Problems solved by technology

Traditional cable sheaths are difficult to have heat resistance and oil resistance at the same time, especially when the cable sheath has heat resistance, the material contains a high content of organic matter, it is easy to expand and deform when exposed to hot oil, and it is easy to become soft and rotten after soaking for a long time. Oil resistance is difficult to guarantee
At the same time, the traditional cable sheath will emit peculiar smell when heated, causing heavy metal poisoning, etc.

Abstract

The invention discloses a heatproof and oil-resistant cable wrapping and belongs to the technical field of cables. The heatproof and oil-resistant cable wrapping is obtained by a reaction among the following raw materials, by weight, 80-90 parts of suspension polymerized polyvinyl chloride resin, 10-15 parts of a plasticizer, 4-6 parts of a compound stabilizer, 2-3 parts of an antioxidant and 20-30 parts of a filler, wherein the filler is calcined ceramic clay and / or calcium carbonate. Through combination of various ingredients, oil resistance and heat resistance of the heatproof and oil-resistant cable wrapping are guaranteed. In addition, as there is no lead or cadmium in the formula, heavy metal poisoning can be prevented after the cable wrapping is heated. The cable wrapping is environmentally friendly and durable.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a heat-resistant and oil-resistant cable sheath. Background technique [0002] Cable sheath is widely used in the cable manufacturing process. Its withstand voltage and insulation resistance are relatively high, but its dielectric constant and dielectric loss are relatively large. Generally, it is mainly used as insulation for low-voltage (≤1KV) and medium-high voltage (6~10KV) cables. Floor. Traditional cable sheaths are difficult to have heat resistance and oil resistance at the same time, especially when the cable sheath has heat resistance, the material contains a high content of organic matter, it is easy to expand and deform when exposed to hot oil, and it is easy to become soft and rotten after soaking for a long time. Oil resistance is difficult to guarantee. At the same time, the traditional cable sheath will emit peculiar smell when heated, causing heavy me...
