摘要
环氧树脂涂层因其良好的附着力和优异的机械性能而广泛应用于材料表面防护领域。有机硅改性环氧树脂涂层可以在保留环氧树脂本身性能的同时,提高其韧性、疏水性、耐腐蚀性以及减摩抗磨等性能。本文首先从聚二甲基硅氧烷改性环氧树脂、硅烷偶联剂改性环氧树脂以及多面体低聚倍半硅氧烷(POSS)改性环氧树脂等方面综述了不同种类有机硅化学改性环氧树脂的已有研究情况,再结合环氧树脂纳米复合涂层的广泛应用,归纳总结了有机硅与纳米颗粒协同改性环氧树脂涂层在超疏水、防腐蚀以及减摩抗磨方面的最新研究进展及应用,深入探讨了有机硅在环氧树脂复合涂层中的作用机理。指出有机硅改性环氧树脂涂层的研究应聚焦在有机硅与纳米颗粒的协同作用以及多功能涂层的性能调控上。
Epoxy resin coatings are widely used in the field of material surface protection due to their good adhesion and excellent mechanical properties.Silicone⁃modified epoxy resin coatings can improve the toughness,hydrophobicity,corrosion resistance and anti⁃friction and anti⁃wear properties of epoxy resin while retaining its own properties.First,this article reviewed the previous research on the different types of sili⁃cone chemically modified epoxy resins,including polydimethylsiloxane⁃modified epoxy resin,silane coupling agent⁃modified epoxy resin and polyhedral oligomeric silsesquioxane(POSS)modified epoxy resin.Combined with the widespread application of epoxy resin nanocomposite coatings,this article summarized the latest research progress and applications of synergistic modification of epoxy resin coatings with silicone and nanoparticles in the fields of superhydrophobicity,corrosion resistance and friction reduction and wear resistance were summarized,and the mechanism of silicone in epoxy resin composite coatings was further explored.At last,this article pointed out that the research on silicone⁃mod⁃ified epoxy resin coatings should focus on the synergistic effect between silicone and nanoparticles,as well as the performance regulation of multifunctional coatings.
