Abstract
PURPOSE: To prepare a cross-linked vinyl chloride foam having an intended thickness and a high effective availability of a foaming agent by a method wherein a plurality of cross-linked foamable sheets are attached to each other, heated and expanded.
CONSTITUTION: Intended quantities of plasticizer, stabilizer, cross-linking assistant and foaming agent are added to vinyl chloride resin. The vinyl chloride is gelled sufficiently without decomposing the foaming agent. They are mixed homogeneously. This mixture is molded by an extruder on the like into a sheetlike body with a thickness in the range permitting the transmission of an electron ray irradiator. Then, the electron rays β are irradiated on this sheet to obtain a sufficiently cross- linked foamed sheet. Then, in order to laminate a plurality of these sheets, hot air or infrared rays are projected on the surfaces to be laminated and heated until they are softened sufficiently and welded and laminated by a press roll to obtain a primary plate. This primary plate is heated beyond the decomposition temperature of the foaming agent and expanded to generate foams.
