Abstract
A rubber composition has a base rubber, a filler which is a protein, including soy protein, derived from byproducts resulting from the manufacture of biodiesel fuel and a coupling agent.
Claims12
A rubber composition comprising:
- (a) a base rubber, said base rubber being a member selected from the group consisting of natural rubber, styrene butadiene rubber (SBR), nitrile butadiene rubber (NBR), polybutadiene, ethylene-propylenediene monomer rubber (EPDM), styrene isoprene butadiene rubber (SIBR), isoprene butadiene rubber (IBR) and combinations thereof;
- (b) soy protein;
- and
- (c) a coupling agent.

A tire having a rubber composition comprising:
- (a) a non-functionalized base rubber, said base rubber being a non-functionalized member selected from the group consisting of natural rubber, styrene butadiene rubber (SBR), nitrile butadiene rubber (NBR), polybutadiene, ethylene-propylenediene monomer rubber (EPDM), styrene isoprene butadiene rubber (SIBR), isoprene butadiene rubber (IBR) and combinations thereof;
- (b) soy protein;
- and
- (c) a silane coupling agent interactive with said base rubber and said soy protein, the amount of said silane coupling agent being in the range of 1% to 20% by weight of said soy protein, said silane coupling agent being a member selected from the group consisting of bis(3-triethoxysilylpropyl)tetrasulfide (TESPT), mercaptopropyltrimethoxysilane, bis(3-triethoxysilylpropyl)disulfide (TESPD) and combination thereof;
- said soy protein being chemically bonded to said silane coupling agent during in-situ mixing of said soy protein, said silane and said non-functionalized base rubber.
