摘要:塑料零件在受到挤压摩擦时,容易发生粘滑现象,从而产生异响,目前汽车行业普遍采用的涂抹润滑油、消音水、粘贴无纺布类毛毡等措施增加了产品的生产周期与成本。针对上述情况,并基于吉利汽车标准,通过添加热塑性聚酯弹性体(TPEE)与聚碳酸酯/丙烯腈-丁二烯-苯乙烯塑料(PC/ABS)共混改性,研发出了一款具有优异降噪功能的PC/ABS材料,对比了降噪PC/ABS与普通PC/ABS的常规性能和降噪性能。结果表明,与普通PC/ABS相比,降噪PC/ABS的力学性能略有降低但保持了良好的耐刮擦性能、耐化学药品性以及耐光老化性能,而且具有更低的响度、更小的振动加速度以及更低的异响风险系数值,最终成功应用在多个车型的仪表板部件上,实现国产降噪材料的成功量产。  
Abstract:The plastic parts which are subjected to squeeze and friction are prone to stick-slip, resulting into the abnormal noise. At present, measures such as applying lubricating oil, silencer water, and sticking non-woven felts commonly used in the automotive industry increase undoubtedly the production cycle and cost. In response to the above situation, and based on Geely automobile standards, a polycarbonate (PC)/acrylonitrile-butadiene-styrene plastic (ABS) with the function of excellent noise reduction was prepared by blending the thermoplastic polyester elastomer (TPEE) with PC/ABS, the conventional performances and noise reduction performances of the noise reduction PC/ABS and ordinary PC/ABS were compared. The results show that, compared with ordinary PC/ABS, the mechanical properties of the noise reduction PC/ABS decrease slightly, but good scratch resistance, chemical resistance and light aging resistance are kept, moreover, the noise reduction PC/ABS possesses lower loudness, smaller vibration acceleration and lower abnormal noise risk priority number value, which is applied to the instrument panels of many automotive models, and realizes the successful mass production of domestic noise reduction materials.
