  The invention relates to a method of curing an unsaturated rubber which is a conjugated diene homopolymer or a copolymer containing at least 50% by weight of a conjugated diene. The method involves the heating of the rubber in admixture with an adduct of nitrosophenol and methylene bis(4-phenylisocyanate) of the formula to form urethane cross-links, a scorch delay cure catalyst being added to the rubber prior to curing and the catalyst being a derivative of dithiophosphoric acid of the formula wherein R, and R2 are alkyl groups having at least 12 carbon atoms or are connected together and form an alkylene group having at least 2 carbon atoms, and R3 is hydrogen or phenethyl. Use of the invention is found to improve scorch times of natural and synthetic rubber compositions in urethane cross-linking systems.

  本发明涉及一种不饱和橡胶的硫化方法，该橡胶为共轭二烯均聚物或共聚物，其中共轭二烯的重量含量至少为 50%。该方法是将橡胶与亚硝基苯酚和亚甲基双（4-苯基异氰酸酯）的加合物混合加热，以形成氨基甲酸乙酯交联剂。 形成聚氨酯交联，在固化前向橡胶中添加焦烧延迟固化催化剂，催化剂为式 2 的二硫代磷酸衍生物 其中 R 和 R2 是至少有 12 个碳原子的烷基或连接在一起形成至少有 2 个碳原子的亚 烷基，R3 是氢或苯乙基。使用本发明可改善聚氨酯交联体系中天然橡胶和合成橡胶组合物的焦烧时间。
