Embodiment 1

[0014] Example 1: The weight percentage distribution ratio of the composite additive is: 69.5 parts of 300TBN calcium naphthenate, 13.9 parts of sulfurized calcium phenate, 10.4 parts of succinimide, 4.5 parts of zinc dialkyl dithiophosphate, carbamic acid 0.7 parts of zinc, 1.0 parts of benzotriazole, and the alkali value of calcium naphthenate is 320 mgKOH / g.

[0015] The production method of the composite additive: add 300TBN calcium naphthenate, calcium sulfide alkylphenate, succinimide, zinc dialkyldithiophosphate, zinc carbamate, and benzotriazole in sequence to stainless steel to adjust the above ratio. In the combined kettle, stir and heat up to 90°C, and continue to stir for 8 hours until the compound additive is clear and transparent.

Abstract

The invention discloses a marine cylinder oil compound additive and its production method and marine cylinder oil prepared from the marine cylinder oil compound additive. The compound additive adopts naphthenate as a main agent. Compared with sulfonate, sulfurized alkyl phenate and salicylate, naphthenate has excellent water resistance, a high acid neutralization speed and good diffusibility. The marine cylinder oil compound additive is a good raw material for production of marine cylinder oil. The naphthenate as a main agent and sulfurized alkyl phenate and salicylate as auxiliary agents display their respective advantages and produce synergism so that the compound additive has good water resistance, diffusibility, a high acid neutralization speed, abrasion resistance and cleanliness. The 70TBN marine cylinder oil prepared from the marine cylinder oil compound additive reaches a foreign reference oil quality level in physical and chemical analysis and simulation assessment.

Description

technical field [0001] The invention belongs to the field of petrochemical industry, and in particular relates to a composite additive for marine cylinder oil, a production method thereof and the blended marine cylinder oil. Background technique [0002] Marine cylinder oil can be divided into 10TBN, 40TBN, 70TBN and 100TBN models according to the base value. According to the different sulfur content of the fuel used by the ship, the marine cylinder oil with different base value is used to neutralize the sulfuric acid, Acid products such as sulfurous acid, among which: 10TBN marine cylinder oil is mainly used when the fuel sulfur content is not greater than 1.5%; 40TBN marine cylinder oil is mainly used when the fuel sulfur content is not greater than 2.5%; 70TBN marine cylinder oil It is mainly used when the fuel sulfur content is not more than 3.5%; 100TBN marine cylinder oil is mainly used when the fuel sulfur content is not more than 5.0%. In consideration of environmen...
