Abstract

The invention relates to a preparation method of a silicone rubber cleaning repair agent, and belongs to the technical field of cleaning. Borax, lanthanum nitrate, a proper modifier and a modificationtechnology are used for preparing a surface-modified nanometer lanthanum borate filler, titanium dioxide sol is prepared through a sol-gel method, by combining with silicone rubber, fluoro alkylsilane and a composite solvent, the silicone rubber cleaning repair agent is prepared; siloxane with reaction activity groups can chemically react with hydroxide radicals in titanium dioxide under the specific condition to form a silane chain, a layer of thin film with the molecular thickness is formed on the surfaces of micropores, the thin film is firmly adsorbed on the surface of silicone rubber, anorganosilicone compound is subjected to a self-condensation reaction under the certain temperature to generate polysiloxane, along with conducting of the reaction, straight chains are changed into areticular structure of branched chains and crosslinks, and the generated firm reticular siloxane thin film has good hydrophobicity and has very low surface tension and can be evenly distributed on thesilicone rubber wall.

Description

technical field [0001] The invention relates to a preparation method of a silicone rubber cleaning and repairing agent, belonging to the technical field of cleaning. Background technique [0002] Silicone rubber composite insulators and glass and porcelain insulators coated with RTV silicone rubber have excellent pollution flashover resistance and can effectively prevent pollution flashover accidents. At present, in heavily polluted areas, well-designed and manufactured composite insulators and glass and porcelain insulators coated with high-quality RTV silicone rubber have more than 20 years of safe operation records and are still in use. However, under the double influence of the electric field and the performance of the silicone rubber material, composite insulators in operation and RTV-coated porcelain and glass insulators will accumulate a large amount of dust on the surface in a short period of time, affecting the appearance of electrical equipment. In addition, with ...
