Abstract
The invention discloses a pattern roller for release paper and a preparation method thereof. The preparation method comprises the following steps of polishing a seamless steel roller to obtain a bright surface of the seamless steel roller, coating a photoresist layer on the bright surface of the seamless steel roller, drying the photoresist layer, carrying out exposure of a preset area, carrying out development, chemical curing of a membrane and heat hardening of the membrane, corroding a non-preset area by a chemical corrosive liquid to obtain a coarse concave surface, removing the photoresist layer, and plating a decorative chromium layer so that the pattern roller is obtained. After patterns are formed on the seamless steel roller by the photoresist layer, a seamless steel roller surface which is not coated by the photoresist layer is corroded by the chemical corrosive liquid so that the seamless steel roller surface has a certain roughness. Therefore, the preparation method solves the problem that the traditional mechanical treatment method for forming patterns can damage the patterns easily. The pattern roller obtained by the preparation method has bright surfaces of convex parts and coarse microstructures of concave parts. An artificial leather product produced by the pattern roller has corresponding visual effects.
