RUBBER COMPOSITION CONTAINING NATURAL RUBBER, VISCOSITY STABILIZING AND ODOR INHIBITION METHOD OF NATURAL RUBBER

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition containing natural rubber achieving viscosity stabilizing over long time and having extremely reduced odor to overcome natural rubber's increase of viscosity (gelling), i.e. a phenomenon so called storage hardening for lapse period about 1 month by storage, shipping or the like even with having low viscosity just after manufacturing and also problem of unique odor by corruption or the like during storage or manufacturing process because a raw material of the natural rubber is a natural product.SOLUTION: The above problem is solved by compounding an aminoguanidine compound to natural rubber as a viscosity stabilizer and an odor inhibitor.
