摘要
电弧燃烧会破坏绝缘子的超疏水涂层,通过掺杂高导热纳米颗粒可以提高涂层的耐电蚀性能。本研究采用几种丙烯酸单体共聚制备氟碳树脂,然后掺杂改性纳米SiO2和纳米BN颗粒,制备得到不同纳米BN掺杂量的氟碳树脂超疏水涂层。对涂层的疏水性、耐候性、导热性等进行测试,研究纳米BN掺杂量对涂层性能的影响。结果表明:超疏水涂层的静态接触角平均值达163°,具有优异的超疏水性和耐候性;当纳米BN质量分数为40%时,涂层的导热系数提高至0.35 W/(m·K),同时具有良好的耐电蚀性能。
Arc burning would destroy the superhydrophobic coatings of insulator, and the electrical erosion resistance of coatings can be improved by doping nanoparticles with high thermal conductivity. In this research, a fluorocarbon resin was prepared by copolymerization using several kinds of acrylic monomers, and then superhydrophobic fluorocarbon resin coating with different content of nano-BN was obtained by doping modified nano-SiO2 and nano-BN. The hydrophobicity, weatherability, and thermal conductivity of the coatings was tested, and the effect of nano-BN content on the performance of the coatings was studied. The results show that the average static contact angle of the superhydrophobic coatings reaches 163°, and the coatings have excellent super-hydrophobicity and weatherability. When the mass fraction of nano-BN is 40%, the thermal conductivity of the coatings increases to 0.35 W/(m·K),and the coatings have good electrical erosion resistance.
