Abstract

Przedmiotem zgłoszenia jest preparat do kondycjonowania granulowanego mocznika charakteryzujący się tym, że jest mieszaniną składników i zawiera produkty wielostopniowej reakcji polikondensacji formaldehydu z mocznikiem prowadzonej dwuetapowo początkowo w środowisku alkalicznym, a następnie w środowisku kwaśnym o stosunku molowym formaldehydu do mocznika zawartym w granicach 1:1 do 6:1 w ilości do 95% (składnik 1), produkty reakcji formaldehydu z 1,4-dietylenodiaminą o stosunku molowym formaldehydu do 1,4-dietylenodiaminy zawartym w granicach 1:1 do 2:1 w ilości do wagowych (składnik 2), wodny roztwór mocznika ilości do 25% wagowych (składnik 3) oraz środek powierzchniowo-czynny o charakterze kationowym w ilości do 5% wagowych (składnik 4).The subject of the application is a preparation for conditioning granulated urea, characterized in that it is a mixture of components and contains products of a multi-stage polycondensation reaction of formaldehyde with urea carried out in two stages, initially in an alkaline medium and then in an acidic medium with a molar ratio of formaldehyde to urea within the range of 1:1 to 6:1 in an amount of up to 95% (component 1), reaction products of formaldehyde with 1,4-diethylenediamine with a molar ratio of formaldehyde to 1,4-diethylenediamine within the range of 1:1 to 2:1 in an amount by weight (component 2), an aqueous urea solution in an amount of up to 25% by weight (component 3) and a cationic surfactant in an amount of up to 5% by weight (component 4).
