Abstract

Lámina adhesiva con canales de aireación de múltiples fases, incluyendo la lámina adhesiva una película de base y una capa adhesiva sensible a la presión, en la que la capa adhesiva tiene dibujos superficiales formados mediante la transferencia de partes convexo-cóncavas sobre una superficie de desprendimiento de un forro de desprendimiento, formándose los dibujos superficiales por al menos dos clases de canales conectados entre sí, incluyendo las al menos dos clases de canales, canales de primera fase con una altura relativamente menor y canales de segunda fase con una altura relativamente mayor, y los canales de primera fase se disponen con un intervalo menor y los canales de segunda fase se disponen con un intervalo mayor, en la que los canales de primera fase tienen una altura de 3 μm a 10 μm y una anchura de 10 μm a 30 μm, y los canales de segunda fase tienen una altura de 10 μm a 20 μm y una anchura de 30 μm a 60 μm, y en la que los canales de segunda fase se disponen con un intervalo de 2 mm a 4 mm y las longitudes de los trayectos de aireación de los canales de primera fase se limitan al intervalo dimensional, de modo que los canales de primera fase proporcionan canales de aireación antes de desaparecer una vez unida la lámina adhesiva a una superficie objetivo, de modo que puede aumentarse el área de adhesión a la superficie objetivo a medida que los canales de primera fase van desapareciendo, y los canales de segunda fase proporcionan canales de aireación incluso después de que los canales de primera fase hayan desaparecido.Adhesive sheet with multi-phase aeration channels, including the adhesive sheet a base film and a pressure sensitive adhesive layer, in which the adhesive layer has surface drawings formed by transferring convex-concave portions onto a detachment surface of a detachment liner, the surface drawings being formed by at least two kinds of channels connected to each other, including at least two kinds of channels, first phase channels with a relatively smaller height and second phase channels with a relatively greater height, and the first phase channels are arranged with a smaller interval and the second phase channels are arranged with a larger interval, in which the first phase channels have a height of 3 μm to 10 μm and a width of 10 μm to 30 μm, and the second phase channels have a height of 10 μm to 20 μm and a width of 30 μm to 60 μm, and in which the second phase channels are distributed set with a range of 2 mm to 4 mm and the lengths of the aeration paths of the first phase channels are limited to the dimensional range, so that the first phase channels provide aeration channels before disappearing once the sheet is attached adhesive to a target surface, so that the area of adhesion to the target surface can be increased as the first phase channels disappear, and the second phase channels provide aeration channels even after the first phase channels have missing.

Ejemplo comparativo 6 Comparative Example 6

También en este ejemplo comparativo se formaron canales bajos (L) y canales altos (H) tal como se muestra en la tabla 2. Los canales tuvieron una altura relativamente mayor con respecto al ejemplo. Hubo un pequeño deterioro de la fuerza adhesiva, pero se encontró que el estado de la superficie de la película fue muy malo. Also in this comparative example, low channels (L) and high channels (H) were formed as shown in table 2. The channels had a relatively higher height with respect to the example. There was a slight deterioration of the adhesive force, but it was found that the condition of the film surface was very bad.

A partir de estos ejemplos comparativos mostrados en la 2 y otros experimentos relacionados se encontró que no puede evacuarse eficazmente el aire pero que se mantuvo la fuerza adhesiva cuando la altura de los canales no es mayor de 10 mm. Además, para impedir que los dibujos provocados por partes convexo-cóncavas sobre una superficie adhesiva se reconozcan a simple vista en una superficie frontal de una lámina después de unir la lámina, la altura de los canales preferiblemente no es mayor de 20 mm. From these comparative examples shown in 2 and other related experiments it was found that the air cannot be effectively evacuated but that the adhesive force was maintained when the height of the channels is not more than 10 mm. In addition, to prevent the drawings caused by convex-concave parts on an adhesive surface from being visible to the naked eye on a front surface of a sheet after joining the sheet, the height of the channels is preferably not more than 20 mm.

En el ejemplo se formaron dos clases de canales basándose en los resultados de observación anteriores. Si la separación entre dibujos es de 2 a 4 mm, existe la desventaja de que la fuerza adhesiva es baja durante un corto In the example, two kinds of channels were formed based on the previous observation results. If the separation between drawings is 2 to 4 mm, there is a disadvantage that the adhesive force is low during a short

Aplicabilidad industrial Industrial applicability

Según la presente invención se forman canales de primera fase con una altura menor y canales de segunda fase con una altura mayor de modo que estén conectados entre sí, de modo que los canales de primera fase pueden servir como canales de aireación con una longitud más corta durante un corto periodo de tiempo y después desaparecer para dar lugar a un área de contacto más amplia, mientras que los canales de segunda fase pueden servir como canales de aireación durante un periodo de tiempo prolongado, dando como resultado una mejora en la According to the present invention, first phase channels with a lower height and second phase channels with a higher height are formed so that they are connected to each other, so that the first phase channels can serve as aeration channels with a shorter length for a short period of time and then disappear to give rise to a wider contact area, while the second phase channels can serve as aeration channels for a prolonged period of time, resulting in an improvement in

65 aplicación de una lámina adhesiva, y evitándose que emerjan dibujos sobre una superficie frontal de la lámina desde los canales para mejorar el aspecto. 65 application of an adhesive sheet, and preventing drawings from emerging on a front surface of the sheet from the channels to improve the appearance.
