Abstract

The invention provides a high-temperature chain oil composition and a preparation method thereof. The high-temperature chain oil composition includes: (a) synthetic ester base oil; (b) alkoxy phosphate anti-wear reagent at extreme pressure; (c) oiliness agent; (d) viscosity index improver; (e) antioxygen; and (f) anticorrosive, wherein the (a) synthetic ester base oil is a mixture of dipentaerythritol ester and aromatic ester. The high-temperature chain oil composition is adapted to using at high temperature, has good high-temperature performance, has no carbon deposition residual working at high temperature for a long time, is without dripping, has good wear-resisting anti-attrition and corrosion resistant performances, and has low friction coefficient and small chain abrasion. Moreover, the high-temperature chain oil composition has low toxicity, is easy to decompose, and is environmentally friendly.

Description

technical field [0001] The invention relates to a high-temperature chain oil composition, in particular to a high-temperature chain oil composition with excellent wear resistance, low oil sludge, low evaporation loss and low coking amount and a preparation method thereof. Background technique [0002] The chain is an important part of mechanical transmission and is widely used in many fields of industry. Chain oil is an important additive for chain use. It is mainly used to reduce friction, protect the chain and other components from wear, and also has anti-rust and buffer functions. In addition, high temperature chain oil also needs to have good heat resistance, which can protect and lubricate the chain under high temperature. Lubrication and protection of chains such as stretching machines and paint drying rooms in the automobile manufacturing industry. [0003] At present, the research on high temperature chain oil in the industry mainly focuses on high temperature perf...
