The invention relates to a special structure film for a mirror seat of a rear-view mirror in an automobile. The structure film is prepared from the following raw materials in parts by weight: 20-100 parts of acrylonitrile-butadiene rubber, 0-70 parts of polysulfide rubber which is not cured fully, 5-40 parts of bisphenol A type epoxy resin, 10-60 parts of modified epoxy resin, 0.1-2.5 parts of cross-linking agent, 0.2-2.5 parts of softening agent, 3-20 parts of curing agent, 1-10 parts of accelerant, 20-100 parts of inorganic filler and 0.1-3.0 parts of silane coupling agent. The structure film disclosed by the invention has the advantages of good film-forming performance, good aging resistance, simple curing process, high strength of structural adhesive after curing, good toughness, excellent heat resistance and cold resistance and the like.
