Abstract

The invention discloses a high-density polyethylene cable sheath material and a preparation method thereof. The high-density polyethylene cable sheath material comprises raw materials of high-density polyethylene, polysulfide rubber, modified glass fiber, nano attapulgite, ammonium polyphosphate, insoluble sulfur, an accelerator TMTD (tetramethyl thiuram disulfide), a cross-linking agent TAIC (triallyl isocyanurate), nano concrete slag powder, antioxidant 1010, sorbitan monopalmitate and trioctyl trimellitate. According to the high-density polyethylene cable sheath material and the preparation method, the high-density polyethylene is taken as a main material, and the high-density polyethylene cable sheath material has the characteristics of low smoke, no halogen, inflaming retarding, high mechanical strength and high insulation resistance; and the strength of the cable sheath material can be improved greatly through microwave and ultrasonic wave modification treatment of a reinforcing agent and glass fiber, and ammonium polyphosphate is taken as fire retardant, so that the flame retardant effect is obvious.

Description

technical field [0001] The invention relates to a high-density polyethylene cable sheath material and a preparation method thereof, belonging to the field of cable sheath material manufacturing.
