Abstract

POSTUPAK ZA DOBIJANJE MIKROKAPSULA, NA TAJ NAČIN DOBIJENE MIKROKAPSULE I NJIHOVA PRIMENA, opisano je mikrokapsuliranje hidrofobnih ulja sa u njima rastvorenim ili dispergovanim supstancama, posebno sa bojenim reakcionim partnerima iz bojenih reakcionih sistema, pri čemu se ulje umešava u vodeni medijum koji sadrži jedinjenje koje stabiliše disparziju, u dobijenoj ulje-u-vodi-disperziji se na uobičajen način obrazuju aminoplastne kapsule koje se u datom slučaju na kraju izoluju. Vodeni medijum sadrži u vodi rastvoran modifikovan anjonski melamin-formaldehid-predkondenzat kao i jedno takvo u vodi rastvorno katjonsko jedinjenje, koji u medjusobnoj interakciji obrazuju jedno jedinjenje koje stabiliše disperziju. Modifikovani melamin-formaldehid-predkondenzat se dobija na taj način, što se melamin i jedan aldehid u alkalnom vodenom medijumu na sulfitom alkalnog metala ili sulfitom zemnoalkalnog metala, jednim sulfamatom alkalnog ili zemnoalkalnog metala, jednom aminosulfonskom kiselinom, jednom amino karbonskom kiselinom i/ili jed-nom amino dikarbonskom kiselinom konvertuju u predkondenzat, ovaj se zatim podvrgava polikondenzaciji na taj način što se zakišeljava sa sulfaminskom kiselinom, jednom amino-, jednom aminodi-, jednom hidroksi- i/ili jednom polihidroksi karbonskom kiselinom i/ili jednom amonosulfonskom kiselinom, i posle završene polikondenzacije dobijeni rastvor smole se u datom slučaju zaalkališe. Ovaj postupak isključuje opterećenje stranim solima, može se fleksibilnije podešavati i dovodi do pojedinačnih kapsula bez aglomerata.
