Description

Differential tape and method of using same

The present invention relates to a differential tape and a method of using the same.

An adhesive is a substance that bonds an object to an object, and after the curing is over time, the adhesive disappears completely. On the other hand, a pressure-sensitive adhesive refers to a substance that adheres an object and an object together, such as an adhesive, but does not change property over time.

Generally, a double-sided tape can be used when the object and the object are in contact with each other. However, in the case of such a double-sided tape, the same pressure-sensitive adhesive is applied to both sides, so that it has been used to bond two objects or more regardless of the direction of the double-sided tape.

However, depending on its use, the adhesive on both sides may have different components, which may require different double-sided tapes.

Referring to Figs. 1 and 2, a differential tape according to some embodiments of the present invention will be described.

FIG. 1 is a perspective view for explaining a differential tape according to some embodiments of the present invention, and FIG. 2 is a sectional view cut along C-C 'of FIG.

Referring to FIG. 1, a differential tape according to some embodiments of the present invention includes a substrate 100, a permanent adhesive layer 200, and a removable adhesive layer 300.

The substrate 100 may include first and second surfaces facing each other. In this case, the first surface and the second surface may mean both surfaces facing each other such as up, down, left, and right. For convenience, the first surface of the substrate 100 is defined as the surface in the direction A in the drawing, and the second surface of the substrate 100 is defined as the surface in the direction B in the drawing.

The substrate 100 may include any one of a nonwoven substrate, an image substrate, a cloth substrate, a tear film substrate, a bare substrate substrate, a PE foam substrate, a urethane foam substrate, and a PE film substrate.

The substrate 100 may be easily cut to any size. That is, the substrate 100 can be easily cut by the user to any desired size of the substrate 100 and used as a plurality of pieces. The substrate 100 can be easily cut using a user's hand or the like. Thus, the user can cut the substrate 100 to a desired size without any other tool.

Further, the base material 100 can be cut into an arbitrary shape. The substrate 100 can bond or adhere two objects to each other by using the permanent adhesive layer 200 and the removable adhesive layer 300 formed on the first surface and the second surface, There are no restrictions on the shape.

The substrate 100 may be transparent. As a result, even when adhered to an object to be adhered, the surface of the object to be adhered can be identified. However, the present invention is not limited thereto.

The permanent adhesive layer 200 may be formed on the first surface of the substrate 100. The permanent adhesive layer 200 may be an adhesive layer which is formed so as to be completely adhered to and separated from an object to be adhered. That is, the permanent adhesive layer 200 can use a permanent adhesive having a relatively stronger adhesive strength than the rigid adhesive of the rimmed adhesive layer 300 described later.

The permanent adhesive layer 200 may be formed to completely cover the first surface of the base material 100 on the first surface of the base material 100. An object attached to the first surface of the substrate 100 may be completely bonded to the substrate 100 and may not be separated at a later time. That is, an object that is in contact with and bonded to the permanent adhesive layer 200 can be completely bonded to the substrate 100.

The permanent adhesive of the permanent adhesive layer 200 may include, for example, 2-ethylhexyl acrylate, butyl acrylate, vinyl acetate and acrylic acid. The permanent adhesive layer 200 may be a solvent type, not an aqueous emulsion type. However, the present invention is not limited thereto.

Specifically, the permanent adhesive layer 200 may contain 30% to 40% of 2-ethylhexyl acrylate. However, the present invention is not limited thereto. The permanent adhesive layer 200 may contain 40 to 50% of butyl acrylate. However, the present invention is not limited thereto. The permanent adhesive layer 200 may contain 5 to 10% of vinyl acetate. However, the present invention is not limited thereto. The permanent adhesive layer 200 may contain acrylic acid in an amount of 1 to 5%. However, the present invention is not limited thereto.

A rimmed adhesive layer (300) may be formed on the second surface of the substrate (100). Accordingly, the rimmed adhesive layer 300 and the permanent adhesive layer 200 may be formed on both sides of the substrate 100 so as not to contact each other.

