Description
Vynález se týká způsobu výroby vysoce koncentrovaného modifikovaného sólu saténové běloby se zlepšenými nátěrovými vlastnostmi. Saténová běloba se vyrábí jak je známo tím, že se k suspensi hašeného vápna přidává za míchání roztok, síranu hlinitého. Probíhá exotermní reakce, při které výsledný produkt, saténová běloba, uváděná ale i jako sulfohlinitan vápenatý vzniká podle následující rovnice:The present invention relates to a process for the production of highly concentrated, modified satin white sol with improved coating properties. Satin white is produced as known by adding an aluminum sulfate solution to the slaked lime slurry with stirring. An exothermic reaction takes place in which the resulting product, satin white, also referred to as calcium sulfoaluminate, is formed according to the following equation:
'6 Ca(OH)2 + Al2(SO4)3 + 25 H2O->6 Ca (OH) 2 + Al 2 (SO 4) 3 + 25 H 2 O->
CaO . AI2O3 . 3 CaSCh . 31 H2OCaO. AI2O3. 3 CaSCh. 31 H2O
Všeobecně se pracuje při velmi malé koncentraci,' takže na .konci je k dispozici suspense saténové běloby s 10 až 12 % sušiny. Tato suspense se zahustí v kalolisech, čímž se získá pasta s obsahem sušiny 22 až 25 °/o. Tato pasta se opět zkapalní přídavkem dispergačních prostředků, Jako dispergační prostředky jsou známy citrany alkalických kovů, sírany, sodné sole oxykarboxylových kyselin, polyakrylany alkalických kovů, směsi citranů alkalických kovů a síranů alkalických kovů, proteiny, gumy, deriváty škrobů a karboxymetylcelulosa nebo její sole.Generally, the process is carried out at a very low concentration, so that at the end a slurry of satin white with 10-12% solids is available. This suspension is concentrated in filter presses to give a paste with a dry matter content of 22-25%. This paste is again liquefied by the addition of dispersants. Alkali metal citrates, sulphates, sodium oxycarboxylic acids, alkali metal polyacrylanes, mixtures of alkali metal citrates and alkali metal sulphates, proteins, gums, starch derivatives and carboxymethylcellulose or salts thereof are known as dispersants.
Tento způsob má ten nedostatek, že se v dodatečném pracovním stupni musí pro použití odstraňovat ze suspense přebytečná voda. Proto byl vyvinut způsob, při kterém se srážecí reakce provádí při vyšší koncentraci, takže suspense je po přídavku dispergačního činidla přímo použitelná. Podle tohoto známého způsobu se k vápennému mléku s asi 20 % hydroxidu vápenatého (Ca(OH)2) přidává za mohutného míchání 25% roztok síranu hlinitého. Potom se. ihned přidá do srážecího reaktoru dispergační činidlo a dále se míchá.This method has the drawback that in the additional process step excess water must be removed from the suspension for use. Therefore, a process has been developed in which the precipitation reaction is carried out at a higher concentration so that the suspension is directly usable after the addition of a dispersant. According to this known method, a 25% aluminum sulphate solution is added to the lime milk with about 20% calcium hydroxide (Ca (OH) 2) with vigorous stirring. Then. immediately dispersing agent is added to the precipitation reactor and further stirred.
Také tento způsob má nedostatek, který spočívá v tom, že se pro zabránění vzrůstu viskczity musí během srážecí reakce udržovat vysoký smykový gradient. Toto podmiňuje použití vysoko výkonných míchadel a velkou spotřebu energie. Kromě toho lpí na obou těchto způsobech ten nedostatek, že se pro snížení viskozity suspense saténově běloby musí používat drahé chemikálie.This method also has the drawback that a high shear gradient must be maintained during the precipitation reaction to prevent the viscosity from rising. This requires the use of high-performance agitators and high energy consumption. In addition, there is a drawback in both processes that expensive chemicals must be used to reduce the viscosity of the satin white suspension.
