The invention discloses an anti-termite environment-friendly cable material and a preparation method thereof. This cable material is composed of components according to following parts by weight: 80-120 parts of high-density polyethylene, 10-20 parts of low-density polyethylene, 15-35 parts of menthol, 1-3 parts of a preservative, 2-4 parts of an antibacterial agent, 2-7 parts of epoxidized soybean oil, 1-2 parts of zinc stearate, 15-25 parts of a flame retardant, 5-15 parts of talcum powder, 15-20 parts of light weight calcium carbonate, and 3-5 parts of a silane coupling agent. The invention overcomes the defect that a conventional anti-termite cable is toxic, the menthol is added to this formulation, menthol cool dissipated by the menthol destructs a warm environment around the cable, and stimulating odor of the menthol can dispel termites, giving a great reduction in cable attack and destruction by the termites.
