以金属钠为还原剂,将正硅酸乙酯与氯代正丁烷进行缩合反应制备了二正丁基二乙氧基硅烷,优化了反应条件,经红外、核磁共振表征确证了产物分子结构,并通过性能测试证实产物应用于聚氨酯涂料具有较好的疏水效果。
Di-n-butyldiethoxysilane was prepared by condensation reaction of tetraethylorthosilicate and n-butanol with sodium metal as reductant, and the reaction conditions were optimized. The molecular structure of the product was confirmed by IR and 1H NMR , And through the performance test confirmed that the product applied to the polyurethane coating has better hydrophobic effect.
