Embodiment 1

[0017] 100g of polyvinyl chloride, 80g of polypropylene, 30g of ethyl acetate, 1g of plasticizer, 20g of calcium carbonate and 2g of stabilizer were mixed and melted (the melting temperature was 150°C and the time was 15min) to form a molten liquid M; After the molten liquid M is subjected to an injection molding process, the high temperature resistant cable sheath is obtained.

Embodiment 2

[0019] 100g of polyvinyl chloride, 90g of polypropylene, 50g of ethyl acetate, 10g of plasticizer, 30g of calcium carbonate and 8g of stabilizer were mixed and melted (the melting temperature was 200°C and the time was 20min) to form a molten liquid M; After the molten liquid M is subjected to an injection molding process, the high temperature resistant cable sheath is obtained.

Embodiment 3

[0021] 100g of polyvinyl chloride, 85g of polypropylene, 40g of ethyl acetate, 5g of plasticizer, 25g of calcium carbonate and 5g of stabilizer were mixed and melted (the melting temperature was 180°C and the time was 18min) to form a molten liquid M; After the molten liquid M is subjected to an injection molding process, the high temperature resistant cable sheath is obtained.

Abstract

The invention discloses a high-temperature-resistant cable sheath and a preparation method thereof. The preparation method comprises: mixing polyvinyl chloride, polypropylene, ethyl acetate, a plasticizer, calcium carbonate and a stabilizer and then melting to form a molten liquid M ; After the molten liquid M is subjected to an injection molding process, the high-temperature-resistant cable sheath is obtained, which solves the problem that the insulating sheath of an ordinary cable has poor high-temperature resistance and is easy to soften and crack at high temperatures.

Description

technical field [0001] The invention relates to the field of cable preparation, in particular to a high temperature resistant cable sheath and a preparation method thereof. Background technique [0002] Cables include power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. Composed of multi-strand wires and insulating layers, they are used to connect circuits, electrical appliances, etc. Cables are often in a high-temperature working environment. The insulation of ordinary cables has poor high-temperature resistance and is prone to softening and cracking at high temperatures. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-temperature-resistant cable sheath and its preparation method, which solves the problem that the insulation sheath of ord...
