摘要/Abstract

摘要：

为提高聚氯乙烯(PVC)复合膜材的阻燃性能并降低Sb2O3的使用量，制备了羟基锡酸锌(ZHS)；利用X射线粉末衍射仪、傅里叶红外光谱仪和场发射扫描电镜对制备的样品进行了测试。测试结果显示制备的样品为边长1μm左右的立方体ZHS。将ZHS等助剂添加到PVC糊料中制备了具有阻燃作用的膜材涂层材料，通过极限氧指数、热重分析、扫描电镜炭渣形貌的方法，探讨了PVC复合涂层材料的阻燃作用。结果表明：添加ZHS的PVC材料的残炭量高于添加Sb2O3的PVC材料且炭渣表面更致密；而添加ZHS/Sb2O3（1:1）的PVC材料的极限氧指数（LOI）高于两者单独使用，即ZHS和Sb2O3对PVC涂料存在协同阻燃效应，从而降低Sb2O3在阻燃PVC涂层材料中使用量。

Abstract:

To improve the flame retardance of PVC-coated material and decrease the content of Sb2O3, we preparated zinc hydroxy-stannate (ZHS) and it was studied by X-ray diffraction, fourier transformation infrared spectroscopy and scanning electron microscopy images. The result showed that the preparated sample was in the form of cubic single-crystals having particle size of 1μm. PVC compound coated material was prepared by a blending method. Flame retardancy and relevant mechanism were investigated by means of limited oxygen index, thermogravimetry, and SEM. The results showed that PVC-coated material with ZHS has higher carbon residue rate than that PVC-coated material with Sb2O3, and the flame retardance of PVC with ZHS/Sb2O3 is higher than that with ZHS or Sb2O3 individually. Namely, there is a significant synergistic flame-retarded effects between ZHS and Sb2O3 on the PVC-coated materials, decreasing the content of Sb2O3 in PVC-coated material.
