の構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pneumatic tire employed in a vehicle, particularly an automobile, or a tire employed in an aircraft.
When using high-strength metal ultrafine wires of 0 μm or less as reinforcing fibers, the activity of the nuclide thin wires themselves can be suppressed to prevent burnout and disconnection when the nuclide thin wires are twisted or woven, and can also be reinforced. The present invention relates to a structure of an ultra-fine wire that can improve processability when forming cords and auxiliary woven fabrics, and improve adhesion and adhesion between the ultra-fine wires when they are embedded in rubber.
例えば、自動車に採用される空気入りタイヤ用補強繊維
としては、従来、アラ壽ド繊維等の化学繊維、あるいは
金Ｉ！＄４１維が用いられており、これらの補強繊維を
ラジアル方向又はバイアス方向に配列してマトリックス
ゴム材を強化するようにしている。For example, the reinforcing fibers for pneumatic tires used in automobiles have conventionally been chemical fibers such as Arajudo fibers, or gold I! $41 fibers are used, and these reinforcing fibers are arranged in the radial direction or bias direction to strengthen the matrix rubber material.
ところで上記タイヤに採用される補強繊維は、その用途
からして、できるだけ引張強度が高いこと、またできる
限り軽量化することがその性能面において要請されてお
り、そのためには線径１６０μ信以下の高強度の金属極
細線で補強繊維を構成するのが望ましい。By the way, the reinforcing fibers used in the above-mentioned tires are required to have as high a tensile strength as possible and to be as lightweight as possible due to their use. It is desirable that the reinforcing fibers be made of high-strength metal ultrafine wires.
ところが、本件発明者等の実験研究により、線径１６０
μｍ以下の金属極細線を採用する場合、以下の問題を解
決しなければならないことが判明した。However, through experimental research by the present inventors, wire diameter 160
It has been found that when employing ultrafine metal wires of micrometers or less, the following problems must be solved.
ｉ、金属線を１６０μｍ以下に極細化すると、ボリュー
ムに対する表面積の比が極めて大きくなることから、該
極細線の表面の活性度が異常に高くなり、その結果極細
化する際のダイスとの摩擦。i. When a metal wire is ultrafine to 160 μm or less, the ratio of surface area to volume becomes extremely large, so the surface activity of the ultrafine wire becomes abnormally high, resulting in friction with the die during ultrathinness.
あるいは撚り線化する際の極細線同士の摩擦による発熱
により、極端な場合は焼失あるいは断線するおそれがあ
る。従って極細線自体の活性度を抑制する必要がある。Or, in extreme cases, there is a risk of burnout or disconnection due to heat generation due to friction between the ultra-thin wires when they are twisted into wires. Therefore, it is necessary to suppress the activity of the ultrafine wire itself.
ｉｉ 、また、極細化する際の伸線加工を容易化にする
ため、及び撚り線加工等の加工性を確保するために極細
線自体に自己潤滑性を付与する必要がある。ii. Furthermore, in order to facilitate the wire drawing process when making the wire ultra-thin, and to ensure workability such as wire stranding, it is necessary to impart self-lubricating properties to the ultra-fine wire itself.
市、さらに、上記極細線は鯛であるがら錆が発生し易く
、しかも極細であるから錆びが発生するとその影響が大
きく、致命的に特性が悪化する。Furthermore, although the above-mentioned ultra-fine wire is a sea bream, it is easy to rust, and since it is extremely fine, if rust occurs, the effect is large and the characteristics are fatally deteriorated.
従って鯖の発生を防止するため耐蝕性を付与する必要が
ある。Therefore, it is necessary to provide corrosion resistance to prevent the occurrence of mackerel.
１ｖ、さらにまた、上記極細線をタイヤ本体のゴム材内

細線の特性を有効に作用させることができないおそれが
あるからである。Furthermore, when the ultrafine wire is embedded in the rubber material of the tire body, it is necessary to improve the adhesion and adhesion between the two. This is because if the adhesion is insufficient, the ultra-fine wire may come off from the resin due to tension or twisting, and the characteristics of the ultra-fine wire may not be utilized effectively.
本発明の目的は、線径１６０μ醜以下の金属極細線を採

ンレス線程度である。Reasons for using stainless steel wire or low carbon dual-phase steel wire The ultra-fine wire that makes up the reinforcing fibers has excellent tensile strength to withstand the displacement between the matrix rubber and the reinforcing fibers that occurs when the tire rubs against the road surface. , and the wire diameter must be 160 μm or less to contribute to weight reduction.
To meet these requirements, piano wire, stainless steel wire, or low carbon duplex & 1lra steel wire is optimal. Here, when a low carbon dual-phase steel wire is used as the ultra-fine wire, the tensile strength can be improved without making the wire diameter even smaller than that of a piano wire or the like. This low carbon two-phase &l weave single wire was researched and developed by the inventors of the present invention. It was completed by discovering the following points. ! A composite metal Mi woven fabric made of a F6-C-31-Mn iron-based alloy, in which a low-temperature transformation phase consisting of acicular martensite, bainite, or a mixed structure thereof is uniformly dispersed in a ferrite phase. 11M
The material is excellent in strong processing, and by using a wire having such a metallographic structure, it is possible to easily and reliably obtain an ultra-fine wire with a wire diameter of 100 μm or less by cold wire drawing. If such a tI4wA material is strongly worked to a working strain of 4 or more by cold wire drawing, a uniform composite &l1m <two-phase structure consisting of the above-mentioned ferrite phase and low-temperature transformation generated phase extending in one direction will be formed. A fibrous fine metal structure is formed, and such metal &

いることを見出した。Such a fibrous fine metal wire has a completely new structure that has not been known in the past.From the viewpoint that the above-mentioned metal weave is the main reason for improving tensile strength, the inventors of the present invention
As a result of further research into the strengthening mechanism,
In the metal M-weave having ultra-high strength as described above, the spacing between the fibers is 50-1000, and the composite M-weave in the fibrous form is composed of ultrafine cells of 5-100. I found out.

