Description
Technical field
The present invention relates to insulant field, particularly relate to a kind of Zero halogen flame resistance polyethylene sheath insulation material and preparation thereof
Method.
Background technology
Cable industry uses polyolefinic kind mainly to have PE, PP, EVA and EEA etc., and wherein relative quantity is big, applicating history
Long is mainly PE, and it has HDPE, MDPE, LDPE, LLDPE and the XLPE through crosslinking, and their application does not the most need to speak more.OK
In industry, the most polyolefinic application and development trend are concentrated mainly on following several respects:
(1) seriation of low smoke, zero halogen material, improvement
Halide-free low-smoke fireproof cable material is development in recent years kind faster, meets the thermoplastic of IEC92-359 standard-required
Moulding mixture is the most increasingly widely applied.Use along with oil platform, nuclear power station, cable for ship and other bad environments
The requirement of occasion, the range of application of cross-linking type low smoke, zero halogen CABLE MATERIALS will be increasing.
(2) resistance to electricity trace material
Resistance to electricity trace CABLE MATERIALS is as the popularization and application of ADSS (All Dielectric Self-Supporting Aerial Optical Fiber Cable), and gradually causes everybody
Attention.In fact, have the trace requirement of resistance to electricity at 10kV and above aerial cable for producing corona under preventing at damp condition, by
In its insulant (XLPE, HDPE), itself there is certain resistance to electricity trace, substantially can guarantee that the requirement of aerial cable resistance to electricity trace,
So problem does not highlight.And ADSS mainly sets up along the high-tension line of 110KV, 220KV, the electric erosion resistance of its sheath will
Directly affect cable lifetime, therefore the resistance to electricity trace of sheath material is had more harsh requirement, i.e. apply actually used pulling force
90% tension force in the case of, carry out 1000 hours resistance to electricity trace test, it needs this custom-designed formula system promising, wherein
Key be resistance to electricity the use of trace agent, superior physical and mechanical properties, the balance of good process processability.At present, English, moral,
The life search of ADSS is also being continued by Mei Deng state, and the most how its emphasis improves is placed in cable sheath material in space electric field
Electrical erosion resistance.
(3) crosslinked with silicane material
Organosilane crosslinked polyethylene insulation material commonly uses in 3KV and following power cable.Along with crosslinked with silicane technology
Universal, other has product to come out such as crosslinked with silicane strippable shielding material, LSOH anti-flaming material, second the third CABLE MATERIALS the most in succession.State
On inherent crosslinked with silicane strippable shielding material, existing producer works, and silane crosslinked halogen-free flame-retardant material, second the third CABLE MATERIALS are still
Few understand for everybody, certainly let alone apply.
(4) cross-linking radiation polyolefin material
Cross-linking radiation material and technology have obtained the application of maturation on power cable, aerial cable and equipment line.Many institutes
Known, 105 DEG C and temperature below grade in industry, requirement all can be met with XLPE, XLPVC or PVC, more than 150 DEG C, silicon
The application of the kinds such as rubber, fluoroplastics, polyimides is the most ripe, but answering in medium temperature grade (such as 125 DEG C, 150 DEG C)
With in exploitation, bigger with external gap.
