Problems solved by technology

At present, CPVC materials have been used to prepare power cable casings in China, but there are generally problems such as unstable product performance, difficult processing, high cost, and complicated mixing process, which prevents CPVC pipes from being widely used.
[0003] At present, the CPVC power cable pipe material formulations on the market are basically produced abroad, with good processing performance and stable performance indicators, but the price is generally high; while the development of domestic CPVC power cable formulations started late and the level is low , which makes the processing of domestic formula materials difficult and the performance index of the product is low
The domestic production of CPVC formulations basically follows the PVC formulation technology, and the additives used are also common additives for processing PVC. There is no special additive developed according to the characteristics of CPVC materials, so it is impossible to prepare formulations with excellent performance.

Abstract

The invention discloses CPVC for a power cable sleeve and a preparation method thereof. The CPVC consists of the following raw materials in parts by weight: 50-70 parts of CPVC resin, 30-50 parts of PVC resin, 2.5-5 parts of a stabilizer, 2-3 parts of a lubricating anti-impact modifying agent, 2-4 parts of a lubricating processing aid, 10-30 parts of a filling material and 0.02-0.2 part of a pigment. The prepared compound material disclosed by the invention is simple in mixing process and easy to process; pipes prepared are 93-95 DEG C in Vicat temperature, and various physical indexes achieve standard of the power cable sleeve; moreover, the CPVC is low in cost, good in weather fastness and good in flame retardance.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a CPVC for power cable casing and a preparation method thereof. Background technique [0002] At present, power cables in towns and industrial parks are mostly protected by hard polyvinyl chloride plastic sleeves. This material has good corrosion resistance, light weight, low cost, and simple installation. However, its long-term use temperature does not exceed 50°C, the strength and toughness are small, the weather resistance is poor, and it is easily broken, which will easily affect the overall project quality during the construction process. CPVC material has become an ideal material for power cable bushings because of its high strength, good heat resistance and good weather resistance. Foreign countries have been developing and researching CPVC materials for a long time, and have successfully applied CPVC pipes to the field of power cable casings. At present, CPV...
