Description
Fremgangsmåte til fremstilling av et titanoxyd-sinkoxydpigment. Process for producing a titanium oxide-zinc oxide pigment.
Det er kjent at titandioxyd som pigment har den fordel fremfor sinkoxyd at It is known that titanium dioxide as a pigment has the advantage over zinc oxide that
det dekker bedre, men den ulempe at det it covers better, but the disadvantage that it

Grunnen til dette er at titandioxyd har en betydelig fotokjemisk aktivitet. influence, infects and bleaches other color pigments that are mixed with the titanium oxide. The reason for this is that titanium dioxide has a significant photochemical activity.
For å minske nevnte ulemper har man To reduce the aforementioned disadvantages, one has

Det er også forsøkt å eliminere nevnte Attempts have also been made to eliminate the aforementioned
ulemper ved anvendelse av sinktitanater disadvantages of using zinc titanates
som pigmenter. Herved oppvarmet man as pigments. This warmed up
blandinger av titanoxyd og sinkoxyd i forholdet 0,9—2,1 mol ZnO pr. mol TiOs så mixtures of titanium oxide and zinc oxide in the ratio 0.9-2.1 mol ZnO per mol TiOs so
lenge til temperaturer mellom 500 og 1000 long to temperatures between 500 and 1000
°C til minst 95 pst. av sinkoxydet var gått °C until at least 95 per cent of the zinc oxide had gone
over i sinktitankrystaller av spinell- eller into zinc titanium crystals of spinel or
korundtypen (tysk patentskrift 648 518). the corundum type (German patent document 648 518).
Det er videre foreslått å fremstille pigmenter i form av sinktitanat med hexago-nal symmetri og ilmenittstruktur ved å It is further proposed to produce pigments in the form of zinc titanate with hexagonal symmetry and ilmenite structure by
oppvarme en blanding av gamma-titandioxyd med sinkoxyd i så lang tid at bare heat a mixture of gamma-titanium dioxide with zinc oxide for such a time that just
sinktitanat lot seg påvise (US patentskrift 2 379 019). Imidlertid har også slike sink-titanatpigmenter de ovenfor nevnte ulemper. zinc titanate could be detected (US patent 2,379,019). However, such zinc-titanate pigments also have the above-mentioned disadvantages.
Ved hjelp av foreliggende oppfinnelse By means of the present invention
oppnås fremstilling av pigmenter som for production of pigments such as for
en vesentlig del består av et titanoxyd og a significant part consists of a titanium oxide and
som ikke har de nevnte ulemper. which do not have the aforementioned disadvantages.
Oppfinnelsen er basert på flere nye The invention is based on several new ones
erkjennelser som er gjort av oppfinneren, nemlig den erkjennelse at den reaksjon ved hvilken der dannes en fast oppløsning av titandioxyd og sinkoxyd (hittil betegnet som sinktitanat), er en diffusjonsreaksjon, og videre på den erkjennelse at graden av denne faste oppløsnings fotokjemiske reaksjon i vesentlig grad er avhengig av den dif fusjonsenergi som ble anvendt ved den faste oppløsnings fremstilling. recognitions made by the inventor, namely the recognition that the reaction by which a solid solution of titanium dioxide and zinc oxide (heretofore referred to as zinc titanate) is formed is a diffusion reaction, and further to the recognition that the degree of this solid solution's photochemical reaction essentially degree is dependent on the diffusion energy that was used in the preparation of the solid solution.
En liten dif fusjonsenergi får man bare når man bruker utgangsmaterialer hvis A small diffusion energy is only obtained when starting materials are used if
krystaller viser forstyrrelse av krystallgit-teret, f. eks. som følge av forurensninger eller innføring av fremmede stoffer. Titandioxyd har for det meste slike krystallfeil i tilstrekkelig grad, f. eks. ved innføring crystals show disturbance of the crystal lattice, e.g. as a result of contamination or the introduction of foreign substances. Titanium dioxide mostly has such crystal defects to a sufficient extent, e.g. upon introduction
av fosfationer eller sulfationer eller ved nærvær av A120.,, Si02 eller Zno. of phosphate ions or sulfate ions or in the presence of A120.,, SiO2 or Zno.
En ytterligere viktig erkjennelse i for-bindelse med fremstilling av faste oppløs-ninger av titanoxyd som krever så liten dif fusjonsenergi at der ved anvendelse av slike faste oppløsninger som pigmenter bare kan opptre en ubetydelig fotokjemisk reaksjon, er arten av det anvendte sinkoxyd. Ifølge oppfinnelsen egner der seg for fremstilling av zinktitanater for anvendelse som farvepigment bare hexagonalt, nåleformet, sulfatert sinkoxyd med et svovelinnhold på minst 0,1 pst. beregnet som S03, men med minst 0,04 pst. S. A further important realization in connection with the production of solid solutions of titanium oxide, which require so little diffusion energy that when using such solid solutions as pigments only an insignificant photochemical reaction can occur, is the nature of the zinc oxide used. According to the invention, only hexagonal, needle-shaped, sulphated zinc oxide with a sulfur content of at least 0.1 per cent calculated as SO3, but with at least 0.04 per cent S, is suitable for the production of zinc titanates for use as a color pigment.
Sinkoxyd av denne art fremstilles ved langsom oxydasjon av sinkdamp i nærvær av et overskudd av ikke-oxyderende gasser, hvorved sinkoxydet får anledning til å kry-stallisere langsomt under dannelse av lange nåler. En sådan fremgangsmåte er beskrevet i U.S. patentskrift nr. 2 200 873 og i engelsk patentskrift nr. 435 005. Zinc oxide of this kind is produced by slow oxidation of zinc vapor in the presence of an excess of non-oxidizing gases, whereby the zinc oxide is given the opportunity to crystallize slowly while forming long needles. Such a method is described in U.S. Pat. patent document no. 2 200 873 and in English patent document no. 435 005.
Ifølge oppfinnelsen inneholder blandingen av titandioxyd og sinkoxyd fortrinsvis 0,5—4 mol titandioxyd pr. mol sinkoxyd. Kalsineringstemperaturen ligger mellom 500 og 1000°C, fortrinsvis under 900°C. Oppvarmningen fortsettes inntil der ikke kan påvises mere enn 5 pst. fritt sinkoxyd i den kalsinerte blanding. According to the invention, the mixture of titanium dioxide and zinc oxide preferably contains 0.5-4 mol of titanium dioxide per moles of zinc oxide. The calcination temperature is between 500 and 1000°C, preferably below 900°C. The heating is continued until no more than 5 per cent of free zinc oxide can be detected in the calcined mixture.
Ved etterbehandling som vanlig for pigmenter, i alminnelighet for oppdeling av agglomerater som har dannet seg under kalsineringen, kan bestemte egenskaper hos pigmenter fremstillet ifølge oppfinnelsen, forbedres ytterligere. By post-treatment as usual for pigments, in general for breaking up agglomerates which have formed during the calcination, certain properties of pigments produced according to the invention can be further improved.
I det følgende beskrives som eksempler to utførelsesformer for oppfinnelsen, In the following, two embodiments of the invention are described as examples,
i in
Eksempel 1. Example 1.

