Embodiment 1
[0027] Prepare microcapsule type speed-increasing anti-seize lubricant according to the following steps:
[0028] (1) Preparation of lubricating oil: Prepare the following raw materials in parts by mass: 30 parts of plant asphalt, 20 parts of sorbitan diester, 40 parts of B20 biodiesel, 10 parts of polyoxyethylene lauryl ether; Environmentally friendly lubricating oil is prepared by compounding raw materials;
[0029] (2) Preparation of capsule wall prepolymer: Under the protection of nitrogen, add a certain amount of starch and distilled water into a four-neck flask, gelatinize at a temperature above 80°C for 30 minutes, and at the same time stir it electrically to make it uniform, and control the reaction temperature to 40°C. Then add 2-acrylamide-2-methylpropanesulfonic acid, dimethyl diallyl ammonium chloride and ammonium cerium nitrate successively, stir and react for 2 hours, and obtain a total concentration of 3% capsule wall prepolymer; wherein , The mass ratio of dim...
