摘要
应用２—乙烯基吩噻嗪作为二烯类橡胶的防老剂和目前所应用的防老剂相比较，它能使异戊二烯橡胶可塑度增高，使硫化橡胶的防热老化及防臭氧老化性增强，同时，该防老剂在橡胶制品表面喷霜较少，在混炼胶中使用量更高，而不会引起分层现象，是一种很好的新型防老剂，应加以推广应用。
In this article consideration has been given to the principle and regularitiesof using 2－viny 1－phenotiazine as an anti－aging component in rubber mixture based ondienes rubbers．The research is about rubber mixtures based on rubbers SKI－3，SKS－30，ARKP，SKD and fillers P5 14，P234．Neozone－D，quinol－ED，pheno－tiazine and 2－viny 1－phenotiazine were used as anti－aging components．It has demon-strated that rubber mixtures based on SKI-3 with 2－viny1-phenotiazine have higher plas-ticity when compared with the well－known anti－ageing components：phenotiazine andquinol－ED，The use of 2－viny l－phenotia－zine shows that the rubber mixtures providevulcanizates with high stability against ozone influence and repeated defonnation。Thisanti－aging component sweats less on the rubber surface, so that it makes it possible to dorubber mixtures a greater quantity of the component without causing any anxiety aboutIink strength of separate parts of composition。Therefore，2-vinyl- phenotiazine can berecommended as an effective substitute for the existing anti-aging components
