Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a waterproofing material filling a space between shingles,

The present invention relates to a waterproofing material and a waterproofing method. More particularly, the present invention relates to a waterproofing material to fill a gap between shingles used as a roof finishing material of a building, and a method of waterproofing a shingle using the waterproofing material.

Shingle is the roof finishing material of the building, mainly asphalt shingle. 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 has various functions such as protecting the shingle from ultraviolet rays, giving a three-dimensional feeling and a color. Shingle is cheap and waterproof. Shingle is lightweight and easy to cut and bend, making construction easy. The shingle is about 1/5 of the weight of the tile, so it does not exert a load on the building. In addition, the material of the shingle is light and flexible, so it can withstand the impact caused by earthquake or strong winds if it does not defy construction. However, since the gap between the shingles is in a depressed state, water penetration is apt to occur, and therefore, separate waterproofing work is required.

Conventionally, a waterproofing material and a waterproofing method for applying the gap between the exposed surface of the shingles and the shingles at the same time have been used. Patent No. 10-0896239 discloses a waterproof material composed of EVA, acrylic resin, vinyl acetate, and polyvinyl acetate. However, the waterproofing material is difficult to be waterproofed in the interval between the shingles, which may be a factor of weak bonding force between the waterproofing material and the shingles. The conventional waterproofing material can not prevent slippage that occurs during construction due to its own lubricating properties. This can cause an accident that the operator slips due to slippery waterproofing during construction.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a waterproofing material and a shingle waterproofing method by filling a gap between shingles to prevent water from penetrating through the gap and filling a space between shingles, .

A waterproofing material for filling the gap between shingles to solve the problems of the present invention includes a ceramic powder, a pigment, a first coating material including an adhesive resin, a mortar dispersed with the first coating material, Lt; / RTI > At this time, the first coat material: the mortar: the water may be mixed in a weight ratio of 1.5 to 2.5: 8 to 12: 4 to 6.

In the waterproofing material of the present invention, the waterproofing material may comprise 1 to 10% by weight of a butyl acrylate resin, 0.1 to 10% by weight of a phthalate ester emulsion, 0.1 to 5% by weight of an epoxy emulsion or a phenol emulsion, And 0.1 to 10% by weight of a phenyl ether emulsion. At this time, the second coat material: the mortar: the water may be mixed at a weight ratio of 1.5 to 2.5: 8 to 12: 4 to 6.

In order to solve the above-mentioned problems, a shingle waterproofing method using a waterproofing material filling a space between shingles first attaches a shingle to a roof. Then, a first waterproofing material mixed with a ceramic powder, a pigment, a first coat material made of an adhesive resin, mortar and water is applied to the surface of the shingle and the interval between the shingles. The first waterproofing material is dried. The first coating material is applied on the dried first waterproofing material a plurality of times. At this time, the first coat material: the mortar: the water may be mixed in a weight ratio of 1.5 to 2.5: 8 to 12: 4 to 6.

In the waterproofing method of the present invention, the waterproofing of the shingle is preferably performed by adding 1 to 10% by weight of a butyl acrylate resin, 0.1 to 10% by weight of a phthalate ester emulsion, 0.1 to 5% by weight of an epoxy emulsion or a phenol emulsion, 0.1 to 10% by weight of oxyethylene octylphenyl ether emulsion, and a second coating material containing an oxyethylene octiphenyl ether emulsion of 0.1 to 10% by weight.

According to the waterproofing material and the shingle waterproofing method for filling the gap between the shingles of the present invention, the adhesion force between the shingle and the roof can be increased by using a waterproof material containing mortar. The waterproofing material of the present invention including the mortar can completely fill the gap between the shingles to prevent water from penetrating the gap. Further, the roughness provided by the mortar can prevent the operator from sliding during the waterproofing work. Further, waterproof property and adhesion can be further improved by mixing butyl acrylate resin, phthalic acid ester emulsion, epoxy emulsion or phenol emulsion and polyoxyethylene octiphenyl ether emulsion with waterproof material.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments described below can be modified into 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 enable those skilled in the art to more fully understand the present invention.

The embodiment of the present invention proposes a waterproofing material and a waterproofing method which can prevent the penetration of water at the interval by completely filling the gap between the shingles by using the waterproof material containing mortar and prevent the slipping during the construction. To this end, a waterproofing material excellent in waterproofing property and capable of preventing slippage in a shingling operation will be described in detail. Particularly, a method of increasing the bonding force between the shingles and the roof in the interval between the shingles and waterproofing the space between the shingles will be described in detail. The process of waterproofing the shingle using the waterproofing material of the present invention will be described in detail. Here, the shingles are roof finishing materials of buildings, and various types of shingles can be applied, but mainly asphalt shingles are 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 has various functions such as protecting the shingle from ultraviolet rays, giving a three-dimensional feeling and a color. Shingle is cheap and waterproof. Shingle is lightweight and easy to cut and bend, making construction easy. The shingle is about 1/5 of the weight of the tile, so it does not exert a load on the building. In addition, the material of the shingle is light and flexible, so it can withstand the impact caused by earthquake or strong winds if it does not defy construction. The shingles applied to the embodiments of the present invention may be applied to other types of shingles in addition to the shingles described above within the scope of the present invention.

