Abstract
A method for manufacturing resin films includes steps of mixing PU resin and hydroxyl compound to become a first-kind first-phase mixture, and of mixing a pigment with a foaming agent to become a second-kind mixture, of injecting the first-kind mixture into a kneading device to get mixed and kneaded to become a first-kind second-phase mixture, of sending the first-kind second-phase mixture into a second kneading device to get a first-kind third-phase mixture, and the second-kind mixture and the first-kind third-phase mixture both sent into a conveyer to get a third-kind mixture, and the final step is to send the third-kind mixture into a coating device for coating the third-kind mixture on a substrate cloth to get a resin film of an original color and fresh brilliance.
Claims10
A method for manufacturing resin films comprising:
- A first step of injecting polyurethane (PU) containing at least NCO and hydroxyl compound containing OH in a first injecting mixing device for mixing the both to get a first-kind first-phase mixture:
- A second step of injecting a pigment and a foaming agent in a second injecting mixing device for mixing the both to get a second-kind mixture:
- A third step of injecting said first-kind first-phase mixture into a first kneading device for mixing and kneading to get a first-kind second-phase mixture:
- A fourth step of injecting said first kind second-phase mixture in said first kneading device into a second kneading device for further mixing and kneading to become a first-kind third-phase mixture:
- A fifth step of injecting said first-kind third-phase mixture into a conveyer, and of injecting said second-kind mixture into said conveyer for carrying out mixing said second-kind mixture with said first-kind third-phase mixture to get a third-kind mixture:
- and,
- A sixth step of sending said third-kind mixture into a coating device, which then performs coating said third-kind mixture on a substrate cloth to form a resin film.
