Abstract

The invention provides base oil, in particular to a neopentyl polyalcohol dibasic acid complex ester. The neopentyl polyalcohol dibasic acid complex ester is prepared in a way that: completely esterifying C5-12 binary fatty acid carboxyl with the mixture of neopentyl glycol, trimethylolpropane and pentaerythritol, and blocking with C14-20 unsaturated monobasic fatty acid. The base oil provided bythe invention has the characteristics of high flash point, high flammability point, low pour point, high viscosity index, low evaporation loss, high thermal oxidation stability and high biodegradation rate. The invention can be used as syntholube and grease base oil, especially syntholube base oil used under the conditions of high temperature and high pressure. The invention is especially suitable to be used in fire resistant hydraulic fluid, high-temperature chain oil, high-temperature grease and the like in severe working spaces at which naked flame can is accessible under the conditions ofhigh temperature and high pressure.

Description

technical field The invention relates to a lubricating oil and a lubricating grease base oil and a preparation method and application thereof, in particular to the preparation and application of a hydraulic oil base oil, and belongs to the technical field of industrial lubricating oil. Background technique Hydraulic machinery has been widely used in industries such as iron and steel, electric power, coal and machinery. As a power medium, hydraulic oil is the key material of hydraulic transmission technology, and it is also one of the three important oil products with the largest consumption of industrial lubricating oil. With the continuous development of modern hydraulic technology, some hydraulic systems often work under high pressure and high temperature conditions. More stringent requirements are placed on the flame resistance of the hydraulic oil used. Before the 1970s, countries devoted themselves to the development of water-containing emulsions (W / O and O / W types), ...
