石墨环氧抗静电涂料在高硫原油中的电性能和耐蚀性
Conductive Property and Corrosion Resistance of Graphite Epoxide Resin Anti-static Paints in High-sulfur Crude Oil
摘 要
针对高硫原油腐蚀严重的实际,选用环氧树脂为成膜物,填充石墨制备抗静电耐蚀涂料.采用静态浸渍法研究了石墨含量和硫浓度对涂料导电性、耐蚀性的影响.结果表明,室温下,在环氧树脂中添加35%的石墨制成的涂料可达到抗静电和耐蚀的要求;当温度为50～70 ℃时,石墨加入量为45%时耐蚀性较好.原油中硫含量变化对涂料耐蚀性影响较小.

Abstract
An anti-static and corrosion-resistant paint with epoxide resin as film forming matter and graphite powder as carrier was prepared to solve the corrosion problem of high-sulfur crude oil.The effects of graphite content and sulfur concentration on the conductive property and corrosion resistance were studied by static immersion method.The results showed that the corrosion resistance and the conductivity could meet the requirements when graphite content was 35% at room-temperature.When temperature was 50～70 ℃,corrosion resistance was fairly good when graphite content was 45%.The effect of sulfur concentration on the corrosion resistance of anti-static paints was small.
