Problems solved by technology

However, these insulators (ceramic or glass insulators) coated with room temperature vulcanized silicone rubber (RTV) will reduce or lose the hydrophobicity and hydrophobic migration properties of the room temperature vulcanized silicone rubber (RTV) coating due to climate and environmental reasons during use. Decrease the anti-pollution flashover ability of insulators, seriously affecting the safety of power transmission
At present, it is generally used to directly replace room temperature vulcanized silicone rubber (RTV) insulators with reduced anti-pollution flashover capabilities, resulting in environmental pollution and waste of insulating devices

Abstract

The invention discloses a stripping agent special for room-temperature vulcanized silicone rubber for an insulator and a stripping method. The stripping agent is prepared from, by mass, 50-70 parts ofsolvent butanone, 10-30 parts of cosolvent methyl alcohol, 10-20 parts of stripping auxiliary concentrated hydrochloric acid, 5-10 parts of functional auxiliary concentrated sulfuric acid and 2-5 parts of builder ethyl acetate. The stripping agent can effectively strip an RTV coating on the surface of the insulator (glass or ceramic insulator) coated with room temperature vulcanized silicone rubber (RTV) so that the surface of the insulator is recovered to be smooth and flat. Therefore, the effects of recycling and reducing pollution are achieved.

Description

technical field [0001] The invention belongs to the field of electric equipment reuse, and in particular relates to a special stripping agent for room temperature vulcanized silicone rubber for insulators and a stripping method. Background technique [0002] Insulators are the most common insulating devices in power transmission. According to their different insulating materials, they can be divided into ceramic insulators, glass insulators and composite insulators, among which ceramic insulators and glass insulators are more widely used. In some environmentally polluted areas, insulators (ceramic or glass insulators) for power transmission are generally coated with room temperature vulcanized silicone rubber (RTV) coatings to improve the hydrophobicity and hydrophobic migration performance of the insulator surface, thereby improving the flashover of the insulator voltage, reducing the risk of pollution flashover of insulators. However, these insulators (ceramic or glass in...
