Definitions

  • HNBR hydrogenated nitrile butadiene rubber
  • ACM alkylated chlorosulfonated polyethylene
  • a rubber composition comprising:
  • a power transmission belt produced from a rubber composition comprising:
  • ACSM used in the present invention
  • EVM is available from Bayer as LEVAPREN 500HV.
  • Typical of the peroxide cure co-agents are trimethylolpropane trimethacrylate, trifunctional organosiloxanes, triallyl cyanurate and triallyl isocyanurate, 1,3-butylene glycol dimethacrylate, ethylene glycol dimethacrylate, and n, n' -m-phenylene-dimaleimide-1, 2-cis- polybutadiene. While from 0.5 to 10 phr of the co-agent can be used, 1 to 4 phr are preferred.
  • Typical of the organic peroxides which can be used with invention are 1, 3-bis (t-butylperoxy-1-propyl) benzene, dicumyl peroxide, ⁇ , ⁇ -bis (t-butylperoxy) valerate, ⁇ , ⁇ -bis(t- butylperoxy) diisopropyl benzene, 2, 5-dimethyll-2, 5-di (t- butylperoxy) hexane, 1, 1-bis (t-butylperoxy) -3, 3, 5- trimethylcyclohexane, n-butyl-4, 4-bis (t-butylperoxy) valerate, and ethyl-3, 3-bis (t-butylperoxy) butyrate..
  • a series of blends of ACSM/EVM were compared to an all ACSM compound, an all EVM compound and three compounds known to be used in positive drive belts comprising a sulfur cured HNBR, a peroxide cured HNBR and a Neoprene for: a) percent of torque S' at 38°C which is retained at 135°C; b) oil resistance as percent volume swell after aging seventy hours at 100°C in IRM 903 oil; and c) the change in 10% modulus of each compound after being in oven for 168 hours @ 135°C.
  • the results are shown in Tables 3, 4 and 5 respectively.
  • modulus retention results further show an unexpected synergistic effect between the ACSM and EVM, such that the %S' retained for certain blend ratios is higher than for ACSM or EVM alone.
