Embodiment Construction

[0013] A new type of anti-static locomotive cable material, prepared from the following parts by weight (kg) of raw materials: magnesia 3, tin-bismuth alloy powder 6, polypropylene 26, expanded vermiculite 7, sludge 32, zinc sulfate 4, sulfuric acid Ferrous 2, paraffin wax 2.6, rubber accelerator 1.2, organotin stabilizer 2, ethylene propylene copolymer 10, chloroprene rubber 13, polyethylene 58, deionized water.

[0014] The new type of anti-static locomotive cable material is prepared by the following specific steps:

[0015] (1) Stir and mix the expanded vermiculite and sludge, and then use 78% sulfuric acid for acidification. After the acidification is completed, it is added to a pair of rollers to be extruded into a sheet, and then transferred to a rotary kiln for roasting for 2 hours. The temperature is controlled to 200°C, cooled to room temperature and crushed for use;

[0016] (2) Mix zinc sulfate and ferrous sulfate with 15 times the total weight of deionized water to diss...

Abstract

The invention discloses a novel antistatic locomotive cable material. The material is prepared from, by weight, 3-4 parts of magnesia, 6-8 parts of tin-bismuth alloy powder, 26-33 parts of polypropylene, 7-9 parts of expanded vermiculite, 32-36 parts of sludge, 4-5 parts of zinc sulfate, 2-3 parts of ferrous sulfate, 2.6-4 parts of paraffin, 1.2-1.5 parts of rubber accelerator, 2-3 parts of organic tin stabilizer, 10-15 parts of propylene polymer, 13-17 parts of chloroprene rubber, 58-65 parts of polyethylene and a proper amount of deionized water. A locomotive cable is easy to prepare, excellent in performance, environmentally friendly, free of pollution, good in oil resistance, excellent in ageing resistance, good in antistatic capacity, capable of meeting market requirements and wide in potential.

Description

Technical field [0001] The invention relates to the technical field of cable materials, in particular to a new type of anti-static locomotive cable material. Background technique [0002] Polymers are widely used in various fields of production and life due to their low price, light texture, high specific strength, low thermal conductivity and good chemical stability. Most polymers are good electrical insulators with high resistivity and are prone to static electricity, which limits their applications. The harm of anti-static electricity is increasing. For example, it interferes with the normal operation of aircraft radio equipment, affects the operation of aircraft, and the polymer shell of pharmaceutical factory equipment is easy to electrostatically adsorb dust and affects the purity of medicine. In recent years, the national railway transportation has developed rapidly. The control of the system is becoming more and more complex, and there are more and more electrical contro...
