Preparation method of poly-urethane mounting pad and poly-urethane mounting pad |
| abstract |
The present invention relates to a method for preparing a polyurethane resin composition, comprising the steps of: injecting a polyurethane resin composition containing a polyurethane resin and a DMF solvent into a coagulation tank in a direction perpendicular to the surface of the coagulation liquid; And a wet coagulation step of moving the injected polyurethane resin composition at a moving speed of V in a coagulation bath containing DMF aqueous solution or water, wherein the thickness (T [mm]) of the polyurethane resin composition, Wherein the polyurethane resin composition has a constant injection distance (D [m]) of the polyurethane resin composition and a moving speed (V [m / min]) of the polyurethane resin composition. According to this, long and large pores uniformly inclined in the support pad can be formed, and the support pad can achieve more uniform and high efficiency polishing with excellent compression ratio and high elastic modulus. |
