preparation example Construction
[0040] The present invention also provides a preparation method of the lubricating oil composition of the rotary kiln supporting wheel and large tile, which comprises the following steps:
[0041] Thickener, antioxidant, metal deactivator, corrosion inhibitor and antifoaming agent are added to base oil polyalphaolefin and bright oil in sequence, heated and stirred evenly under vacuum conditions to obtain rotary kiln supporting wheel tiles lubricating oil composition.
[0042] When the additive is selected as a composite agent, the preparation method is as follows:
[0043] The compounding agent and the antifoaming agent are sequentially added to the composition formed by the base oil polyalpha-olefin, the bright oil and the thickening agent, and heated and stirred evenly under vacuum conditions to obtain the lubricating oil composition for the rotary kiln support wheel large tile.
[0044] In the present invention, the heating temperature is preferably 45°C to 130°C, more pre...
