スチール補強材との接着性を改良して耐久性を向上させ
ることは普遍的な要求である。Techniques for improving the strength and durability of rubber products by embedding various reinforcing materials in rubber are widely practiced. Among them, composites of rubber and steel reinforcement are applied to automobile tires, high-pressure rubber hoses, conveyor belts, etc., and the required quality performance is also diverse. Improving is a universal requirement.

望の達成のためにスチールコードとゴムとの接着性を改
良することが極めて重要な問題となっている。In particular, in steel radial tires using a steel cord plated with a copper-zinc binary alloy as a reinforcing material, there is a strong demand for increasing the high-speed durability and high-speed stability of tires with the development of highways, Improving the adhesion between steel cord and rubber has become a very important issue in order to achieve this demand.

分満足すべき状態になっていないのが現状である。Regarding this adhesiveness, research on improvement of steel wires, steel cords and rubber has been carried out, and the adhesiveness at the time of rubber product production, so-called initial adhesiveness, is being improved, but it is actually used under severe conditions. And good initial adhesiveness gradually decrease, and the present situation is that the state is not sufficiently satisfactory.

の改善が切望されている。For example, in steel radial tires, steel cords and rubber can be stored for a long time in a humid atmosphere before being mounted on a car, or when the rubber is scratched when used after being mounted on a car and water infiltrates, The problem is the so-called moisture-resistant adhesiveness, which lowers the adhesiveness of, and this improvement has been eagerly sought.

なり、初期接着性が低下する。Conventional steel wire and steel cord for rubber articles, after copper-zinc binary alloy plating on the rope,
Draw wire and even twisted wire are generally used, and in order to improve moisture resistance adhesiveness, lower the copper content of copper-zinc binary alloy plating, or nickel to copper-zinc,
Ternary alloy plating to which one of cobalt, iron and tin is added, or reduction in the thickness of a plating layer has been performed. However, the copper content is 62%
If the temperature is lowered below, the β phase is precipitated, so that the wire drawing workability is deteriorated, and wire drawing troubles such as thinning and disconnection are liable to occur. Therefore, the limit value of the copper content is about 62%. On the other hand, in the case of ternary alloy plating in which one of nickel, cobalt, iron and tin is added to copper-zinc, a uniform alloying treatment by heat diffusion is necessary. Takes a long time to reduce productivity
It is desirable to make it as thin as possible. However, if the thickness of the plating layer is too small, the peeling of the plating during wire drawing increases, and the initial adhesion decreases.
このような伸線中の問題があり、充分満足できる耐湿
接着性を得るに至っていない。There is such a problem during wire drawing, and it has not yet been possible to obtain a sufficiently satisfactory moisture resistance.

うに、表面凸部のメッキ2が剥離している。The present inventors, in order to elucidate the cause of increased plating peeling during wire drawing when the thickness of the plating is reduced, in order to elucidate the plating adhesion state to the wire rod for each wire drawing die in the wire drawing process. Upon microscopic observation, it was found that the smoothness of the wire surface before drawing affected the plating adhesion state, and that if the smoothness was poor, local plating peeling was likely to occur. FIG. 1 is a cross-sectional view showing the state of plating adhesion in the conventional method.
FIG. 3 shows an example examined by SEM (scanning electron microscope) observation. Wire 1 which is the plating base before wire drawing
Is very poor in smoothness as shown in (a) of the figure, and when this is drawn, the plating 2 on the surface convex portion is peeled off as shown in the figure (b). I have.

がっていた訳である。It was also found out that the wire had poor surface smoothness, that is, large irregularities had already occurred before the plating step. However, the conventional plating pre-treatment step was performed to remove scale or activate the surface. Surface roughness is little effective in improving surface roughness and the average surface roughness is 2 μm
Larger than above, 2 to 5 μm for wire rods with a wire diameter of 1.0 to 1.6 mm
This is the reason for the local peeling of the plating in the wire drawing process.

い出し、この発明を完成するに至ったものである。The present inventors consider that it is effective to newly add a smoothing treatment of a wire surface by electrolytic polishing to a pretreatment step of plating in order to suppress plating peeling in a wire drawing step from the above circumstances. As a result of thinking and conducting it, it was found that even if the thickness of the plating was reduced, there was almost no peeling of the plating during wire drawing, and it was possible to improve the moisture resistance adhesion without lowering the initial adhesion, The present invention has been completed.

Electropolishing is performed with an aqueous solution containing phosphoric acid as a main component and sulfuric acid or chromic acid mixed therein to reduce the average roughness of the wire surface to preferably 1 μm or less. Thereafter, on the surface of the smoothed member, copper-zinc binary alloy plating, so that the plating thickness in the final product is maintained at 0.05 to 0.20 μm, that is, the plating layer thickness represented by the following formula: Alternatively, ternary alloy plating in which one of nickel, cobalt, iron, and tin is added to copper-zinc is applied.

キしたのち、伸線加工に伴うメッキ層厚さの変化調査に
より得られたものである。The reason why the roughness is preferably 1 μm or less is that if the roughness is larger than 1 μm, a local plating peeling phenomenon easily occurs when wire drawing is performed with a reduction in area of 80% or more to obtain a predetermined tensile strength. This is because it is difficult to reduce the thickness to 0.20 μm or less. Also, set the thickness of plating after wire drawing to 0.
The reason for keeping at 0.05 to 0.20 μm is that if it is larger than 0.20 μm, almost no improvement in moisture resistance is seen, while if it is smaller than 0.05 μm, the amount of adhesion reaction with rubber is insufficient and initial adhesion is reduced. I do. Next, the calculation formula (1) for defining the plating thickness in the plating step is obtained by examining the change in the thickness of the plating layer accompanying the wire drawing after plating on the surface of the wire smoothed by electrolytic polishing. is there.

法での局部的なメッキ剥離現象は観察されない。As described above, when a wire surface smoothing process by electrolytic polishing is added as a pretreatment for plating, the flow of plating into concave portions in the drawing step after plating is reduced, and the state of plating adhesion on the entire surface is more uniform. It is maintained in a state. FIG. 2 shows an example in which the plating state in the method of the present invention is examined by SEM observation. After the wire drawing (b in the same drawing), the plating 2 is uniformly adhered to the surface of the wire 1 in the same manner as before the wire drawing (a in the same drawing), and the local portion according to the conventional method shown in FIG. No typical plating peeling phenomenon is observed.

以下に、この発明のより詳細な実施例を挙げる。 Hereinafter, more detailed embodiments of the present invention will be described.
