Problems solved by technology

Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two functions must be guaranteed. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions. Otherwise, the insulator will not play a significant role, and it will damage the service life and operating life of the entire line
[0003] The existing composite insulator umbrella cover material is silicone rubber material, and the mechanical properties need to be improved. Because birds like to eat the composite insulator shed or sheath, which exposes the mandrel and affects the insulation performance of the composite insulator, there is a certain security risks, will cause major economic security losses to the country

Abstract

The invention relates to the technical field of composite insulators, and in particular, relates to a silicone rubber material for a composite insulator and a preparation method of the silicone rubbermaterial. The silicone rubber material for the composite insulator is prepared from the following raw materials in parts by weight: 100 parts of a rubber base material, 30-60 parts of white carbon black, 1-8 parts of hydroxyl silicone oil, 2-10 parts of hydrogen-containing silicone oil, 100-300 parts of active aluminum hydroxide, 2-10 parts of zinc oxide, 0.5-2 parts of a color master batch, 0.5-2 parts of a vulcanizing agent, and 1-5 parts of methyl anthranilate. Under the synergistic effect of all the raw material components, the obtained silicone rubber material is excellent in mechanicalproperty, meanwhile, birds can be prevented from pecking the silicone rubber material, the electrical performance of the product is improved, bruising and reworking are avoided, and the use safety performance and economic value of the product are improved.

Description

technical field [0001] The invention relates to the technical field of composite insulators, in particular to a silicone rubber material for composite insulators and a preparation method thereof. Background technique [0002] A lot of disc-shaped insulators are hung on one end of the high-voltage wire connection tower. It is used to increase the creepage distance. It is usually made of glass or ceramics and is called an insulator. Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two functions must be guaranteed. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions. Otherwise, the insulator will not play a significant role, and it will damage the service life and operating life of the entire line. [0003] The existing composite insulator umbrella cover material is silicone rubber material, and t...
