［Objective/Significance］Intumescent fireproof coatings play a vital role in the oil andgas industry by slowing down the heating rate of steel structures in fire scenarios through intumescentfoaming，thereby gaining time for personnel evacuation and fire-fighting，reducing fire-induced losses.［Analysis/Discussion/Progress］This paper introduced the requirements for fireproof coatings in theoil and gas field and the relevant standard systems，compared common types of fireproof coatings，and noted that solvent-free epoxy fireproof coatings have become the industry preference due to theirexcellent comprehensive properties. Furthermore，it provided an in-depth analysis of the latest research progress in solvent-free epoxy fireproof coatings，covering modification to resin systems，optimization of intumescent foaming flame-retardant systems，and the application of functional pigments and fillers.［Conclusion/Prospect］Solvent-free epoxy fireproof coatings are widely used in offshore oil platformsand onshore petrochemical facilities. Future development of fireproof coatings is expected to focus ongreen and environmental-friendly properties， long-term durability， adaptability to extreme environments，and high efficiency.
