Floor covering using impregnated printing paper and its manufacturing method

The present invention relates to a flooring material using impregnated printing paper and a manufacturing method thereof.

In the flooring which is installed on the floor of the building, used as a floor decoration material;

The surface layer is composed of a UV coating layer and a PET melt sheet layer of the present invention configuration,

In the lower part of the PET melt sheet layer, the impregnation printing layer which is impregnated printing paper impregnated with urethane or acrylic, melamine, urea, phenol resin is provided on the printing paper,

Due to the PU bond impregnated glass fiber layer on the lower part of the impregnated printing layer, the bottom material using the impregnated printing paper and the manufacturing method thereof, consisting of a synthetic resin base layer of the base layers 1 and 2 laminated in the longitudinal and transverse directions, respectively.

In particular, to solve the problem that the veneer decay due to the water resistance degradation due to the moisture absorption of the veneer flooring of the prior art veneer;

In order to solve the problem of moisture absorption of the flooring material of the veneer composition, the waterproofing paint or epoxy resin and urethane resin waterproofing agent were separately applied to both sides of the finished flooring material with a thickness of 3 to 5 mm to solve the waterproofing problem. To solve the problem that the troublesome work takes due to a lot of labor and deterioration, and the failure rate of the flooring material due to poor coating of the waterproofing agent is frequently generated, which makes it difficult to use, thereby improving workability and cost reduction;

The impregnated printed layer is composed of impregnated printed layers impregnated with urethane or acrylic, melamine, urea, and phenolic resin on printed paper on which various patterns including veneer patterns are printed. The present invention relates to a flooring material using impregnated printing paper and a method for producing the same, which have a beautiful effect.

Recently, the flooring material consisting of wood veneer on the floor of the building or the flooring using the veneer, which is composed of synthetic resin layers laminated on the outside of the veneer, to enhance the waterproofness and rigidity of the wood veneer;

In addition, the flooring material having a structure in which a synthetic resin sheet layer is bonded to a sheet of paper or paper is widely used.

As shown in Figure 7, the veneer flooring 200 used as a flooring of the prior art,

Synthetic resin upper and lower layers 201, underlayers 1,2 (203,204), balance layers 205, and glass fiber layers 230, which are a plurality of synthetic resin sheets, which are synthetic resin sheet layers 210, on the upper and lower portions of veneer 220, which are substrates. ) Are laminated to each other, and the first and fourth adhesives 241, 242, 243, and 244, which are multiple adhesives for forming a plurality of adhesive layers, which are adhesives 240, are coated and bonded, respectively.

It consists of 200 product structures.

This is because the synthetic resin sheet layer 210 and the glass fiber layer 230, which are a plurality of synthetic resin sheets 201, 202, 203, 204 and 205, respectively, are stacked on the upper and lower portions of the veneer 220, which is the substrate,

Wear resistance is satisfied by the upper layer 201 having a thickness of 0.6 to 1.0 mm, which is one component of the plurality of synthetic resin sheets,

Dimensional stability properties of the veneer 220, which is the base material, are satisfied by the plurality of synthetic resin sheets, the stop layer 202, the base layers 1, 2, (203, 204) and the glass fiber layer 230,

The finished product veneer flooring 200 is composed of a balance layer 205, which is a synthetic resin sheet for preventing the lifting of the finished product (curling).

In addition, the patent registration No. 10-0884592 by the applicant in the PET melt sheet layer 10, the synthetic resin upper layer layer 20, the adhesive film layer 30, veneer 40, PU bond impregnated glass fiber layer 50, A synthetic resin underlayer 60 composed of underlayers 1,2 and 61 and 62; As the flooring is constructed, wear resistance and dimensional stability of the flooring are reinforced, and the flooring is composed of veneer flooring which is prevented from lifting.

However, the veneer flooring 200 of the prior art as described above;

Due to the deterioration in water resistance due to moisture absorption of the wood veneer, the veneer is broken, there is a problem that the antibacterial deterioration;
