Abstract Magnetorheological materials (MRs) are fast-response intelligent materials that have been widely used in many fields. In this study, modified carbonyl iron powder was used as the filler, and an epoxy resin/acrylate interpenetrating polymer network (IPN) MR with oil-surface bonding was prepared. Infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and scanning electron microscopy were employed to explore the reaction process and the microstructure of the material. The ingredient proportion was optimized via a single-factor experiment. The magnetic and mechanical properties of the material were also tested, and the optimum amount of filler was determined from the test results. The synthesized IPN-MR exhibited the characteristics of oil-surface bonding, magnetic field response, rapid curing and high strength. It has broad application prospects for rapid damage repair of oil pipeline. A simulation experiment was performed to test the repair effect.

Highlights A new repair method for long-distance oil pipelines is proposed. An interpenetrating polymer network magnetorheological material was synthesized. The synthesized material has oil-surface bonding and magnetic response characteristics. The structure and reaction of the magnetorheological material were analyzed. A simplified model was designed to replace full-size pipes for experiments.
