Description
Technical field
The present invention relates to field of cables, specifically, the present invention relates to a kind of halogen-free anti-flaming polyolefin power cable.
Background technology
Along with industrial expansion, electric wire demand increases day by day, and mostly belongs to organic polymer for the insulating sheath material of electric wire, and this kind of electric wire easily causes burning under the conditions such as high pressure, thermal source, certain temperature, oxygen concentration.So the fire-retardant of cable material of polyolefin seems very necessary, halogen containing flame-retardant flame retarding efficiency is high, but when fire occurs, Halogen fire retardant material can discharge a large amount of toxic gas, causes " secondary harm " the mankind, environment.Therefore, along with people are to the requirement of environmental protection, development of new, phosphorus flame retardant etc. are the focuses of cable material research field.
At present, EVA/MH is the study hotspot of non-halogen flame-retardant cable, but due to the shortcoming of flame retardant of magnesium hydroxide self, how while reduction flame retardant of magnesium hydroxide consumption again can guarantee system to possess good flame retardant resistance be study hotspot always.
Summary of the invention

More preferably, described fire retardant is magnesium hydroxide.
More preferably, described silane coupling agent is KH550.
More preferably, described compatilizer is POE-g-MAH.
More preferably, described flame retardant is 7-n-pentyloxy-4,5-dihydro-2H-[1,2,4]-triazole [4,3-a] and quinoline-1-ketone.
The present invention 7-n-pentyloxy-4,5-dihydro-2H-[1,2,4]-triazole [4,3-a] is also provided and quinoline-1-ketone for the purposes in flame retardant.
Halogen-free anti-flaming polyolefin power cable of the present invention has good flame retardant resistance, is extremely suitable for being used in the field such as factories and miness, engineering.
