Abstract

PURPOSE: The title rubber composition capable of giving vulcanizates having improved properties at a high vulcanization rate, comprising rubber, sulfur, and an acid or neutral vulcanization accelerator containing an alkali soap and zinc white.
CONSTITUTION: A composition prepared by kneading (A) 100 parts by wt. of natural rubber, general-purpose synthetic rubber, or their mixture with (B) 0.1W10 parts by wt. of sulfur, and (C) 0.1W2 parts by wt. of an acid vulcanization accelerator, e.g. mercapto-benzothiazole or tetramethyl-thiuram disulfide, or a neutral one, e.g. N-cyclohexyl- or diethylbenzthiazylsulfenamide, (D) 0.5W5 parts by wt. of an alkali soap, e.g. an alkali salt of fatty acid, e.g. oleic, stearic, or lauric acid, and (E) 0.2W15 parts by wt. of zinc white, thoroughly.
