Description

High-speed drawing liquid for preparing MT-grade tire steel cords with low die consumption, strong corrosion resistance and high cleanness
Technical Field
The invention relates to a high-speed drawing liquid for preparing a tire steel cord.
Background
The steel cord is an important part of radial tire of automobile, and is formed by wet drawing brass-plated high-strength steel wire at high speed (25-50 m/s) in a water tank drawing machine. According to the difference of the tensile strength, the 2.0-5.0 mm steel cord is divided into N grade, H grade, S grade, U grade and M grade (the tensile strength is more than or equal to 4800 MPa). The preparation of MT steel cords has extremely high requirements on drawing liquid: firstly, the wire has to have excellent lubricity and cooling property (the steel wire can be uniformly deformed only if the lubricating friction coefficient is low, and a large amount of friction heat and deformation heat can be quickly taken away only if the cooling time is fast, so that the accidental rise of the drawing temperature, the non-uniform deformation or the fracture of the steel wire can be prevented); secondly, the surface of the radial tire steel cord is plated with brass, so that the drawing liquid is required to have strong copper corrosion resistance (the corrosion resistance is poor, the surface of the steel cord is discolored in the using process, a copper layer is damaged, and the product quality is seriously influenced); and thirdly, the steel cord is compounded with the rubber tire when in use, and the steel wire of the steel cord needs to have good adhesive force, so that the matched drawing liquid needs to have high surface cleanliness of the steel cord and no residue for reducing the adhesive force exists. Since the domestic drawing liquid generally has the problems of poor lubricity, cooling property and corrosion resistance, low surface cleanliness of the steel cord, and the like, and is not seen well, the domestic market is basically monopolized by foreign brands.
