Problems solved by technology

However, this method of protecting the surface of the substrate workpiece is cumbersome on the one hand. The surface treatment of the substrate workpiece is divided into two steps: surface coating and surface painting, and after surface coating, drying treatment is generally required before painting. Then paint, etc.; on the other hand, directly spraying the surface of the substrate workpiece that has been coated with a pattern will require stricter spraying process control, because the wrinkle rate, sagging and coating thickness of the sprayed surface should be considered. Uniformity, etc., while the surface complexity and diversity of three-dimensional substrate workpieces can easily lead to poor spraying effects

Embodiment 1

[0036] Such as figure 1 As shown, the water transfer coating film of the present embodiment includes a PVA film 1, a layer of UV photocurable coating 2 formed on the surface of the PVA film 1 and a pattern layer 3 printed on the top of the UV photocurable coating 2 .

[0037] The manufacturing method of the water transfer printing coating film is:

[0038] (1) PVA film is purchased from the market;

[0039] (2) Coating a UV light-curing coating on the PVA film and forming it by UV light irradiation;

[0040] (3) Then print another layer of pattern layer 3 on top of the UV photocuring coating.

[0041] The above-mentioned PVA film can also be replaced by water-based PVC film or water-based PET, and the UV photocurable coating can also be replaced by PU coating or PE coating.

Embodiment 2

[0043] Such as figure 2 As shown, the water transfer coating film of the present embodiment comprises a PVA film 1, a layer of PU coating 2' containing nano ceramics formed on the surface of the PVA film 1, and a PU coating 2 printed on the surface of the PVA film 1 containing nano ceramics. ' Pattern layer 3 above.

[0044] The manufacturing method of the water transfer printing coating film is:

[0045] (1) A layer of PVA resin is coated on the release paper, and it becomes a transparent PVA film after the PVA resin is dried;

[0046] (2) Add a small amount of 20-80nm nano-ceramics into the PU coating and mix evenly to form a PU coating containing nano-ceramics;

[0047](3) Coating the PU coating containing nano-ceramics obtained in the above steps on the PVA film to obtain a PU coating 2' containing nano-ceramics;

[0048] (4) Then, a pattern layer 3 is printed on the PU coating 2' containing nano-ceramics.

[0049] The above-mentioned PVA films can also be replaced by...

Embodiment 3

[0051] Such as image 3 As shown, the water transfer coating film of the present embodiment comprises a PVA film 1, a nano-silver oxide coating 21 and a PE coating 22 arranged in sequence from bottom to top formed on the surface of the PVA film 1, and a printed on The pattern layer 3 above the PE coating 22.

[0052] The manufacturing method of the water transfer printing coating film is:

[0053] (1) PVA film is purchased from the market;

[0054] (2) Coating a nano-silver oxide coating 21 on the PVA film;

[0055] (3) Coating a layer of PE coating 22 on the nano-silver oxide coating 21;

[0056] (4) Then, another pattern layer 3 is printed on the PE coating layer 22 .

[0057] The above-mentioned PVA film can also be replaced by water-based PVC film or water-based PET, PE coating can also be replaced by UV coating or PU coating, nano-silver oxide coating can also be replaced by nano-ceramic coating, nano-carbon tube coating or nano-aluminum coating replace.

Abstract

The invention relates to a water transfer printing coating film, its making method, and a surface coating method using the water transfer printing coating film. The water transfer printing coating film is characterized in that the water transfer printing coating film comprises a water-soluble film, at least one functional coat formed on the surface of the water-soluble film, and a pattern layer printed on the functional coat. 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.

Description

technical field [0001] The invention relates to a water transfer printing coating film, a manufacturing method thereof, and a surface coating method using the 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 ...
