Description

Water proofing structure for waterproofing of shingles and metal roof parts}

The present invention relates to a waterproof structure, and more particularly, to a waterproof structure for waterproofing shingles and metal roofing materials used as a roof finishing material for buildings.

Shingle is the roof finishing material for buildings, and asphalt shingles are mainly used. Asphalt shingles are usually made by saturating asphalt on a base material made of glass fiber or paper mat, and spraying stone powder on the saturated surface. The stone powder protects shingles from ultraviolet rays and provides various functions such as giving a three-dimensional effect or color. Shingles are inexpensive and waterproof. The shingles are light and easy to cut or bend, making construction simple. The shingles are about 1/5 of the weight compared to the roof tiles, so they do not burden the building. In addition, since the material of shingles is light and flexible, it can withstand shocks caused by earthquakes or strong winds if there is no defect in construction. However, the gap between the shingles and the overlapping portion infiltrate moisture, and thus requires a separate waterproofing operation.

In Korean Patent Registration No. 10-1520738, a waterproofing material including mortar is coated on a shingle, and the waterproofing material penetrates at intervals between the shingle and is waterproofed. Since mortar contains cement components, it is strongly combined with waterproofing materials and concrete on the roof. The mortar is combined with the shingle and the roof to harden, thereby increasing the waterproofness at the gap. However, the waterproof material according to the patent is difficult to apply to the actual site. Due to the presence of the above-mentioned mortar, which lacks water resistance, the adhesion with shingles is not sufficient and the waterproof effect is poor. In addition, cracks in the waterproof layer occur due to shrinkage and expansion of shingles caused by seasonal changes. When the waterproof layer is broken, cracks in the upper coating material occur. This phenomenon also occurs in the metal roofing material, which is a roof finishing material.

The problem to be solved by the present invention is to provide a waterproof structure for sufficiently securing the adhesive force and the waterproofing effect with the shingle and waterproofing the shingle and the metal roofing material, which do not crack even when the shingles and metal roofing materials contract and expand.

A waterproof structure for waterproofing shingles and metal roof materials for solving the problems of the present invention is applied to any one of the shingles and metal roof materials, and in the waterproof structure located between the adherend and the waterproof layer, the waterproof structure Includes an impregnated fabric impregnated with a waterproof adhesive layer, the waterproof layer is located on the impregnated fabric, and a gap between the adherends is filled with the waterproof adhesive layer.

In the structure of the present invention, the impregnated fabric may be any one of a nonwoven fabric or felt. The waterproof layer includes mortar and adhesive resin. A filling layer made of the waterproof adhesive layer may be included between the waterproof structure and the adherend. The gap between the adherends can be filled by a filling waterproof layer comprising mortar and adhesive resin.

In a preferred structure of the present invention, the adherend may be laminated on a waterproof sheet layer including a waterproof sheet and an adhesive layer. The adhesive layer is in the form of a sheet, and may be formed of any one layer selected from polyvinyl butyral (PVB; PolyVinylButyral), ethyl butyl acetate (EVA; EthylButylAcetate), and thermoplastic polyurethane (polyurethane), or the layers may be laminated. The waterproof sheet is polyethylene terephthalate (PET), polyvinyl chloride (PVC), polycarbonate (PC), polypropylene terephthalate (PPT), polynaphthalene terephthalate (PEN), polyethylene terephthalate glycerol (PETG), polycyclo Hexylenedimethylene terephthalate (PCTG), cycloolefin polymer (COP), cycloolefin copolymer (COC), dicyclopentadiene polymer (DCPD), cyclopentadiene polymer (CPD), polymethyl methacrylate (PMMA) , Polyimide (PI), polyarylate (PAR), polyethersulfone (PES), polyetherimide (PEI), polyurethane (PU), thermal polyurethane (TPU), silicone resin, fluororesin and modified epoxy resin It may be composed of one or a layer selected from them.

According to the waterproof structure for waterproofing the shingles and metal roofing materials of the present invention, by utilizing the adhesive layer supported on the impregnated fabric, sufficient adhesion and waterproofing effects with the shingles and metal roofing materials are secured, and shrinking and expansion of the shingles and metal roofing materials are also achieved. No cracking occurs. In addition, since the waterproof layer is located on the impregnated fabric, the waterproof layer is kept flat without a step.

