【摘要】:近些年來,隨著石油化工產(chǎn)業(yè)的快速發(fā)展,石油儲罐和運輸管道用量不斷加大,儲罐和管道因腐蝕導(dǎo)致油品泄露以及石油在儲存和運輸過程中產(chǎn)生的靜電荷引起的爆炸或火災(zāi)等事故頻有發(fā)生,因此研發(fā)出兼具導(dǎo)靜電和防腐功能的涂料為解決以上問題提供了新途徑。本文選取具有機械性能好、耐腐蝕性強、抗蠕變性能佳的聚醚砜樹脂和摩擦系數(shù)小、化學(xué)穩(wěn)定性高、不粘性好的聚四氟乙烯樹脂作為涂層的基體樹脂,,探索了添加不同碳系導(dǎo)電填料、不同方法處理的碳納米管復(fù)合導(dǎo)電填料、不同含量聚四氟乙烯樹脂、不同含量玻璃鱗片和不同含量三聚磷酸鋁對聚醚砜-聚四氟乙烯涂料性能的影響,通過不斷的篩選和深入的研究,最終成功制備了具有優(yōu)異性能的抗靜電防腐涂料。 1.制備了不同含量碳納米管、石墨、炭黑、碳纖維四種碳系導(dǎo)電填料的聚醚砜-聚四氟乙烯涂層,分別探索了不同含量的四種導(dǎo)電填料對涂層性能的影響,并優(yōu)化出四種抗靜電涂層的最佳導(dǎo)電填料含量;通過對比這四種涂層性能,從中選出綜合性能最好的碳納米管/聚醚砜-聚四氟乙烯涂層進(jìn)行下一步研究。 2.由于碳納米管的獨特結(jié)構(gòu),導(dǎo)致其容易發(fā)生團聚,很難在樹脂中較好的分散,影響涂層的性能。為此,我們選用不同方法處理后的可分散性碳納米管導(dǎo)電填料、碳納米管鈦白導(dǎo)電復(fù)合填料、碳納米管云母導(dǎo)電復(fù)合填料制備了三種抗靜電涂層,并研究不同含量的三種碳納米管對涂層性能的影響,優(yōu)化出三種抗靜電涂層的最佳碳納米管含量;對比這三種涂層性能,從中選出綜合性能最好的可分散性碳納米管/聚醚砜-聚四氟乙烯涂層進(jìn)行下一步研究。 3.為了進(jìn)一步研究聚四氟乙烯樹脂對可分散性碳納米管/聚醚砜-聚四氟乙烯涂層的性能影響,分別制備了不同含量聚四氟乙烯的可分散性碳納米管/聚醚砜涂層,發(fā)現(xiàn)聚醚砜樹脂:聚四氟乙烯樹脂=8:3(質(zhì)量比)的涂層綜合性能最好。 4.為了進(jìn)一步增強可分散性碳納米管/聚醚砜-聚四氟乙烯抗靜電涂層(聚醚砜樹脂:聚四氟乙烯樹脂=8:3)的防腐性能,分別向該涂料中加入不同含量玻璃鱗片和三聚磷酸鋁防腐填料,制備了兩種可分散性碳納米管/聚醚砜-聚四氟乙烯抗靜電防腐涂層,發(fā)現(xiàn)玻璃鱗片含量為10%和三聚磷酸鋁含量為20%的這兩種涂層綜合性能最好,涂層抗靜電性好,機械性能強,附著力0級,接觸角在110°左右,熱穩(wěn)定性好,可耐鹽霧720h以上。
[Abstract]:In recent years, with the rapid development of petrochemical industry, the consumption of oil storage tanks and transportation pipelines has been increasing. Accidents such as oil leaks caused by corrosion in storage tanks and pipelines and explosions or fires caused by static charges generated during storage and transportation occur frequently. Therefore, it provides a new way to solve the above problems by developing a coating with both electrostatic conductivity and anticorrosion function. In this paper, polyethersulfone resin with good mechanical properties, corrosion resistance and creep resistance is chosen as the base resin of the coating, which has low friction coefficient, high chemical stability and good non-viscosity. The carbon nanotube composite conductive filler with different carbon series conductive filler and different content of polytetrafluoroethylene resin was explored. The effects of different contents of glass scales and aluminum tripolyphosphate on the properties of polyethersulfone-PTFE coatings were studied and the antistatic anticorrosive coatings with excellent properties were successfully prepared by continuous screening and further study. 1. Polyethersulfone polytetrafluoroethylene (PTFE) coatings with different contents of carbon nanotubes, graphite, carbon black and carbon fiber were prepared. The best conductive filler content of the four antistatic coatings was optimized and the best carbon nanotube / polyethersulfone PTFE coating was selected for further study by comparing the properties of the four coatings. 2. Because of the unique structure of carbon nanotubes, it is easy to be agglomerated, and it is difficult to disperse in the resin, which affects the properties of the coating. For this reason, three kinds of antistatic coatings were prepared by different methods, such as dispersible carbon nanotube conductive filler, carbon nanotube titanium dioxide conductive composite filler and carbon nanotube mica conductive composite filler. The effects of three kinds of carbon nanotubes with different contents on the properties of the coatings were studied to optimize the optimum content of the three kinds of antistatic coatings. The best dispersible carbon nanotubes / polyethersulfone-PTFE coatings were selected for further study. 3. In order to further study the effect of PTFE resin on the properties of dispersible carbon nanotubes / polyethersulfone-polytetrafluoroethylene coatings, the dispersible carbon nanotubes / polyethersulfone coatings with different content of PTFE were prepared. It was found that the polyethersulfone resin: PTFE resin 8: 3 (mass ratio) had the best comprehensive properties. 4. In order to further enhance the anticorrosive properties of dispersible carbon nanotubes / polyethersulfone-polytetrafluoroethylene antistatic coatings (polyethersulfone resin: polytetrafluoroethylene resin / 8: 3), Two kinds of dispersible carbon nanotubes / polyethersulfone-polytetrafluoroethylene antistatic anticorrosive coatings were prepared by adding different contents of glass scales and aluminum tripolyphosphate fillers into the coating. It was found that the two coatings with 10% glass scales and 20% aluminum tripolyphosphate had the best comprehensive properties. The coatings had good antistatic property, strong mechanical properties, good adhesion, contact angle about 110 擄, good thermal stability and resistance to salt spray for more than 720h.
