Problems solved by technology

At present, there is no engine oil formulated for taxi engines. Generally speaking, although the selection of high-quality engine oil can meet the special working conditions of the engine, it is not specific to the working conditions of taxis and cannot suppress The generation of sludge cannot prolong the service life and cause economic waste

Embodiment 1

[0029] 1. Composition of lubricating oil for taxis (by mass percentage):

[0030]

[0031] Second, the preparation process:

[0032] 1) Modulation of base oil:

[0033] Add diisooctyl sebacate, polyethylene glycol sebacate and hydrogenated type III mineral oil respectively into a stirring container, and stir for 0.5 hours under normal pressure and temperature of 60-65°C, Make it evenly mixed to be the base oil.

[0034] 2) Modulation of functional additives:

[0035] Take 1 / 3 of the base oil and put it into a stirring container, then add calcium thioalkylphenate, dienyl succinimide, polyisobutylene succinate pentaerythritol ester, calcium thiooctyl aminophosphate , Dimerized decanylaniline sulfide, diphenylcarbodiimide, benzotriazole, and polyethylacrylate were sequentially added to the reaction vessel, stirred at normal pressure and temperature 65-70°C for 1 hour, and then filtered. That is, a uniform functional additive is obtained.

Abstract

The invention provides a castor-based derivative automotive lubricant, comprising, by mass, 30 to 40% of diisooctyl sebacate, 10 to 15% of polyethyleneglycol sebacate, 5 to 10% of a viscosity index improver, 1 to 5% of sulfurized calcium alkyl phenolate, 1 to 5% of a composite ash-free dispersant, 1 to 3% of calcium alkylamino-sulfophosphate, 0.5 to 5% of dipoly(alkyl arylamine) sulfide, 0.1 to 2% of carbodiimide, 0.05 to 0.15% of benzotriazol or 2-mercaptobenzothiazole and 0.1 to 0.2% of poly(ethyl acrylate) with low molecular weight, with the balance being hydrorefined group III mineral oil. The lubricant provided by the invention has excellent antioxidation performance, enables generation amount of oil sludge in the process of usage to be substantially decreased, has an ultra long service life, provides optimal protection for the engine of a taxi and reduces consumption of fuel oil. The invention further provides a preparation method for the castor-based derivative automotive lubricant.

Description

technical field [0001] The invention belongs to the field of lubricants, and more specifically relates to a castor-based derivative automotive lubricating oil composition and a preparation method thereof. Background technique [0002] Lubricating oil is the lubricant for the development of the national economy. It is known as "industrialized blood" and has a large development market. The level of a country's lubricating oil usage directly reflects the country's economic development level, equipment control status, production efficiency and Differences in environmental awareness. China has become the world's second largest lubricating oil consumer, and automotive lubricating oil accounts for more than 40% of China's total lubricating oil consumption. It is the fastest-upgrading type of lubricating oil and the main source of lubricating oil profits. Due to the large regional development in my country, lubricating oil products on the market almost cover all quality levels from...
