Abstract
The disclosure discloses a phosphorus-nitrogen-zinc two-dimensional supramolecular coated molybdenum disulfide hybrid flame retardant and application thereof, and belongs to the technical field of halogen-free flame retardant. Components of the phosphorus-nitrogen-zinc two-dimensional supramolecular coated molybdenum disulfide hybrid material in the disclosure include, by weight, 1-2 parts of molybdenum disulfide, 1-1.5 parts of zinc salt, 5-8 parts of a nitrogen-containing compound and 5-10 parts of a phosphorus-containing compound. As a flame retardant, the hybrid material of the disclosure effectively exerts an organic-inorganic synergistic flame retardant effect; the flame retardant efficiency of molybdenum disulfide is improved; the addition amount of the flame retardant in a matrix is reduced; the mechanical properties of the matrix can be improved at the same time; and the material has a very good application prospect.