The rimmed adhesive layer 300 may be an adhesive layer that is formed to be desorbed and reattached several times to an adhered object. That is, the rimmed adhesive layer 300 can use a rimmed adhesive having a relatively weaker adhesive strength than the permanent adhesive of the permanent adhesive layer 200.

The rimmed adhesive layer 300 may be formed to completely cover the second surface of the substrate 100 on the second surface of the substrate 100. [ An object attached to the second surface of the substrate 100 may be temporarily bonded to the substrate 100 and subsequently separated. That is, an object contacting and bonding to the removable adhesive layer 300 can be freely detached and attached to the base material 100. The rimmed adhesive layer 300 may not leave any traces at the time of desorption. That is, no trace of the pressure-sensitive adhesive is left on an object contacting with the rimmed adhesive layer 300, so that a clean surface can be maintained.

The rimless adhesive of the rimmed adhesive layer 300 may include, for example, 2-ethylhexyl acrylate, butyl acrylate, methyl acrylate, acrylic acid, glycidyl methyl acrylate and N-methylol acrylamide . The rimmed adhesive layer 300 may be a solvent type, not an aqueous emulsion type. However, the present invention is not limited thereto.

Specifically, the rimmed adhesive layer 300 may contain 40% to 50% of 2-ethylhexyl acrylate. However, the present invention is not limited thereto. The rimmed adhesive layer 300 may contain 20 to 30% of butyl acrylate. However, the present invention is not limited thereto. The rimmed adhesive layer 300 may contain 10 to 20% of methyl acrylate. However, the present invention is not limited thereto. The rimmed adhesive layer 300 may contain acrylic acid in an amount of 1 to 8%. However, the present invention is not limited thereto. The rimmed adhesive layer 300 may contain 1 to 5% of glycidylmethyl acrylate. However, the present invention is not limited thereto. The rimmed adhesive layer 300 may contain from 1 to 5% of N-methylol acrylamide. However, the present invention is not limited thereto.

The rimmed adhesive layer 300 and the permanent adhesive layer 200 may include different materials. For example, methyl acrylate, glycidyl methylacrylate, and N-methylol acrylamide are included in the removable adhesive of the removable adhesive layer 300, but not included in the permanent adhesive of the permanent adhesive layer 200 . On the contrary, vinyl acetate is included in the permanent adhesive of the permanent adhesive layer 200, but may not be included in the removable adhesive of the removable adhesive layer 300. However, the present invention is not limited thereto.

Though not limited thereto, the thickness T1 of the base material 100 may be thinner than the thickness T2 of the permanent pressure-sensitive adhesive. The thickness T1 of the base material 100 may be thicker than the thickness T3 of the rigid pressure sensitive adhesive. The thickness (T1) of the base material 100 may have a range of, for example, 5 탆 to 125 탆 . However, the present invention is not limited thereto.

If the thickness (T1) of the base material 100 is thinner than 5 占 퐉, the manufacturing cost increases and it may not be possible to perform the function of supporting the pressure sensitive adhesive applied on both sides. On the contrary, when the thickness T1 of the base material 100 is thicker than 125 탆, it may be difficult for the user to cut easily, and the distance between the objects adhered to both surfaces may be distant, and the adhesion between the two objects may be weakened.

The thickness T2 of the permanent adhesive layer 200 may be thicker than the thickness T3 of the removable adhesive layer 300. [ The permanent adhesive of the permanent adhesive layer 200 may have a stronger adhesive force than the adhesive force of the rimmed adhesive of the removable adhesive layer 300. [ This is because, even when the object attached to the rimmed adhesive layer 300 is repeatedly attached and detached, the object can be fixed with a relatively strong adhesive force with the object attached to the permanent adhesive layer 200. However, the present invention is not limited thereto.

The thickness of the permanent adhesive layer 200 may be, for example, in the range of 2 탆 to 120 탆 . However, the present invention is not limited thereto.

If the thickness T2 of the permanent adhesive layer 200 is thinner than 2 占 퐉, the manufacturing cost increases and it may be difficult to fix the permanent adhesive layer 200 to an object attached to the permanent adhesive layer 200. [ On the contrary, when the thickness T2 of the permanent adhesive layer 200 is thicker than 120 m, the permanent adhesive applied to the base material 100 may not be held in a fixed form by its own weight.

