Abstract
The invention provides a special compound for a flame retardant cable filled with and modified by 6,000-mesh ultrafine heavy calcium carbonate. The special compound for the flame retardant cable filled and modified by the 6,000-mesh ultrafine heavy calcium carbonate is characterized in that the special compound for the flame retardant polyvinyl chloride insulated cable is prepared by adopting proper raw materials, adding an appropriate stabilizing agent, and combining a resin, a plasticizer, the stabilizing agent, a filler, an antioxidant, a lubricating agent, a coloring agent and the like together by using a double screw extruder. The special compound for the flame retardant polyvinyl chloride insulated cable provided by the invention has excellent electrical insulating property, processing performance and heat stability. A good surface can be obtained by a common screw extruder. The special compound for the flame retardant polyvinyl chloride insulated cable fits the technical conditions of TLJ-98-03, and is suitable for power cables, cables for building electrical equipment, automotive wiring harness and the like which have requirements for flame resistance.
Description
Technical field the present invention relates to polymer modification technology, especially material special for flame-retarding polyvinyl chloride insulated cable.
Background technology polyvinyl chloride resin has difficult combustion, oil resistant, chemical resistance corrosion, the characteristics such as water-fast, has simultaneously the advantages such as physical and mechanical properties is good, electrical property is good, is the comparatively desirable coating material of wires and cables industry; But the PVC material exists temperature tolerance, weathering resistance, wear resistance relatively poor, in use procedure softening agent separate out shortcomings such as making the material aging degradation, make the PVC material be difficult to adapt to current environmental requirement.
General polyvinyl chloride resin has excellent electrical insulating property.This resin adds in hot briquetting and easily causes man-hour take dehydrochlorination as main thermolysis, and the electrical insulating property that therefore causes fabricated product reduces, and mechanical property is therefore aging and reduce, and also has the bad shortcoming of tone.In order to overcome this shortcoming, add one or more thermo-stabilizer in polyvinyl chloride resin in the past, suppressed the thermal ageing of this manufacturing procedure, for this purpose, can use the stablizers such as lead compound, so but could not reach better electrical insulating property and processibility.
In order to improve the performance of insulated cable material, need add suitable properties-correcting agent to improve electrical insulating property, processibility and thermostability.
Summary of the invention the invention provides a kind of material special for flame-retarding polyvinyl chloride insulated cable: model ZJ-70, ZJR-70, ZJ-90, ZJ-105.It is 2 type PVC polymkeric substance, multipolymer or blend high-quality resin that this insulated cable PP Pipe Compound adopts polyvinyl chloride, three salt are plumbous, the organic phosphoric acid metal salt compound is stablizer, trimellitic acid 1,2-anhydride, Di Iso Decyl Phthalate are softening agent, calcium carbonate, clay are weighting agent, and BaSt, ZnSt are lubricant, and dihydroxyphenyl propane is oxidation inhibitor, carbon black is tinting material, by warp pair rank twin-screw mixer extruding pelletization, it has good physicochemical property and excellent processing characteristics, meets the TLJ-98-03 technical qualification.
The consumption umber that adds auxiliary agent in material is:
| Polyvinyl chloride resin | 100 |
| Softening agent | 35～50 |
| Stablizer | 6～10 |
| Lubricant | 0.5～1 |
| Weighting agent | 5～25 |
| Tinting material | 0.05～0.15 |
Embodiment
Further illustrate by the following examples the present invention:
The material special for flame-retarding polyvinyl chloride insulated cable formula (unit: wt%):
| Polyvinyl chloride resin | 100 |
| Softening agent, trimellitic acid 1,2-anhydride and phthalic acid two isodecyl vinegar | 30 and 20 |
| Stablizer, three salt lead and organic phosphoric acid metal salt compounds | 7 and 0.1 |
| Lubricant, BaSt and ZnSt | 0.5 and 0.2 |
| Weighting agent, calcium carbonate and clay | 15 and 10 |
| Tinting material, carbon black | 0.1 |
| Oxidation inhibitor, dihydroxyphenyl propane | 0.5 |
The screen cloth of polyvinyl chloride resin powder by certain order number sieved, to remove mechanical impurity and flake etc. in resin.Stablizer, lubricant, softening agent, weighting agent etc. are stirred, grind and filter to get slurry.With softening agent, pigment is infiltrated, stir, grind, pigment is fully disperseed, to improve its tinting strength.Add two rank dual-screw pelletizer group to plastify granulation in the polyvinyl chloride resin that measures, mill base, the slurry that is mixed with etc. at last.
Its extruding-out process (temperature ℃) parameter:
| 1 section | 2 sections | 3 sections | 4 sections | 5 sections | Head | Die orifice | |
| Temperature, ℃ | 135 | 145 | 155 | 165 | 170 | 175 | 180 |
Annotate: above parameter is only for reference, and the structure that concrete temperature is looked equipment adjusts accordingly.
The flame-proof polyvinyl chloride insulated cable that the inventive method is made has excellent performance, meets the TLJ-98-03 technical qualification.Its performance index are as follows: (1) tensile strength MPa/25.8, (2) elongation at break %/228, (3) thermostability (180 ℃)/180 minutes, (4) volume resistance (Ω m)/1.85 * 10
12.。
The above, it is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
