Problems solved by technology

[0002] At present, the power cable protection tube is mainly made of polyvinyl chloride material in production and application. This material has the advantages of good corrosion resistance, processing performance, and low cost, but its heat resistance is not high, low strength, high brittleness, and high resistance. Poor impact, poor flame retardant effect, easy to break during production, transportation and construction, and prone to transmission failures in environments with high heat generation, large amount of information transmission, and harsh transmission environments. MPP materials have now been used to prepare electricity Cable protection tube
[0003] At present, the strength and toughness of the existing MPP cable protection tubes cannot fully adapt to the high-demand environment, resulting in a small scope of application.

Abstract

The invention relates to the technical field of cable protection pipes, in particular to a high-strength MPP cable protection pipe which comprises MPP resin masterbatch, low-density polyethylene resin masterbatch, a composite base material, modified acrylic resin, a cross-linking agent, an antioxidant, a flame retardant, an ultraviolet light absorber and a plasticizer, and the high-strength MPP cable protection pipe comprises, by weight, 200 to 240 parts of the MPP resin masterbatch, 100 to 150 parts of the low-density polyethylene resin masterbatch, 80 to 100 parts of the composite base material, 50 to 80 parts of the modified acrylic resin, 10 to 15 parts of the cross-linking agent, 10 to 15 parts of the antioxidant, 5 to 8 parts of the flame retardant, 5 to 9 parts of the ultraviolet absorbent and 10 to 15 parts of the plasticizer. The MPP cable protection pipe can effectively solve the problem that the existing MPP cable protection pipes cannot completely adapt to environments with high requirements in strength and toughness, so that the application range of the MPP cable protection pipes is relatively small.
