Description

A sublimation heating-transfer color print MDF}

The present invention relates to a sublimation heat transfer color print MDF that is capable of color printing using a sublimation heat transfer paper on the MDF surface, and in particular, an adhesive function for sublimation heat transfer to an MDF surface consisting of a plane, a two-dimensional curved surface, and a three-dimensional curved surface. Sublimation thermal transfer color print MDF that enables high-quality color print MDF to be produced by quickly transferring various pattern colors such as natural wood grain and textile design using sublimation heat transfer paper having a releasability function to facilitate the removal of the sheet after transfer. It is about.

In general, MDF (Medium Density Fiberboard) is a wood plate product made by combining wood fiber obtained by dissolving at high temperature with wood as its main raw material with synthetic resin and molding and thermopressing it. It is uniform, dense and has no directivity unlike wood, allowing complex machining operations to be performed without rupture of the face or sides.

Then, various patterns or colors are transferred to the MDF surface and used for interior decoration of commercial buildings such as apartments, single-family homes, living rooms of officetels, department stores, general stores, and the like.

That is, in one example of the conventional transfer method applied to the MDF, after the adhesive treatment on the underlying MDF surface to form a thermal transfer layer of thermal transfer paper, and then forming a top clear undercoat layer on the surface of the thermal transfer layer The polishing is performed by coating the surface of the undercoating layer with top coat.

By the way, the transfer method is easy and simple to manufacture the thermal transfer paper of the thermal transfer print MDF, in order to perform the thermal transfer, the process of coating and drying the thermal transfer primer adhesive treatment on the surface of the MDF, and separate the top primer treatment after thermal transfer Due to the process of coating and drying process, the manufacturing process is complicated, so a lot of defects are generated, and the manufacturing time takes a long time.

On the other hand, in the case of another transfer method that improves the disadvantages of the transfer method, as a method of direct heat transfer directly to the MDF surface, the surface of the MDF with a patterned color thermal transfer paper formed with an adhesive layer and a top primer layer on the thermal transfer paper Direct thermal transfer on to produce a color print MDF.

Therefore, the transfer method has a merit that it can thermally transfer a large amount in a short time, but the process of manufacturing a thermal transfer paper is complicated and takes a lot of time accordingly. After applying the release layer and the release layer applied to the transparent upper primer layer is applied to the release layer, after forming a plurality of patterned ink layer and concealment layer on the surface of the upper primer layer, it can be adhered to the MDF surface Due to the adhesive manufacturing process, a lot of time and effort is required in manufacturing a thermal transfer paper due to a complicated manufacturing process, and there is a defect in that a bad factor occurs in this process.

Therefore, the present invention was devised to solve the above problems. Sublimation heat to improve the productivity and workability by improving the pattern color coating process of the MDF surface and to impart more improved functions to the MDF surface. The purpose is to provide a transfer color print MDF.

The present invention for achieving the above object is an MDF made of fibrous plywood having a density of 500-800 and a planar, three-dimensional curved surface, two-dimensional curved surface to the surface; and epoxy on the surface of the MDF Reinforced coating layer to form MDF resin layer surface by coating with oily and water-based coating agent selected from acrylic, urethane, enamel, melamine, polyester, and alkyt resin in gloss colorless or matte color; and the surface of the reinforcement coating layer Agitated celluloids, acrylic resins, additives, and sublimation dyes to impart adhesion and release properties for sublimation heat transfer, as well as printing patterns on the surface of the MDF resin layer using a copper plate for gravure printing in which various patterns are electronically sculpted. Sublimation thermal transfer paper forming a printed layer is sublimated thermal transfer so that the printed layer is about 2-100㎛ by the sublimation thermal transfer into the MDF resin layer surface. This penetration is formed while having a certain thickness enthalpy of sublimation transfer layer; And a sheet attached to the sublimation heat transfer layer to protect the sublimation heat transfer layer.

That is, in the case of the sublimation thermal transfer color print MDF, the sublimation heat transfer paper is attached to the resin layer to be subjected to the sublimation heat transfer, so that the sublimation heat transfer layer is formed on the MDF resin layer to be transferred, and the sublimation heat transfer layer has an adhesive function for sublimation heat transfer. MDF resin layer having a releasable function to facilitate the removal of the sheet after sublimation heat transfer, and formed of a printing layer formed on the surface of the MDF resin layer about 3-10 μm, and the sublimation heat transfer layer reinforced coating Sublimation heat transfer is performed by sublimation heat transfer of the pattern color of various patterns utilizing natural wood grain and textile design on the surface of MDF resin layer by being formed on the plane, three-dimensional curved surface and two-dimensional curved surface in the slope.

Therefore, it is possible to produce high quality color print MDF by sublimation heat transfer of various pattern colors by using sublimation heat transfer paper on the MDF resin layer surface, and improve productivity and workability by improving the pattern color coating process of MDF. The sublimation heat transfer paper forming the pattern color on the MDF is more easily manufactured, and the structure is simplified, thereby reducing the effort and time for manufacturing the sublimation heat transfer paper, and the production process of the color print MDF. This simplification reduces the manufacturing cost and prevents environmental pollution such as water pollution and air pollution generated during the production of color print MDF by using a pollution-free sublimation thermal transfer paper.
