Description

{Hybrid waterproofing method using mineral substance}

The present invention relates to an inorganic composite waterproofing method.

Among various waterproofing methods used for waterproofing the roof of a building, the coating waterproofing method is a construction method in which a liquid waterproofing agent is applied on the floor of the roof to form a waterproof coating of a certain thickness. This is because the waterproofing agent is applied in a liquid state, it is suitable for construction of complicated part and it is possible to construct seamlessly. In addition, the interlaminar adhesion between the waterproofing agent and the mortar layer, which is the floor of the roof, is good.

Such a waterproofing agent is a coating waterproofing agent using an aqueous or oily liquid agent applied on the bottom surface to evaporate moisture or solvent, and most of the waterproofing agents other than the epoxy resin are used mainly where cracks are expected because of excellent elongation.

Among various kinds of coating waterproofing agents, the emulsion type coating waterproofing agent is a kind that forms a waterproof layer by applying resin emulsion agent to the bottom surface several times. This is because when cracked, cracks due to self-shrinkage are small, but it is difficult to apply in a place having a large area because the material is weak.

Solvent type waterproofing agent is a waterproofing agent which is made by applying rubber paint made by dissolving natural rubber or synthetic rubber in volatile solvent to the floor a number of times on the floor to make a waterproof layer, and volatile solvent is used as much as flammable solvent.

In addition, the epoxy coating waterproofing agent is excellent in adhesion, and can be integrated on the concrete attachment surface. However, when the structure is cracked, the extensibility is low and the crack site can not be waterproofed.

On the other hand, as a method for waterproofing the roof floor, various methods using a waterproofing sheet are introduced in addition to the above-mentioned waterproofing of the film. Basically, the waterproofing method using a waterproof sheet is a method of forming a waterproof surface by connecting waterproof sheets of a certain width having waterproof ability in the width direction.

Korean Patent Registration No. 10-1116924 (composite waterproofing method using a fiber sheet and a reinforcing sheet) has been introduced as a waterproofing method using a waterproof sheet. The waterproofing method has a structure in which a primer and a waterproofing agent are applied on a slab, a fiber sheet is disposed thereon, and a coalescing agent, a reinforcing sheet, an integrated sheet, and a waterproofing agent are sequentially laminated on the fiber sheet.

The reinforcing sheet is a strip-like member which is adhered along the connecting portion of the mutually adjoining fiber sheets and seals the boundary portion of the fiber sheet. The integrated sheet is a member covering the reinforcing sheet and joining to the fiber sheet.

However, the above-mentioned conventional waterproofing method has the disadvantage that the surface of the completed waterproof layer is not smooth because the reinforcing sheet and the integrated sheet having a certain thickness and width are laminated on the flat fiber sheet.

For example, the thickness of the fiber sheet is larger than the thickness of the other portions. Such a problem does not disappear even if a waterproofing agent is thickly applied on the integrated sheet.

Further, since the fiber sheet, the reinforcing sheet, and the integrated sheet are made of different materials but have different physical widths, the expansion ratio and shrinkage ratio vary with temperature, and the reinforcing sheet and the integrated sheet can be easily separated from the fiber sheet. It goes without saying that the function of the waterproof layer can no longer be performed when the reinforcing sheet and the integrated sheet are peeled off from the fiber sheet.

The present invention has been made in order to solve the above problems, and it is necessary to add a reinforcing sheet or an integrated sheet to a joint portion of a fiber sheet, because an inorganic mixed solution having a thick coating film and a high sealing property is used as an intermediate layer And it is an object of the present invention to provide an inorganic composite waterproofing method in which the construction is simple and the surface of the waterproof layer after the completion of construction can be flattened.

In addition, the present invention is characterized in that since the mixture of naconic fibers and silica sand is contained in the mixed layer forming the middle layer, the physical strength and tensile strength of the middle layer is excellent and the cracks hardly occur. Therefore, the probability of defect occurrence is very low, Another object of the present invention is to provide an inorganic composite waterproofing method having excellent bonding strength of a fiber sheet.

In order to achieve the above object, the inorganic composite waterproofing method of the present invention comprises: a bottom surface pretreatment step of preparing a bottom surface to be waterproofed so as to be suitable for waterproofing; A primer applying step of forming a primer layer by applying a primer to a bottom surface of which preprocessing has been completed; An inorganic mixed single-liquid application step of applying an inorganic mixed solution consisting of an inorganic waterproofing agent, a chemical staple fiber and silica sand on the primer layer formed through the primer application step to form an inorganic mixed one-liquid layer; A fiber sheet laminating step of laminating a fiber sheet having a predetermined width on the surface of the inorganic mixed liquid layer, wherein the thickness of the fiber sheet is arranged so as to face the fiber sheet in the width direction so as not to overlap with each other; An inorganic mixed liquid having an inorganic water repellent agent, a chemical staple fiber and silica sand and having a mixing ratio different from that of the inorganic mixed liquid is applied to the upper part of the laminated fiber sheet to form an inorganic mixed two- An inorganic mixed two-liquid applying step of forming an inorganic mixed liquid; An inorganic mixed two-liquid material applying step of applying again the inorganic mixed liquid to the surface of the inorganic mixed two-liquid layer; And a top layer forming step of applying a top coat to the top of the inorganic mixed two-component layer after completion of the reapplication step.