<Waterproof material>

The first waterproofing material of the embodiment of the present invention is a mixture of ceramic powder, pigment, adhesive resin, mortar and water. The ceramic powder is obtained by crushing at least one selected from, for example, elvan, clam, diatomaceous earth, clay, loess, and abrasive. Typically, the sieve uses 150 mesh to 200 mesh. There are various kinds of pigments available, for example, peroxide (titanium dioxide), casein, hog and the like. The adhesive resin includes at least an ethylene-vinyl-acetate copolymer (EVA), a silicone resin, a latex, and an acrylic emulsion resin. The mortar is obtained by kneading cement and sand with water, and the water is excluded from the mortar.

In the first waterproofing material according to the embodiment of the present invention, a mixture of ceramic powder, pigment and adhesive resin is also referred to as a first coat. The first coat material is one example of what is conventionally used in shingle work. Such a first coating material may contain other resin compositions within the scope of the present invention. That is, the first waterproofing material of the present invention is a mixture of the first coat material, the mott tar, and water. Mortar has good bonding strength with shingle stone powder and concrete roof. The mortar lowers the fluidity of the first waterproofing material, and the first waterproofing material is tightly filled in the shingling interval without flowing down. When the mortar is tightly filled in the gap between the shingles and hardened, it is possible to more reliably prevent water from penetrating into the gap between the shingles. The mortar roughens the surface of the first waterproofing material. When the first waterproofing material is applied to the surface of the shingle, the surface of the shingle is roughened so that the worker can be prevented from sliding.

The first coating material: mortar: water is preferably 1.5 to 2.5: 8 to 12: 4 to 6 in terms of the weight ratio of the first waterproofing material. When the weight ratio of the mortar is less than 8, the binding force of the first waterproof material due to the mottle tar is lowered. If the weight ratio is more than 12, the amount of the first coating material becomes small, and the waterproof property of the first waterproofing material is deteriorated. However, the first waterproofing material requires a certain drying time in order for the mortar to cure. The drying time may be 7 to 15 days. This drying time can be determined by the depth, width, etc. of the interval between shingles.

In the meantime, in order to improve the waterproof property and the adhesive strength, it is preferable that 1 to 10% by weight of a butyl acrylate resin, 0.1 to 10% by weight of a phthalic acid ester emulsion, 0.1 to 5% by weight of an epoxy emulsion or a phenol emulsion, And 0.1 to 10% by weight of a polyoxyethylene octiphenyl ether emulsion can be used as the second coating material. The butyl acrylate resin has a property of rapidly forming a polymerized polymer as a colorless and volatile strong raw material. It is highly permeable and plays an important role in strengthening the adhesion force. The butyl acrylate resin is preferably contained in an amount of 1 to 10% by weight with respect to the second coating material. When the content of the butylacrylate resin is less than 1 wt%, it is difficult to expect the effect of improving the adhesion. If the content of the butyl acrylate resin exceeds 10 wt%, the adhesion is improved but the material separation phenomenon tends to occur.

The phthalic acid ester improves plasticity and prevents material separation. The phthalate ester is preferably contained in an amount of 0.1 to 10% by weight based on the second coating material. If the content of the phthalic acid ester is less than 0.1% by weight, the effect of improving the plasticity and preventing the separation of materials may be deteriorated. If the content of the phthalic acid ester exceeds 10% by weight, the mechanical strength may be decreased. The epoxy emulsion or phenol emulsion improves adhesion strength and durability. The emulsion is preferably contained in an amount of 0.1 to 5% by weight based on the second coating material. If the content of the epoxy emulsion is less than 0.1% by weight, the effect of improving the adhesive strength and durability may be insufficient. If the content of the epoxy emulsion is more than 5% by weight, the adhesive strength and durability are improved but brittleness is likely to occur.

The polyoxyethylene octiphenyl ether emulsion improves the penetration and diffusion rate and improves dispersion and storage stability. The polyoxyethylene octiphenyl ether is preferably contained in an amount of 0.1 to 10% by weight based on the second coating material. When the content of the polyoxyethylene octiphenyl ether is less than 0.1% by weight, the workability is improved but the dispersibility and storage stability are deteriorated. When the content is more than 10% by weight, the dispersibility and the penetration diffusion rate are increased but the pot life is shortened .

