SEALING LIQUID Russian patent published in 2022 - IPC C09K3/10 C09K3/12 C08L91/00 C08K5/12 C08K5/13 

FIELD: sealing technology.

SUBSTANCE: invention relates to sealing liquids (non-drying anaerobic sealants) designed to protect against corrosion of accumulator tanks of hot water supply of power plants and the water contained in them from oxygen saturation of the air. A sealing liquid containing, wt. %: high molecular weight polyisobutylene with a molecular weight of 18-20⋅10⁴, 3,5-3,6; tall oil fatty acids modified with chlorophyll derivatives, 5.0-5.5; 4-methylene-bis-(2,6-di-tert-butylphenol), 0.3-0.5; oleic condensation product acids with diethanolamine and boric acid neutralized with a solution of potassium hydroxide, 0.3-0.5; synthetic ether of dibasic acids, 3.0-5.0; and petroleum oil with kinematic viscosity at 50°C of 12-50 mm²/s, the rest up to 100.

EFFECT: proposed sealing liquid has high thermal–oxidative stability, protective and demulsifying properties, which leads to an increase in its service life in hot water storage tanks.
