Description
Technical field
The present invention relates to the cable material in a kind of wire cable material field, particularly to a kind of resistance to impact flame-retardant cable material.
Background technology
With global economy fast development, people constantly strengthen to the understanding of electric wire aging initiation fire accident, right
The environment friendly of electric wire requires also more and more higher.Halogen burning produce poison gas to the harm of human body and environment be
Well-known.So, how to reduce the occurrence index being caused by electric wire and death rate during fire occurs？Low cigarette,
Halogen, fire-retardant, environmental protection, the developing direction becoming wires and cables industry such as high temperature resistant.Halogen-free flame-retardant wire cable, can be good at
Solve the problems, such as the contaminative to environment and injury is produced to the person, but be to meet Flame Retardancy and physical and mechanical properties
Balance, adds antimony oxide sometimes in halogen-free flame-retardant system, and antimony oxide, during production and processing and use, connects
After tactile human body skin, human body can be produced with certain harm (pruitus, redness), more seriously causing death, at present
Some terminal clients clearly prohibit the use of to the electric wire containing antimony oxide.
