Title:
MANUFACTURE OF ROSIN-BASED EMULSION SIZING AGENT
Document Type and Number:
Japanese Patent JPS60133052
Kind Code:
A
Abstract:
PURPOSE: To easily obtain titled agent with assurance through an inversion process, high in stability and great in its sizing effect, by using, as dispersant, a combination of specific surfactant with water-soluble acid.
CONSTITUTION: (A) A molten rosin material is admixed with (B) an acidic dispersant aq. solution (pref. a pH 2.5W3.5) containing (i) 2W10wt% based on the component (A) of a surfactant of formula (R is 8W24C hydrophobic hydrocarbon; M is monovalent cation; n is 5W25) and (ii) 5W10wt% based on said surfactant, of a water-soluble acid (e.g. hydrochloric acid, nitric acid) to form a homogeneous dispersion followed by adding, while stirring, warm water to effect phase inversion, thus obtaining the objective agent.
