Description

LOOSE LAY TILE

More particularly, the present invention relates to a lustrous tile having improved durability and dimensional stability while improving surface scratch resistance and surface stain resistance when used as a flooring, and having improved ease of installation.

In general, flooring materials (including flooring) are mainly made of wood, and eco-friendly flooring materials are being introduced for the purpose of blocking the moisture on the concrete floor and blocking hazardous materials along with the development of housing, especially apartment culture.

The most common flooring material, the floor tile, is a soft PVC sheet because of its excellent processability and flexibility.

However, in the case of a flooring material having a certain thickness and requiring abrasion resistance, that is, a floor tile, simple PVC alone can not satisfy the required characteristics.

Recently, LVT (Luxury Vinyl Tile) and the like have been disclosed.

Since LVT is made of the most expensive vinyl material among PVC, it has a very good durability. In addition, since it is applied by using an adhesive, it is also excellent in non-slip property.

However, in the case of LVT, there is a disadvantage in that it is hard to remove once it is applied because it is applied by fixing using an adhesive, and maintenance is difficult and the workability is very bad.

This is not a limitation of LVT but is a disadvantage which is applied to most loose lay tiles which are developed to increase non-slip property.

In addition, since the surface of the conventional loose-rail tile does not have a separate coating layer, scratch resistance is weak, and contamination easily occurs. Therefore, it is necessary to maximize the antifouling property to ensure ease of use and ease of cleaning.

2 is an exemplary layer structure diagram showing another embodiment of the lustry tile according to the present invention.
3 is an exemplary layer structure view showing another embodiment of the rust pattern according to the present invention.

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

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

In addition, 'G / F' described below means glass fiber.

1, a preferred embodiment of the lustrous tile according to the present invention includes a bottom plate 100 as a base layer and a top plate 200, which is laminated to the bottom plate 100 and forms an upper surface of the tile. .

The lower plate 100 includes a balance layer 110 contacting the bottom surface, a base layer 120 laminated on the balance layer 110, and a lower G / F impregnated layer 120 laminated on the base layer 120. [ (130) and a center layer (140) laminated on the lower G / F impregnated layer (130).

Since the balance layer 110, the base layer 120, the lower G / F impregnated layer 130, and the center layer 140 all contain a PVC component, the balance layer 110, By heating and pressing, it is possible to laminate without a separate adhesive.

Particularly, since the present invention is processed in the form of re-laminating two plates after separation and manufacture with the lower plate 100 and the upper plate 200, it is possible to maximize the production efficiency by doubling the plate size to twice the original size , Which is possible because it is possible to reduce the weight of each plate by half because it is divided by half the thickness of the tile thickness, which makes it easy to press and process.

The balance layer 110 is a PVC sheet layer for curling tiles and should have a specific gravity of 1.4-1.8 in order to enhance anticurlability.

Of course, a sol-geling layer or a foam layer may be further provided on the lower surface of the balance layer 110 according to the characteristics of the bottom surface to which the tile is to be applied.

At this time, the sol-gel ring layer is a PVC sheet layer to enhance non-slip property, and the foam layer is a foam sheet layer in which PVC or polypropylene resin is foamed to enhance an acoustic function.

In addition, the PVC sheet used in the present invention is preferred because it is easy to process, has a low processing cost, and can be easily formed by continuously rolling the embossing process on the white surface.

In addition, the base layer 120 is a PVC sheet layer produced using an INTENSIVE MIXER (BANBURY MIXER), minimizing shrinkage deformation between the lower G / F impregnated layer 130 and the balance layer 110 while adjusting the thickness of the tile .

Therefore, the base layer 120 should be adjusted to have a total specific gravity of 1.5 or more by adjusting the amount of filler (e.g., calcium carbonate) added.

The lower G / F impregnated layer 130 is provided to maintain the dimensional stability of the tile, and is a PVC sheet layer impregnated with a glass fiber.

In other words, if PVC is impregnated with glass fiber, shrinkage expansion rate can be reduced to about 0.01% compared to existing luster tile.

In particular, it is preferable that the impregnation of the glass fiber is made to be impregnated with the PVC sol, and the content of the glass fiber should be 20-80 g per 1 m2 of the PVC sheet forming the lower G / F impregnated layer 130 .

Here, the higher the content of the glass fiber is, the stronger the property of preventing shrinkage and expansion, and the dimensional stability is improved while the durability is improved. However, if it exceeds 80 g per 1 m 2, the coating property and the impregnation property will be abruptly lowered to fail to perform its function. If the addition amount is less than 20 g per 1 m 2, shrinkage and expansion inhibiting ability will be drastically decreased.

The center layer 140 forms a middle layer between the upper plate 200 and the tile at the time of plywood and is disposed at the upper portion with the lower G / F impregnated layer 130 interposed therebetween, The total specific gravity should be maintained at 1.5 or more, preferably the same specific gravity as that of the base layer 120, by controlling the addition amount of the filler as in the case of the base layer 120.

The upper G / F impregnated layer 210 is the same as the lower G / F impregnated layer 130 described above, and the transfer printing layer 220 is a layer for developing a pattern. In the transfer method, Lt; / RTI > The pattern can be various forms such as a pattern of wood, an emboss.

In addition, a transparent upper layer 230 is attached to the upper portion of the transfer printing layer 220. The transparent upper layer 230 is a sheet having transparency, which increases hardness to improve durability, Layer 220 to enhance the protection function of the layer 220.

In this case, the transparent upper layer 230 may be formed by adding 10 to 40 parts by weight of a plasticizer to a transparent PVC sol based on 100 parts by weight of the transparent PVC sol to improve coatability and improve environmental friendliness. DOTP is a suitable plasticizer.

A UV coating layer 240 is formed on the transparent upper layer 230.

The UV coating layer 240 may have various shapes depending on the application. For example, the UV coating layer 240 may contain a large amount of a functional material for adjusting the gloss or enhancing scratch resistance on the surface, May be added, and the additive composition may be adjusted so that all of these characteristics can be realized.

In the present invention, the UV coating agent for forming the UV coating layer 240 may include 20 to 40% by weight of a monoester, 10 to 20% by weight of an oligomer, , 10-20% by weight of polyethylene glycol diacrylate (PEGDA), 10-20% by weight of silicon (Silicon), and the balance filler.

In addition, a UV quencher having a size of 1 to 20 mu m may be further added to obtain an effect similar to that of an actual floor by lowering the gloss, so that the gloss is not more than 15 DEG.

In order to enhance the scratch resistance, a jade powder or amethyst powder having diameters of 1-20 μm or diamonds is added to the UV coating liquid constituting the UV coating layer 240 in an amount of 0.01-10 parts by weight based on 100 parts by weight of the UV coating liquid Can be added.

In addition, the luster tile having the above-described layered structure may have a rectangular shape, and may have a click-locking structure as well as all sides, that is, the peripheries are right-angled.

Here, the click-locking structure is a patented technology that is gained by a floor material manufacturer, such as Valgee or Unilin, in which protrusions are formed on one side of the lustrile tile and the protrusions are pivoted Which is formed to be pivotally assembled with each other.

2, a transparent underlayer 202 may be further formed under the upper G / F impregnated layer 210 of the upper plate 200 to improve the lamination force during post-processing.

In this case, the post-processing means a process of laminating the lower plate 100 and the upper plate 200. The transparent lower layer 202 is composed of a transparent PVC sol and 15 to 40 parts by weight of a plasticizer and 100 parts by weight of a filler 40 By weight or less, and the resulting mixture is molded into a sheet to form a plywood.
