MULTI COAED WINDOW AND METHOD FOR MULTI COATING THEREOF

The present invention relates to a multi-coated window and a multi-coating method thereof to beautifully implement various colors and designs in a window of a mobile terminal.

BACKGROUND ART In general, the use of plastic moldings is gradually increasing in the fields of cosmetic cases, portable terminal cases, windows, automobiles, electronic equipment and the like.

These products have a lower surface durability and hardness than glass or metal, resulting in a loss of commodity value. Various coating techniques have been developed to protect the surface damage and improve the hardness gloss of such plastic molded products. The most widely used coating techniques include natural drying methods, low temperature baking methods, UV curing methods, and the like.

As such, the type of paint applied to each material varies depending on the characteristics of the plastic material (difference in glass transition temperature for each material, difference in solvent power due to organic solvent, etc.). Due to the limited type of top and top coats suitable for each plastic material, it has a problem in improving productivity and paintability.

The paint applied to the plastic material as described above forms the coating film by applying the coating composition to various plastic materials, and forms a top coat by coating an ultraviolet curable paint thereon.

The window provided in the mobile terminal is produced by injecting an acrylic translucent resin for each color in the initial stage to produce an acrylic transparent injection base material, and coating a coating material for UV coating on the surface of the prepared transparent injection base material. do.

The UV coating paint is composed of only a transparent matte clear without matting agent and an opaque matte clear with matting agent and cannot express a translucent color, and is used only as a paint expressing gloss while protecting the base coating color. Only the glaze paint is applied to the window surface of the portable terminal.

The acrylic transparent injection base material mainly consists of a window of a mobile terminal.

However, the window of the conventional mobile terminal is made of acrylic material capable of withstanding transmittance and external impact, and in order to implement various colors of the window, a translucent resin for each color is secured, and the resin for each color is separately provided. Because there is a problem that must be injected, it takes a lot of time when injection, and if a different color is required, the resin must be replaced, and there is a problem that a defect such as foreign substances or stains generated during replacement occurs.

In addition, the conventional paint was developed only for color protection, so it can not implement a variety of other colors and texture of the surface had a disadvantage that the exterior design of the window is not beautiful.

The present invention is to provide a multi-coated window and a multi-coating method thereof to multiply the windows of the mobile terminal to realize various colors, thereby to vary the color of the window and to enhance the design.

In addition, the present invention provides a multi-coated window and its multi-coating to realize the effect of the mirror (mirror) and high reflection coating on the surface of the window by multi-coating (Multi Coating) to implement a variety of colors on the window of the mobile terminal To provide a method.

In addition, the present invention by multi-coating (Multi Coating) to implement a variety of colors in the window of the mobile terminal, to implement the electrolessness of the color, reflection change and metal feeling according to the viewing angle of the light incident on the surface of the window A multi-coated window and its multi-coating method are provided.

The present invention, the first coating layer surface-treated with a printing film of various colors on the front surface of the window base material;

A second coating layer for multi-coating the first coating layer; And

It characterized in that it comprises a third coating layer to the primer and hard coating on the second coating layer.

In addition, the multi-coating material is characterized in that consisting of titanium dioxide (Tio2), silicon dioxide (Sio2).

In addition, the primer coating (Primer Coating) is characterized in that the coating to a thickness of 20㎛.

In the window coating method,

A first step of surface-treating the front part of the window base material;

A second step of washing the window base material from the first step,

A third step of multi-coating the surface of the window base material from the second step;

A fourth step of primer coating from the third step,

A fifth step of first drying from the fourth step,

A sixth step of hard coating from the fifth step,

A seventh step of secondary drying from the sixth step, and

And an eighth step of irradiating ultraviolet rays from the seventh step.

In addition, the front surface of the window base material in the first step is characterized in that the printing film of various colors are coated.

In addition, the multi-coating material in the third step is characterized in that consisting of titanium dioxide (Tio2), silicon dioxide (Sio2).

In addition, the primer coating (Primer Coating) in the fourth step is characterized in that the coating to a thickness of 20㎛.

As described above, according to the multi-coated window and the multi-coating method thereof according to the present invention,

According to the present invention, by multi-coating the window of the mobile terminal to implement various colors, the color of the window may be varied, the design may be beautiful, and the effect of the mirror and the high-reflection coating may be realized on the surface of the window.
