Problems solved by technology

[0003]However, it is difficult to prepare and retain the pattern layer in the existing multi-layer elastic film structure, because the elastic material will cause the pattern layer to easily deform or even disappear, which limits the application of films with textured surfaces

Abstract

The invention discloses an elastomer protective film with patterns and a preparation method thereof. The preparation method comprises the following steps: (1) hot-pressing the patterned film and the elastomer base film to form a surface layer with concave patterns; The surface is coated with a photocurable coating composition and a photoinitiator, and irradiated with ultraviolet light at room temperature; (3) coating the back glue on the surface layer of the concave pattern, and baking and curing at 70-80°C to obtain a patterned pattern Self-healing elastomeric protective film. The surface layer of the patterned self-repairing elastic body protective film prepared by the invention has strong adhesion to the patterned layer, is not easy to fall off, has good friction resistance and good weather resistance on the surface, and has self-repairing function.

Description

technical field [0001] The invention relates to the field of film preparation, in particular to a patterned elastomer protective film and a preparation method thereof. Background technique [0002] The existing multi-layer films containing polyurethane material layers are widely used in the automotive industry. With the improvement and transformation of people's aesthetic ability, single-tone products have become increasingly unable to meet people's aesthetic needs. Multilayer film with textured effect. Especially in terms of paint protection film, for decorative effect, the surface of the paint protection film needs to show patterns. [0003] However, it is difficult to prepare and retain the pattern layer in the existing multilayer elastic film structure, because the elastic material will cause the pattern layer to easily deform or even disappear during subsequent heat treatment, thus limiting the application of the film with the pattern on the surface.
