Abstract

The work is focused on the investigation of the influence of the amount of co-agent on cross-linking and properties of rubber compounds. The in-situ radical polymerization of zinc dimethacrylate occurs during the curing process of rubber compounds with organic peroxide. Polymerized zinc dimethacrylate tends to form different types of chemical and physical linkages within the rubber matrices. As the amount of dimethacrylate ranged from 10 to 50 phr, the conversion of zinc dimethacrylate remained low. Residual zinc dimethacrylate formed micro-dispersion in the rubber matrix. The dispersion and distribution of zinc dimethacrylate in the rubber depends on the viscosity of matrix, shear stress and polarity of the matrix. Despite low conversion of zinc dimethacrylate, the application of co-agent resulted in the increase of cross-link density and improvement of physical-mechanical properties of vulcanizates.

橡胶基质与过氧化二枯基和二甲基丙烯酸锌的交联。第一部分：代理内容的影响

摘要

这项工作的重点是研究助剂用量对橡胶混合物的交联和性能的影响。二甲基丙烯酸锌的原位自由基聚合发生在橡胶化合物与有机过氧化物的固化过程中。聚合的二甲基丙烯酸锌倾向于在橡胶基体内形成不同类型的化学和物理键。当二甲基丙烯酸酯的量为10至50phr时，二甲基丙烯酸锌的转化率保持较低。残留的二甲基丙烯酸锌在橡胶基质中形成微分散体。二甲基丙烯酸锌在橡胶中的分散和分布取决于基体的粘度，剪切应力和基体的极性。尽管二甲基丙烯酸锌的转化率很低，
