Description

Fireproofing cable material without halide
Technical field
The present invention relates to a kind of fireproofing cable material without halide, belong to Material Field.
Background technology
Due to polyolefine have that relative density is little, chemical proofing and water-tolerant, good physical strength and electrical insulating property, have elasticity and can keep the features such as good thermoplasticity simultaneously, therefore polyolefin compositions has been widely used in various field.When polyolefine is used for electric wire, need to add fire retardant wherein, fire retardant great majority at present for polyolefins are halogen flame system, good flame retardation effect, cost performance are high, but it is large to environmental hazard, its fire retardant mechanism determines can be fuming in fire-retardant process, produces corrosive gases, causes serious injury environment and human body.
Low-smoke halogen-free inflaming-retarding cable is the same with common cable under non-fire condition, therefore certain mechanical and physical performance and electric property must be possessed, to meet the service requirements of cable, take polyolefine as base-material due to halogen-free low-smoke flame retardant material, improve its flame retardant properties by adding fire retardant, a large amount of interpolations of fire retardant can cause the mechanical and physical performance of material and the deterioration of electric property and processing characteristics.In addition, these materials are under long term heat ageing and environmental activity, intermolecular chemical bond can rupture, produce living radical or active ion, cause the DeR of macromolecular chain, oxidizing reaction, isomerization reaction, final result is that the molecular weight of polymer materials is more and more little, even loses the character of polymkeric substance, the properties of cable insulation material is all significantly declined, and the mechanical property of existing low-smoke halogen-free inflaming-retarding cable and electricity function index are a little less than common material.
