Description

本発明は、タイヤ内表面に吸音材を配置した空気入りタイヤ及びその製造方法に関し、さらに詳しくは、吸音材の接着性を改善する共に、生産性を向上することを可能にした空気入りタイヤ及びその製造方法に関する。   The present invention relates to a pneumatic tire in which a sound absorbing material is disposed on an inner surface of a tire and a method for manufacturing the same, and more particularly, to improve the adhesion of the sound absorbing material and improve the productivity, and It relates to the manufacturing method.

近年、空気入りタイヤにおいて、タイヤ内部に充填された空気の振動に起因する空洞共鳴音が問題視されている。この空洞共鳴音は、タイヤを転動させたときにトレッド部が路面の凹凸によって振動し、トレッド部の振動がタイヤ内部の空気を振動させることによって生じるのである。このような空洞共鳴音を低減する手法として、タイヤ内表面に吸音材を貼り付けることが提案されている（例えば、特許文献１及び特許文献２参照）。   In recent years, in a pneumatic tire, a cavity resonance sound caused by vibration of air filled in the tire has been regarded as a problem. This cavity resonance sound is generated when the tread portion vibrates due to road surface irregularities when the tire rolls, and the vibration of the tread portion vibrates the air inside the tire. As a technique for reducing such cavity resonance noise, it has been proposed to attach a sound absorbing material to the tire inner surface (see, for example, Patent Document 1 and Patent Document 2).

しかしながら、通常、空気入りタイヤはブラダーが当接するタイヤ内表面に離型剤を塗布した状態で加硫されるため、加硫後においてタイヤ内表面には離型剤が付着している。そのため、加硫後のタイヤ内表面に吸音材を貼り付ける場合、吸音材の接着性を確保するためにタイヤ内表面から離型剤を除去することが必要であり、その離型剤の除去作業が空気入りタイヤの生産性を低下させるという問題がある。
特開昭６３−２９１７０８号公報 特開２００３−６３２０８号公報 However, since a pneumatic tire is usually vulcanized in a state where a release agent is applied to the inner surface of the tire with which the bladder contacts, the release agent adheres to the inner surface of the tire after vulcanization. Therefore, when a sound-absorbing material is affixed to the tire inner surface after vulcanization, it is necessary to remove the release agent from the tire inner surface in order to ensure the adhesion of the sound-absorbing material. However, there is a problem that the productivity of the pneumatic tire is lowered.
JP 63-291708 A JP 2003-63208 A

本発明の目的は、吸音材の接着性を改善する共に、生産性を向上することを可能にした空気入りタイヤ及びその製造方法を提供することにある。   An object of the present invention is to provide a pneumatic tire and a method for manufacturing the same that improve the adhesiveness of the sound absorbing material and improve the productivity.

上記目的を解決するための本発明の空気入りタイヤは、タイヤ内表面に離型剤を塗布した状態で加硫された空気入りタイヤにおいて、離型剤が付着したタイヤ内表面にラテックスの乾燥皮膜を形成し、該ラテックスの乾燥皮膜に吸音材を貼り付けたことを特徴とするものである。   In order to solve the above-described object, the pneumatic tire of the present invention is a pneumatic tire vulcanized in a state where a release agent is applied to the inner surface of the tire, and a dry film of latex on the inner surface of the tire to which the release agent has adhered. And a sound absorbing material is attached to the dry film of the latex.

一方、上記目的を解決するための本発明の空気入りタイヤの製造方法は、タイヤ内表面に離型剤を塗布した状態で加硫された空気入りタイヤの内側にラテックスを流し込み、そのタイヤを回転させながら前記ラテックスを乾燥させることにより、離型剤が付着したタイヤ内表面にラテックスの乾燥皮膜を形成し、該ラテックスの乾燥皮膜に吸音材を貼り付ける工程を有することを特徴とするものである。   On the other hand, the manufacturing method of the pneumatic tire of the present invention for solving the above-described object is that the latex is poured inside the vulcanized pneumatic tire in a state where a release agent is applied to the inner surface of the tire, and the tire is rotated. The latex is dried while forming a latex dry film on the inner surface of the tire to which the release agent is adhered, and a sound absorbing material is attached to the latex dry film. .

