Недостатком данного состава является появление коррозии при снятии оксидов железа и меди этим составом. The disadvantage of this composition is the appearance of corrosion during the removal of iron and copper oxides by this composition.
Известен также состав, применяемый для снятия и удаления оксидов с металлической поверхности и содержащий водный раствор ортофосфорной кислоты, нефтяной дистиллят, не ионное моющее средство, нефтяной сульфонат и ингибитор (Патент Великобритании N 1142845, кл.

Also known is a composition used to remove and remove oxides from a metal surface and containing an aqueous solution of phosphoric acid, a petroleum distillate, a non-ionic detergent, petroleum sulfonate and an inhibitor (UK Patent N 1142845, CL 23
Недостатком прототипа является растрав металлической поверхности. The disadvantage of the prototype is the raster of a metal surface.
Задачей изобретения является получение состава для снятия и удаления оксидов с металлической поверхности с повышенными ингибирующими свойствами. The objective of the invention is to obtain a composition for removing and removing oxides from a metal surface with enhanced inhibitory properties.
Поставленная задача решается использованием состава для снятия и удаления оксидов с металлической поверхности, содержащего ортофосфорную кислоту, антикоррозионное поверхностно-активное вещество и воду и дополнительно оксид цинка и бутиловый спирт (бутанол-1). В качестве антикоррозионного поверхностно-активного вещества состав содержит "Алкамон ДСУ" общей формулы:

