Description
Technical field
The present invention relates to insulant field, particularly relate to soft type fire-retardant low smoke, zero halogen power line insulant and system thereof
Preparation 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.
Summary of the invention

On then carry out packing, temporarily depositing with vacuum aluminium plastic bag;
2) prepared by finished product:
2.1) silane coupler, crosslink agent DCP, antioxidant 300 are proportionally mixed, become silane after mixing and help
Agent, is sufficiently mixed rear silane adjuvant stand-by;
2.2) LLDPE-7042, LLDPE-8320, LDPE, EVA, catalysis masterbatch are drawn into blender in proportion and mix
Closing, suck drying tower, set 60 DEG C after mix homogeneously, drying time is more than half an hour, and material sucks raw material feed bin afterwards;
2.3) above material joins double screw extruder through weighing balance auto feed, by the silane adjuvant that prepared also
Joining twin screw through weighing balance in the secondth district, above material is grafted at twin screw;
2.4) material after twin screw is grafted is through Single screw extrusion, eccentric water smoke pelletizing, is transported to take off through transportation water pump
Water machine, through dehydration after be delivered to ebullated bed by conveying fan, by control material position height material is fully dried, after by
Suction feeder sucks finished product bin;
2.5) measure, pack and be finished product.
The method of the soft type fire-retardant low smoke, zero halogen power line insulant described in one-step method preparation, the method includes following
Step:
1) prepared by catalyst masterbatch: stirred in blender by the material of above catalyst masterbatch, first stirring at low speed 1 minute
High-speed stirred 3 minutes again, then release and pour extruder hopper into, extruder temperature: 140~180 DEG C, warp after twin-screw extrusion
Supercooling tank cools down, then carries out pelletizing after blower fan dries up, granule at drying tower, arrange 80 DEG C dry 2 hours with
On then carry out packing, temporarily depositing with vacuum aluminium plastic bag;
2) prepared by finished product:

Agent, is sufficiently mixed rear silane adjuvant stand-by;
2.2) carry out being heated to 90 DEG C by main equipment double conical rotary vessel;
2.3) LLDPE-7042, LLDPE-8320, LDPE, EVA, catalysis masterbatch are drawn in double conical rotary vessel, so in proportion
After lid is airtight, open double conical rotary vessel be dried, mix;
2.4) above dry materials, mixing 2.5 hours after, by liquid spraying device, standby silane adjuvant is joined
In material;
2.5) silane adjuvant is released after the absorption of 2.5 hours;
2.6) measure, pack and be finished product.
Due to the fact that and have employed above-mentioned technical scheme, the material of the present invention is mainly used in the insulating barrier of cable, to take
Being main for current PVC material, insulating properties are better than PVC, and PVC electric wire aging etc. on fire when can release poisonous and harmful
Gas, and silane Insulation Material is nontoxic.
Use the production of the present invention, screw speed and current stabilization, produce 240mm2, payingoff speed per minute 4.5
Rice;When extrusion, plastic emitting is uniform, and without granule, start occurs for 12 days without old glue continuously;Cable heat extend detection 70%~
80%, permanent deformation is in the range of 0~5%;Partial Discharge Detection is within 2PC, and industrial frequency withstand voltage tests 30 minutes without puncturing;Half
Finished product, finished product detection all meet GB/T 12706-2002 requirement.