本発明では、タイヤ内表面に離型剤を塗布した状態で加硫された空気入りタイヤに吸音材を付加するにあたって、離型剤を除去することなくタイヤ内表面にラテックスの乾燥皮膜を形成する。ラテックスの乾燥皮膜は、液状のラテックスをタイヤ内面に塗布し、これを乾燥させることで簡単に得られるが、その際に離型剤を除去しなくてもタイヤ内面に対して良好な接着状態となる。そのため、タイヤ内表面に形成されたラテックスの乾燥皮膜に対して吸音材を貼り付けることにより、吸音材の接着性を改善すると共に、空気入りタイヤの生産性を向上することができる。特に、ラテックスの乾燥皮膜は、空気入りタイヤの内側にラテックスを流し込み、そのタイヤを回転させながらラテックスを乾燥させることで、最も効率良く形成することができる。   In the present invention, when adding a sound absorbing material to a pneumatic tire vulcanized with a release agent applied to the inner surface of the tire, a dry film of latex is formed on the inner surface of the tire without removing the release agent. . A dry latex film can be obtained simply by applying a liquid latex to the tire inner surface and drying it. At that time, it has a good adhesion to the tire inner surface without removing the release agent. Become. Therefore, by adhering the sound absorbing material to the dry latex film formed on the inner surface of the tire, the adhesiveness of the sound absorbing material can be improved and the productivity of the pneumatic tire can be improved. In particular, the dry film of latex can be most efficiently formed by pouring latex into the inside of a pneumatic tire and drying the latex while rotating the tire.

本発明において、過度の重量増加を伴うことなく吸音材の接着状態を良好に維持するために、ラテックスの乾燥皮膜の厚さは０．０２ｍｍ〜１．０ｍｍとすることが好ましい。ラテックスとして接着性を有するものを用いた場合、吸音材をラテックスの乾燥皮膜に直接接着することが可能になる。この場合、ラテックスの乾燥皮膜と吸音材との間に他の接着剤を用いる必要がない。   In the present invention, the thickness of the dry film of the latex is preferably 0.02 mm to 1.0 mm in order to maintain a good adhesion state of the sound absorbing material without an excessive weight increase. When an adhesive having latex is used, the sound absorbing material can be directly bonded to the dry film of the latex. In this case, it is not necessary to use another adhesive between the latex dry film and the sound absorbing material.

以下、本発明の構成について添付の図面を参照しながら詳細に説明する。   Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

図１は本発明の実施形態からなる空気入りタイヤを示し、図２は本発明の実施形態からなる空気入りタイヤから吸音材を取り除いた状態を示すものである。図１及び図２において、１はトレッド部、２はサイドウォール部、３はビード部である。   FIG. 1 shows a pneumatic tire according to an embodiment of the present invention, and FIG. 2 shows a state where a sound absorbing material is removed from the pneumatic tire according to an embodiment of the present invention. 1 and 2, 1 is a tread portion, 2 is a sidewall portion, and 3 is a bead portion.

上記空気入りタイヤにおいて、タイヤ内表面４にはラテックスの乾燥皮膜５が形成されている。このラテックスの乾燥皮膜５はトレッド部１に対応する領域でタイヤ全周にわたって形成されている。そして、ラテックスの乾燥皮膜５に対して吸音材６がタイヤ全周にわたって貼り付けられている。   In the pneumatic tire, a dry film 5 of latex is formed on the tire inner surface 4. The latex dry film 5 is formed over the entire circumference of the tire in a region corresponding to the tread portion 1. And the sound-absorbing material 6 is affixed over the tire circumference with respect to the dry film 5 of latex.

次に、上記空気入りタイヤの製造方法について説明する。図３（ａ）〜（ｃ）は本発明の空気入りタイヤの製造方法を概略的に示すものである。この空気入りタイヤは、タイヤ内表面４に離型剤（不図示）を塗布した状態で加硫されたものである。加硫後、図３（ａ）に示すように、タイヤ内表面４から離型剤を取り除くことなく、空気入りタイヤの内側に流動性を任意に調整したラテックス（コロイド状分散液）５ａを流し込む。そして、タイヤ回転軸を水平方向に配置した状態で、そのタイヤを回転させながらラテックス５ａを乾燥させる。これにより、図３（ｂ）に示すように、タイヤ内表面４に均一な厚さを有するラテックスの乾燥皮膜５を形成する。   Next, a method for manufacturing the pneumatic tire will be described. 3 (a) to 3 (c) schematically show a method for manufacturing a pneumatic tire according to the present invention. This pneumatic tire is vulcanized in a state where a release agent (not shown) is applied to the inner surface 4 of the tire. After vulcanization, as shown in FIG. 3 (a), a latex (colloidal dispersion) 5a whose flowability is arbitrarily adjusted is poured into the inside of the pneumatic tire without removing the release agent from the tire inner surface 4. . And latex 5a is dried, rotating the tire in the state which has arranged the tire axis of rotation in the horizontal direction. Thereby, as shown in FIG.3 (b), the dry film 5 of the latex which has uniform thickness in the tire inner surface 4 is formed.