The thickness of the removable adhesive layer 300 may range, for example, from 2 m to 120 m . However, the present invention is not limited thereto.

If the thickness T3 of the removable adhesive layer 300 is thinner than 2 mu m, the manufacturing cost is increased and adhesion with an object attached to the removable adhesive layer 300 may be difficult. On the contrary, when the thickness T3 of the removable adhesive layer 300 is thicker than 120 m, the permanent adhesive applied to the base material 100 may not be held in a fixed form by its own weight.

The differential tapes according to some embodiments of the present invention may be formed of different pressure sensitive adhesive components on both sides and used for different purposes. For example, a photo may be attached to the permanent adhesive layer 200 and attached to the wall using the rimmed adhesive layer 300. Accordingly, the photograph can be attached to a desired portion of the wall, and can be detached again, and then reattached.

Alternatively, a painting operation can be performed by attaching the masking film to the permanent adhesive layer 200 and attaching the rimmed adhesive layer 300 to the vehicle or the furniture in the painting of the vehicle or the painting of the furniture. Upon completion of the painting operation, the second surface of the substrate 100 adhered to the rimmed adhesive layer 300 can be separated from the vehicle or the furniture. The remover adhesive layer 300 can be easily removed without leaving any traces when it is detached.

Hereinafter, referring to Fig. 3, a differential tape according to some embodiments of the present invention will be described. The parts overlapping with the above-described embodiment are omitted or briefly described.

3 is a cross-sectional view for explaining a differential tape according to some embodiments of the present invention.

Referring to FIG. 3, the differential tape according to some embodiments of the present invention may further include a first release liner 400a.

The first release liner 400a may be formed on the permanent adhesive layer 200. [ The first release liner 400a can be removed before being adhered to the adherend to expose the permanent adhesive layer 200. [

The first release liner 400a may be a film obtained by subjecting a film such as paper, polyethylene, polypropylene, or polyethylene terephthalate to peeling treatment with the permanent adhesive layer 200 to enhance releasability. The material used for the peeling treatment of the first release liner 400a of the present embodiment is not particularly limited, and for example, materials such as fluoro silicone, long-chain alkyl vinyl monomer polymer, and aminoalkyd resin can be used.

The thickness T4a of the first release liner 400a is not particularly limited, but may be, for example, usually in the range of 25 mu m to 150 mu m.

Hereinafter, referring to Fig. 4, a differential tape according to some embodiments of the present invention will be described. The parts overlapping with the above-described embodiment are omitted or briefly described.

4 is a cross-sectional view for explaining a differential tape according to some embodiments of the present invention.

Referring to FIG. 4, the differential tape according to some embodiments of the present invention may further include a second release liner 400b.

The second release liner 400b may be formed on the rimmed adhesive layer 300. [ The second release liner 400b may be removed to expose the rimmed adhesive layer 300 before being adhered to the adherend.

The second release liner 400b may be a film obtained by subjecting a film such as paper, polyethylene, polypropylene, polyethylene terephthalate or the like to a release treatment for improving releasability with the permanent adhesive layer 200. The material used for the peeling treatment of the second release liner 400b of the present embodiment is not particularly limited, and for example, materials such as fluoro silicone, long-chain alkyl vinyl monomer polymer, and aminoalkyd resin can be used. That is, the second release liner 400b may include the same material as the first release liner 400a, but is not limited thereto.

The thickness T4b of the second release liner 400b is not particularly limited, but may be in the range of usually 25 mu m to 150 mu m, for example.

Hereinafter, referring to Fig. 5, a differential tape according to some embodiments of the present invention will be described. The parts overlapping with the above-described embodiment are omitted or briefly described.

Referring to FIG. 5, the differential tape according to some embodiments of the present invention may include both the first release liner 400a and the second release liner 400b.

Hereinafter, a differential tape according to some embodiments of the present invention will be described with reference to FIGS. 6 and 7. FIG. The parts overlapping with the above-described embodiment are omitted or briefly described.

