The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms as used herein include plural forms as long as the phrases do not expressly express the opposite meaning thereto. Means that a particular feature, region, integer, step, operation, element and / or component is specified, and that other specific features, regions, integers, steps, operations, elements, components, and / And the like.

Unless otherwise defined, all terms including technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Commonly used predefined terms are further interpreted as having a meaning consistent with the relevant technical literature and the present disclosure, and are not to be construed as ideal or very formal meanings unless defined otherwise.

Hereinafter, a wall surface finishing tape according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a perspective view of a conventional gypsum board for a gypsum board. As shown in FIG. 1, a conventional gypsum board for a gypsum board has a coating layer 12 formed on a base paper 11 at a central portion thereof, and a bonding portion 13 formed on both sides of the coating layer 12. The gypsum board-use gypsum board functions to complement the steps or cracks inevitably generated when the gypsum board is installed, thereby preventing damage to the later installed gypsum board. At this time, the coating portion 12 is a part that plays a key role, and corresponds to a portion having flexibility, elasticity and elasticity according to the relaxation and shrinkage of the gypsum board. Such a coated portion is a portion formed by a coating liquid suitable for a purpose.

2 is a view showing a state in which a conventional gypsum board for a gypsum board is installed. First, a step may be formed on the wall surface W of the gypsum board. If the putty work or the paint work is directly performed on such a step, the step is exposed to the outside, and the appearance is not good. In order to fill the step of the wall surface W, the inlay 20 is first attached to the stepped portion of the wall surface. So that the step is not exposed to the outside. Then, the gypsum board insert 10 is attached to the stepped portion. The coating portion 12 is placed on the stepped portion and attached to the wall surface by the adhesive portion 13 formed on both sides of the raw paper 11. [ A predetermined tension is operated by the coating portion 12 of the gypsum board for paper board 10, and a predetermined space is maintained in the portion where the step is formed with the coating portion 12. [ Therefore, the level difference is reduced primarily by the inlaying, and the level difference exposed to the outside by the coating part 12 is eliminated secondarily.

Such gypsum boards can be exposed to moisture after construction. In particular, in the case of a toilet having a large amount of moisture, it is affected by the internal moisture which can be formed in the gaps between the gypsum boards and the external moisture generated in the room. Especially, when the wall surface is the ceiling, the paper is influenced by the moisture generated in the lower part, and the problem of falling down in the gravity direction may occur. As described above, since the raw paper contains moisture due to moisture, the surface of the papermaking paper is made to be painted or the outer surface of the papermaking floor is crooked, resulting in a non-smooth surface, which requires repairing.

The present inventor has completed the present invention by focusing on the fact that the effect of moisture in this case can be minimized by installing the coating portion in the indoor side so as to cope with moisture generated on the indoor side.

3 is a perspective view of a wall finish tape according to an embodiment of the present invention. Referring to FIG. 3, a wall surface finishing tape 100 according to an embodiment of the present invention is a tape that is adhered to a step or a crack portion formed on a wall surface to be finished and includes a base paper 110, a bonding portion 130, ).

The term " wall surface " as used herein includes that a certain surface such as a wall, a ceiling, and a floor inside the building is formed. Also, the stepped portion formed on the wall surface refers to a portion having a difference in height due to a portion formed by connecting the interior material for wall construction or a portion connected by concrete construction or the like. In addition, it can be applied to all parts that need to be finished with paint and gauze indoors. Also, cracks may be gaps or broken portions generated between gypsum boards to be installed, and may be various types of internal damages caused by external forces of buildings. It can be used as long as it is a portion where a certain amount of gold is separated from the amount of gold, and is not limited to any particular place.

