Problems solved by technology

[0003] However, in recent years, office automation equipment, home appliances, etc. have a tendency to increase designs that often use curved surfaces or complex shapes. In the case of using the above-mentioned double-sided adhesive tape for the curved surface or complex shape parts, the curved surface adhesiveness (to the curved surface Followability, rebound resistance to bending members, etc.) or height difference followability is insufficient, resulting in defects such as peeling and falling of the decorative panel
In addition, in the case of decorative panels with a small adhesive area such as elongated shapes, the adhesiveness may be insufficient

preparation example Construction

[0067] In the production method of the bubble-containing adhesive, the method of mixing bubbles is not particularly limited, and known bubble mixing methods can be used. For example, as an example of the device, a device having a stator having many fine teeth on a disk having a through hole in the center and a rotor facing the toothed stator and having the same fine teeth on the disk as the stator can be cited. Wait. By introducing a compound mixed with air bubbles between the teeth of the stator and rotor of this device and rotating the rotor at a high speed, while introducing a gas component for forming air bubbles (bubble forming gas) through the through holes, thereby A bubble-containing adhesive in which the bubble-forming gas is finely dispersed and mixed can be obtained.

[0068] In addition, in order to suppress or prevent coalescence of air bubbles, it is preferable to continuously perform the steps from mixing of air bubbles to formation of an adhesive layer as a se...

Embodiment 1

[0109] Into a monomer mixture obtained by mixing 90 parts by weight of 2-ethylhexyl acrylate and 10 parts by weight of acrylic acid as a monomer component, was blended a photoresist with the trade name "Irgacyua 651" (manufactured by Chiba Specialty Chemical Co., Ltd.) After 0.05 parts by weight of a polymerization initiator and 0.05 parts by weight of a photopolymerization initiator with a trade name of "Irgakiyua 184" (manufactured by Chiba Specialty Chemicals Co., Ltd.), ultraviolet light was irradiated until the viscosity (BH viscometer, No. 5 rotor, 10 rpm, Measurement temperature: 30° C.) reaches about 15 Pa·s, and a partially polymerized composition (slurry) is prepared. To 100 parts by weight of the slurry, 0.04 parts by weight of a photopolymerization initiator, 0.1 parts by weight of 1,6-hexanediol diacrylate, 0.7 parts by weight of a fluorine-containing surfactant with a trade name of "Megafact F-477" (manufactured by DIC Corporation) and 0.02 parts by weight of car...

Abstract

The invention provides a double-faced pressure-sensitive adhesive tape for affixing decorative panels, characterized by having a pressure-sensitive adhesive layer containing bubbles and / or hollow microspheres. It is preferable that the pressure-sensitive adhesive layer be constituted of an acrylic pressure-sensitive adhesive, in particular, an acrylic pressure-sensitive adhesive curable with actinic energy rays. The double-faced pressure-sensitive adhesive tape for affixing decorative panels preferably has a toluene emission of 15 [mu]g / g or less. It is preferable that a surface of the adhesive tape have an L* (lightness) of 60-30. The double-faced pressure-sensitive adhesive tape for affixing decorative panels has excellent conformability to curved surfaces or surfaces having a difference in level, resistance to resilience, and adhesion. The adhesive tape can hence show excellent adhesive properties when a decorative panel is adhered to an adherend of a complicated shape having a curved surface or a difference in level and even when a slender decorative panel is adhered.

Description

technical field [0001] The present invention relates to a double-sided adhesive tape for fixing decorative panels. More specifically, the present invention relates to a double-sided pressure-sensitive adhesive tape for fixing a decorative board as a bubble-containing pressure-sensitive adhesive tape provided with a pressure-sensitive adhesive layer containing bubbles and / or hollow microspheres. Background technique [0002] Conventionally, in household electrical appliances, office automation equipment, furniture, kitchen materials, flooring materials, etc., a method of imparting design and decorative properties by attaching a decorative board to the surface of the product or the like has been used. When attaching such a decorative board, an adhesive tape (especially a double-sided adhesive tape) may be used from a viewpoint of simplicity (for example, refer patent document 1). [0003] However, in recent years, office automation equipment, home appliances, etc. have a tend...
