摘　　要：管道防腐层大修材料直接影响大修后防腐层的质量。通过筛选适当的环氧树脂、固化剂、活性稀释剂、玻璃纤维布和体质颜料等,研制出一种常温固化的管道防腐层大修防腐材料——无溶剂环氧玻璃钢。测试结果表明,该材料具有良好的机械性能、耐化学介质浸泡性能和优异的抗阴极剥离性能,可以提高老化管线的防腐性能及强度。The pipeline anticorrosion coatings overhauled materials will directly influence on the quality of the anticorrosion coatings after overhaul. Through choosing proper epoxy resin, curing agent, reactive diluents, glass fabrics and pigments and fillers, a kind of air - dried pipeline anticorrosion coatings as overhauled materials--solventless epoxy FRP was developed. The result indicates that this material shows good mechanical property, chemical resistance and good resistance to cathod separation, which can improve anticorrosion property and strength of aged piplines.
