まず、本発明の凝固剤について以下に説明する。
本発明の凝固剤(本発明の第1の態様の凝固剤)は、
植物性タンパク質、ペクチン、セルロース、リン脂質及び脂肪酸グリセライドからなる群から選ばれる少なくとも1種の成分を含有し、
タイヤパンク修理液100質量部に対する前記成分の量が16質量部以上である、タイヤパンク修理液の凝固剤である。
植物性タンパク質、ペクチン、セルロース及び脂肪酸グリセライドを含有し、
前記植物性タンパク質:前記ペクチン:前記セルロース:前記脂肪酸グリセライドの質量比が10-25:30-50:25-35:5-15であり、
タイヤパンク修理液100質量部に対する、前記植物性タンパク質、前記ペクチン、前記セルロース及び前記脂肪酸グリセライドの合計量が8質量部以上である、タイヤパンク修理液の凝固剤である。
本願発明者は、植物性タンパク質、ペクチン、セルロース、リン脂質及び脂肪酸グリセライドからなる群から選ばれる少なくとも1種の成分が、タイヤパンク修理液に含まれる、エマルジョン(ラテックスを含む。)の分散質であるゴム粒子及び/又は樹脂粒子を融着させ、あるいは、タイヤパンク修理液に含まれる、水及び/又は凍結防止剤を吸収することによって、タイヤパンク修理液が凝固することを見出した。
本願発明者は、植物性タンパク質、ペクチンは、上記のゴム粒子及び/又は樹脂粒子を凝固させるように働き、セルロースはタイヤパンク修理液の粘度を上昇させるように働き、脂肪酸グリセライドは凍結防止剤に溶解してタイヤパンク修理液を増粘させると推測する。
さらに本発明の凝固剤が更に金属塩を含有する場合、金属塩が上記のゴム粒子及び/又は樹脂粒子をお互いに凝集させ、タイヤパンク修理液から析出させる作用があることを見出した。
なお、上記メカニズムは本願発明者の推測であり、メカニズムが上記以外であっても本発明の範囲内である。
植物性タンパク質、ペクチン、セルロース、リン脂質及び脂肪酸グリセライドからなる群から選ばれる少なくとも1種の成分を含有し、
タイヤパンク修理液100質量部に対する前記成分の量が16質量部以上である、タイヤパンク修理液の凝固剤である。
セルロースとしては、例えば、セルロース、結晶セルロース;メチルセルロース、エチルセルロース、メチルヒドロキシプロピルセルロース、ヒドロキシエチルセルロース、セルロース硫酸ナトリウム、ヒドロキシプロピルセルロース、カルボキシメチルセルロース、カルボキシメチルセルロースナトリウムのようなセルロース誘導体が挙げられる。なかでも、凝固性能により優れ、安価である点において優れるという観点から、セルロースが好ましい。
なかでも、凝固性能により優れ、安価で入手しやすい点に優れるという観点から、脂肪酸トリグリセライドが好ましく、オレイン酸、リノール酸、リノレン酸のいずれか1種若しくは2種以上により形成されるトリグリセライドがより好ましい。
脂肪酸グリセライドとして、例えば、ヒマシ油、大豆油、ヒマワリ油を使用することができる。ヒマシ油は、脂肪酸として例えば、パルミチン酸、ステアリン酸、オレイン酸、リノール酸、リノレン酸、リシノレイン酸、ジヒドロキシ酸を有することができる。
植物性タンパク質はそれぞれ単独でまたは2種以上を組み合わせて使用することができる。ペクチン、セルロース、リン脂質及び脂肪酸グリセライドについても同様である。
例えば、植物性タンパク質とペクチンとの組合わせの場合、凝固性能により優れるという観点から、植物性タンパク質:ペクチンの質量比は1:0.8~1:8であるのが好ましい。
植物性タンパク質とセルロースとの組合わせの場合、凝固性能により優れ、安価であるという観点から、植物性タンパク質:セルロースの質量比は、1:0.5~1:4であるのが好ましく、1:0.5~1:2であるのが好ましい。
セルロースと脂肪酸グリセライドとの組合わせの場合、凝固性能により優れ、安価であるという観点から、セルロース:脂肪酸グリセライドの質量比は、1:0.1~1:2であるのが好ましく、1:0.1~1:1であるのがより好ましい。
例えば、植物性タンパク質とペクチンとセルロースとの組合わせの場合、凝固性能により優れるという観点から、植物性タンパク質:ペクチン:セルロースの質量比が、1~2.5:1~5.5:0.8~5であるのが好ましい。
