Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1A is a cross-sectional view showing the structure of the water-repellent film to which the technique of the present invention is applied, and accordingly, the water-repellent film 1 of the present invention has an adhesive force on one surface of the blocking means 100 to prevent infiltration of leachate, dry water and ground water. (Adhesion force) and the coating layer 300 having a waterproof function is produced by applying to one surface and the film 140 to prevent damage to the blocking means 100 is installed on the other side.

In the structure of the blocking means 100, a nonwoven fabric 110 is installed on one side and a woven fabric 130 is installed on the opposite side, and the bentonite particles 120 are filled between the nonwoven fabric 110 and the woven fabric 130. It is a structure formed by needle punching.

The film layer 300 is installed on one side of the blocking means 100, that is, the nonwoven fabric 110 or the woven fabric 130, and the opposite surface on which the coating layer 300 is formed. It is a structure made of

On the other hand, the structure of the barrier film 1 of another structure of the present invention, as shown in Figure 1b and 1c of the accompanying drawings, the non-woven fabric 110 is installed on one side and the woven fabric 130 is installed on the opposite side of the non-woven fabric 110 Needle-punched in the state of filling the bentonite particles 120 between the woven fabric 130 and the coating layer is formed on the nonwoven fabric 110 or the surface of the woven fabric 130 of the needle punched blocking means 100 and the coating layer 300 The blocking means 100 formed by attaching the film 140 to the opposite side formed with the protective film 200 to prevent damage to the blocking means 100 and the film 140 is further provided You can also use (1).

The reason of needle punching before attaching the film 140 to the nonwoven fabric 110 or the woven fabric 130 surface is that when the film 140 is attached and needle punched, the film 140 is damaged by a needle and is waterproof. This is due to the loss of functionality.

In this case, the coating layer 300 has an acrylic monomer, an emulsifier, and an initiator such as ethyl hexyl acrylate (EHA), butyl acrylate (Butyl acrylate), and ethyl acrylate monomer (EAM). It is a water-soluble liquid polymer obtained by synthesizing and has a waterproofing property and an adhesive property when dried.

Although the coating layer 300 is formed on one surface of the blocking means 100 and then attached to the structure, the coating layer 300 may be applied to the structure as aqueous.

In the construction method of the barrier film 1 of the present invention having the above structure, as shown in the accompanying drawings, first, a coating film for forming a coating layer 300 by applying a coating liquid having a waterproof function and an adhesive function to a wall is formed. The layer forming process (S200) is performed.

At this time, when the coating liquid is applied to the dry wall without moisture in performing the coating layer forming process (S200), it is difficult to apply the coating liquid because the wall absorbs the moisture of the aqueous coating liquid and cures too quickly. This is because, when the degree of smoothness is lowered and the moisture of the coating liquid to be applied is taken away and cured too quickly, air bubbles (pores) are generated and the adhesive strength is lowered.

Therefore, if the wall surface is dry before performing the coating layer forming process (S200), it is preferable to perform the water supply process (S100) of spraying water so that water remains on the surface of the wall surface.

Meanwhile, a drying process (S300) of drying the coating layer 300 formed by applying the coating liquid is performed. After applying the coating liquid to the wall to form the coating layer 300, if the attachment of the blocking means 100 immediately attached, there is a problem that the adhesive force is not generated and falls. Therefore, in order to attach the blocking means 100, a drying process (S300) of drying the coating layer 300 must be performed for at least 10 minutes.

The nonwoven fabric 110 is installed on one side of the coating layer 300 formed by the coating layer forming process (S200), and the woven fabric 130 is installed on the opposite side thereof, and the bentonite particles are formed between the nonwoven fabric 110 and the woven fabric 130. Needle punching 120 in the filled state and attached to the needle punched blocking means 100, as shown in Figure 1b to Figure 1c non-woven fabric 110 or woven fabric 130 of the blocking means 100 The blocking means 100 formed by attaching the film 140 to the surface may be used.

At this time, one side portion of the adjacent blocking means 100 performs an attachment process (S400) of overlapping attachment as shown in FIGS. 2 to 5. The form of attaching the blocking means 100 may be installed vertically as shown in FIG. 2 or horizontally as shown in FIG. 5.

