Pressure-sensitive adhesive composition and pressure-sensitive adhesive containing same

The invention provides a pressure-sensitive adhesive composition and a pressure-sensitive adhesive containing the same. The pressure-sensitive adhesive composition comprises acrylic resin containing acarboxylic acid functional group, wherein the weight percentage of the acrylic resin in the pressure-sensitive adhesive composition is 80-99wt%; and silica particles, wherein the surface of the silica particles contains an epoxy functional group, and the weight percentage of the silica particles in the pressure sensitive adhesive composition is between 2 and 10 wt%. The pressure-sensitive adhesive composition has high adhesive force, and the adhesive force of the pressure-sensitive adhesive tape prepared from the composition to different base materials can reach the peel strength of 0.9 kgf/inch or above. 本揭露提供一种感压胶组合物及包含该组合物的感压胶。该感压胶组合物，包括：压克力树脂，包含羧酸官能基，其中该压克力树脂于该感压胶组合物中的重量百分比介于80-99wt％；以及二氧化硅粒子，其表面包含环氧官能基，其中该二氧化硅粒子于该感压胶组合物中的重量百分比介于2-10wt％。本发明提供的感压胶组合物具有高粘着力，经由该组合物制备的成感压胶带对于不同基材的粘着力皆可达到0.9kgf/inch以上的剥离强度。
