Description

FLOORING MATERIALS

More particularly, the present invention relates to a flooring material in the form of a steel floor, which is excellent in environmental friendliness and abrasion resistance and is capable of transfer printing (embossed embossing), thereby securing market price competitiveness.

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 is soft PVC sheet because of its excellent processability and flexibility.

However, there is a need to develop eco-friendly materials due to the toxicity of human beings due to various additive materials added for the processing of PVC, such as plasticizers, viscosity reducing agents, organic solvents and the like.

Particularly, in the case of floorboards requiring a certain thickness and abrasion resistance, simple PVC alone can not satisfy required characteristics.

For example, the most commonly used flooring is a high-pressure laminate (HPL) laminated on a plywood plate, which is developed by collecting only the merits of a plywood floor.

However, the conventional steel floor has a low wear resistance due to the absence of a separate coating layer for maintaining wear resistance, and thus has a low scratch resistance, resulting in poor surface quality and poor durability during use.

In other words, it has come to the limit that it can not substitute for the steel flooring market, which is becoming more functional and diversified with only the plate and HPL laminating structure.

In recent years, efforts have been made to improve the latent heat level and durability by borrowing HPM (High Pressure Melamine sheet) instead of HPL, but the improvement is still needed.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is an exemplary layer structure view showing one embodiment of a flooring material according to the present invention. Fig.
2 is an exemplary layer structure view showing another embodiment of the flooring 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.

As illustrated in FIG. 1, a preferred embodiment of the flooring according to the present invention comprises a laminate layer 100 which forms the bottom layer that is the base.

The plywood layer 100 is determined within a thickness range of 6-8 mm and has a plywood structure in which 3-5 Ply is staggered in width or lengthwise direction to prevent expansion and contraction.

An adhesive layer 110 is formed on the plywood layer 100.

The adhesive layer 110 should be capable of maintaining sufficient adhesive strength even when used for a long period of time while increasing the adhesive strength.

Therefore, the PUR hot melt method is applied to form an adhesive layer, and the use of the water-based adhesive is not limited. However, since the water-based adhesive is weak to moisture, the adhesive strength is lowered during long-term use.

Here, the PUR hot melt adhesive type adhesive is melted at a working temperature of about 120-140 DEG C using a reactive urethane adhesive that is reactive PUR, has a viscosity of about 13,000 mPas and a density of about 1.1 g / cm3.

A glass fiber impregnated layer 120 is formed on the adhesive layer 110.

The glass fiber impregnated layer 120 is used to prevent the shrinkage and expansion of the product to maintain the dimensional stability. When the glass fiber is used, the contraction and expansion rate of the glass fiber can be reduced to about 0.01%.

In particular, the glass fiber impregnated layer 120 is a layer coated with a glass fiber impregnated with a PVC sol.

At this time, the composition ratio of the glass fiber and the PVC sol can be adjusted by adjusting the glass fiber within the range of 20-80 wt%.

That is, when 20 wt% of the glass fiber is used, the PVC sol is 80 wt%, and when the glass fiber is used at 80 wt%, the PVC sol is 20 wt%.

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, when it is added in an amount of more than 80% by weight, the coating property and the impregnation property are abruptly decreased to fail to perform the function. When the amount is less than 20% by weight, shrinkage and expansion inhibiting ability are rapidly decreased.

A transfer printing layer 130 is formed on the glass fiber infiltration layer 120.

The transfer printing layer 130 is a layer for developing patterns, and is a layer in which patterns are printed by a transfer method.

At this time, the transfer printing layer 130 has excellent realism and expressiveness according to the application of a tuning emboss, and thus has excellent printing properties as compared with HPL for a conventional flooring or LVT for a direct printing type.

In addition, a transparent upper layer 140 is formed on the transfer printing layer 130.

The transparent upper layer 140 is provided to enhance the hardness to improve the durability and to enhance the protective function of the transfer printing layer 130.

In this case, the transparent upper layer 140 may be formed by adding 10 to 40 parts by weight of a plasticizer to 100 parts by weight of PVC to improve coatability and improve environmental friendliness.

For this purpose, DOTP is suitable for the plasticizer.

A surface coating layer 150 is formed on the transparent upper layer 140.

The surface coating layer 150 may have various shapes depending on the application. For example, the surface coating layer 150 may be configured to maximize the actual flooring effect by lowering the glossiness by applying a polar coating. Alternatively, Functional materials may be added in a large amount, functional materials may be added to increase surface stain resistance, that is, antifouling properties, and the composition of the additives may be adjusted so that all of these properties can be realized.

As a preferred example according to the present invention, 5 to 20 parts by weight of a UV quencher having a particle size of 1-20 μm is added to 100 parts by weight of PVC to reduce the surface gloss to 15 ° or less, The surface coating layer 150 may be formed.

That is, since the main component of the surface coating layer 150 should have good compatibility with the transparent upper layer 140, it is natural PVC.

Further, in order to increase the scratch resistance on the surface, 5-15 parts by weight of the jade powder or amethyst powder may be added to the 100 parts by weight of the PVC, or 5-15 parts by weight of the mixed powder obtained by mixing them at a weight ratio of 1: 1 have.

At this time, it is preferable that the particle size of the jade or amethyst powder is also in the same range as that of the UV quencher.

In addition, in order to increase the antifouling property, 2-4 parts by weight of montmoronilonite and 2-4 parts by weight of Ds may be further added to 100 parts by weight of the PVC. The monomonylonite is an inorganic filler, , And Ds (Dichlorodimethylsilane) is a substance having strong hydrophobicity and is added for the purpose of improving antifouling function.

In addition, 3 to 6 parts by weight of calcium stearate may be added to 100 parts by weight of PVC, which promotes the lubrication function as a dispersant to induce homogeneous dispersibility of the additives.

In addition, as shown in FIG. 2, a non-foamed sheet layer NS may be further formed between the adhesive layer 110 and the glass fiber infiltrated layer 120.

It is preferable that the non-foamed sheet layer NS is composed of a PVC sheet as a layer for preventing impression and impression.

When such a layered structure is provided, the abrasion resistance, scratch resistance and antifouling function are enhanced by enhancing the surface while maintaining excellent dimensional stability compared to the existing HPL, the environmentally friendly property is increased, the manufacturing cost can be reduced, It is expected that it will be able to express the function and increase purchasing power as well as functionalization.