FIG. 2 is a cross-sectional view as viewed in a direction perpendicular to FIG. 1.
3 is a cross-sectional view for explaining a second waterproof structure according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments described below may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. The embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art. Meanwhile, in the drawings, the thickness of the films (layers, patterns) and regions may be exaggerated for clarity. Also, when a film (layer, pattern) is said to be on top, top, bottom, or one side of another film (layer, pattern), it may be formed directly on another film (layer, pattern) or may be different between them. A film (layer, pattern) may be interposed.

In the embodiment of the present invention, by utilizing an adhesive layer supported on the impregnated fabric, sufficient adhesion and waterproof effect with shingles and metal roofing materials is secured, and cracks do not occur despite shrinking and expansion of shingles and metal roofing materials, and the waterproofing layer is kept flat. Provide a waterproof structure that can be used. To this end, the waterproof structure including the adhesive layer supported on the impregnated fabric will be described in detail, and the characteristics of the waterproof structure will be described in detail. Here, the shingles are roof finishing materials of buildings, and various types of shingles may be applied, but mainly asphalt shingles are used. In the construction that closes the roof with a shingle, a gap between the shingle occurs and an overlapping portion of the shingle exists. Waterproofing the shingles means waterproofing the crevices and overlaps.

The metal roofing material is a metal tile, a color steel plate, a copper plate, a zinc plate, and the like. For example, a metal tile is a building material used as a roofing material by forming a metal in the form of a tile. Metal tile may be used by adding stone powder or other materials to the shape of a tile formed of metal or metal. Metal tiles are light and durable, easy to construct, and greatly shorten the construction period, reducing construction costs, long life, and low maintenance costs. Metal roofing materials combine traditional tile manufacturing technology with state-of-the-art building technology. For example, various functions are added by coating polymers, fire retardants, rust inhibitors, and natural stone particles on steel sheets with corrosion resistance and heat resistance.

Embodiments of the present invention can be applied to both shingles and metal roofing materials, but for convenience of description, description will be made focusing on shingles.

1 is a cross-sectional view for explaining the first waterproof structure 100 according to an embodiment of the present invention. For convenience of description, some of them have been enlarged. However, the drawings are not expressed in a strict sense, and for convenience of description, there may be components not shown in the drawings.

According to FIG. 1, the first waterproof structure 100 is attached on the shingle 20 positioned on the roof RF. Specifically, a waterproof sheet layer 10, a shingle 20, a first waterproof structure 100 and a coat layer 40 are sequentially stacked on the roof RF. The waterproof sheet layer 10 may use a known method, but it is preferable that the waterproof sheet layer 10 includes an adhesive layer 12 and a waterproof sheet 13. On the other hand, although not shown, the waterproof sheet layer 10 may also extend to the drainage of the roof. In some cases, a primer layer 11 may be included between the roof RF and the adhesive layer 12, and a shingle adhesive layer 14 may be included between the waterproof sheet 13 and the shingle 20. The primer layer 11 is intended to facilitate adhesion of the adhesive layer 12 to the roof (RF), and is composed of a primer resin and various additives.

The adhesive layer 12 is in the form of a sheet, and is made of any one layer selected from polyvinyl butyral (PVB; PolyVinylButyral), ethyl butyl acetate (EVA; EthylButylAcetate), thermoplastic polyurethane, or the like, and the layers are stacked. Can be. In particular, polyvinyl butyral has excellent adhesion, impact strength, flexibility and stability, and particularly has good resistance to ultraviolet rays. Polyvinyl butyral is a more suitable material because it has good thermal stability and low sensitivity to moisture.

The surface of the pressure-sensitive adhesive layer 12 can be enhanced through a plasma or corona treatment or a continuous treatment thereof. Here, the continuous treatment is preferably plasma treatment after corona treatment. In the case of the plasma treatment, plasma methods such as atmospheric plasma, reduced pressure plasma, and corona plasma are used. That is, in order to improve the adhesion of the adhesive layer 12, not only chemically cleaning the surface, but also activating the surface, organic substances on the surface are removed by chemical reaction and physical reaction. The adhesive layer 12 that has undergone plasma treatment uses a high energy of ions or electrons to change the chemical bond in a region within a few μm from the surface. The surface of the adhesive layer 12 is activated chemically or physically so that it can react well with other materials. The plasma-treated adhesive layer 12 undergoes surface modification such as surface cleaning such as removal of fine foreign matter, surface roughness change, and formation of polar functional groups.

