Modified polypropylene cable protection pipe and forming process thereof

Abstract

The invention discloses a modified polypropylene cable protection pipe and a forming process thereof. The pipe is prepared from the following components in parts by weight: 100 parts of modified polypropylene, 1 to 5 parts of a tackifier, 0.5 to 5 parts of glass fiber, 1 to 5 parts of an anti-impact modifier, 1 to 5 parts of a nucleating agent, 0 to 10 parts of a filling matrix, 0.1 to 3 parts of an antioxidant, 0.1 to 3 parts of a light stabilizer and 2 to 8 parts of rubber. On the basis of modified polypropylene, the comprehensive performance of the modified polypropylene cable protection pipe can be improved by adding the components such as the tackifier, the glass fiber, the anti-impact modifier, the nucleating agent, the filling matrix, the antioxidant, the stabilizer, the rubber and the; particularly by the adding of the glass fiber, the performance such as the mechanical property and the corrosion resistance of the pipe are greatly improved.

Description

technical field [0001] The invention relates to a cable protection pipe, in particular to a modified polypropylene cable protection pipe and its forming process. Background technique [0002] As a thermoplastic resin with excellent comprehensive properties, polypropylene (PP) has the advantages of abundant raw material sources, good mechanical properties, low density, and good chemical stability. It is widely used in the plastics and fiber industries. However, due to the flexibility of the PP molecular chain Large, high melt extrusion elasticity, polypropylene has the disadvantage of low impact strength, especially low temperature impact strength, and it is usually difficult to achieve both fluidity and mechanical properties, which limits the application of PP to a certain extent. In order to improve the performance of polypropylene and expand its application range, a lot of research has been done on modified PP at home and abroad. [0003] The power cable protection pipe i...
