preparation example Construction

[0021] Its preparation method comprises the following steps:

[0022] Step 1: mix 66.2% to 91.6% of soybean oil by weight, 7% to 30% of castor oil by weight, 0% to 2% of water by weight, half of accelerator and antiwear agent, heat Raise the temperature to 85-95°C and continue heating for 0.5-1.5 hours, stir evenly, and cool to obtain lubricating oil.

[0023] Step 2: Weigh each component, add each component into the reaction kettle, add additives, wherein the additives include at least one of extreme pressure antiwear agent, rust inhibitor and antioxidant, and heat the mixture to 55- Stir at a constant temperature after 65°C, in which the viscosity increases -0.12%, and the content is -0.09%. Slowly add the catalyst while stirring, control the speed so that the catalyst is added in 20-40 minutes, catalyze for 2 hours, stop stirring, and stand still. Get synthetic lubricants.

[0024] Step 3: After mixing step 1 and step 2, add sodium dodecylbenzenesulfonate, polymethacrylat...

Abstract

The invention discloses environment-friendly synthetic lubricating oil and a preparation method thereof. The environment-friendly synthetic lubricating oil is prepared from the following raw materialsin parts by weight: soybean oil, castor oil, rapeseed oil, 1 to 2 parts of dodecenylsuccinic acid, 0.1 to 1 part of molybdenum dialkyl dithioformate, 2 to 5 parts of eleostearic acid, 2 to 3 parts oftall oil acid, methyl silicone oil grease, 0.5 to 2.5 parts of polymethacrylate, 0.5 to 2.5 parts of calcium salicylate, 0.5 to 2 parts of nano nickel, 0.5 to 2 parts of nano cobalt, 2 to 5 parts ofmolybdenum disulfide, 10 to 15 parts of carbon tetrachloride, accelerant, 5 to 9 parts of chlorinated paraffin, 4 to 10 parts of stearic acid, antiwear agent and 6 to 8 parts of methylsalicylic acid.The environment-friendly synthetic lubricating oil has an advantage of aiming at providing lubricating oil with good biodegradation performance and further low toxicity; the biodegradability of a lubricating agent can be decreased by some cleaning dispersants, which influence the activity and a nutritional component of a microbe, in the environment-friendly lubricating oil mixed and confected through the preparation method; however, some phosphorus and nitrogen containing additives are beneficial to the growth and the reproduction of the microbe, and therefore, the biodegradability of the lubricating agent can be improved.

Description

technical field [0001] The invention relates to a preparation method of lubricating oil, in particular to an environment-friendly synthetic lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil achieves the purpose of reducing energy consumption, saving energy and extending machine life by reducing friction and controlling wear. It plays an important role in production and daily life. With the wide use of lubricating oil, due to penetration, leakage, overflow And improper handling, about 1 / 3 of lubricating oil will cause harm to nature, the environment and human beings in the process of production, use and discharge. With the continuous strengthening of environmental protection awareness and environmental protection legislation, people pay more and more attention to the pollution caused by lubricating oil The problem is that environmentally friendly lubricating oil is environmentally tolerant lubricating oil or environmentally compat...
