The invention discloses a steel rail welding seam ultrasonic flaw detection coupling agent, which relates to the technical field of steel rail detection, and comprises, by mass, 10-40% of a solvent, 1-3% of a gelling agent, 1-3% of a colloid stabilizer, 0.5-1.5% of an organic sulfur compound, 0.02-2% of an antirust agent, 0.01-0.5% of an auxiliary agent, and the balance of water. According to the ultrasonic flaw detection coupling agent for the steel rail welding seam, the nonionic surfactant is used as an auxiliary agent and has good hydrophilicity and decontamination capacity, so that the coupling agent can be more easily wetted and cleaned by water when encountering rainwater, meanwhile, the adhesive force between the coupling agent and the surface of a workpiece can be reduced, volatilization is facilitated, and corrosion resistance and oxidation resistance are achieved; meanwhile, the performance of the coupling agent is improved, the lubricity of the coupling agent is improved, the surface tension is reduced, the effect of the coupling agent in practical application is improved, and the coupling agent has high reliability.

    本发明公开了一种钢轨焊缝超声波探伤耦合剂,涉及钢轨检测技术领域,按质量百分比计,耦合剂,包括:溶剂10~40%、胶凝剂1~3%、胶体稳定剂1~3%、有机硫化合物0.5~1.5%、防锈剂0.02~2%和助剂0.01~0.5%,余量为水。本发明钢轨焊缝超声波探伤耦合剂,通过将非离子表面活性剂作为助剂,其具有良好的亲水性和去污能力,可以使耦合剂在遇到雨水时更容易被水湿润和清洗,同时也能降低耦合剂与工件表面的附着力,便于挥发,实现防腐和抗氧化性能,同时改善耦合剂的性能,提高其润滑性、降低表面张力,有助于提高耦合剂在实际应用中的效果,使得耦合剂具有较高的可靠性。
