Abstract

The present invention relates to novel compounds in the form of alkyl amine acid addition salts, which compounds have the ability to regulate the viscosity of coating mixes when mixing together mixes of mutually different basic compositions. The invention also relates to the use of such alkyl amine acid addition salts for controlling the viscosity of a combined mixture of such coating mixes.

Produkten framställes genom att blanda en lösning av en alkylamin med en lös- ning av en lämplig syra för reaktion till bildning av avsett syraadditionssalt.The product is prepared by mixing a solution of an alkylamine with a solution of a suitable acid for reaction to form the intended acid addition salt.

Härvid är det oväsentligt om den ena lösningen sättes till den andra, eller vice versa.In this case, it is immaterial whether one solution is added to the other, or vice versa.

Respektive lösning kan utgöras av koncentrat eller resp. förening löst i ett lös- níngsmedel.The respective solution can consist of concentrate or resp. compound dissolved in a solvent.

Beroende på graden av önskad substitution tages 1-4 moler amin per mol syra.Depending on the degree of substitution desired, 1-4 moles of amine are taken per mole of acid.

Vid användning av alkylaminsyraadditionssaltet har det visat sig möjligt att få en godtagbar effekt även då endast en del av alkylaminen föreligger i form av sådant syraadditionssalt.When using the alkylamic acid addition salt, it has been found possible to obtain an acceptable effect even when only a part of the alkylamine is present in the form of such an acid addition salt.

Det är vidare möjligt att tillsätta saltkomponenterna, dvs alkylamin och syra, var för sig direkt till bestrykningssmeten för uppnående av ett bra resultat. 10 451 470 Med kaolinbaserad smet avses häri en smet som innehåller mer än 50% kaolin av pigmentdelen. Det är sålunda känt kaolínsmetar med 60% kaolín och 4096 gips.It is further possible to add the salt components, i.e. alkylamine and acid, separately directly to the coating batter to achieve a good result. By kaolin-based batter is meant herein a batter which contains more than 50% kaolin of the pigment moiety. It is thus known kaolin anglers with 60% kaolin and 4096 gypsum.

Med kritabaserad smet avses en smet som innehåller mer än 5096 krita, och_ med gipsbaserad smet en smet som innehåller mer än 5Ö96 gips. Pígmentdelen behöver sålunda ej vara 100%-igt baserad på ett pigment.Chalk-based batter refers to a batter that contains more than 5096 chalk, and gypsum-based batter a batter that contains more than 5Ö96 gypsum. Thus, the pigment portion need not be 100% based on a pigment.
