二乙基二硫代氨基甲酸稀土配合物的合成及促进橡胶硫化性能研究

于空气中一步合成出二乙基二硫代氨基甲酸稀土 (镧、钕、铕和混合稀土 )共四种配合物 ,产率达 90 %以上 ,本文首次报道了该系列稀土配合物促进橡胶硫化性能和应用于胶鞋大底生产的配方试验 ,结果表明 ,除混合稀土配合物外 ,镧、钕、铕配合物均具有对橡胶硫化促进作用。选择镧配合物在胶鞋大底生产上试用 ,生产的胶鞋物理机械性能均达国家一级品标准。

Synthesis and Vulcanizing Properties of Rare Earth Diethyldithiocarbaminate Complexes

The four rare earth (La,Nd,Eu and Mixing RE) diethyldithiocarbaminate solid complexes have been synthesized through one step in air.The yield of the compounds is over 90%.The vulcanizing properties of these complexes have been studied.The result indicates that all complexes(except for mixing RE complex)have vulcanizing acceleration role.The performance of the rubber shoes produced by La complex can reach national standard.
