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

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the understanding why the present invention is not intended to be a complete disclosure.

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 intended to distinguish the constituent elements from other constituent elements, and the terms do not limit the nature, order or order of the constituent elements.

FIG. 1 is a cross-sectional view of a waterproof structure according to an embodiment of the present invention, and FIG. 2 is a flowchart of a method of constructing a waterproof structure according to an embodiment of the present invention.

1, the waterproof structure 10 of the present invention is applied to a concrete surface such as a wall or a floor of a building. The waterproof structure 10 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.

The primer layer 11 is formed of a first primer made of an aqueous acrylic emulsion resin. The aqueous acrylic emulsion resin may be prepared by emulsion polymerization of 93 to 98 parts by weight of an ester 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 the primer layer 11 can penetrate the concrete layer 1 by 93% to 98% .

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

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

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

The first waterproofing agent is prepared 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 be. 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 waterproofing agent per 1 m 2 of the primer layer 11.

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

The long fibers are attached to the upper surface of the first waterproof layer 12 immediately after the first waterproofing agent is applied.

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

The sheet layer 13 may be formed by impregnating the long fiber with an impregnation solution.

The long fibers are made of polyester and can be manufactured by a needle punching method. The thickness of the long fibers is preferably from 1.5 mm to 3.0 mm, and the mass per 1 m 2 is preferably from 250 g to 270 g.

Such long fibers are excellent in tensile performance and can absorb impacts such as vibration, thereby effectively preventing microcracks. Also, the long fibers can prevent the heat from moving to the first waterproof layer 12 because the long fibers are good in heat insulation.

The impregnation solution may be prepared by mixing 22 to 28 parts by weight of the first primer, 45 to 55 parts by weight of the first waterproofing agent, 4 to 6 parts by weight of the heat shielding material, and 18 to 22 parts by weight of water.

The impregnating solution not only improves the tensile performance of long fibers, but also minimizes the damage of long fibers due to heat.

The heat shield may be titanium dioxide.

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

The heat barrier material may be a fine vacuum ceramic powder mainly composed of aluminum silicate.

The aluminum nitrate silicate has good chemical resistance and minimizes the deformation of the long fiber and can prevent the heat transfer to the first waterproof layer 12 together with the long fiber due to the low thermal conductivity.

Since the alunium silicate improves the air permeability and can discharge the moisture of the concrete layer 1 to the outside, the sheet layer 13 or the like is corroded by moisture or the moisture expands and the first waterproof layer 12 and the sheet layer 13 can be prevented from being damaged.

The long fiber is formed to have a thickness of 1.5 to 3.0 mm, and 0.8 to 0.9 kg of the impregnation solution can be applied to a length of 1 m 2 of the long fiber.

[ Example  2] Second sheet layer production

A first impregnation solution prepared 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 was impregnated into the first long fiber, Layer.

The first primer may be composed mainly of a first aqueous acrylic emulsion resin emulsion polymerized with 95 parts by weight of an ester acrylate and 4 parts by weight of acrylic acid.

The first waterproofing agent is prepared 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.

The second waterproof layer 14 may be formed by applying the second waterproof agent to the sheet layer 13 in an area of 1 m 2 to 0.6 kg to 0.8 kg. The second waterproofing agent may permeate into the inner space of the sheet layer 13 and a part of the lower layer of the second waterproof layer 14 may be bonded to the sheet layer 13. [
