    • A slide way lubricant composition includes at least (a) a hydrotreated petroleum having a viscosity of from about 10 cSt to about 250 cSt as measured at 40 DEG C and consisting predominantly of hydrocarbons having from about 15 to about 50 carbon atoms per molecule and (b) a polymeric synthetic ester having an average molecular weight of at least about 200,000. The hydrotreated petroleum may be employed in an amount of from about 97.8 to about 99.4 weight percent and the ester may be employed in the composition in an amount of from about 0.6 to about 2.2 weight percent. The ester may be derived from the reaction between a dicarboxylic acid and a polyhydric alcohol. The composition may further include an adhesion additive having an average molecular weight of at least about 1,000,000 and a high pressure agent, such as a trisulfide. A demulsibility agent may also be employed. Another embodiment is a method of making the slide way lubricant composition which includes heating the hydrotreated petroleum to a temperature of from about 90 DEG F to about 120 DEG F and blending the polymeric synthetic ester and any other desired components or additives into the headed hydrotreated petroleum. Another embodiment is a method of lubricating a slide way having bearings which includes applying a lubricant composition to the bearings wherein the lubricant composition includes the above described hydrotreated petroleum.
    • 滑动方式润滑剂组合物至少包含(a)在40℃下测量的粘度为约10cSt至约250cSt的加氢处理石油,主要由每分子具有约15至约50个碳原子的烃和( b)平均分子量为至少约200,000的聚合合成酯。 加氢处理的石油可以以约97.8至约99.4重量%的量使用,并且酯可以以约0.6至约2.2重量%的量用于组合物中。 酯可以衍生自二羧酸和多元醇之间的反应。 该组合物还可包含平均分子量至少为约1,000,000的粘合添加剂和高压剂如三硫化物。 也可以使用破乳剂。 另一个实施方案是制备滑动润滑剂组合物的方法,其包括将加氢处理的石油加热至约90°F至约120°F的温度,并将聚合合成酯和任何其它所需组分或添加剂混合入带头的加氢处理的石油 。 另一个实施方案是润滑具有轴承的滑动方式的方法,其包括将润滑剂组合物施加到轴承,其中润滑剂组合物包括上述加氢处理的石油。
