MPP power cable tube with high flame retardance and processing technology thereof

Abstract

The invention discloses an MPP power cable tube with high flame retardance and a processing technology thereof. The MPP power cable tube with the high flame retardance is prepared from the following components including, by weight, 70 to 95 parts of isotatic polypropylene resin, 6 to 10 parts of elastomer rubber type CPE, 6 to 10 parts of block co-polypropylene, 20 to 28 parts of ultrahigh molecular weight polyethylene resin, 3 to 5 parts of a flame-retardant filler, 8 to 12 parts of a plasticizer, 1 to 3 parts of an antioxidant, 1 to 4 parts of a light stabilizer, 3 to 8 parts of superfine molybdenum dioxide, 3-8 parts of chromium oxide ultrafine powder and 4-6 parts of a lubricant; An arranged cleaning mechanism is used for cleaning the outer surface of a product, chippings on the surface of the product are removed, and the situation that the winding effect is affected by the chippings is avoided; and the MPP power cable tube with the high flame retardance can be used for winding work of products of different specifications, and the prepared MPP power cable pipe finished product with the high flame retardance has the characteristic of high modulus and is good in flame retardance effect and wear resistance.

Description

technical field [0001] The invention relates to the technical field of cable tubes, in particular to a highly flame-retardant MPP power cable tube and a processing technology 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. The flame retardancy and wear resistance of the existing MPP cable tubes are not good. At the same time, the MPP cable tubes need to be rolled after production to facilitate storage, transportation and access. It is easy for the cable tube to self-roll. At the same time, when the cable tube is in use, the waste will be adsorbed on the entire surface of the cable tube. The surrounding surface of the cable needs to be cleaned to avoid affecting the winding effect. Contents of the invention [0003] In order to overcom...

Problems solved by technology

The flame retardancy and wear resistance of the existing MPP cable tubes are not good. At the same time, the MPP cable tubes need to be rolled after production to facilitate storage, transportation and access. It is easy for the cable tube to be self-rolling. At the same time, when the cable tube is in use, the waste will be adsorbed on the entire surface of the cable tube. It is necessary to clean the cable surrounding surface to avoid affecting the winding effect.
