Embodiment 1

[0007] A compound diesel engine oil formula, the raw materials in the formula are composed by weight percentage: 75% of O light diesel oil, 1% of C9 hydrocarbons, 1% of sodium hydroxide, 5% of extreme pressure antiwear agent, alkyl water Calcium sylate 3%, zinc dialkyl dithiophosphate 3%, at this time, the composite diesel engine oil has poor corrosion resistance.

Embodiment 2

[0009] A compound diesel engine oil formula, the raw materials in the formula are composed by weight percentage: No. O light diesel oil 85%, C9 hydrocarbon 5%, sodium hydroxide 10%, extreme pressure antiwear agent 15%, alkyl water Calcium sylate 9%, zinc dialkyl dithiophosphate 5%, at this time the cost of compound diesel oil is relatively high.

Embodiment 3

[0011] A compound diesel engine oil formula, the raw materials in the formula are composed by weight percentage: 80% of O light diesel oil, 3% of C9 hydrocarbons, 5.5% of sodium hydroxide, 10% of extreme pressure antiwear agent, alkyl water Calcium sylate 6%, zinc dialkyl dithiophosphate 4%, at this time, the composite diesel engine oil has good corrosion resistance.

Abstract

The invention discloses a compound heavy diesel formula. The compound heavy diesel formula is prepared from the following raw materials in percentage by weight: 75 to 85 percent of No.0 light diesel oil, 1 to 5 percent of hydrocarbon compound of C9, 1 to 10 percent of sodium hydroxide, 5 to 15 percent of an anti-wear reagent at extreme pressure, 3 to 9 percent of calcium alkyl salicylate and 3 to5 percent of zinc dialkyl dithiophosphate. The compound heavy diesel disclosed by the invention has good corrosion resistance.

Description

technical field [0001] The invention is a compound diesel engine oil formula, which belongs to the field of mechanical equipment. Background technique [0002] In the field of machinery, various engineering materials are often used, but engineering materials are often exposed to the sun when placed in the external environment, and strong ultraviolet rays can cause diesel corrosion. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a compound diesel engine oil formulation, and the compound diesel engine oil has good corrosion resistance. [0004] In order to achieve the above object, the present invention is realized through the following technical scheme: a kind of composite diesel engine oil, the raw materials in the formula are composed respectively by weight percentage: No. O light diesel oil 75-85%, C9 hydrocarbon 1-5%, hydrogen Sodium oxide 1-10%, extreme pressure antiwear agent 5-15%, ...