0% or less, Mrz 5.0% or less, the balance is Fe and unavoidable impurities, and the wire diameter is 3.5n or less.
After being heated to a temperature in the range of 00°C, it is cooled (this heating and cooling may be performed multiple times) to produce a low-temperature structure consisting of martensite, bainite, or a mixed structure thereof that may contain some residual austenite. A wire rod having a composite vA weave in which a transformation phase is uniformly dispersed in a ferrite phase at a volume percentage of 15 to 75% is manufactured. The above-mentioned manufacturing method is described in Japanese Patent Laid-Open No. 62-20824.

も低い。By increasing the degree of processing in this way, the fibrous structure becomes finer and the fiber spacing becomes narrower, and finally, as mentioned above, the cell size and fiber spacing produced during processing are 5 to 100 and 50 to 50, respectively. It becomes a fibrous fine metal structure with a thickness of ~1000. In addition, in the wB wire obtained by wire drawing with a processing strain of 4 or less, the fibrous structure is in the middle of development and the structure is incomplete, and therefore the strength is low.

As is clear from the same table, which shows a comparison of decorative properties and conductivity, Ni has high self-lubricating properties, which can improve die life, and has high corrosion resistance such as rust prevention and prevention of 3M. In addition, it has excellent adhesion to matrix resin or matrix rubber, and also has high surface treatment properties.It can be seen that Nl is the most excellent both overall and from the above-mentioned characteristics. Therefore, it can be seen that the above-mentioned 1-1v problem can be solved by coating with Nl.

しくない。Alternatively, N1 plating alloyed with other metals is also included. Regarding the coating amount of Nl on the above-mentioned ultra-fine wire, if it is less than 1 g per ultra-fine wire, it is difficult to exhibit the above-mentioned coating effects such as rust prevention effect, and even if it exceeds 100 g, no improvement in the coating effect can be expected. On the contrary, it is not preferable because it causes secondary disadvantages such as powdering during processing due to thick coating.
従って、極細線１ ｋｇ当たり１〜１００ｇの範囲内が
適当である。Therefore, a range of 1 to 100 g per 1 kg of ultrafine wire is appropriate.

Reason for imparting processing strain by plastic working to the Ni-plated coating layer When the present inventors further investigated the above-mentioned Nt-plated coating layer, they found that the condition of the Ni-plated coating layer was sufficiently satisfactory. Adhesion.
接着性が得られない場合があることが判明した。It has been found that adhesion may not be obtained in some cases.
この理由は明確ではないが以下の点が考えられる。Although the reason for this is not clear, the following points can be considered.

悪影響を与えているものと考えられる。In other words, the Ni plating coating layer that has just been plated has a porous shape with countless pinholes, and therefore hydrogen generated during the plating process is stored in the Ni coating layer or in the porous layer. Air will remain. It is thought that this occluded hydrogen and residual air are released or expanded by some kind of heat and accumulate at the boundary between the rubber and the N1 coating layer, resulting in a negative impact on the adhesion and adhesion between the two. .

In the case where four ultra-fine wires of When coated with resin (N13)
A pull-out test was conducted on the case where only Ni plating was applied (base 4). We also adopted an ultra-fine wire with a wire diameter of 100 μm, which was also coated with Nl plating (Ilh
5), and a similar pullout test was also conducted for the case where processing strain was applied by wire drawing (Hiroshi 6).
In the table, an x mark indicates a case where the ultra-fine wire a has come off from the composite sample piece, and an ○ mark indicates a case where the ultra-fine wire a is broken.
表からも明らかなように、線径５０μｍでＮｌめっきを
被覆しない場合（Ｍｌ）は抜けており、両者の接着力は
上記極細線の破断力未満であった。As is clear from the table, in the case where the wire diameter was 50 μm and Nl plating was not covered (Ml), the adhesive strength between the two was less than the breaking force of the ultrafine wire.
これに対して、Ｎｉめっきを被覆しくＮ１４）、さらに

ることがわかる。On the other hand, when the Ni plating was coated (N14), the Ni plating was subjected to processing strain (2), and the resin was coated (3), the wire broke before it came out, and both It can be seen that the adhesive force of is greater than the breaking force of ultra-fine wire.
一方、線径１００ ｐ−でＮ１めっき被覆層を形成した
だけの場合（ｌｌＩａ５）は、断線する前に抜けている
。これは線種が大きい置引張力も高いことから、接着力
がこの高い引張力には及ばなかったものと考えられる。On the other hand, in the case where the wire diameter is 100 p- and only the N1 plating layer is formed (llIa5), the wire comes off before it breaks. This is probably because the adhesive force was not as high as this high tensile force because the wire type had a high tensile force.

の場合も略同様の効果が得られる。However, when processing strain was applied to this wire (Na6), the wire broke, which explains why processing strain improves adhesive strength, and in the case of relatively thick vAPk, the tensile force of the ultra-thin wire itself increases. Therefore, it can be seen that by applying processing strain, an adhesive force that can cope with this large tensile force can be obtained, and the effect is even greater. In addition,
Although resin was used in this experiment to determine the adhesive force effect, substantially the same effect can be obtained using rubber.
