Изобретение относитс к получению пигментной двуокиси титана и может быть использовано в лакокрасочной промьгш-. ленности.The invention relates to the production of titanium dioxide pigment and can be used in the paint industry. laziness.
По основному авт.св. № 742449 известен Способ получени пигментной двуокиси титана, включающий термогидролиз .раствора сульфата титанила и аммони с кислотным фактором 1,40-1,55. Продолжительность нагревани смеси до ки- Q пени 1-1,5 ч 11.According to the main auth. No. 742449 is known. A method for producing titanium dioxide pigment dioxide, which includes thermal hydrolysis of a solution of titanyl sulfate and ammonium with an acid factor of 1.40-1.55. Duration of heating the mixture to ki Q pen 1-1.5 h 11.
; Недостатком известного способа вл етс низка фильтруемость суспензии после гидролиза (150-300 ;j;j). Двуокись титана , получающа с по этому способу, ,5 имеет белизну 96,6 усл.ед, разбеливающую способность ниже 1200 усл.ед, маслоемкость 24,5. г/100 г, укрывистость 40 г/м.; The disadvantage of this method is the low filterability of the suspension after hydrolysis (150-300; j; j). Titanium dioxide, which is obtained by this method, 5, has a whiteness of 96.6 used units, a scaling capacity of less than 1,200 used units, an oil absorption of 24.5. g / 100 g, hiding power 40 g / m.
Цель изобретени - улучшение фильт- 20 руемости продукта гидролиза. .The purpose of the invention is to improve the filtration capacity of the hydrolysis product. .
Поставленна цель достигаетс тем, что при термическом гидролизе растворов сульф ата титанила и аммони с киспотньшThe goal is achieved by the fact that during the thermal hydrolysis of sulphate of titanyl and ammonium solutions from
фактором 1,40-1,55, в раствор ввод.. сульфат нинка, железа (н) или алюмини в количестве О,ОО5-0,О15 моль/л.a factor of 1.40-1.55, in the solution of the input .. Nink sulfate, iron (n) or aluminum in the amount of O, OO5-0, O15 mol / l.
Пример. Берут 1 л раствора сульфата титанила и аммони (125 т/л TiO,), ввод т в него PeSO в растворенном состо нии вместе с перевосстановленным титановым раствором до концентрации 10,005 моль/л (по Fe), нагревают до кипени в присутствии зол титановых зародышей (0,5%, по отношению к TiO) И кип т т в,течение 3-х часов при посто кном уровне. Пульпу фильтруют (скорость фильтрации - 350 л/мЯ-ч), твердый остаток промывают, модифицируют и прокаливают до нейтральной реакции продукта (t - 830-850°С). Двуокись титана (122 г) имеет следуюише пигментные свойства: белизна 97,0 усл.ед, разбеливающа .способность 121О усл.ед, маслоемкость 23,4 г/ЮО г, укрывистость . 36,5 г/м. .Example. One liter of titanyl sulphate and ammonium solution (125 t / l TiO,) is taken, PeSO is introduced into it in a dissolved state together with a reconstituted titanium solution to a concentration of 10.005 mol / liter (Fe), heated to boiling in the presence of titanium sol. (0.5%, with respect to TiO) And boil in for 3 hours at a constant level. The pulp is filtered (filtration rate is 350 l / mIH), the solid residue is washed, modified and calcined until the product is neutral (t - 830-850 ° C). Titanium dioxide (122 g) has the following pigment properties: whiteness 97.0 sr. Units, disintegrating ability 121O sr., Oil absorption 23.4 g / 10 g, hiding power. 36.5 g / m .
