Abstract

The invention relates to a low-smoke zero-halogen flame retardant EVA rubber sheath material for a mine cable. The low-smoke zero-halogen flame retardant EVA rubber sheath material comprises the following components by weight: 100 parts of EVA resin, 110-130 parts of magnesium hydrate, 10-18 parts of carbon black, 1-5 parts of an antiager RD, 2-8 parts of DEP dioctyl ester, 2-8 parts of paraffin,0.5-2 parts of a silane coupling agent, 1-5 parts of stearic acid, 1-5 parts of a release agent, 1-5 parts of a vulcanizing agent DCP and 1-5 parts of a crosslinking agent TAIC, the preparation sequentially comprises the steps of preparing the materials, mixing, sulphurating, discharging a sheet, extruding and forming. A preparation method is simple, the steps are easy to operate, the EVA resin istaken as a main body and the magnesium hydrate is taken as a flame retardant to prepare and obtain the rubber sleeve material, the tensile strength of the rubber sleeve material is large, the rubbersleeve material is better in light transmittance in the combustion, the toxicity index is low, the corrosive PH value is higher than the national standard requirement, and the low-smoke zero-halogen flame retardant EVA rubber sheath material meets the requirements of low smoke, zero halogen, flame retarding and low toxicity of the mine cable.

Description

technical field [0001] The invention relates to a low-smoke, halogen-free, flame-retardant EVA rubber sheath material for mine cables and a preparation method thereof, belonging to the technical field of cable preparation. Background technique [0002] At present, the mining cables used in China must comply with the regulations of MT 818-2009, and must obtain the MA certificate issued by the Anbiao National Mining Product Safety Mark Center before they can be used. The flame retardant performance of the cable complies with the regulations of MT 386-2011, and the sheath material that meets the flame retardant performance is usually chlorinated polyethylene, neoprene and chlorosulfonated polyethylene rubber sheath materials containing chlorine, but the national The standard has no requirements on the low-smoke, halogen-free and low-toxic properties of mining cable materials, and has no environmental protection. For mining cables made of chlorine-containing chlorinated polyeth...
