Abstract
The invention discloses an anti-ultraviolet cracking-resistant cable material for a locomotive. The cable material is prepared from, by weight, 2.3-3 parts of triethanolamine borate, 0.3-0.4 part of emulsifier OP-10, 44-49 parts of thermoplastic polyurethane elastomer, 6-8 parts of tin-bismuth alloy powder, 26-33 parts of polypropylene, 5-7 parts of fatty acid, 2-3 parts of microcrystalline wax, 5-6 parts of barium sulfate, 3-5 parts of organic heavy calcium, 6-8 parts of white carbon black, 3-4 parts of potassium titanate crystal whisker, 0.4-0.5 part of cross linking agent TAC, 2-3 OBS organic stabilizer, 28-35 parts of polylactic acid and a proper amount of deionized water. The cable material is high in strength, insulating, tearing-resistant and high in elongation rate, can meet using needs of locomotive cables and is long in service life and worthy of popularization.
Description
technical field [0001] The invention relates to the technical field of cable materials, in particular to an anti-ultraviolet and anti-crack type cable material for locomotives. Background technique [0002] Polymers are widely used in various fields of production and life due to their low price, light texture, high specific strength, small 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. Antistatic hazards are becoming more and more serious, such as interfering with the normal operation of aircraft radio equipment, affecting the operation of aircraft, and the polymer shell of pharmaceutical factory equipment is prone to electrostatic adsorption of dust, affecting the purity of drugs, etc. In recent years, the national railway traffic has developed rapidly, and railway The control of the system is becoming more and more complex, there are ...