When the adhesion step (S400) for attaching the blocking means 100, on which the coating layer 300 is formed by the coating layer forming process (S200) to the wall, was tested for viscosity, adhesion performance and water permeability. It was found that the table below.

Test method: Fiber-reinforced cement board + adhesive (film layer) + woven fabric specified in KS F 4934

Coating layer coating amount: 0.33kg / ㎡

The reason of the needle punching is used as a fixing means for fixing the bentonite 120 while preventing the bentonite 120 from being accumulated in one direction. On the other hand, if the blocking means 100 is installed on the wall so as not to overlap, leakage may occur between the adjacent blocking means 100 and the blocking means 100, so that the blocking means 100 are overlapped to prevent this. The overlapped portion is preferably installed overlapping at least 10cm or more.

After the tapering step (S500) of fixing the end of the overlapping portion of the blocking means 100 attached to the wall by the attachment step (S400) with a tape may be finished, after performing the taping step (S500) The blocking film 1 may be constructed in the order of finishing step S600 of further installing a protective sheet 200 to prevent damage to the blocking means 100.

The leachate and dry water are first blocked by the film 140 from the partitioned area to another space. However, after the barrier film 1 is installed on the waterproof wall to block the leachate, dry water, and groundwater from passing through the film 140, the leachate, dry water, and groundwater are moved to the blocking film ( When hitting 1) is blocked by the blocking means (100). On the other hand, the leachate, dry water and groundwater passing through the blocking means 100 are again blocked by the coating layer 300, so that the waterproof efficiency is high.

As shown in FIG. 1B or FIG. 1C, the protection means 200 made of a foam sheet installed on the outer side of the wall surface is primarily blocked by the protection means 200. However, after installing the barrier membrane (1) in the waterproof wall to block the movement of leachate, dry water, groundwater passed through the protection means 200, the leachate, dry water, groundwater is moved to the membrane When hitting (1) it is secondarily blocked by the film 140 attached to the surface of the nonwoven fabric 110 or woven fabric 130, and furthermore the film 140 is installed between the blocking means 100 and the protective means 200 Therefore, the contact area with the protection means 200 is increased to provide a function of causing slip, and the slip phenomenon protects the order film 1.

As shown in FIG. 1B or 1C, the secondary film is blocked by the film 140 attached to one surface of the nonwoven fabric 110 or the woven fabric 130, and the film prevents loss of bentonite 120. Will also have.

Meanwhile, leachate, dry water and ground water passing through the blocking means 100 or the blocking means 100 to which the film 140 is attached are absorbed by the bentonite 120 when the blocking means 100 passes. Bentonite 120 absorbing moisture, such as leachate and dry water (지하 水), groundwater causes water expansion to block leachate, dry water, groundwater. Therefore, if the protection means 200 is further installed, the waterproof efficiency is increased.

In the method for installing the blocking means 100, as shown in the accompanying drawings, Figures 1b and 1c, the woven fabric 130 is installed on the outside from the wall surface and the nonwoven fabric 110 may be installed on the backfill side and also used as a building Alternatively, the woven fabric 130 may be installed inward from the wall surface and the nonwoven fabric 110 may be installed outward depending on the installation place such as a landfill.

On the other hand, when the protective sheet 300 is damaged and deformed by earth pressure and consolidation when the protective sheet 200 is refilled after installation of the protective sheet 200, the film 140 has a frictional force between the protective sheet 300 and the film 140. By increasing the role of preventing the breakage of the film 140, that is, the blocking means 100 is effective to ensure the stability of the product.

Meanwhile, as shown in FIG. 5, when the blocking film 1 is installed in the horizontal direction, the taping process (S500) is performed at the end to block the moisture penetrating from the outside such as the fixing function of the end and rainwater. Can be.

Therefore, the present invention improves the waterproof performance, and the installation method of the blocking means is attached to the installation work is very simple, so the work speed is fast, because the installation of the blocking means attached to the wall to prevent damage to the structure (wall) during installation And the like. In addition, by preventing / preventing the movement of dry water and groundwater toward the wall surface, there is an effect such as having a function of preventing soil contamination and protecting the wall surface.
