NOVELTY - A self-polishing antifouling fluorosilicone acrylate resin (I) is obtained by forming network structure by reacting fluorosilicone acrylate monomer with acrylate monomer, hydrolyzing resin molecule in ester group, obtaining fluorine-containing siloxane, breaking the network structure, degrading short-chain fragment, such that molecular layer in contact with water produces self-polishing effect, and regulating polishing rate.    USE - Self-polishing antifouling fluorosilicone acrylate resin is used for preventing ocean pollution.    ADVANTAGE - The self-polishing antifouling fluorosilicone acrylate resin is prepared by simple, environmentally-friendly and easy method, using readily available raw materials.    DETAILED DESCRIPTION - A self-polishing antifouling fluorosilicone acrylate resin of formula (I) is obtained by forming network structure by reacting fluorosilicone acrylate monomer with acrylate monomer containing R3 and R4 groups, hydrolyzing resin molecule in ester group, obtaining fluorine-containing siloxane, breaking the network structure, degrading short-chain fragment, such that molecular layer in contact with water produces self-polishing effect, and regulating polishing rate by adjusting monomer ratio and type of R1-R4 group.    R3,R4=1-20C linear or branched alkyl or benzyl containing linear or branched alkyl;    R1=H or group of formula (i);    m=0-10;    R2=group of formula (ii);    n=0-10;    X=H or F;and    q,p=1-50.    An INDEPENDENT CLAIM is included for preparation of self-polishing antifouling fluorosilicone acrylate resin, which involves adding fluorosilicone acrylate monomer of formula (II), acrylate monomer, azobisisobutyronitrile and toluene to a reactor in weight ratio of 2:6-10:0.05-0.1:30-50, at 80-90 degrees C, stirring for 3-8 hours, and obtaining transparent self-polishing antifouling fluorosilicone acrylate resin. The fluorosilicone acrylate monomer is acrylic monomer containing fluorosilicone group. The molecular structure comprises two acrylates and one fluorine-containing siloxane. The fluorosilicone acrylate monomer is prepared by reacting R1 group-containing acrylic acid with potassium hydroxide, obtaining R1 group-containing potassium acrylate of formula: R1-C(=CH2)-C(=O)-OK (III), adding the resultant product to a reactor, adding toluene as solvent and 18-crown-6 as catalyst, reacting in water bath at 25-60 degrees C, mixing the resultant product with methyldichlorosilane containing R2 group, and toluene, reacting, and stirring for 12-48 hours.
