METHOD FOR MANUFACTURING ULTRATHIN NATURAL STONE SLAB, ULTRATHIN NATURAL SLAB MANUFACTURED THEREBY AND FLOORING USING ULTRATHIN NATURAL SLAB

摘要

The present invention relates to a method for manufacturing an ultrathin natural stone slab, an ultrathin natural slab manufactured thereby and flooring using the ultrathin natural slab, according to which the ultrathin natural slab has high brittle strength, maintains a certain level of strength even after being processed to an ultrathin natural slab, is highly resistant to shock and thus does not break with the help of a shock-absorbing base layer and is protected from warping. To this end, the method for manufacturing an ultrathin natural slab comprises: preparing a 1st slab layer by cutting natural stone at a thickness greater than that of the slab layer to be processed as a final product; forming a 1st adhesive layer by applying an adhesive resin to one side of the 1st slab layer; forming a reinforcement layer by bonding a reinforcement member to the 1st adhesive layer; forming a 2nd adhesive layer by applying an adhesive resin to the reinforcement layer; bonding a 2nd slab layer to the 2nd adhesive layer, the 2nd slab layer being prepared by cutting natural stone at a thickness greater than that of the slab layer to be processed as a final product; and performing post-treatment by cutting the surface of the 1st and 2nd slab layers at a final processing thickness.
