[0041] Take neopentyl polyol ester as base oil to add and account for neopentyl polyol ester weight percent:

[0042] TDPS532 is 1.5%; RC6340 is 1.5%; CL349 is 1.5% Mix and stir evenly to obtain.

Embodiment 2

[0044] Take neopentyl polyol ester as base oil to add and account for neopentyl polyol ester weight percent:

[0045] TDPS532 is 1.5%; RC6340 is 2.1%; CL349 is 0.4% Mix and stir evenly to obtain.

Embodiment 3

[0047] Take neopentyl polyol ester as base oil to add and account for neopentyl polyol ester weight percent:

[0048] TDPS532 is 2.1%; RC6340 is 0.8%; CL349 is 1.5% Mix and stir evenly to get.

[0049] Validate Lubricant Additive Formulations

[0050] Lubricating oil additive formulation selection X 1 = TDPS532,X 2 =RC6340,X 3 = CL 349 (X 1 , X 2 and x 3 Mass percent) a total of 3 factors and 7 levels were investigated, and neopentyl polyol ester was used as the base oil. The investigation target is the dependent variable Y 1 =Pb,Y 2 =Pd,Y 3 = , Y 1 is the maximum no-seize load, which indicates the load-carrying capacity of the lubricant, Y 2 For sintering loads indicate the ultimate load carrying capacity at and Y 3 It is expressed as the wear scar of the test ball when the load is 441N and the wear time is 30 minutes. Experimental result Y 1 = between Pb =1061.702-2144.524N, Y 2 = Pd = between 3349.961 N-7845N, Y 3 =0.281-0.479mm. See attached figure 1 , ...

Abstract

The invention relates to neopentyl polyol ester automobile gear lubricating oil which is prepared by taking neopentyl polyol ester as base oil, adding an American product sulfur-containing type extreme pressure additive, namely polypentasulfide TDPS532, dibutylthiocarbamate RC6340 from Rheinland Company and a food-grade additive CL349, and uniformly mixing. A formula is as follows: neopentyl polyol ester is taken as base oil; by calculation on the basis of neopentyl polyol ester, 0.3-4.2% of TDPS532, 0.8-5.6% of RC6340 and 0.4-2.8% of CL349 are added. The neopentyl polyol ester automobile gear lubricating oil provided by the invention has excellent extreme pressure anti-wear performance, high bearing capacity of 2144.524N and relatively high sintering load of 7845N, and can be used for configuring heavy-load vehicle gear oil as well as heavy-load and medium-load industrial gear oil.

Description

technical field [0001] The invention relates to lubricating oil technology, in particular to a neopentyl polyol ester automotive gear lubricating oil. Background technique [0002] The sulfur-containing extreme pressure agent polypentasulfide TDPS532 is Rheinland's dibutyldithioformamide RC6340, and the food-grade additive Ciba? IRGALUBE? 349 mainly has excellent extreme pressure and anti-wear properties and is mainly used in heavy-duty industries. Gear Oil. A physisorbed film and a chemically reacted film have been formed to increase its load carrying capacity. It is mainly used to configure heavy-duty vehicle gear oil, and can also be used for heavy-duty and medium-duty industrial gear oil. [0003] The pentasulfide TDPS532 is added to the synthetic oil neopentyl polyol ester, and the ratio of dibutyldithioformamide RC6340 of Rheinland Company and the sulfur-containing food grade additive Ciba?IRGALUBE?349 is mainly carried out, using artificial neural network The metho...
