するものがある。Conventional double-sided adhesive tapes for rubbing cloth are:
One substrate and two substrates have the same adhesive strength on one surface and two
The adhesive strength of the surface is changed, the rubbing cloth is adhered with the stronger adhesive strength, and the adhesive strength of the weaker adhesive strength is adhered to the rubbing roller. Some are formed thicker than the adhesive layer on the roller side.

接着強度に差ができる。[0007] The base material has an appropriate thickness to the tape, and has a property of easily securing an effective adhesive area at the time of pressure bonding (generally, a flexible base material is used), a property of easily peeling, and a property of transparency (general). (A plastic substrate having a strong substrate) is used, and the adhesive strength can be varied depending on the type of the substrate.

法である。In a rubbing step in a liquid crystal panel manufacturing process,
There is an operation of attaching a rubbing cloth to a rubbing roller. The mainstream of the attaching method is an attaching method using a double-sided adhesive tape.

を固有している。The structure of the rubbing cloth as one of the adherends is as follows.
Woven yarn such as rayon, nylon, cotton, etc. is woven into W-shape or V-shape into a base fabric composed of woven yarn such as polyester for warp and weft, and weaving the warp and weft in a lattice. A back coating of a resin agent is formed from the back surface. For this reason, the adhesive surface of the rubbing cloth inherently has irregularities having a height h of about 0.1 to 0.5 mm caused by weaving of the bristle.
【００１０】他方の被着体であるラビングローラの接着
面は、精密な機械加工で製造されているので非常に滑ら
かな面である。[0010] The bonding surface of the rubbing roller, which is the other adherend, is a very smooth surface because it is manufactured by precision machining.

替え時にラビングローラ表面から手作業で容易に剥離
し、接着剤の残存が少ない作業性の良いことである。The characteristics required of a double-sided adhesive tape for attaching a rubbing cloth are that the adhesive strength is required so that the number of rubbing treatments can be performed in accordance with a predetermined production number, and that the rubbing roller is manually replaced from the surface of the rubbing roller when replacing the rubbing cloth. It is easy to peel off, and has good workability with little adhesive remaining.

変な労力と時間を要する問題がある。For example, in the case of a double-sided adhesive tape in which the base material is a non-woven fabric having flexibility and high adhesive strength and formed on one and two sides with an acrylic pressure-sensitive adhesive, the pressure-sensitive adhesive is often used as a base material. Impregnated into the material and adhere to the substrate with the thickness and softness of the substrate
It absorbs irregularities, so it is easy to secure an effective bonding area and the bonding strength is moderate, but it is very difficult to peel off once again (removability) once it is applied due to its poor base strength and base stretchability. . This double-sided adhesive tape is suitable for bonding to irregularities such as the rubbing cloth bonding surface , and has an adhesive strength that enables the number of rubbing treatments according to the specific production number. There is a problem that requires a lot of labor and time.

ラビング布の継ぎ目部から布剥がれを起こし、品質不良
となっている。The base material is a plastic base material such as a polyester film or a polypropylene film,
A double-sided adhesive tape formed of an acrylic pressure-sensitive adhesive has inflexibility and poor cushioning properties, so it is difficult to secure an effective area for bonding to uneven surfaces. The adhesive strength to the body is hardly obtained, and the fabric is peeled off from the seam portion of the rubbing cloth until the predetermined number of rubbing treatments is reached, resulting in poor quality.

発生する。[0015] On the other hand, since it has the feature that the substrate strength and the substrate stretchability are excellent, the removability from the rubbing roller is satisfied. Therefore, there is also a double-sided adhesive tape in which the adhesive strength on the rubbing cloth side is made stronger than the adhesive strength on the rubbing roller side to secure the adhesive strength on the rubbing cloth side and to simultaneously obtain removability on the rubbing roller side. However, since the plastic substrate itself is inferior in flexibility, the rubbing cloth cannot be provided with an adhesive strength against the unevenness of the rubbing cloth bonding surface, and the rubbing cloth peels off as described above.

ビング処理回数を達成することが困難である。From the above, in the conventional double-sided adhesive tape configuration, the adhesion between the adherend having the uneven surface and the smooth adherend can provide sufficient adhesive strength to the uneven surface, and the tape can be peeled off again. It is difficult to simultaneously satisfy satisfactory characteristics and achieve a predetermined number of rubbing treatments.
【００１７】本発明はかかる点に鑑み、上記問題点が生
じない接着両面テープを提供することを目的とする。In view of the above, an object of the present invention is to provide a double-sided adhesive tape which does not cause the above-mentioned problems.

る。In order to solve the above-mentioned problems, a first base material having flexibility, a second base material having stretchability, and three adhesive layers are provided. A first base material having flexibility is sandwiched between the second adhesive layers, and a second base material having extensibility is sandwiched between the second adhesive layer and the third adhesive layer, and are combined into a laminate. A means having the above configuration is used.

