摘要:
A multiphase composite lubricant for a railway lubricant stick that can be used in both low and high temperature applications. The composition of the multiphase composite lubricant includes an amount of a lubricant, an amount of a thermoplastic lattice components that forms a lattice structure, and a polymer extender.
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.
摘要:
In a threaded joint for pipes constituted by a pin and a box, each having a contact surface comprising a threaded portion and an unthreaded metal contact portion, the contact surface of the pin has a solid corrosion protective, preferably transparent coating based on a UV-curable resin and the contact surface of the box has a solid lubricating coating having plastic or viscoplastic rheological behavior which is preferably formed by the hot melt technique from a composition comprising a thermoplastic polymer, a wax, a metal soap, a corrosion inhibitor, a water-insoluble liquid resin, and a solid lubricant.
