Abstract

The invention relates to the cable field, and especially relates to a cable insulation layer and a making method thereof. The making method of the cable insulation layer comprises the following steps: adding a modifier to gangue particles to modify the gangue particles in order to change the hydrophilicity of the gangue particles to lipophilicity; mixing the modified gangue particles with a rubber-plastic elastomer, and stirring to obtain a first mixed material; adding the modifier, a lubricant, a heat stabilizer, a vulcanizing agent and stearic acid to the first mixed material to obtain a second mixed material; and sequentially carrying out internal mixing and open milling of the second mixture to obtain the cable insulation layer. The main components comprising the gangue particles and the rubber-plastic elastomer of the cable insulation layer have low prices, so the cost of the made cable insulation layer is low, thereby the cable insulation layer has the advantages of guaranteed insulation performance and low material cost.

Description

technical field

[0001] The invention relates to the field of cables, in particular to an insulating layer of cables and a manufacturing method thereof. Background technique

[0002] At present, the insulation layer of common cables is mostly made of ethylene-propylene rubber with EPDM rubber, binary ethylene-propylene rubber, modified ethylene-propylene rubber and thermoplastic ethylene-propylene rubber as the main components.

[0003] However, in related technologies, due to the high price of ethylene-propylene rubber, the cost of the insulating layer made of ethylene-propylene rubber as the main material is correspondingly high; An insulating layer with low material cost is a technical problem to be solved urgently in this field. Contents of the invention

[0004] The object of the present invention is to provide an insulating layer of a cable and a manufacturing method thereof, so as to solve the above-mentioned problems.

[0005] An embodiment of the present inventio...
