Description

Physical wire drawing texture PET film

Technical Field

The utility model relates to a PET membrane, especially a physics wire drawing texture PET membrane.

Background

With the social development, people have increasingly strong requirements on the surface decoration of products; many products have surface imitation metal wire drawing texture decorations. However, the process of coating the surface with the wire drawing texture is adopted, and the process is particularly applied to household appliance control panels, high-grade membrane switches and refrigerator shell wire drawing texture composite boards. However, most of the PET thin films processed into the wire-drawing texture at present are processed by a UV coating transfer printing mode, although the wire-drawing texture effect can be achieved; after all, the surface of the product is formed by a coating process, the anti-aging performance of the UV wire-drawing texture on the surface is not strong, and the service life is only 3-5 years; and the UV wiredrawing layer is easy to fall off during bending and embossing treatment.

The wire drawing texture layer is a polyurethane layer, the thickness of the wire drawing texture layer is 1-3 mu m, the wire drawing texture layer is prepared from an upper coating layer in a physical grinding mode, the wire drawing textures are different due to different purposes (such as printing, electroplating and the like), when the wire drawing texture layer is only used for printing, the thickness of the wire drawing physical layer is small, and when the wire drawing texture layer is used for electroplating, the thickness of the wire drawing texture layer is large, the depth of the texture is also large, so that metal particles are easy to attach to the wire drawing texture layer.

The upper coating is a polyurethane layer with the thickness of 2-7 mu m.

The lower coating is a polyurethane layer with the thickness of 1-4 mu m, and the lower coating is used as an intermediate medium to mainly better combine the PET film with later-stage screen printing solvent-based ink, so that the adhesive force between the PET substrate and the subsequent printing ink is improved

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

as shown in fig. 1, the physical wire-drawing texture PET film comprises an upper coating layer 2, a PET substrate 3, a lower coating layer 4 and an anti-static protective film 5, wherein the wire-drawing texture layer 1 is integrally formed above the upper coating layer 2, the upper coating layer 2 and the lower coating layer 4 are respectively attached to the upper surface and the lower surface of the PET substrate 3, and the surface of the lower coating layer 4 is attached with the static protective film 5.

The wire-drawing texture layer 1 is a polyurethane layer and has the thickness of 1-3 mu m, the wire-drawing texture layer 1 is prepared from the upper coating layer 2 in a physical grinding mode, the wire-drawing textures are different due to different purposes (such as printing, electroplating and the like), when the wire-drawing texture layer is only used for printing, the thickness of the wire-drawing physical layer is smaller, and when the wire-drawing texture layer 1 is used for electroplating, the thickness of the wire-drawing texture layer 1 is larger, the depth of the texture is larger, so that metal particles are easy to attach to the wire-drawing texture layer 1.

The upper coating 2 is a polyurethane layer with the thickness of 2-7 m, and the lower coating 4 is a polyurethane layer with the thickness of 1-4 μm. The lower coating 4 is used as an intermediate medium and mainly plays a role in better combining the PET film with later-stage screen printing solvent type ink, the adhesive force between the PET substrate and the subsequent printing ink is improved, and by adopting the upper coating 2 and the lower coating 4, the PET film can meet the large-angle bending requirement of an injection molding part, and the coating is not easy to fall off and crack in the stretching process and has strong tensile resistance.
