A deodorized rubber additive comprising
(1) a phosphorus-containing compound of formula
wherein R, and R2 each represent an alkyl, alkenyl, cycloalkyl or aryl group and X represents an oxygen or sulfur atom; or a sulfonamide compound of formula
wherein R3 and R4 each represent an alkyl group of 1 to 12 arbon atoms, a cycloalkyl group or an aryl group, and
(2) at least one material selected from fine particle iorganic fillers for rubber compounding, amine com- pounds, and metal salts of fatty acids. Vulcanisation in the presence of this deodorized rubber additive as a retarder, proceeds at a favourable rate with reduced emission of odours characteristic of the phosphorus-containing compound of formula (1) and the sulfonamide of formula (II).
一种脱臭橡胶添加剂,包括
(1) 式中的含磷化合物
式中 R 和 R2 分别代表烷基、烯基、环烷基或芳基,X 代表氧原子或硫原子;或式中的磺酰胺化合物
其中 R3 和 R4 各自代表 1 至 12 个碳原子的烷基、环烷基或芳基,和
(2) 至少一种选自橡胶混炼用细颗粒无机填料、胺化合物和脂肪酸金属盐的材料。在有这种脱臭橡胶添加剂作为缓凝剂的情况下,硫化过程的速度会更快,同时释放出的式(1)含磷化合物和式(II)磺酰胺所特有的气味也会更少。
