[0034] Step 1: Preparation of organic fluorine modified acrylic resin
[0035] First, MMA, BA, β-HEA, AA, and FMA are mixed in proportions, and uniformly stirred at room temperature to obtain a pre-mixed monomer. The mass fractions of the monomers are respectively: 30-35%, 22-28%, 10-16%, 15-19%, 3-12%; secondly, the initiator AIBN is mixed with the solvent xylene to obtain a mixed solvent, the mass of AIBN The fraction is 1.2-5.5%; finally, under the protection of N2, the pre-mixed monomers and mixed solvents prepared above are added to the reaction vessel at a uniform speed and dropwise at a mass ratio of 7:3 to 6:4. The entire reaction temperature is controlled at 55°C to 85°C, the reaction time is 2 to 5 hours, the reaction is completed, and the temperature is naturally lowered to obtain the organic fluorine modified acrylic resin.
[0036] Step 2: Preparation of silicone
[0037] First, ethyl orthosilicate (TEOS), absolute ethanol, hydrochloric acid, and deionized water are mi...