In the case of the corona treatment, the adhesive force of the surface of the adhesive layer 12 to be treated is increased by using the corona discharge technique. When the adhesive layer 12 is treated with corona, the charged particles in the corona collide with the surface of the adhesive layer 12, thereby oxidizing the surface. Accordingly, the surface energy of the sheet is increased by a polar group generated by surface oxidation, for example, C=O, C-O-H, COOH, -COO-, -CO-, and thus the affinity with the waterproof sheet 13 is enhanced to increase adhesion. In addition, crosslinking structures between polymer molecules may be formed in addition to the above chemical polar groups by corona treatment to improve adhesion. Corona surface treatment is usually produced by placing an adhesive layer 12 between both electrodes where corona discharge is made, and supplying constant power to both electrodes to cause corona discharge.

The adhesive layer 12 of the present invention is not a solidified polymer material having a sticky property. In addition, it always has a fluid gel or semi-solid viscosity. The adhesive layer 12 can be adhered to the surface of the adherend even at a pressure applied manually by an operator. The adhesive layer 12 does not solidify and does not leak substances such as oligomers, so that the adhesion between the waterproof sheets 13 can be maintained for a long time. In addition, it can be easily combined by hand. Since the adhesive layer 12 has viscoelasticity in a gel state, even if deformation occurs due to contraction and expansion of the shingle 20, the adhesive layer 12 absorbs the deformation, so that the first waterproof structure 100 and the coat layer ( Do not crack 40).

The waterproof sheet 13 is polyethylene terephthalate (PET), polyvinyl chloride (PVC), polycarbonate (PC), polypropylene terephthalate (PPT), polynaphthalene terephthalate (PEN), polyethylene terephthalate glycerol (PETG), Polycyclohexylenedimethylene terephthalate (PCTG), cycloolefin polymer (COP), cycloolefin copolymer (COC), dicyclopentadiene polymer (DCPD), cyclopentadiene polymer (CPD), polymethyl methacrylate ( PMMA), polyimide (PI), polyarylate (PAR), polyethersulfone (PES), polyetherimide (PEI), polyurethane (PU), thermal polyurethane (TPU), silicone resin, fluororesin and modified It consists of one type selected from epoxy resins or a layer in which they are laminated.

The waterproof sheet 13 is in the form of a sheet and has a waterproof function. In the conventional coating film waterproofing method, it takes a relatively long time to harden the waterproofing layer by applying the liquid-type waterproofing material several times. In addition, the waterproof layer is not formed with a uniform thickness, and is formed relatively thin, thereby reducing the waterproof ability, and the swelling phenomenon occurs according to water vapor pressure. However, the waterproof sheet 13 is constructed by attaching to the adherend by heat fusion or adhesive, and the product is standardized, so that the thickness of the waterproof sheet 13 is uniformly formed and construction is rapid. When the product is standardized, it has a thickness sufficient for waterproofing by the waterproof sheet 13. However, the embodiment of the present invention utilizes the adhesive layer 12 instead of the adhesive.

On the other hand, in the process of attaching the waterproof sheet 13 to the roof (RF), the bonding between the waterproof sheets 13 is usually bonded after the waterproof sheets 13 are overlapped. Conventionally, after the waterproof sheet 13 was superimposed, thermal welding or adhesive was used. However, in the case of heat fusion, oligomers, etc., flow out from the inside of the waterproof sheet 13 in the process of applying heat, and heat fusion is not properly performed. In particular, this phenomenon is serious in the case of polyvinyl chloride (PVC) mainly used as the waterproof sheet 13. When bonding with an adhesive, the adhesive solidifies physically and chemically. The solidified adhesive is denatured over time, resulting in poor adhesion or cracking of the adhesive layer due to external impact.

The shingle 20 is laminated on the waterproof sheet 13. The shingle 20 is a roof finishing material of a building, and various types of shingles may be applied, but asphalt shingles are mainly used. The asphalt shingles are usually made by saturating asphalt on a base material made of glass fiber or paper mat, and spraying stone powder on the saturated surface. The stone powder protects the shingle 20 from ultraviolet rays, and performs various functions such as giving a three-dimensional effect or color. The shingle 20 is inexpensive and waterproof. The shingle 20 is light and can be easily cut or bent, so construction is convenient. The shingles 20 are about 1/5 of the weight compared to the roof tiles, so they do not burden the building. In addition, since the material of the shingle 20 is light and flexible, it sufficiently withstands impacts caused by earthquakes or strong winds if there is no defect in construction. The shingles 20 applied to the embodiments of the present invention may be applied to other forms of shingles in addition to the shingles presented above within the scope of the present invention.

