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: low-temperature wind energy power cable sheath material-chlorinated polyethylene mixture has average stability and impact strength, cold-resistant reinforcement ℃ PE rubber composition is average

Embodiment 1

[0011] Firstly, 39% CPE rubber, 12% carbon black, 18.5% talc powder, 8.5% light calcium carbonate are blended, and in an internal mixer, the temperature of the stick is 45~60℃ for 27~40min; then add sunflower Dioctyl diacid 4.3% and chlorinated paraffin 4.5%, then add 2.5% accelerator, continue mixing for 3 minutes; then blend with 1.2% paraffin, 2.0% magnesium oxide, 3.0% antimony trioxide, 2.0% decabromide , Continue to mix in the internal mixer for 3 minutes, then add 2.5% DCP vulcanizing agent to mix for 0.5 minutes in the internal mixer, and finally discharge the rubber from the internal mixer, and then unload and pack in the open mixer to obtain the finished product.

Embodiment 2

[0013] First, 37% CPE rubber, 12.5% ​​carbon black, 17.9% talc, and 7.5% light calcium carbonate are blended, and then mixed in an internal mixer at a temperature of 45~60℃ for 27~40min; then add sunflower Dioctyl diacid 4.5% and chlorinated paraffin 5%, then add 2.0% accelerator, continue banburying for 3 minutes; then blend with 2% paraffin, 2.5% magnesium oxide, 3.5% antimony trioxide, and 2.6% decabromide , Continue to mix in the internal mixer for 3 minutes, then add 3.0% DCP vulcanizing agent and mix for 0.5 minutes in the internal mixer, and finally discharge the rubber from the internal mixer, and then unload and pack in the open mixer to obtain the finished product.

Embodiment 3

[0015] First, 40% CPE rubber, 13% carbon black, 16.2% talcum powder, 6.0% light calcium carbonate are blended, and the mixer is mixed at a temperature of 45-60°C for 27-40 minutes; then add sunflower Dioctyl diacid 6% and chlorinated paraffin 4%; then add 3.0% accelerator, continue banburying for 3 minutes; then blend with 3.0% paraffin, 1.8% magnesium oxide, 2% antimony trioxide, 1.8% decabromide , Continue to mix in the internal mixer for 3 minutes, then add 3.2% DCP vulcanizing agent and mix for 0.5 minutes in the internal mixer, and finally discharge the rubber from the internal mixer, and then unload and pack it in the open mixer to obtain the finished product.

[0016] Table 1 is the technical index of Example 1. It can be seen that the performance index greatly exceeds the requirement.

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 followingcomponents 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, 17.2-21.6% of softener, 1.0-1.6% ofparaffin, 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 anddecabromodiphenyl oxide, banburying continuously for 3min, 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 power cables, as a supporting product for wind power generation equipment, are becoming a new type of cable with huge market potential and are being developed and put into the market. The National Wire and Cable Quality Supervision and Inspection Center formally implemented the technical specifications for low-temperature wind energy power cables in May 2009. The specifications are carried out in terms of structural dimensions, materials and performance, voltage levels, ambient temperature, use occasions, and test methods. Detailed Description. Prior to this, low-temperature wind energy power cables had uneve...
