DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a waterproof sheet (hereinafter referred to as the present sheet S) according to the present invention and a waterproof method using the same will be described in detail with reference to the accompanying drawings.

The present sheet S comprises a PO sheet 3. The POE sheet 3 contacting with the surface to be dried is a key feature of the present invention. The present invention is characterized in that the POE sheet 3 is made of a polyolefin elastomer (polyolefin elastomer) produced by polymerization of a hydrocarbon compound.

The POE sheet (3) mainly composed of a polyolefin elastomer is a polymer compound which is made by polymerization of a chain aliphatic hydrocarbon compound having one double bond and is produced by imparting a non-polar functional group as a basic property of a polyolefin elastomer.

The POE sheet 3 has high affinity with other compounds, has excellent adhesiveness and waterproofness, has a specific gravity lower than that of water, is light in weight, has excellent water resistance and electrical characteristics, and also has such advantages in the present sheet (S) .

In addition, the POE sheet has an excellent adhesion to urethane paint, so it can be directly painted without primer coating.

Here, the POE sheet 3 is preferably adhered to the waterproof construction surface.

FIG. 1 is a chart showing the physical properties of a POE sheet 3, which is a key feature of the present invention, and FIG. 2 is a diagram showing a reaction mechanism of the POE sheet 3. The POE sheet 3, which is a key feature of the present invention, will be described in more detail with reference to FIGS. 1 and 2. FIG.

The POE sheet 3 mainly composed of a polyolefin elastomer has physical properties as shown in FIG. 1. As shown in FIG. 1, the EVA has excellent durability against heat, that is, heat resistance because it has a high melting point. In addition, as shown in the drawing, it is light and has excellent cutting property, and can be conveniently installed, that is, it has excellent workability. It also has the advantage of excellent low-temperature elasticity and less deformation in the production process.

BACKGROUND ART [0002] Conventional technologies relating to waterproof sheets are typically EVA-coated sheets and asphalt sheets. EVA-coated sheets are sheets made of EVA (Ethylene Vinyl Acetate) resin as a main material and generally include releasing paper (nonwoven fabric).

When compared with the present invention, the conventional EVA injection-molded sheets are disadvantageous in that the EVA-coated sheets have low melting point, low heat resistance, are difficult to handle due to softness, In addition, the asphalt sheet is not standardized because the product is standardized, it is difficult to guarantee the freedom of construction, leakage is difficult to find, the repair range is wide, the corner and projecting parts are difficult to install, There are disadvantages.

More specifically. 3, the present sheet S is characterized in that the POE sheet 3 is produced by graft copolymerization of a polyamide (PA 6.6) having a polyolefin and an amine as substituents.

The production process of the POE sheet 3 will be briefly described. When a polyamide (PA 6.6) is bonded to a polyolefin, an amine (H ₂ N), which is a substituent of polyamide, is bonded to form NH and a carboxyl group (COOH) And then graft copolymerization is carried out through a process in which water is released therefrom.

Fig. 3 is a view showing an embodiment relating to a waterproof method (the present method) using the present sheet S. Fig. The method includes a working surface step S1, a waterproof sheet laminating step S2 and a paint applying step S3.

In each step, the work surface S1 is a step of removing foreign substances existing on the work surface together with the work surface flat work, and is a step of smoothing the work surface so that the sheet S can be well stacked on the work surface.

Next, the sheet bonding step S2 is a step of adhering the POE sheet 3 to the upper part of the installation surface, and attaching the POE sheet 3 to the upper part of the waterproofing material 1 as shown in Fig. 3, It is laminated on the construction surface.

Next, the paint application step S3 is a step of applying paint to the upper part of the waterproof sheet. As described above, the paint can be made of urethane paint. Since the POE sheet 3 has excellent adhesion with the urethane paint The waterproof treatment can be performed stably and stably.

Further, the present method comprising the above steps provides a waterproof method having the effect described in the effect of the present sheet (S) by using the waterproof sheet including the POE sheet (3).

Meanwhile, the present sheet (S) may further contain 2 to 3% by weight of pozzolan. Pozzolan is a natural mineral material such as Diatomite, which is responsible for discharging the toxicity of petrochemicals by anion release, deodorization effect and antibacterial action. Natural pozzolanic diatomaceous earth is a soft rock or clay deposited on the bottom of a sea or a lake, and more than 95% of it consists of a silica component and emits a large amount of far infrared rays, and has fine pores. When the pozzolan is less than 2% by weight, the cleaning effect is low, and when it is more than 3% by weight, the binding force is decreased.

And 3 to 4% by weight of wax or paraffin. The wax or paraffin has a melting point of 40 to 60 DEG C and serves to lower the production temperature of the POE sheet, and does not volatilize and does not deteriorate the quality. When the wax or paraffin is added in an amount of less than 3% by weight, the effect of addition is scarcely produced. If the wax or paraffin is added in an amount exceeding 4% by weight, the brittleness of the POE sheet is increased.

The styrene thermoplastic elastomer may also be contained in an amount of 1 to 2% by weight. It has a hard segment of polystyrene block in the short term of the sock and a soft segment structure of polybutadiene in the middle. It has a low viscosity when it is dissolved in a mixed solvent and has high elasticity and low temperature durability. The synthetic zeolite powder dispersed in the particulate state exhibits a function of preventing cracking of the waterproof coating film caused by elapsing time and lifting of the waterproof coating caused by lack of low temperature durability during the winter season. The waterproof coating has the advantage of showing additional functions such as soundproofing and sound absorption

And 2.5 to 3.5% by weight of an amine-based curing agent. If the content of the amine-based curing agent is less than 2.5% by weight, the strength and durability may be lowered and the physical properties may be deteriorated. If the content of the amine-based curing agent is more than 3.5% by weight, the viscosity is increased and the workability is deteriorated.

And 1.5 to 3% by weight of an amorphous polyolefin. This amorphous polyolefin (APO) is a strong adhesive material obtained by adding olefins such as ethylene and propylene, and lowers the thermal conductivity of the POE sheet during the summer season.

Further, it may further contain 0.5 to 0.7% by weight of iron slag. This iron slag is a slag generated when refining steel and scrap iron in an electric furnace to produce steel, which is characterized by preventing plastic deformation of the POE sheet and preventing port hole generation on the surface to be waterproofed. When the content of the iron slag is less than 0.5% by weight, the effect thereof is not high. When the content of the iron slag is more than 0.7% by weight, the increase in the effect is insignificant.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
