As used herein, the singular forms “a,” “an,” and “the” include plural forms as well, unless the phrases clearly indicate the opposite. As used herein, the meaning of “comprising” specifies a particular characteristic, region, integer, step, operation, element, and / or component, and other specific characteristics, region, integer, step, operation, element, component, and / or group. It does not exclude the presence or addition of.

Hereinafter, with reference to the accompanying drawings will be described for a building material and a manufacturing method according to an embodiment of the present invention.

First, a building material according to an embodiment of the present invention will be described with reference to FIG. 1.

Referring to FIG. 1, the substrate 10, the substrate layer 30 attached to the upper surface of the substrate 10 by the adhesive layer 20, and the pattern sheet 40 attached on the substrate layer 20. And an olefin sheet 50 positioned on the upper surface of the pattern sheet 40.

The substrate 10 is a layer made of plywood or wood-based boards such as MDF (medium density fiberboard), inorganic boards such as gypsum board or magnesium board, or synthetic resin board made of synthetic resin. To achieve.

The base material layer 30 is a layer for increasing the adhesive force with the patterned sheet 40 located thereon, and is made of kraft paper.

In this case, the kraft paper may be a resin impregnated kraft paper impregnated with a resin for a predetermined time.

The resin used for the resin solution impregnated with kraft paper may be a phenol resin, an acrylic resin, an epoxy resin, a polyvinyl acetate (PVAc) resin, a melamine resin, a urea resin, a urethane resin, or a PVA (poly vinyl alcohol) resin.

This base material layer 30 is adhered to the upper surface of the substrate 10 by the adhesive layer 20 as described above.

As such, the adhesive used to adhere the substrate layer 30 onto the substrate 10 may be a thermosetting adhesive, a thermoplastic adhesive, or a room temperature curing adhesive.

At this time, since the lower surface of the base material layer 30 on which the adhesive is applied to form the adhesive layer 20 has an uneven surface, the adhesive force with the substrate 10 is improved, so that the base material layer 30 and the substrate 10 Peeling phenomenon is greatly reduced. Therefore, the life of the building material of the present example is increased, and the user's satisfaction is improved.

 In this case, the uneven surface of the base layer 30 may be formed using a sanding method using a sander, a sandblasting method, a corona process, or the like.

The weight of the base layer 30 may be 150g / m 2 ~ 300g / m 2 .

However, in an alternative example, the bottom surface of the substrate layer 30 may have a flat surface rather than an uneven surface.

The pattern sheet 40 is a layer for determining the pattern of the building material exposed to the outside is a sheet is printed a variety of patterns, such as wood pattern.

Since the adhesive is impregnated on the lower surface of the pattern sheet 40, the pattern sheet 40 is directly attached to the upper surface of the substrate layer 30 without the need to apply an adhesive on the upper surface of the substrate layer 30. The pattern sheet 40 is positioned on the base layer 30.

However, in an alternative example, the pattern sheet 40 may not be impregnated with an adhesive, and in this case, a separate adhesive coating operation may be performed on the upper surface of the base layer 30.

The olefin sheet 50 is a transparent sheet, and the pattern of the pattern sheet 40 disposed below is exposed to the outside.

The olefin sheet 50 includes a sheet base layer 53, an adhesive layer 51 located on the bottom surface of the sheet base 53, and a coating layer 55 located on the top surface of the sheet base layer 53.

The sheet base layer 53 may be made of polyethylene, polypropylene, or polyethylene terephthalate (PET).

The adhesive layer 51 is a layer for attaching the sheet base layer 53 to the upper surface of the pattern sheet 40 and is formed by application of an adhesive. At this time, the adhesive used may also be a thermosetting adhesive or a thermoplastic adhesive.

The adhesive layer 51 may perform a function of a flooring primer to uniformize the state of the lower surface of the sheet base layer 53 and protect the sheet base layer 53 so that the lower pattern sheet 40 Adhesion state and adhesive force with can be improved.

For the privacy function, the adhesive layer 51 may be formed using a polyurethane (PU, PolyUrethane) material, an unsaturated polyester (UPE, Unsaturated polyEster) material, or a hot melt material. Coating layer 55 is a layer forming the top layer of the building material of the present example to minimize the occurrence of scratches due to external impact or force and smooth the surface.

The coating layer 55 of the present example is a UV coating that blocks ultraviolet rays (UV), and prevents discoloration or yellowing or browning of building materials due to ultraviolet rays.

Due to the coating layer 55, the pattern printed on the pattern sheet 40 located at the bottom is exposed to the outside more vividly and naturally to make the building material high-quality, and also the building material is not easily deformed or bent and is resistant to moisture. Durability and service life are improved.

As described above, the building material of the present example uses an olefin sheet made of environmentally friendly olefins as a finishing material instead of a sheet made of PVC (pernicious vile compound) in which toxic substances such as dioxins are discharged. No discharge is made.

In addition, since the olefin sheet 50 is attached onto the substrate 10 via the substrate layer 30 made of kraft paper containing the resin component, the phenomenon in which the olefin sheet 50 is peeled off from the substrate 10 is greatly increased. Decreases.

That is, since the base material layer 30 of this example consists of resin impregnated kraft paper containing a resin component, the adhesive force between the olefin sheet 50 and the base material layer 30 and the base material layer 30 by the resin component contained in a kraft paper ), The adhesion between the substrate 10 and the substrate 10 is further improved, so that the phenomenon in which the olefin sheet 50 is peeled from the substrate 10 is greatly reduced. For this reason, the lifetime of the building material of this example increases.

In addition, as the adhesion between the olefin sheet 50 and the substrate layer 30 increases, the adhesion between the olefin sheet 50 and the olefin sheet 50 positioned between the olefin sheet 50 and the substrate layer 30 also increases. Done.

