Abstract: The present disclosure relates to a flame retardant composed of multi-component phase change material particles. These particles consist of paraffin wax, nano-flame retardant, and conventional flame retardant. The phase change material is modified with nano-flame retardant and physically coated with conventional flame retardant. The multi-component phase change material flame retardant is formed by creating a two-layer nucleus-shell structure. The nucleus core is made up of the conventional flame retardant, while the shell layer is composed of the nano-flame retardant doped phase change material. The multi-component flame retardant material combines the performance advantages of phase change material, nano flame retardant, and conventional flame retardant. The combination of nano flame retardant and phase change material weakens the disadvantages of phase change material and allows for the full utilization of the energy storage capabilities of the phase change material.
