PROTECTIVE POLYMER FILM FOR CORROSION PROTECTION OF VEHICLE METALS Russian patent published in 2016 - IPC C09D5/08 C09D101/00 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions for anti-corrosion coatings, particularly to polymer coatings based on cellulose lacquer, and is intended for protection of metals of vehicle. Protective polymer film for corrosion protecting of vehicle metal, containing acetone, butyl acetate, additionally contains cellulose lacquer and liquid polyisobutylene, taken in ratio 2:1 respectively, with ratio of components 300 ml cellulose lacquer, 150 ml polyisobutylene, diluted with 50 ml of water, after which produced mixture is boiled for 5 hours, then solution is mixed with 10 ml of acetone or chlorodiphenyl and 20 ml of butyl acetate, obtained compound is boiled for 10 hours.

EFFECT: invention enables to reduce costs for production of anticorrosive coatings, increases adhesion and, as a result, quality of coating, simplifies technology and reduces labour intensity of coating application.
