| Abstract: | Synthesis of the urea formaldehyde resin using poly merization of urea and formaldehyde in acid medium is described . During the cou rse of preparation , formic acid was pH value conditioning agent of condensation polymerization .The preparation of the foam material of urea formaldehyde resi n proves ammonium bicarbonate foaming is the better for economical and convenien t , and the optimum parameter is as following : urea formaldehyde resin 100 g , corn starch 15 g , surface active agent 8~16 g , ammonium bicarbonate 6 g , 75% phosphoric acid 25 mL . |
