As described above, the present sheet has the advantage of adding high strength and heat resistance, which are characteristics of the ceramic material itself, by having the ceramic particles 22 on the nonwoven member 21 provided on the waterproof adhesive layer 1 .

Since the surface of this sheet is provided with a ceramic material in the form of particles (eg, granules) on the surface, the surface of the sheet is easy to bend and the sheet can be attached to a construction surface having various shapes. have.

In addition, since the ceramic material is provided in the form of particles, this sheet can be stored in the form of a roll (roll shingle), which also has the advantage of easy storage and transport.

As described above, in the prior art, asphalt used to be attached to the construction surface as a waterproofing material, but the appearance was not excellent because the color was black. This sheet is provided with a finishing layer (2) on the waterproof adhesive layer (1) can improve the aesthetics of the sheet.

Referring to FIG. 1 , at least a portion of the plurality of ceramic particles 22 may be colored by commonly used dyes to form a pattern when viewed in a plan view.

4 is a schematic flowchart for explaining a method of constructing a roof covering material according to an embodiment of the present invention.

Meanwhile, a description will be given of a roof finishing material construction method (hereinafter referred to as 'this method') according to an embodiment of the present invention. However, this method relates to the construction method of the roof finishing material using the above-mentioned sheet, and since it includes the same or corresponding technical characteristics as the above-described sheet, the same reference numerals are used for the same or similar configuration as the above salpin configuration. and overlapping descriptions will be simplified or omitted.

1 to 4 , the method includes a background treatment step (S1), a primer application step (S2), a roof finishing material attachment step (S3), and a post-treatment step (S4).

This method is preferably carried out in a state where the air temperature is 5° C. or higher and there is no rain or snow.

The background treatment step (S1) includes a step (S11) of removing foreign substances from the construction surface, and a step (S12) of filling the defective part.

The background treatment step (S1) is a step for improving the adhesion and airtightness of the waterproof adhesive layer 1 and the construction surface in the step (S3) to be described later.

The process (S11) may be exemplarily performed through a brush or the like. Step (S11) is a step of removing foreign substances such as dust, oil, and moisture. (S11) It is preferable that the moisture content of the construction surface after the process is 8% or less.

The step (S12) may be a process of filling the defective parts (cracks, grooves, damaged parts, etc.) with sealant or concrete or reinforcement seal, cement mortar, and the like.

The background treatment step (S1) may include a step (S13) of removing the protruding portion of the construction surface.

In addition, the background treatment step (S1) may include a process of making a 30-50mm R surface or a reduced surface with a seal for reinforcement or a cement mortar or triangular preservative wood at the corners and corners of the construction surface.

The primer application step (S2) is a step of applying an asphalt primer (eg, city asphalt primer (KSM 2270)).

The primer application step (S2) may be performed using an application device such as a brush or roller.

Although the amount of asphalt primer application varies depending on the structure and condition of the road surface, it is preferable that 0.4L per square meter is applied uniformly.

It is desirable to prevent contact with water or leaving it for a long time after the asphalt primer is applied.

The roof finishing material attaching step (S3) is a step of attaching the waterproof adhesive layer 1 provided under the finishing layer 2 on the construction surface.

The construction surface was referred to as the roof of the building as described above, and the roof may include a ridge, eaves, etc. in terms of structure, and a flashing (including flashing, exemplarily valley freshening, ridge freshening, eaves freshening, etc.) may include That is, in the roof finishing material attaching step (S3), the sheet can be attached to a roof made of a ridge, eaves, flashing, and the like.

As described above, the release film 3 can be attached to the lower portion of the waterproof adhesive layer 1, and in the step (S3), the release film 3 is first removed and the waterproof adhesive layer 1 is attached to the construction surface.

When the waterproof adhesive layer (1) is attached to the construction surface, the waterproof adhesive layer (1) may be heated with a torch or the like in order to improve adhesion.

In the roof finishing material attachment step (S3), the waterproof adhesive layer 1 may be attached from the eaves to the ridge. When constructing the waterproof adhesive layer (1), the release film (3) is attached while peeling off little by little, and it is preferable to suppress the inflow of air between the waterproof adhesive layer (1) and the construction surface.

The neighboring main sheets except for the release film 3 to be installed on the roof may be attached to the construction surface so that their ends overlap each other (overlap).

This method is a process (S41) of injecting a sealant (eg, an exterior water-based sealant) between the neighboring roof finishing materials (F) (this sheet after the step (S3) is in a state in which the release film 3 is removed) (S41) , and a post-processing step (S4) including at least one of the steps (S42) of driving a plurality of nails (shingle nails) at intervals along the length direction or the width direction of the roof finishing material (F) may be further included. .

