摘要
为降低汽车内饰材料中的挥发性有机物(VOC)含量,采用吸附和机械共混法制备聚对苯二甲酸乙二酯(PET)/己二酸二酰肼-气凝胶(ADH-AG)复合材料,并通过差示扫描量热仪、万能材料试验机和高效液相色谱仪等对复合材料的热性能、力学性能和VOC含量等进行测试与分析。研究发现,随ADH-AG含量增加,PET/ADH-AG复合材料的熔融温度和熔融焓值逐渐降低,结晶温度呈现先提高后降低的趋势。ADH-AG的加入能够提高复合材料的力学性能,降低复合材料的VOC含量。当ADH-AG含量为PET的0.75%时,PET/ADH-AG复合材料的拉伸强度达到最大值81.13 MPa,VOC含量最低,其中甲醛、乙醛和丙酮去除率分别达88.2%,92.1%和85.9%。
In order to reduce the content of volatile organic compounds(VOC)in automotive interior materials,polyethylene terephthalate(PET)/dionyl hydrazine adipate-aerogel(ADH-AG)composites were prepared by adsorption and mechanical blending methods.The thermal properties,mechanical properties and VOC content of composites were studied and analyzed by differential scanning calorimetry,universal material testing machine,high-performance liquid chromatography and so on.The results show that with the increase of ADH-AG content,the melting temperature and melting enthalpy of PET/ADH-AG composites gradually decrease,and crystallization temperature shows a trend of firstly increasing and then decreasing.The addition of ADH-AG can improve the mechanical properties and reduce the VOC content of composites.When 0.75%of ADH-AG is incorporated,the composites reach the maximum tensile strength value of 81.13 MPa and the minimum VOC content,the removal rates of formaldehyde,acetaldehyde and acetone are as high as 88.2%,92.1%and 85.9%,respectively.
