Abstract

The invention discloses an LSOH (Low Smoke Zero Halogen) flame-retardant cable material which comprises the following components by weight percent: 21%-29% of EVA (Ethylene-vinyl acetate copolymer) resin, 3%-9% of PE (Poly Ethylene) grafts, 60%-70% of an inorganic flame retardant, 1%-3% of metallic oxide, 0.2%-0.5% of vinyl trimethoxy silane, 1%-3% of a lubricant, 0.1%-0.3% of EBS (Ethylene Bis Stearamide) and 0.05%-0.5% of an antioxidant. The LSOH flame-retardant cable material which is obtained by adopting the components and the ratio thereof has a good effect of low smoke flame retardancy, meets the requirement of vertical burning tests, can be used for replacing the traditional PVC (polyvinyl chloride) cable materials, and is secure.

Description

technical field [0001] The invention relates to the field of electrical materials, in particular to a low-smoke, halogen-free, flame-retardant cable material. Background technique [0002] In recent years, it has been found that more than 80% of the causes of death in fire accidents are related to the dense smoke and toxic gases produced by materials. With the rapid development of my country's modern industry, safety and prevention measures should be more and more perfect. In many large public places, in order to avoid the secondary disaster caused by cable fire (a large amount of smoke and acid gas are produced when the cable burns), special The wires and cables used to transmit electric energy and communication signals are not only required to have flame retardant properties such as preventing flame spread when the cable and the surrounding environment catch fire, and can maintain the cable to continue to transmit electric energy and communication signals. Low smoke generat...
