| 目的 提高硼酚醛环氧涂料的耐腐蚀性、表面接触角、粘结强度及耐磨性等。 方法 用纳米二氧化钛浓缩浆改性硼酚醛环氧涂料,制备耐温耐蚀型纳米复合涂料。 通过高温高硫原油浸泡试验评价纳米复合涂层的耐腐蚀性能,通过扫描电镜观察、表面接触角测试、粘结强度测试和耐磨性测试等手段分析纳米二氧化钛浓缩浆对涂层性能的影响。 结果 硼酚醛环氧纳米复合涂层在 100 ℃ 高硫原油腐蚀浸泡后,微观上没有出现腐蚀坑和裂纹。 添加 2% 纳米二氧化钛浓缩浆的硼酚醛环氧纳米复合涂层与未添加纳米粒子的硼酚醛环氧涂层相比,抗渗性与耐磨性有所提高。 720 h 腐蚀试验后,纳米复合涂料的粘结强度由试验前的 7. 7 MPa 降低至 6. 9 MPa。 腐蚀过程中,其表面接触角比非纳米涂层高 4° ~ 7°。 结论 高温高硫原油没有破坏硼酚醛环氧纳米复合涂层的形貌结构、粘结强度和耐磨性。 添加 2% 纳米二氧化钛提高了涂层的抗渗透性和表面接触角。 |

| Objective To improve the corrosion resistance, surface contact angle, bonding strength and abrasion resistance of boron phenolic-epoxy coatings. Methods In this paper, boron phenolic-epoxy coatings were modified by TiO2 nano-concentrates, and composite nano-coatings with resistance against high temperature and corrosion were prepared in the study. The corrosion resistance of nano-coatings was evaluated by immersion test in high-sulfur crude oil. The SEM morphology observation and measurement of surface contact angle, bonding strength and abrasion resistance were used to investigate the effect of TiO2 nano-concentrates on the properties of boron phenolic-epoxy coatings. Results From the SEM observation, no defects were found on the surface of boron phenolic-epoxy nano-coatings after exposure to 100 ℃ high-sulfur crude oil. 2% TiO2 nano-concentrates improved the permeation resistance and abrasion resistance of nano-coatings. The bonding strength of composite nano-coating only decreased from 7. 7 MPa to 6. 9 MPa after the corrosion test, and the surface contact angle of nano-coating was 4° ~ 7° higher than that of coating without nano-particles during the 720 h corrosion test. Conclusion The morphological structure, bonding strength and abrasion resistance of boron phenolic-epoxy nano-coatings were not damaged by 100 ℃ high-sulfur crude oil. 2% TiO2 nano-concentrates increased the permeation resistance and surface contact angle of the composite nano-coating. |
