반응 단계
A 30%-urea aqueous solution (11) at 15.2 kg/h and formalin (37%-formaldehyde aqueous solution adjusted to pH 8.0 by addition of 20%-triethanolamine aqueous solution) (12) at 11.1 kg/h were supplied to a resin prepolymer reaction vessel (13), and were caused to reside therein for 70 min. at 70° C. under stirring to continuously produce a urea resin prepolymer (formaldehyde/urea=1.8 (by mol)) liquid.
