Problems solved by technology

Although the HDPE single-wall corrugated pipe has the characteristics of elasticity and non-directional bending, when it is used as a cable protection sleeve, especially when the cable is installed underground, it often has insufficient rigidity, especially the insufficient ring rigidity, and the ability to resist external pressure is insufficient, which is not conducive to the internal pressure of the pipe. Cable protection and installation construction

Abstract

The invention relates to a single-wall corrugated pipe and a manufacture method for the same. The single-wall corrugated pipe is made of, by weight, the ingredients including 100 parts of high densitypolyethylene, 8-12 parts of micron glass fibers, 5-7 parts of silane coupling agent, 2-3 parts of water, 5-10 parts of polypropylene filament drawn materials, 7-10 parts of talcum powder, 0.1-0.3 part of lead stearate, 0.3-0.5 part of stearic acid and 0.3-0.5 part of polyethylene wax. Properties of the high density polyethylene can be improved with the polypropylene filament drawn materials, so strength and rigidity of the corrugated pipe can be enhanced. The single-wall corrugated pipe which is manufactured with the high density polyethylene as a matrix and the polypropylene filament drawn materials as a modified material can be reinforced and modified with the micron glass fibers; the silane coupling agent is uniformly and stable dispersed in the matrix and has an interface reaction with the polypropylene filament drawn materials, so uniformity of mixing between the polypropylene filament drawn materials and the matrix is enhanced and ring rigidity, overall rigidity and use stability of the single-wall corrugated pipe can be enhanced; and with the higher rigidity, the single-wall corrugated pipe can be installed more easily.

Description

technical field [0001] The invention relates to the technical field of bellows, in particular to a single-wall bellows and a manufacturing method thereof. Background technique [0002] Bellows are cylindrical, thin-walled corrugated shells with multiple transverse corrugations. Bellows are generally made of PE, PP or PA materials, which have the characteristics of light weight, high elasticity, corrosion resistance and good processing performance, and the bellows have non-directional bending characteristics due to multiple transverse corrugations, making them widely used in Construction, machinery and other fields. [0003] Single-wall corrugated pipes made of HDPE (high-density polyethylene) can be used in the power field and are often used as protective sleeves for cables. Although the HDPE single-wall corrugated pipe has the characteristics of elasticity and non-directional bending, when it is used as a cable protection sleeve, especially when the cable is installed und...