As a result, the sharpness of the pattern of the pattern sheet 40 projected to the outside through the transparent olefin sheet 50 is further increased.

In the building material shown in FIG. 1, one substrate layer 30 is located, but alternatively two or more substrate layers 30 may be located in succession.

In this case, the plurality of substrate layers 30 may be adhered to the substrate layers 30 adjacent to each other by using a heat treatment process or a separate adhesive.

The number of the base material layers 30 to be laminated may be determined according to the strength or thickness of the building material according to the use of the building material.

The manufacturing process for this building material of this example is demonstrated with reference to FIG.

As shown in FIG. 2, first, an adhesive is applied on the upper surface of the substrate 10 (S11), and then the base layer 20 having the uneven surface is positioned on the upper surface of the substrate 10 on which the adhesive is applied. (S13). At this time, the uneven surface of the substrate layer 20 is positioned in contact with the upper surface of the substrate 10.

Next, an adhesive-impregnated or unimpregnated pattern sheet 40 is attached to an upper surface of the substrate layer 20, that is, a flat surface opposite to the uneven surface, and the pattern is formed on the upper surface of the substrate layer 20. Position the sheet 40 (S15).

Then, after placing the olefin sheet 50 coated with the adhesive on the pattern sheet (40) (S17) is subjected to a heat treatment operation to cure the adhesive to form the adhesive layer (20, 51). At this time, the adhesive layer 51 may have a primer function.

In this case, the heat treatment process for the adhesive layer 20 51 may be performed a plurality of times to individually form the adhesive layers 20 and 51.

Also, in an alternative example, the coating layer 55 located on the top surface of the olefin sheet 50 may be formed through a separate process.

In other words, an adhesive is applied to the lower surface of the sheet base layer 53 to form a preliminary olefin sheet, and the preliminary olefin sheet formed is placed on the decor sheet 40, and then a coating agent is applied to the upper surface of the sheet base layer 53. After coating, the olefin sheet 50 including the adhesive layers 20 and 51 and the coating layer 55 may be formed through a heat treatment process to complete a building material. Of course, even in this case, the heat treatment operation may be performed a plurality of times in a separate process whenever necessary.

In the present example, when the adhesive uses a room temperature curing type adhesive, the heat treatment step for forming the adhesive layers 20 and 51 is omitted.

Next, a building material according to another embodiment of the present invention will be described with reference to FIG. 3.

Compared to FIG. 1, components having the same structure and performing the same function are given the same protection as those of FIG. 1, and detailed description thereof is also omitted.

The building material of this example shown in FIG. 3 includes a substrate 10, a substrate layer 30 positioned on the substrate 10, an adhesive layer 20 located between the substrate 10 and the substrate layer 30, and a substrate layer. Located above 30 and having a transparent olefin sheet 50a.

The building material of this example is not provided with a separate pattern sheet, but is provided with the pattern layer which printed the desired pattern on the upper part or the lower part of the olefin sheet 50a of this example.

Thus, as shown in FIG. 3, the olefin sheet 50a is the same as the olefin sheet 50 of FIG. 1, the sheet base layer 53, the adhesive layer 51 positioned below the sheet base layer 53, and The coating layer 55 is positioned on the sheet base layer 53.

In addition, the olefin sheet 50a of the present example includes a pattern layer 57 positioned between the coating layer 55 and the sheet base layer 53 or between the lower surface of the olefin sheet 53 and the adhesive layer 51.

The pattern layer 57 is a layer which coats ink and forms a desired pattern, and the pattern of the pattern layer 57 is reflected to the exterior of the olefin sheet 50a.

In this way, since the separate pattern sheet is omitted, the defective rate generated when the pattern sheet is attached is reduced, and the yield for the building material of the present example is improved.

Such building materials may be manufactured through one exemplary process such as FIG. 4.

That is, as shown in FIG. 4, the adhesive is applied on the upper surface of the substrate 10 (S21), and the base layer 30 having the uneven surface is placed on the upper surface of the substrate 10 to which the adhesive is applied. (S23). As already described, the substrate layer 30 is positioned on the upper surface of the substrate 10 so that the uneven surface adheres to the adhesive to increase the adhesive force between the adhesive and the substrate layer 30.

Then, the pattern layer 57 and the coating layer 55 is positioned and the olefin sheet 50a coated with an adhesive on the lower surface is placed on the base layer 30 (S25) and then heat treated to form an adhesive layer (20, 51) The base material layer 30 is adhered to the substrate 10 using the substrate, and the olefin sheet 50a is adhered on the base material layer 30 to complete the building material.

In an alternative example, the pattern layer 57 and the coating layer 55 are not formed, and the pre-olefin sheet having only an adhesive applied to the bottom of the sheet base layer 53 is first placed on the base layer 30 and then heat treated to form an adhesive layer. (20) to bond the substrate 10 and the base layer 30, and also to the pre-olefin sheet on the base layer 30 using the adhesive layer 51, and then to the upper surface of the pre-olefin sheet of the desired color The ink may be printed to form the printing layer 55 and the coating layer 55 may be formed again.

At this time, the heat treatment process for the formation of each layer (57, 55) and the adhesive operation using the adhesive (20, 51) may be performed at once or may be performed in a separate process as necessary.

As already described with reference to FIG. 1, the number of base layers 30 may also be at least one.

The building material according to the present embodiment can be used as a flooring material such as a flooring flooring.

In the above, the Example of the building material of this invention and its manufacturing method was demonstrated. The present invention is not limited to the above-described embodiment and the accompanying drawings, and various modifications and variations will be possible in view of those skilled in the art to which the present invention pertains.
