Title (EN) ADHESIVE TAPE FOR CAR
(FR) BANDE ADHÉSIVE POUR VOITURE
(KO) 자동차용 점착테이프
Abstract: front page image
(EN)The present invention provides a pressure sensitive adhesive tape comprising: an acrylic foam layer; and rubber-based adhesive layers which are formed on both sides of said acrylic foam layer, wherein the content of gel in said rubber-based adhesive layers is 40% or more. Furthermore, in order to accomplish the object of the present invention, a method for manufacturing a pressure sensitive adhesive layer is provided, and the method comprises the steps of: manufacturing an acrylic foam layer; and forming rubber-based adhesive layers on one side or both sides of said acrylic foam layer, wherein said step of forming the rubber-based adhesive layers comprises the steps of: manufacturing a styrene block copolymer; forming rubber-based adhesive layers by adding an adhesive additive and a plasticizer to said styrene block copolymer; and setting the content of gel in said rubber-based adhesive layers to 40% or more.
(FR)La présente invention concerne une bande adhésive sensible à la pression comprenant : une couche de mousse acrylique ; et des couches adhésives à base de caoutchouc formées des deux côtés de la couche de mousse acrylique, la teneur en gel dans lesdites couches adhésives à base de caoutchouc étant supérieure ou égale à 40 %. L'invention concerne également un procédé de fabrication d'une couche adhésive sensible à la pression, le procédé comprenant les étapes suivantes : la fabrication d'une couche de mousse acrylique ; et la formation de couches adhésives à base de caoutchouc d'un côté ou des deux côtés de ladite couche de mousse acrylique. Ladite étape de formation des couches adhésives à base de caoutchouc comprend les étapes suivantes : la fabrication d'un copolymère styrénique séquencé ; la formation de couches adhésives à base de caoutchouc par l'ajout d'un additif adhésif et d'un plastifiant audit copolymère styrénique séquencé ; et l'ajustement de la teneur en gel dans lesdites couches adhésives à base de caoutchouc à 40 % ou plus.
