Problems solved by technology

But it's expensive
[0006] At present, with the continuous expansion of the application range of cable sheaths, more stringent requirements are put forward for cable sheaths. Most of the mine cables are used in the harsh environment of underground mines. Most of them are high-temperature, flammable, humid and corrosive underground. Existing The mine cable sheathing material faces many product technical problems, and there is still a lot of room for improvement to meet the more stringent demands of the cable market

Abstract

The invention provides an oil-resistant and high-temperature-resistant mining cable sheath material and a method for preparing the same. The oil-resistant and high-temperature-resistant mining cable sheath material comprises, by weight, 30-40 parts of chloroprene rubber, 25-35 parts of fluorine-silicon rubber, 20-30 parts of chlorosulfonated polyethylene rubber, 10-15 parts of fluoroether rubber, 6-8 parts of carbon nanometer fibers, 35-45 parts of carbon black, 10-15 parts of plasticizers TOTM, 8-12 parts of compound stabilizers, 2-4 parts of anti-aging agents 4010NA, 0.5-1.5 parts of anti-aging agents ODA, 0.8-1.2 parts of dicumyl peroxide, 6-10 parts of talc powder, 10-15 parts of compound flame retardants, 1-3 parts of accelerators TMTD, 10-20 parts of diatomaceous earth and 20-25 parts of modified kaolin. The oil-resistant and high-temperature-resistant mining cable sheath material and the method have the advantages that the chloroprene rubber, the chlorosulfonated polyethylene rubber, the fluorine-silicon rubber and the fluoroether rubber are compounded with one another, accordingly, the processing property and the mechanical property of the oil-resistant and high-temperature-resistant mining cable sheath material can be improved while the original properties of raw materials for the oil-resistant and high-temperature-resistant mining cable sheath material in a formula are guaranteed, the oil-resistant and high-temperature-resistant mining cable sheath material is excellent in physical and mechanical property, good in oil resistance, high-temperature resistance, abrasion resistance and insulating and flame-retardant property and long in service time, and the aging speeds can be obviously lowered.

Description

technical field [0001] The invention belongs to the technical field of cable sheathing materials, and in particular relates to an oil-resistant and high-temperature-resistant mining cable sheathing material and a preparation method thereof. Background technique [0002] Chloroprene rubber is a synthetic rubber made of chloroprene (ie 2-chloro-1,3-butadiene) as the main raw material for α-polymerization. Because it contains chlorine atoms in its molecule, it has excellent anti-oxidation and ozone resistance, non-flammability, oil resistance, solvent resistance, acid and alkali resistance, aging resistance, and good air tightness; its physical and mechanical properties are also better than natural rubber. Therefore, it can be used as general-purpose rubber or special rubber. But this kind of rubber has poor cold resistance, relatively high cost, especially poor electrical insulation and poor processability. [0003] Chlorosulfonated polyethylene is a chlorine-containing spec...
