The present invention relates to a synthetic resin foil decorative material and a method of manufacturing the same, showing a wood pattern effect with a colored aqueous ink, and more particularly, to a synthetic resin floor decoration material having a natural wood pattern effect with excellent durability.

In recent years, as the income level has increased, interest in convenience and fashion has increased, and the trend of demanding practicality, durability, and appearance of flooring materials used in residential and commercial spaces has been increasing. .

Although flooring materials used in actual residential and commercial spaces provide functions such as durability, practicality and fashion, the flooring materials actually used are fashioned through composition-type flooring materials and printed patterns that give durability and practicality. It is a situation that the flooring of the print type to give the castle.

In detail, the conventional floor decorative material is a composition type that gives durability and practicality, but the color change of the appearance by the color chip is possible, but it was difficult to express the natural decorative effect and only a monotonous shape could be obtained.

In addition, in order to solve this problem, as shown in FIG. 3, the printed pattern is directly printed on the vinyl chloride transparent resin layer 5, or the vinyl chloride transparent resin layer 5 is placed on top of the printed layer 3 separately. And the surface treatment layer (6), the base material layer (4) to the plywood down to give fashion, but when printing one type of pattern form plywood and then cut the plywood to be installed on the floor, the same pattern is repeated Since the pattern is uniform in overall, it gives a natural appearance by giving an unnatural and artificial feeling.

In addition, in the case of the manufacturing method of the tile by printing, there is a problem that the surface is worn by the friction caused by walking and the decoration carved on the surface is lost.

 In order to solve this problem in the prior art, when manufacturing a floor decorative material that creates a wood effect, one or more colored aqueous inks are coated on the base layer, and then pulverized, and the crushed amorphous chips are rolled at an appropriate rolling ratio. By embossing, the present invention has been completed by focusing on the practicality and fashion by providing a variety of natural wood pattern effects to the flooring material while removing artificial feeling with excellent durability.

Accordingly, the present invention solves the problem of loss of marble shape due to abrasion of the surface layer of the conventional flooring material, the problem of unnatural, uniform and artificial pattern of the pattern, the problem of having a monotonous and easily patterned pattern by color with color chips. Its purpose is to provide a flooring material having an appearance that is not easily planted by maximizing the effect of natural wood pattern by maximizing the natural wood pattern effect and providing durability and naturalness and various patterns. .

The flooring material of the present invention for achieving the above object is a composition type in which one or more colored aqueous inks having a color similar to wood is mixed with a wooden-colored base layer, and coated with a colored aqueous ink on the base layer. Then, by rolling the crushed chip, the wood pattern marble formed by the colored aqueous ink is penetrated from the surface to the rear surface based on the base layer, and is preferably characterized by three-dimensional impression by embossing.

In order to protect the surface of the wood pattern marble sheet and to provide durability in the present invention, photocurable urethane acrylic resin or water-based urethane resin is preferably coated on the wood pattern marble sheet to form a surface treatment layer.

The colored aqueous ink used in the present invention uses one or more kinds of wood-like colors, which give a very natural effect in forming the wood pattern.

The method of manufacturing a flooring material according to the present invention comprises the steps of coating and pulverizing one or more colored aqueous inks having a color similar to wood to a base layer of wood color; Rolling the crushed amorphous chip with a primary calender to produce a wood pattern marble sheet; And re-rolling the wood pattern marble sheet with a secondary calender to form a natural wood pattern marble.

Preferably, the method further includes an embossing step of imparting a wood pattern embossing to impart a three-dimensional feeling and naturalness of the wood pattern. In addition, in order to protect the surface of the wood pattern sheet and impart durability, further comprising the step of forming a surface treatment layer by coating a photocurable urethane acrylic resin or an aqueous urethane resin on the wood pattern marble sheet.
