Изобретение относитс к химическому окрашиванию металлов.This invention relates to the chemical staining of metals.
Известен раствор дл химического окрашивани цветных металлов, содержащий гидроокись ш,елочного металла и пертиосоединение.A known solution for the chemical staining of non-ferrous metals, containing hydroxide, a spruce metal and a perto-compound.
Предложенный раствор отличаетс от известного тем, что в качестве пертиосоединени использована изопертиодианова кислота при определенном соотношении компонентов. Это способствует расширению цветовой гаммы получаемых покрытий.The proposed solution differs from the known one in that isoperthiodianic acid is used as the perthio compound at a certain ratio of components. This contributes to the expansion of the color range of the resulting coatings.
Предложенный раствор содержит, г/л: Гидроокись ш,елочного металла 10-20 Изопертиоцианова кислота2-5The proposed solution contains, g / l: Hydroxide w, Christmas tree metal 10-20 Isopertiocyanovy acid2-5

-продукт нейтрализации сточных вод коксохимического производства - вл етс дефицитным материалом.—product of neutralizing wastewater from coke-chemical production — is a deficient material.
Предложенный раствор пригоден дл окрашивани серебра и меди. Процесс окрашивани провод т при 40-60°С.The proposed solution is suitable for dyeing silver and copper. The dyeing process is carried out at 40-60 ° C.
При обработке серебра в указанном растворе в течение 10-60 с получают пленки вначале бордово-коричневого, затем сине-фиолетового цвета. При выдержке в растворе в течение 1,5-3 мин получают черные пленки.When silver is processed in this solution for 10–60 s, films are obtained first in maroon-brown, then blue-violet. When kept in solution for 1.5-3 minutes, black films are obtained.
Дл получени аналогичных цветов на меди врем обработки раствором необходимо увеличить приблизительно в два раза.To obtain similar colors on copper, the treatment time with the solution must be approximately doubled.
Дл приготовлени раствора едкий натр или едкое кали раствор ют в дистиллированной воде, подогревают до 60°С, после чего ввод т изопертиоциановую кислоту.To prepare the solution, caustic soda or caustic potassium is dissolved in distilled water, heated to 60 ° C, after which isoperothiocyanic acid is added.
