FIELD: metallurgy.
SUBSTANCE: invention relates to the anticorrosive protection of items made of ferrous alloys (steel, cast iron). The protective compound for autodeposition on the surface of ferrous alloy items comprises, weight %: primer ВКЧ -0207 on the basis of a solution in isopropyl solution and diacetone alcohol of partial ester maleinized 1.4- cis-polybutadiene mixed with esterified ethyl alcohol, resyl carbonic acids of bisphenol A, with an addition of the antioxidant being ionol 14-16, 25% of aqueous ammonia 0.45-0.55, isopropyl alcohol 32.93- 33.73, water 50.54-51.77.
EFFECT: obtaining of a protective compound not containing highly toxic components as well as thin film on the surface of ferrous alloy items with reduction of the varnish-containing КЧ-0125 component.
