Problems solved by technology

[0003] However, due to the high vertical stiffness of polypropylene but poor toughness, especially in low temperature environment, brittle failure is easy to occur, which seriously affects the service life of the pipe.
At the same time, due to the long construction period of the current excavation power project, especially in the south, the pipes are placed on the construction site for a long time and the light intensity is high, which will easily lead to the aging of the pipes, such as lightening of the color and deterioration of the material.

Abstract

The invention relates to a sun-proof composite modified polypropylene pipe for power cable protection. The pipe comprises the following components in percentage by weight: 73 to 78 percent of PP (Propene Polymer), 10 to 15 percent of POE (Polyolefin Elastomer), 4.8 to 5.2 percent of nano calcium carbonate, 0.3 to 0.4 percent of nucleating agent, 0.2 to 0.25 percent of coupling agent and 0.5 to 1 percent of sun-proof lubricating composite functional master batch. Not only does the pipe have better low-temperature impact resistance, wherein impact energy in a falling weight impact test at a temperature of minus 5 DEG C is improved by over 2.5 times, the friction coefficient is reduced by 40 percent and the Vicat heat-resistance temperature is risen by 5 DEG C, but also sun-proof performance of the pipe is improved and the application range of the power pipe is enlarged.

Description

technical field [0001] The invention relates to the field of pipes, in particular to a light-resistant composite modified polypropylene pipe for power cable protection. Background technique [0002] At present, the raw materials used for pipes on the market are mainly concentrated in polyvinyl chloride and high-density polyethylene. With the improvement of environmental protection awareness, polyvinyl chloride has gradually withdrawn from the market. Compared with polyethylene, polypropylene has a higher elastic modulus and lower density, and its cost performance is relatively high. [0003] However, due to the high vertical stiffness of polypropylene but poor toughness, especially in low temperature environment, brittle failure is easy to occur, which seriously affects the service life of the pipe. At the same time, due to the long construction period of the current excavation power projects, especially in the south, the pipes are placed on the construction site for a long...
