Abstract

The invention discloses a chloroprene rubber composition for cables and a manufacturing method thereof, which comprises the following raw materials: chloroprene rubber, chlorinated rubber, magnesium oxide, zinc oxide, organic fiber, fumed white carbon black, carbon black, Antiaging agent, accelerator, solid lubricant, filler. In the present invention, chlorinated rubber and chloroprene rubber are used together, and the cold resistance, low temperature flexibility and other properties of chloroprene rubber are improved through formula adjustment and process improvement, and gas phase white carbon black is added to reduce the effect, which is good but relatively expensive. The amount of solid lubricant molybdenum disulfide improves the processing performance and is suitable for the manufacture of cable outer sheaths.

Description

technical field [0001] The invention relates to the technical field of cable sheath materials, in particular to a neoprene composition for cables and a manufacturing method thereof. Background technique [0002] Neoprene has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, and chemical reagent resistance. It has high tensile strength, elongation and reversible crystallinity, and good adhesion. Aging resistance and heat resistance. Excellent oil and chemical resistance. Weather resistance and ozone aging resistance are second only to ethylene propylene rubber and butyl rubber. The heat resistance is equivalent to that of nitrile rubber, the decomposition temperature is 230-260°C, the short-term resistance is 120-150°C, and it can be used for a long time at 80-100°C. It has certain flame retardancy. Oil resistance is second only to nitrile rubber. Good resistance ...
