Description

一种新型超能纳米五防粉末涂料
技术领域：
本发明涉及油气田开发油井及地面采出油管防腐涂料，具体是一种新型超能纳米五防粉末涂料。
背景技术：
油田油气田开发过程中，井下采油管、地面采出油管结、结蜡、腐蚀、偏磨等问题突出，严重影响了油井采油量及地面系统输油效率，而清垢、清腊又造成采油成本大幅度增加。特别是，采油后期三元复合驱驱油技术的应用，结垢问题更加突出。油田在用粉末涂料由于耐温、耐磨效果差，应用中涂层易发生脱落、失效，达不到长期防腐、防蜡、防垢、防偏磨的效果。
发明内容：
本发明在于克服背景技术中存在的问题，提供一种新型超能纳米五防粉末涂料。该网络互穿纳米超微细防腐防蜡防垢耐高温耐磨粉末涂料具有防腐、防腊、防垢、耐磨、耐高温多重功能，可在温度最高达到150℃油田油水介质中长期使用，能够长效耐高温防腐蚀耐磨损，并有效节约清腊、清垢成本。
本发明技术方案：该网络互穿纳米超微细防腐防蜡防垢耐高温耐磨粉末涂料，其组分及配比按质量百分比如下：
新型超能纳米五防粉末涂料包括下列各组分，各组分及配比按质量百分比如下：TPNE1601三官能团环氧树脂5％-10％，环氧树脂E2030％-40％，酰肼树脂10％-20％；脲类树脂1％-5％；纳米耐磨预混料EAIEN-115％-30％，低表面能超细蜡粉预混料EAIEN-21％-5％，绢云母1-5％、流平剂5％-10％、增光剂1％-5％、附着力促进剂LTH 1％-5％；低表面能超细蜡粉预混料EAIEN-2的粒度是1500目；纳米耐磨预混料EAIEN-1的粒度为50－150nm。
本发明选择能够形成网络互穿结构的成膜物质TPNE1601三官能团环氧树脂和环氧树脂E20和固化剂酰肼树脂和脲类树脂，形成网络大分子的空间结构，能够有效提高粉末涂料耐高温、耐磨效果；加入纳米级耐磨预混合助剂，进一步提高耐磨效果的同时，具有较高的韧性；加入低表面能超微细蜡粉预混合助剂，有效提高其防垢、防蜡效果；加入能够提高粉末涂料附着和表观性能的流平剂、附着力促进剂等功能助剂，利用已有的粉末涂料制备设备，经过粉碎、挤出、压片、破碎、磨粉，形成功能型重防腐粉末涂料。所述纳米耐磨预混料EAIEN-1为纳米SiO2、纳米碳化硅、纳米Al2O3等纳米耐磨粒子经超高速混合工艺预混合而成粒度为50－150nm，购自黑龙江易爱蒽新材料科技发展有限公司；所述低表面能超细蜡粉预混料EAIEN-2为超微细聚四氟微蜡粉、超微细聚乙烯微蜡粉等蜡粉经高温熔融混合粒度是1500目，冷却破碎等工艺预混合而成，购自黑龙江易爱蒽新材料科技发展有限公司。三官能团环氧树脂TPNE1601购自上海华谊树脂有限公司；附着力促进剂LTH购自上海广凌化工有限公司。酰肼树脂为间苯二甲酸二酰肼ADH购自南京市利源化工有限公司；脲类树脂为二甲基脲UREA购自南京市利源化工有限公司。
为了实现涂料在150℃油田油水介质长期使用，要求涂料成膜物质具有较好的耐温性能、耐磨性能和化学稳定性能。本发明采用TPNE1601三官能团环氧树脂、环氧树脂E20、酰肼树脂、脲类树脂树脂，经过高温熔融网络互穿反应固化。为进一步提高涂料体系的耐磨性能，本发明根据粒子粒度分布对耐磨性的影响特征，采用纳米级耐磨预混料EAIEN-1作为粉末涂料的耐磨功能助剂。为增强粉末涂料具备防垢、防蜡的功能，本发明采用与超细蜡粉预混料EAIEN-2作为粉末涂料防垢防蜡功能助剂。
本发明与上述背景技术相比较，具有如下有益效果：该新型超能纳米五防粉末涂料，具有防腐、防垢、防蜡、耐温、耐磨特性，即降低了管道的防腐技术成本，又降低了管道清垢、清腊等作业成本，具有显著的经济效益和社会效益。
