Hereinafter, some embodiments of the present invention will be described in detail.

In describing the embodiments of the present invention, when it is determined that a detailed description of a related well-known configuration or a known function interferes with an understanding of an embodiment of the present invention, the detailed description thereof will be omitted.

In addition, in describing the components of the embodiment of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are only for distinguishing the components from other components, and the nature, order or order of the components are not limited by the terms.

1 is a cross-sectional view of a waterproof structure according to an embodiment of the present invention, Figure 2 is a flow chart of the construction method of the waterproof structure according to an embodiment of the present invention.

Referring to FIG. 1, the waterproof structure 10 of the present invention is constructed on a concrete surface such as a wall or a floor of a building, and includes a primer layer 11, a first waterproof layer 12, a sheet layer 13, A second waterproof layer 14, a third waterproof layer 15, a fourth waterproof layer 16, and a top coating layer 17 are included.

The primer layer 11 is formed of a first primer made of an aqueous acrylic emulsion resin. The aqueous acrylic emulsion resin may be made by emulsion polymerization of 93 to 98 parts by weight of acrylate acrylate and 2 to 7 parts by weight of acrylic acid.

The primer layer 11 may be formed by applying 0.28 kg to 0.32 kg of the first primer per 1 m 2 of the concrete layer 1 so that 93% to 98% of the primer layer 11 may penetrate the concrete layer 1. .

Since the primer layer 11 is coated on the uppermost surface of the concrete layer 1 with acrylic acid ester having excellent chemical resistance, moisture resistance, and adhesion, the first waterproof layer 12 and the concrete layer 1 Adhesion performance can be improved.

The first waterproof layer 12 is applied to the upper surface of the primer layer 11.

The first waterproof layer 12 is formed of a first waterproofing agent.

The first waterproofing agent is made by mixing 30 to 40 parts by weight of ethylene vinyl acetate, 40 to 50 parts by weight of the aqueous acrylic emulsion resin, and 15 to 20 parts by weight of polybutyl acrylate. Can lose. The first waterproof layer 12 formed of the first waterproofing agent has an increased adhesion to the primer layer 11.

The first waterproof layer 12 may be formed by applying 0.45 kg to 0.49 kg of the first waterproof agent per 1 m 2 of the primer layer 11.

The sheet layer 13 may be provided on an upper surface of the first waterproof layer 12 and may include long fibers and an impregnation solution.

Here, the long fibers are attached to the top surface of the first waterproof layer 12 immediately after the first waterproofing agent is applied.

Accordingly, the sheet layer 13 may be attached to the first waterproof layer 12.

The sheet layer 13 may be formed by penetration of an impregnating solution into long fibers.

And the long fibers are made of polyester (polyester), can be produced by the needle punching (needle punching) method. In addition, the thickness of the long fiber is 1.5mm to 3.0mm, the mass per 1m 2 is preferably 250g to 270g.

Such long fibers can absorb shocks such as vibrations due to excellent tensile performance, thereby effectively preventing microcracks. In addition, the long fiber is good thermal insulation can prevent the heat transfer to the first waterproof layer (12).

Since titanium oxide absorbs light energy, titanium oxide can prevent heat from being transferred to the first waterproof layer 12 together with the long fibers. Titanium oxide also increases long fiber life by minimizing damage to long fibers.

On the other hand, the heat shield may be a fine vacuum ceramic powder, the main component is aluminum silicate (Alumino Silicate).

The aluminum silicate has good chemical resistance to minimize deformation of the long fibers, and can prevent heat from being transferred to the first waterproof layer 12 together with the long fibers due to the low thermal conductivity.

In addition, since the aluminium silicate may improve moisture permeability to discharge moisture of the concrete layer 1 to the outside, the sheet layer 13 and the like may be corroded by moisture, or the moisture may expand to expand the first waterproof layer ( 12) and the phenomenon that the sheet layer 13 or the like is broken can be prevented.

And the long fiber has a thickness of 1.5mm to 3.0mm, the impregnating solution may be applied 0.8kg to 0.9kg in the long fiber width 1m 2 .

It can be seen that the first sheet layer has improved tensile strength and elongation than the first long fiber.

[ Example  2] second sheet layer fabrication

The first sheet was impregnated with a first impregnating solution made by mixing 25 parts by weight of the first primer, 50 parts by weight of the first waterproofing agent, 5 parts by weight of titanium oxide, and 20 parts by weight of water, to form a second sheet. I made a layer.

Here, the first primer may be made of 95 parts by weight of acrylic acid (esther acrylate) and 4 parts by weight of acrylic acid (acrysion acid) as the main component of the first aqueous acrylic emulsion resin emulsified polymerization.

In addition, the first waterproofing agent is made by mixing 35 parts by weight of ethylene-vinyl acetate, 45 parts by weight of the first aqueous acrylic emulsion resin, and 17 parts by weight of polybutyl acrylate.

[ Experimental Example  2] tensile strength of the second sheet layer Elongation

The tensile strength Elongation 1st long fiber 1476.9 N 67.2% Second sheet layer 1566.8N 76.1%

It can be seen that the tensile strength and the elongation of the second sheet layer are improved than the first long fibers.

[ Experimental Example  3] Determination of the thermal conductivity reduction rate of the first sheet layer and the second sheet layer

Table 3 below shows the reduction rate of the thermal conductivity of the first sheet layer and the second sheet layer when the thermal conductivity of the first long fiber is 1.

Reduction rate of thermal conductivity First sheet layer 0.87 Second sheet layer 0.88

The second waterproof layer 14, the third waterproof layer 15, and the fourth waterproof layer 16 may be formed by applying a second waterproof agent, respectively.

The second waterproofing agent may be made by mixing 52 to 56 parts by weight of ethylene-vinyl acetate, 23 to 27 parts by weight of the aqueous acrylic emulsion resin, and 13 to 17 parts by weight of polybutyl acrylate. Can be.

The second waterproof layer 14 may be formed by applying the second waterproofing agent to 0.6 kg to 0.8 kg in an area of 1 m 2 of the sheet layer 13. As the second waterproof agent penetrates into the interior space of the sheet layer 13, the second waterproof layer 14 may have a portion of the lower layer bonded to the sheet layer 13.

The second waterproof layer 14 is completely combined with the sheet layer 13, thereby preventing lifting or pinhole generation.

The third waterproofing layer may be formed by applying the second waterproofing agent to 0.4 kg to 0.5 kg in an area of 1 m 2 of the second waterproofing layer 14.
