Title: Sponge rubber composition
Inventor: TOGAMI HIROSHI
IPC: C08J9/10
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To obtain a sponge rubber composition which unites reduction of counterforces and prevention of the evolution of breaks and wrinkles. SOLUTION: A sponge rubber material is obtained by blending and kneading 100 pts.wt. of EPDM having a Mooney viscosity of 140-200, 70-150 pts.wt. of a paraffin oil, 50-130 pts.wt. of a SRF carbon black having a particle size of 50-90 nm and an oil absorption of 80-160 ml/100 g, and 1-15 pts.wt. of a blowing agent of OBSH. Then, the sponge rubber material is extrusion-molded and vulcanized. The blending ratio by weight of the paraffin oil to the SRF carbon black is 1.1-1.5. In order to secure the kneading processability, however, the amount of the paraffin oil directly added is at most the same as that of the SRF carbon black, and the rest of the paraffin oil is extended in the polymer in advance. Further, the base hardness in the sponge rubber is 35-50 deg. by JIS-A standard.
