Description

{FLOORING MATERIALS USING WPC}

The present invention relates to a reinforced floorboard using WPC, more particularly, to a reinforced floorboard using WPC having high moisture resistance, excellent dimensional stability, abrasion resistance, light weight, high strength and high durability.

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.

In addition, these types of steel floors have drawbacks that are vulnerable to moisture, and have limitations in that they are less resistant to bending and stamping.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to obtain a reinforced flooring material using WPC having excellent moisture resistance, excellent dimensional stability, abrasion resistance, light weight, high strength and high durability.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exemplary layer structure view showing an embodiment of a reinforced flooring using WPC according to the present invention. FIG.

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, the reinforced flooring using WPC according to the present invention includes a WPC (Wood Plastic Composite) layer 100 as a base layer.

The WPC layer 100 is prepared by mixing 40 to 60% by weight of any one of PP, PVC, and PE and 40 to 60% by weight of wood powder and then blending them and then extruding or blending them into a plate using a double belt press It is easy to understand if it is a sort of sheet material.

At this time, the WPC layer 100 has a protrusion formed on a side surface thereof and a groove portion formed on the opposite surface thereof to be engaged with the protrusion, so that the click structure is interdigitated and assembled, thereby enhancing convenience in assembly and assembly, It is more preferable to increase the stability.

When the wood powder constituting the WPC layer 100 is more than 60% by weight, the viscosity thereof increases sharply and the extrudability and formability deteriorate. When the wood powder is added at less than 40% by weight, strength and hardness can not be obtained, .

In addition, calcium carbonate as a filler and oleic acid amide as a lubricant are further added in an amount of 3-6 parts by weight based on 100 parts by weight of WPC constituting the WPC layer 100, in order to improve workability and increase extrusion moldability .

An adhesive layer 110 is formed on the WPC 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, it is preferable that the adhesive layer is formed by applying the PUR hot melt method, the conventional aqueous adhesive does not exhibit the adhesive force, and the oily adhesive agent is remarkably deteriorated in workability.

Here, the PUR hot melt adhesive layer is melted at a working temperature of 120-140 占 폚 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 depending on the characteristics of the glass fiber within the range of 30-50 wt%.

That is, when the glass fiber is used in an amount of 30 wt%, the PVC sol is 70 wt%, and when the glass fiber is used in an amount of 50 wt%, the PVC sol is 50 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, if it is added in an amount of more than 50% by weight, the coating property and the impregnability tend to fall off rapidly and the function of the composition is not achieved. When the amount is less than 30% 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 printability compared to the LVT transfer paper, which is an existing direct printing method, because it has excellent realism and sense of expression according to the application of the emboss emboss.

In particular, it has an advantage that the depth of wood embossing can be deepened to improve the surface touch sensitivity when a general emboss is applied.

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 top layer 140 may be formed by adding 10 to 50 parts by weight of a plasticizer to 100 parts by weight of PVC to improve coatability and enhance 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 contain a large amount of a functional material for enhancing scratch resistance in the surface, and may also contain a functional material May be added, and the additive composition may be adjusted so that all of these characteristics can be realized.

For example, 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 mixture powder in which the weight ratio of them is 1: 1 have.

At this time, the particle size of the jade or amethyst powder is preferably 0.1-0.3 mu m.

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

In addition, the surface coating layer can further increase scratch resistance by further containing 1 to 50 parts by weight of aluminum oxide per 100 parts by weight of PVC.

Further, 10 to 60 parts by weight of urethane acrylate as an oligomer and 20 to 50 parts by weight of an acrylate monomer as a monomer may be further added.

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.

By providing a layered structure in this form, it is possible to increase the abrasion resistance, scratch resistance and antifouling function through surface strengthening while maintaining excellent dimensional stability compared to the existing flooring materials, increase the environmental friendliness, It is expected that it will be able to express the function and increase purchasing power as well as functionalization.
