<p>PROBLEM TO BE SOLVED: To provide a method for making reclaimed rubber to recycle to a tire that has superior fracture property, wear resistance, crack growth resistance and exothermic property by pulverizing waste rubber with a little energy. SOLUTION: This method for making reclaimed rubber comprises blending 100 pts.wt. of raw reclaimed rubber of 100-300 mesh with 3-50 pts.wt. of diene rubber and shearing them at a maximum shear rate of 300/s or more. The period of time of shearing is decided such that the product of the maximum shear rate and the period of time of shearing is 15,000 or more. Then, the raw reclaimed rubber may be desulfurized after pulverization.</p> |
