METHOD FOR OBTAINING A WATER-WAX EMULSION TO PROTECT METAL PRODUCTS FROM CORROSION Russian patent published in 2022 - IPC C09D5/08 C08L91/06 C08J3/03 C07C69/26 C09D191/06 

FIELD: water-wax emulsions preparation.

SUBSTANCE: method for preparing water-wax emulsions for preparing compositions for protecting metal products from atmospheric corrosion. The method for obtaining a water-wax emulsion includes mixing ceresin with a surfactant and water, while the product of the interaction of animal fat with diethanolamine and boric acid, taken in a mass ratio of 65:21:14, is used as a surfactant, which is obtained by heating to 170°C for 1 h, ceresin is added, then the resulting mixture is dissolved in xylene and all components are intensively mixed with water until a homogeneous white emulsion is obtained with a content of components, wt. %: ceresin 18.0-23, animal fat, diethanolamine, boric acid in a mass ratio of 65:21:14 4.0-5.0, xylene 12.0-20.0, water up to 100.

EFFECT: expansion of the arsenal of stable anti-corrosion compounds to improve the corrosion resistance of metal products in conditions of high humidity and temperature and allows to increase the reliability of equipment operation, process safety and improve the wettability of metal products by emulsion.
