The invention discloses a water-based polyurethane/organic silicon composite mirror leather and a preparation method thereof, specifically comprising the following steps: S1, foaming the primer resin by 1.1-1.5 times, and then applying the method of direct coating, roller coating or sharp knife coating On the base cloth, the amount of coating is 10-30 strips, and it is dried after coating; S2, then use a release paper on the dry method line, and coat the silicone rubber resin of the fabric on the release paper on the first coating table, and the coating The amount is 10‑20 strips, dried at 100‑120 °C; then the fabric silicone rubber resin is coated on the second coating table, the coating amount is 20‑30 strips, and dried at 100‑120 °C. The water-based polyurethane/organic silicon composite mirror leather prepared by the invention has good non-porous effect, fine and fast recovery of creases, good hydrolysis resistance effect and high mechanical strength. The 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 base layer to obtain the water-based polyurethane/organic silicon composite mirror leather. |
