Abstract

The high
performance hydrolic rubber hose should resist to hydrolic oils and can run at
temperature interval from –55 0C to 150 0C. In addition
to these properties, for some areas such as mining should also be flame
retardant. In this study, compound formulations having properties mentioned
above were developped, mechanical properties, hydrolic oil and low, high
temperature resistance performances were measured. Flame retardant tests were
also been performed. Hoses were built using these newely developped compounds
and then their burst tests were performed. The best performer compound for low
temeperature performance hose was the one prepared with the blends of acrylonitrile
butadiene (NBR), stirene-butadiene  (SBR)
and cis-butadiene (CBR) rubbers along with plasticizer diisononylphthalate (DINP).
One of the compounds preapared with the blending of SBR, NBR rubbers, aluminium
hydroxide, tricrezyl phoshate (TCP) and zinc borate was the best for the flame
retardant hose. The best performer high temeperature resistant compound was
preapred using MT N990 carbonblack and plasticizer paraplex G50 with blending
of SBR 1502, NBR 2860 and NBR 3360 rubbers.