The second waterproofing material is preferably in a weight ratio of 1.5 to 2.5: 8 to 12: 4 to 6 in terms of the second coat material: mortar: water. If the weight ratio of the mortar is less than 8, the binding force of the second waterproof material due to the mottle tar is lowered. If the weight ratio is larger than 12, the amount of the second coating material becomes small, and the waterproof property of the second waterproofing material becomes poor. However, it takes a certain drying time for the mortar to cure. The drying time may be 7 to 15 days. This drying time can be determined by the depth, width, etc. of the interval between shingles. The first and second waterproofing materials of the present invention can be freely selected in consideration of the characteristics of the shingling operation.

<Waterproofing>

1 is a flowchart illustrating a shingle waterproofing method according to an embodiment of the present invention. 2A to 2C are cross-sectional views illustrating a shingle waterproofing method according to an embodiment of the present invention. In this case, the shingles, the waterproofing material and the coating material will be described with reference to the above description.

Referring to FIGS. 1 and 2A, a shingle 14 is attached to a nonwoven fabric 12 on a roof 10 and a nonwoven fabric 12 is covered (S10). An adhesive material may be used in the process of attaching the nonwoven fabric 12 and the shingle 14. The nonwoven fabric 12 alleviates the external impact on the shingle 14 and allows the adhesive material to easily adhere to the shingle 14 and the roof 10. In the process of attaching the shingles 14, a slight gap G is generated between the shingles 14 due to physical limitations. Water penetration into the gap G damages the nonwoven fabric 12 and weakens the adhesive force of the adhesive material. Damage to the nonwoven fabric and weakening of the adhesion force separate the shingle 14 and the roof 10. Further, since the surface S of the shingle 14 is exposed to the outside, erosion may occur with time. Accordingly, a waterproof and protective process for covering the gap G between the shingles 14 and the shingles is required.

Referring to FIGS. 1 and 2B, the gap S between the shingles is filled with the first or second waterproofing material 16 (S12). A part of the first or second waterproofing material 16 penetrating through the gap G between the shingles passes through the nonwoven fabric 12 and contacts the roof 10. [ The first and second waterproofing materials 16 include mortar. Since the mortar has a cement component, it is strongly bonded to the stone powder of the shingle 14 and the concrete of the roof 10 and the like. Accordingly, the mortar hardens in combination with the shingle 14 and the roof 10, so that the waterproof property at the gap G can be enhanced. By the mortar, the first or second waterproofing material 16 according to the embodiment of the present invention is strongly bonded to the shingle 14 as compared with the conventional waterproofing material.

Also, since the first or second waterproofing material 16 includes the above-described first and second coating materials (18 in FIG. 2C), it is possible to prevent water from penetrating into the shingles 14. Since the first or second coating material 18 is adhered to the shingle 14 and the roof 10 together with the mortar, water resistance can be enhanced. The mortar in the first or second waterproofing material (16) of the present invention roughens the surface of the coated film. If the surface of the coated film is rough, it is possible to prevent the operator from sliding on the coated film. On the other hand, the first or second waterproofing material 16 may be differently applied depending on the shape of the roof 10. If the roof 10 is inclined, the first or second waterproofing material 16 may flow down from the ridge portion. When the roof 10 is flat, it can be coated with a roller or the like.

Referring to FIGS. 1 and 2C, the first or second waterproofing material 16 requires a drying time to be adhered to the shingle 14 and the roof 10 due to the characteristics of the mortar. Normally, the drying time is sufficient for about 7 days, but it can be dried for 10 days or even 15 days for more reliable curing (S14). When the drying is completed, the first or second coating material 18 is coated on the first or second waterproofing material 16 (S16). The first or second coating material 18 does not contain mortar. That is, the first or second coating material 18 is primarily waterproof. The first or second coating material 18 is preferably applied a plurality of times (for example, twice). Even if the first or second coating material 18 is applied, there is a surface irregularity due to the mortar of the first or second waterproof material 16 in the lower part, so that the slipping phenomenon can be prevented.

On the other hand, when the work of covering the roof 10 with the shingle 14 is completed, the end of the roof 10 is finished. Thus, the finishing process is called a flushing operation. In the flushing operation, the first or second waterproofing material 16 is applied, and the nonwoven fabric is tightly adhered while wrapping the end portion thereof. Preferably, the nonwoven fabric is adhered in a "C" shape. The nonwoven fabric is adhered and fixed to the shingle 14 by the first or second waterproofing material 16. Then, the first or second coating material 18 is applied to the attached nonwoven fabric to complete the flashing operation. Further, the ventilator portion can form a coating film with the first or second coating material 18 without using the first or second waterproofing material 16. [ In other words, the portion to which the first or second waterproofing material 16 according to the embodiment of the present invention is applied is a portion where the shingles 14 are present.

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 many variations and modifications may be made without departing from the spirit and scope of the invention. It is possible.
