Abstract

The present invention of halogen-free, expansive, flame-retardant, cable material and its environmental-protection-type cable belong to cable field. The halogen-free, expansive, flame-retardant, cablematerial includes insulated material and sheathing compound; the weight units formula of the insulated material includes: organic montmorillonite with 3-5 units, polyolefin resin with 55-65 units, nitrogen-phosphorus, halogen-free, expansive flame-retardant material with 30-40 units, antioxidant with 0.01-0.02 units, modifier with 5-10 units; adding 1-2 units of natural mouse-ant-dispelling-agentmicrocapsule into the prepared cable material, can prepare the halogen-free, expansive, flame-retardant, mouse-ant-defending, cable sheathing compound. The cable's insulated layer can select generalcrosslinking polyethylene or the halogen-free, expansive, flame-retardant, insulated, cable material in the present invention; the cable's sheathing layer selects the halogen-free, expansive, flame-retardant, mouse-ant-defending, cable sheathing compound in the present invention. The product of the present invention has the following characters: every electric property of the cable all meets the indexes of national standards; the flame retardancy meets the order of GB / T 19666 combustion test; the amount of smoke is little, while burning the cable, and the transmittance can reach 60-94%; the cable can defend mouse and ant.

Description

technical field [0001] The invention relates to a halogen-free intumescent flame-retardant cable material and an environment-friendly cable prepared therefrom, belonging to the field of electric cables, in particular to a halogen-free intumescent flame-retardant cable material, a production method thereof, and an environment-friendly rodent-proof and ant-proof cable. Background technique [0002] At present, my country is implementing urban and rural power grid transformation, western development and large-scale upgrading and transformation of communication facilities, and there is a large demand for wire and cable products. As people pay more and more attention to the biological safety protection system, new requirements are put forward for the functions of wire and cable products, that is, to meet the requirements of safety, environmental protection, and pest control, but the existing cables cannot meet the above performance requirements. Prior to this, the traditional org...
