Embodiment 1
[0021] Step 1: Weigh the dispersant according to the number of parts and add it to water, stir evenly at a speed of 300r / min, and disperse evenly by ultrasonic to obtain a slurry;
[0022] Step 2: Add 15 parts of fluorine-containing acrylate monomers in batches to the slurry prepared in step (1); 3 parts of hexafluoroacetone; 2 parts of cyclochloroethane, then stir and disperse evenly, and the stirring speed is 280r / min, disperse at low speed for 10min, add 1.5 parts of pH regulator, 1.5 parts of initiator and 1 part of leveling agent in turn to obtain the mixed material;
[0023] Step 3: Add 20 parts of non-fluorine-containing monomers in the formula amount to the mixed material in step (2), stir and mix well, and then solidify to obtain a water-based fluorine-containing coating;
[0024] Step 4: The water-based fluorine-containing paint obtained in step (3) is inspected, and the water-based fluorine-containing paint that passes the inspection can be used after aging for 20 m...
Embodiment 2
[0026] Step 1: Weigh the dispersant according to the number of parts and add it to water, stir evenly at a speed of 500r / min, and disperse evenly by ultrasonic to obtain a slurry;
[0027] Step 2: Add 28 parts of fluorine-containing acrylate monomers in batches to the slurry prepared in step (1); 8 parts of hexafluoroacetone; 5 parts of cyclochloroethane, then stir and disperse evenly at a stirring speed of 480r / min, disperse at low speed for 25min, add 5 parts of pH regulator, 3 parts of initiator and 2 parts of leveling agent in turn to obtain the mixed material;
[0028] Step 3: Add 35 parts of non-fluorine-containing monomers in a formula amount to the mixed material in step (2), stir and mix well, and then cure to obtain a water-based fluorine-containing coating;
[0029] Step 4: The water-based fluorine-containing paint obtained in step (3) is inspected, and the water-based fluorine-containing paint that passes the inspection can be used after aging for 35 minutes.
Embodiment 3
[0031] Step 1: Weigh the dispersant according to the number of parts and add it to water, stir evenly at a speed of 350r / min, and disperse evenly by ultrasonic to obtain a slurry;
[0032] Step 2: Add 20 parts of fluorine-containing acrylate monomers in batches to the slurry prepared in step (1); 5 parts of hexafluoroacetone; 3 parts of cyclochloroethane, then stir and disperse evenly, and the stirring speed is 350r / min, disperse at low speed for 15min, add 3 parts of pH regulator, 2 parts of initiator and 1.5 parts of leveling agent in sequence to obtain the mixed material;
[0033] Step 3: Add 28 parts of non-fluorine-containing monomers in a formula amount to the mixed material in step (2), stir and mix well, and then solidify to obtain a water-based fluorine-containing coating;
[0034] Step 4: Inspect the water-based fluorine-containing paint obtained in step (3), and the water-based fluorine-containing paint that passes the inspection can be used after aging for 30 minut...
