Title:
METHOD FOR STABILIZING DISPERSOID
Document Type and Number:
Japanese Patent JPH01151935
Kind Code:
A
Abstract:
PURPOSE:To disperse a water insoluble substance steadily in water without an increase in viscosity of a dispersoid by adding a wax containing an emulsifying surfactant in a production of an aqueous dispersoid of a pigment, resin powder, etc. CONSTITUTION:A wax such as an animal wax, vegetable wax, petroleum wax, etc., containing a surface active agent such as polyoxyethylenealkyl phenyl ether are added to an aqueous dispersoid of a pigment, resin powder, etc., to stabilize an aqueous dispersoid of a paint, lubricant, etc. An addition amount of the wax containing an emulsifying surfactant is specified ordinarily in a range of 0.01-10% of the aqueous dispersoid, and an addition ratio of the emulsifier to the wax is specified in a range of 0.5-50%. By using this method, it is possible to disperse a water insoluble substance such as a pigment, resin powder, etc., in an aqueous dispersion medium steadily without an increase in viscosity of the dispersoid.
