【摘要】 为满足埋地输油管道外防护层大修的需要,研制了一种无溶剂环氧石油沥青重防腐蚀涂料.以环氧树脂作为主要成膜物质,加入石油沥青以解决与旧涂层搭接的问题.无溶剂环氧石油沥青重防腐蚀涂料具有无溶剂、固化时间短的特点,适于加热喷涂.同时还对施工方法进行了讨论.更多还原

【Abstract】 In order to suffice the need of coating’s rebuilding of buried oil pipiline, a kind of solvent-free heavy duty epoxy-asphalt coating has been developed. A type of the epoxy was selected as the main film-forming material. The bond strength between the new coating and old coating can be improved by the interfusion of as-phalt. This solvent-free coating has a short cure time. The application technology is also discussed in this article.更多还原
