Abstract

PURPOSE: Title foam having excellent mechanical strength, less formaldehyde odor and less shrinkage with the passing of time, prepared by foaming a mixture of an aqueous solution of a urea/formaldehyde precondensate and an aqueous solution containing a curing agent and a foaming agent in the presence of a synthetic resin emulsion.
CONSTITUTION: To an aqueous solution of a urea/formaldehyde precondensate prepared by reacting urea with formalin there is added 5W50wt%, based on the solids of said aqueous solution, of a synthetic resin emulsion such as a synthetic rubber latex or an acrylic acid copolymer emulsion. The resulting mixture is mixed with an aqueous solution of both a curing agent, such as phosphoric acid or sulfuric acid, and a foaming agent, such as an alkylarylsulfonate or a higher alcohol sulfate ester, and the final mixture is foamed and cured.
