High-strength insulating MPP power cable tube and preparation method thereof

Abstract

The invention discloses a high-strength insulating MPP power cable tube and a preparation method thereof. The high-strength insulating MPP power cable tube comprises the following components in parts by weight: 75-85 parts of isotactic polypropylene resin, 6-10 parts of elastomer rubber type CPE, 7-9 parts of block co-polypropylene, 24-26 parts of ultra-high molecular weight polyethylene resin, 3-5 parts of a flame retardant, 8-12 parts of a plasticizer, 1-3 parts of an antioxidant, 1-4 parts of a light stabilizer and 2-5 parts of a mixed auxiliary material. The preparation method comprises the steps of 1, weighing isotactic polypropylene resin, elastomer rubber type CPE, block co-polypropylene, ultra-high molecular weight polyethylene resin, a flame retardant, a plasticizer, an antioxidant, a light stabilizer and a mixed auxiliary material in parts by weight. The cable tube body prepared by the invention has high strength while having good insulativity, so that the cable tube body is ensured to have good wear resistance and longer service life during application.

Description

technical field [0001] The invention relates to the technical field of cable tubes, in particular to a high-strength insulating MPP power cable tube and a preparation method thereof. Background technique [0002] MPP power pipes are divided into ordinary type and reinforced type, and reinforced type is divided into excavated pipe and non-excavated pipe. The so-called MPP non-excavated pipe is also called MPP jacking pipe, MPP drag pipe, and MPP traction pipe. MPP power pipes use modified polypropylene as the main raw material. It is not necessary to dredge a lot of mud, dig soil and damage the road surface, and lay pipes, cables and other construction projects in special areas such as roads, railways, buildings, and river beds. Compared with the traditional "grooving and buried pipe method", the non-excavation power pipe project is more suitable for the current environmental protection requirements, and removes the dust, traffic congestion and other disturbing factors caused...
