Problems solved by technology
[0002] As we all know, at present, many cold-resistant cable materials are hard at -50°C and lower temperatures, without any flexibility, such as excavator cables used in mining, and radar power transmission lines that need to rotate back and forth in cold regions. Elevator cables used for frequent bending and dragging, etc., if the cables do not meet the cold resistance conditions, these cables will crack, causing short circuits and equipment failures
Even without cracking, cables are cold and hard in cold conditions, unable to bend and move back and forth, which is inconvenient for equipment that needs to be moved frequently

The invention discloses a high-performance cold-resistant soft rubber protective sleeve material, which is prepared from the following raw materials in parts by weight: 90-100 parts of SCR5 natural rubber, 3-5 parts of zinc oxide, 20-25 parts of calcium carbonate, 25-30 parts of talcum powder, 25-30 parts of carbon black, 2.5-3 parts of paraffin, 2.0-2.5 parts of stearic acid, 1-2 parts of an anti-aging agent MB, 0.5-1 part of an anti-aging agent DNP, 0.5-1 part of an accelerant M, 2.5-3 parts of an accelerant TMTD, 0.5-1 part of an accelerant CZ, 0.8-1 part of sulphur and 5-7 parts of an auxiliary. The protective sleeve material disclosed by the invention is good in cold resistance and has flexibility under the environmental condition of -50 DEG C in comparison with common material, the tensile strength of the protective sleeve material can reach 20.0 N / mm<2> above, and the tearing strength can reach 12.0 N / mm<2>, so that the torsion resistance of a cable is improved greatly and the service life of the cable is prolonged greatly.
Description
technical field [0001] The invention mainly relates to the field of cable materials, in particular to a high-performance cold-resistant soft rubber sheath material. Background technique [0002] As we all know, at present, many cold-resistant cable materials are hard at -50°C and lower temperatures, without any flexibility, such as excavator cables used in mining, and radar power transmission lines that need to rotate back and forth in cold regions. Elevator cables used for frequent bending and dragging, etc., if the cables do not meet the cold resistance conditions, these cables will crack, causing short circuits and equipment failures. Even without cracking, cables are cold and stiff in cold conditions, unable to bend and move back and forth, which is inconvenient for equipment that needs to be moved frequently. In response to this situation, our company has developed a high-performance cold-resistant soft rubber sheath material. This material has good cold resis...
