Description
Technical field
The present invention relates to low cigarette flame resistant cable material field, particularly relate to a kind of low smoke and zero halogen ceramic flame-resistant cable and preparation method thereof.
Background technology
Along with the sharp increase of urban population, along with the continuous increase of Highrise buildings, subway, airport, station, large hotel, supermarket, hospital and large-scale Public Physical Education, public place of entertainment, public transit facility, the importance of fire-fighting, fire safety problem highlights.At present when, Highrise buildings large-scale at some or public place presence of fire, fire can cause circuit malfunctions, alarm, automatically-controlled door, elevator, sprinkling system, various signal delivery system and other emergency rescue equipment are quit work, causes field staff to be difficult to escape.If combustiblematerials releases a large amount of smog, particularly toxic gas simultaneously, the generation of secondary disaster, serious threat also will be caused the safety of life and property of people.
The flame resistant cable of the fireproof electric wire and cable adopted at present both at home and abroad mainly magnesium oxide mineral insulation flame resistant cable and Mica tape.The former needs special manufacturing and processing equipment, and these equipment mostly need import, expensive, and fund input is too large, and the outer jacket of this cable is full copper, and not only cost is high, and laying installation difficulty is large, is difficult to universal on a large scale use and popularization etc.And the latter needs multiple wraps in process of production, complex process, and due to the restriction of processing condition, often easily cause seam lap place to occur defect, mica tape embrittlement after burning, easily comes off, also cause fire-resistant weak effect, thus be difficult to ensure communication, electric power in case of fire safe and smooth.In view of the deficiency that these two kinds of flame resistant cables exist in the links such as production and use; being developed can porcelain polymer (ceramifiablepolymer) flame resistant cable material; this material is a kind of more excellent fire-retardant material; its advantage has the character identical with common wiring cable insulation when room temperature; meet after high temperature catches fire and be transformed into hard ceramic protective layer through porcelain; the ablation of thousands of degree naked light can be resisted, and there is certain physical strength.Although the thirties in 20th century can be traced back to the research of this respect, slower development always both at home and abroad, until in recent years to can the research of ceramic flame resistant cable just increase to some extent, ceramic flame resistant cable just becomes one of the study hotspot in flame resistant cable field.
