FLAME-RETARDANT SELF-ADHESIVE COMPOSITION AND FLAME-RETARDANT SELF-ADHESIVE TAPE USING THE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a flame-retardant self-adhesive composition that has high flame retardancy compliant with UL94 standard while maintaining self-adhesive characteristics when processed into a tape form without using a halogen-based flame retardant etc., from a viewpoint of environmental protection.;SOLUTION: The flame-retardant self-adhesive composition contains (A) a (meth)acrylic ester polymer whose constituent monomer as a principal component is an acrylic or methacrylic ester monomer in which an ester bond of a 1-7C alkyl group is formed, (B) a phosphazene-based flame retardant, (C) a phosphoric ester-based flame retardant, (D) a crosslinking agent, and (E) a tackifier resin, wherein the total blending amount of the component (B) and the component (C) is in the range of 60-350 pts.mass based on 100 pts.mass of the component (A), and a blending ratio of the component (B) to the component (C) is 25:75 to 75:25 in a mass ratio.;COPYRIGHT: (C)2011,JPO&INPIT
