Description
Technical field
The present invention relates to a kind of halogen-free cable, and in particular to improves low-smoke halogen-free inflaming-retarding cable.
Background technology
In recent years, it has been found that dense smoke that personnel's cause of death more than 80% in fire incident is produced with material and poisonous
Gas is relevant.With developing rapidly for China's modern industry, Safety countermeasure also should be more and more perfect, many large-scale public
Place, for the secondary disaster (substantial amounts of smog and sour gas are produced during cable fire) for avoiding ignition of cable from causing, to specializing in
Transmission electric energy and the electric wire that uses of communication signal, are not required nothing more than with when cable and surrounding environment catch fire, with can hinder
The only fire resistance such as propagation of flame, and cable can be maintained to continue to transmit electric energy and communication signal, and should also have in burning
Low-smoke, produce gas attack it is low, beneficial to worker safety withdraw scene performance, i.e., should make cable have Halogen,
The performance such as low cigarette, fire-retardant.
Cable insulation refers to the clad that one layer is played insulating effect outside cable core in the construction of cable, the insulation of current cable
Layer is mainly made up of polymer.Low-smoke halogen-free combustion-preventing cable insulation layer is general to use polyolefin as base-material, because polyolefin is pure
Hydrocarbon, resolves into water and carbon dioxide during burning, obvious smog and pernicious gas are not produced.It is simultaneously full in order to reach
Sufficient Halogen, low cigarette, fire-retardant target, current topmost method are a large amount of addition aluminium hydroxides or hydrogen-oxygen in cable insulation
Change the inorganic combustion inhibitors such as magnesium, its loading generally requires the amount more than base-material, and this is greatly lowered the mechanical-physical of material
Can, the performance indications such as its tensile strength, elongation at break is declined to a great extent, the ability for then bearing mechanical external force declines.Largely
The filling of inorganic matter, can also cause the resistance to tearing of CABLE MATERIALS to be deteriorated, once cable locally produces small gap after small gap, stress
Can progressively it expand, and stress is bigger, and the speed that breach expands is faster, ultimately results in cable insulation sleeve and integrally ruptures.
The content of the invention
The technical problems to be solved by the invention are to add a large amount of inorganic metals in the insulating barrier of existing halogen-free flame-retardant cable
Fire retardant, greatly reduces the tensile strength and resistance to tearing energy of cable, causes the quality reduction that cable is overall, it is therefore intended that carry
For improving low-smoke halogen-free inflaming-retarding cable, by preparing the improvement of formula, the addition of inorganic metal fire retardant is reduced, is being ensured
While cable low-smoke non-halogen flame-retardant performance, the tensile strength and resistance to tearing energy of cable are improved.
