ACRYLIC ADHESIVE COMPOSITION AND ADHESIVE COMMODITIES CONTAINING THE SAME

摘要

An acrylic adhesive composition easy to be attached or detached after use, and an adhesive product containing the composition are provided to improve initial adhesive strength and adhesion maintenance. An acrylic adhesive composition comprises 100 parts by weight of an acrylic adhesive resin; 5-30 parts by weight of a petroleum-based tackifier; and 15-40 parts by weight of a thermal expandable filler. Preferably the acrylic adhesive resin is an aqueous acrylic adhesive resin or an oily acrylic adhesive resin; the petroleum-based tackifier is a polymer polymerized from a vinyl monomer containing a C3-C12 (meth)acryloyl group and has a viscosity of 1,000-80,000 and a weight average molecular weight of 500-50,000; and the filler has an average particle size of 6-32 micrometers.
