Abstract

FIELD: production of metal-oxide coatings by precipitation from solution. SUBSTANCE: method is accomplished by application of film-forming coating from a solution containing alkoxide of metal and other compounds with subsequent drying and thermal treatment in three variants. According to first variant the solution contains alkoxide of metal of general formula R-OM, where M-Ti, Zr, Sn, V, R-alkyl C-C,, acetic or propionic acid at molar ratio alkoxide: acid equal to 1:1, and ammonium chloride - 0.1 to 0.5 mass percent of the total mass of alkoxide. According to the second variant the solution contains alkoxide of metal indicated in the first variant, ammonium chloride of the same amount, and acetate or propionate of metal of groups I-VIII at molar ratio alkoxide: carboxylate equal to 1:1. According to the third variant the solution contains the same components as in the first variant and additionally chloride or nitrite of metal of groups I-VIII at molar ratio alkoxide:salt:acid equal to 1:1:2. Isopropyl alcohol n-butyl acetate, methyl ethylene glycol, tetrahydrofuran, ethylcellosolv, etc. are used as solvent. The solution is kept for a long time in contact with air, and for an unlimited long time - in a sealed closed container. Due to the increase of the time of solution "life", it becomes possible to obtain a qualitative uniform coating on large areas, for example, on a sheet having an area of 2.5x1.6 m. The temperature of thermal treatment makes up 200 to 350 C. EFFECT: improved method.

Изобретение относится к области получения металлооксидных покрытий осаждением из раствора. Цель изобретения - улучшение технологичности способа и обеспечение получения качественного равнотолщинного покрытия на поверхностях большого формата. Способ осуществляется путем нанесения пленкообразующего покрытия из раствора, содержащего алкоксид металла и другие соединения, с последующей сушкой и термообработкой в трех вариантах. По первому варианту раствор содержит алкоксид металла общей формулы R - ОМ, где М - Ti, Zr, Sn, V, R - алкил С2 - С4, уксусную или пропионовую кислоту при мольном соотношении алкоксид : кислота, равном 1 : 1, и хлорид аммония в количестве 0,1 - 0,5 мас. % от общей массы алкоксида. По второму варианту раствор содержит алкоксид металла, указанный в первом варианте, хлорид аммония в том же количестве и ацетат или пропионат металла I - VIII групп при мольном соотношении алкоксид : карбоксилат, равном 1 : 1. По третьему варианту раствор содержит те же компоненты, что и в первом варианте, и дополнительно хлорид или нитрат металла I - VIII групп при мольном соотношении алкоксид : соль : кислота, равном 1 : 1 : 2. В качестве растворителя используют изопропиловый спирт, бутилацетат, метиловый эфир этиленгликоля, тетрагидрофуран, этилцеллозольв и др. Раствор хранится в течение длительного времени при контакте с воздухом, а в герметично закрытой таре - неограниченно долго. За счет увеличения времени "жизни" раствора возможно получение качественного равномерного покрытия на больших площадях, например на листе площадью 2,5 • 1,6 м. Температура термообработки составляет 200 - 350oС.The invention relates to the field of producing metal oxide coatings by solution precipitation. The purpose of the invention is the improvement of the processability of the method and the provision of high-quality uniform-thickness coating on large-format surfaces. The method is carried out by applying a film-forming coating from a solution containing a metal alkoxide and other compounds, followed by drying and heat treatment in three versions. According to the first embodiment, the solution contains a metal alkoxide of the general formula R — OM, where M is Ti, Zr, Sn, V, R is C 2 -C 4 alkyl, acetic or propionic acid with an alkoxide: acid molar ratio of 1: 1, and ammonium chloride in an amount of 0.1 to 0.5 wt. % of the total mass of alkoxide. According to the second variant, the solution contains the metal alkoxide indicated in the first variant, the same amount of ammonium chloride and metal acetate or propionate of groups I - VIII with an alkoxide: carboxylate molar ratio of 1: 1. In the third variant, the solution contains the same components as and in the first embodiment, and additionally a metal chloride or nitrate of groups I-VIII with an alkoxide: salt: acid molar ratio of 1: 1: 2. Isopropyl alcohol, butyl acetate, ethylene glycol methyl ether, tetrahydrofuran, ethyl cello are used as a solvent . OLVIA etc. The solution is stored for a long time in contact with air, and in a hermetically sealed container - indefinitely. By increasing the "life" time of the solution, it is possible to obtain a high-quality uniform coating over large areas, for example, on a sheet with an area of 2.5 • 1.6 m. The heat treatment temperature is 200 - 350 o C.
