生物过滤型汽车内饰材料的制备工艺与性能研究

Study on the Preparation Technology and Properties of Bio-Filtration Automotive Interior Materials

以聚氨酯泡沫结构的顶棚为基材,采用3种工艺将活性炭引入复合材料结构中,并采用表面喷淋的方式将复合生物酶制剂喷淋在复合板的表面,开发低气味性低挥发性有机物(VOC)的生物过滤型汽车内饰材料。研究了材料结构的优化对复合材料气味性、VOC、力学性能和声学性能的影响,以及不同制备工艺对汽车顶棚复合材料气味性和VOC的影响。结果表明,采用撒粉工艺制备的吸附层吸附性能最佳,可将聚氨酯(PU)复合板的甲醛释放量降低82.5%,将气味性提升至6级。生物过滤型汽车内饰材料(XP-PU)具有优异的吸附稳定性,可满足日常使用。生物过滤型汽车内饰材料与传统材料在力学与声学性能方面并无明显差异。

Based on the polyurethane foam roof, activated carbon was introduced into the composite material structure by three processes, and the compound biological enzyme agent was sprayed on the surface of the composite plate by surface spraying method to develop the low odor and low volatile organic compound (VOC) bio-filtration automotive interior material. The effects of material structure optimization on the odor, VOC, mechanical and acoustic properties of composite materials were studied, and the effects of preparation processeson the odor and VOC of automobile roof compositematerials. The results showed that theadsorption layer prepared by dusting technology had the best adsorption performance,and the formaldehyde emission of PU composite board could be reduced by 82.5%, and the odor could be improved to grade 6. Bio- filter automotive interior material (XP- PU) had excellent adsorption stability, could meet the daily use. There is no significant difference in mechanical and acoustic properties between the bio-filter automotive interior materials and traditional materials.
