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.

Abstract

The invention relates to the field of anti-fouling coating materials, in particular to an anti-fouling coating material with excellent compatibility. The anti-fouling coating material with excellent compatibility contains liquid bisphenol A epoxy resin, polished acrylic resin, at least two thermoplastic resins for a coating film-forming material, at least two antifouling agents, at least two pigments and fillers, at least two solvents and at least two additives. With the adoption of the anti-fouling coating material with excellent compatibility, the excellent compatibility between a new/old anti-corrosion coating layer and an old antifouling coating layer can be provided, a connecting layer cannot be a coating layer necessary to be coated any more, the processes of coating are reduced, and excellent attachment and antifouling performances are shown after the long-term application of the anti-fouling coating material.

Description

technical field [0001] The invention relates to the field of antifouling paint, in particular to an antifouling paint with good compatibility and its application. Background technique [0002] Human beings have been facing the problem of marine biofouling since they exploited and developed the ocean. Marine biofouling will increase the weight of underwater structures and water flow resistance, resulting in serious economic losses, and even damage structures, leading to safety accidents. For safety and benefit, the common practice is to apply marine antifouling paint. In order to adapt to the updated environmental regulations, the antifouling paint system containing organic tin and DDT has been replaced. At present, mature products such as tin-free self-polishing antifouling coatings and low surface energy antifouling coatings have been introduced to the market one after another, and have achieved good results. However, these two types of products have little tolerance to ...
