Description

technical field [0001] The invention belongs to the technical field of flame-retardant nanocomposite materials, and in particular relates to a flame-retardant nanocomposite material and a preparation method thereof. Background technique [0002] Nanocomposite materials are a new field that develops very rapidly in material science in recent years. In general, it refers to composite materials with at least one dimension of the dispersed phase smaller than 100 nm. The special function of nanocomposites mainly comes from the small size effect of particles and numerous interfacial recombination effects. As long as a small amount of nanoparticles is added to the polymer by melt mixing or in situ polymerization, it can greatly improve the polymerization. The mechanical properties, barrier properties and flame retardant properties of the material can be obtained, and much higher heat resistance, dimensional stability and electrical conductivity can be obtained than conventional fi...
