The invention discloses a preparation process of an environment-friendly flame-retardant sheathing material for a new energy automobile charging pile, comprising the following steps of: mixing silane-coated modified aluminum hydroxide, diethyl aluminum phosphinate, calcined kaolin, polyethylene wax and an antioxidant in a high-speed mixer to obtain a mixed mixture; mixing a mixture obtained by mixing a polyolefin elastomer, polypropylene resin, a styrene-butadiene copolymer and polyethylene glycol distearate in a high-speed mixer for 8-15 minutes to obtain mixed raw materials; 3, kneading by adopting a kneading machine, and mixing the mixed raw materials obtained in the step 2 in the kneading machine at 110-150 DEG C for 15-30 minutes to obtain mixed raw materials; putting the mixture intoa single-screw reciprocating machine for mixing, and then extruding and granulating through a single-screw extruder. Under the condition of IRM902 test oil 168h/100 +/-2 DEG C, the retention rate oftensile strength of the ob
