Abstract
Molded objects are formed from rubber and glass products, e.g. discarded glass and rubber, by grinding the rubber and glass into small particles and then melting them in separate kilns. The melted glass and rubber are then mixed together in various proportions, i.e. 20-80% by volume of the glass being added to the rubber. An epoxy resin in an amount of 0.5-1.5% is added as a binder while the melt is being mixed to a uniform consistency. Before the melt can solidify, it is poured into a mold. Small quantities of water and/or sand may also be added to the melt if desired.
