Abstract
(EN)
Provided is a halogen-containing acrylic rubber composition which contains a vulcanizing system that includes both a vulcanizing agent comprising thiocyanuric acid and a vulcanization accelerator, said vulcanization accelerator being a vulcanization accelerator which generates no carcinogenic nitrosamines. Further, the halogen-containing acrylic rubber composition exhibits excellent scorch resistance and a high vulcanization rate, and can provide products of vulcanization which exhibit reduced compression set. Specifically provided is a halogen-containing acrylic rubber composition which comprises a halogen-containing acrylic rubber, a vulcanizing agent that contains a sulfur-donating compound, and a vulcanization accelerator, wherein trithiocyanuric acid is used as the vulcanizing agent, and calcium hydroxide is used as the vulcanization accelerator, with the contents of trithiocyanuric acid and calcium hydroxide being 0.1 to 3.0 parts by weight and 0.1 to 9 parts by weight respectively per 100 parts by weight of the halogen-containing acrylic rubber.

L'invention porte sur une composition de caoutchouc acrylique halogéné qui contient un système de vulcanisation qui comprend à la fois un agent de vulcanisation comprenant de l'acide thiocyanurique et un accélérateur de vulcanisation, ledit accélérateur de vulcanisation étant un accélérateur de vulcanisation qui ne produit pas de nitrosamines cancérogènes. En outre, la composition de caoutchouc acrylique halogéné présente une excellente résistance au grillage et une vitesse de vulcanisation élevée et permet de fournir des produits de vulcanisation qui présentent une déformation rémanente à la compression réduite. De façon spécifique l'invention porte sur une composition de caoutchouc acrylique halogéné qui comprend un caoutchouc acrylique halogéné, un agent de vulcanisation qui contient un composé donneur de soufre et un accélérateur de vulcanisation, de l'acide trithiocyanurique étant utilisé comme agent de vulcanisation et de l'hydroxyde de calcium étant utilisé comme accélérateur de vulcanisation, les teneurs de l'acide trithiocyanurique et de l'hydroxyde de sodium étant de 0,1 à 3,0 parties en poids et 0,1 à 9 parties en poids, respectivement, pour 100 parties en poids du caoutchouc acrylique halogéné.
