RUBBER CHIP TILE, PREPARATION AND EXECUTION THEREOF

摘要

PURPOSE:To easily and inexpensively prepare a rubber chip tile according to a mass production system by providing a heat-meltable adhesive layer to the single surface of a rubber chip molded plate and applying a heat-meltable film to the surface of said adhesive layer. CONSTITUTION:A heat meltable adhesive layer 2 is provided to the single sur face of a rubber chip molded plate 1 and a heat-meltable film 3 is bonded to the surface of said adhesive layer 2. Pref., by interposing a primer 4 between the rubber chip molded plate 1 and the heat-meltable adhesive layer 2, the heat-meltable adhesive layer 2 is strongly bonded to the rubber chip molded plate 1 and a stable and strong rubber chip tile P is obtained. The rubber chip molded plate 1 is formed by pressing a mixture prepared by mixing a proper amount of a curable resin (b) with the mass (group) of rubber chips (a) as a binder to cure and mold the same in a predetermined compressed state and, as the rubber chips mass, one composed of particles having a particle size of about 1-3mm prepared by finely pulverizing an old tire is pref. used. As the binder, a moistur-curable polyurethane resin, a liquid polybutadiene resin and an epoxy resin are used.
