Abstract: The invention relates to a method of producing a polyurethane floor panel, the method comprising mixing rubber powder, a polyol, an isocyanate component and a thermo-selective catalyst for creating a liquid two-component polyurethane reaction mixture, the thermo-selective catalyst being adapted to trigger the reaction of the polyols and the isocyanate into polyurethane selectively in case the temperature of the reaction mixture exceeds an activation temperature of the thermo-selective catalyst stirring the reaction mixture for at least 15 minutes filling the stirred liquid reaction mixture into a mold applying pressure under a temperature that exceeds the activation temperature on the mold and removing the hardened polyurethane floor panel from the mold.

Abstract: A method for producing polyurethane flooring includes providing polyurethane reactive components including a isocyanate component and a polyol component, determining environmental data, determining process parameters for mixing the polyurethane reactive components, wherein the process parameters depend on the environmental data, mixing the foam for the polyurethane flooring by mixing the isocyanate component and the polyol component using a froth foam process with the process parameters, applying a first lane of the liquid foam to a ground, applying a second lane of the liquid foam to the ground, wherein a side edge of the second lane gets in contact with a side edge of the first lane, wherein the process parameter are determined so that the foam of the first lane is not cured before applying the foam of the second lane. Furthermore, the invention relates to an apparatus and a system for producing a polyurethane flooring.

Abstract: The invention relates to a method for producing a polyurethane flooring (129) for a sports field (136), the method comprising: providing (502) reactive components for producing polyurethane, the reactive components comprising an A component (902) being a polyol mixture and a B component (904) being an isocyanate mixture and water (914), the B component comprising: 2,2?
