Description
Technical field
The present invention relates to insulant field, particularly relate to black aerial insulated cable and preparation method thereof.
Background technology
Cable industry uses polyolefinic kind mainly to have PE, PP, EVA and EEA etc., and wherein relative quantity is big, applicating history is long
Mainly PE, it has HDPE, MDPE, LDPE, LLDPE and the XLPE through crosslinking, and their application does not the most need to speak more.
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, has met the thermoplastic moulding mixture of IEC92-359 standard-required
Increasingly it is widely applied.Use occasion along with oil platform, nuclear power station, cable for ship and other bad environments
Requirement, 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 note
Meaning.In fact, the trace requirement of resistance to electricity is had for producing corona under preventing at damp condition, due to it at 10kV and above aerial cable
Insulant (XLPE, HDPE) itself has certain resistance to electricity trace, substantially can guarantee that the requirement of aerial cable resistance to electricity trace, therefore
And 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
In the case of 90% tension force, carrying out the resistance to electricity trace test of 1000 hours, it needs this custom-designed formula system promising, therein
Key is resistance to the electricity 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 the anti-of cable sheath material in space electric field
Galvanic corrosion.
(3) crosslinked with silicane material
Organosilane crosslinked polyethylene insulation material commonly uses in 3KV and following power cable.Along with popularizing of crosslinked with silicane technology,
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.Domestic at silicon
On alkane crosslinking strippable shielding material, existing producer works, and silane crosslinked halogen-free flame-retardant material, second the third CABLE MATERIALS are still few for everybody
Understand, 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.It is known that
105 DEG C and temperature below grade in industry, all can meet requirement with XLPE, XLPVC or PVC, more than 150 DEG C, silicon rubber
The application of the kinds such as glue, 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
In order to solve above-mentioned technical problem, it is an object of the invention to provide black aerial insulated cable.
In order to realize above-mentioned purpose, present invention employs following technical scheme:
Black aerial insulated cable insulant, this insulated cable includes insulant and is arranged on the wire within insulant,
Insulant is prepared by following component by weight percentage:
As preferably, insulant is prepared by following component by weight percentage:
Two step method prepares the method for above-mentioned black aerial insulated cable insulant, and the method comprises the following steps:
1) prepared by catalyst masterbatch: catalyst masterbatch is LDPE, organotin, antioxidant 1010, anti-oxidant DLTP, fluorubber
Masterbatch, black master batch；
Above material is stirred in blender, first stirring at low speed 1 minute high-speed stirred 3 minutes again, then release and pour extrusion into
Machine hopper, extruder temperature: 140～180 DEG C, cool down through supercooling tank after twin-screw extrusion, then dry up through blower fan
After carry out pelletizing, granule, at drying tower, arranges 80 DEG C of drying and then carries out packing, temporarily depositing with vacuum aluminium plastic bag for more than 2 hours
Put；
2) prepared by finished product:
2.1) silane coupler, crosslink agent DCP, antioxidant 300 are proportionally mixed, after mixing, become silane adjuvant,
It is sufficiently mixed rear silane adjuvant stand-by；
2.2) LLDPE-7042, LLDPE-8320, catalysis masterbatch are drawn into blender in proportion and mix, and inhale after mix homogeneously
Entering drying tower, set 60 DEG C, 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, and the silane adjuvant prepared is also passed through meter
Amount claims to join twin screw in the secondth district, and 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 dewaterer through transportation water pump,
Through dehydration after be delivered to ebullated bed by conveying fan, by control material position height material is fully dried, after inhaled by vacuum
Material machine sucks finished product bin；
2.5) measure, pack and be finished product.
One-step method prepares the method for above-mentioned black aerial insulated cable Insulation Material, and the method comprises the following steps:
1) prepared by catalyst masterbatch: catalyst masterbatch is LDPE, organotin, antioxidant 1010, anti-oxidant DLTP, fluorubber
Masterbatch, black master batch；
Above material is stirred in blender, first stirring at low speed 1 minute high-speed stirred 3 minutes again, then release and pour extrusion into
Machine hopper, extruder temperature: 140～180 DEG C, cool down through supercooling tank after twin-screw extrusion, then dry up through blower fan
After carry out pelletizing, granule, at drying tower, arranges 80 DEG C of drying and then carries out packing, temporarily depositing with vacuum aluminium plastic bag for more than 2 hours
Put；
2) prepared by finished product:
2.1) silane coupler, crosslink agent DCP, antioxidant 300 are proportionally mixed, after mixing, become silane adjuvant,
It 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, catalysis masterbatch are drawn in double conical rotary vessel in proportion, then that lid is airtight,
Open double conical rotary vessel to be dried, mix；
2.4) above dry materials, mixing 2.5 hours after, by liquid spraying device, standby silane adjuvant is joined material
In；
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, being mainly used in setting up aerial wire transfer electricity consumption, insulating properties are better than PVC,
And PVC electric wire aging etc. on fire when can release toxic and harmful, and silane Insulation Material is nontoxic.
