The present invention discloses an insulating rod body material and its preparation method, falling within the field of insulating rod technology. It comprises the following raw materials by weight: polycyclopentadiene 100 parts, flame retardant 7-10 parts, inorganic nano-filler 5-8 parts, coupling agent 2-3 parts, lubricant 2-3 parts, and light stabilizer 0.7-1 part. The raw materials are added to a high-speed mixer in the specified proportions. The mixture is then fed into a twin-screw extruder for melt extrusion and pelletization, yielding the insulating rod body material. The insulating rod material of the present invention uses polycyclopentadiene as the matrix and incorporates a synthetic flame retardant to enhance flame retardancy. The synthetic flame retardant contains multiple effective flame-retardant components, creating a synergistic flame-retardant effect. Furthermore, the flame retardant forms chemical bonds with the matrix, thereby addressing the migration and leaching issues associated with conventional organic flame retardants and improving the long-term stability of the flame-retardant effect. Ultimately yielding an insulating rod material that combines mechanical properties, heat resistance, and flame retardancy.
