Floor decoration material having a wood flour print layer according to the present invention is a floor decoration material consisting of a plurality of resin layers including a general print layer, one side of the general print layer by wood chips according to the printed pattern of the general print layer It is characterized in that the wood powder printing layer is printed pattern.

In addition, according to the present invention, there is provided a method of manufacturing a floor decorative material having a wood flour print layer, in which a plurality of shapes of printing holes are formed in a circumferential surface of the floor decorative material in which a plurality of resin layers are laminated. A rotary screen formed by a cylindrical roll having a mark formed at one end thereof so as to display a wood flour printing layer forming process of forming a basic print pattern by distilling wood chips through the printing hole. It characterized in that it comprises a general print layer forming process to form an auxiliary print pattern suitably.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail.

2 is a longitudinal sectional view showing a flooring material having a wood flour print layer according to an embodiment of the present invention.

As shown in Figure 2, the glass fiber impregnated layer 11 impregnated with glass fiber (Plasma Fiber) PVC is formed on the upper side of the wood flour printing layer 13 is printed with a pattern by the wood chips, A transparent upper layer 15 is formed on the upper side of the wood flour printing layer 13 so as to protect the printing surface of the wood flour printing layer 13 and to project it, and an ink on the upper side of the transparent upper layer 15 The general printing layer 17 having a predetermined pattern and color is formed, and the transparent upper layer 19 is formed on the upper side of the general printing layer 17 so as to protect the printing surface of the general printing layer 17. The UV coating layer 21 is formed on the upper side of the transparent upper layer 19 to prevent the adsorption of contaminants and at the same time to prevent scratching, and the lower side of the glass fiber impregnation layer 11 is bufferable. Foam layer 23 is formed to have a, and the foam layer 23 is the lower side The fabric layer has a layer (Backing Layer) (25) is formed not so as to protect (23).

At this time, the basic powder pattern by the wood chips are formed in the wood flour print layer 13, and the secondary printed pattern is formed in the general print layer to match the basic printed pattern. Taking the petal as an example, the basic printed pattern corresponds to the outer shape of the petal and the stripes in the petal correspond to the auxiliary printed pattern.

The wood flour printing layer 13 is a layer printed with wood chip chips on the glass fiber impregnated layer 11, which is 50 to 60% of PVC resin and 20 to 30% by weight of wood flour (wood powder, etc.). , 15 to 20% by weight plasticizer, 2 to 5% by weight stabilizer, and various colors can be given.

The transparent layer 15, 19 is 100 parts of PVC Resin, 80-150 parts of plasticizer (Dioctyl Phthalate, Diisononyl Phthalate, Butyl Benzyl Phthalate, Texanoliso Butyrate, etc.), 1-5 parts of Ba-Zn-based stabilizer, UV absorber 0.1 It is composed of -2 parts.

The ink of the general printing layer 17 is an inorganic ink or a colored PVC Sol ink, wherein the inorganic ink is a pigment 1-8%, vinyl acetate binder 10-30%, a certain amount of solvent (methyl ethyl) Ketone, methyl isobutyl ketone, toluene, etc.), and the colored PVC Sol ink contains pigment 1-15%, PVC Resin 60%, plasticizer 30-60%, heat stabilizer 1-5%, and other additives. It is made up at 4%.

The ultraviolet coating layer 21 is made of a known ultraviolet photocurable resin (for example, photocurable urethane).

The foam layer 23 is 100 parts of PVC resin, 30-80 parts of a plasticizer (Dioctyl Phthalate, Diisononyl Phthalate, etc.), 3-10 parts of a foaming agent (Azo di Carbon amied), 1-8 parts of Ba-Zn-based stabilizer, filler 10 -50 parts, ZnO-based foamed Kicker 1-3 parts and the like are mixed.

The base layer 25 is made of PVC resin and has a softening agent having a polymerization degree of 1000 to 1300.

Hereinafter, a method of manufacturing a floor decorative material having a wood flour print layer according to a preferred embodiment of the present invention will be described in detail.

This flooring material is manufactured by a semi-finished product process, an intermediate process and a finishing process sequentially.

In the semi-finished product process, the glass fiber impregnated layer 11 is formed by impregnating PVC while releasing a glass fiber material from a roll and guiding it with a guide roller, and then sequentially forming the foam layer 23 and the base layer 25. It is laminated | stacked and it consists of the order which winds up on a roll.

In the intermediate process, as shown in FIG. 3, after unrolling the semi-finished product wound on the roll 31 and coating the adhesive on the upper side of the glass fiber impregnated layer 11 so that the wood chips are adhered, a rotary machine is used. The wood chips are discharged from the cylindrical roll 35 of the screen to form the wood powder printing layer 13, and then the transparent paper layer 15 is laminated on the wood flour printing layer 13 by the coating machine 37. 39).

The cylindrical rolls 35 used in the intermediate process are sequentially arranged to give various printed patterns, and as shown in FIG. 4, basic printed pattern shapes are formed on the circumferential surface of the plurality of printing holes 35a. Is formed and a mark mark 35b is formed at one end to indicate the position of the printing hole 35a. The wood chips are leaked through the printing hole 35a to form a basic printed pattern.

The finishing process is a general print layer 17 for forming an auxiliary print pattern to match the basic print pattern by locating the intermediate product formed with the basic print pattern on the roll 39 to guide the guide roller to position the mark 35b. ), And then the transparent upper layer 19 and the UV coating layer 21 are sequentially stacked on the upper side of the general printing layer 17, and then wound in a roll.

Printing of the general print layer 17 may be a variety of methods, such as known gravure printing, transfer printing, printing using a PVC sol screen.

The present invention is not limited to the above embodiments, and may be applied to flooring materials having various resin layers formed thereon. For example, in the present invention, the wood printing layer is formed on the lower side of the general printing layer, but as another embodiment of the present invention, the general printing layer and the wood powder printing layer may be stacked in a reversed structure.

According to the flooring material with a wood-printed layer and the manufacturing method thereof according to the present invention, it is possible to simply produce a natural texture and a variety of printed patterns, and to simply produce a three-dimensional effect by the separation of the basic printed pattern and the auxiliary printed pattern, The manufacturing cost is reduced compared to the three-dimensional image providing method by the conventional printing method and the embossing method.
