Development of oil, freeze, high temperature resistant and flame retardant rubber compounds for high performance hydrolic hose

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.
