ーブルの保護シース材料としても広く重用されている。[Prior art] Polychlorograne rubber has been produced for nearly 60 years since it was proposed, and it has excellent toughness, oil resistance,
Because of its wear-resistant and flame-retardant properties, it is widely used as a protective sheath material for electric wires and cables, as well as for automobile parts and various types of bows.

のシース材料として古くから使用されてきた。That is, in addition to the above-mentioned excellent properties, it has excellent flexibility, so it has long been used as a sheath material for moving cables such as cabtire cables, welding cables, elevator gauges, and robot cables.

てくる。This polychloroprene rubber has double bonds in its main chain, but it is relatively durable compared to natural rubber, polyisoprene, butadiene rubber, styrene-butadiene rubber, nitrile rubber, etc., which also have double bonds in their main chain. Good ozone properties. This is thought to be due to steric hindrance of the chlorine atom in the molecule. However, if they are exposed to high concentrations of ozone while under stress, they will gradually be attacked by the ozone, causing defects such as hair cracks due to the breakage of the main chain.
［発明が解決しようとする課題］
ポリクロロプレンゴムの耐オゾン性を向上させるために
、従来より各種の耐オゾン劣化防止剤をゴム材料中に添

添加して材料表面にブルーミンクさせ、表面に保護膜を
作る手法か採られてきた。[Problems to be Solved by the Invention] In order to improve the ozone resistance of polychloroprene rubber, various ozone deterioration inhibitors have traditionally been added to rubber materials, or paraffin wax, etc. has been added in slightly larger amounts. A method has been adopted in which the material is bloomed onto the surface of the material to form a protective film on the surface.
しかしながら、耐オゾン劣化防止剤による方法はクラッ

ると耐オゾン性は急速に低下するという欠点があり耐久
性の点で問題があった。However, although the method using an anti-ozone deterioration agent can extend the crack generation time to some extent, it is not a perfect method, and has the disadvantage that cracks can easily occur if the product is used in a manner where it is subjected to large amounts of strain. . Also,
The method of adding paraffin wax or the like has a drawback in that ozone resistance rapidly decreases if the paraffin wax film protecting the surface is lost due to rubbing, etc., and there is a problem in terms of durability.

のである。The purpose of the present invention is to solve the problems of the prior art as described above, to improve the ozone resistance of Borin 1F0-prene rubber, and to provide a thermosetting material that also has mechanical strength and flame retardancy. It is intended to provide a polymer blend.

を形成させたものである。[Means for Solving the Problems 1] The present invention blends 5 to 80 parts by weight of ethylene propylene rubber (EP rubber) to 100 parts by weight of polychloroprene rubber to form an interpenetrating polymer network structure by crosslinking. This is what I did.

状等によりどちらを選んでも差支えない。Examples of EP rubber include sulfur-curable ethylene propylene gentor polymers, and diene types include ethylthenenorbornene (ENr3m).
Dicyclopentadiene (DCPD), 1,4-hexadiene (1,4HD) + methylenenorhonen (MN
I can list B+ etc. Further, as the ethylene propylene rubber (EP rubber) to be blended, EP rubbers (EPM and EPDM) containing vinylsilane compounds having the ability to be activated by the presence of water in graphs 1 to 1 are also included. Vinyl silane compounds include vinyl 1 to lith (β
Me+-ijetoxy) silane, vinyltriethoxysilane, vinyltrimethoxysilane, γ-methacryloxyglopytritrimethoxysilane, and vinyltriacetoxysilane, which are processed by radical reaction with peroxides such as dicumyl peroxide. EPM and EPD
In this case, vinyl silane needs to be grafted in an amount of 0.5 to 301 fLn parts per 100 parts by weight of EP rubber, and if it is less than 0.5 parts by weight, the crosslinking effect will be poor. Moreover, if it exceeds 30 parts by weight, processing of the grafted material becomes difficult. EP rubber is water-crosslinked after being blended, and there are two ways to use the water-crosslinking reaction catalyst: directly injecting it into the material as a masterbatch, and applying it to the surface after molding. There is no problem in selecting either method depending on the processing conditions or the shape of the molded product.
ＢＰゴムのブレンド量としては、ポリクロロプレンゴム
１００′ｆｊＬ量部に対し５〜８０重量部とするのがよ
く、５重量部より少くては耐オゾン性の向上効果がみら
れず、８０重量部を越えるようでは、難燃性などの特性
劣化がみられるようになり好ましくない。The blending amount of BP rubber is preferably 5 to 80 parts by weight per 100'fjL parts of polychloroprene rubber; if it is less than 5 parts by weight, no effect of improving ozone resistance is observed, and 80 parts by weight is used. If it exceeds this value, properties such as flame retardancy will deteriorate, which is undesirable.
なお、得られた重合体ブレンド物に加硫剤や加硫助剤の
他、老化防止剤、滑剤、操作油、充てん剤、補強剤等を
適宜添加することは差支えない。In addition, in addition to a vulcanizing agent and a vulcanization aid, an anti-aging agent, a lubricant, an operating oil, a filler, a reinforcing agent, etc. may be appropriately added to the obtained polymer blend.

EP rubber or silane. In the case of the water-crosslinked type, after pressing, apply a catalyst (e.g. dibutyltin dilaurate) on the surface, wrap it loosely with aluminum foil, and hold it in a suitable container with water at the bottom so as not to immerse it directly in water. The crosslinking reaction was carried out by standing at 80° C. for 24 hours.
