Description
技术领域
本发明属于海洋防腐材料技术领域,具体涉及海洋钢结构长效防护多层环氧重防腐涂层及制备方法。
背景技术
近年来,随着海洋开发的推进,各种已建、在建及规划建设的海上勘测平台、采油平台、海上集油气管道、船舶、港口码头、跨海桥梁等海洋工程如雨后春笋出现,迫切需要海洋防腐性能更好、服役寿命更长的重防腐涂层技术。目前主要采用重防腐涂料对海洋钢结构进行保护,主要有环氧、聚酯、聚氨酯、醇酸树脂、酚醛树脂、氟碳树脂、过氯乙烯树脂、氯化橡胶、氯化聚乙烯等多种涂层应用于海洋防腐蚀工程中。中国专利200810190125.X介绍了一种混凝土结构重防腐纳米复合涂层及防护方法,涂层由纳米改性环氧封闭涂料、纳米改性环氧云铁中间漆及纳米改性含氟聚氨酯等面漆组成,比传统防腐寿命有所提高。海洋重防腐涂层与金属界面间的结合力和耐候性是影响涂层服役寿命的关键因素,但以上问题在现有专利和公开文献中仍没有得到有效的解决。因此,研制开发一种海洋钢结构长效防护涂层,使其具有优异结合力,良好耐候性,卓越防腐性能,超长服役寿命,且工艺简单实用是海洋工程防腐的迫切需要。
发明内容
本发明的目的在于提供海洋钢结构长效防护多层环氧重防腐涂层及制备方法,该多层环氧重防腐涂层具有更加优异的耐腐蚀性能,耐酸碱以及耐盐雾腐蚀能力显著提升;并且具有更优的抗生物污染能力,延长使用寿命。
本发明为实现上述目的所采取的技术方案为:
一种海洋钢结构长效防护多层环氧重防腐涂层,包含:
环氧基涂层,涂布于基底表面,厚度为15~160μm;
无溶剂环氧基涂层,涂布于环氧基涂层表面,厚度为120~400μm;
有机硅基涂层,涂布于无溶剂环氧基涂层表面,厚度为100~400μm。本发明设计构建了多层涂层结构,能够协同增强涂层的综合性能。其中,底层环氧基涂层,其涂料组分中包含多种活性官能团,可与金属表面羟基发生化学键合,表现出优异的结合能力;中间采用无溶剂环氧树脂,涂料中采用氧化石墨烯与环氧树脂等复配使用,发挥石墨烯优良的阻隔性能,同时增强涂层的交联性能,致密性好;表面层采用有机硅基涂层进行封闭,具有更低的表面能,表现出优异的抗生物污染性能。多层结构复合得到的防腐涂层具有优异的抗渗透性,耐酸碱腐蚀以及耐盐雾腐蚀性能明显提升,并且与基底之间具有优异的结合性能,防护性能好、使用寿命长,应用价值高。
进一步的,无溶剂环氧基涂层用涂料组分包括双酚F型环氧树脂和氧化石墨烯。
进一步的,有机硅基涂层用涂料组分包括改性硅氧烷聚合物;上述改性硅氧烷聚合物由7-羟基-6-甲氧基-3,4-二氢异喹啉与甲基丙烯酰键连的单体、3-(甲基丙烯酰氧)丙基三乙氧基硅烷和N-乙烯基吡咯烷酮聚合得到。本发明在有机硅基涂层用涂料组分内加入7-羟基-6-甲氧基-3,4-二氢异喹啉改性硅氧烷聚合物,制得的有机硅基涂层具有更佳的抗生物污染能力,并且与其它组分协同复配,进一步增强了多层环氧重防腐涂层的耐酸碱腐蚀以及耐盐雾性能,延长其使用寿命。其原因可能在于,采用7-羟基-6-甲氧基-3,4-二氢异喹啉对有机硅聚合物进行改性,在其链结构中引入新型结构单体,可能通过分子间作用力等使得有机硅网络结构发生重构,形成的涂层表现出更低的表面能,其防生物污染能力得到增强;同时,重构后涂层的网络结构可能更加均匀、紧密,使得防腐涂层具有更优的耐腐蚀性能。
改性硅氧烷聚合物,其分子量为20~40万。
上述改性硅氧烷聚合物的制备方法,包括:

进一步优选地,环氧基涂层的厚度为40~100μm。

进一步的,无溶剂环氧涂料制备方法,包括:取异佛尔酮二异氰酸酯、对苯二酚混合,氮气条件下升温至40~50℃,缓慢滴加丙烯酸羟乙酯,反应2~3h;然后加入双酚F型环氧树脂、丙烯酸、二月桂酸二丁基锡和氧化石墨烯,搅拌均匀,升温至65~75℃反应3~5h,之后加入苄基三乙基氯化铵和反丁烯二酸,升温至100~120℃,反应2~4h后降温至70~80℃,加入苯乙烯混合均匀得到无溶剂环氧涂料。
进一步的优选地,无溶剂环氧基涂层的厚度为160~250μm。
进一步的,有机硅涂料组分包括,按照重量份计,10~20份双羟基封端聚二甲基硅氧烷,1.5~5份改性硅氧烷聚合物,0.1~0.3份二月桂酸二丁基锡,8~15份四氢呋喃。

优选地,氧化石墨烯有DMF的固液比为2~3mg:1mL;乙基葫芦巴内酯与氧化石墨烯的质量比为2 ~3:1;DCC、DMAP与乙基葫芦巴内酯的摩尔比为1.1~1.4:0.1~0.2:1。
本发明的又一目的在于,提供了上述海洋钢结构长效防护多层环氧重防腐涂层在增强海洋钢结构耐酸碱腐蚀和耐盐雾腐蚀性能中的用途。
相比于现有技术,本发明具有如下有益效果:
本发明设计构建了多层涂层结构,复合得到的防腐涂层具有优异的抗渗透性,耐酸碱腐蚀以及耐盐雾腐蚀性能明显提升,并且与基底之间具有优异的结合性能,防护性能好、使用寿命长,应用价值高。本发明在有机硅基涂层用涂料组分内加入7-羟基-6-甲氧基-3,4-二氢异喹啉改性硅氧烷聚合物,制得的有机硅基涂层表现出更佳的抗生物污染能力,并且与其它组分协同复配,进一步增强多层环氧重防腐涂层的耐酸碱腐蚀以及耐盐雾性能。同时,本发明采用乙基葫芦巴内酯酯化改性氧化石墨烯,再与环氧树脂能复配使用,应用于防腐涂层的制备工艺中,能够进一步增强多层环氧重防腐涂层的耐腐蚀性,其耐酸碱腐蚀以及耐盐雾腐蚀能力进一步提升。