Vynález si klade za základní úlohu, vyvinout způsob tak, aby se srážení saténové běloby provádělo při koncentraci, která odpovídá koncentraci pasty, aniž by během srážení došlo k zahuštění suspense. Bylo zjištěno, že se úloha vyřeší způsobem výroby vysoce koncentrovaného sólu saténové běloby se zlepšenými nátěrovými vlastnostmi podle vynálezu, jehož podstata spočívá v tom, že se k vápennému mléku před nebo během přidávání síranu hlinitého přidá kyselina mléčná v množství 3 až 20 % hmotnostních vztaženo na kysličník vápenatý a udrží se molár19 6 6 4 2 ní poměr hydroxidu vápenatého k síranu hlinitému v poměru 6,5 :1 až 8 :1.1 Pomocí vynálezu je možné vyrobiti suspensi saténové běloby s obsahem pevných látek 22 až 25 % (sušina při 105 °Cj, která je málo viskózní. Nadto použití této suspense saténové běloby vede ke zlepšení nátěrové kvality s ohledem na hladkost, lesk a povrchovou pevnost.SUMMARY OF THE INVENTION It is an object of the present invention to provide a method such that the precipitation of satin white is carried out at a concentration corresponding to the paste concentration without the suspension being thickened during precipitation. It has been found that the problem is solved by a process for producing a highly concentrated satin white sol with improved coating properties according to the invention, which comprises adding to the lime milk before or during the addition of aluminum sulfate lactic acid in an amount of 3 to 20% by weight The calcium hydroxide / aluminum sulphate ratio in the ratio of 6.5: 1 to 8: 1.1 was maintained in a ratio of 6.5: 1 to 8: 1.1. With the present invention, it is possible to produce a slurry of satin white with a solids content of 22 to 25%. Furthermore, the use of this satin white suspension leads to an improvement in the coating quality with regard to smoothness, gloss and surface strength.
Vynález bude dále vysvětlen na jednom příkladu provedení.The invention will be further elucidated on one embodiment.
Výroba suspense saténové běloby: .Manufacture of satin white suspension:.
Do míchačky se dalo 133,6 kg vápenného mléka s 15,0 % hmotnostními obsahu kysličníku vápenatého. Za míchání se přidalo 2,27 kg kyseliny mléčné. Potom se pomalu přidávalo 71 kg síranu hlinitého měrné hmotnostiThe mixer was charged with 133.6 kg of lime milk with a 15.0% calcium oxide content. 2.27 kg of lactic acid were added with stirring. Thereafter, 71 kg of specific gravity aluminum sulfate was added slowly
I, 28 kg/dm3.' Po dvacetiminutovém míchání se suspense čistila pomocí síta. Měla parametry uvedené v tabulce 1. Je možné seznati, že suspense sama má i pří nízkém smykovém gradientu viskozitu, která dovoluje, aby byla tekutá.I, 28 kg / dm 3. ' After stirring for 20 minutes, the suspension was purified by sieving. It had the parameters listed in Table 1. It can be seen that the suspension itself has a viscosity even at a low shear gradient which allows it to be fluid.
Výroba nátěrové hmoty:Paint production:
40,7 kg suspense saténové běloby bylo předloženo do míchačky. Do této suspense bylo vmícháno 0,4 litru 45% roztoku hydroxidu sodného a nasypáno 2,8 kg kaseinu. Po krátkodobém míchání bylo přidáno40.7 kg of a satin white suspension was introduced into a mixer. 0.4 liter of 45% sodium hydroxide solution was mixed into this suspension and 2.8 kg of casein was added. After brief stirring, was added

Nátěrová hmota byla nanesena v množství 21 g/m2 na natíracím stroji pomocí kombinace sfukovacího dutého nože a roztěracích válců na naťírací papír o plošné jednotce 84 g/m2. Nátěr byl po usušení šatériován. Pro srovnání byl stejný natírací papír natřen natírací hmotou, ve které místo suspense saténové běloby podle vynálezu byla obsažena obvyklá pasta saténové běloby. Vlastnosti obou pájáírů byly postaveny v tabulce 3 proti sobě. Je zřejmé, že suspense saténové běloby, vyrobená způsobem podle vynálezu působí značné zvýšení hladkosti (Bekkscho-The coating composition was applied in an amount of 21 g / m 2 on a coating machine by means of a combination of an inflatable hollow knife and spreading rollers on a coating paper having a surface area of 84 g / m 2 . The paint was dried after drying. For comparison, the same coating paper was coated with a coating composition in which a conventional satin white paste was contained in place of the satin white suspension of the invention. The properties of the two solders were opposed in Table 3. Obviously, the satin white suspension produced by the process of the invention causes a significant increase in smoothness (Bekkscho
