A process for producing composite panels comprising a natural stone slab and a reinforcement bonded to the natural stone slab, and composite slabs produced by the processes

摘要

The invention relates to a method for producing a composite panel, wherein a first adhesive (2) is applied over its entire surface to a not yet cut natural stone slab (1), into which still liquid adhesive (2) a mixture consisting of finely crushed rock and powdered crushed rock is interspersed, if necessary, then existing excess rock material (3) is removed, and on the remaining rock material (3), a second adhesive (4) is applied. The still liquid second adhesive (4) can be sprinkled with finely ground rock to achieve good adhesion when laying the composite panel. Alternatively, it is possible after curing of the second adhesive (4) applied thereto a layer of cementitious material (5), which preferably only the unevenness of the rock material (3) compensates, but also ensures good adhesion when laying by means of a tile adhesive. In both cases, the composite panel is cut to the desired surface size after production. In addition, composite plates produced by the method are proposed, which can have a small thickness and a large format due to their high strength and cost-effectively by means of a simple tile adhesive can be laid.
