Embodiment 1
[0038] The present embodiment provides a kind of semi-solid high-strength film automotive lubricating oil additive, and its synthetic method is:
[0039] 1) Synthesis of organic molybdenum amine mixture:
[0040] Put molybdenum oxide, anthranilic acid, and alkylated diphenylamine in a container, and react under sealed conditions at 150°C for 2 hours, then wash with alkali and water, adjust the pH to 6.5, add potassium permanganate, and Continue to react at 80-100°C for 3 hours, then vacuum filter to obtain a precipitate, wash with water until neutral, and obtain a brown product which is a mixture of organic molybdenum amines; molybdenum oxide: anthranilic acid: alkylated diphenylamine: potassium permanganate =1:4:4:8 (weight ratio);
[0041] 2) Synthesis of molybdenum-titanium alloy lubricating oil additives:
[0042] Mix 5 grams of the above-prepared organic molybdenum amine mixture with 25 grams of calcium titanate and 75 grams of methyl methacrylate, stir evenly, and reac...
Embodiment 2
[0045] 1) Synthesis of organic molybdenum amine mixture:
[0046] Put molybdenum oxide, anthranilic acid, and alkylated diphenylamine in a container, and react under sealed conditions at 140°C for 2.5 hours, then wash with alkali and water, adjust pH=7, add potassium permanganate, Continue to react at 90°C for 3.5 hours, then vacuum filter to obtain a precipitate, wash with water to neutrality, and obtain a brown substance which is a mixture of organic molybdenum amines; molybdenum oxide: anthranilic acid: alkylated diphenylamine: potassium permanganate=1 :5:5:10 (weight ratio);
[0047] 2) Synthesis of molybdenum-titanium alloy lubricating oil additives:
[0048] Mix 10 grams of the above-prepared organic molybdenum amine mixture with 60 grams of calcium titanate and 160 grams of methyl methacrylate, stir evenly, and react for 5 hours at a temperature of 100°C and a pressure of 0.24MPa; cool to 60°C, add 160 grams of didodecanyl methyl tertiary amine, increase the temperatu...
Embodiment 3
[0051] 1) Synthesis of organic molybdenum amine mixture:
[0052] Put molybdenum oxide, anthranilic acid, and alkylated diphenylamine in a container, and react under sealed conditions at 145°C for 3 hours, then wash with alkali and water, adjust the pH to 6.5, add potassium permanganate, and The temperature is 95°C and the reaction is continued for 4 hours, and then vacuum filtered to obtain a precipitate, which is washed to neutrality to obtain a brown substance which is a mixture of organic molybdenum amines; molybdenum oxide: anthranilic acid: alkylated diphenylamine: potassium permanganate =1:3:3:9 (weight ratio);
[0053] 2) Synthesis of molybdenum-titanium alloy lubricating oil additives:
[0054] Mix 40 grams of the above-prepared organic molybdenum amine mixture with 320 grams of calcium titanate and 800 grams of methyl methacrylate, stir evenly, and react for 4.5 hours at a temperature of 95°C and a pressure of 0.28MPa; cool to 50°C, add Didodecyl methyl tertiary am...