Blandingen tørres og males, hvorpå den oppvarmes' y2 time til 850°C. 170 g of titanium dioxide with a rutile structure and a TiO2 content. of 94 per cent and 330 g of sulphated, needle-shaped zinc oxide with 0.2 per cent SO;j is stirred with water to a dough which is mixed well. The mixture is dried and ground, after which it is heated for 2 hours to 850°C.
Overtrekkshinner fremstillet under anvendelse av det herved erholdte pigment har meget god1 dekkevne, stor hvithet og smitter ikke av. Cover films produced using the pigment obtained in this way have very good opacity, great whiteness and do not rub off.
i in
Eksempel 2. Example 2.
I 640 vektsdeler av en vandig titan-oxydhydratsuspensjon inneholdende 30 pst. Ti02 (beregnet ;på tørrstoff), oppslemmes 205 vektsdeler hexagonalt, nåleformet sinkoxyd. Suspensjonen avvannes delvis, hvorpå den føres inn i en roterende rørovn som er innstillet slik at endeproduktet ikke inneholder mere enn 4 pst. fritt sinkoxyd, dvs. sinkoxyd som ikke har dannet fast opp-løsning med titandioxyd. Ovnens tempera-tur i glødesonen holdes på 750°C. In 640 parts by weight of an aqueous titanium oxide hydrate suspension containing 30 percent TiO 2 (calculated on dry matter), 205 parts by weight of hexagonal, needle-shaped zinc oxide are suspended. The suspension is partially dewatered, after which it is fed into a rotary tube furnace which is adjusted so that the end product does not contain more than 4 per cent of free zinc oxide, i.e. zinc oxide which has not formed a solid solution with titanium dioxide. The oven's temperature in the annealing zone is kept at 750°C.
Overtrekkshinner fremstillet med det herved erholdte pigment dekker meget godt, har stor hvithet og smitter ikke av. Cover films made with the pigment obtained in this way cover very well, have great whiteness and do not rub off.
