ニトリルゴムの圧縮歪(第2報)

Abstract

In the previous report (I), we have calculated instant-rigidity G_0, late-rigidity G_1, late shear viscosity η_1, and permanent shear viscosity η_2 which changed along to amount of sulfur, carbon, filler, etc, to that of rubber. As the result of calculation, we could reserch about the combination of rubber and other submaterials whose instant deformation was large and creep deformation was small. It was most desired condition that zinc oxide, carbon, stearic acid, sulfur were about 5, 40, 1.5, 3 Parts respectively to 100 parts of rubber. In this report, we have investigated that the amounts of accelerators of vulcanization and sulfur have influenced to compressed deformation, and late-deformation, and calculated G_0 G_1, η_2, respectively.
