PURPOSE: To enhance the dispersibility of inorg. powder by incorporating a specified amt. of ≥1 kind among specified fatty acid, alkyl succinate, and alkenyl succinate, and a specified amt. of an alkylene oxide-added type nonionic surfactant into the titled dispersant composition. n CONSTITUTION: From 20 to 500pts.wt. alkylene oxide-added type nonionic surfactant is incorporated into 100pts.wt. of at least one kind among a fatty acid having 7W23C alkyl group or alkenyl group and one or two carboxyl groups, an alkyl succinate, and an alkenyl succinate to prepare the dispersant composition for inorg. granular particles. Stearic acid, oleic acid, etc., can be exemplified as the fatty acid, and a material obtained by adding 3W16mol ethylene oxide to 1mol octyl phenol, etc., are used as the nonionic surfactant. n COPYRIGHT: (C)1987,JPO&Japio |
