Embodiment Construction

[0016] The preparation of this marine system oil can be formulated from 95% base oil and 5% additives. Among them: the base oil is composed of 65:35 intermediate base oil and paraffin base oil and 100 ℃ 10mm 2 / s~30mm 2 / s It is compounded with oils of different viscosities; the additives include the following components:

[0017] High base calcium naphthenate 1.5%;

[0018] Bis-succinimide 0.8%;

[0019] Zinc Dioctyldithiophosphate 0.8%;

[0020] Medium base number calcium alkyl salicylate 1.8%;

[0021] Fatty amide 0.05%;

[0022] Polyoxypropylene polyoxyethylene block polyether 0.05%;

[0023] Silicone oil 10-20ppm.

[0024] The composition is prepared in a stainless steel mixing kettle. The blending kettle should be heated with a jacket and the temperature can be controlled. The modulation sequence is: first add the base oil, heat up and stir. Add fatty acid amide (R-CONH 2 ), high base value calcium naphthenate, bisuccinimide, medium base value calcium salicyla...

Abstract

The invention discloses a liquid composition of accessory ship diesel lubricate, which is characterized by the following: adopting middle basic oil as main component; mating fitful high-alkaline value calcium naphthenate, disuccinimide, dioctyl dithio-zinc phosphate, middle-alkaline alkyl calcium salicylate, high-grade lipoamide, polyoxypropylene polyoxyethylene block-typed polyether and silicon oil; allocating the system oil through scientific method.

Description

Technical field: [0001] The invention relates to a liquid composition suitable for lubricating crankcases of low-speed crosshead two-stroke and high-power diesel engines, and also suitable for lubricating marine auxiliary engine diesel engines and the like. Background technique: [0002] The main functions of crosshead engine crankcase oil (system oil) are lubrication, sealing, cleaning, neutralizing acid and cooling. Traditional formulations are typically made with high viscosity index paraffinic base stocks. In order to prevent the additives in the system oil from being hydrolyzed and emulsified by water, the antioxidant and anticorrosion zinc dioctyl dithiophosphate (ZDDP) is often used less or not, thus affecting the antioxidant stability of the oil. The anti-rust function is weakened, and the carbon deposit is hard and difficult to remove, so the content of metal detergent needs to be increased. As a result, the anti-wear performance of the system oil is not ideal. ...
