自抛光防污涂层的水渗透特性及其对抛光速率的影响研究
Study on Water Penetration Characteristics of Self-Polishing Antifouling Coatings and Their Effect on Polishing Rates
摘要
Abstract
Antifouling coatings applied to the surface of marine facilities can significantly cut down on the economic losses caused by biofouling.Among them,self-polishing antifouling coatings have become the leading products in the antifouling coatings market for their good polishing performance and excel-lent antifouling effect.The permeation behavior of water in two acrylic silicone self-polishing antifouling coatings A1 and A2 was analyzed and compared by electrochemical impedance spectroscopy(EIS),and the polishing rates of the two coatings in 3.5%artificial seawater were measured by dynamic simulation tests.The EIS results demonstrated that the water penetration in both acrylic silicone self-polishing an-tifouling coatings followed the Fick diffusion pattern,which were then fitted to give a saturated volume percentage of water absorption approximately 11.5%for coating A1 and 20%for coating A2.According to dynamic simulations,the polishing rates in 3.5%artificial seawater was 0.15 μm/d for antifouling coat-ing A1 and 0.26 μm/d for coating A2.The higher saturated volume percentage of water absorption has a more favorable effect on the ability to hydrolyze of the silicone acrylate resin,which speeds up polishing.关键词
