A method for preparing a main
chain scission-type polysilyl (
meth)
acrylate resin and application thereof. The method comprises: a cyclic
monomer, vinyl
monomer and vinyl silyl ester
monomer are mixed in a
solvent at a formulation ratio, then added a composite initiator in a
mass percentage of 0.01-5% based on the total amount of the monomers, and reacted at a temperature of 25-150° C., and under the protection of
argon or
nitrogen gas, so as to prepare the main
chain scission-type polysilyl (
meth)
acrylate resin, wherein the monomers are consisted of 5-95% by
mass of cyclic monomer, 0-90% by
mass of vinyl monomer and 5-95% by mass of vinyl silyl ester monomer. The resulting resin can not only be hydrolyzed on the
side chain silyl ester segment under the effect of the sea water, but also occur
chain scission on the main chain
polyester segment under the effect of the
seawater, so as to solve the dependency of the traditional self-
polishing material on the sailing speed, effectively control the release of the antifouling agent at a
constant rate, ensure the active substance preserved on the
coating surface of the ships, and properly meet the antifouling requirements on the low sailing speed ships, submarines and off-
shore oil platform facilities.
