Problems solved by technology

At present, none of the metal-coated steel wires can meet the requirements. First, the corrosion resistance of the existing metal coatings is only relative to that of galvanizing. Second, the temperature of the molten alloy in the production process leads to a decline in the mechanical properties of the dip-coated steel wires.

Abstract

The invention discloses a steel-cored wire to transmit electric power and organosilicon paint of strand cable wire, which comprises the following steps: allocating 15-35% organosilicon resin, 65-85% solvent, 0.15-1.5% hardener and 1.0-3.0% toughening agent, wherein the organosilicon adopts polysiloxane or polyfunctional hydrolytic silane modified organic resin; the solvent is selected from alcohol compound such as alcohol, butanol and so on or other ester, benzene and ketone solvents; the hardener can be triethylene tetramine or tetraethylene pentamine; the toughening agent is phthalandione dibutyl vinegar or phthalandione dioctyl, which can be added with fitful quantity of inhibitor to lengthen the using time of organosilicon paint during coating stage.

Description

technical field [0001] The invention relates to a composition of organosilicon coating for steel core wires and stranded steel wires used for electric power transmission. Background technique [0002] Steel core wires and stranded steel wires used for power transmission must have good corrosion resistance and high mechanical properties. At present, none of the metal-coated steel wires can meet the requirements. One is that the corrosion resistance of the existing metal coatings is only relative to that of galvanizing, and the other is that the temperature of the molten alloy in the production process reduces the mechanical properties of the dip-coated steel wire. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects, and provide a steel core wire and stranded steel wire silicone coating composition for power transmission. [0004] The technical solution of the present invention is: a steel core wire and stranded ...