乾燥皮膜５の幅Ｗは、貼り付ける吸音材６に応じて任意に設定されるが、ラテックスの流し込みにより乾燥皮膜５が形成されるため、現実的にはベルト幅の７５％〜１５０％（弧長）である。また、乾燥皮膜５の厚さは０．０２ｍｍ〜１．０ｍｍの範囲にあることが好ましい。この乾燥皮膜５の厚さが０．０２ｍｍ未満であると乾燥皮膜５の強度が不十分になり、逆に１．０ｍｍを超えると重量増加が過度になる。   The width W of the dry film 5 is arbitrarily set according to the sound absorbing material 6 to be attached. However, since the dry film 5 is formed by pouring latex, it is practically 75% to 150% (arc) of the belt width. Long). Moreover, it is preferable that the thickness of the dry film 5 exists in the range of 0.02 mm-1.0 mm. If the thickness of the dry film 5 is less than 0.02 mm, the strength of the dry film 5 becomes insufficient. Conversely, if the thickness exceeds 1.0 mm, the weight increase becomes excessive.

ラテックスの乾燥皮膜５を形成した後、図３（ｃ）に示すように、乾燥皮膜５に対して吸音材６を貼り付ける。このとき、吸音材６をラテックスとは別の接着剤を用いて乾燥皮膜５に貼り付けることが可能であるが、接着性を有するラテックスを用いた場合、吸音材６を乾燥皮膜５に対して直接接着することができる。この場合、ラテックスが完全に乾燥する前に乾燥皮膜５に対して吸音材６を接着すれば良い。   After forming the latex dry film 5, a sound absorbing material 6 is attached to the dry film 5 as shown in FIG. At this time, the sound absorbing material 6 can be attached to the dry film 5 by using an adhesive different from the latex. However, when the latex having adhesiveness is used, the sound absorbing material 6 is attached to the dry film 5. Can be glued directly. In this case, the sound absorbing material 6 may be bonded to the dry film 5 before the latex is completely dried.

乾燥皮膜５に用いるラテックスの種類は特に限定されるものではないが、タイヤとの接着性を考慮すると、クロロプレンゴムのラテックスが好ましい。また、接着性を有するラテックスとして、例えば、天然ゴム（ＮＲ）のラテックスを挙げることができる。接着性を有するラテックス（常温加硫タイプ）の配合例を表１に示す。ラテックスには、他の成分として、分散剤、クリーミング剤、安定剤等を適宜添加しても良い。
The type of latex used for the dry film 5 is not particularly limited, but chloroprene rubber latex is preferred in view of adhesion to the tire. Examples of the latex having adhesiveness include natural rubber (NR) latex. Table 1 shows formulation examples of latex having an adhesive property (room temperature vulcanization type). To the latex, as other components, a dispersant, a creaming agent, a stabilizer and the like may be appropriately added.

Figure 2005271695
Figure 2005271695

一方、吸音材６の材質は特に限定されるものではないが、密度５〜７０ｋｇ／ｍ3 の多孔質材を用いると良い。多孔質材としては、樹脂の発泡体を用いることができ、特に発泡ポリウレタンフォームを用いることが好ましい。 On the other hand, the material of the sound absorbing material 6 is not particularly limited, but a porous material having a density of 5 to 70 kg / m 3 may be used. As the porous material, a resin foam can be used, and it is particularly preferable to use a foamed polyurethane foam.

上述のようにタイヤ内表面４に離型剤を塗布した状態で加硫された空気入りタイヤに吸音材６を付加するにあたって、離型剤を除去することなくタイヤ内表面４にラテックスの乾燥皮膜５を形成し、該ラテックスの乾燥皮膜５に対して吸音材６を貼り付けるので、吸音材６の接着性を改善し、しかも空気入りタイヤの生産性を向上することができる。   As described above, when the sound absorbing material 6 is added to the pneumatic tire vulcanized in a state where the release agent is applied to the tire inner surface 4, a dry film of latex is applied to the tire inner surface 4 without removing the release agent. 5 and the sound absorbing material 6 is affixed to the dry film 5 of the latex, so that the adhesion of the sound absorbing material 6 can be improved and the productivity of the pneumatic tire can be improved.

タイヤサイズ２１５／６０Ｒ１６の空気入りタイヤにおいて、吸音材の接着条件だけを異ならせた従来例、比較例１〜２及び実施例１〜２のタイヤをそれぞれ製作した。吸音材には、幅１６０ｍｍ、厚さ１０ｍｍ、密度３０ｋｇ／ｍ3 の発泡ウレタンフォームを使用し、この発泡ウレタンフォームをタイヤ全周にわたってトレッド部におけるタイヤ内表面に配置した。 In a pneumatic tire having a tire size of 215 / 60R16, tires of a conventional example, comparative examples 1 and 2 and examples 1 and 2 in which only the bonding conditions of the sound absorbing material were changed were manufactured. As the sound absorbing material, a foamed urethane foam having a width of 160 mm, a thickness of 10 mm, and a density of 30 kg / m 3 was used, and this foamed urethane foam was disposed on the inner surface of the tire in the tread portion over the entire circumference of the tire.

