| Abstract: |
| The influences of RD-F activated rubber crumb and its loading level on the curing characteristics and rheological properties of the compound，as well as the physical properties and dynamic compression fatigue property of its vulcanizate were investigated by using the non-acti-vated rubber crumb as the control.The affection mechanism was preliminary discussed in theory.The test results showed that the curing charateristics of the compound with rubber crumb up to 15 phr was by and large not influenced；the die swell decreased further when compared with the non-activated rubber crumb compound；the tensile strength and elongation at break of the vulcanizate decreased，the modulus at 300%.the temperature rise of compression fatigue and the compression set increased，and the tear strength reached maximum，as the loading level of RD-F activated rubber crumb increased；and the changes of the properties were much smaller than those of the vulcanizate with non-activated rubber crumb. |
