Problems solved by technology

The purpose of the invention is to eliminate the substances that are easy to blacken the conductor so that the coated copper conductor does not turn black and discolored; because the base material chlorinated polyethylene has poor electrical properties, it can only be used for insulation with low electrical performance requirements such as household appliances, and cannot be used It is suitable for mining cables with high electrical performance requirements; moreover, the rubber still uses DCP vulcanizing agent, which also has the aforementioned disadvantages of odor, and the formula also contains toxic substance dioctyl phthalate, which does not meet environmental protection requirements

Embodiment

[0035] Example: According to the proportion of Table 1 and 2 parts by weight, the rubber insulation and rubber sheath materials are obtained after compounding, mixing, and discharging according to the conventional method, and then the insulation extrusion, cable formation, and sheath extrusion are performed according to the conventional method. Mine cables.

[0036] The samples in the examples were tested for physical and mechanical properties such as tensile strength and elongation, and they all met Table 1 and Table 2 of the mining cable product specification.

[0037] The samples of the examples were subjected to a combustion test, and the results of smoke generation, combustion gas pH, toxicity index, and acetophenone content are shown in Table 3.

[0038] Example samples lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers content detection (RoHS detection), the results are shown in Table 3, fully comply with RoHS requirements.

Abstract

The invention improves rubber insulation material and rubber jacket material for mining cable. Characters are that bitert-butyl isopropyl benzene peroxide is adopted as crosslinking agent; dioctane ester decane diacid is adopted as plasticizer for rubber jacket material; light magnesium oxide is adopted as stabilizer; antimony trioxide is as flame retardant; and aluminum hydroxide and / or magnesiumhydroxide is as flame retardant filler. Advantages of the mining cable are: environmental protective, tested each index accorded with requirement of RoHS, and standard requirement of mining cable.

Description

Technical field [0001] The invention relates to the improvement of the rubber insulating material and rubber sheath material for mining cables, in particular to a rubber insulating material and rubber sheath material for mining cables that meets RoHS environmental protection requirements and is odorless. Background technique [0002] Rubber-sheathed cables are cables composed of rubber insulation and rubber sheaths. As for mining rubber-sheathed cables, the use environment is more severe than other places, so the requirements for cable insulation and sheathing are more stringent. [0003] The existing rubber insulation material for mining rubber-sheathed cables is made of EPDM as the base material and added with known amounts of reinforcing agents, crosslinking agents, crosslinking aids, plasticizers, coupling agents, antioxidants and fillers. The crosslinking agent used in the formula is basically dicumyl peroxide (DCP). When this crosslinking agent is vulcanized, it will produce...
