Zusammenfassung: | 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' Methylendiphenyldiisocyanate (922);
diphenylmethane-2,4'-diisocyanate (924);
diphenylmethane-4,4'-diisocyanate (926); and
isocyanate prepolymer (932);
- mixing (504) the reactive components for generating a liquid polyurethane reaction mixture (129);
- applying (506) the polyurethane reaction mixture (128) to a ground (103) of the sports field before chemical reactions in the reaction mixture have generated a solid polyurethane foam, the polyurethane foam after its solidification to be used as the polyurethane flooring. |
