Изобретение относитс  к способам получени  металлополимерных покрытнп методом электроосаждени .This invention relates to methods for producing metal-polymer coatings by electrodeposition.

Известные способы электролитического получени  металлополимерных покрытий па основе солей цинка и аминоальдегидных смол не обеспечивают получени  покрытий с высокими защитными свойствами.The known methods for the electrolytic production of metal-polymer coatings on a basis of zinc salts and amino-aldehyde resins do not provide coatings with high protective properties.

Дл  улучшени  защитных свойств покрытий предлагаетс  в качестве полимера использовать алифатические полиамиды, а нропесс осаждени  вести при рИ 1-б и плотности тока 0,5-5,0 а/дн из ванны с нолимером конпентрациеП 20-200 г/л и солью цинка - 50-300 г/л.To improve the protective properties of coatings, it is proposed to use aliphatic polyamides as a polymer, and the deposition of lead deposition at pI 1-b and current density of 0.5-5.0 a / day from a bath with a polymer concentration of 20-200 g / l and zinc salt 50-300 g / l.

Режимы электроосаждени  и свойства покрытий представлены в таблице.The modes of electrodeposition and the properties of the coatings are presented in the table.

Коррозионна  стойкость покрытий, полученных но предлагаемому способу, в 2-3 раза превосходит коррозионную стойкость покрытий , полученных известным способом. 3 Предмет изобретени  Способ получени  металлополимерных покрытий путем электроосаждепи  из ванны, содержащей соль цин:ка и азотсодержащий 5 полимер, отличающийс  тем, что, с целью 4 улучшени  защитных свойств покрыти , в качестве полимера используют алифатические полиамиды, а процесс электроосаждени  ведут из ванны с концентрацией полимера 20-200 г/л и соли цинка 50-300 г/л при рН ванны 1-6 и плотности тока 0,5-5,0 а/дм.The corrosion resistance of the coatings obtained by the proposed method is 2-3 times greater than the corrosion resistance of coatings obtained in a known manner. 3 The subject of the invention. A method for producing metal-polymer coatings by electroplating from a bath containing a salt of zinc: ca and a nitrogen-containing 5 polymer. polymer 20-200 g / l and zinc salts 50-300 g / l at a pH of 1-6 bath and current density 0.5-5.0 a / dm.
