Embodiment 1
[0037] 1) According to the mass percentage of the constituent components of the nano-alumina slurry (deionized water 91%, NDZ201 titanate coupling agent 0.03%, nano-Al 2 o 3 4%, SN-5040 dispersant 0.1%, diethanolamine 0.3%, each component was weighed and prepared according to the following steps and process conditions: deionized water, NDZ201, nano-Al 2 o 3 , SN-5040, dimethylethanolamine, added to the container, and mechanically stirred (800r / min speed) while adding raw materials; after adding raw materials, first high-speed dispersion (2000r / min speed) for 8min and then ultrasonic Disperse (20KHz frequency) for 8 minutes to prepare nano-alumina slurry for later use.
[0038] 2) Add 6% deionized water, under the condition of stirring at 700r / min, add the composite film-forming aid (Texanol, 2.5% from Eastman Company of the United States, PnP, 2.5% from Dow Chemical) in the formula and stir for 8 minutes; wait for the solution to drop To room temperature, the film-forming a...
Embodiment 2
[0041] 1) According to the mass percentage of the components of the nano-alumina slurry (deionized water 97%, NDZ201 titanate coupling agent 0.07%, nano-Al 2 o 3 6%, Orotan 731A dispersant 0.4%, AMP950.7%) were weighed and prepared according to the following steps and process conditions: deionized water, NDZ201, nano-Al 2 o 3 , Orotan 731A, AMP95, added to the container, and mechanically stirred (1000r / min speed) while adding the raw materials; after the raw materials were added, first high-speed dispersion (2500r / min speed) for 12min and then ultrasonic dispersion (50KHz frequency ) for 12 minutes, that is, the nano-alumina slurry is prepared for use.
[0042] 2) Add 18% deionized water, under the condition of stirring at 900r / min, add the composite film-forming aids (PPh, Dow Chemical 1.5%, PnP, Dow Chemical 1.5%) in the formula and stir for 12min; To room temperature, the film-forming aid mixed solution is prepared for subsequent use;
[0043] 3) Add 85% of water-based...
Embodiment 3
[0045] 1) According to the mass percentage of the constituent components of the nano-alumina slurry (deionized water 95%, NDZ201 titanate coupling agent 0.05%, nano-Al 2 o 3 5%, SN-5034 dispersant 0.2%, ammonia water 0.2%) were weighed and prepared according to the following steps and process conditions: deionized water, NDZ201, nano-Al 2 o 3 , SN-5034, and ammonia water are added to the container, and mechanically stirred (900r / min speed) while adding the raw materials; after the raw materials are added, first high-speed dispersion (2200r / min speed) for 10min and then ultrasonic dispersion (30KHz Frequency) for 11 minutes, that is, the nano-alumina slurry is prepared for use.
[0046] 2) Add 10% deionized water, and under the condition of stirring at 800r / min, add the composite film-forming aids in the formula (propylene glycol methyl ether PM, Dow Chemical 1.5%, propylene glycol butyl ether PnB, Dow Chemical 3%) Stir for 10 minutes; when the solution drops to room temper...
