Accelerator composition for a rubber latex derived from a conjugated diene and optionally a vinyl aromatic comonomer comprising: (i) a diïsopropyl xanthogen polysulphide (DIXP), (ii) an alkyldithiocarbamate wherein the alkyl chain contains from 5 to 20 carbon atoms , and (iii) diphenylguanidine (DPG), a curable aqueous synthetic rubber latex composition comprising said accelerator composition, a process for the water-based solvent-free manufacture of synthetic shaped synthetic elastomeric articles, prepared by using said accelerator composition.
L'invention concerne une composition accélératrice d'un latex d'élastomère-caoutchouc, dérivée d'un diène conjugué et éventuellement d'un comonomère vinylaromatique comprenant : (i) un diïsopropyl xanthogène polysulfure (DIXP), (ii) un alkyldithiocarbamate dans lequel la chaîne alkyle contient entre 5 et 20 atomes de carbone, et (iii) de la diphénylguanidine (DPG). L'invention concerne également une composition de latex d'élastomère-caoutchouc synthétique, aqueuse, durcissable, comprenant ladite composition accélératrice, un procédé de production sans solvant, à base d'eau, d'articles élastomères synthétiques façonnés, préparés à l'aide de ladite composition accélératrice.
