摘要: 利用氯化聚乙烯(CPE)、2,2-亚甲基-双( 4-甲基-6-叔丁基苯酚) (AO 2246)和三维卷曲七孔中空涤纶纤维(SHPF)分别制备了CPE-AO 2246和SHPF/CPE-AO 2246一系列的阻尼复合材料。通过傅立叶红外光谱仪和扫描电镜对材料中缔结的氢键和微观结构进行了测试与分析。结果表明:在高温热压条件下, CPE-AO 2246复合材料在3528cm-1、3505cm-1处形成了新的吸收峰。在未热压的CPE-AO 2246中随处可见AO 2246的结晶体,而经热压工艺的到处是CPE-AO 2246的杂化态;随纤维的加入,CPE-AO 2246复合材料在758.4cm-1、775.5cm-1处形成新的吸收峰,复合材料中AO 2246的结晶体明显增多,只有少量的AO 2246相容于CPE中形成“亚杂化态”。这为进一步揭示有机杂化材料的阻尼机理提供了依据。

Abstract: A series of CPE-AO 2246 and SHPF/CPE-AO 2246 damping composites were prepared with chlorinated polyethylene (CPE), 2,2′-methylene-bis-(6-tert-butyl-4-methyl-phenol)(AO2246) and seven hole hollow polyester fibers( SHPF). Hydrogen bond formation and microstructure of composites were measured and investigated by means of FT-IR and SEM. The results showed that new absorption peak was formed in the 3528cm-1 and 3505cm-1 in CPE-AO 2246 composite which was made by hot pressing conditions of high temperature. AO 2246 crystals were seen everywhere in CPE-AO 2246 composite without hot-pressed while there were full of CPE-AO 2246 hybrids in hot-pressed CPE-AO 2246 composite; with adding SHPF, new absorption peak was formed in the 758.4cm-1 and 775.5cm-1 in CPE-AO 2246 composites, AO 2246 crystal significantly increased, and sub-hybrids were formed by a small amount of AO 2246 compatible with CPE. These constituted evidences of further revealing damping mechanism of the organic hybrid material.
