Abstract
A differential tape is provided. Wherein the differential tape comprises a tape including a first surface and a second surface opposed to each other, a permanent adhesive layer formed on the first surface and having a first adhesive strength and a second adhesive strength layer formed on the second surface, And a removable adhesive layer having a second adhesive strength smaller than that of the second adhesive layer and capable of being attached to and detached from the adhesive object several times.
Description
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.
A problem to be solved by the present invention is to provide a differential tape in which a permanent adhesive layer is formed on one side and a rimbeing adhesive layer is formed on the other side, and the usability of both sides is different.
Another problem to be solved by the present invention is to provide a method of using a differential tape in which a permanent adhesive layer is formed on one side and a rimmed adhesive layer is formed on the other side,
The problems to be solved by the present invention are not limited to the above-mentioned problems, and other matters not mentioned can be clearly understood by those skilled in the art from the following description.
According to some embodiments of the present invention, there is provided a differential tape comprising: a tape including a first surface and a second surface opposed to each other; a permanent adhesive layer formed on the first surface and having a first adhesive strength; And a ridproof adhesive layer formed on the second surface, the ridproof adhesive layer having a second bonding strength smaller than the first bonding strength and capable of being attached to and detached from the bonding object several times.
Here, the release liner may further include a release liner which is attached on the removable pressure sensitive adhesive layer and is removed before being adhered to the pressure sensitive adhesive object to expose the removable pressure sensitive adhesive layer.
The permanent adhesive layer and the removable adhesive layer may contain different materials.
The permanent adhesive layer includes vinyl acetate and may include the methyl acrylate.
The tape may comprise any one of a nonwoven tape, a paper tape, a cloth tape, a tear film tape, a bark tape, a PE foam tape, a urethane foam tape and a PE film tape.
The airbag module may further include an air cell layer including an air cell coupled to the permanent adhesive layer and containing air therein.
The thickness of the permanent adhesive layer may be thicker than the thickness of the removable adhesive layer.
The tape can be cut to any shape.
The permanent pressure-sensitive adhesive and the rigid pressure-sensitive adhesive may be a solvent-type pressure-sensitive adhesive.
The tape may be transparent.
According to another aspect of the present invention, there is provided a method of using a differential tape, including: providing a substrate including a first surface and a second surface opposite to each other; And a rimmed adhesive layer formed on the second surface and having a second bonding strength lower than the first bonding strength and capable of being attached to and detached from the bonding object several times, the method comprising: Attaching the differential tape to the first attached object so that the permanent adhesive layer is in contact with the first attached object, and attaching the removable adhesive layer to the second attached object.
The differential tape includes a first release liner adhered on the permanent adhesive layer and a second release liner adhered on the rimmed adhesive layer, and before the differential tape is attached to the first attachment object, Removing the first release liner to expose the permanent adhesive layer and removing the second release liner prior to attaching the removable adhesive layer to the second attached object to expose the removable adhesive layer have.
According to the differential tape according to some embodiments of the present invention, a pressure-sensitive adhesive that strongly fastens a tape to an object with strong adhesive force is used on one side, and a relatively adhesive force By using this weak adhesive agent, the object can be adhered to another object such as a wall temporarily.
As a result, it is possible to give an adhesive property to an object having no original adhesive property, and through such adhesive property, fixation of an object can be easily achieved. Furthermore, it is easy to modify the position of such an object.
In addition, according to the differential tape according to some embodiments of the present invention, by including a tape that can be easily cut into a desired size and a desired shape, a desired portion of an object to be attached can be easily .
In addition, according to the differential tape according to some embodiments of the present invention, the differential tape can be used as a heat insulating material that can be easily attached to and detached from a window in combination with an air cell layer on a differential tape.
