Preparation method of room-temperature curing type F-Si self-cleaning anticorrosive paint

The invention relates to the technical field of anticorrosive coatings, and discloses a preparation method of a room-temperature cured F-Si self-cleaning anticorrosive coating, which comprises the following steps: 1, carrying out free radical copolymerization on a fluorine monomer, a silicon monomer, an acrylic monomer, a hydroxyethyl methylacrylate monomer, an initiator, an organic acid and a solvent to obtain a copolymer; 2, introducing a long-chain fluoroalkyl structure into the polymer; and 3, crosslinking with a TEOS curing agent to obtain the F-Si coating. Vinyl siloxane, a fluorine-containing monomer, an acrylic acid type monomer and hydroxyethyl methylacrylate are used as monomers, a unique long-chain fluoroalkyl structure is introduced into a polymer, and fluorine-containing organic silicon resin is formed through free radical solution polymerization; and cross-linking the synthesized F-Si resin with a TEOS curing agent to prepare the F-Si coating. The coating prepared by the invention has hydrophobi