FIG. 6 is a perspective view for explaining an air cell layer combined with a differential tape according to some embodiments of the present invention, and FIG. 7 is a sectional view for explaining a differential tape according to some embodiments of the present invention

Referring to FIG. 6, the air cell layer 500 may include an air cell 520 and a sheet 510. The air cell 520 may be in the form of a cell including air 520a therein. The air cell 520 may be in the form protruding from the sheet 510. However, the present invention is not limited thereto.

The sheet 510 and the air cell 520 may be formed of vinyl. The sheet 510 and the air cell 520 can be used as a cushioning material and an insulating material through a buffering action and an insulating action.

Referring to FIG. 7, the differential tape according to some embodiments of the present invention may further include an air cell layer 500 on the differential tape of FIG.

The air cell layer 500 may be attached to the permanent adhesive layer 200 on the permanent adhesive layer 200. Accordingly, the air cell layer 500 and the base material 100 can be completely fixed to each other. The base material 100 may be adhered to a window or the like by the rimmed adhesive layer 300. Through this, a differential tape including the air cell layer 500 can be easily attached to a window or the like. Through this, the differential tape of the present invention can be used as a heat insulating material for winter winter.

In the differential tape of the present invention, it is also possible to easily change the position of the bar attached to the window or the like by the rimmed adhesive layer 300. In addition, even if the differential substrate 100 is removed from the window after the winter, no traces are left, and it can be removed neatly.

Hereinafter, a differential tape according to some embodiments of the present invention will be described with reference to Figs. 6 and 8. Fig. The parts overlapping with the above-described embodiment are omitted or briefly described.

8 is a cross-sectional view for explaining a differential tape according to some embodiments of the present invention.

Referring to FIG. 8, the protruding portion of the air cell 520 of the air cell layer 500 according to some embodiments of the present invention may be in contact with the permanent adhesive layer 200. Accordingly, the sheet 510 of the air cell layer 500 may not contact the permanent adhesive layer 200.

A space 530 may be formed between the sheet 510 of the air cell layer 500 and the substrate 100. The space 530 can further enhance the thermal insulation effect with the air cell 520. [ That is, the air located in the blank space 530 may reduce the transfer of the temperature between the window and the inside of the window to increase the heat insulating effect.

Accordingly, the differential tape according to some embodiments of the present invention can achieve a higher adiabatic effect through one air cell layer 500.

Hereinafter, a method of using the differential tape according to some embodiments of the present invention will be described with reference to Figs. 1, 2, and 9. The portions overlapping with the embodiment of the differential tape described above are simplified or omitted.

9 is a flowchart for explaining a method of using a differential tape according to some embodiments of the present invention.

Referring to FIG. 9, a differential tape is provided (S100).

1, the differential tape includes a base material 100, a permanent adhesive layer 200, and a removable adhesive layer 300. As shown in FIG.

That is, the permanent adhesive layer 200 can use a permanent adhesive having a relatively stronger adhesive strength than the rigid adhesive of the rimmed adhesive layer 300 described later.

The permanent adhesive layer 200 may be formed to completely cover the first surface of the base material 100 on the first surface of the base material 100. An object attached to the first surface of the substrate 100 may be completely bonded to the substrate 100 and may not be separated at a later time. That is, an object that is in contact with and bonded to the permanent adhesive layer 200 can be completely bonded to the substrate 100.

A rimmed adhesive layer (300) may be formed on the second surface of the substrate (100). Accordingly, the rimmed adhesive layer 300 and the permanent adhesive layer 200 may be formed on both sides of the substrate 100 so as not to contact each other.

The rimmed adhesive layer 300 may be an adhesive layer that is formed to be desorbed and reattached several times to an adhered object. That is, the rimmed adhesive layer 300 can use a rimmed adhesive having a relatively weaker adhesive strength than the permanent adhesive of the permanent adhesive layer 200.

Referring again to FIG. 9, the differential tape is cut into a first shape (S200).

