The present invention relates to a rubber composition for coating a base fabric used in air packs.
〈従来の技術〉
エアパックに求められる要求性能として、難燃性、耐候

動車装備部品であることから、環境温度も低温から高温
まで巾広く、耐用年数も１０〜１５年以上を要求され、
求められる性能は厳しいものである。<Prior Art> Required performances for air packs include flame retardancy, weather resistance, heat resistance, non-air permeability, and flexibility. As it is an automotive equipment component, the environmental temperature ranges from low to high, and the service life is required to be 10 to 15 years or more.
The required performance is strict.
以上の要求に対し、従来はナイロン繊維よりなる基布に
、りＯロプレンゴムを主成分とした組成物をコーティン
グしていた。In response to the above requirements, conventionally a base fabric made of nylon fibers has been coated with a composition containing polypropylene rubber as a main component.
ナイロン繊維を基布として用いることは、所望の仕様が
広く商業的に入手が可能であり、イソシアネート化合物
を界在させてのゴム相との接着が良いことからであり、
又、クロロブレンゴムは、ハロゲン化エラストマーであ
るため難燃性であって、耐候性、耐熱性などのトータル
バランスがとれており、極性ポリマーであることから繊
維との接着性能が高いことから採用されている。Nylon fibers are used as the base fabric because they are widely available commercially with the desired specifications and have good adhesion to the rubber phase with isocyanate compounds interposed therein.
In addition, chloroprene rubber is a halogenated elastomer, so it is flame retardant, and has a good balance of weather resistance and heat resistance, and because it is a polar polymer, it has high adhesion performance with fibers, so it was chosen. has been done.
〈課題〉
しかしながら、クロロブレンゴムは主として熱的要因に
よって経時変化で脱塩酸を起こす。この脱塩酸が基布の
劣化要因となる。特に、ナイロン基布の場合、その塩酸
がナイロン分子中のアミド結合の解離の原因となり、強
度の低下を惹起していた。<Problems> However, chloroprene rubber undergoes dehydrochlorination over time, mainly due to thermal factors. This dehydrochloric acid causes deterioration of the base fabric. In particular, in the case of nylon base fabrics, the hydrochloric acid causes dissociation of amide bonds in nylon molecules, causing a decrease in strength.
そこでこのクロロブレンゴムに代えて、耐熱性。Therefore, instead of this chloroprene rubber, we used a heat-resistant one.
耐候性にすぐれ、脱塩酸のほとんど生じないポリメチレ
ンタイプのエラストマーを主成分として用いることが考
慮されるが、この場合には、基布との接着力が弱く、又
可撓性に欠け、エアパック性能を満足できない。It is considered to use a polymethylene type elastomer as the main component, which has excellent weather resistance and hardly causes dehydrochloric acid. I am not satisfied with the pack performance.
本発明はこのような事情に鑑みて、基布に対する劣化要
因を低く抑える、すなわち脱塩酸は生じるけれども経時
的に遅くなるようにし、更に基布との接着力をより向上
させるものである。In view of these circumstances, the present invention aims to suppress the deterioration factors for the base fabric, that is, dehydrochlorination occurs but slows down over time, and further improves the adhesive strength with the base fabric.
く課題を解決するための手段〉
本発明は上記課題を解決するために、クロロブレンゴム

ール樹脂との一方又は双方を配合することである。Means for Solving the Problems> In order to solve the above problems, the present invention comprises blending an elastomer having a polymethylene type saturated main chain and a hydrotalcite compound into chloroprene rubber, and further comprising: One or both of the triazine compound and the terpene-modified phenol resin are blended.
〈作用〉 クロロブレンゴムによって耐候性、耐熱老化性。<Effect> Weather resistant and heat aging resistant by chloroprene rubber.
難燃性、高接着性を発揮し、ポリメチレン型の飽和主鎖
を有するエラストマーは基布に対する劣化要因が橿めて
少なく、ハイドロタルサイト系化合物で、クロロブレン
ゴムによる脱塩酸を高能率で捕捉すると共にトリアジン
系化合物はコーティング組成物の接着活性を向上させ、
テルペン変性フェノール樹脂は基布との接着力をより強
固にするものである。The elastomer, which exhibits flame retardancy and high adhesion, and has a polymethylene-type saturated main chain, causes far less deterioration of the base fabric, and the hydrotalcite-based compound highly efficiently captures dehydrochloric acid caused by chloroprene rubber. At the same time, the triazine compound improves the adhesive activity of the coating composition,
The terpene-modified phenol resin strengthens the adhesive force with the base fabric.

It has characteristics such as high adhesion and adhesive strength, and uses this chloroprene rubber as its main ingredient, along with commonly used anti-aging agents, vulcanizing agents, vulcanization accelerators, and other additives. It is a blend of methylene type elastomer and a hydrotalcite compound.

出来、極めて好ましいものである。In the present invention, although any type of chloroprene rubber can be used, in particular, the composition ratio of 1.4 trans bonds is 85% as the composition ratio of seven-mer units.
By using a structure in which the composition ratio of 1.2 vinyl bonds is 1.2% or less, flexibility can be imparted to the composition, and the dehydrochlorination opening of chloroprene rubber can be reduced, which is extremely This is preferable.
