岛津气相色谱质谱联用法检测PVC塑料中的增塑剂
关键字：PVC塑料
增塑剂是常用于添加在塑料制品中的化工助剂,它能改善加工性能,赋予制品柔韧性,而被广泛应用。单一类型的增塑剂往往不能满足塑料制品的所有要求，因此通常同时使用多种不同类型的增塑剂。最常用的增塑剂主要有四大类，即邻苯二甲酸酯类、己二酸酯类、磷酸酯类和柠檬酸酯类。增塑剂的广泛应用，对人类的健康危害越来越大。经动物实验表明，邻苯二甲酸酯类增塑剂对人类和动物有雌性激素效应，可以引起内分泌失调，出现生...

51 Flammability properties and electromagnetic interference shielding of PVC/graphene composites containing Fe3O4 Nanoparticles
关键字：graphene/Fe3O4
The effects of combined graphene/Fe3O4 nanoparticles on the flame retardancy and smoke suppression of PVC were studied. The dispersion state of graphene in the PVC matrix was improved with the help of Fe3O4 nanoparticles. As a result, the peak values of heat release rate and smoke production rate measured by cone calorimetry were obviously decreased in the PVC/graphene/Fe3O4 composites. According ...

电石渣增强改性PVC塑料的研究
通过扫描电镜、X射线衍射仪和粒径分析等对电石法生产聚氯乙烯（PVC）过程中产生的废渣——电石渣进行理化性质表征，结果表明，电石渣主要成分是氢氧化钙，且含有少量的镁铁化合物，其中位径为8 μm。将电石渣作为填料应用到硬质PVC塑料中，并采用偶联剂对其改性，研究了偶联剂种类及用量、改性电石渣用量对PVC塑料性能的影响，研究表明，电石渣填充PVC塑料的各项性能与重质碳酸钙填充效果相近，偶联剂KH570改性电石渣效果最好，...

Fielder-Crafts烷基化反应制备二茂铁-g-PVC
由于PVC结构中存在着不稳定的内在缺陷，尤其叔基氯及烯丙基氯的存在使得PVC具有稳定性及耐热性等的不足，通过PVC与二茂铁(Fe)之间的Friedel-Crafts反应，将二茂铁基引入PVC骨架，赋予PVC光、电、磁等新功能，实现PVC功能化，发展PVC在传感器、分析科学及无损检测等新领域的应用。
