摘　　要：为了探索出一种具有优良吸音性能的车用衣帽架配比工艺,在聚丙烯纤维、玻璃纤维中加入少量的玄武岩纤维,使之进行不同比例的配比,控制实验的变量热轧温度、热压辊速度、热轧压力,根据四组分四因素设计正交试验L16(44),制得初步衣帽架。对衣帽架进行吸音系数、强力及顶破强力的测试分析。实验表明:配比度在聚丙烯:玻璃纤维:玄武岩纤维=45%:50%:5%,热轧温度为200℃,热压辊转速为4r/min,热轧压力为10MPa时,衣帽架吸声性能最好;当纤维的配比度PP:玻璃纤维:玄武岩纤维=40%:50%;10%时,且热轧温度温度为200摄氏度,热轧辊转速为3转/min,热轧的压力为11MPa时,所制得的针刺非织造材料经热轧后的断裂强力最高。In order to explore a kind of excellent sound-absorbing performance of vehicle coatrack matching technology, the experiment added a small amount of basalt fiber in polypropylene fibers and glass fibers, so that the ratio of different proportions was ensured. Then the variables of experiment： hot rolling temperature, hot roll speed, hot rolling pressure were under control. According to the four components of four factors, the experiment designed orthogonal test L16（4^4） and made a preliminary coatrack. By testing the coatrack＇s sound absorbing, strength and bursting strength, we got a conclusion that when the ratio of polypropylene： glass fiber, basalt fiber is 40% ： 50% ： 5%, hot rolling temperature is 200 ℃, hot pressing roller speed is 4 r/min and hot rolling pressure is 10 MPa, the coatrack has the the best sound absorption performance. When the matching degree of PP fiber： glass fiber, basalt fiber = 40% ： 50%; 10%, and hot rolling temperature is 200 degrees Celsius temperature, hot roll speed for 3 r/min, the pressure of the hot rolling of 11 MPa, the prepared needle punched nonwovens have the highest breaking strength after hot rolling.
