Flame-retardant cold-resistant impact-resistant rubber cable sheath and preparation method thereof

Abstract

The invention discloses a flame-retardant cold-resistant impact-resistant rubber cable sheath which is prepared from the following raw materials in parts by weight: 55-65 parts of chlorinated polyethylene, 10-15 parts of ethylene-propylene rubber, 3-4 parts of sulfur powder, 1.5-2.5 parts of accelerator DM, 1-2 parts of accelerator TMTM, 5-8 parts of trioctyl trimellitate, 3-4 parts of tributyl citrate, 12-14 parts of pretreated fiber powder, 15-20 parts of barite powder, 6-9 parts of magnesium oxide, 35-40 parts of meerschaum powder, 12-16 parts of hard clay, 8-10 parts of red phosphorus, 5-8 parts of aluminum hydroxide, 10-15 parts of magnesium hydroxide, 5-8 parts of diisooctyl phthalate, 7-11 parts of phenyl petroleum sulfonate, 2-3 parts of anti-aging agent RD, 2.1-2.4 parts of anti-aging agent, 25-35 parts of dioctyl adipate and 5-7 parts of stearic acid. The lame-retardant cold-resistant impact-resistant rubber cable sheath has the advantages of favorable flame-retardant effect, high cold resistance and high shock resistance.

Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to a flame-retardant, cold-resistant and impact-resistant rubber cable sheath and a preparation method thereof. Background technique [0002] Electricity is an important support for the development of the national economy. As the carrier of electric power transmission, cables are widely used in production, living and geographical areas. However, in some areas such as northern my country, the winter climate conditions are relatively harsh, and open-air use such as mine cables, wind energy cables, mechanical cables, etc. during frequent movement or rotation must resist the impact of severe weather, so the cable Performance puts high demands on it. Ordinary cables have poor resistance to the external environment and short service life. When used in this environment, they are prone to cracking or even breaking due to cold and impact, which reduces the reliability of the cable and ...

AI Technical Summary

Problems solved by technology

Ordinary cables have poor resistance to the external environment and short service life. When used in this environment, they are prone to cracking or even breaking due to cold and impact, which reduces the reliability of the cable and poses a threat to safe production; at the same time, the cables used in the machine Due to frequent friction or possible contact with sparks, high requirements are placed on the flame retardancy of cables
