[0039] A kind of synthetic automobile gear lubricating oil that contains pentasulfide and animal oil is based on neopentyl polyol ester NPE-3, adding TDPS532 accounting for neopentyl polyol ester weight percentage is 0.35%; lard CD- 1 is 0.36%; P120 is 0.32%, prepared by mixing evenly.

Embodiment 2

[0041] A kind of synthetic automobile gear lubricating oil that contains pentasulfide and animal oil is based on neopentyl polyol ester NPE-3, adding TDPS532 accounting for neopentyl polyol ester weight percentage is 0.05%; lard CD- 1 is 0.03%; P120 is 0.02%, prepared by mixing evenly.

Embodiment 3

[0043] A kind of synthetic automobile gear lubricating oil that contains pentasulfide and animal oil is based on neopentyl polyol ester NPE-3, adding TDPS532 accounting for neopentyl polyol ester weight percentage is 0.1%; lard CD- 1 is 0.3%; P120 is 0.05%, prepared by mixing evenly.

[0044] prediction and verification

[0045] Lubricating oil additive formula selection X 1 = TDPS532,X 2 = Lard CD-1, X 3 =P120 (X1,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 = , Y 3 = , Y 1 is the maximum no-seize load, which indicates the load-carrying capacity of the lubricant, Y 2 Expressed as the wear scar diameter of the test ball when the load is 392N and the wear time is 60min; Y 3 It is expressed as the wear scar diameter of the test ball when the load is 392N and the wear time is 60 minutes.

Abstract

The invention discloses a synthetic automobile gear lubricating oil containing pentasulfide and animal oil. Neopentyl polyol ester is used as base oil for the lubricating oil, American product sulfurated extreme pressure agent polymeric pentasulfide TDPS532, lard oil CD-1 and P120 are added. Formula of the lubricating oil is shown as follows: neopentyl polyol ester is used as base oil, and 0.03-0.3% of TDPS532, 0.03%-0.36% of lard oil CD-1 and 0.02-0.32% of P120 by weight percentage of neopentyl polyol ester are added. The synthetic automobile gear lubricating oil containing pentasulfide and animal oil has superb extreme pressure abrasion resistance, bearing capacity is up to 2832N, wear scar is 0.426mm when load is 392N and abrasion time is 60min, and when load is 441N and abrasion time is 30min, the wear scar is 0.374mm. The synthetic automobile gear lubricating oil containing pentasulfide and animal oil can be used for preparing heavy load automobile gear oil, and also can be used for heavy load and medium load industrial gear oil.

Description

technical field [0001] The invention relates to the gear lubricating oil technology, in particular to a synthetic automotive gear lubricating oil containing pentasulfide and animal oil. Background technique [0002] Sulfur-containing extreme pressure agents polypentasulfide TDPS532, lard CD-1, phosphorus star P120 have excellent extreme pressure and anti-wear properties, and are mainly used in heavy-duty industrial gear oils. 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] Add pentasulfide TDPS532, lard CD-1, and phosphorus star P120 to the synthesis of neopentyl polyol ester, use artificial neural network method to optimize calculation, and carry out verification. Because it contains sulfur and phosphorus elements, it has a high load-carrying capacity, up to 2832N. The disadv...
