Novel flame-retardant sheath for display wire bundle

Abstract

The invention discloses a novel flame-retardant sheath for a display wire bundle. The novel flame-retardant sheath is prepared from the following raw materials in parts by weight: 65 to 75 parts of ethylene-propylene-diene monomer rubber, 25 to 35 parts of polyvinyl chloride, 6 to 13 parts of flame-retardant compound, 5 to 8 parts of fly ash, 12 to 17 parts of tailing with high content of magnesium and phosphor, 3 to 7 parts of red mud, 4 to 12 parts of carbon black, 3 to 6 parts of lithium porcelain stone, 2 to 4.5 parts of magnesium laurate, 1 to 5 parts of aramid pulp, 0.5 to 3 parts of active aluminum oxide, 1 to 2.5 parts of alpha-lipoic acid, and 0.5 to 1.5 parts of dioctyl azelate. The novel flame-retardant sheath has an excellent flame-retardant property.

Description

technical field [0001] The invention relates to a sheath, in particular to a novel flame-retardant sheath for a display wire harness. Background technique [0002] As the basic connecting part of the new display technology, the new display wire harness plays an important role, and its quality requirements are getting higher and higher, especially for safety and environmental protection issues. The wire harness mainly includes wires, insulating sheaths, wrapping materials and other components. In actual application, parts with suitable materials should be selected according to the working environment and performance requirements of the wire harness. Traditional wire harness insulation materials often have problems such as poor flame retardancy, high temperature deformation, and short service life, which bring a lot of inconvenience to actual use. It even threatens the safety of people's lives and properties. Therefore, it is urgent to change the original formula and improve t...
