Description

纳米硅碳改性石墨烯特种防腐涂料及其制备方法 技术领域
本发明涉及一种纳米硅碳改性石墨烯特种防腐涂料及其制备方法。
 背景技术
随着石油化工工业技术的不断进步，金属管道设备腐蚀的问题也越来越严重。中国每年因金属腐蚀带来的经济损失巨大，同时腐蚀也是制约石油化工工业发展的一个重要因素。尤其在采油及集输系统中的腐蚀中的油井腐蚀：油井腐蚀是指采出液和伴生气中含有的二氧化碳、硫化氢和采出水等有害成分造成的油水井油管、套管和井下工具的腐蚀。还有集输系统的腐蚀：当集输管线中运输的原油中含有较多的水且水中含有氧气、二氧化碳或硫酸盐还原菌时会在集输管线内部产生严重的电化学腐蚀。
近年来，油管的防腐蚀已引起国内外油田和防腐界的高度重视，相继形成使用耐蚀合金管材、涂渡层管材等系列防腐蚀措施。目前，石油管道内壁所使用的防腐涂料主要以双组份为主，性能指标能满足使用要求。但双组份涂料的活化期较短，加入固化剂后通常在2小时左右开始凝胶反应，造成施工使用不便，效率不高，且经常存在因固化剂加入时多时少导致涂层出现质量问题。
以AMF-Tubboscope和PO 公司为代表自20世纪80年代开始研究管道涂料，已经形成系列化油管单组份防腐涂料，销售量占国际市场的90%以上，且市场售价极高。目前，使用的单组份防腐涂料采用的也是传统的抗蚀原理，以阻止金属与腐蚀介质的接触，并利用涂层的耐蚀性、密封性、缓蚀性等性能来达到保护金属的目的。虽然能满足基本性能要求，但还是存在的下述问题，一是储存稳定性差，大部分常温放置3-6个月就开始反应增稠甚至胶化；二是交联密度不够漆膜的附着力一般，对液体介质的抗渗透性有限；三是抗冲击和耐磨性一般，耐温小于180℃，尤其在高温高压下容易导致涂层起泡和附着力下降；四是施工操作不便。
