この発明は繊維補強層を有するゴムホースの改良、特に
繊維補強層とゴム層との接着性の改良に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in rubber hoses having fiber-reinforced layers, and particularly to improvements in the adhesion between the fiber-reinforced layers and the rubber layers.
一般にポリアミド繊維（ナイロン）、ＰＶＰ繊維（ビニ
ロン）などの合成繊維からなる補強材と、クロロプレン
（ＣＲ）との組合わせから成るホースが多量に使用され
ているが、このような構成から成るゴムホースでは実用
時外層に亀裂が発生し、これがホース破裂の原因となる
恐れがあることから耐亀裂性のゴム材料が望まれている
。Generally, hoses made of a combination of reinforcing materials made of synthetic fibers such as polyamide fibers (nylon) and PVP fibers (vinylon) and chloroprene (CR) are used in large quantities, but rubber hoses made of such a structure A crack-resistant rubber material is desired because cracks may occur in the outer layer during practical use, which may cause the hose to burst.
種々検討の結果、ＣＲにエチレン−プロピレンゴム特に
エチレン−プロピレン−ジエン三元共重合体（ＥＰＤＭ
）をブレンドしたものは現用のＣＲ単独よりも耐亀裂性
が格段にすぐれていることを見出した。As a result of various studies, we found that ethylene-propylene rubber, especially ethylene-propylene-diene terpolymer (EPDM)
) was found to have much better crack resistance than the currently used CR alone.
この構成によれば、ＥＰＤＭの作用効果により当該ゴム
層はオゾン老化防止剤に頼らなくても長時間のオゾン寿
命を保持することができるだけでなく、ホースの使用温
度範囲が拡大され、耐鉱物油性が得られる等の効果もあ
る。According to this configuration, due to the effects of EPDM, the rubber layer can not only maintain a long ozone life without relying on ozone anti-aging agents, but also expand the operating temperature range of the hose and have mineral oil resistance. There are also effects such as obtaining.
しかしながらＥＰＤＭをブレンドしたゴムは繊維との接
着性が悪くなり、汎用されているレゾルシン−ホルマリ
ン−ゴムラテックス接着剤（ＲＦＬ）を用いても十分な
接着が得られない欠点がある。However, rubber blended with EPDM has poor adhesion to fibers, and has the drawback that sufficient adhesion cannot be obtained even with the commonly used resorcinol-formalin-rubber latex adhesive (RFL).
ＥＰＤＭと繊維との良好な接着剤としては、ハロゲン化

リマーの混合物を主成分とする溶剤型接着剤があるが、
このような溶剤型接着剤は火災や人体への影響などの点
からみれば、水分散型のＲＦＬ接着剤よりも公害性が増
す欠点があり、また既存のＲＦＬ処理設備も使用できな
い等から、工業的にはまだ納得のいくものではない。Good adhesives for EPDM and fibers include solvent-based adhesives based on halogenated EPDM or mixtures of blocked isocyanates and certain polymers.
Such solvent-based adhesives have the disadvantage of being more polluting than water-dispersed RFL adhesives in terms of fire hazards and the effects on the human body, and they also cannot be used with existing RFL processing equipment. Industrially, this is not yet satisfactory.

有するゴムホースにある。The gist of the present invention is that chloroprene rubber has 90%

．． A rubber hose having a fiber reinforced layer characterized in that the inner layer and the outer layer are made of a rubber material containing 2 to 10 parts by weight.
以下、この発明を説明すると、第１表は各種ゴム配合例
を示している。To explain this invention below, Table 1 shows various rubber compounding examples.
第１表の配合割合による混練組成ゴム材料を、ゴムホー

た。The kneaded composition rubber materials having the compounding ratios shown in Table 1 were used as the inner layer, the fiber reinforced layer, and the outer layer of the outer layer constituting the rubber hose, and rubber samples were obtained by press vulcanization.
この場合、外層下に形成される補強層としてはＲＦＬで

A braided reinforcing layer consisting of 200 denier/700 filament x 3 pieces x 24 strokes was used.

A rubber-based solvent-based adhesive containing chlorofluorocarbon (fluorocarbon) *quisocyanate was also applied onto the treated braided reinforcing layer.
第２表はそれら各試料の特性比較である。Table 2 shows a comparison of the characteristics of each sample.

も接着力が向上し、実用上十分な接着力（約２ ｋｇ／

と比べて遜色ないものが得られることが判る。As shown in the results, conventional general-purpose RFL treatment alone results in almost no adhesion, but the adhesive strength of the present invention is improved, and the adhesive strength is practically sufficient (approximately 2 kg/
crn), and it can be seen that a product comparable to that obtained by adding a layering agent on the reinforcing layer can be obtained.
また、反応促進剤の効果は補強層のＲＦＬ処理の有無に
かかわらず認められるが、ＲＦＬで処理した場合には増

尚、ＥＰＤＭとＣＲはＥＰＤＭ／ＣＲ＝３０／７０の場
合を示したが、相互の特性上からすればＥＰＤＭ／ＣＲ
＝５ｏ〜１０／９０〜５０の配合範囲が望ましい。Note that EPDM and CR are shown in the case of EPDM/CR = 30/70, but considering their characteristics, EPDM/CR
A blending range of =5o to 10/90 to 50 is desirable.

めである。In the present invention, the amount of one or more reaction accelerators selected from the condensate of resorcinol and formaldehyde, resorcinol, and hexamethylenetetramine is reduced to zero.
．． The reason why the amount is 2 to 10 parts by weight is that if it is less than 0.2 parts by weight, no effect of improving adhesion can be obtained, and if it is more than 10 parts by weight, a remarkable effect of improving adhesion cannot be obtained in proportion to the amount added. It is.

ものを得ることができる。As described above, according to the present invention, the rubber layer is composed of a rubber material in which a reaction accelerator mainly containing resorcinol is blended with a mixture mainly composed of a blend of EPDM and CR. The adhesive force with the adjacent fiber reinforced layer is extremely strong, and it is possible to obtain an adhesive force comparable to that obtained when an adhesive is added.
