Problems solved by technology

[0003] Although the prior art has reported conductors and insulating shielding materials used in cables for high-voltage high-speed railway trains, the basic materials such as polyethylene or polypropylene used in the prior art lead to the use of high-voltage high-speed train cables made of this material are soft at room temperature Performance, shielding performance, high temperature resistance (140°C), oil resistance and flame retardancy are not ideal

Embodiment 1

[0056]First take 300 grams of basic rubber, knead it on a small open mill, add fine materials, stabilizers, anti-aging agents, some conductive carbon black agents and plasticizers, etc. after fully covering the rolls, add the remaining conductive carbon black and plasticizer after basic molding Plasticizer, after adding vulcanizing agent and vulcanizing aids to form, the pitch of the rollers in the small machine is reduced, the rubber is made into thin sheets, and the rubber is made into triangle bags for at least 5 times, and then the sheets are cooled for later use.

Embodiment 2

[0058] Put 27 kg of masticated basic rubber into the internal mixer for 30 seconds to 1 minute, then add anti-aging agent, stabilizer, half of plasticizer, filler, and half of conductive carbon black for about 2 to 3 minutes, then add the rest After 1 to 2 minutes of plasticizer and conductive carbon black, after forming, put the material on the open mill for mixing for about 3 minutes, press the tablet, open the strip and filter the rubber, cool the tablet for later use, the thickness of the tablet is about 2mm, park it for at least After 4 hours, weigh 87.00 kg of unvulcanized rubber and put it into the internal mixer for mixing for about 3 minutes, then add 3.00 kg of vulcanizing agent and vulcanizing aid for 30 seconds to 1 minute. Afterwards, the strips are turned and rolled out for cooling and standby. The thickness of the strips is 2.00mm and the width is 180-250mm.

Abstract

The present invention discloses a 125 DEG C resistance low smoke non-halogen rubber-sheathed cable shielding material, including 100.00 shares of ethylene/ethylene acetic acid rubber, 60.00 to 100.00 shares of conductive carbon black, 40.00 to 60.00 shares of light calcium carbonate, 10.00 to 15.00 shares of plasticizer, 0.50 to 1.00 shares of active agent, 1.50 to 2.00 shares of anti-aging agent, 0.50 to 1.00 shares of technology operating agent, 1.50 to 2.00 shares of Di(tert-butylperoxyisopropyl)benzene, and 1.00 to 3.00 shares of triallyl isocyanurate. The rubber shielding cable material has characteristics of high temperature resistance, high conductivity, low smoke, non halogen, oil resistance, very plasticity and the like.

Description

technical field [0001] The invention relates to a conductor and an insulation shielding cable material for a high-voltage high-speed railway motor vehicle cable, in particular to a 125°C-resistant low-smoke halogen-free rubber cable shielding material. Background technique [0002] The conductors and insulating and shielding cable materials of high-voltage cables for high-speed railway trains are all made of irradiated or chemically cross-linked polyethylene or polypropylene non-polar polymer materials in the prior art, because the materials are based on polyethylene or polypropylene Material, the basic plastic used in the cable material is crystalline plastic, so the softness of the material is not ideal at normal temperature, and the non-polar polymer plastic used in the material, so the oil resistance of the material still needs to be improved. The conductors of the high-voltage cables for high-speed railway trains currently in the market and the shielding cable materials...
