The present invention relates to a method for testing dynamic adhesion of rubber and a rubber rolled substance capable of evaluating an adhesive force test in a dynamic behavior state of rubber by applying a condition similar to a dynamic driving condition of a tire when the adhesive force of an adhered substance formed as rubber or a rubber rolled substance is adhered is tested. Moreover, the method for testing dynamic adhesion of rubber and a rubber rolled substance comprises: a step (S10) for preparing a sample (10) for testing of a two layered structure having the size of horizontal 10-50 mm and vertical 100-200 mm while different rubber or a rubber rolled substance is adhered to each other; a step (S20) for vulcanizing the sample (10) for testing under the condition of the pressure of 50-100 tons and the temperature of 140-180°C; a step (S30) for performing a flexing test of 10-100 k cycles as one end of the sample (10) for testing whose vulcanizing is competed is fixed and the other end thereof is rotated in the range of 80-300 degrees; and a step (S40) for relatively evaluating the level of the adhesive force with respect to rubber and a rubber rolled substance by confirming interface growth generated in the sample (10) for testing. |
