Description
Technical field:
The present invention relates to chemical technology field, be specifically related to a kind of lubricating grease for Aluminium Cable Steel Reinforced protection and preparation method thereof.
Background technology:
Aluminium Cable Steel Reinforced is by aluminum steel and steel wire is stranded forms, and is widely used in overhead transmission line.As the Aluminium Cable Steel Reinforced of electric power overhead wire leading product, be 30 years in power department life, the work-ing life of Aluminium Cable Steel Reinforced was determined by the steel core life-span, and the key addressed this problem improves the Corrosion Protection of steel core.Steel core can corrode by material effects such as moisture, chemical gas and tears in an atmosphere, and this corrosion is especially more serious in littoral industrial area.The protection on the degree of corrosion and the composition of material and surface has substantial connection.The corrosion of steel core is divided into chemical corrosion and galvanic corrosion.When atmospheric moisture is larger, steel core surface moisture can be condensed into moisture film, and the etchant gas in air such as sulfurous gas, nitrogen peroxide, hydrogen sulfide and salts substances are dissolved in moisture film, forms Thin Electrolyte Layer, reacts thus produce corrode with metal.Inner at Aluminium Cable Steel Reinforced, steel core and aluminium stock contact layer, due to electrode potential difference, also can produce crevice corrosion.After Aluminium Cable Steel Reinforced is corroded, wire obviously becomes fragile, and tensile strength obviously reduces, and can cause disconnected stock, broken string time serious, substantially reduces the work-ing life of Aluminium Cable Steel Reinforced.Therefore, in order to extend the work-ing life of Aluminium Cable Steel Reinforced, the corrosionproof protection of Aluminium Cable Steel Reinforced must be strengthened.
In order to improve the erosion resistance of Aluminium Cable Steel Reinforced, domestic and international production firm coats the anti-corrosion grease that organic materials is made usually between steel core and aluminium twist, such as Vaseline, alkyl fat, be used for stopping that moisture and corrosive gases are to the corrosion of steel core, owing to scribbling the anticorrosion grease of one deck between steel core and aluminum stranded conductor, therebetween because potential difference cause corrosion can obviously weaken.But Vaseline and alkyl fat obtain primarily of the waxed of various low melting point, so dropping point is between 50 ~ 70 DEG C, during the broiling summer, because Aluminium Cable Steel Reinforced inherently can produce certain heat, cosmoline is easy to drip from Aluminium Cable Steel Reinforced, do not have rot-resistant effect, but also add the cost of production firm, also have environment and pollute.
