High-abrasion-resistance, halogen-free and flame-retardant insulation material for thin-wall locomotive cable

Abstract

The invention discloses a high-abrasion-resistance, halogen-free and flame-retardant insulation material for a thin-wall locomotive cable. The high-abrasion-resistance, halogen-free and flame-retardant insulation material is prepared from, by weight, 10-13 parts of water magnesium powder, 3.2-4 parts of polyphosphoric acid, 0.9-1.4 parts of lauryl amine, 6-8 parts of tin-bismuth alloy powder, 26-33 parts of polypropylene, 14-16 parts of carbon fibers, 17-23 parts of ultra-high molecular weight polyethylene, 0.2-0.4 part of an antioxidant 1010, 4.6-5 parts of antimonous oxide, 0.2-0.4 part of aluminum stearate, 43-50 parts of polyamide 6, a proper amount of absolute ethyl alcohol, a proper amount of xylene and a proper amount of deionized water. The high-abrasion-resistance, halogen-free and flame-retardant insulation material has the advantages of being prominent in abrasion resistance, high in mechanical strength, excellent in flame retardant property, low in smoke, nontoxic, good in insulation performance and the like, and is simple in production process, wide in raw material source, low in cost and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high wear-resistant halogen-free flame-retardant insulating material for thin-walled locomotive cables. 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...

Problems solved by technology

Although the present invention can solve the requirements of cable conduction and antistatic, etc., with the development of locomotive technology, the requirements for the laying environment and performance of cables are getting higher and higher, and the simple single performance can no longer meet the market demand. The present invention is here Based on the improvement, in order to achieve the characteristics of good bending resistance, fire and flame retardant, green environmental protection, aging resistance, etc., so that it can meet the requirements for the use of cables in railway engineering
