Problems solved by technology

[0003] Although the prior art has been reported to be used in cables for high-speed railway trains, the basic materials such as polyethylene or polypropylene used in the prior art lead to softness, high temperature resistance (140°C), oil resistance and resistance to material at room temperature. Poor flammability

Embodiment 1

[0060] Example 1: First take 330 grams of base rubber, knead on a small open mill, add fine materials, stabilizers, anti-aging agents, part of fillers and plasticizers, etc. after fully covering the rolls, add the remaining filler coarse After adding vulcanizing agent and vulcanizing aids to form, the pitch of the rollers of the small machine is reduced, and the rubber is made into thin sheets, and the rubber is made into a triangle bag at least 3 times, and the sheet is about 5mm in size, and then cooled for later use.

Embodiment 2

[0061] Example 2: Put 24 kg of masticated base rubber into the internal mixer for 30 seconds to 1 minute, then add 53.50 kg of compounding agents such as anti-aging agent, stabilizer, plasticizer, filler, etc. except vulcanizing agent , after mixing for about 5 minutes, discharge and press the tablet to open strips and filter the rubber, and then cool the sheet for later use. The thickness of the sheet is about 2mm. After parking for at least 4 hours, weigh 77.50 kg of unsulfurized rubber and put it into the internal mixer for mixing. After refining for about 3 minutes, add 2.5 kg of vulcanizing agent and vulcanizing aid for 30 seconds to 1 minute. Afterwards, the strips are turned and cooled, and the thickness of the strips is 2.00mm, and the width is 180-250mm.

Abstract

The invention provides a cable material for 140 DEG C high-temperature resistant, high-strength and ultra-soft oil-proof rubber elastic body, and a preparation method thereof. The invention is characterized in that the polar ethylene, the vinyl acetate (EVA) and the environmental-friendly high molecular material are taken as the foundational rubber formula, and the corresponding curing system is added with environmental-friendly aluminum hydroxide, boron-zinc flame retardant, calcium or zinc stabilizer, high-temperature resistant silicone oil plasticizer, and the like, therefore, the cable material for the rubber elastic body is formed. The cable material has the characteristics that the cable material is 140 DEG C high-temperature resistant and mineral oil and fuel oil resistant, and is ultra-soft, conforms to the requirement of the railway motor train cable and provides convenience for the users of the railway motor train cable.

Description

technical field [0001] The invention relates to an insulating cable material for cables used in high-speed railway trains, in particular to a high-strength, extra-soft, green and environment-friendly oil-resistant rubber elastic cable material. Background technique [0002] The insulating cable materials for cables used in high-speed railway motor vehicles, the existing technology uses irradiation or chemical cross-linked polyolefin non-polar polymer materials, because the material uses polyethylene or polypropylene as the base material, the cable material uses The base plastic is crystalline plastic, so the softness of the material is not ideal at normal temperature. The material uses non-polar polymer plastic, so the oil resistance of the material still needs to be improved. The insulating cable materials for cables used in high-speed railway motor vehicles currently in the market are used on cables, and the flexibility of the cables is not good, which brings inconvenience...
