摘　　要：采用微波技术制备了高黏度插层型FA367/膨润土纳米复合增黏剂,研究了制备方法、微波辐射时间和微波辐射功率对FA367/膨润土纳米复合增黏剂水溶液黏度的影响。结果其最佳微波制备条件:微波辐射时间为1min、辐射功率为195W。在此条件制备的纳米复合增黏剂黏度最大,与物理混合法制备的复合增黏剂相比,其在1min时测得的旋转黏度提高了50%。同时用XRD表征了该纳米复合增黏剂的插层结构,用TGA测试了该纳米复合增黏剂的热稳定性,结果表明,FA367/膨润土纳米插层结构的存在明显提高了FA367的耐热性能。Using the microwave technology, a high viscosity FA367/bentonite nanometer composite was developed. In laboratory research, the preparation process, time for microwave radiation, and the power of the microwave were studied on the effects of these factors on the final product. The optimal parameters for the preparation were as follows: microwave radiation time was 1 min and power of the microwave was 195 W. The nanometer composite prepared under these conditions had the highest viscosity. Compared with the composite viscosifier made with physical mixing method, the viscosifier prepared had (rotational) viscosity (measured at 1 min)) 50% higher than the former. Structure characterization of the viscosifier by using XRD and measurement of the high temperature stability of the viscosifier by using TGA were also conducted in laboratory studies. It was shown that the existence of the imbedded layer in the nanometer composite was the key for its high temperature stability.
