The invention discloses a branched-point fracture type hyperbranched resin, and a method and application thereof. The branched-point fracture type hyperbranched resin is mainly prepared from the following components in parts by weight: 0-70 parts of vinyl antifouling functional monomer, 1-60 parts of bifunctional monomer, 0-90 parts of vinyl monomer, 1-20 parts of initiator, 0.5-10 parts of chain transfer agent and 50-150 parts of organic solvent. The branch point of the resin can be broken under the attack of seawater, and small molecular fragments which are easily absorbed by the environment are formed after the breaking, so that the pollution of marine micro-plastics can be effectively avoided. Meanwhile, the side chain silane ester bond/zinc ester bond/copper ester bond/betaine type zwitter-ion precursor can be hydrolyzed in seawater, and the hydrolysis rate of the material can be further accelerated by the cooperation of the side chain silane ester bond/zinc ester bond/copper ester bond/betaine type zwitter-ion precursor and the branch point fracture, so that the rapid polishing is realized, the problem of dependence of the traditional self-polishing material on the navigational speed is solved, and the static antifouling requirement of a sea area with large fouling pressure is met. |
