Abstract

Disclosed is a flame resistant adhesive composition having superior flame resistance as well as superior initial tackiness and stability of tackiness over time, and also disclosed are a flame resistant adhesive tape and a flame resistant adhesive sheet using that flame resistant adhesive composition. The flame resistant adhesive composition contains a (meth)acrylate ester copolymer for component (A) and a flame retardant for component (B). The flame retardant, which is component (B), contains an aromatic phosphate ester, and the component (B) content is 70 - 200 parts by weight to 100 parts by weight of component (A). Components (a) - (c) are included as monomer components during the copolymerization of component (A). (a) C1-12 (meth)acrylate alkyl ester: 100 parts by weight (b) Vinyl compound containing carboxyl group: 0 parts by weight or 0 - 1 parts by weight (not including 0 parts by weight) (c) Vinyl compound containing nitrogen: 1 - 70 parts by weight.

Description

technical field [0001] The present invention relates to a flame-retardant adhesive composition, a flame-retardant adhesive tape, and a flame-retardant adhesive sheet. In particular, it relates to a flame-retardant adhesive composition, a flame-retardant adhesive tape, and a flame-retardant adhesive sheet that are excellent in flame retardancy and excellent in initial adhesiveness and stability over time of adhesiveness. Background technique [0002] Conventionally, electrical insulating tapes and the like used in electronic components and the like have been required to have high flame retardancy, such as VTM-0 to 2 grades in the UL94 standard, as a standard of the flame retardancy. [0003] Therefore, in order to improve the flame retardancy of an adhesive composition in an electrical insulating tape or the like, a method of including various flame retardants in the adhesive composition is generally employed. In addition, as the flame retardant, common flame retardants incl...
