摘要
为制备新型轻质隔声复合材料,以聚氯乙烯(PVC)为基体材料,中空微珠(HGM)为基体的填充材料,柠檬酸三丁酯为增塑剂,涤纶织物为增强材料,自制二氧化硅/柠檬酸三丁酯上浆剂为界面优化剂,采用接触成型技术制备了涤纶织物/PVC-HGM复合材料,并利用双声道声学测试仪对复合材料的隔声性能进行测试。结果表明:相同厚度的涤纶织物/PVC-HGM复合材料试样,随着HGM体积分数的增加,复合材料的面密度呈线性下降;HGM体积分数的增加不能显著提高涤纶织物/PVC-HGM复合材料的隔声性能;随着HGM粒径的增大,HGM体积分数相同的涤纶织物/PVC-HGM复合材料的隔声性能明显提高。
In order to prepare a light sound insulation composite,polyester fabric/polyvinyl chloride(PVC)-hollow glass microspheres(HGM)composites were prepared by contact molding technology with polyvinyl chloride as matrix materials,hollow microspheres as matrix filling materials,tributyl citrate as plasticizers,polyester fabric as reinforcement materials,and self-made silica/tributyl citrate sizing agent as interface optimization agents.The sound insulation performance of the composites was tested by using a double-channel acoustic tester.The results show that the mass of the composites decreases linearly with the increase of HGM volume fraction for the same thickness of polyester/PVC-HGM composites.The increase of HGM volume fraction did not significantly improve the sound insulation performance of polyester fabric/PVC-HGM composite.With the increase of HGM particle size,the sound insulation performance of polyester fabric/PVC-HGM composites with the same volume fraction of HGM was significantly improved.
