The invention discloses a kind of preparation method and application of main chain fracture type polyacrylic acid silane ester resin, the method is mixed in a solvent by proportioning cyclic monomer, vinyl monomer, vinyl silanes ester monomer, then adding monomer total amount mass percent is the composite initiator of 0.01 ~ 5%, be 25 ~ 150 DEG C in temperature, reaction preparation under the condition of argon gas or nitrogen protection; By percentage to the quality, set of monomers becomes: cyclic monomer 5 ~ 95%, vinyl monomer 0 ~ 90% and vinyl silanes ester 5 ~ 95%; The resin that the present invention obtains is except side chain silicon ester can be hydrolyzed under the effect of seawater, also can chain rupture be there is in main chain polyester segment under the effect of seawater, solve tradition from the dependency of polishing material to the speed of a ship or plane, Effective Regulation stain control agent discharges with constant rate of speed, ensure that the maintenance of active substance on coating for watercraft surface, well meet the boats and ships of the low speed of a ship or plane, the antifouling requirement of submarine and offshore production platform facility. |
