[0059] The present invention also provides a preparation method for the above cleaning composition for composite insulators with repair function, comprising the following steps:
[0060] Based on the mass of organic acid, 5-10 parts of organic acid, 5-10 parts of alcohol ether solvent, 2-10 parts of ethoxylated polytrisiloxane, 1-5 parts of fluorine-containing surfactant, corrosion inhibitor 1 to 3 parts of antibacterial agent, 2 to 10 parts of bactericidal and antifungal agent, and 60 to 80 parts of water are mixed to obtain a dirt cleaning agent;
[0061] Based on the mass of polydimethylsiloxane containing denaturing groups, 25-35 parts of polydimethylsiloxane containing denaturing groups, 3-8 parts of compound emulsifier, 1-3 parts of dispersing agent The parts are mixed and then heated to obtain a denatured silicone oil mixture;
[0062] Mixing the denatured silicone oil mixture with 60 to 70 parts of water to obtain a denatured silicone oil emulsion;
[0063] The denat...
