Abstract

The invention discloses a low-volatility clean and anti-oxidative high temperature chain oil and a blending method thereof. The chain oil includes 30-70 wt% of dipentaerythritol, 10-30 wt% of alkylnaphthalene, 2-20 wt% of poly-alpha-olefin and 1-5 wt% of a high temperature antioxidant. The chain oil has the characteristics of unique formula, excellent anti-oxidation property, good lubrication anddetergency, less coking and low evaporation loss, and is low-volatility clean high temperature chain oil especially suitable for lubricating chains of printing and dyeing industry heat setting machines, wood manufacturing processing, high temperature ovens and other devices, and the prepared high temperature chain oil is suitable for lubricating chains with the ambient temperature of 260 DEG C orbelow, has a smaller volatility than traditional high temperature chain oils, reduces oil mists generated during use, meets the requirements of environmental protection, can reduce the use consumptionof lubricating oil, and achieves the purposes of reducing sludge formation and coking at a high temperature and keeping the cleanness of the chains for a long term by matching the high-performance amine antioxidant complex.

Description

technical field [0001] The invention relates to the technical field of high-temperature chain oil, in particular to a low-volatility clean high-temperature anti-oxidation chain oil and a preparation method thereof. Background technique [0002] With the rapid development of my country's textile printing and dyeing, wood processing, transportation and other industries, the main production equipment is developing towards more efficient and intelligent integration, and the working temperature and load of the corresponding equipment transmission system are getting higher and higher. The development of chain oil has gone through from low-grade to high-end, from mineral oil type, polyisobutylene, polyether type to synthetic ester type. 1. Polyethylene glycol ether type high temperature chain oil has the characteristics of good lubricating performance, but its applicable temperature is low, it is easy to decompose at high temperature, and it volatilizes too fast above 220 ℃, and the ...
