Abstract
The invention discloses an environment-friendly cable filler and a preparation method thereof. The environment-friendly cable filler is prepared mainly by mixing polrvinyl chloride resin, phenolic resin, polypropylene, triallyl cyanurate, sillicane coupling agent, titanate, zinc oxide, straw ash, graphite, calcium carbonate, anti-aging agent, flame retardant and lead silicate in a certain mixture ratio. The environment-friendly cable filler has the advantages of stable chemical structure, good gelation performance and strong expanding capability, and cannot be decomposed by microorganisms; the electrical performance of a cable is improved; the service life of the cable is prolonged; and the resources are saved.
Description
Technical field
The present invention relates to cable and use the auxiliary material field, be specifically related to a kind of environment-friendly cable stopping composition and preparation method thereof.
Background technology
The application of China's high voltage power cable very general with extensively, comparatively moist mostly at high voltage power cable underground its environment that is laid in mostly.The very easy construction of cable inside that is penetrated into of moisture. therefore the electric stress theory is thought under normal high pressure energising situation, and the internal stress of cable in production and operational process is the major cause that promotes the water tree growth.When cable when standing voltage and water, in the high pressure power frequency electric field, polar water molecules produces the intensive migration and electric field energy is converted into kinetic energy and heat energy, the water molecules that obtains huge energy is in the inner strenuous exercise of insulation.When the water molecules energy is enough to interrupt cable insulation XLPE molecular chain, will produce trickle crackle in that insulation is inner, near the XLPE insulating strain the conductor will increase, and in the bigger zone of strain (locating) like impurity and pore etc. just generate water tree.Reduce the dielectric level of insulating material greatly, thereby shortened the work-ing life of cable, cause enormous economic loss.
The cable of my company's exploitation is with vertical waterproofing type packing material; Mainly be through in cable stranding process, vertically filling the water blockoff strip material; Can absorb big water gaging, turgidity is high, and under heat effect, has higher gel viscosity and enough resistance toheats; And be convenient to the convenient of cable production industry and use, this material have the steady chemical structure that realizes the cable water shutoff material, not good by microbiological degradation, gellifying property, certain swelling capacity and speed of expansion requirement arranged.
Summary of the invention
For deficiency and the defective of alleviating prior art; The invention discloses a kind of environment-friendly cable stopping composition and preparation method thereof; Environment-friendly cable stopping composition of the present invention has steady chemical structure, not good by microbiological degradation, gellifying property, and swelling capacity is high, and the electric property of cable improves; Prolong the work-ing life of cable, practiced thrift resource.
The technical scheme that adopts for the present invention of realization above-mentioned purpose is following:
The environment-friendly cable stopping composition is characterized in that the weight part of its constitutive material is:
Described environment-friendly cable stopping composition is characterized in that: described anti-aging agent is an antioxidant 4010; Described fire retardant is selected from a kind of or mixture in Marinco H or the white lake.
The preparation method of described environment-friendly cable stopping composition is characterized in that may further comprise the steps:
(1) weight part by constitutive material takes by weighing each raw material, mixes, and the extruder hopper of packing into, the barrel zone temperature of extruding machine are controlled at 130-190 ℃, generates the molten state compound;
(2) in the molten state compound, pour nitrogen, take out and pass through 75-95 ℃ hot water tank and room temperature tank, the air-dry finished product that obtains successively.
Beneficial effect of the present invention:
Environment-friendly cable stopping composition of the present invention has steady chemical structure, not good by microbiological degradation, gellifying property, and swelling capacity is high, and the electric property of cable improves, and has prolonged the work-ing life of cable, has practiced thrift resource.
