High flame retardance heat resistant low smoke no-halogen cable sheath and its production process

Abstract

The high flame retardance heat resistant low smoke no-halogen cable sheath material features its main materials including SEBS, white oil, PP, PS, maleic anhydride grafted SEBS, P-N fire retardant, coupler, tackified coumarone resin, superfine white carbon black, siloxane, antioxidant 1010 and PS802, and environment friendly color powder. The cable sheath material as one kind of green product contains no halogen, no heavy metal and other environment harming matter, and has high fire retarding performance, high strength, high extensibility and high heat resistance.

Description

technical field [0001] The invention relates to a novel environment-friendly low-smoke and halogen-free cable material, which discloses a formula and a processing technology of a low-smoke, halogen-free and flame-retardant cable material with a high temperature resistance level. Background technique: [0002] In response to the international environmental protection trend, PVC will be restricted or banned in many wire application fields, because it will produce harmful gases and more smoke when burned. In the event of an accident such as a fire, these harmful gases and smoke will pose a threat to human health. Therefore, in many places such as home appliance power cables, network cables, computer peripheral cables, etc., low-smoke halogen-free wires will replace traditional PVC wires. [0003] In the past, we used one or two composites of thermoplastic materials such as EVA or PE and PP to make low-smoke and halogen-free materials. The wires made would appear hard, without ...

Problems solved by technology

[0003] In the past, we used one or two composites of thermoplastic materials such as EVA or PE and PP to make low-smoke and halogen-free materials, and the wires made would appear hard, without elasticity and flexibility, and without a soft feel.