Using the combined double-sided adhesive tape for applying a rubbing cloth, the double-sided adhesive tape side formed of a nonwoven fabric substrate is attached to the rubbing cloth side, and the double-sided adhesive tape side formed of a plastic base material is attached to the rubbing roller side.

ような柔軟性はない。The surface of the rubbing cloth bonded surface, which is one of the adherends, has irregularities of about 0.1 to 0.5 mm. Further, the rubbing cloth is a woven fabric, does not have planar accuracy as in the case of machining, and has unevenness in height. In addition, since it is coated with a resin agent for the purpose of preventing the rubbing cloth from coming off and imparting the strength of the base cloth, it is hard and does not have the flexibility of a normal cloth.

に大きな違いが生じる。In order to secure the adhesive strength of such an uneven surface, it is important how large an effective adhesive area can be obtained. In other words, the contact between the adhesive layer of the double-sided adhesive tape and the rubbing cloth bonding surface is not a surface contact but a collection of point contacts. It is necessary to obtain a high anchoring effect of bonding by making the adhesive layer bite more during the bonding. Since the base material of the double-sided adhesive tape adds a function to make it easy to secure the effective bonding area during pressure bonding, the anchoring effect of bonding differs depending on the material properties of the base material, and there is a large difference in bonding strength and removability. .

容易に考えられる。However, the height variation of the unevenness is absorbed,
In order to make the double-sided adhesive tape deeply bite the convex part with the applied pressure, use a nonwoven fabric, Japanese paper, or a base material made of foam that has more flexibility than increasing the adhesive strength of the double-sided adhesive tape. By digging the protrusions into the base material, the adhesive layer penetrates deeply between the protrusions and increases the anchoring effect of bonding, so it is easy to think that adhesive strength to the uneven surface can be obtained. Can be

する問題が生じる。On the other hand, the rubbing roller, which is the other adherend, is manufactured by precise mechanical cutting, so that the surface roughness is low.
A certain degree there. Assuming the surface roughness of the machined object as a collection of countless low V-grooves, the double-sided adhesive tape with flexibility cuts into countless V-grooves, resulting in a higher anchoring effect of bonding, Obtain stronger adhesive strength. Since the rubbing roller is recycled, the rubbing cloth is replaced.
At this time, the removability of the double-sided adhesive tape largely depends on the workability of cloth replacement. When a flexible substrate is used, when peeled from the rubbing roller, the peeling adhesive strength is stronger than the tensile strength of the substrate, so the substrate is broken in the middle and there is no continuity in re-peeling, Problems that require a lot of effort and time.

つきも吸収し難くなり接着有効面積が大きくとれず、凹
凸に対する所定の要求される接着強度が得られない。In order to obtain the removability of the double-sided adhesive tape, a plastic substrate such as polypropylene, polyester, vinyl chloride or the like which has a substrate strength and an extensibility that can withstand the peeling adhesive strength is suitable. However, a plastic substrate having high strength and stretchability has a disadvantage that flexibility is inferior.On the other hand, the repulsion of the substrate acts strongly against the pressing force to be adhered, and the convex portion is deep in the substrate. Since it is difficult to bite, the thickness of the adhesive layer is only about 30 to 40 μm, and it is difficult to absorb the unevenness in height of the unevenness, so that a large effective bonding area cannot be obtained, and a predetermined required adhesive strength for unevenness cannot be obtained.

れる特性を満足することができる。Therefore, the flexible base material is used as the first base material, the stretchable base material is used as the second base material, and the first base material and the second base material are bonded with the second adhesive layer. A base material that has been combined into a laminate is formed. Then, a first adhesive layer is formed on the surface of the first base material, and a third adhesive layer is formed on the surface of the second base material. By bonding an adherend having a surface, and by bonding an adherend having a smooth surface on the third adhesive layer side to the second substrate having a small anchoring effect and a strong substrate strength, Adhesive strength and removability on a smooth surface can be simultaneously obtained, and the required properties can be satisfied.

得る。The rubbing cloth having irregularities is well impregnated with an adhesive and is held and held by a double-sided adhesive tape formed of a flexible nonwoven base material having a cushioning property.
Since it is fixed, a sufficient bonding effective area is secured, and a suitable bonding strength is obtained. On the other hand, a rubbing roller having a smooth surface is a plastic base material having a thin base material and a poor cushioning property, and a double-sided adhesive tape formed with an adhesive layer capable of sufficiently obtaining an adhesive strength with a smooth surface, Due to the strength of the plastic base material and the stretchability of the base material, a function with good removability satisfying the adhesive strength with the rubbing roller is obtained.
