The invention discloses a recovery utilization method of cable sheaths, and the method comprises the following steps: in the process of recovery utilization, conducting pulverization, cleaning and drying treatment on the impurities in the waste cable sheaths. The method can solve the problem of difficulty in removing impurities from the waste cable sheaths, and simultaneously can improve the utilization efficiency of the cable sheaths; the cleaned cable sheaths are used as a main raw material and matched with auxiliaries to prepare cable material particles; and the produced cable material has excellent mechanical properties and antibiotic and fire retardant properties, the properties of the cable material are more excellent than the properties of the original cable sheaths, and the cable material can be used for producing other cable products and applied to the fields of cable shields and the like. The recovery utilization method of cable sheaths has the advantages of extensive sources of materials, low cost and simple process requirements, recovers the waste cable sheath resources, simultaneously can create larger economic value, realizes regenerative utilization of the waste cable sheaths, and reduces environmental pollution.
