The lubricating oil was a hydrofinished, dewaxed, phenol extracted distillate from a mixed base crude oil. The refined oil had a viscosity at 100 F. of about 150 SSU and a viscosity index of about 95. The Fischer-Tropsch wax had a congealing point of about 205 F. (ASTMD938-49), and a 100 gram penetration value at 100 F. of below 2 (ASTM-Dl32 l-61T).
A comparison of the data of Table II confirms that blends of asphalt and lubricating oil alone (Blends A and B) will not enable one to meet the indicated allowable wire rope lubricant specifications because when the weight percent of the oil is increased, the penetration value of the blend becomes excessively high, whereas the addition of a minor amount of the Fischer-Tropsch wax enables one to increase the oil content of the compositions to lower its viscosity but without producing excessive increases in penetration. The factors even permit the indicated wire rope specifications to be met by the presence of about 3.5 weight percent of the Fischer-Tropsch wax in Blend G.
It is significant that a Fischer-Tropsch wax component having the hereinbefore designated properties can be used with the asphalt-oil blend to make the compositions of this invention for it has been found that substituting, for example, polyethylene for the wax does not produce a suitable protective lubricant for wire ropes. It has been found that when a straight chain polyethylene such as Epolene N-lO which has a penetration at 77 F. of 1.5 and a Ring and Ball softening point of 232 F., is blended with the same asphalt and oil whose properties have hereinbefore been enumerated, incompatible mixtures were obtained when the amount of polyethylene employed approached that needed to meet required specifications. When an oxidized polyethylene called Epolene E-lO having a penetration at 77 F. of 2 and a Ring and Ball softening point of 216 F., was blended with the asphalt and oil,
compatible mixtures were obtained when up to 20 weight percent of Epolene E-lO was added, but the blends failed to meet the specifications since the additions caused an increase, rather than a decrease, in viscosity of the asphalt oil blend.
