用于舰船防污涂料的环氧甲萘醌微胶囊的性能调控

Performance adjustment of 2,3-Epoxy-2-methyl-1,4-naphthoquinone Microcapsule

摘要:

该文以聚丙烯酸酯为囊壁，环氧甲萘醌为囊芯制备了环氧甲萘醌微胶囊，并将其应用于舰船防污涂料中。采用透射电镜(TEM) 和纳米粒度仪对微胶囊形貌进行表征。研究了微胶囊核壳质量比对涂料中环氧甲萘醌渗出量及涂料防污效果的影响。结果表明，制备的环氧甲萘醌微胶囊平均粒径约为323.5nm。环氧甲萘醌微胶囊的核壳质量比为1:7时，制备的涂膜中环氧甲萘醌的释放速率最平稳，涂层防污效果最好。该类微胶囊的研究，为获得使用寿命长、毒性小、价格低廉的舰船防污涂料提供了新途径和新思路。

Abstract:

In this work, acrylic emulsion was chosen as the shell material to prepare 2,3-epoxy-2-methyl-1,4-naphthoquinone (ME) microcapsules. Transmission electron microscopy (TEM) and nano-particle size analyzer were used to characterize 2,3-epoxy-2-methyl-1,4-naphthoquinone microcapsules. The results showed that the average particle size of ME microcapsules (core-shell mass ratio was 1:7) was 323.5nm, the release rate of ME fom the coating film prepared using it was steady and the antifouling property of the coating film was excellent.
