超声波在SBS/粘土纳米复合材料研究中的应用

采用超声波技术对粘土进行精制和有机改性，探讨超声波功率和处理时间对苯乙烯-丁二烯-苯乙烯三嵌段共聚物(SBS)/粘土纳米复合材料性能的影响。结果表明，超声波技术是粘土剥片和解团聚的有效方法，在超声波输出功率为750 W、处理时间为30 min、粘土用量为2.5份条件下，制得的复合材料拉伸强度明显提高，有机粘土在SBS基体中达到纳米级分散。;The clay was refined and organically modified with the ultrasonic technology；and the effect of the ultrasonic power and treatment time on the properties of styrene-butadiene-styrene copolymer(SBS)/clay nano-composite was investigated.The results showed that the ultrasonic was effective for clay peeling and deagglomeration；and the organic clay was dispersed in nano size in SBS matrix and the tensile strength of the composite improved significantly by using 750 W output power of ultrasonic，30 min treatment time and 2.5 phr clay
