Abstract
The invention relates to a method of manufacturing non-slip floor coverings made of mineral materials, such as, for example, natural stone, fine stoneware, artificial stone or ceramics. This method is carried out in a two-stage process, there being produced on the surface of the floor coverings or slabs, in a first process stage by means of pulsed laser bombardment, statistically distributed microcraters invisible to the human eye. The surface of the floor coverings or slabs obtained in this way is then, according to the invention, subjected to hydromechanical aftertreatment.

Method for manufacturing non-slip floor coverings or floor slabs, the non-slip floor coverings or slabs made of mineral materials having depressions in a 2-stage process by means of pulsed laser bombardment, there being produced, statistically distributed, on the surface of the floor covering, through the targeted action of laser pulses, microcraters acting like suction cups which are invisible to the human eye, characterized in that, in a second process stage, the surface of the laser-structured floor coverings or slabs so produced is subjected to purposeful hydromechanical post-treatment, it being represented that the hydromechanical post-treatment comes about in such a way that the surface of the laser-structured floor coverings or slabs is sprayed with liquid at least twice providing at least two spraying operations, at least one spraying operation serving to etch parts of the surface of the microcraters and thus enlarge same, and wherein of the at least two spraying operations, the last spraying operation serves to at least one of clean and neutralise the surface of the floor coverings or slabs from previous spray liquids.
In a method for the manufacturing of non-slip floor coverings or floor slabs, the non-slip floor coverings or slabs made of mineral materials having depressions in a two-stage process including the steps of bombarding the floor coverings or floor slabs with a pulsed laser, forming and statistically distributing microcraters on the surface of the floor coverings or floor slabs through the targeted action of laser pulses, the microcraters acting like suction cups, invisible to the human eye, to form laser-structured floor coverings or slabs, the improvement comprising the steps of:
- in a second process stage, subjecting the surface of the laser-structured floor coverings or floor slabs to purposeful hydro mechanical post-treatment, spraying the laser-structured floor covering with liquid, providing at least two spraying operations, spraying the laser-structured floor coverings or slabs for etching parts of the surface of the microcraters and thus enlarging the microcraters, and providing a last spraying operation for at least one of cleaning and neutralizing the surface of the floor coverings or slabs from previous spray liquids.
