Problems solved by technology

Therefore, it can also be used as the main material of insulating materials. Using polyolefin elastomer (POE) alone as the main material of insulating materials has poor electrical properties, low volume resistivity, poor pressure resistance, poor elasticity, and heat and oxygen resistance. There is a certain gap in aging and ozone aging resistance compared with EPDM rubber

Description

technical field [0001] The invention relates to a cable insulating material, which belongs to the technical field of chemical industry, in particular to a composite insulating material for coal mine cables. Background technique [0002] At present, the insulating materials used in domestic coal mine cables are all made of EPDM rubber or polyolefin elastomer (POE) as the single main material. EPDM rubber is used as the main material of coal mine cable insulation, its performance characteristics: (1) high cost performance, raw rubber density is only 0.86 ~ 0.90kg / m 3 , is the commonly used rubber with the lightest raw rubber density; and it can be filled in large quantities to reduce the cost of the rubber compound. (2) Excellent aging resistance, weather resistance, ozone resistance, sunlight resistance, thermal oxygen resistance, water resistance, water vapor resistance, ultraviolet resistance, radiation resistance and other aging properties. (3) Excellent chemical resista...
