Abstract

The invention discloses a silicon rubber composite cable material and a preparation method thereof. The cable material comprises silicon rubber, ethylene propylene rubber, butadiene rubber, polyarylacetylene resin, stearic acid, zinc oxide, sulfur, 2, 4-dichlorobenzoyl peroxide, coupling agents, graphite, accelerants, anti-aging agents, modified fire retardants, 1, 4-cyclohexanedimethanol diglycidyl ether, carbon fibers, white mica and melamine polyphosphate. The modified fire retardants are prepared according to the process including the steps: gelatinizing starch; adding the starch into water; adding nano-sized magnesium oxide, zirconium oxide, iron oxide and carbon nano-tubes; performing ultrasonic treatment, drying, carbonization, crushing and sieving. The preparation method of the silicon rubber composite cable material is simple in process, and the prepared silicon rubber composite cable material is good in heat resistance and aging resistance and excellent in fire resistance.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a silicone rubber composite cable material and a preparation method thereof. Background technique [0002] Wires and cables play an important role in transmitting energy and transmitting information, and have been widely used in various fields. Rubber is one of the important raw materials of cables, and its performance is related to the development of the entire cable industry. In recent years, the number of fire accidents caused by cables has increased year by year. One of the important reasons is that the rubber materials used have poor physical and mechanical properties, heat resistance and flame retardancy, and will burn rapidly in case of fire or fire. Therefore, it is very important for the development of cable materials to improve the physical and mechanical properties and heat and flame resistance of rubber materials used. Contents of the invention [0003] Ba...
