Abstract

The invention discloses a low-smoke environment-friendly cable material and a preparation method thereof. The low-smoke environment-friendly cable material is mainly prepared by composited materials including ethylene-vinylacetate co-polymer EVA, high-density polythylene HDPE, fire retardant, zinc borate, roasting zeolite powder, nano calcium carbonate powder, silane coupling agent, titanic acid esters, oxidation inhibitor, lubricant and cross-linking agent, which are all mixed according to a specific proportion of parts by weight. The preparation method is simple, convenient in operation andreasonable in formula of the composited materials, and the prepared cable material is high in mechanical performance and fire retardant property and resistant to high temperature, and is low in smokeand non-toxic when being burned.

Description

technical field [0001] The invention relates to a low-smoke environment-friendly cable material and a preparation method thereof, belonging to the field of cables. Background technique [0002] With the rapid development of the economy, wires and cables are widely used in various industries and fields. With the frequent occurrence of electrical fire accidents, the flame retardant problem of wires and cables has gradually attracted the attention of countries all over the world. When the cable burns, it releases a large amount of smoke and toxic and corrosive gas, which is a risk factor in a fire. It hinders people's safe evacuation and fire fighting work during a fire, causing serious loss of life and property. At the same time, with the development of the communication industry, the automobile industry and the computer industry, especially in many occasions such as aviation wires, automobile wires, high-temperature instrument cables, and oil drilling platform cables, it is ...
