Embodiment 1
[0026] The preparation method of energy-saving diesel engine oil comprises the steps of:
[0027] (1) Preparation components:
[0028] 67% base oil: 95% polyalphaolefin PAOs and 5% alkylnaphthalene ANs composite; PAOs is the composite of PAO4 and PAO10 according to the mass ratio of 5:7; alkylnaphthalene ANs is the composite of AN5 and AN12 according to the mass ratio of 3:4 complex;
[0029] 3% anti-friction additive: 50% tungsten disulfide and 50% molybdenum disulfide co-doped compound;
[0030] 5% detergent: overbased sulfurized calcium alkylphenate;
[0031] 12% dispersant: 50% borated polyisobutylene succinimide T154B and 50% PIBSA-PE polyisobutylene succinic anhydride-polyisobutylene succinic anhydride;
[0032] 3% antioxidant: ZDTC zinc dialkyldithiocarbamate;
[0033] 10% viscosity index agent: OCP ethylene propylene copolymer, wherein the molar ratio of ethylene propylene is 48:52.
[0034] (2) Add base oils PAO4, PAO10, AN5, AN12 into the blending tank for blend...
