 to 5 parts of black color master batch, 4 to 6 parts of antioxidant master batch and 4 to 6 parts of a moisture absorbent. According to the UHMWPE composite double-wall corrugated pipe, the ring stiffness and the wear resistance are improved, and the application field of the pipe is expanded.

Description

technical field

[0001] The invention relates to the field of plastic pipes, in particular to a UHMWPE composite double-wall corrugated pipe. Background technique

[0002] Due to its special structural design, the PE double-wall corrugated pipe has a straight inner wall and a ring-shaped corrugated outer wall, which reduces the material consumption and endows the pipe with excellent performance. It is one of the most widely used pipes in the field of drainage and sewage. It is widely used in Municipal engineering underground buried rain and sewage discharge, farmland water conservancy irrigation projects, chemical engineering, communication cable protection sleeves, etc.

[0003] With the change of the application environment, PE double-wall corrugated pipe also has the problem of insufficient rigidity or poor toughness. In addition to optimizing the structure, the optimization of the formula system is the main means of changing the pipe.