When the shingle 20 is placed in the same direction as in FIG. 1, a gap G occurs, and when it is placed in a direction perpendicular to the direction in FIG. 1, an overlapping portion a is generated. The overlapping portion (a) will be described in detail in FIG. 2. That is, the process of waterproofing the gap G will be described in FIG. 1, and the process of waterproofing the overlapped portion (a) will be described in FIG. 2.

The first waterproof structure 100 includes an impregnated fabric 30, a waterproof adhesive layer 31 and a waterproof layer 32. The impregnated fabric 30 is a fabric in which the waterproof adhesive layer 31 is impregnated. One example of the impregnated fabric 30 is a mesh structure that facilitates impregnation or penetration of the waterproof adhesive layer 31, and also serves as a buffer protecting the shingle 20. Another example of the impregnated fabric 30 is to form a felt by arranging in a parallel or negative direction and bonding with an adhesive or the like, without going through the woven process of the fibers. That is, the impregnated fabric 30 is a nonwoven fabric, felt, or the like. As the material of the impregnated fabric 30, synthetic resins such as polyolefin and polyester are mainly used, and the impregnated fabric 30 of the present invention can be selected and used as a material having a strong adhesive strength with the waterproof adhesive layer 31.

The waterproof adhesive layer 31 is impregnated into the impregnated fabric 30. The waterproof adhesive layer 31 may be any one of acrylic, vinyl acetate (EVA), vinyl acetate, polyvinyl acetate, and epoxy having excellent waterproof properties, or a resin in which they are suitably mixed. The waterproof adhesive layer 31 is filled in the gap G between the shingles 20. When the waterproof adhesive layer 31 is filled in the gap G and is adhered to either the waterproof sheet 13 or the shingle adhesive layer 14, the gap G is sufficiently waterproofed. Since the conventional waterproofing material contains mortar that lacks water resistance, the adhesive strength with the waterproof sheet 13 or the shingle adhesive layer 14 is insufficient. If this happens, the gap G is insufficiently waterproof. However, in the embodiment of the present invention, since the gap G is filled with the waterproof adhesive layer 31, and is adhered to the waterproof sheet 13 or the shingle adhesive layer 14, sufficient waterproofing is ensured.

The waterproof layer 32 is a layer containing mortar and adhesive resin as in Korean Patent Registration No. 10-1520738. The waterproof layer 32 is combined with the impregnated fabric 30 impregnated with the waterproof adhesive layer 31. The impregnated fabric 30 is sufficient to accommodate the shrinkage and expansion without breaking even when the shingles 20 contract and expand. That is, the impregnated fabric 30 gradually accommodates the shrinkage and expansion so that the waterproof layer 32 does not break even when the shrinkage and expansion occur. Since the waterproof layer 32 is supported by the impregnated fabric 30, the crack of the waterproof layer 32 due to contraction and expansion of the shingle 20 is blocked. If the crack of the waterproof layer 32 does not occur, the crack of the upper coating material 40 is blocked. Further, since the impregnated fabric 30 supports the waterproof layer 32 with constant rigidity, the waterproof layer 32 may have a flat shape.

On the waterproof layer 32, at least one coat layer 40 is laminated. In the drawing, the coat layer 40 of two layers is represented, but more layers may be formed in some cases. Mortar is not included in the coat layer 40. The coat layer 40 serves to supplement the waterproofing of the waterproofing layer 32 while protecting the waterproofing layer 32. The first waterproof structure 100 and the coat material 40 do not contain mortar, and the waterproof layer 32 includes mortar.

FIG. 2 is a cross-sectional view as viewed in a direction perpendicular to FIG. 1. Here, as described in FIG. 1, except that the overlapping portion (a) is included.

According to FIG. 2, the overlapping portion (a) occurs because the shingles 20 overlap each other in the process of closing the roof RF with the shingles 20. Although not shown in the drawings, the overlapping portion (a) can be joined by adhesion or the like. If there is an overlapping portion (a), an empty space is generated between the shingle 20 and the waterproof sheet layer 10 and between the impregnated fabric 30 impregnated with the waterproof adhesive layer 31. The empty space may be filled with first and second filling layers 15 and 33, respectively. The first filling layer 15 may be filled between the shingle 20 and the waterproof sheet layer 10 to fill a material that can prevent the shingle 20 from being damaged, such as an adhesive. The second filling layer 33 is the second filling layer 33 as a waterproof adhesive layer 31 between the impregnating fabric 30 and the shingles 20 for the flattening of the waterproof layer 32 by the impregnating fabric 30. Can form.

