Steel tire cord improved in corrosion-resistance and its production method

摘要

The present invention relates to a steel tire cord having improved corrosion resistance and a method of manufacturing the same.;Steel tire cord of the present invention is coated with a 0.01-0.5% by weight solution of 8-azadene (azaadenine) on the surface of the steel tire cord or the plated layer of the filament constituting the steel tire cord and dried 8-azadenine (hereinafter referred to as' azadenine There is a technical characteristic in forming the coating layer.;In the manufacturing method of the present invention, a wire, such as a filament or a steel tire cord, is pre-wound when a steel plate is manufactured by drawing a brass plated steel wire and filaments constituting a steel tire cord for reinforcing tires or a plurality of filaments. The 8-Azadenine solution was deposited on the surface of the brass plating layer of the wire by depositing in the denin solution, and the 8-Azadenine solution coating layer was dried with hot air of 200 ° C. or higher to form an 8-Azadenine coating layer, and then wound up. It consists of a series of processes, in the case of a steel tire cord may be applied a method of applying the 8- azadenine solution in addition to the above-described drip equation.;The azadenine coating layer formed on each filament constituting the steel tire cord of the present invention or on the outer circumferential surface of the steel tire cord as a whole may improve the corrosion resistance of the steel cord even by using a low concentration solution, which may be effective in extending the life of the tire. In addition, especially in the case of exports that are stored for a long time or are transported for a long time due to exposure to the air, the 8-Azadenine solution can be effectively coated to increase the concentration of the 8-Azadenine to effectively suppress the surface degradation of steel cord products. There is this.
