无溶剂环氧输油气管内低表面处理防腐减阻涂料的研制

Development of Solvent-free Epoxy Anticorrosive Resistance-reducing Coatings for Invert Surface Treatment of Oil Pipes

以液态环氧树脂、稀释剂为基体树脂,以腰果壳液改性酚醛胺为固化剂,以复合铁钛粉、磷酸锌、氧化铁红、聚四氟乙烯、沉淀硫酸钡、陶瓷微珠等为填料,在多种功能助剂的配合下制备成无溶剂环氧输油气管内低表面处理防腐减阻涂料。集带锈带油、带湿涂装为一体,具有防腐、减阻、耐磨等特性。

With liquid epoxy resin and thinner as the base resin, cashew nut shell liquid modified phenolic aldehyde amine as the curing agent, and iron-titanium compound powder, zinc phosphate, red iron oxide, polytetrafluoroethylene, precipitated barium sulfate, ceramic micro-bead and so on as fillers, the solvent-free epoxy anticorrosive resistance-reducing coatings for treatment of invert surfhces of oil pipes were prepared with assistance of various functional additives. Integrating painting functions on rusty, oily and wet surfaces, the coatings had such properties as anticorrosion, resistance reducing, wear resistance and so on.