A part of the first waterproofing structure 100 is located on the second filling layer 33, and partly on the shingle 20. The impregnated fabric 30 is sufficient to accommodate the shrinkage and expansion without breaking even when the shingles 20 contract and expand. That is, the impregnated fabric 30 gradually accommodates the shrinkage and expansion so that the waterproof layer 32 does not break even when the shrinkage and expansion occur. Since the waterproof layer 32 is supported by the impregnated fabric 30, the crack of the waterproof layer 32 due to contraction and expansion of the shingle 20 is blocked. If the crack of the waterproof layer 32 does not occur, the crack of the upper coating material 40 is blocked. Further, since the impregnated fabric 30 supports the waterproof layer 32 with constant rigidity, the waterproof layer 32 may have a flat shape.

3 is a cross-sectional view for explaining the second waterproof structure 200 according to an embodiment of the present invention. At this time, the second waterproof structure 200 is the same as the first waterproof structure 100, except for including the filling waterproof layer 34 in the gap G. Accordingly, detailed description of the same reference numerals will be omitted.

According to FIG. 3, the second waterproof structure 200 includes a filling waterproof layer 34 including mortar. Preferably, the filling and waterproofing layer 34 is made of the same material as the waterproofing layer 32. Specifically, the filling and waterproofing layer 34 is a mixture of ceramic powder, pigment, adhesive resin, mortar and water. The ceramic powder is, for example, pulverized at least one selected from pulverous rocks, shellfish, diatomaceous earth, white earth, ocher, and stone powder. Typically, 150 to 200 mesh (mesh) is used for the pole. Various types of pigments are available, for example, sugar (titanium dioxide), casein, and whistle. The adhesive resin includes at least an ethylene-vinyl-acetate copolymer EVA, silicone resin, latex and acryl emulsion resin. Mortar is a mixture of cement and sand with water, and the water is one that is contained in the mortar.

The mortar of the filling and waterproofing layer 34 has a good bonding strength with the stone roof of the shingle 20 and a roof made of concrete. The mortar lowers the fluidity of the filling and waterproofing layer 34, so that the filling and waterproofing layer 34 does not flow down and is densely filled at a shingle interval. If the mortar is tightly filled and hardened in the gap between the shingles 20, it is possible to more reliably prevent water from penetrating the gap G between the shingles 20. The filling and waterproofing layer 34 preferably has an adhesive resin: mortar: water in a weight ratio of 1.5 to 2.5: 8 to 12: 4 to 6. If the weight ratio of mortar is less than 8, the bonding strength of the filling and waterproofing layer 34 due to the mortar is lowered. If the weight ratio is greater than 12, the amount of the adhesive resin becomes small, so that the waterproofness of the filled waterproof layer 34 is poor.

On the other hand, the filling waterproof layer 34, in order to increase the water resistance and adhesion, 1 to 10% by weight of butyl acrylate resin, 0.1 to 10% by weight of phthalic acid ester emulsion, 0.1 to 5% by weight of epoxy emulsion or phenol emulsion, and A second coat material containing at least two kinds of 0.1 to 10% by weight of polyoxyethylene octiphenyl ether emulsion can be used. The butyl acrylate resin is a colorless, highly volatile raw material and has a property of quickly forming a polymerized polymer. It has a strong permeability and plays an important role in enhancing adhesion. The butyl acrylate resin is preferably contained in 1 to 10% by weight relative to the second coat material. If the content of the butyl acrylate resin is less than 1% by weight, it is difficult to expect an effect of improving the adhesion, and when it exceeds 10% by weight, the adhesion is improved, but a material separation phenomenon is likely to occur.

Since the filling and waterproofing layer 34 includes mortar, the filling and waterproofing layer 34 is inferior in waterproofness to the first waterproofing structure 100. However, since the first waterproof structure 100 is present on the filling and waterproofing layer 34, the insufficient waterproofness in the filling and waterproofing layer 34 is supplemented with the first waterproofing structure 100. That is, the filling and waterproofing layer 34 increases the bonding force with the shingle 20, and the first waterproofing structure 100 takes charge of waterproofing. In this way, the first waterproof structure 100 including the filled waterproof layer 34 is referred to as a second waterproof structure 200.

Above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications may be made by those skilled in the art within the scope of the technical spirit of the present invention. It is possible. For example, the embodiment of the present invention is also applied to a metal roof material, the shingle adhesive layer 14 may be replaced with a metal roof material adhesive layer, and the shingle 20 may be replaced with a metal roof material.
