Example Embodiment
[0016] Example 1
[0017] Put 45 g of water-soluble polyether, 41.4 g of distilled water, and 11 g of stearic acid into the blending kettle, heat at 70-80° C. and stir evenly, and obtain a mixed solution after the dissolution is complete. Put 1g of calcium hydroxide and 0.55g of sodium hydroxide into the mixed solution and keep the temperature at 87~95℃ for 30min. After saponification, add 1 g of the composite solution of antiwear agent melamine cyanurate and zinc dialkyl dithiophosphate, 0.05 g of rust preventive agent benzotriazole, natural cooling to room temperature, grinding twice, and filtering to obtain the finished product.
Example Embodiment
[0018] Example 2
[0019] Put 30g of water-soluble polyether, 45g of distilled water, and 20g of stearic acid into the blending kettle, heat and stir evenly at about 70-80°C, and obtain a mixed solution after complete dissolution. Put 2g of calcium hydroxide and 1g of sodium hydroxide into the mixed solution, and keep the temperature at 87~95℃ for 30min. After saponification, 1.5 g of a composite solution of anti-wear agent melamine cyanurate and zinc dialkyl dithiophosphate, 0.05 g of rust preventive agent benzotriazole, natural cooling to room temperature, grinding twice, and filtering to obtain a finished product.
[0020] Tests on the finished product obtained in the above examples show that the water-based grease has a milky white appearance, a drop point of 100 or more, a penetration degree can reach the No. 1 hardness standard, and abrasion resistance can meet the requirements of basic metal processing conditions.
[0021] The invention uses water-soluble polyether as the bas...
