Abstract
Description
Изобретение относится к области нанесения защитно-декоративных покрытий, а именно для холодного чернения (воронения металлов), и может быть использовано для металлических изделий из стали и чугуна. Покрытие может быть использовано для декоративной отделки любых изделий, полученных методами ковки, чеканки, литья и другими известными способами.The invention relates to the field of applying protective and decorative coatings, namely for cold blackening (metal burnishing), and can be used for metal products from steel and cast iron. The coating can be used for decorative decoration of any products obtained by forging, stamping, casting and other known methods.
В известном уровне техники понятие чернение (воронение) относится к холодной обработке металлов без термической обработки. При этом для обработки применяются специальные растворы.In the prior art, the concept of blackening (burnishing) refers to the cold processing of metals without heat treatment. In this case, special solutions are used for processing.
Состав для чернения наносится на поверхность с образованием плотной пленки на поверхности.The ink composition is applied to the surface to form a dense film on the surface.
Традиционно составы для чернения содержат сульфат меди, соли железа. Среда в составах может быть как кислой, так и щелочной. Составы наносят на поверхность и оставляют на продолжительное время (более чем на 30 минут) для более длительного воздействия в условиях повышенных температуры и влажности.Traditionally, blackening compositions contain copper sulfate, iron salts. The environment in the compositions can be both acidic and alkaline. The compositions are applied to the surface and left for a long time (more than 30 minutes) for a longer exposure in conditions of elevated temperature and humidity.
Слой ржавчины затем обрабатывают водяным паром и удаляют щеткой. Операция повторяется до тех пор, пока не будет достигнут желаемый результат. Нередко приходится наносить средство свыше 10 и даже до 20 раз.The rust layer is then steam treated and removed with a brush. The operation is repeated until the desired result is achieved. Often you have to apply the product over 10 and even up to 20 times.
Время обработки поверхности составом, содержащим сульфат меди, менее 30 минут с получением хорошего результата, а именно 5 сек-120 сек, известно из патента JPS 57101658 (приоритет от 27.06.1982).The surface treatment time of a composition containing copper sulfate is less than 30 minutes to obtain a good result, namely 5 sec-120 sec, it is known from JPS patent 57101658 (priority from 06/27/1982).
При этом поверхность из нержавеющей стали для чернения и защиты от коррозии обрабатывают в две стадии.At the same time, the stainless steel surface is treated in two stages for blackening and corrosion protection.
Первая стадия включает обработку поверхности составом из водного раствора уксусной кислоты, содержащим хлорид и ацетат меди. Состав оставляют на поверхности в течение 5 сек-120 сек для образования медного покрытия на обработанной поверхности, препятствующего коррозии поверхности.The first stage involves surface treatment with a composition of an aqueous solution of acetic acid containing chloride and copper acetate. The composition is left on the surface for 5 sec-120 sec to form a copper coating on the treated surface, preventing corrosion of the surface.
Вторая стадия заключается в чернении обработанной поверхности. На этой стадии поверхность обрабатывают жидкостью, содержащей смесь Se (IV), в частности селенистую кислоту, которая контактирует с медным покрытием на поверхности стали с образованием стойкого черного покрытия.The second stage is to blacken the treated surface. At this stage, the surface is treated with a liquid containing a mixture of Se (IV), in particular selenic acid, which contacts the copper coating on the surface of the steel to form a stable black coating.
Недостатком известного способа является чрезмерная длительность процесса вследствие строго соблюдения поэтапности, следующими друг за другом стадиями.The disadvantage of this method is the excessive duration of the process due to strict observance of the phasing, following each other stages.
В отличие от вышеописанного способа заявленный состав для чернения имеет ряд существенных преимуществ, а именно уменьшение времени на обработку поверхности, при этом обработка металлической поверхности проводится в одну стадию.In contrast to the above method, the claimed composition for blackening has a number of significant advantages, namely, reducing the time for surface treatment, while processing the metal surface is carried out in one stage.
Техническим результатом заявленного изобретения является упрощение технологии обработки за счет проведения процесса в одну стадию. Техническим результатом является также то, что использование заявленного состава (вариантов) также позволяет удалить уже появившиеся признаки коррозии (ржавчину) и одновременно осуществить воронение (чернение) обрабатываемой поверхности из металла (стали или чугуна).The technical result of the claimed invention is the simplification of processing technology by conducting the process in one stage. The technical result is also that the use of the claimed composition (options) also allows you to remove signs of corrosion that have already appeared (rust) and simultaneously burnish (blacken) the treated surface from metal (steel or cast iron).
Состав для чернения с диоксидом селена может включать следующие компоненты, мас.%:The composition for blackening with selenium dioxide may include the following components, wt.%:
Диоксид селена может быть замещен селенистой кислотой.Selenium dioxide may be substituted with selenic acid.
Состав для чернения, включающий селенистую кислоту, мас.%:Composition for blackening, including selenic acid, wt.%:
Состав для чернения получают следующим образом.The composition for blackening is obtained as follows.
I вариант. В реактор загружают 129 г дистиллированной воды, 7,5 г диоксида селена, 9 г меди сернокислой, 4,5 г концентрированной соляной кислоты и перемешивают при комнатной температуре до растворения реагентов.I option. 129 g of distilled water, 7.5 g of selenium dioxide, 9 g of copper sulfate, 4.5 g of concentrated hydrochloric acid are charged into the reactor and stirred at room temperature until the reactants are dissolved.
При нанесении на сталь марки 50А средство придает поверхности черный матовый цвет.When applied to grade 50A steel, the product gives the surface a matte black finish.
II вариант. В реактор загружают 124 г дистиллированной воды, 10 г селенистой кислоты, 12 г меди сернокислой, 4 г концентрированной соляной кислоты и перемешивают при комнатной температуре до растворения реагентов.II option. 124 g of distilled water, 10 g of selenic acid, 12 g of copper sulfate, 4 g of concentrated hydrochloric acid are charged into the reactor and stirred at room temperature until the reactants are dissolved.
Как и при применении состава по примеру 1, при нанесении на сталь марки 50А средство придает поверхности черный матовый цвет.As with the composition of Example 1, when applied to grade 50A steel, the product gives the surface a black matte color.
Наносят средство для чернения на тщательно очищенную и обезжиренную поверхность металла, используя тонкую кисточку, ватную палочку или мягкую впитывающую ткань. Состав наносят тонким слоем, промакивая поверхность до появления интенсивного черного цвета, и дают подсохнуть. Через 3-10 минут смывают избыток средства тонкой струей воды, мягко вытирают поверхность впитывающей тканью и сушат на воздухе. Действие можно повторить несколько раз до достижения желаемой степени чернения. Заявленный состав позволяет обрабатывать любую поверхность готовых изделий из стали и чугуна при температуре +5÷30°С. При этом возможна обработка влажной поверхности.Apply a blackening agent to a thoroughly cleaned and degreased metal surface using a thin brush, cotton swab or a soft absorbent cloth. The composition is applied in a thin layer, blotting the surface until an intense black color appears and allow to dry. After 3-10 minutes, the excess is washed off with a thin stream of water, gently wipe the surface with an absorbent cloth and dried in air. The action can be repeated several times until the desired degree of blackening is achieved. The claimed composition allows you to process any surface of finished products from steel and cast iron at a temperature of + 5 ÷ 30 ° C. In this case, wet surface treatment is possible.
