采用聚丙烯酸酯乳液为基体材料，片状绢云母和碳酸钙为主要填料制得高性能车用阻尼复合涂料，测得其阻尼损耗因子和在不同频率下的隔声量。结果表示：加入不同粒径的片状云母，能在一定范围内有效地提高材料的隔声性能和阻尼性能，但却使乳液中大分子链与填料之间的表面结合相对困难。通过使用硅烷偶联剂对云母进行表面改性处理，不仅能够有效地改善大分子链与填料之间的相容性情况，同时还能明显提高材料的阻尼性能及隔声性能。

The high damping composite coatings were prepared with the basic materials polyacrylate emulsion, the main fillers flaky mica and calcium carbonate. The damping loss factor and the sound insulation performance in different frequency of materials were tested. The results showed that the sound insulation performance and the damping properties of materials was effectively improved within a certain range through adding the different particle size of the mica as the fillers, but there was bad effect on the combination of interface between macromolecular chains and fillers. By surface modification treatment on the fillers, there was not only enhanced the combination of interface between polyacrylate emulsions and fillers, but also significantly improved the sound insulation performance and the damping properties of materials.
