Connecting paint matched with low-surface-energy antifouling paint and preparation method and application thereof

The invention relates to the technical field of marine antifouling coatings, and discloses connecting paint matched with low-surface-energy antifouling paint and a preparation method and application of the connecting paint. The connecting paint comprises a component I, a component II and a component III, the component I comprises epoxy resin; the component II comprises polyamino silicon resin and a silane coupling agent without epoxy groups; and the component III comprises dihydroxy-terminated silicone oil. According to the present invention, through the design of the whole connecting paint system, the good compatibility between the connecting paint and the primer can be provided, and the sufficient interface bonding can be achieved between the connecting coating and the bottom coating and between the connecting coating and the surface coating so as to substantially improve the interlayer adhesion in the antifouling coating, such that the antifouling coating does not easily blister or shed after the long-time
