The invention discloses a flame-retardant recycled plastic particle, which comprises a particle body, through holes, a recyclable part and an inner layer, wherein the through holes are embedded and connected to the surface of the particle body; the recyclable part is fixedly connected to the inner side in the particle body; the inner layer is fixedly connected to a middle position in the particlebody; a vent pipe is penetrated and connected in the middle position of the recycled part; and the outer side in the inner layer is fixedly connected with an inner layer transmission pipe. The inner layer can improve the flame-retardant effect of the particle, an intumescent flame retardant in a plastic wire generates white bubbles when the particle body is at a high temperature, and therefore, the volume of the intumescent flame retardant is expanded to enable the intumescent flame retardant to reach an empty cavity; and then, the intumescent flame retardant is transmitted through a check value and is transmitted int
