【摘要】 探讨了CaCO3纳米粉填充环氧树脂的均匀分散技术。采用超声波振动和对CaCO3纳米粉进行硅烷偶联处理两种方法,改进CaCO3在环氧树脂中的分散效果。扫描电镜观察表明,以上两种方法比普通搅拌混合效果显著,实现了CaCO3纳米粉在环氧树脂中的均匀分散。更多还原

【Abstract】 The uniform distribution of nano CaCO3 packed in epoxy resin is studied.Ultrasonic wave and treatment of silicone coupling are used to improve the uniform distribution of nanoCaCO3 packed in epoxy resin. By means of SEM, ultrasonic wave and treatment of silicone coupling are proved to promote the uniform distribution of nanoCaCO3 packed in epoxy resin effectively, which are ideal mixing methods for nanoCaCO3 in epoxy resin and better than mechanical mixing. 更多还原
