Problems solved by technology

[0003] The power cables used in buildings have very strict requirements on their flame retardancy. Because the heat generated by the resistance of the cable itself is very large during the transmission of electricity, the requirements for the flame retardancy and heat resistance of the cables are very high; The environment of the construction site is complex, and the cable rubber should have high-strength performance to avoid the cable from being easily damaged due to insufficient strength. The cable rubber material used in ordinary cables cannot meet the performance requirements of the cable rubber material in the construction environment.

Abstract

The invention discloses a building power cable rubber material, and a preparation method thereof. According to the preparation method, silicone rubber and chlorinated polyethylene are subjected to plasticating so as to obtain plasticated rubber; zinc oxide, magnesium oxide, stearic acid, polyisobutylene, zinc methacrylate, and boric acid are added into the plasticated rubber, and an obtained mixture is subjected to first mixing so as to obtain a first mixed rubber compound; white carbon black and calcined clay are added into the first mixed rubber compound for second mixing so as to obtain a second mixed rubber compound; vulcanizing agent DCP, vulcanizing auxiliary agent TMPTMA, anti-aging agent RD, a coupling agent, Sb2O3, chlorinated paraffin, and Mg(OH)2 are added into the second mixed rubber compound for third mixing so as to obtain a third mixed rubber compound; the third mixed rubber compound is cooled so as to obtain the building power cable rubber material which possesses high strength and flame resistance.

Description

technical field [0001] The invention relates to the technical field of cable rubber materials, in particular to a cable rubber material for building electric power and a preparation method thereof. Background technique [0002] At present, power cables are cables used to transmit and distribute electric energy. Power cables used in construction have high requirements on the flame retardancy, heat resistance and aging resistance of cables. Power cables are generally composed of conductor cores, insulating layers, shielding layers, and protective layers. The insulating layer is to electrically isolate the cores from the ground and cores of different phases to ensure power transmission. It is a power cable structure. An indispensable component, the performance of the insulation layer has a great impact on the overall performance of the cable, which is directly related to whether the cable operates normally. The insulating layer can be made of rubber material, commonly used rub...
