Description

A kind of manufacturing method of deplating water transfer printing film

technical field

The invention relates to a method for manufacturing a deplating water transfer film.

Background technique

Water transfer printing film is also called surface water coating, its function is to treat the three-dimensional curved surface of the surface of irregular objects - it belongs to the overall printing of the surface. Use pure natural patterns, such as mahogany, marble, emerald, leopard skin, stripes and so on. After the object is processed, the color is vivid and the image is lifelike. To achieve the effect of confusing real ones. Completely change the surface texture of the object, and the value of the processed product will increase significantly. Applications: automotive supplies: dashboards, control panels, tissue boxes, cup holders, disk racks, rear view mirror frames, operating handles, car locks, etc.; electronic products: telephones, pagers, video recorders, audio, remote controls, mice , clocks and other household items: sofas, coffee tables, cabinets, chandeliers, ashtrays, vases, decoration containers, etc.; Rackets, accessories, cosmetic pencils, cosmetic boxes, etc.; indoor building materials: doors and windows, floors, wall panels, etc. Water transfer printing technology is known as a relatively environmentally friendly technology, and it is also the latest emerging high-efficiency printing production technology.

However, traditional water transfer printing films cannot achieve 3D effects and have no anti-counterfeiting function, resulting in weak product competitiveness and low added value.

Contents of the invention

The primary purpose of the present invention is to provide a water transfer film manufacturing method with 3D stereo effect and anti-counterfeiting function. The present invention solves the problem by adopting the following technical solutions:

A method for manufacturing a deplating water transfer film, comprising the steps of: printing a full version release layer on a PET film or an OPP film; hot pressing and embossing 3D embossing on the release layer; setting electroplating on the 3D embossing layer; coated with a resin pattern layer on the electroplating layer; wash off the electroplating layer outside the branch pattern layer with alkaline water; apply full version hot melt adhesive on the 3D embossing; compound PVA film on the hot melt adhesive; tear off Go to PET film or OPP film.

Preferably, a laser film is also provided between the hot melt adhesive and the PVA film.

Preferably, the release layer is one of polyethylene film, polypropylene film, polyvinyl chloride film and polyester film.

Preferably, the hot melt adhesive is EVA hot melt adhesive.

Preferably, the alkaline water is 10% by mass NaHCO ₃ solution.

The manufacturing method of the deplating water transfer film provided by the present invention can print patterns on irregular substrates such as planes and concave-convex surfaces, and has 3D three-dimensional effects, clear images, brilliant colors, and strong three-dimensional effect. It can be anti-counterfeiting, has a strong three-dimensional effect, and cannot prevent counterfeiting, which makes the product more competitive and has more added value.

Detailed ways

The present invention is described below in conjunction with experimental examples and examples, but the scope of protection of the present invention is not limited only to the following examples. Those of ordinary skill in the art can realize the object of the present invention according to the contents disclosed in the present invention.

Example 1

A kind of manufacture method of deplating water transfer printing film, comprises the steps:

Print a full-page polyethylene layer on PET (polyethylene terephthalate plastic) film, and use the polyethylene layer as a release layer;

Hot pressing and embossing 3D embossing on the release layer;

An electroplating layer is provided on the 3D embossing;

A resin pattern layer is coated on the electroplating layer;

Wash away the electroplating layer outside the branch pattern layer with alkaline water;

Apply full version hot melt adhesive on 3D embossing;

PVA (polyvinyl alcohol) film is compounded on the hot melt adhesive;

Tear off the PET film.

Example 2

A kind of manufacture method of deplating water transfer printing film, comprises the steps:

Print a full-scale polypropylene layer on OPP (o-phenylphenol) film, and use the polypropylene layer as a release layer;

Hot pressing and embossing 3D embossing on the release layer;

An electroplating layer is provided on the 3D embossing;

A resin pattern layer is coated on the electroplating layer;

Wash away the electroplating layer outside the branch pattern layer with alkaline water;

Apply full version hot melt adhesive on 3D embossing;

PVA (polyvinyl alcohol) film is compounded on the hot melt adhesive;

Tear off the OPP film.

In the above embodiment scheme, the release layer is printed on the PET film or OPP film. When the PET film or OPP film is torn off, the PET film or OPP film can be completely separated from the PVA film, and the pattern is transferred to the PVA film.

Moreover, PET film or OPP film has a clear rolling pattern and a strong three-dimensional effect, which avoids slow rebound after rolling.

Example 3

A kind of manufacture method of deplating water transfer printing film, comprises the steps:

Print a full-scale polypropylene layer on OPP (o-phenylphenol) film, and use the polypropylene layer as a release layer;

Hot pressing and embossing 3D embossing on the release layer;

An electroplating layer is provided on the 3D embossing;

A resin pattern layer is coated on the electroplating layer;

Wash away the electroplating layer outside the branch pattern layer with alkaline water;

Apply full version hot melt adhesive on 3D embossing;

There is a laser film on the hot melt adhesive;

PVA (polyvinyl alcohol) film is compounded on the laser film;

Tear off the OPP film.

In the scheme of the above-mentioned embodiment, the unnecessary electroplating layer is absorbed by alkaline water to realize the electroplating layer with different patterns on the 3D embossing, and the three-dimensional color or colorful color can be realized on the basis of the 3D effect, and it has a sense of electroplating; The laser film is added to the transfer film to realize the anti-counterfeiting function of the water transfer film.

As a partial alternative to the above embodiments, the release layer may also be one of polyvinyl chloride and polyester.

As a preferred solution of the above embodiments, the hot melt adhesive is EVA hot melt adhesive.

As a preferred version of the above embodiment, the alkaline water is 10% by mass NaHCO ₃ solution.

Transfer printing process of water transfer film:

1. Fill the sink with tap water;

2. Spread the water transfer printing film on the water surface, with the PVA film facing the water surface and the pattern facing upwards, let it stand still for about one minute, and the water temperature is about 30°;

3. The workpiece is pressed down toward the water surface at an oblique angle of 45° to expel the air, and the water transfer film will generate tension after the water dissolves, and the pattern on the water transfer film will be transferred to the product workpiece by the buoyancy of the water;

4. Wash the undissolved film residue on the water washing machine;

5. After baking, light oil (transparent resin) on the surface.

The embodiments of the present invention have been described in detail above, and specific examples have been used in this paper to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only used to help understand the method and core idea of the present invention; at the same time, for Those skilled in the art will have changes in the specific implementation and scope of application according to the idea of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
