MoS_2对金属基复合阻尼结构性能的影响

Influence of MoS_2 on Properties of Metal Based Composite Damping Structures

通过共混法以镀锌钢板为基材制备了含有MoS_2的金属基复合阻尼结构。分析MoS_2添加量对阻尼损耗因子、隔声性能和涂层附着力等性能的影响。结果表明:MoS_2可有效提高阻尼性能、隔声性能和附着力。当MoS_2的质量占填料总质量的18.75%时,阻尼损耗因子最优;阻尼结构的隔声性能随MoS_2含量的增加而提高;当MoS_2添加量为12.50%时,涂层附着力可达到2.0 MPa。

The galvanized steel sheet based composite damping structures with MoSz were prepared by blending method. The influences of the amount of MoS2 on the damping dissipation factor, sound insulation performance and adhesion properties were analyzed. The results show that damping properties, sound insulation performance and adhesion effectively improve when MoS2 is added. The damping dissipation factor is best when the amount of MoS2 is accounted for 18.75% of total amount of fillers. With the increase of amount of MoS2, the sound insulation performance of damping structure improves. The adhesion of the coating is 2.0MPa when the amount of MoS2 is 12.50 %.
