CATIONIC BITUMEN EMULSION FOR ANTICORROSION PROTECTION OF STEEL Russian patent published in 2014 - IPC C08L95/00 C04B26/26 C09D195/00 C23F11/14 C23F11/16 C23F11/167 

FIELD: chemistry.

SUBSTANCE: invention relates to bitumen emulsions and can be used for the anticorrosion protection of steel and in road building. A cationic bitumen emulsion for the anticorrosion protection of steel, including bitumen, emulsifier KADEM-VT, vat residue of benzene rectification, hydrochloric acid, penazoline K, additionally contains a synergic mixture of corrosion inhibitors from 5,6,7,8-tetrachloroquinozoline, diethyl-S-(6-chlorobenzoxazolinon-2-yl-3-methyl)dithiophosphate, with the following component ratio, wt %: bitumen 55-60; emulsifier KADEM-VT 2.9-4.5; vat residue of benzene rectification 10-11; hydrochloric acid 0.6-0.8; diethyl-S-(6-chlorobenzoxazolinon-2-yl-3-methyl)dithiophosphate 0.3-0.4; 5,6,7,8-tetrachloroquinozoline 0.4-0.5; penazoline K 0.4-0.9; water - the remaining part.

EFFECT: emulsion makes it possible to reduce wear of the road coating and protect the metal surface of moving transport from corrosion.
