Adhesion test method of rubber and adhesion test system of rubber

摘要

To provide an adhesion test method of rubber taking also the change in real contact area into account.SOLUTION: The test method includes: steps (ST2 and ST4) of pressing a rubber test member W onto a prescribed road surface 12 for a predetermined contact time and then peeling it, and measuring a gravitation acting during the peeling operation a plurality of times while the contact time is varied; and a step (ST5) of calculating the relational expression between the adhesive force corresponding to the gravitation and the contact time, on the basis of a plurality of measurement results.SELECTED DRAWING: Figure 2