The paper sheet 110 is for constituting a basic form of the wall surface finishing tape 100. Various paper having a predetermined width and length may be used depending on the application. In addition, although the thickness of the raw paper 110 may be lowered, it is possible to reduce a degree of exposure of the wall surface to a step or a crack, but since the tape form may be exposed to the outside after painting or after attaching wallpaper, . The raw paper 110 may be a resin-treated raw paper. Resin treatment of the paper (110) has water resistance and durability of the papermaking paper to prevent tearing and deformation after finishing the seam of the wall, and it is possible to absorb the paint on the upper surface by the moisture according to the temperature difference, This is to prevent flooded walls or ceilings from floating.

The coating unit 120 is a part that plays a key role in the present invention and has a certain flexibility, elasticity, and water repellency. The coating unit 120 is also provided to prevent deformation due to moisture, . In particular, when the coating liquid is formed of a hydrophobic coating liquid, the paper can be prevented from being deformed due to moisture generated in the room. Further, deformation of the paper 110 due to application of heavy and large particles such as gypsum plaster, putty, etc., can be prevented.

The coating liquid preferably includes an acrylic resin. Acrylic resin provides the basic mechanical strength of the coated part of the wall finish tape and is excellent in weather resistance. Even when the wall is closed by the wall surface finishing tape, Can be prevented from being deformed.

Basically, the content of the acrylic resin in the coating liquid is preferably 20 to 60% by weight. When the content of the acrylic resin is less than 20% by weight, the effect of preventing the deformation against the environmental change is insignificant. When the content of the acrylic resin is more than 60% by weight, It is limited to the above range.

In addition, toluene (Toluene) disperses the acrylic resin (acrylic resin) to spread evenly on the surface of the raw paper, and plays a role of absorbing an appropriate amount of the resin mixed with the raw paper. Toluene is a colorless, volatile liquid that must be sealed when stored and it is possible to control the viscosity of the coating solution by controlling the content of toluene (Toluene).

Toluene can be adjusted as needed, but it is preferably 40 to 80% by weight. When the content of toluene is low, the viscosity of the coating solution is high, so that it is difficult to coat and the coating layer may be formed non-uniformly. When the viscosity of the coating solution is low due to the high content of toluene, There is a problem that the strength of the wall surface finishing tape can not be maintained and the wall surface finishing tape can not be performed.

The coating liquid may additionally contain an additive as required, as well as an acrylic resin (acrylic resin) and toluene (Toluene). Silicone oil (KF96) is excellent in releasability and water repellency and may be included to prevent foreign substances such as rosewood from adhering to the coating layer. Particularly, such silicone oil (KF96) can prevent the stepped portion formed by the non-adhesive space between the wall surface finishing tape and the wall surface, and prevent wall depression or tearing. Such silicone oil (KF96) may be added in an amount of 5 to 15% by weight. If the content of the silicone oil (KF96) is less than 5% by weight, the releasability and water repellency may not be exhibited. If the content of the silicone oil (KF96) is more than 15% by weight, dissolution with other materials may be difficult.

Further, wax may be further added to perform a function similar to that of silicone oil (KF96). When such a wax is added to a coating solution, the coated paper is dried well and serves as a release agent. The addition amount of the wax is preferably 5 to 15% by weight. If the wax is added in excess, it may adhere to the wall surface due to good adhesion to the gypsum paste.

Adhesive parts 130 are formed on both sides of the opposite side of the coating part 120 so that the adhesive part 130 can be formed. Since the adhesive 130 does not require a separate adhesive and the finished portion is finished in a straight line, the paint can be directly applied onto the wall finish tape, so that the coating can be finished in a short time without harming the aesthetics. And time can be shortened. Such a bonding portion can be usually formed by a roasting paste or a flour paste, and is not limited to a specific adhesive. Particularly, it is possible to form the adhesive portion by using an adhesive which does not have an adhesive force when dried for convenience of use, but an adhesive force is generated when water is added to reproduce the adhesive force and can be used.

A method for manufacturing a wall surface finishing tape according to an embodiment of the present invention will be described.

