The　inherent　difficulty　in　preservation　and　processing　of　conventional　red　phosphorus　flame　retardant　severely　limits　its　growing　applications　in　polymer　materials,　thus,　there　is　an　urgent　need　to　exploit　effective　technology　to　modify　red　phosphorus.　Functionalized　lignin-based　compounds　can　provide　a　great　potential　in　improving　the　preservation　and　processing　of　red　phosphorus.　Here,　we　prepared　melamine　modified　lignin/aluminum　phosphate　coated　red　phosphorus　(LMAP@RP)　and　used　it　as　the　flame　retardant　of　acrylonitrile-butadiene-styrene　(ABS)　resin.　With　25wt%　loading　LMAP@RP,　the　ABS　samples　show　excellent　flame　inhibiting　capacity　and　reached　UL-94　V-0　rating.　Cone　calorimetry　test　results　show　that　the　peak　heat　release　rate,　total　heat　release　and　total　smoke　release　of　ABS/25LMAP@RP　are　reduced　strikingly　by　64.6%,　49.3%,　and　30.1%,　respectively.　The　char　residue　is　15.36wt%　and　the　char　layer　is　continuous　and　dense.　The　outstanding　flame　retardant　and　smoke-suppressant　performances　of　LMAP@RP　show　its　application　prospect　for　ABS.　©　2022,　Wuhan　University　of　Technology　and　Springer-Verlag　GmbH　Germany,　Part　of　Springer　Nature.
