摘　　要：为了解决斜拉桥平行钢丝索、悬索桥主缆索股锚固系统等桥梁结构的密封防腐问题,研究了一种低挥发含量的非硫化橡胶型阻蚀密封膏。该密封膏可长期保持柔软状态,不硬化、不干裂、低温性能优良,抗老化、抗盐雾和施工工艺性能良好,可望替代目前常用油脂在桥梁结构防腐领域获得广泛应用。This paper focuses on the development of a non-vulcanizable rubber-based anti corrosive sealing paste with low volatile content to seal and protect the parallel steel strands of cable stayed bridges and main cables of suspension bridges against corrosion. This sealing paste can remain permanent flexibility without stiffening or cracking, and has excellent low-temperature properties, perfect aging characteristics, good anti-salt-spray-corrosion capability and favorable workability. It is supposed to be an excellent choice to replace the now commonly-used oil grease and obtain extensive applications.
