Embodiment 1

[0052] According to the following formula:

[0053] Di-2-octyl sebacate 48kg

[0054] Polyethylene glycol sebacate (polyethylene glycol M: 2200) 28kg

[0055] Decyl methacrylate 6.5kg

[0056] Calcium 12-Alkylphenate 5.2kg

[0057] Monoalkenylsuccinimide 6.5kg

[0058] Calcium Thiooctyl Phosphate Aminoate 1.4kg

[0059] Dithiodecylaniline 5.0kg

[0060] Benzothiazole 0.08kg

[0061] Polyethyl acrylate (polyacrylic acid M: 1200) 0.4kg

[0062] Preparation process: 1) Preparation of base oil Add di-2-octyl sebacate and polyethylene glycol sebacate respectively into a stirring container, and stir for 1 hour under normal pressure and temperature of 60°C , so that it is evenly mixed to be the base oil.

[0063] 2) Adjustment of functional additives:

[0064] Take 1 / 3 of the base oil into a container with stirring, and then add calcium octyl phenate, monoalkenyl succinimide, sulfurized octyl calcium aminophosphate, dimerized decanyl aniline sulfide, Add benzothiazole and p...

example 1

[0066] The lubricating oil composition obtained in Example 1 was tested in Wuhan at 40°C. The user reported that the oil was good in driving. It has been driven for more than 380,000,000 kilometers, and the car is still running. In December 2005 in Harbin (the ambient temperature dropped to -43.5°C on December 21-22), the user reported that the driving was good, the low-temperature starting performance was good, and the fuel consumption was low. Among them, the Passat’s driving time was as long as 45,700 kilometers, and the car was still in operation. Continuing to run.

[0067] The lubricating oil that example 1 obtains uses CEC-L 33 -T93 method to measure biodegradation, the preliminary test result of biodegradation shows that the degradation rate has reached 75%, and the experiment is still in progress.

[0068] CEC-L 33 -T93 method is from CEC (European Confederation) -L 33 -T82 got it.

Abstract

A lube-oil composition as castor oil consists of decanedioic acid-2-octester 47-50 proportion, polyvinyl glycol-ester sebate 28-30 proportion, methyl-polyacrylate 5.8-6.5 proportion, alkylphenol calcium 5.2-5.5 proportion, mono-succimide or diene-succimide 5.5-6.5 proportion, alkyl amino sulfate calcium orthophosphate 1.4-1.8 proportion, dimeric alkyl monosulfide aromatic amine 5.0-5.4 proportion, benzothiazole or benzotriazole 0.1-0.15 proportion, polyacrylate ethyl ester 0.3-0.5 proportion. It is cheap, non-toxic and low-volatile, has excellent degradative and lubricating performances, higher viscosity index and less consumption.

Description

Technical field: [0001] The invention relates to a lubricant for mechanical transmission, in particular to a lubricating oil composition using castor oil as a raw material. Background technique [0002] The most popular lubricating oil products in my country's market are mostly petroleum-based lubricating oils, which are difficult to degrade and remain in the environment for almost a long time. The annual global consumption of lubricating oil is 36 to 40 million tons, of which about 10 million tons of lubricating oil directly enter the ecological environment where humans live due to leakage, splashing, oil vapor evaporation, packaging residues, improper disposal, etc., seriously polluting soil and water resources and destroy the ecological environment. [0003] In the late 1970s, biodegradable lubricating oil appeared in the European market, and the Chinese government is also very concerned about the pollution of lubricating oil. Therefore, the market has recently launched...
