Description
また、発泡層を表面に気泡が露出されて吸着力を発揮する吸着孔を有するものとすれば、その吸着孔の吸着力を利用できる分、粘着性樹脂塗工量を少なくして糊残りを極力抑えつつ、吸着貼り付け強度を高めることができる。さらに、粘着性樹脂を発泡層の表面及び／又は吸着孔の壁面に浸透塗布すれば、吸着孔を塞がないので、その吸着力を損なうことがなく、粘着性樹脂によって粘着性能を高める分、吸着貼り付け強度を高めることができる。また、本発明は、上記の粘着シートの発泡層の表面に塗布する粘着性樹脂又はその粘着性樹脂の希釈液を提供する。
また、本発明による粘着シートは、発泡体を形成する発泡樹脂と粘着性を有する粘着樹脂とが混合した発泡層を有する。
ある実施形態において、前記発泡層の表面に、前記粘着樹脂と同系素材である同系樹脂が付着し得る。
ある実施形態において、前記発泡層の表面に、吸着力を有する複数の表面気泡を有し、前記複数の表面気泡の少なくとも一部には、前記同系樹脂が付着し得る。
ある実施形態において、前記発泡層の内部には、複数の内部気泡を有し、前記複数の内部気泡の少なくとも一部には、前記同系樹脂が浸透し得る。
ある実施形態において、前記粘着樹脂は、アクリル系樹脂であり、前記同系樹脂は、水溶性アクリル系樹脂であり得る。
また、本発明による粘着シート製造方法は、発泡体が形成される被発泡樹脂に発泡剤と粘着性を有する粘着樹脂とを加える工程と、前記被発泡樹脂を発泡することで、発泡体を形成する発泡樹脂と前記粘着樹脂とが混合した発泡層を形成する工程とを包含する。
In addition, if the foam layer has an adsorption hole that exposes bubbles on the surface and exerts an adsorption force, the adhesive resin can be used to reduce the amount of adhesive resin applied and reduce the adhesive residue. While suppressing as much as possible, the adhering and sticking strength can be increased. Furthermore, if the adhesive resin is osmotically applied to the surface of the foam layer and / or the wall of the adsorption hole, the adsorption hole is not blocked, so that the adsorption force is not impaired, and the adhesion performance is increased by the adhesive resin. Adsorption adhesion strength can be increased. Moreover, this invention provides the adhesive resin applied to the surface of the foaming layer of said adhesive sheet, or the dilution liquid of the adhesive resin.
The pressure-sensitive adhesive sheet according to the present invention has a foamed layer in which a foamed resin forming a foam and a pressure-sensitive adhesive resin are mixed.
In one embodiment, a similar resin that is the same material as the adhesive resin may adhere to the surface of the foam layer.
In one embodiment, the surface of the foam layer has a plurality of surface bubbles having an adsorptive power, and the similar resin may adhere to at least some of the plurality of surface bubbles.
In one embodiment, the foam layer has a plurality of internal bubbles, and the similar resin can permeate into at least a part of the plurality of internal bubbles.
In one embodiment, the adhesive resin may be an acrylic resin, and the similar resin may be a water-soluble acrylic resin.
Moreover, the pressure-sensitive adhesive sheet manufacturing method according to the present invention includes a step of adding a foaming agent and a pressure-sensitive adhesive resin to a foamed resin in which a foam is formed, and foaming the foamed resin to form a foam. Forming a foamed layer in which the foamed resin and the adhesive resin are mixed.