従来例では、加硫時の離型剤が付着したままでタイヤ内表面に吸音材を貼り付けようとしたが、結果的に吸音材が接着しなかった。比較例１では、タイヤ内表面の離型剤を水で洗浄した後、ゴム系接着剤を用いてタイヤ内表面に吸音材を貼り付けた。比較例２では、加硫前にタイヤ内面にセロファンフィルムを貼り付けておき、加硫後に該セロファンフィルムを剥がし、その位置にゴム系接着剤を用いて吸音材を貼り付けた。   In the conventional example, an attempt was made to attach the sound absorbing material to the inner surface of the tire while the release agent during vulcanization was adhered, but as a result, the sound absorbing material did not adhere. In Comparative Example 1, the release agent on the tire inner surface was washed with water, and then a sound absorbing material was attached to the tire inner surface using a rubber adhesive. In Comparative Example 2, a cellophane film was affixed to the tire inner surface before vulcanization, the cellophane film was peeled off after vulcanization, and a sound absorbing material was affixed at that position using a rubber adhesive.

実施例１では、タイヤ内表面から離型剤を取り除くことなくタイヤの内側に表１に示す配合を有する天然ゴムのラテックスを流し込み、そのタイヤを回転させながらラテックスを乾燥させることにより、タイヤ内表面に厚さ１．０ｍｍの皮膜を形成し、これを２４時間乾燥させた後、その乾燥皮膜に吸音材を貼り付けた。実施例２では、タイヤ内表面から離型剤を取り除くことなくタイヤの内側に表１に示す配合を有する天然ゴムのラテックスを流し込み、そのタイヤを回転させながらラテックスを乾燥させることにより、タイヤ内表面に厚さ１．０ｍｍの皮膜を形成し、皮膜が完成してから２時間以内に、同ラテックスが塗布された吸音材を皮膜に貼り付け、これを２４時間乾燥させた。   In Example 1, a latex of natural rubber having the composition shown in Table 1 was poured inside the tire without removing the release agent from the inner surface of the tire, and the latex was dried while rotating the tire. A film with a thickness of 1.0 mm was formed on the film, dried for 24 hours, and then a sound absorbing material was attached to the dried film. In Example 2, the inner surface of the tire is dried by pouring a latex of natural rubber having the composition shown in Table 1 into the tire without removing the release agent from the inner surface of the tire, and drying the latex while rotating the tire. A film having a thickness of 1.0 mm was formed on the film, and within 2 hours after the film was completed, the sound absorbing material coated with the latex was attached to the film and dried for 24 hours.

これら比較例１〜２及び実施例１〜２のタイヤについて、耐久試験を実施し、その耐久性を評価した。即ち、ドラム径１７０７ｍｍの室内ドラム試験機を使用し、ＪＡＴＭＡ高速耐久性試験の空気圧、荷重、速度条件で耐久性試験を実施し、１００ｋｍ走行毎に吸音材の接着面を確認し、吸音材に剥がれが生じた距離を計測した。評価結果は、比較例１の測定値を１００とする指数にて示した。この指数値が大きいほど耐久性が優れていることを意味する。その結果を表２に示す。
The tires of Comparative Examples 1 and 2 and Examples 1 and 2 were subjected to a durability test and evaluated for durability. In other words, using an indoor drum testing machine with a drum diameter of 1707 mm, a durability test was conducted under the air pressure, load, and speed conditions of the JATMA high-speed durability test, and the adhesive surface of the sound absorbing material was confirmed every 100 km traveled. The distance at which peeling occurred was measured. The evaluation results are shown as an index with the measured value of Comparative Example 1 as 100. The larger the index value, the better the durability. The results are shown in Table 2.

Figure 2005271695
Figure 2005271695

表２から判るように、実施例１〜２のタイヤは、比較例１〜２に比べて吸音材に関する耐久性が優れていた。ラテックスの乾燥皮膜の形成工程は、所定の乾燥時間を要するものの作業自体は極めて簡単である。そのため、実施例１〜２はタイヤの生産性の点でも比較例１〜２に比べて優れている。   As can be seen from Table 2, the tires of Examples 1 and 2 were superior in durability regarding the sound absorbing material as compared with Comparative Examples 1 and 2. The process of forming the latex dry film requires a predetermined drying time, but the operation itself is very simple. Therefore, Examples 1 and 2 are superior to Comparative Examples 1 and 2 in terms of tire productivity.
