In prior art, cotton covered wire typically uses polrvinyl chloride as insulation.This cotton covered wire is special due to its structure
Point and insulant fire resistance limit, and bunchy fire resistance can only pass through GB/T18380B class, it is impossible to passes through
GB31247B1Level.When fire occurs, the cotton covered wire that bunchy lays once burns, and prolongs combustion distance, burning
Produce amount of heat and cigarette, fire hazard can be aggravated, it is difficult to strive for the longer time for escape and rescue.And
Low-smoke halogen-free polyolefin insulating cotton covered wire, owing to using low-smoke halogen-free polyolefin as insulation, solves when catching fire
The problem that smoke-producing amount is the biggest, but flame retardant effect still can only pass through GB/T18380B class, it is impossible to pass through
GB31247B1Level.Low-smoke halogen-free polyolefin material with the addition of a large amount of magnesium hydroxide, aluminium hydroxide flame-retardant simultaneously
Agent, macromolecular chain binding strength is deteriorated, and between macromolecular chain, gap becomes big, and the mechanical performance of material is substantially reduced (draws
Stretch intensity and only have 10MPa), water penetration is greatly increased, about ratio PVC electric wire insulation resistance after electric wire immersion
Reduce by two orders of magnitude.And existing electric wire heat dispersion is poor, it is not easy to solid when many electric wires are put together
Fixed.
Summary of the invention
The technical problem existed based on background technology, the present invention proposes a kind of embedded glass braiding fire retardant
Electric wire processing technique.
