MANUFACTURE OF OUTER FACE REINFORCED PLASTIC FOAMED MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an outer face reinforced plastic foamed molded material in which the superior finished state and the dimension accuracy are securely provided at all times without the necessity of special skill. SOLUTION: A plastic foamed molded product F is so disposed in a frame M as to form a space S having a given clearance between the inner surface of the flame M and the outer surface of the foamed molded product F. Then a two-liquid reactive non-solvent urethane resin composition (u) is injected into the space S, filled and cured therein and then released from the flame M, An outer face reinforced plastic foamed molded material with a coated layer U formed integrally is provided on the surface of the foamed molded product F by the arrangement. Also a protruded section G for forming the space can be formed at least on one of the outer faces of the foamed molded product F or the inner face of the flame M. A guide channel can also be formed on the surface of the foamed molded product F.
