摘要:
Provided are compositions, additives for forming compositions, methods of operating apparatus in fluid communication with the compositions, and apparatus comprising the compositions. For example, the composition may include a polyalphaolefin component of from about 95% to about 99.5% w/w. The composition may include an additive component. The additive component may include an anti-wear agent. The anti-wear agent may be from about 0.1% to about 2% w/w. The anti-wear component may be characterized by an acid value of at least about 1 mg KOH/g. The additive component may include an aryl amine antioxidant agent, an anti-rust agent, and a metal deactivator agent. The composition may be characterized by a kinematic viscosity at 100° C. of at least about 5 centiStokes, a viscosity index of at least about 80, and an acid value in mg KOH/g of between about 0.1 and about 1.

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.
摘要:
The present invention is a lubricant or functional fluid additive for a polyolefin oil blend, comprising a mixture of: (a) an anti-wear component consisting essentially of 95% isopropylated triarylphosphate and 5% dodecyl phosphate, the dodecyl phosphate being only partially esterified, the anti-wear component present in the polyolefin oil blend in a range of from about 0.75 percent to about 2.00 percent by weight; (b) an antioxidant component selected from the group consisting of alkylated phenyl-alpha-naphthylamine, phenyl-alpha-naphthylamine and mixtures thereof, and present in the polyolefin oil blend in a range of from about 0.75 percent to about 2.00 percent by weight; (c) an anti-rust component comprising an alkylated succinic acid ester anti-rust agent, and present in the polyolefin oil blend in a range of from about 0.050 percent to about 0.125 percent by weight; and (d) a metal deactivator component comprising a tolytriazole derivative, and present in the polyolefin oil blend in a range of from about 0.050 percent to about 0.125 percent by weight.
