- 摘要： A UV-curable solvent-free antifouling coating formulated by a novel epoxy methacrylate-containing phthalazinone moiety with reactive diluents and photoinitiator and non-toxic N-vanillylnonanamide as antifoulant was prepared. First, the basic performance of the cured films obtained was evaluated using Chinese National Standards. This environmentally friendly antifouling coating has excellent physical properties, with a pencil hardness of above 5H, an adhesion of grade 1, impact strength above 45 cm, and good resistance to alkali and salt but not acid. Then antifouling evaluation was carried out by the leaching rate of antifoulant, and by immersing samples in natural sea water, respectively. The results from the leaching rate of N-vanillylnonanamide from the antifouling coating shows that the release rate of 45 mu g/m(2) day of the coating with 15% antifoulant is steady after a slight decrease, and this coating can effectively prevent marine organisms attaching for 6 months, which is also evidenced by field tests in natural sea water.