First, prepare the paper to make the wall finishing tape. Resin treated paper can be used. The thus prepared raw paper is coated with a coating solution containing an acrylic resin to form a coated portion. The coating liquid is prepared as described above. It is possible to continuously form the coating layer on the base paper by passing the base paper through the coating solution by being put on a roll. At this time, the viscosity of the coating liquid at room temperature (25 degrees Celsius) is preferably about 30 seconds on the basis of a Ford Cup viscosity measuring instrument. The viscosity of the coating fluid varies between 25 and 35 seconds depending on the resin condition, the humidity, and the temperature of the coating equipment. At this time, the controlled viscosity can be controlled by the amount of toluene contained. If the temperature is high, the viscosity may be somewhat increased due to the characteristics of the highly volatile solvent. In this case, it is necessary to keep the viscosity constant by storing the coating liquid in the closed container.

After the coating solution is coated on the paper, the paper is dried. Such a drying process may include natural drying using natural wind, drying at room temperature, thermal drying using a hot roll, and cold drying using a roll at room temperature.

Natural drying is the first of the process in which the coated paper is subjected to several rolls and is dried at room temperature through a fan or the like which can generate a constant wind. The primary dried sheet is then passed through a drying roll maintained at a temperature of about 90 to 100 degrees to heat the backside of the coated sheet to dry the sheet. At this time, the acrylic resin is thermally cured to have the required strength of the coating portion. At this time, the moving speed of the paper is about 26 ~ 30 M / min. The thermally dried substrate is subjected to cold drying through a roll at room temperature where no heat is provided. At this time, the coated portion of the paper is completely dried, and the paper does not stick to each other even if dried.

The dried paper is cut to the required size. Usually, gypsum board can be cut into two types, 12 cm in width and 15 cm in width. The width of the coating is about 9 cm and 12 cm. The cut backs are applied on both sides so that the adhesive portion can be formed on both sides of the opposite side where the coated portion is formed. This bonding part eliminates the need for a separate adhesive and finishes the finished part straightly, so that it can be painted using paint directly on the wall finishing tape, so that it can be finished in a short time without harming the aesthetics. Can be shortened. Such adhesives can also be used as a planting or flour paste, etc.

At this time, the dried raw paper can be further compressed by a machine to improve the smoothness of the coating liquid. In this case, by minimizing the occurrence of variation in the thickness of the coating portion, it is possible to prevent tearing or breakage of the wall surface finishing tape when it is attached to the wall surface.

4 is a view showing a state in which a wall surface finishing tape according to an embodiment of the present invention is installed. Referring to FIG. 4, a step is formed on a wall surface W formed with a gypsum board. And may be attached to a portion where a stepped portion is formed on the wall surface W by using an inlay to reduce a step. A wall finishing tape 100 is attached to the step portion, wherein the coating portion 120 is formed on the opposite surface of the paper sheet 110, which is not a step portion. And a bonding portion 130 is formed on the opposite side of the portion where the coating portion 120 is formed. The inlay is attached to the entire surface of the joint or crack face of the wall surface, and the inlay and the paper are not bonded to each other without adhesion and form a fine space. It is possible to prevent the step from being exposed from the upper part of the gypsum board by preventing the movement of the steps and the moisture from the upper part of the gypsum board by forming the fine space through the non- It is possible to minimize the cracking of the finishing material due to the movement of the gypsum board step. The inlay may be separately attached to the gypsum board step portion, but may be attached to the wall surface finishing tape according to the present invention. That is, if the inlay is positioned between the adhesive portions of the wall surface finishing tape and then the inlay is wound, it is possible to attach the inlay to the step portion at the same time when attaching the wall surface finishing tape.

When the sheet 110 is attached to the wall W in this form, the sheet 110 is not directly exposed to moisture generated in the downward direction. The coating part 120 formed on the undersurface of the base sheet 110 prevents the moisture from being absorbed by the base sheet 110 and the part exposed on the opposite side of the bonding part 130 is formed by the wall surface W and the adhesive part 130, It is possible to prevent the base paper 110 from being deformed even if the base paper 110 is exposed to moisture generated in the lower portion.

