Problems solved by technology

However, chlorinated polyethylene has poor electrical insulation performance and is not suitable for making insulating materials.
Styrene-butadiene rubber is heat-resistant, aging-resistant, and has good electrical properties. The unit price is less than half of that of ethylene-propylene rubber, and the price is cheap. However, styrene-butadiene rubber is resistant to ozone and has poor weather resistance.

Abstract

The invention discloses a composite insulation material for a cable and a preparation method thereof. The composite insulation material for a cable comprises the following materials by weight part: 30-60 parts of EPDM rubber, 70-40 parts of styrene-butadiene rubber, 1-4 parts of cross linker, 1-6 parts of cross linker addition agent, 4-16 parts of vulcanizing active agent, 1-4 parts of aging inhibitor, 10-40 parts of plasticizer, 1-3 parts of coupling agent and 100-200 parts of reinforcement filling material. The preparation method comprises the following steps: weighing the materials according to the weight parts; mixing; tabletting; cooling; and collecting. The composite insulation material is used for cable low-voltage insulation, has a temperature resistant level capable of reaching 90 DEG C, can resist heat, ozone and weathers and has high tensile strength, good electrical insulating property and mechanical property and cost being far lower than the cost of ethylene propylene rubber, and the preparation method is simple, applicable and easy to operate.

Description

technical field [0001] The invention relates to a composite insulating material and a preparation method thereof, in particular to a composite insulating material for cables and a preparation method thereof, which is suitable for low-voltage insulation of cables with a temperature resistance level of 90°C. Background technique [0002] Ethylene-propylene rubber has excellent heat resistance, ozone resistance, weather resistance, low temperature resistance and electrical insulation and is used in the field of wire and cable. It has been recognized as a heat-resistant 90°C insulating material and a good high-voltage insulating rubber. It is widely used in 35KV and The following power cables, marine cables, flexible cables for mines, cables for locomotives, mobile high-voltage cables, heat-resistant connecting wires for daily appliances, etc. However, ethylene-propylene rubber has poor self-adhesion and mutual adhesion, difficult processing technology, and high cost, and the co...
