Abstract
A kind of halogen-free flame-retardant polyolefin electric wire and cable material, the raw material including following weight percent: polyethylene 40-80%, ethylene-vinyl acetate copolymer 5-20%, composite nanometer flame retardant 15-40%, auxiliary agent 5-20%, crosslinking agent 0.1-0.5%.The present invention with it is conventional by expansibility flame-proof agent compared with the cable material that inorganic hydroxide is simply mixed, cable material of the present invention has better material uniformity, and material internal does not have common micropore, has better flame-resistant insulation performance.
Description
Technical field
The present invention relates to a kind of flame retardant cable, especially a kind of fire-retardant electricity comprising halide-free low-smoke fireproof cable jacket material
Cable.
Background technique
With quick, the steady-state growth of national economy, the rapid development of urban construction is large quantities of to have built building for various functions
Object is built, the probability that fire thus occurs accordingly increases.It, should be using height in the occasion of the relatively intensive easy generation fire of population
Fire-retardant fireproof type power cable is to meet requirement.Since common high flame retardant fireproof power cable insulate only with inorganic
The overlapping of composite insulating material mica tape is wrapped, and the mica powder above mica tape, which is easy to fall off, to be caused under insulation performance and fire protecting performance
Drop, using the gap for squeezing out filled-type silicon rubber filling cable core, this process needs dedicated silicon rubber extrusion equipment could be into
Row, metal layer use longitudinal wrap argon arc welding copper strips, higher cost.
The elements such as the main carbon containing, hydrogen of polymer, are easy ignition under the action of oxygen and heat.When polymer material is heated
Afterwards, heat conduction enters material internal, and material absorbs heat melting first；As temperature increases, polymer starts the fracture for key occur,
Occur to thermally decompose and release containing hydrocarbon imflammable gas；Enough fuel gas act on oxygen sending out at a certain temperature
Raw burning；The heat that gas-phase combustion generates passes undecomposed solid back again, further speeds up the decomposition of polymer, and generation more may be used
Combustion property gas, keeps burning more violent.It can be seen that combustible, heat and oxygen be maintain burning three fundamentals, three
Person is indispensable.Therefore, when carrying out flame-retardant modified to polymer, cutting maintains one of the three elements of burning, can reach
Fire-retardant purpose.
Polymer it is flame-retardant modified with study its combustion process and characteristic it is closely bound up.In essence, fire-retardant is exactly logical
Prevent or weaken in burning three elements one or several are crossed to realize.Fire retardant mechanism is actually fire retardant to burning three
Element specifically prevents or weakens effect.Fire retardant mechanism can specifically be divided into multiple types, such as form non-combustible protective film, produce
Raw high density gas separation layer, capture free radical terminate chain reaction, the thermal stability for improving polymer etc..In summary, for
Polymer it is flame-retardant modified it is fire-retardant with condensed phase, gas phase is fire-retardant, synergistic is fire-retardant and interrupts based on four kinds of mechanism such as heat exchange.
Metal hydroxide combustion inhibitor decomposition temperature is not high, volatile, at low cost, in addition to flame retardant effect, also has
Property that is nontoxic, inhibiting smoke, is known as nuisanceless fire retardant.But there are loadings greatly and gathers for metal hydroxide combustion inhibitor
Close object poor compatibility and to the processing of polymer, Effect on Mechanical Properties is larger the disadvantages of, these are metal hydroxide combustion inhibitors
It must be solved the problems, such as in research and development and application.
Expansion type flame retardant is mainly combined by the substance containing elements such as nitrogen, phosphorus, carbon, is had between each element fire-retardant
Synergistic effect.When burning, expansion type flame retardant can generate foam carbon-coating in frosting, to play heat-insulated, suppression cigarette, anti-
Molten drop and other effects is realized fire-retardant.Though more to the report of expansion type flame retardant at present, it studies the stage for still falling within ground zero,
Practical application is less.In addition, expansion type flame retardant has excellent fire-retardant potential quality really, but it is poor, easy with polymer compatibility
The disadvantages of moisture absorption, restricts its industrialized process to a certain extent.Future will be from water-fast, phase to the research of expansion type flame retardant
Capacitive and expansion molecular scale etc. set about improving.