The first shape means any shape that can be cut. That is, the substrate 100 can be easily cut to an arbitrary size. That is, the substrate 100 can be easily cut by the user to any desired size of the substrate 100 and used as a plurality of pieces. The substrate 100 can be easily cut using a user's hand or the like. Thus, the user can cut the substrate 100 to a desired size without any other tool.

Further, the base material 100 can be cut into an arbitrary shape. The substrate 100 can bond or adhere two objects to each other by using the permanent adhesive layer 200 and the removable adhesive layer 300 formed on the first surface and the second surface, There are no restrictions on the shape.

9, the first attached object is attached to the permanent adhesive layer (S300). At this time, the first attached object may be an object that is fixed to the differential tape and is not desorbed at a later time. The first attached object may be different depending on the use. The first attached object may be, for example, an object such as an air cell layer (500 in Fig. 7), a photograph, and a masking paper. However, the present invention is not limited thereto.

Referring again to Fig. 9, a rimmed adhesive layer is attached to the second attached object (S400).

At this time, the second attached object may be an object that is temporarily attached to the differential tape and is later detached. The second attachment object may be, for example, an object such as a window, a wall, and an outer wall of a vehicle. However, the present invention is not limited thereto. The rimmed adhesive layer 300 is free to be detached and attached, and there is no trace left at the time of detachment.

Although the steps of attaching the first attached object to the permanent adhesive layer 200 and attaching the rimmed adhesive layer 300 to the second attached object are sequentially shown in the drawing, They may also proceed in the opposite order.

Hereinafter, a method of using the differential tape according to some embodiments of the present invention will be described with reference to FIGS. 5 and 10. FIG. The portions of the above-described differential tape and the method of using the differential tape are duplicated or omitted.

10 is a flowchart for explaining a method of using a differential tape according to some embodiments of the present invention.

Referring to FIG. 10, a differential tape is provided (S100), and the differential tape is cut into a first shape (S200).

Subsequently, the first release liner is removed (S250).

Specifically, referring to FIG. 5, the first release liner 400a may be formed on the permanent adhesive layer 200. FIG. The first release liner 400a may be a film obtained by subjecting a film such as paper, polyethylene, polypropylene, or polyethylene terephthalate to a release treatment to improve the releasability with the permanent adhesive layer 200. The material used for the peeling treatment of the first release liner 400a of the present embodiment is not particularly limited, and for example, materials such as fluoro silicone, long-chain alkyl vinyl monomer polymer, and aminoalkyd resin can be used. The thickness T4a of the first release liner 400a is not particularly limited, but may be, for example, usually in the range of 25 mu m to 150 mu m.

As the first release liner 400a is removed, the surface of the permanent adhesive layer 200 can be exposed. The first attachment object may be attached to the exposed surface of the permanent adhesive layer 200 at a later time.

Referring again to Fig. 10, the first attached object is attached to the permanent adhesive layer (S300).

Subsequently, the second release liner is removed (S350).

Referring to Fig. 5, a second release liner 400b may be formed on the rimmed adhesive layer 300. Fig. The second release liner 400b may be a film obtained by subjecting a film such as paper, polyethylene, polypropylene, polyethylene terephthalate or the like to a release treatment for improving releasability with the permanent adhesive layer 200. The material used for the peeling treatment of the second release liner 400b of the present embodiment is not particularly limited, and for example, materials such as fluoro silicone, long-chain alkyl vinyl monomer polymer, and aminoalkyd resin can be used. That is, the second release liner 400b may include the same material as the first release liner 400a, but is not limited thereto. The thickness T4b of the second release liner 400b is not particularly limited, but may be in the range of usually 25 mu m to 150 mu m, for example.

As the second release liner 400b is removed, the surface of the rimmed adhesive layer 300 can be exposed. The second attachment object may be attached to the exposed surface of the rimmed adhesive layer 300 at a later time.

Referring again to Fig. 10, a rimmed adhesive layer is attached to the second attached object (S400).

In the drawing, a step (S250) of removing the first release liner (400a), a step (S300) of attaching the first attached object to the permanent adhesive layer (200), a step of removing the second release liner And attaching the rimmed adhesive layer 300 to the second attached object (S400). However, the above steps may be performed in the opposite order.
