Description

Prefabricated flooring, and method of manufacturing the same {SECTIONAL FLOORING, AND METHOD FOR MANUFACTURING THE SAME}

The present invention relates to a prefabricated flooring material, and a method for manufacturing the same, and more particularly, the flooring material has excellent water resistance, moisture resistance, and lifespan characteristics, and has low noise due to adhesion at a bonding site after construction. And a method for producing the same.

The residential flooring market is changing due to the improvement of consumer's quality of life and improved consciousness. In other words, it is expanding from PVC material flooring materials, which are relatively inexpensive and easy to construct and use, to flooring materials such as solid wood, plywood, reinforced floor, and steel floor using eco-friendly materials.

All the flooring using the wood has the disadvantage that it is vulnerable to moisture and moisture. In Korea, where the four seasons are distinct, there is a problem in that the processed part of the flooring is swollen due to exposure to moisture or moisture, especially during the rainy season or in the summer when it rains a lot, or the flooring changes.

In particular, the reinforced floor consists of a thin layer within 0.2mm of the thickness of the laminated paper processed to give a solid wood texture, so that the 'V' cutting can be done by chamfering the edge of the upper part of the plate like a wooden floor at an inclined angle. The disadvantage is that it can't be. When cutting the reinforced floor 'V', the joint part of the paper is exposed, which makes it more vulnerable to moisture.

In addition, the reinforcement floor includes the laminated patterned paper, and there is also a problem of aesthetic feeling that, when chamfered at an inclination angle, the texture of the wood cannot be obtained because the materials between the layers are different from each other. Even if aesthetic treatment does not achieve full moisture resistance, moisture may penetrate and swell the edge cutting area, or dry and shrink, thereby accelerating the deformation of the flooring.

In order to compensate for the drawbacks of the reinforced floor, there is an example in which a material such as a water repellent, a waterproofing agent, or a wax is applied to the processing part of the flooring material. According to Korean Utility Model Registration No. 20-0362163, paint is applied to the processed part of the reinforced floor and dried, and the wax is coated on top of the paint layer again to solve the problem of flooring absorbing water and expanding or shrinking. One line registration scheme is known.

The acrylate-based polymer coating layer 140 improves the water resistance and moisture resistance of the flooring material 100, thereby preventing the appearance deformation due to moisture absorption of the flooring material 100, thereby extending the life of the flooring material 100. In addition, the acrylate polymer coating layer 140 prevents the appearance of the flooring material 100 from being altered even when the flooring material 100 is exposed to water for a long time or dried by heating.

The acrylate polymer coating layer comprises an acrylate polymer.

The acrylate polymer is acrylonitrile, methyl methacrylate, ethylhexyl acrylate, methyl acrylate, ethyl acrylate, 2-hydroxyethyl acrylate, 2-hydroxyethyl methyl acrylate, N-methylol acryl Acrylate, glycidylmethyl acrylate, butyl acrylate, acrylamide, n-propyl acrylate n-butyl acrylate, hexyl methacrylate 2-ethylhexyl methacrylate, and combinations thereof Preferably, the rate monomer is polymerized and formed.

The acrylate polymer preferably contains 10 to 70 parts by weight of the acrylate monomer, and 1 to 10 parts by weight of the α, β-unsaturated carboxylic acid monomer. When the acrylate polymer includes the α, β-unsaturated carboxylic acid monomer in the above range, it is preferable in that thermal stability, chemical stability, mechanical stability, and water resistance increase.

The acrylate polymer coating layer is preferably a styrene-butadiene-acrylate copolymer coating layer.

In addition, the styrene-butadiene-acrylate copolymer coating layer may be prepared by polymerizing an acrylate monomer and a styrene monomer and a butadiene monomer. When the acrylate polymer further comprises the styrene monomer and the butadiene monomer, it is preferable in that the adhesive force is increased and the noise reduction effect due to the viscoelastic character is increased.

The acrylate polymer is preferably 1 to 70 parts by weight of the acrylate monomer, and 1 to 70 parts by weight of the styrene monomer and butadiene monomer, 5 to 40 parts by weight of the acrylate monomer, and It is preferable to include the styrene monomer and butadiene monomer 10 to 55 parts by weight.

When the content of the acrylate-based monomer, and the styrene monomer and the butadiene monomer is in the above range, the water resistance of the styrene-butadiene-acrylate copolymer coating layer is improved, the adhesion and noise prevention effect is greatly increased is preferable. When the content is out of the above range, floorboard reconstruction work is not possible due to excessive adhesive force, and floorboard lifting may occur due to a decrease in water resistance and thermal stability.

When the weight ratio of the styrene monomer and the butadiene monomer is within the above range, it is preferable in that the water resistance and adhesion of the coating layer are excellent, and the elastic restoring force is excellent, thereby preventing noise.

In addition, the acrylate-based polymer coating layer 140 is excellent in life characteristics does not break due to long-term use.

On the other hand, in the case of forming a coating layer on the fastening structure using a wax as in the prior art, the wax does not reduce the noise caused by the fastening structure between the flooring material and the flooring material because it is not viscous itself, the wax is a fiber board for a long time use There is also a problem in that the formation of the coating is broken due to absorption into the interior.

For example, the first fastening structure 153 is formed to include a protrusion 151 on one side 132 of the flooring material 100, and the second fastening structure 154 is on the other side 131. It may be formed to include a recess 152.

In addition, the flooring material 400 is formed by laminating the shape paper 402 on the fiber plate 401. In this case, the paint layer 470 may be further formed to solve the aesthetic problem in which the bonding surface of the fiber plate 401 and the shape paper 402 is exposed as the connection surface is formed. In this case, after the coating layer 470 is formed, it is preferable to form the acrylate polymer coating layer 440 on the coating layer 470.