植物性タンパク質とセルロースと脂肪酸グリセライドとの組合わせの場合、凝固性能により優れるという観点から、植物性タンパク質:セルロース:脂肪酸グリセライドの質量比が、0.7~3:2~4:0.25~1.5であるのが好ましい。
ペクチンとセルロースと脂肪酸グリセライドとの組合わせの場合、凝固性能により優れるという観点から、ペクチン:セルロース:脂肪酸グリセライドの質量比が、0.7~6:0.5~4:0.5~2であるのが好ましい。
具体的には例えば、植物性タンパク質:ペクチン:セルロース:脂肪酸グリセライドの質量比が、
5~9:20~60:15~50:5~20、26~35:20~60:15~50:5~20、
5~35:51~60:15~50:5~20、5~35:20~29:15~50:5~20、
5~35:20~60:15~24:5~20、5~35:20~60:36~50:5~20、
5~35:20~60:15~50:16~20であるとすることができる。
本発明の第1の態様の凝固剤が上記成分のみからなる場合、成分の量は、凝固性能により優れるという観点から、タイヤパンク修理液100質量部に対して、16~100質量部であるのが好ましく、20~40質量部であるのがより好ましい。
本発明の第2の態様の凝固剤は、
植物性タンパク質、ペクチン、セルロース及び脂肪酸グリセライドを含有し、
前記植物性タンパク質:前記ペクチン:前記セルロース:前記脂肪酸グリセライドの質量比が10-25:30-50:25-35:5-15であり、
タイヤパンク修理液100質量部に対する、前記植物性タンパク質、前記ペクチン、前記セルロース及び前記脂肪酸グリセライドの合計量が8質量部以上である、タイヤパンク修理液の凝固剤である。
本発明の第2の態様の凝固剤に使用される、植物性タンパク質、ペクチン、セルロース及び脂肪酸グリセライドは、本発明の第1の態様の凝固剤に使用される、植物性タンパク質、ペクチン、セルロース及び脂肪酸グリセライドと同様である。
本発明の第2の態様の凝固剤が上記成分のみからなる場合、上記4成分の合計量は、凝固性能により優れるという観点から、タイヤパンク修理液100質量部に対して、8~100質量部であるのが好ましく、10~50質量部であるのがより好ましい。
本発明の凝固剤(第1の態様又は第2の態様)はその形態について特に制限されない。例えば、本発明の凝固剤を一括梱包した態様とすることができる。一括梱包としては、例えば、全ての成分が1つのパッケージに入っている1パッケージタイプ;成分が2つ以上のパッケージに別々に入れられており、2つ以上のパッケージが1つのセットとなっているセット型タイプが挙げられる。
セット型タイプで添加剤を使用する場合は、添加剤をいずれのパッケージに添加してもよい。
本発明のタイヤパンク修理キットは、タイヤパンク修理液と本発明の凝固剤とを有する、タイヤパンク修理キットである。
タイヤパンク修理液に含有されるエマルジョンとしては、例えば、天然ゴム系ラテックス、合成ゴム系ラテックス、合成樹脂系エマルジョンが挙げられる。
タイヤパンク修理液に用いられる天然ゴム系ラテックスは特に制限されない。
合成ゴム系ラテックスは特に制限されず、例えば、従来公知のものが挙げられる。具体的には例えば、スチレン-ブタジエンゴム(SBR)、アクリロニトリル-ブタジエンゴム(NBR)、クロロプレンゴム(CR)のような合成ゴムのラテックスが挙げられる。
エマルジョンはその製造について特に制限されない。例えば、従来公知のものが挙げられる。エマルジョンは、単独で用いてもよく、2種以上を併用してもよい。
中でも、入手が容易で安価であるという観点から、エチレン酢酸ビニル系エマルジョン、天然ゴムラテックス、SBRラテックスが好ましい。
また、粘着付与剤はこれらの樹脂を乳化して得られるエマルジョンであるのが、タイヤパンク修理液に含有されるエマルジョンとの相溶性に優れる点から好ましい態様の1つとして挙げられる。粘着付与剤は、単独で用いてもよく、2種以上を併用してもよい。
本発明のタイヤパンク修理キットはタイヤパンク応急修理キットとして使用することができる。
