本発明はプラスメッキされたタイヤフードの表面の酸化

法に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of manufacturing a tire cord that prevents oxidation of the surface of a plus-plated tire hood and improves its adhesion to rubber.

−拡散によりプラスメッキとする拡散方式の２通りがあ
るが、最近では接着特性の多様化と公害の問題から拡散
方式が採用されている。Conventional technology and its problems The general manufacturing process for tire cords involves repeating wire drawing and heat treatment, then a plus plating and wet wire drawing process, and then a twisting process in which multiple wires are made into a hood. It is something that can be reached. In addition, each plate is plated with 1 piece of lead.
- There are two diffusion methods that produce positive plating through diffusion, but recently the diffusion method has been adopted due to the diversification of adhesive properties and the problem of pollution.

製品規格において付着物の麓が限定されている。また、
油塗布量を出来るがぎり減すために素線５本の内、例え
ば１〜２本のみに油塗布を行っていた。In order to satisfy the adhesion properties required by tire manufacturers, the heating temperature during diffusion is changed to control the composition of the outermost surface 150A, which most affects adhesion. Since oxidation has the most negative effect, the wire is coated with oil in the final twisting process to prevent oxidation. The larger the amount of oil applied, the better for stabilizing the S twist shape and kinks, but it has the disadvantage of weakening the rubber during adhesion, and when the tire cord is made into a sheet in the subsequent calendering process, oil adheres to each roller, making it difficult to work. Due to problems such as deterioration of the product's appearance, product standards limit the area at the base of the deposit. Also,
In order to reduce the amount of oil applied as much as possible, oil was applied to, for example, only one or two of the five wires.

ミＬコードの最も重要な接着特注が悪くなるという問題
がある。However, moisture and lubricant naturally adhere to the surface of the strands after wet wire drawing in the previous process, and the strands are rolled onto the reel in this state, but before they are twisted onto the reel, It is left for a while for 1 to 2 days, and then coated with oil using a twisting machine.During this time, the outermost surface of the 4N wire is oxidized by moisture and a 4X"1 lubricant, which is the most important adhesion for the 1mm L cord. There is a problem with custom orders going bad.

た０、２８φの８８１が通過し巻取られる。Degree of alloying: As determined by X-ray measurement, the 1.40φ wire 1 after plating is 3.5% as determined by X-ray measurement. In the process of drawing wire with a die 3 at a speed of 1000 ψin to 0.28 φ, process oil 6 placed in a container between the take-up capstan 4 and the dancer roller 5 is drawn using a cotton string 7 according to the capillary principle. It is immersed in felt 8, through which the drawn wire 881 of 0.28φ passes and is wound up.