After the step (S42), the protruding portion of the nail may be finished with an exterior aqueous sealant or the like.

This sheet should be protected from direct sunlight or rain and snow during storage, and it is desirable that the storage temperature does not exceed 35℃. In winter, it should be stored for at least 1 day in a warehouse with a temperature over 10℃ prior to construction before use.

When transporting and storing this sheet, handle it upright, and after construction, the waterproof adhesive layer (1) must be thoroughly protected and managed to prevent damage to the waterproof adhesive layer (1) due to other construction. Also, do not walk on this seat wearing shoes that have dirt or foreign substances on them.

5 is a view for explaining a further embodiment of the present invention.

On the other hand, the waterproof adhesive layer (1) contains 1.0 parts by weight of the functional additive (G) compared to 100 parts by weight of the asphalt. The functional additive (G) is 0.2 parts by weight of the stretchable outer material (G1) containing latex, 0.4 parts by weight of the variable material (G2) containing bismuth nickel iron oxide, magnetite, polyacrylic acid ), 0.2 parts by weight of a cationic material (G3) containing polyoxyethylene, 0.2 parts by weight of an anionic polymer material (G4) containing p-styrenesulfonic acid (SSNa) (G4) 0.2 parts by weight can do. (The ratio of each component of the functional additive (G) was based on 100 parts by weight of asphalt).

In addition, the stretchable envelope (G1) is fibrous, the variable material (G2) is accommodated in the interior of the envelope (G1) in the form of particles, the cation material (G3) is the amount of the stretchable envelope (G1) It is provided at any one of the side ends, and the anionic polymer material (G4) may be provided at the other end of both side ends of the stretchable outer material (G1).

Referring to FIG. 5 , the functional additive G will be described in more detail. The stretchable outer material G1 includes latex that is elastically deformable in order to respond to a volume change of the variable material G2 to be described later.

When the amount of the elastic covering material (G1) is less than 0.2 parts by weight, there is a risk that the variable material G2, which will be described later, including 0.4 parts by weight, cannot be sufficiently wrapped with a sufficient thickness, so that the variable material G2 may be lost, and the stretchable sheath material G1 When it exceeds 0.2 parts by weight, the weight of the functional additive (G) is excessively increased to reduce the dispersibility because the functional additive (G) moves downward in the waterproof adhesive layer (1) (corresponding to reference numeral GS in FIG. 5). There is a problem.

Components except for the functional additive (G) in the waterproof adhesive layer (1) generally increase in volume as the temperature increases. However, the volume of bismuth nickel iron oxide (BiNi1-xFexO3) included in the variable material G2 and which is an oxide ceramic material decreases as the temperature increases. Bismuth nickel iron oxide was used because it has a 'negative thermal expansion' effect that is more than twice that of conventional materials (eg, zirconium vanadate) at room temperature.

[A] of Figure 5 is a view for explaining the functional additive (G) at a first temperature of room temperature (for example, 10 ℃). [B] of FIG. 5 is a view for explaining the functional additive (G) at a second temperature (eg 20 °C) higher than the first temperature of room temperature.

In FIG. 5, when the waterproof adhesive layer 1 rises from the first temperature to the second temperature, the components other than the functional additive (G) in the waterproof adhesive layer 1 (corresponding to the reference numeral GS in FIG. 5) have a volume will increase In this case, the components other than the functional additive (G) in the waterproof adhesive layer (1) may be bent and wrinkled, thereby reducing adhesion and may cause peeling.

The functional additive (G) is to suppress the volume increase of the waterproof adhesive layer (1) (components excluding the functional additive (G)) according to the temperature rise, the variable material (G2) is the temperature rises as described above As a result, the volume decreases.

It is said that the stretchable outer material G1 is a material that is elastically deformed, and as the volume of the above-described variable material G2 is reduced as shown in [B] of FIG. In this way, the waterproof adhesive layer 1 includes a functional additive (G) including a variable material (G2), so that the waterproof adhesive layer 1 changes in volume according to the temperature change (or in the horizontal direction (with reference to FIG. 5 ). It has the advantage of suppressing the stretching in the left and right)) to suppress the bending or wrinkling, and effectively suppressing the occurrence of peeling through this.