5 is a view showing another example of construction of a wall surface finishing tape according to an embodiment of the present invention. Referring to FIG. 5, it is possible to attach the inlay 200, which is primarily attached to the stepped portion, so that the coating layer 220 is formed on the paper layer 210. The coating layer 220 formed on the inlay 200 to be adhered is formed of a coating liquid in the same manner as the coating portion 120 on which the wall finish tape 100 is formed and the details are the same as those of the coating portion of the wall finish tape . When the coating layer is additionally formed on the inlay, it prevents the deformation of the inlay by the moisture generated on the side where the step is formed.

When the wall surface finishing tape according to the embodiment of the present invention is applied even in a place where moisture is generated in the room as described above, the tape itself is prevented from being deformed by the moisture in the room, and thus the long time construction state can be maintained. Further, when the painting operation is performed after the wall surface is finished with the wall surface finishing tape, it is possible to omit inconvenient processes such as performing a large number of putty operations, thereby improving the working efficiency.

Hereinafter, a wall surface finishing method according to an embodiment of the present invention will be described in detail

6 is a flowchart of a method of a wall surface finishing method according to an embodiment of the present invention. Referring to FIG. 6, a wall surface finishing method according to an embodiment of the present invention includes the steps of (S11) attaching an inlay to a crack or a joint formed on a wall by using a primary coating, (S12) of attaching a wall surface finishing tape so that the adhesive portion adheres to a portion of the wall surface finishing tape (S12); and applying paint after attaching the wall surface finishing tape (S13).

First, the inlay is attached to the cracks or joints formed on the wall by using the primary clay. Here, cracks and joints correspond to portions formed by joining interior materials such as gypsum board. As described above, not only the paper material but also the coating layer may be used. The step can be reduced primarily by inlay. A tape for finishing the wall is attached so that the adhesive portion adheres to both sides of the portion to which the inlay is attached. At this time, the wall surface finishing tape is provided with a base paper having a predetermined length and width, a bonding portion formed on both sides of a surface of a raw paper adhered to the wall surface so as to be attached to a step or a crack portion formed on the wall surface, And a coating portion formed at a position corresponding to a step or a crack portion formed on the wall surface.

Referring to FIG. 7, a wall surface finishing method according to an embodiment of the present invention includes the steps of (S21) sanding a crack portion generated on a wall surface, (S22) applying an intermediate coating agent to the sanded crack portion, A step (S23) of attaching a wall surface finishing tape so that the adhesive portion adheres to both sides of the coated portion, and a step (S24) of applying paint after attaching the wall surface finishing tape.

First, the cracks generated on the wall can be cracks generated by the own load of the building, and various kinds of cracks are targeted. In particular, sanding work is performed by using a sanding paper or the like to flatten the cracks whose surface is not constant. After the planarization by the sanding work, the intermediate agent is applied to the crack portion. The intermediate agent forms a uniform coating layer on the wall surface to prevent the drop of the wall surface finishing tape due to moisture, and the adhesive force of the wall surface finishing tape is stronger and lasts longer. The midrange system can be used with various midrange systems commercially available.

After the intermediate agent is applied, a wall surface finishing tape is attached to both sides of the portion to which the intermediate agent is applied so that the adhered portion is in close contact. At this time, the wall surface finishing tape is provided with a base paper having a predetermined length and width, a bonding portion formed on both sides of a surface of a raw paper adhered to the wall surface so as to be attached to a step or a crack portion formed on the wall surface, And a coating portion formed at a position corresponding to a step or a crack portion formed on the wall surface. After attaching the wall surface finishing tape, the paint is applied to finish the wall surface. Cracks that are performed in this way are those that form on the ceiling or walls of a building and that have cosmetic problems that are not related to safety. In this way, it is possible to smoothly repair the surface easily when the cracked wall surface is closed.
