Problems solved by technology

However, since the main base rubber of this invention is EPDM rubber, the price is relatively high, resulting in an increase in cost, which is not conducive to the promotion of commercialization
[0009] As the price of EPDM increases year by year, the cost of using EPDM as mining cable rubber sheath increases, which seri

Embodiment

[0037] According to the conventional method in this field, the CPE base rubber is first kneaded on a small open mill, and after molding, the EPDM base rubber is added for mixing and masticating. After being fully mixed, all auxiliary materials except the vulcanizing agent and vulcanization aid are added for mixing. Refining, adding vulcanizing agent and vulcanizing aids after forming, mixing, uniform and cooling to obtain sheath rubber, and then insulating extrusion according to conventional methods to obtain mining cable rubber sheath rubber.

[0038] Shown below is the specific formula of each embodiment.

Embodiment 1

[0040]

[0041] Wherein, the mass ratio of EPDM rubber to chlorinated polyethylene is 1:3.

Embodiment 2

[0043]

[0044]

Abstract

The invention relates to a mining cable rubber sheath glue, which comprises the following raw material components according to parts by weight: 10-30 parts of ethylene propylene diene monomer rubber, 30-90 parts of chlorinated polyethylene, 1-6 parts of vulcanizing agent, 2-5 parts of vulcanizing auxiliary agent, 5-40 parts of reinforcing agent, 1-8 parts of anti-aging agent, 20-40 parts of filling agent, 5-35 parts of plasticizer, 0.5-3 parts of coloring agent, 5-10 parts of stabilizing agent, 1-3 parts of active agent and 30-80 parts of fire retardant, wherein the mass ratio of the ethylene propylene diene monomer rubber to the chlorinated polyethylene is 1:3. In the mining cable rubber sheath glue, the chlorinated polyethylene is adopted to replace parts of ethylene propylene diene monomer rubber, the formula of the raw material is regulated, and the use cost of the prepared mining cable rubber sheath glue is lowered on the premise of satisfying the use standard of the mining cable.

Description

technical field [0001] The invention relates to a cable sheath glue, in particular, the invention relates to a mining cable rubber sheath glue. Background technique [0002] Mining cables refer to wire and cable products for ground equipment and underground equipment used in the coal mining industry. These include cables for coal mining machines, conveyors, communications, lighting and signaling equipment, as well as cables for electric drills, cap lamp wires and power cables for underground mobile substations. The best working performance and safety performance of cables are closely related to mining conditions, which require materials with good dielectric properties, heat resistance, chemical properties and mechanical properties. Mining cables are mainly composed of two parts: insulating glue and sheath glue. [0003] Ethylene-propylene-diene rubber (EPDM) is a kind of rubber with good comprehensive properties. There is no unsaturated bond in its molecular main chain, so...
