Problems solved by technology

However, due to the limitation of technical conditions, the existing low-temperature wind energy power cable production enterprises cannot actually meet the above performance requirements; this is because the outer sheath of the conductive core needs to withstand low temperature and cold temperature, which is easy to age
The main reasons for these defects are: the stability and impact strength of the low-temperature wind power cable sheath material-chlorinated polyethylene mixture is average, and the composition of the cold-resistant reinforcing CPE compound is average

Abstract

The invention discloses chlorinated polyethylene used for the preparation of a low temperature wind energy cable and a preparation method thereof. The chlorinated polyethylene comprises the following components by weight percent: 36-42% of CPE rubber, 11.2-15.2% of carbon black, 16-20% of talcum powder, 6-10% of light calcium carbonate, 1.6-4.0% of accelerator, 4-7% of octyl sebacate, 4-6% of chlorcosane, 1.0-1.6% of paraffin, 2-5% of antimonous oxide, 1.6-3.0% of magnesium oxide, 1.6-4% of decabromodiphenyl oxide and 1.8-3.6% of DCP vulcanizing agent. The preparation method comprises the following steps: mixing CPE rubber, carbon black, talcum powder and light calcium carbonate, then adding softener, banburying for 27-40min, then adding accelerator, mixing with paraffin, magnesium oxide, antimonous oxide and decabromodiphenyl oxide, banburying continuously, and then adding DCP vulcanizing agent to banburying for 0.5min. The cable prepared from the material can not age and can maintain performances at -40 DEG C after a long time use.

Description

technical field [0001] The invention relates to a material for producing low-temperature wind energy cables, in particular to a chlorinated polyethylene mixture. In addition, the invention also provides a preparation method of the chlorinated polyethylene. Background technique [0002] As the country's demand for renewable energy continues to increase, low-temperature wind energy power cables, as a supporting product for wind power generation equipment, are becoming a new cable variety with huge market potential, developed and put into the market. The National Wire and Cable Quality Supervision and Inspection Center officially implemented the technical specifications for low-temperature wind energy power cables in May 2009. A detailed description. Prior to this, low-temperature wind energy power cables had mixed product quality, and a large number of unqualified or bad products flooded the market, causing economic losses to users and seriously threatening the normal operat...
