Abstract

PURPOSE: To prepare the title resin foam having low foamaldehyde odor, and suitable as a residential heat insulating material, by adding thiourea, etc. to a curing liquid as a formaldehyde acceptor.
CONSTITUTION: A curing liquid composed of (a) a curing agent (e.g. phosphoric acid), (b) a frothing agent (e.g. alkylbenzenesulfonic acid salt), (c) a wetting agent (e.g. polyethylene glycol), (d) a water quality conditioner (e.g. Ca salt, etc.) and (e) a formaldehyde acceptor comprising thiourea (and urea), is foamed and sprayed with an aqueous solution of urea-formaldehyde precondensate to obtain the objective foam. The amount of the thiourea, etc. is pref. 1W20wt% based on the solid content of the precondensate solution.
