Embodiment 1
[0045] Embodiment 1: technical scheme of the present invention
[0046] Antifouling coating A2: 94% antifouling coating A1, 5% E44 epoxy resin (epoxy value 0.41~0.47mol / 100g), 1% thermoplastic acrylic resin (methyl methacrylate-ethyl acrylate- acrylamide copolymer).
Embodiment 2
[0047] Embodiment 2: technical scheme of the present invention
[0048] First prepare the polishing type acrylate zinc / copper resin that the present invention uses:
preparation example 1
[0050] In the reactor equipped with stirring, condensing device, dripping device, and thermometer, add 33.5% xylene and 10% propylene glycol monomethyl ether under stirring, add 5% methyl methacrylate, 20% Butyl acrylate, 20% zinc monomethacrylate, 10% acetylacetone, and 1.2% azobisisobutyronitrile were stirred and mixed to prepare a monomer solution. Continue to stir, raise the temperature to 100°C and keep it, add dropwise the prepared monomer solution, control the dropping speed, after 2 hours, add 0.3% azobisisobutyronitrile, control the temperature at 100°C, keep the temperature for 3 hours, and cool to get Polished zinc acrylic resin. The resin is water white and transparent, and its weight-average molecular weight measured by GPC is 4000-20000.
