[0043] The embodiment of the present invention also provides a preparation method of an antiwear and friction reducing agent, comprising the following steps: mixing the diluent oil with the dispersant and the antiwear and friction reducing composition after dehydration.
[0044] Specifically, the diluent oil is dehydrated at 90-150°C and a gauge pressure of -0.07 to -0.1MPa (-0.1MPa is an absolute vacuum state, which is generally impossible to achieve, so it can only be close to -0.1MPa) for 45-60 minute. The diluent oil may contain water, and the above conditions are used to dehydrate the diluent oil to make the diluent oil anhydrous, improve the stability of the anti-wear and friction reducer, and at the same time ensure its performance. Specifically, in a stainless steel reaction kettle with heating and vacuum, diluent oil is added, and then the temperature is raised and the pressure is reduced to stir and dehydrate.
[0045] Further, in order to improve the dehydration ef...
Embodiment 1
[0049] This embodiment provides an anti-wear and friction-reducing composition (100Kg), which includes 30.0Kg of molybdenum compound without sulfur and phosphorus, 10.1Kg of titanium-containing compound and 59.9Kg of ester compound. Among them, the molybdenum compound without sulfur and phosphorus is a molybdenum amine complex, specifically the molybdenum amine complex Molyvan855 (number V855) produced by R.T.Vanderbilt Company, and the titanium-containing compound is tetraisopropyl titanate (number V311) , the ester compound is a polymer polyester compound, specifically Priolube 3986 (number P3986) produced by Croda Company.
[0050] The present embodiment provides a kind of antiwear and friction reducing agent (100kg), and it comprises diluent oil, dispersant and above-mentioned antiwear and friction reducing composition, wherein the quality of antiwear and friction reducing composition accounts for the mass of described antiwear and friction reducing agent 35.7%, the qualit...
Embodiment 2- Embodiment 7
[0055] The basic components of the anti-wear and friction-reducing composition and the anti-wear and friction-reducing agent provided in Example 2-Example 7 are consistent with those of the anti-wear and friction-reducing composition and the anti-wear and friction-reducing agent in Example 1, except that the used Ratios and specific compounds vary. The preparation methods of the antiwear and friction reducers provided in Examples 2 to 7 are basically the same in operation, except that the specific operating conditions are different.
