Description
Изобретение относитс к области получени минеральных пигментов, примен ющихс в лакокрасочной промышленности дл производства эмалей, окраски пластмасс и других целей.The invention relates to the field of the production of mineral pigments used in the paint industry for the production of enamels, the coloring of plastics and other purposes.
Известный способ получени пигмента «марганцова зелена заключаетс в прокаливании при температуре 650-750°С шихты, состо шей из марганцесодержащего соединени , гидрата окиси бари и окислител , с последуюш ,ей промывкой плава водой и сушкой отделенного пигмента.A known method for producing a manganese green pigment is to calcine at a temperature of 650-750 ° C a charge consisting of a manganese-containing compound, barium oxide hydrate and oxidant, followed by washing it with water and drying the separated pigment.
Такой пигмент совершенно не обладает атмосферостойкостью , что объ сн етс присутствием в нем гидрата окиси бари (последнийSuch a pigment is completely weatherproof, which is explained by the presence of barium hydroxide in it (the last
реагирует с углекислым газом воздуха).reacts with carbon dioxide air).
Предлагаемый способ отличаетс от известного тем, что в качестве барийсодержаш;его соединени примен ют сернокислый барий,The proposed method differs from the known one in that barium-containing materials are used, its compounds are applied to barium sulphate,
плав перед промывкой подвергают выш;елачиванию сол ной кислотой, промывку осуществл ют щавелевой кислотой, а полученный пигмент после сушки прокаливают при 800- 850°С.before washing, the melt is subjected to higher hydrochloric acid, washing is carried out with oxalic acid, and the obtained pigment is calcined after drying at 800-850 ° C.
Это позвол ет получить пигмент с повыщенной атмосферостойкостью и интенсивностью .This makes it possible to obtain a pigment with increased weather resistance and intensity.
Сравнительные характеристики пигментов, получаемых по известному и предлагаемомуComparative characteristics of pigments obtained by the known and proposed
способам, приведены в табл.methods are given in table.

Полученный по предлагаемому способуObtained by the proposed method
Не стоек (полное разрушение поверхностного сло накраски наступает через 1-3 мес ца)Not resistant (complete destruction of the surface layer of paint occurs in 1-3 months)
Стоек (разрушение поверхностного сло накраски не наблюдаетс в течение 12 мес цев) Пример. 2 г Мп02, 52 г Ва(1МОз)2 и 31 г BaSO4 смешивают и прокаливают при температуре , например 750°С, в течение 1 час. Полученный нлав заливают 70 мл 18%-ной НС1, провод т выщелачивание в течение 1 час, после чего маточник сливают, а насту полуфабриката заливают 100 мл 0,1%-ного раствора щавелевой кислоты и повтор ют проMijiBKy до отсутстви ионов хлора. Затем насту полуфабриката отфильтровывают, сушат и вторично прокаливают нри температуре 800-850°С в течение 1 час. Пигмент размалывают и просевают. Предмет изобретени Способ получени нигмента «марганцова зелена путем прокаливани шихты, состо щей из марганецсодержащего соединени , окислител и барийсодержащего соединени , промывки полученного нлава и сушки отделенного пигмента, отличающийс тем, что, с целью нридани пигменту повышенной атмосферостойкости , в качестве барийсодержащего соединени нримен ют сернокислый барий , плав перед промывкой подвергают выщелачиванию сол ной кислотой, промывку осуществл ют щавелевой кислотой и полученнь1Й после сушки нигмент подвергают вторичному прокаливанию при температуре 800-850°С.Racks (destruction of the surface layer of paint is not observed for 12 months) Example. 2 g of MnO2, 52 g of Ba (1M2) 2 and 31 g of BaSO4 are mixed and calcined at a temperature of, for example, 750 ° C, for 1 hour. The resulting nlav is poured over 70 ml of 18% HC1, leaching is carried out for 1 hour, after which the mother liquor is drained, and the mixture of the semi-finished product is poured with 100 ml of 0.1% oxalic acid solution and repeated MijiKy until there are no chlorine ions. Then the mixture of the semi-finished product is filtered, dried and calcined again at a temperature of 800-850 ° C for 1 hour. The pigment is ground and sieved. Subject of the invention The process for preparing nigmenta "permanganic greener by calcining batch consisting of a manganese compound oxidant and barium-containing compound, washing the resulting nlava and drying the separated pigment, characterized in that, in order nridani pigment enhanced weatherability as barium-containing compound nrimen dissolved sulphate barium, melting before washing, is leached with hydrochloric acid, washing is carried out with oxalic acid, and the nigment obtained after drying They are secondary calcined at a temperature of 800-850 ° C.
