Description
Изобретение относитс к защите металла от коррозии и может быть использовано в различных отрасл х промышленности .This invention relates to the protection of metal against corrosion and can be used in various industries.
Цель изобретени - повышение эффективности защиты от коррозии, снижение температуры фосфатировани и повышение ударной прочности наносимых лакокрасочных покрытий.The purpose of the invention is to increase the effectiveness of corrosion protection, lowering the temperature of phosphating and increase the impact strength of applied paint coatings.
Состав готов т следующим образом.The composition is prepared as follows.
Раствор дл фосфатировани готов т путем последовательного растворени в воде фосфорной кислоты, окиси цинка , нитрата натри , трехокиси хрома и первичного алифатического спирта нормального строени с числом атомов углерода 2-4.The solution for phosphating is prepared by successively dissolving in water phosphoric acid, zinc oxide, sodium nitrate, chromium trioxide, and a primary aliphatic alcohol of normal structure with 2-4 carbon atoms.
Врем от приготовлени раствора до его применени составл ет 0,5-7 ч. Состав дл фосфатировани нанос т кистью,при обычных температурах на поверхность стали (в том числе на поверхность , покрытую окалиной и ржавчиной ) .The time from preparation of the solution to its application is 0.5-7 hours. The composition for phosphating is applied by brush, at ordinary temperatures, on the surface of the steel (including on the surface covered with scale and rust).
Коррозионную стойкость фосфатных пленок оценивают в камере сол ного тумана . Результаты коррозионных испытаний приведены в таблице.The corrosion resistance of phosphate films is evaluated in a salt fog chamber. The results of corrosion tests are given in the table.
Технико-экономическими преимуществами предлагаемого состава вл ютс повышение эффективности защиты от коррозии, снижение температуры фосфатировани и повышение ударной прочности наносимых пакокрлсочных покрытий.The technical and economic advantages of the proposed composition are an increase in the effectiveness of protection against corrosion, a decrease in the temperature of phosphatization, and an increase in the impact strength of the applied packet covering.
