MANUFACTURE OF ORGANIC FOAM GLASS MOLDED PRODUCT

PURPOSE:To obtain almost a well-balanced organic foam glass molded product, by a method wherein an organic glass monomer to which beads of organic glass are loaded or a prepolymer as an air entraining agent or a mixture of those is polymerized within a mold under almost normal pressure. CONSTITUTION:A mixture ratio (weight ratio) of beads to casting resin comprised, for example, of a monomer of methacrylate or prepolymer or a mixture of those is 70:30 to 20:80, preferably 60:40 to 25:75 and if circumstances allow a matter having a perfect spherical form is preferable. When organic glass beads and deaerated casting resin with which an additive agent such as a catalyst is compounded beforehand are put into a casting mold while mixing them with each other and they are polymerized while accelerating melting and swelling of the beads by heating them from the outside, entrained air becomes a core of an air bubble by following the molting and swelling of the beads and grows up gradually to the large air bubble. A well-balanced organic foam glass sheet which can be used for edge-lighting, a shade and a face mold lighting material can be obtained in this manner.
