Abstract With the advantages of lightweight and low thermal conductivity properties, polymeric foams are widely employed as insulation materials for energy‐saving buildings but suffer from inherent flammability. Flame‐retardant coatings hold great promise improving fire safety these without deteriorating mechanical‐physical properties foam. In this work, four kinds sulfur‐based flame‐retardant copolymers synthesized via a facile radical copolymerization. The sulfur‐containing monomers serve agents including vinyl sulfonic acid sodium (SPS), ethylene (VS), p‐styrene sulfonate (VSS). Additionally, 2‐hydroxyethyl acrylate (HEA) 4‐hydroxybutyl to enable strong interface adhesion with through interfacial H‐bonding. By using as‐synthesized waterborne coating thickness 600 µm, coated polyurethane foam (PUF) can achieve desired V‐0 rating during vertical burning test high limiting oxygen index (LOI) >31.5 vol%. comparing fire‐retardant coatings, poly(VS‐ co ‐HEA) PUF demonstrates best capability performance, lowest peak heat release rate 166 kW m −2 highest LOI 36.4 This work provides new avenues design performance optimization advanced coatings.
