Very high friction elastomer formulation for use in static braking applications |
摘要 |
A high friction brake shoe formulation having a high static friction coefficient in shear of about 1.5 and low adhesion to materials having microscopic pores therein in contact with said brake shoe formulation which comprises a mixture of about 75 phr of neoprene W rubber and about 25 phr of neoprene WHV rubber; a first curing system comprising about 1 phr of a fatty acid, about 5 phr of ZnO, and about 1-3 phr of MgO; and a second curing system comprising about 1.25 phr of sulfur and about 0.6 phr of a sulfur accelerator; together with about 50 phr of a reinforcing agent of N555 or N650 carbon black.
