Title (EN) DOUBLE-SIDED TAPE USING POLYMER-BASED BEAD AS SHOCK ABSORBER FOR IMPACT ABSORPTION
(FR) RUBAN DOUBLE FACE UTILISANT UNE PERLE À BASE DE POLYMÈRE, EN TANT QU'ABSORBEUR DE CHOCS DESTINÉ À L'ABSORPTION D'IMPACTS
(KO) 폴리머계 비드를 충격 흡수재로 이용하는 충격 흡수용 양면 테이프
Abstract: front page image
(EN)The present invention relates to a double-sided tape for impact absorption, which is used for stably attaching optical equipment, such as a protective panel, a glass, or camera lens, in connection with manufacturing a small personal electronic device including a display means for providing information or a photographing means (camera) for inputting information. According to the present invention, a first adhesive layer (11), an impact absorbing layer (12), a PET film or black PET film (13), a second adhesive layer (14), and a release paper (15) are laminated in that order from the top to form a double-sided tape (10) having a total thickness of 0.1 to 1 mm, wherein the impact absorbing layer (12) is made by mixing an acryl-based resin (121) and a polymer-based bead (122). The double-sided tape of the present invention comprising the spherical polymer-based bead as an impact absorber not only can be simply manufactured at a low cost but also has an effect of exhibiting an excellent impact absorbing ability in comparison with a double-sided tape made of foamed acrylic foam or PE foam.
(FR)La présente invention concerne un ruban double face destiné à l'absorption d'impacts, qui est utilisé pour fixer d'une manière stable un équipement optique, tel qu'un panneau protecteur, un verre ou une lentille d'appareil photographique, en liaison avec la fabrication d'un petit dispositif électronique personnel, comprenant un moyen d'affichage destiné à donner des informations, ou un moyen de photographie (appareil photographique), destiné à saisir des informations. Selon la présente invention, une première couche adhésive (11), une couche (12) absorbant les impacts, un film de PET ou un film de PET noir (13), une seconde couche adhésive (14) et un papier antiadhésif (15) sont contrecollés dans cet ordre, à partir du haut, pour former un ruban double face (10) présentant une épaisseur totale de 0,1 à 1 mm, la couche (12) absorbant les impacts étant fabriquée par mélange d'une résine (121) à base acrylique et d'une perle (122) à base de polymère. Le ruban double face de la présente invention, comprenant la perle sphérique à base de polymère, servant d'absorbeur d'impacts, non seulement peut être fabriqué d'une manière simple à faible coût, mais encore a pour effet de présenter une excellente capacité d'absorption des impacts, par comparaison avec un ruban double face constitué de mousse acrylique expansée ou de mousse de PE.
(KO)본 발명은 정보 제공용 디스플레이 수단이나 정보 입력용 촬영수단(camera) 등을 구비하는 개인용 소형 전자제품을 제조함에 있어 보호패널, 글라스(glass)나 카메라 렌즈 등과 같은 광학용 기자재를 안정적으로 부착하여 주기 위한 용도로 사용되는 충격 흡수용 양면 테이프에 관한 것이다. 본 발명은 위로부터 제1 점착층(11), 충격 흡수층(12), PET 필름 또는 흑색 PET 필름(13), 제2 점착층(14), 이형지(15)의 순서를 이루도록 적층하여 전체 두께 0.1 ~ 1㎜의 두께로 양면 테이프(10)를 구성하고, 상기 충격 흡수층(12)은 아크릴계 수지(121)와 폴리머계 비드(122)를 혼합하여 조성한 것이다. 본 발명은 구상체의 폴리머계 비드를 충격 흡수재로 하여 양면 테이프를 구성한 것으로, 양면 테이프의 제조가 간단하고 제조비용이 저렴하게 할 수 있을 뿐만 아니라 발포된 아크릴 폼, PE 폼으로 제조된 양면 테이프에 비해 우수한 충격 흡수능력을 발휘하는 등의 효과가 있는 것이다.
