This invention relates to a fluorosilicone-modified acrylic resin and its preparation method, belonging to the field of polymer materials technology. The resin uses methyl methacrylate, butyl acrylate, and hydroxyethyl methacrylate as basic monomers. Fluorine is introduced through copolymerization with tridecafluorooctyl acrylate. A self-made doped silicone modifier is introduced via blending. The doped silicone modifier is modified by the ring-opening and ring-closing reaction of epichlorohydrin with the secondary amine structure of hexamethylcyclotrisilazane, grafting branched active epoxy groups. Subsequently, n-decylamine is used to open the ring with the grafted epoxy groups, introducing terminal long-chain alkyl modification. This modifier exhibits good compatibility with the acrylic polymer chain and acts as a support in the resin, reducing the shrinkage stress after curing and improving the impact resistance of the cured film. Simultaneously, the reduction in micro-shrinkage results in a film with higher gloss and fullness.
