摘要
通过采用硬脂酸对氢氧化镁进行表面改性的试验,阐述了硬脂酸的用量、时间、温度等各种因素对氢氧化镁改性的影响。活化指数测定结果表明改性后的氢氧化镁由亲水疏油性变成了亲油疏水性;红外光谱表明硬脂酸与氢氧化镁之间形成了化学键。
The surface of magnesium hydroxide is modified with stearic acide,and this paper elaborates the influence of factors such as quantities of stearic acide,time,temperature. It is showed from active exponent analysis that surface energy and polarity of the modified magnesium hydroxide are decreased;and IR analysis shows that the stearic acide is attached to magnesium hydroxide by chemical bond.
