Abstract
The present invention relates to a method for molding rubber blocks by combining rubber chips and a urethane binder, and more specifically to a molding method for rubber blocks whereby it is possible to improve the processing time and the physical properties of the product by introducing high-temperature steam during molding. The present invention has advantageous effects in that the molding can take place in a short time without affecting the physical properties of the product even in situations involving heavy molded products, and in that there is no risk of ignition due to self-heating even if the finished products are kept stacked.
