Abstract
The invention discloses a low-cost cable filler and a preparation method thereof. The filler is prepared by mixing a composition raw material polyethylene resin, EVA, polyamide resin, a silane coupling agent, calcium carbonate, diatomite, titanate, zine stearate, ethyl acetate, attapulgite, fatty acid ester, straw ash, carbon black, epoxypropane phenyl ether and an antioxidant 1010 according to a certain ratio. The low-cost cable filler is stable in chemical structure, not decomposed by microorganisms, good in gel performance, and high in expansion capability, improves electrical performance of the cable, prolongs service life of the cable and saves resources.
Description
Technical field
The present invention relates to cable and use the auxiliary material field, be specifically related to a kind of low-cost electric cable stopping composition and preparation method thereof.
Background technology
Very general of the application of China's high voltage power cable and extensively is 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 strong migration and electric field energy is converted into kinetic energy and heat energy, obtains the water molecules of huge energy in the inner strenuous exercise of insulation.When the water molecules energy is enough to interrupt cable insulation XLPE molecular chain, will be at the trickle crackle of the inner generation of insulation, near the strain of the XLPE insulation the conductor will increase, and in the bigger zone of strain (locating as 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 exploitation is with vertical waterproofing type packing material, mainly be by in cable stranding process, vertically filling the water blockoff strip material, can absorb big water gaging, the turgidity height, and under heat effect, have 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.
