环氧煤沥青冷缠带

The Cold Wrapping Tape of the Epoxy Coal Tar Anti-conrrosion Paint

回顾了环氧煤沥青涂料的应用实践,指出虽然该涂料有诸多优点,但因其固化反应受温度影响,质量不易保证等缺陷限制了使用。提出了一种新型防腐材料——环氧煤沥青冷缠带。它以涤纶无纺布为基材,将高环氧树脂含量的环氧煤沥青涂敷在基材上,用低温氧化、潮湿型树脂固化剂作底胶。使用冷缠带所形成的覆盖层具有机械强度高、粘结力大、化学性质稳定、电绝缘性能好等特点。同时还介绍了冷缠带的技术性能、施工方法、经济指标及适用范围。

The application practice of the epoxy coal tar anti-corrosion paint is reviewed. It is pointed out that the paint has some advantages in its performances,however,the quality of the final coatings is limited to a certain extent in its application due to the effect of temperature on the curing reaction. A new type of the cold wrapping tape of the epoxy coal tar anti-corrosion paint is introduced. The polyester non-woven are used as the base tape. The coating material is made of epoxy coal tar with high content of epoxy resin. The coating of cold wrapping tape is suitable for the curing under low temperature and high humidity environment. The coating has high mechanical strength,strong adhesive and chemical stability. The technical specifications, installing method and economical analysis of the new product as well as its applicability are introduced in the paper.
