Abstract[English]
The present invention provides a styrene-acrylic-emulsion-containing aqueous pressure-sensitive adhesive composition, an adhesive tape, and preparation methods therefor. The styrene-acrylic-emulsion-containing aqueous pressure- sensitive adhesive composition comprises an aqueous adhesive matrix and a styrene-acrylic emulsion, wherein the aqueous adhesive matrix is an aqueous acrylic adhesive matrix or a tackifying resin-modified aqueous acrylic adhesive matrix, and the styrene-acrylic emulsion comprises a styrene-acrylate copolymer. An adhesive tape with an adhesive layer prepared from the aqueous pressure- sensitive adhesive composition has a suitable peeling property and a significantly improved cohesion.[French]
La présente invention concerne une composition adhésive aqueuse sensible à la pression contenant une émulsion styrène-acrylique, une bande adhésive et leurs procédés de préparation. La composition adhésive aqueuse sensible à la pression contenant une émulsion styrène-acrylique comprend une matrice adhésive aqueuse et une émulsion styrène-acrylique, la matrice adhésive aqueuse étant une matrice adhésive acrylique aqueuse ou une matrice adhésive acrylique aqueuse modifiée par une résine à pouvoir collant, et l'émulsion styrène-acrylique comprenant un copolymère d'acrylates de styrène. Une bande adhésive comprenant une couche adhésive préparée à partir de la composition adhésive aqueuse sensible à la pression a une propriété de pelage appropriée et une cohésion significativement améliorée.
