Embodiment Construction

[0019] The lubricating oil additive formula is selected as X1=T321, X2=RC2540, X3=P110 (X1, X2 and X3 mass percentages), a total of 3 factors and 7 levels for investigation, and neopentyl polyol ester is used as the base oil. The investigation target is the dependent variable Y1=Pb, Y2=Pd, Y1 is the maximum non-seizing load, which indicates the bearing capacity, Y2 is the sintering load, indicating the ultimate bearing capacity and Y3 indicates the wear scar of the test ball when the load is 294N and the wear time is 20min.

[0020] Since there are three components that affect the formulation of lubricant additives, the inspection objectives are also three, corresponding to the three independent variables of the uniform design and the three input nodes and three output nodes due to the surface energy or the neural network. Optimize design calculations. According to the correlation analysis, the three components in the lubricating oil additive formula interact with each other...

Abstract

The invention discloses a lubricating oil. The formula of the lubricating oil is that neopentyl polyol ester is taken as a base oil and T321, RC2540 and / or P110 are / is added to the base oil. The lubricating oil provided by the invention is high in bearing capacity, which is more than 290 kg at most.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a lubricating oil and a preparation method thereof. Background technique [0002] Phosphorus-containing extreme pressure agents mainly include Phosphorous Star P120 and Phosphorous Star P110. Phosphorus Star P120 has excellent extreme pressure and anti-wear properties, and is mainly used for heavy-duty industrial gear oils. Phosphorus Star P120 is an alkyl phosphate produced by reacting low-carbon alcohols with phosphorus oxychloride, and then reacting with organic amines and phosphate esters. Due to the small alkyl group of the organic amine and the high extreme pressure performance, a physical adsorption film and chemical reaction have been formed, thereby improving its carrying capacity. Phosphorous Star P110 is a reaction product of phosphite and formaldehyde, plus P 2 o 5 Alkyl phosphate is generated, amine and phosphoric acid react with organic amine to form phosphorous...
