The present invention relates to self-polishing marine antifouling paint compositions comprising rosin or rosin equivalent(s), optionally fibres, and one or more polymeric flexibilizer component(s). The rosin part of the paint preferably comprises ammonium or metal salts of rosin and/or rosin qualities having a low content of conjugated double bonds, i.e. a low degree of unsaturation. The non-crystalline flexibiliser components have a glass transition temperature, Tg, in the range of -45 to 25°C and are preferably selected from poly(meth)acrylates, polyacrylamides, copolymers and terpolymers thereof, acrylamide resins, acrylic acrylamide resins, polyvinyl ethers, polyvinyl esters, polyesters, polyoxy-C1-5-alkylenes, polyurethanes, and epoxy esters. The fibers are preferably natural or synthetic inorganic or organic fibres or metal fibres. The paints have improved mechanical properties such as strength and resistance towards wheathering.
本发明涉及自抛光船用防污漆组合物,该组合物包括松香或松香等同物、可选的纤维和一种或多种聚合物柔顺剂成分。涂料中的松香部分最好包括共轭双键含量低(即不饱和度低)的松香和/或松香质量的铵盐或金属盐。非结晶柔顺剂成分的玻璃化转变温度 Tg 在 -45 至 25°C 之间,最好选自聚(甲基)丙烯酸酯、聚丙烯酰胺、其共聚物和三元共聚物、丙烯酰胺树脂、丙烯酸丙烯酰胺树脂、聚乙烯醇醚、聚乙烯醇酯、聚酯、聚氧-C1-5-烯烃、聚氨酯和环氧酯。纤维最好是天然或合成的无机或有机纤维或金属纤维。这些涂料具有更好的机械性能,如强度和抗粉化性能。
