铝硅酸盐工业废渣表面改性工艺研究

Study on the Surface Modification Technology of Aluminosilicate Trade Waste

以铝硅酸盐工业废渣为原料 ,分别进行了表面活性剂、偶联剂单一表面改性和复合表面改性试验研究。结果表明 ,KH- 5 6 0硅烷偶联剂与硬脂酸复合改性处理效果最佳。其工艺条件为 :偶联剂用量 0 .2 %～ 0 .5 % ,硬脂酸用量 2 %～ 4 % ,改性时间 30～ 5 0 min,搅拌速度 95 0 r/

Using aluminosilicate trade waste as a raw material,the experimental research on single surface modification and compounded surface modification of surfactant and coupling agent was performed.The results obtained shown that the efficiency of KH-560 silane coupling agent and stearic acid compounded modification treatment is optimal.The process conditions are as follows:coupling agent 0.2%～0.5%,stearic acid 2%～4%,modification time 30～50min.Stirring speed 950r/min.
