Lubricant and Functional Fluid Additive Package, and Lubricants and Functional Fluids Containing Same

摘要

Provided is a lubricant or functional fluid composition of a lubricating viscosity and including: an oil, which may include one or more polyalphaolefins; an anti-wear component which may include alkylated triarylphosphate and partially esterified alkyl phosphate; an antioxidant component which may include alkylated phenyl-alpha-naphthylamine, phenyl-alpha-naphthylamine and mixtures thereof; an anti-rust component including an alkenyl succinic acid ester anti-rust agent; and a metal deactivator component including a tolytriazole derivative. Also included are additives and additive kits for combining with an oil to form the a lubricant or functional fluid composition.

1. A lubricant or functional fluid composition of a lubricating viscosity and comprising:
(a) a polyalphaolefin having a viscosity of about 10 centiStokes at 100° C. and present in said lubricant or functional fluid composition in a range of from about 84 percent to about 88 percent by weight; (b) a polyalphaolefin having a viscosity of about 40 centiStokes at 100° C. and present in said lubricant or functional fluid composition in a range of from about 11 percent to about 13 percent by weight; (c) an anti-wear component consisting essentially of 95% isopropylated triarylphosphate and 5% dodecyl phosphate, said dodecyl phosphate being only partially esterified, said anti-wear component present in said polyolefin oil blend in a range of from about 1.00 percent to about 2.00 percent by weight, said anti-wear component being characterized by an acid value from about 10 mg KOH/g to about 15 mg KOH/g; (d) an antioxidant component selected from the group consisting of alkylated phenyl-alpha-naphthylamine, phenyl-alpha-naphthylamine and mixtures thereof, and present in said polyolefin oil blend in a range of from about 0.75 percent to about 2.00 percent by weight; (e) an anti-rust component comprising an alkenyl succinic acid ester anti-rust agent, and present in said polyolefin oil blend in a range of from about 0.025 percent to about 0.075 percent by weight; and (f) a metal deactivator component comprising a tolytriazole derivative, and present in said polyolefin oil blend in a range of from about 0.025 percent to about 0.075 percent by weight.
