Adhesion evaluation method : 20 m width from rubber / rubber adhesive composite
A sample of m is prepared and a peeling test is performed. When interfacial peeling occurred by this peeling test, it was evaluated as poor (x) even if the adhesive strength was high. On the other hand, when no interfacial peeling occurred, a sheet having a thickness of about 0.5 mm was cut out around the adhesive interface of the adhesive composite using a razor,
A peeling test was performed with a razor scratched in the vicinity of the adhesive interface of the sheet, and a case where any one of the rubber sheets adhered so strongly as to cause cohesive failure inside was evaluated as having good adhesiveness (O).