Further, the method further includes a step of applying a heat-sensitive pigment to coat the heat-sensitive pigment on the surface of the upper layer that has been laminated through the upper layer formation step.

In addition, the chemical staple fiber is a NYCON fiber, and the inorganic mixed solution is a mixed solution composed of 15 to 20 g of niacin fiber and 45 to 50 kg of silica fiber per 18 L of the inorganic waterproofing material do.

In addition, the chemical staple fiber is a niacin fiber, and the inorganic mixed liquid is a mixed solution composed of 15 to 20 g of niacin fiber and 45 to 50 kg of silica fiber per 18 L of the inorganic waterproofing material.

The size of the silica sand may be 100 mesh to 150 mesh.

Since the inorganic composite waterproofing method of the present invention as described above uses an inorganic mixed solution having a thick coating film itself and a high sealing property as a middle layer, it is necessary to add a reinforcing sheet or an integrated sheet to the fiber- And the surface of the waterproof layer after the completion of the construction can be flattened.

In addition, the present invention is characterized in that since the mixture of naconic fibers and silica sand is contained in the mixed layer forming the middle layer, the physical strength and tensile strength of the middle layer is excellent and the cracks hardly occur. Therefore, the probability of defect occurrence is very low, The bonding strength of the fiber sheet is excellent.

1 is a block diagram illustrating an inorganic composite waterproofing method according to an embodiment of the present invention.
2 is a cross-sectional view of the inorganic composite waterproofing layer constructed through the waterproofing method shown in FIG.

Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating an inorganic composite waterproofing method according to an embodiment of the present invention. 2 is a cross-sectional view of the inorganic composite waterproofing layer 11 constructed through the waterproofing method shown in FIG.

As shown in the figure, the inorganic composite waterproofing method according to the present embodiment includes a bottom surface pretreatment step 101, a primer application step 103, an inorganic mixed single solution application step 105, a fiber sheet application step 107, An inorganic mixed two-liquid applying step 109, an inorganic mixed two-liquid reapplication step 110, a top layer forming step 111, and a heat-applying pigment applying step 113.

First, the bottom surface preprocessing step 101 is a process of cleaning the bottom surface of the roof slab (13 in FIG. 2) or the bottom surface of the parking lot to remove the obstacles and the like. For example, it removes sand or soil on the floor completely, and moves the various obstacles that interfere with waterproofing work to another place. In addition, if there is a coating layer floating on the bottom surface, the coating layer should be completely cut out and removed.

If the bottom surface is not properly treated, the waterproof layer to be applied on the floor surface may be easily separated from the floor surface and may need to be repaired.

The subsequent primer applying step 103 is a step of laminating a primer layer 15 having a certain thickness by applying a primer to the bottom surface on which the surface treatment is completed. The primer layer 15 adheres to the bottom surface of the bottom slab 13 and firmly fixes the composite waterproof layer 11 to the bottom surface. It is preferable that the primer is an acrylic resin having air permeability.

If the formation of the primer layer 15 is completed through the primer application step 103, the inorganic mixed single-liquid application step 105 is performed. The inorganic mixed single-liquid applying step 105 is a step of laminating an inorganic mixed one-liquid layer 17 having a certain thickness by coating an inorganic mixed liquid on the primer layer 15.

The inorganic mixed one solution is a mixed solution formed by adding a niacin fiber 29 and a silica sand 31 to the inorganic waterproofing agent 33 at a predetermined ratio.

As the inorganic waterproofing agent (33) itself, any commercially available inorganic coating film waterproofing agent can be used. The inorganic coating film waterproofing agent is a waterproofing agent in which a diluent is not used or a diluent used is water, and is easy to apply, has excellent adhesive strength, and has breathability and elasticity.

The niacon fiber 29 is a hydrophilic high-performance nylon fiber reinforcing material prepared from nylon 6 as a raw material. This is a synthetic short fiber having excellent spreadability without aggregation, and is excellent in resistance against external forces such as compression, tensile, twisting, and warping, and has a crack preventing ability by the same.

It is distributed in the three-dimensional structure inside the inorganic waterproofing agent 33 in the state of being put in the inorganic waterproofing agent 33, and it has various performance such as abrasion resistance, alkali resistance and freeze-thaw resistance as well as impact resistance I will exert.

