Embodiment 1
[0020] First, prepare the lubricating carrier film layer: add 35kg of water to the reaction kettle, add 2.5kg of sodium hydroxide under stirring and slowly heat up to 50°C; then add 9kg of isobutylene-maleic anhydride copolymer and quickly heat up to 80°C. Slowly raise the temperature to 110°C under stirring until the liquid becomes clear, and keep it warm for 1 hour; adjust the pH value between 6 and 8 to obtain a lubricating carrier film layer, and set aside;
[0021] Next, prepare the lubricating slurry: add 72.8kg water, 1kg fatty acid polyethylene glycol ester and 1kg fatty alcohol polyoxyethylene ether into the high-speed homogeneous disperser and stir and mix, then add 5kg melamine-cyanuric acid complex, 10kg boric acid Zinc and 10kg of molybdenum selenide are dispersed at high speed, then 200g of polyether defoamer is added, and sheared and dispersed for 2 hours to obtain a uniform dispersion with a viscosity of 30mPa·S, an average particle size of 15μm, and a solid con...
Embodiment 2
[0025] First, prepare the lubricating carrier film layer: add 70kg of water to the reactor, add 5kg of potassium hydroxide under stirring and slowly heat up to 55°C; then add 18kg of isobutylene-maleic anhydride copolymer and quickly heat up to 90°C, Slowly raise the temperature to 120°C until the liquid becomes clear, and keep it warm for 1.2 hours; adjust the pH value between 6 and 8 to obtain a lubricating carrier film layer, and set aside;
[0026] Next, prepare the lubricating slurry: add 61.9kg of water and 3kg of fatty acid polyethylene glycol ester to the high-speed homogeneous disperser and stir and mix, then add 30kg of melamine-cyanuric acid complex and 5kg of nano-tungsten disulfide for high-speed dispersion, and then add 100g polyether defoamer, shear dispersion for 2.5 hours to obtain a uniform dispersion with a viscosity of 30mPa S, an average particle size of 15 μm, and a solid content of 38wt%, for subsequent use;
[0027] Again, prepare the release agent: add...
Embodiment 3
[0030] First, prepare the lubricating carrier film layer: add 80kg of water to the reaction kettle, add 10kg of ammonia water under stirring and slowly raise the temperature to 55°C; Raise the temperature to 140°C until the liquid becomes clear, and keep it warm for 2 hours; adjust the pH value between 6 and 8 to obtain a lubricating carrier film layer, and set aside;
[0031]Next, prepare the lubricating slurry: add 58.5kg of water, 2kg of fatty alcohol polyoxyethylene ether and 4kg of sodium lauryl sulfate into a high-speed homogeneous disperser and stir and mix, then add 20kg of zinc borate, 5kg of nano-tungsten disulfide and 10kg of Molybdenum selenide is dispersed at a high speed, and then 500 g of polyether defoamer is added, and sheared and dispersed for 3 hours to obtain a uniform dispersion with a viscosity of 20 mPa·S, an average particle size of 18 μm, and a solid content of 36 wt%, for subsequent use;
[0032] Again, prepare the release agent: add 66.55kg of water ...
