Materials for non-excavation cable protection pipes and cable protection pipes

Abstract

The invention relates to a material for a non-excavation type cable protection pipe and a cable protection pipe, wherein the material is formed by mainly compounding modified polypropylene (MPP) and LDPE (low-density polyethylene), the modified polypropylene is a polypropylene reclaimed material, and the material comprises the following components in percentage by weight: 75-85 percent of MPP, 10-15 percent of LDPE, 0.1-1 percent of initiator, 0.5-6 percent of accessory ingredient, 0.1-0.5 percent of antioxidant and 1.5-2.5 percent of color masterbatch. Compared with the traditional MPP material for the cable protection pipe, the material for the non-excavation type cable protection pipe has the characteristics of good rigid-flexible combination property, low raw material cost and good market application prospect.

Description

technical field

[0001] The invention relates to a material for a non-excavation type cable protection pipe and a non-excavation type cable protection pipe formed therefrom. Background technique

[0002] With the introduction of non-excavation technology, major cities have adopted a large number of underground non-excavation technology to lay plastic cable pipes to transmit electricity, and the demand has increased dramatically. At present, the non-excavation type MPP cable protection tube occupies a large proportion in the market. Modified polypropylene (MPP) pipe has excellent characteristics such as light weight, good comprehensive performance of rigidity and flexibility, high welding strength, and good high and low temperature resistance. However, compared with PE pipes, the cost price of MPP pipes is higher. In the production process, how to further reduce the cost on the basis of maintaining the performance of the existing MPP pipe is a key task. Contents of the inv...
