Neopentyl polyol ester automobile gear lubricating oil containing sulphurized isobutylene

[0042] A neopentyl polyol ester automotive gear lubricating oil containing thienyl polyol ester, which is based on neopentyl polyol ester and added ester weight percentage: T321 is 0.35%; RC2540 is 0.39%; P120 is 0.32%, after mixing Made evenly.

[0044] A neopentyl polyol ester automotive gear lubricating oil containing thienyl polyol ester, which is based on neopentyl polyol ester and added with ester weight percentage: T321 is 0.05%; RC2540 is 0.03%; P120 is 0.02%, after mixing Made evenly.

[0046] A neopentyl polyol ester automotive gear lubricating oil containing thienyl polyol ester, which takes neopentyl polyol ester as the base oil and adds ester weight percentage: T321 is 0.2%; RC2540 is 0.3%; P120 is 0.1%, after mixing Made evenly.

[0047] Prediction and verification of T321, RC2540, P1 20 added to neopentyl polyol esters.

[0048] Lubricating oil additive formula selection X 1 = T321,X 2 =RC2540,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, 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 294N and the wear time is 20min. Experimental result Y 1 = The minimum value is 1577N, the initial value Pb ...
