Abstract

PURPOSE: To obtain an aqueous emulsion of a phenolic resin of fine particle size, having improved storage stability, water and heat resistance, by emulsifying a phenolic resin precondensate with a colloid protecting agent and hexamethylenetetramine.
CONSTITUTION: A colloid protecting agent and hexamethylenetetramine in the minimum amounts required to make a phenolic resin precondensate a water-in-oil type emulsion are added to the precondensate to form an emulsion. The precondensate is obtained by reacting one mole of a plenol with 1.0W3.0 moles of formaldehyde in the presence of a basic catalyst. Hexamethylenetetramine (H) may be used in the form of powder, an aqueous solution, or a mixture of formaline and an aqueous ammonia wherein (H) is formed. Acacia, casein polyvinyl alcohol, or hydroxyethyl cellulose, may be used as the protecting agent.
