Synthesis of Water-borne Nitro Cellulose Lacquer Using as Clear Coat in Internal Automotive Leather Parts

Many parts of internal automotive parts are madeof artificial leather, which are coated by nitrocellulose lacquer. In this research, a carboxylicfunctional group is linked to hydroxyl group ofnitro cellulose by the help of an isocyanateintermediate. After neutralization of resultingproduct, nitro cellulose became soluble in water.IPDI and TDI were used as isocyanate groupresources. The isocynate group linked to DMPAfrom one side and to nitro cellulose from anotherside via urethane bonds. After neutralization ofcarboxylic groups, modified nitro cellulose chainbecame soluble in water. Physical-mechanicalproperties of resulting film was compared toprimary nitro cellulose.