Вода - Остальное
"Алкамон ДСУ" представляет собой отход производства, который известен в текстильной промышленности в качестве аппретирующего средства, смягчителя, антистатика и эмульгатора (Абрамзон А. Справочник поверхностно-активных веществ, Л. , Химия, 1979, с. 294), и его использование в предлагаемом составе увеличивает время последействия.The problem is solved by using a composition for removing and removing oxides from a metal surface containing phosphoric acid, an anticorrosive surfactant and water, and additionally zinc oxide and butyl alcohol (butanol-1). As an anti-corrosive surfactant, the composition contains "Alkamon DSU" of the general formula:
in the following ratio of components, wt.%:
Phosphoric acid - 37.0 - 40.0
Butyl alcohol (butanol-1) - 2.5 - 3.0
Zinc oxide - 5.5-6.0
"Alkamon DSU" - 5.0 - 5.5
Water - Else
"Alkamon DSU" is a waste product that is known in the textile industry as a sizing agent, softener, antistatic agent and emulsifier (Abramzon A. Handbook of surface-active substances, L., Chemistry, 1979, S. 294), and its use in the proposed composition increases the aftereffect.
В таблицах 1-3 приведены результаты испытания образцов предлагаемым и известным составами. В опытах оценивали время последействия ингибированных композиций (tn).Tables 1-3 show the test results of the samples of the proposed and known compositions. In the experiments, the aftereffect time of the inhibited compositions (t n ) was evaluated.
Для этого образцы, отработанные в течение 24 часов в ингибированных и неингибированных композициях, помещали в камеру солевого тумана (3% NaCl, 298K) и с помощью микроскопа ПМТ-3 оценивали время до появления первых следов коррозии - tn, ч.For this purpose, samples worked out for 24 hours in inhibited and non-inhibited compositions were placed in a salt spray chamber (3% NaCl, 298K) and the time until the first signs of corrosion was observed using a PMT-3 microscope was t n , h.
В таблице 4 приведены сравнительные характеристики ингибиторов этилентиомочевины и "Алкамона ДСУ" на изменение времени последействия. Table 4 shows the comparative characteristics of the inhibitors of ethylethiourea and "Alkamona DSU" to change the aftereffect time.
Из данных таблицы 4 следует, что после обработки металлической поверхности в предлагаемом составе поверхность образцов в течение нескольких суток в жестких коррозионных условиях сохраняет свою пассивность. Время последействия новой композиции в 1,5 раза для меди, в 2,5 для алюминия и в 10,7 раза для стали 08 КП выше, чем после обработки в известном составе с этилентиомочевиной. Сведения, подтверждающие возможность осуществления изобретения. From the data of table 4 it follows that after processing the metal surface in the proposed composition, the surface of the samples for several days in severe corrosion conditions remains passive. The aftereffect of the new composition is 1.5 times for copper, 2.5 for aluminum and 10.7 times for steel 08 KP higher than after treatment in a known composition with ethylene thiourea. Information confirming the possibility of carrying out the invention.
Предлагаемый состав готовят смешением компонентов в любой последовательности, перемешиванием при температуре 291-298K. "Алкамон ДСУ", взятый в качестве антикоррозионного поверхностно-активного вещества в предлагаемый состав для снятия и удаления оксидов с металлической поверхности, представляет собой легкоплавкую густую жидкость, устойчивую к повышенным температурам и длительному хранению от желтого до темно-коричневого цвета. "Алкамон ДСУ" растворим в спиртах, бензоле, уайт-спирте, четыреххлористом углероде. "Алкамон ДСУ" - умеренно токсичное вещество 3 класса опасности (ГОСТ 12.1.007-76). The proposed composition is prepared by mixing the components in any sequence, stirring at a temperature of 291-298K. "Alkamon DSU", taken as an anti-corrosion surfactant in the proposed composition for removing and removing oxides from a metal surface, is a low-melting, thick liquid that is resistant to elevated temperatures and long-term storage from yellow to dark brown. "Alkamon DSU" is soluble in alcohols, benzene, white alcohol, carbon tetrachloride. "Alkamon DSU" is a moderately toxic substance of hazard class 3 (GOST 12.1.007-76).
Пример. Ингибиторное действие композиции предлагаемой и известной проверяли методами гравиметрических измерений. Объектами для исследования служили прямоугольные образцы пластинок из стали СТ.08.КП, меди и алюминия. Подготовка образцов для исследования включает шлифование на круге с использованием наждачных бумаг с уменьшающимся размером зерна (вплоть до микронной), обезжиривание поверхности венской известью, промывку дистиллированной водой, декапирование в HCl (1:1) в течение 20-30 с, промывку дистиллированной водой и высушивание фильтровальной бумагой. Example. The inhibitory effect of the composition of the proposed and known was checked by gravimetric measurements. The objects of study were rectangular samples of plates made of steel ST.08.KP, copper and aluminum. Preparation of samples for research includes grinding on a wheel using emery papers with decreasing grain size (up to micron size), degreasing the surface with Viennese lime, washing with distilled water, decapitation in HCl (1: 1) for 20-30 s, washing with distilled water and drying with filter paper.
Измерения потери массы образцов проводили с точностью до 0,0001 г. Расчет скорости коррозии металла под действием композиции (K), защитное действие ингибирующей добавки (Z) и ингибиторный эффект (γ) осуществляли по формулам:

Z = [(K0-K1)/K1]•100%
γ = Ko/K1
где S - площадь образца, м2 (S = 0,0012 м2);
t - время испытания, ч (t=24 ч);
K0 и K1 - скорость коррозии металла в неингибированной и ингибированной композициях, г/м2•ч;
Δm = mo-m1; m0, m1 - масса образца до и после опыта, г.Measurement of the weight loss of the samples was carried out with an accuracy of 0.0001 g. Calculation of the corrosion rate of the metal under the action of the composition (K), the protective effect of the inhibitory additive (Z) and the inhibitory effect (γ) were carried out according to the formulas:
K = Δm / S • t
Z = [(K 0 -K 1 ) / K 1 ] • 100%
γ = K o / K 1
where S is the sample area, m 2 (S = 0.0012 m 2 );
t is the test time, h (t = 24 h);
K 0 and K 1 - metal corrosion rate in uninhibited and inhibited compositions, g / m 2 • h;
Δm = m o -m 1 ; m 0 , m 1 - sample mass before and after the experiment, g.
Результаты величин K1, Z и γ для известной и предлагаемой композиций приведены в табл. 5.The results of the values of K 1 , Z and γ for the known and proposed compositions are given in table. 5.
