preparation example 1

[0094]

[0095] By adding 100 mass parts of styrene-butadiene block copolymer S (a mixture of triblock copolymer and diblock copolymer) with a weight average molecular weight of 300,000. With respect to the total amount of the mixture, the two The proportion that block copolymer accounts for is 50 mass %.In the whole of described styrene-butadiene block copolymer, the mass proportion that polystyrene unit accounts for is 30 mass %, polybutadiene unit accounts for 70% by mass) and 100 parts by mass of terpene phenolic tackifying resin (softening point 115° C., molecular weight 1000) are dissolved in toluene to obtain the adhesive composition (a- 1).

preparation example 2

[0097]

[0098]The same method as in Preparation Example 1 was used to obtain an adhesive Adhesive composition (a-2).

[0099]

Embodiment 1

[0101] Using a rod-shaped metal applicator (applicator), 10 parts by mass of F-36D (Matsumoto Yushi Pharmaceutical Co., Ltd. Coated on both sides of high-grade paper in a way that the thickness after drying is 90 μm and coated with polyethylene Layer, and on the surface of a release paper with a thickness of 130 μm having a silicone-based mold release treatment agent layer on one side of the polyethylene layer, dry it for 10 minutes with a dryer set at 65° C., thereby producing an expansive adhesive. Adhesive layer (A-1). Laminate the expandable adhesive layer (A-1) on a release paper different from the above-mentioned release paper, use a 2 kg hand roller (hand roller) to perform a reciprocating motion on the upper surface of the sticker, Thus, an adhesive tape including the expandable adhesive layer (A-1) was obtained.

[0102] Next, the adhesive composition (a-1) was coated with a polyethylene layer on both sides of the high-grade paper so that the thickness after drying ...

Abstract

The purpose of the present invention is to provide an adhesive tape which can be sufficiently adhered and fixed even when a small load is exerted on the adhesive tape. The present invention relates toan adhesive tape that has at least one expandable adhesive layer (A) and is characterized in that the adhesive tape is disposed between at least two adherends and adheres when the expandable adhesivelayer (A) is expanded by stimulating the adhesive tape while exerting a load of 50 N / cm<2> or less thereon through one or both of the adherends contacting the adhesive tape.

Description

technical field [0001] The present invention relates to an adhesive tape, which is an adhesive tape having at least one expandable adhesive layer (A), the adhesive tape is arranged between two or more adherends, and the The adherend on one side or both sides of the adhesive tape is applied to the adhesive tape at 50N / cm 2 Simultaneously with the following load, a stimulus is applied to expand the expandable adhesive layer (A) to perform adhesion. Background technique [0002] Adhesive tapes are generally suitably used for fixing one adherend to another adherend, and are widely used, for example, in the production of various products such as automotive components and electrical equipment. [0003] When the adhesive tape is used to fix two or more adherends, the adhesive tape needs to be arranged between two or more adherends, and the adhesive tape contacts one or both sides of the adherends. Adhesives apply a sufficient load to the unit area of ​​the adhesive tape to make i...
