Abstract

The invention discloses an algae-removal bacteriostatic silicone rubber insulating material, which comprises vulcanized silicone rubber. The vulcanized silicone rubber contains composite aerogel supporting antimicrobial agent metal / metal ion. A method for preparing the silicone rubber insulating material comprises the following steps: adding the composite aerogel supporting antimicrobial agent metal / metal ion into raw materials for preparation of the vulcanized silicone rubber, mixing and carrying out vulcanization molding to obtain the silicone rubber insulating material. According to the insulating material, growth of microbes on the surface of silicone rubber can be effectively prevented, formation of a bio-film is avoided, and the composite insulating material is prevented from being corroded by microbes.

Description

technical field [0001] The invention relates to electrical insulating materials, in particular to an algae-killing and antibacterial silicone rubber insulating material and a preparation method. Background technique [0002] Silicone rubber materials (mainly referring to high-temperature vulcanized composite materials and room temperature vulcanized composite materials) are widely used in the field of high-voltage external insulation. However, as silicone rubber materials are more widely used in the country and the world, it also exposes various problems in different environments. In Sichuan, Yunnan, Guangxi, Guangdong and other places in my country, algae and fungi have been found to grow on the surface of external insulation equipment to varying degrees. Since algae, fungi, and bacteria themselves belong to microorganisms, when the environment is suitable, their reproduction speed is exponential, and even form symbiotic biofilms. When parasites reproduce in large numbers...
