て大幅に簡略化されることが期待される。(Prior Art vfI) As a general method of increasing the strength of rubber, a method of embedding various reinforcing materials into rubber is known. However, these methods require a very complicated process, since the reinforcing material in the form of long fibers is first woven into a tube or knitted, and then rubber is lined thereon. So short fI! It is possible to strengthen rubber products by dispersing fibers into rubber.
If so, the manufacturing process for the composition would involve mixing rubber, additives, and reinforcing short fibers, and then extruding or injection molding the mixture, which is significantly more efficient than the method using woven or knitted fabrics made of long fibers. It is expected that this will be simplified.

The present inventors have discovered that a reinforcing rubber composition with excellent tensile strength can be obtained by using this method, and have thus arrived at the present invention.

硫するために耐熱性の高いアクリルＮ１雑が望ましい。The acrylic fibers used in the present invention are not particularly limited, but acrylic N1 miscellaneous fibers with high heat resistance are desirable because they are vulcanized at high temperatures when molding the acrylic fiber-reinforced rubber composition.

０の範囲が好！しい。Therefore, the acrylic N1. The polymer FA constituting the fiber preferably has 90 or more acrylonitrile units. In order to effectively reinforce the rubber, it is preferable to use high-strength acrylic m-fiber.
It is preferable to use acrylonitrile fibers having a tensile strength of 52/d or more, preferably 101 F/d or more, and more preferably 159/d or more. Furthermore, regarding the form of the acrylic fibers, the length of the short fibers is 01 to 10, the fineness of the short fibers is 1l11d to 10d1, and the aspect ratio is 10 to 100.
I like the range of 0! Yes.

得られｉｌＡ。When the short fiber length is less than α1wN, effective reinforcement of the rubber composition becomes a solid solution, and when the length exceeds 10mm, acrylic N11. The dispersibility of the fibers decreases, and the fineness of short fibers with a diameter of 1 mm (b0) decreases (11 (less than 1, the acrylic fiber I
The dispersibility of the acrylic fibers decreases, and on the other hand, if it exceeds 10+1, the effective surface area of the acrylic fibers decreases relatively, and a sufficient reinforcing effect is obtained.

XA is unfavorable due to its poor processability.
