Problems solved by technology

[0004] However, there are some problems in the surface coating of products using the water transfer coating film of the prior art, for example: (1) Due to the nature of the ink itself, the pattern coated on the product surface may be easily worn or peeled off , it is necessary to strengthen the protection of the covered pattern;
[0005] (2) The surface of the product covered by the surface may need to achieve certain properties, such as wear resistance, flame resistance, etc., which requires spraying the substrate workpiece itself after the above-mentioned water transfer printing surface coating process is completed One layer of protective paint, such as the Chinese invention patent application whose publication number is CN101695891A adopts this method exactly. After the pattern is transferred to the product surface, it is dried and then sprayed with topcoat to form a transparent protective coating; On the one hand, the method of protecting the surface of the material workpiece is relatively cumbersome. The surface treatment of the substrate workpiece is divided into two steps: surface coating and surface painting. On the other hand, directly spraying the surface of the substrate workpiece that has been coated with a pattern will require stricter control of the spraying process, because the wrinkle rate, sag and coating thickness uniformity of the sprayed surface must be considered, and The complex and diverse surface of the three-dimensional substrate workpiece can easily lead to poor spraying effect;
[0006] (3) Due to the gradual dissolution and diffusion of the water-soluble film layer in water, the ink of the pattern layer above the water-soluble film layer is easy to spread, deform, and shift, resulting in color difference. The deformation of some patterns can reach 165%, and the image accuracy The average is 300-400dpi, and the maximum is no more than 600dpi, which seriously affects the coating quality of the product surface

Abstract

The invention relates to a novel water transfer printing coating film. The novel water transfer printing coating film comprises a water-soluble film and a coating layer formed on the water-soluble film; the coating film comprises a plurality of pattern areas and at least one coating area, the pattern areas are arranged in a spaced manner, the at least one coating area is connected with the outside of the plurality of pattern zones and encircles around the plurality of pattern zones, each of the pattern zones is composed of at least one functional coat and a printing ink coat which are distributed from bottom to top. The water transfer printing coating film realizes the one-time surface coating of the pattern and the protection coat of a substrate workpiece, and has the advantages of simple operation, cost saving, production efficiency improvement, and guarantee of the coating surface of the surface coat; and the coating is completed, the deformation quantity and the displacement quantity of a surface coating pattern are substantially reduced, and the integrity and the image precision of the pattern are guaranteed.

Description

technical field [0001] The invention relates to a novel water transfer printing coating film. Background technique [0002] Due to the problem that complex and changeable objects with three-dimensional structures and curved surfaces are difficult to realize by traditional printing methods, three-dimensional surface coating technology has developed rapidly in recent years, for example: a large number of industrial products such as mobile phone casings, anti-theft doors, various All kinds of furniture, home appliances, automotive products and cosmetics industry products have chosen to print patterns through three-dimensional surface coating technology, and this method is widely used in more and more industries. [0003] The existing water transfer printing coating film is to coat a layer of water-soluble resin on the release paper, and after the water-soluble resin dries, it becomes a transparent film layer, and then ink printing is performed on the water-soluble film layer to...