As a result, the inorganic waterproofing agent 33 is prevented from cracking due to the action of the naconic fiber 29, as well as being prevented from being damaged or weakened by impact or load fatigue, and being damaged by repeated freezing and melting I rarely wear it.

In addition, the silica sand 31 is general sand, and its particle size is in particular 100 mesh to 150 mesh. The surface of the inorganic mixed-liquid layer 17 and the inorganic mixed-liquid layer 21 and 23 to be described later are cut off and the surface area is increased, And the bonding strength with respect to the substrate is improved.

In particular, according to the embodiment, other kinds of materials having physicochemical properties similar to those of silica sand may be made into the mesh size. Yellow soil, ceramics or the like may be manufactured to 100 mesh to 150 mesh and used.

Further, in some cases, the synthetic resin may be pulverized into 100 mesh to 150 mesh to be mixed and used.

The mixing ratio of the inorganic mixed solution is 15 g of the niacin fiber 29 and 45 kg of the silica yarn 31 per 18 L of the inorganic waterproofing agent 33.

If the amount of the naconic fiber (29) is less than the above range, the effect of the naconic fiber can not be sufficiently obtained. If the naconic fiber (29) is used excessively, the total construction cost rises to the performance of the naconic fiber.

Even in the case of the silica sand 31, if the input amount is larger than the predetermined range amount, the construction ratio is increased and the elasticity of the inorganic mixed one-layer is lowered.

The succeeding fiber sheet laminating step 107 is a step of laminating the fiber sheet 19a on the surface of the inorganic mixed monolayer 17 to form the fiber sheet layer 19.

The fibrous sheet 19a is laid on the surface of the inorganic mixed monolayer 17 as a nonwoven fabric wound in a roll form. Particularly, the fiber sheet 19a has a certain width, but does not overlap the end portions in the width direction of the neighboring fiber sheets 19a. That is, the widthwise thickness surface 19b of the fiber sheet 19a is opposed to each other.

If necessary, the bonding force between the fibrous sheets 19a may be doubled by penetrating the inorganic mixed liquid between the thickness planes 19b.

After the fiber sheet laminating step 107 is completed, the inorganic mixed two-liquid applying step 109 is carried out. The inorganic mixed two-liquid coating step 109 is a process of forming an inorganic mixed liquid layer 21 by applying an inorganic mixed liquid to the surface of the fiber sheet layer 19.

The inorganic mixed liquid 2 is a mixed liquid composed of an inorganic waterproofing agent 33 and a mixture of a niacin fiber 29 and a silica sand 31 as shown in FIG. It permeates the upper part for a while.

The inorganic mixed liquid has a mixing ratio different from that of the above inorganic mixed liquid. That is, 15 liters of niacon fiber and 45 kg of silica sand were added per 18 L of the inorganic waterproofing agent 33 and mixed.

On the other hand, the lower surface of the fiber sheet layer 19 is completely covered with the inorganic mixed liquid layer 17 and the inorganic mixed liquid layer 21, and the inorganic sheet- The liquid has been absorbed for some time. The inorganic mixed liquid and the inorganic mixed liquid are permeated into the bottom surface and the top surface of the fiber sheet 19a.

However, the inorganic mixed solution and the inorganic mixed solution do not reach the center of the fiber sheet 19a. This is due to the physical properties of the inorganic mixed liquid and the inorganic mixed liquid.

In any case, the central portion of the fiber sheet layer 19 is in an empty state because the mixed liquid does not penetrate, ensuring air permeability. The hollow state means that there is no material other than the fiber structure constituting the fiber sheet. As described above, since air is permeable, air can be circulated horizontally along the direction of arrow a.

The subsequent inorganic mixed two-liquid reapplication step 110 is a step in which the inorganic mixed two-liquid layer 21 is cured and then the inorganic mixed two-liquid solution is applied again to the surface thereof to form the inorganic mixed two- . The inorganic mixed liquid two layers 21 and 23 are mixed liquids having the same mixing ratio.

When the lamination and curing of the inorganic mixed bipyrate layer 23 is completed, an upper layer forming step 111 is carried out to form a top layer 25 by applying a top coat thereon. The top layer 25 protects the inorganic mixed bipolar layer 23 as a coating layer coated on the inorganic mixed bipolar layer 23.

After the lamination of the upper layer 25 is completed, the step of applying the heat-color pigment 113 is continued. The heat spread pigment application step 113 is a process of applying a heat-sensitive pigment to the surface of the upper layer 25. The heat-sensitive pigment is a paint containing a heat insulating component and a heat insulating component, and reflects and radiates solar heat to block accumulation of heat into the interior of the composite waterproof layer 11. [ The life of the complex waterproof layer 11 can be greatly extended by the role of the heat-sensitive pigment layer 27.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, 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.
