The invention discloses a water-based polyurethane/organosilicon composite mirror leather and a preparation method thereof, which specifically includes the following steps: S1. Foaming a primer resin by 1.1-1.5 times, and then applying a method of direct coating, roller coating or sharp knife coating. On the base cloth, the amount of coating is 10-30 strips, and drying after coating; S2, then use release paper on the dry line, and coat the silicone rubber resin on the release paper on the first coating table, and the coating The amount is 10-20 strips, and dried at 100-120 ℃; then the fabric silicone rubber resin is coated on the second coating station, the coating amount is 20-30 strips, and the drying is at 100-120 ℃. The water-based polyurethane/organosilicon composite mirror leather prepared by the invention has good non-porous effect, fine crease and quick recovery, good hydrolysis resistance effect and high mechanical strength. The present invention combines the advantages of the two, applies organic silicon resin to the surface layer, and uses water-based polyurethane resin for the base material and the bottom layer to obtain the water-based polyurethane/organic silicon composite mirror leather. |