In the functional additive (G), it is preferable that 0.4 parts by weight of the variable material (G2) is used, but when less than 0.4 parts by weight of the variable material (G2) is used, the change in volume of the waterproof adhesive layer 1 cannot be effectively suppressed. If the variable material (G2) exceeds 0.4 parts by weight, the variable material (G2) cannot all be accommodated in the stretchable outer material (G1), so there is a risk of loss of the variable material (G2), and the weight of the functional additive (G) There is a problem in that the dispersibility of the functional additive (G) is reduced by excessively increasing the .

The variable material G2 is preferably in the form of particles, and a plurality of variable materials G2 in the form of particles may be accommodated in the fibrous stretchable outer covering G1. In this way, since the variable material (G2) has a plurality of particle shapes, it is free to move, so it is possible to change the shape of the flexible outer material (G1) that is fibrous and elastically deformable, and the waterproof adhesive layer (1) is applied to the roof. There is an advantage that the shape of the functional additive (G) can also be variously changed in response to the shape. More specifically, in FIG. 5, the functional additive (G) has a '-' shape, but may be bent and changed into various shapes such as a 'L', 'B', and 'S' shape. That is, it is possible to improve the adhesion of the waterproof adhesive layer (1).

In addition, the outer shell material (G1) of the functional additive (G) is an elastic material, and as described above, it is fibrous, so it is possible to add toughness to the waterproof adhesive layer 1, and the waterproof adhesive layer 1 is torn or damaged. There is an advantage that it can be effectively suppressed.

The cationic material G3 is provided at either end (right end in FIG. 5) of both ends of the stretchable outer material G1. As described above, magnetite, polyacrylic acid) And adding a positive polarity to either side of the functional additive (G), including polyoxyethylene (polyoxyethylene).

Magnetite becomes magnetic when it receives an external magnetic field, and when the external magnetic field is removed, the residual magnetism disappears, so there is no side effect due to the residual magnetism. The magnetite may be provided on either end side of the stretchable envelope G1.

Polymethacrylic acid is coated on the surface of the magnetite, and contains a plurality of carboxyl groups to form a coordination bond with the magnetite at multiple bonding points, so coating stability can be improved.

Polyoxyethylene may react with a carboxyl group that does not form a coordination bond with magnetite on the surface of polymethacrylic acid to form a stable bond through an amide bond to impart positive charge properties to the magnetite. The positive surface charge of the cation material G3 may have a surface zeta potential of +30 mV or more.

It is preferable that 0.2 parts by weight of the cationic material (G3) is used, but when it is less than 0.2 parts by weight, the positive charge is not sufficient, and when it exceeds 0.2 parts by weight, there is a problem in that the weight of the functional additive (G) is excessively increased.

The anionic polymer material (G4) is provided on the other side of both ends of the stretchable outer material (G1), and may include p-styrenesulfonic acid as described above, in addition to adding a hydrogel pre-polymer may include

The anionic polymer material (G4) may be a mixture of p-styrenesulfonic acid and hydrogel pre-polymer (ratio 1:19) and UV-cured.

It is preferable that 0.2 parts by weight of the anionic polymer material (G4) is included. When less than 0.2 parts by weight is used, the negative charge is not sufficient, and when it exceeds 0.2 parts by weight, the weight of the functional additive (G) is excessively increased to improve dispersibility. There is a problem of lowering it.

When a large number of units (GU) of the functional additive (G) are included in the waterproof adhesive layer (1), the neighboring units (GU) are separated by shear force in a stirring (mixing) situation to improve the dispersibility of each component in the present composition (Asphalt exists in a liquid state at a high temperature of about 50℃)

As described above, the functional additive (G) is said to include the anionic polymer material (G4) of the cationic material (G3) at both ends of the stretchable outer material (G1), respectively, after mixing, in the waterproof adhesive layer (1) Units (GU) can be attached by electrostatic attraction, and in this case, the waterproof adhesive layer (1) is an electrostatic force between the fibrous stretchable outer material (G1) as well as the cationic material (G3) and the anionic polymer material (G4). Toughness can be imparted by manpower.

At this time, the magnetite of the cationic material (G3) is a mineral, and there is a risk of being damaged by impact. The anionic polymer material (G4) is a polymer material, which is basically easier to deform than a mineral, so that the neighboring unit (GU) is caused by electrostatic attraction. The shape of the anionic polymer material (G4) is changed by the cationic material (G3) when attached to each other. Therefore, since the impact applied to the cation material (G3) is reduced, it is possible to effectively suppress the damage of the functional additive (G).

The present invention described above with reference to the accompanying drawings is capable of various modifications and changes by those skilled in the art, and such modifications and changes should be construed as being included in the scope of the present invention.
