Abstract

The invention discloses a silicone rubber fire-proof high-voltage-resistant insulated wire which comprises a conductor and an insulating layer covering the periphery of the conductor. A coating undergoes coating between the conductor and the insulating layer. The coating comprises, by weight parts, 80-120 parts of methacrylic acid silicone rubber, 30-60 parts of white carbon black, 5-15 parts of porcelain powder, 2-8 parts of benzophenone, 3-6 parts of triallyl isocyanurate, 4-8 parts of tensile strength modifier, 2-6 parts of flame retardant, 1-5 parts of magnesium oxide, 4-8 parts of zinc stearate, 1-4 parts of zinc borate, 2-6 parts of iron oxide, 4-8 parts of hydroxyl silicone oil, 1-4 parts of titanium dioxide, 3-8 parts of gas phase aluminum hydroxide, 4-8 parts of fumed silica, 1-5 parts of foaming agent, 2-7 parts of color masterbatch, 1-4 parts of vulcanizing agent, 2-6 parts of platinum catalyst, 3-6 parts of silicone oil and 1-5 parts of low density polyethylene. The obtained wire is good in fire resistance and high voltage resistance.

Description

technical field [0001] The invention relates to the field of wires, in particular to a silicone rubber fire-resistant and high-voltage insulated wire and a preparation method thereof. Background technique [0002] With the frequent occurrence of fire accidents, people's awareness of the fire hazards of wires and cables continues to deepen, and the relevant departments have higher and higher requirements for the performance of wires and cables such as fire resistance and flame retardancy. Due to the characteristics of rapid spread of wire and cable fires, difficulty in fighting, secondary hazards, and long recovery time, it will bring huge losses to the national economy and the lives and properties of the people. Therefore, people have put forward more stringent operating conditions for the fire protection characteristics, safety and reliability of wires and cables. [0003] The fire resistance performance and high voltage resistance performance of electric wires in the prio...
