Example Embodiment
[0018] Example 1
[0019] Weigh 20 kg of rapeseed oil, 10 kg of mineral oil, 20 kg of lard, 1 kg of dodecenyl succinic acid, 1 kg of molybdenum dialkyl disulfate formate 1 kg, 2 kg of methyl silicone grease, 3 kg of polymethacrylate, and magnesium sulfonate 2kg, 3kg of butyloctyldiphenylamine, 10kg of pentaerythritol, 7kg of glycerol acrylate;
[0020] The mineral oil is the base oil extracted from petroleum at 163-184°C.
[0021] The preparation method is as follows:
[0022] ①. Pre-mix and stir the rapeseed oil, mineral oil, and lard in the raw materials until the mixture becomes a viscous paste to obtain material A;
[0023] ② Choose a stirred reactor to remove the raw materials from dodecenyl succinic acid, molybdenum dialkyl disulfate formate, methyl silicone grease, polymethacrylate, magnesium sulfonate, and butyl octyl diphenyl Add base amine, pentaerythritol and glyceryl acrylate, heat to 30-50°C, stir at constant temperature for 3-5min, and control the speed at 3000-4000r / min...
