Abstract
(EN)
The present invention provides an elastic pressure-sensitive adhesive layer, a pressure-sensitive adhesive tape, and a method for preparing the pressure-sensitive adhesive tape. The elastic pressure-sensitive adhesive layer and the elastic pressure-sensitive adhesive tape provided by the present invention utilize the technique of reacting the structure of a main material with water to generate a gas and expand the volume of the material, to provide elasticity to the adhesive layer and adhesive tape. The present invention overcomes the limitations of traditional foam tapes, and has good cushioning and compressibility without the need to use foam as a base material, and is superior to foam tapes in terms of die-cutting stability. Furthermore, in the present invention, the thickness, viscosity, and compressibility of the elastic pressure-sensitive adhesive layer and the elastic pressure-sensitive adhesive tape can be customized according to actual application requirements, and have high flexibility in practice.

La présente invention concerne une couche adhésive autocollante élastique, une bande adhésive autocollante, et un procédé de préparation de la bande adhésive autocollante. La couche adhésive autocollante élastique et la bande adhésive autocollante élastique fournies par la présente invention utilisent la technique de réaction de la structure d'un matériau principal avec de l'eau pour générer un gaz et dilater le volume du matériau, afin de conférer une élasticité à la couche adhésive et à la bande adhésive. La présente invention surmonte les limitations des bandes de mousse conventionnelles, et présente un amortissement et une compressibilité satisfaisants sans la nécessité d'utiliser une mousse en tant que matériau de base, et est supérieure aux bandes de mousse en termes de stabilité au découpage à l'emporte-pièce. En outre, dans la présente invention, l'épaisseur, la viscosité et la compressibilité de la couche adhésive autocollante élastique et de la bande adhésive autocollante élastique peuvent être adaptées aux besoins d'applications réelles, et ont une flexibilité élevée dans la pratique.
