Embodiment 1
[0033] In a 500ml four-necked bottle, add 80 grams of methyl methacrylate, 15 grams of butyl acrylate, 5 grams of acrylic acid and 0.5 grams of azobisisobutyronitrile, pre-react at 60 ° C for 1 hour, and then dropwise add 100 grams of vinylidene fluoride— Hexafluoropropylene copolymer dispersion (FKM emulsion L636, 30% solid content, purchased from Solvay SolexisS.P.A), high-speed stirring, add 0.2 grams of hydroxypropyl cellulose and dodecylbenzene 0.1 g of sodium sulfonate in 100 g of deionized water, and adjust the pH value to 6 with 20% sodium hydroxide solution. Raise the temperature to 75°C for 5 hours. After cooling, filter with a 200-mesh filter cloth and dry to obtain 118 grams of particles with an average particle diameter of 4.5 mm. Hereinafter referred to as fluoropolymer A.
Embodiment 2
[0035] In a 500ml four-necked bottle, add 60 grams of methyl methacrylate, 25 grams of butyl acrylate, 15 grams of methacrylic acid and 0.5 grams of azobisisobutylcyanide mixture, pre-react at 60 ° C for 1 hour, and then dropwise add 100 grams of partial Vinyl fluoride-hexafluoropropylene copolymer dispersion (FKM emulsion L636, 30% solid content, purchased from Solvay Solexis S.P.A), high-speed stirring, add 0.2 grams of hydroxypropyl cellulose dissolved in it, dodecane Add 0.1 g of sodium phenylsulfonate to 100 g of deionized water, and adjust the pH value to 6 with 20% sodium hydroxide solution. Raise the temperature to 75°C for 5 hours. After cooling, filter with a 200-mesh filter cloth and dry to obtain 107.8 grams of particles with an average particle diameter of 4.5 mm. Hereinafter referred to as fluoropolymer B.
Embodiment 3
[0037] In a 500ml four-necked bottle, add 70 grams of methyl methacrylate, 20 grams of butyl acrylate, 10 grams of acrylic acid and 0.5 grams of azobisisobutylcyanide mixture, pre-react at 60 ° C for 1 hour, and then dropwise add 100 grams of vinylidene fluoride - Hexafluoropropylene copolymer dispersion (FKM emulsion L636, 30% solid content, purchased from Solvay Solexis S.P.A), high-speed stirring, and adding 0.2 grams of hydroxypropyl cellulose and dodecylbenzene 0.1 g of sodium sulfonate in 100 g of deionized water, and adjust the pH value to 6 with 20% sodium hydroxide solution. Raise the temperature to 75°C for 5 hours. After cooling, filter with a 200-mesh filter cloth, and obtain 113 grams of particles with an average particle diameter of 4.5 mm after drying. Hereinafter referred to as fluoropolymer C.
