A METHOD FOR PREPARING THIXOTROPIC AGENT

摘要

PURPOSE: Provided is a method for preparing thixotropic agent which shows excellent heat-resistant stability, low viscosity change in storing, flow prevention effect and brilliance effect. CONSTITUTION: The method for preparing thixotropic agent comprises the steps of: (i) mixing 1 equivalent of one or two species of organic acid having 2-22 carbon numbers and 1-2 carboxyl groups with 0.5-1.1 equivalent of metal, metal oxide or metal hydroxide to prepare reactant A; (ii) mixing 1 equivalent of one or two species of organic acid with 2-22 carbon numbers and 1-2 carboxyl groups having 0.9-1.1 equivalent of one or two species of amines with 1-2 amine groups to prepare reactant B; (iii) mixing reactant A and reactant B at 5-50:95-50 weight ratio to prepare composition C; (iv) crushing the composition to be less than 50 micrometer; and (v) keeping weight ratio between the crushing materials of the composition C and organic solvent in 10-30:90-70 and swollen ripening.
