[0002] Steel cord is made of high-quality high-carbon steel with brass-plated surface and has special-purpose fine-gauge steel wire strands or ropes. With the development of steel cord in the direction of lightweight, the amount of steel wire in tires is gradually reduced. Therefore, improving the strength of steel wire and the surface quality of steel wire has become the most concerned issue for steel cord manufacturers. At present, domestic wire drawing powder is difficult to meet the production of steel cord. The surface of steel wire after production is prone to scratches, which seriously affects the surface of steel wire. quality

Embodiment 1
[0022] The preparation method of the wire drawing powder that is used for steel cord of the present embodiment, comprises the following steps:
[0023] According to mass percentage, provide 50% stearic acid, 20% sodium hydroxide, 9% sodium nitrate, 20% water; mix sodium hydroxide, sodium nitrate, sodium nitrate and water and pour In the kneader, set the oil temperature to 180°C, the material temperature to 100°C, and stir and mix for 20 minutes to obtain a premix; when the premix reaches 80°C, add stearic acid and fully stir for 2 hours to obtain a mixture; When the mixture reaches 100°C, reduce the oil temperature to 110°C, continue to stir for 8 hours, turn off the heating, cool it out of the pot, and get wire drawing powder for steel cords.
Embodiment 2
[0025] The preparation method of the wire drawing powder that is used for steel cord of the present embodiment, comprises the following steps:
[0026] In terms of mass percentage, provide 80% stearic acid, 8% sodium hydroxide, 5% sodium nitrate, 5% water; mix sodium hydroxide, sodium nitrate, sodium nitrate and water and pour In the kneader, set the oil temperature at 190°C and the material temperature at 110°C, and stir and mix for 30 minutes to obtain a premix; when the premix reaches 90°C, add stearic acid and fully stir for 2 hours to obtain a mixture; When the mixture reaches 110°C, reduce the oil temperature to 110°C, continue to stir for 8 hours, turn off the heating, cool it out of the pot, and get wire drawing powder for steel cords.
Embodiment 3
[0028] The preparation method of the wire drawing powder that is used for steel cord of the present embodiment, comprises the following steps:
[0029] According to mass percentage, provide 70% stearic acid, 17% sodium hydroxide, 5% sodium nitrate, 5% water; mix sodium hydroxide, sodium nitrate and water and pour In the kneader, set the oil temperature to 200°C, the material temperature to 110°C, and stir and mix for 30 minutes to obtain a premix; when the premix reaches 90°C, add stearic acid and fully stir for 3 hours to obtain a mixture; When the mixture reaches 110°C, reduce the oil temperature to 120°C, continue to stir for 12 hours, turn off the heating, cool it out of the pot, and get wire drawing powder for steel cords.

Abstract
The invention discloses wire drawingpowder for a steel cord and a preparation method thereof. The preparation method of the wire drawingpowder for the steel cord comprises the following steps that (1) the oil temperature and the material temperature are set; (2) sodiumhydroxide, sodiumsilicate, sodiumnitrate and water are added, stirred and mixed; and (3) stearic acid is added, stirred and mixed, and then discharging is conducted. According to the prepared wire drawingpowder for the steel cord, the stearic acid serves as a lubricating agent, the good lubricating property is achieved, a lubricating film can be formed between a drawn metal wire and the die wall of a wire drawing die, force energy consumption during drawing and friction between interfaces are reduced, and the wire drawing speed is effectively increased; and the stearic acid can wrap the surfaces of solid particles, the situation that the surfaces of steel wires are scratched by the solid particles in the wire drawing process is prevented, scratches on the surfaces of the steel wires are reduced, and the surface quality of the steel wires is improved.
