COMPOSITION FOR ACRYLIC PRESSURE-SENSITIVE ADHESIVE AND SURFACE FINISHING MATERIAL COMPRISING THE SAME

摘要

PURPOSE: An acrylic pressure-sensitive adhesive composition is provided to improve dispersibility of a flame retardant, adhesion property and flame retardant property by controlling a crosslinking structure of an acrylic copolymer. CONSTITUTION: An acrylic pressure-sensitive adhesive composition comprises an acrylic copolymer(A) and a flame retardant(B). The acrylic copolymer(A) comprises: (i) 50-90 parts by weight of an alkyl(meth)acrylic acid ester monomer with C2-14 alkyl group; (ii) 1-10 parts by weight of a crosslinkable functional group-containing monomer; (iii) 10-20 parts by weight of a methyl(meth)acrylate monomer; (iv) 10-20 parts by weight of vinyl acetate monomer; (v) 0.1-2 parts by weight of glycidyl(meth)acrylate; and (vi) 0.1-2 parts by weight of a crosslinking agent containing 5-15 alkylene oxide group and at least two acrylate group or vinyl group.
