Problems solved by technology

In the past, anti-rodent agents were added to the plastic materials of cable sheaths, such as cycloheximide, terpenoid monomers, etc., and most of them were "poisonous". The "lose-lose" result of being poisoned does not meet the environmental protection requirements

Abstract

The invention relates to a 90-DEG C rat-proof and termite-proof PVC sheath material and a preparation method thereof. The 90-DEG C rat-proof and termite-proof PVC sheath material is prepared from type III PVC resin powder, dinonyl terephthalate, epoxidized soybean oil, polyethylene wax, trioctyl trimellitate and a rat-proof and termite-proof agent A. The rat-proof and termite-proof PVC sheath material has an excellent rat-proof and termite-proof effect, and the protection rate reaches 93% or above. Meanwhile, the 90-DEG C rat-proof and termite-proof PVC sheath material is good in tensile strength and compressive strength, good in mechanical property and long in service life, a cable sheath is not prone to being broken, crushed and squeezed in the using process, and a cable core is effectively protected.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a 90°C anti-rat and ant-proof PVC sheath material and a preparation method thereof. Background technique [0002] Wires and cables are used to transmit electric (magnetic) energy, information and wire products that realize electromagnetic energy conversion. In a broad sense, wires and cables are also referred to as cables for short. In a narrow sense, cables refer to insulated cables. In modern society, wires and cables can be seen everywhere, such as wires and broadband access lines used in homes and hotels; power cables and overhead cables laid by power departments. Wire and cable occupies a very important position in the national economy and social activities, and with the rapid development of the economy, the wire and cable industry has become the second largest industry in my country. Among them, the 90°C sheathing material means that when it is prepared into a cable, the ma...
