Synergistic effects of microencapsulated ammonium polyphosphate with melamine-formaldehyde resin/ethyl cellulose on flame retardancy and hydrophobicity of cellulosic paper.
In this study, ammonium polyphosphate (APP) was sequentially microencapsulated with melamine-formaldehyde resin (MFR) and ethyl cellulose (EC). The results indicated that the pristine APP exhibited a smooth surface, and its water solubility and water contact angle (WCA) were 0.23 g/100 mL and 29.28°, respectively. Afte...
