Abstract

The invention discloses a cleaning protective agent for a porcelain bottle of a transformer substation and a preparation method thereof. The cleaning protective agent for the porcelain bottle of the transformer substation comprises the following components in parts by mass: 4-10 parts of fluorosilicone polymer, 90-95 parts of thinner and 0.01-0.04 part of curing agent, wherein the fluorosilicone polymer comprises the following components in parts by mass: 50-80 parts of ethyl acetate, 10-25 parts of prefluor-4-methyl-2-amylene, 5-20 parts of methyl methylacrylate, 2-15 parts of silane coupling agent and 0.1-0.6 part of azodiisobutyronitrile. The preparation method comprises the following steps of: adding the ethyl acetate, the azodiisobutyronitrile, the ethyl methylacrylate, the silane coupling agent and the prefluor-4-methyl-2-amylene to a reaction kettle, refluxing, reacting, cooling to obtain the fluorosilicone polymer, adding the prepared fluorosilicone polymer, the thinner and the curing agent to a stirrer in sequence, and uniformly stirring to obtain the cleaning protective agent for the porcelain bottle of the transformer substation. The preparation method has the advantages of low cost, convenience in operation and high efficiency.

Description

technical field [0001] The invention relates to a protective agent, in particular to a special cleaning and protective agent for substation porcelain vases. The invention also relates to a preparation method of the special cleaning and protecting agent for substation porcelain vases. Background technique [0002] In recent years, due to the good insulation performance and anti-pollution flashover performance (good hydrophobicity and hydrophobic migration) of silicone rubber material products (silicone rubber composite insulators, silicone rubber composite bushings, anti-fouling flashover coatings), electricity has been obtained wide range of applications in the sector. However, because the silicone rubber material itself is easy to be stained with dust, the surface of the (silicone rubber composite insulator, silicone rubber composite bushing, anti-fouling flashover coating) that has been in operation for several years is prone to accumulate thick dirt, which will cause ins...
