Zinc hydroxystannate (ZHS) coated dendritic-fibrillar barium carbonate (ZHS/BaCO3-F) was obtained by a simple ultrasonic assisted method at room temperature without any guide reagent; the flame retardant soft poly (vinyl chloride) (S-PVC) treated with ZHS/BaCO3-F was prepared by melt blending and studied by the limiting oxygen index (LOI), univeral tensile testing machine, thermogravimetric analyzer-Fourier transform infrared spectroscopy (TGA/FTIR), scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results showed that ZHS/BaCO3-F had a good dispersion in the PVC matrix, increased the LOI value and reinforced the S-PVC. The ZHS/BaCO3-F played its role during the first degradation stage of S-PVC; the integrated effects of the earlier dehydrochlorination of ZHS on PVC, the reaction of ZHS/BaCO3-F and HCl, and the thermal degradation of ZHS resulted in the production of H2O, CO2, olefins, aryl compounds, carboxylic compounds and alcohols, and the decrease of HCl production.

羟基锡酸锌包覆树突状原纤化碳酸钡的制备及其对软质聚氯乙烯的阻燃作用
羟基锡酸锌(ZHS)涂覆的树突-纤维状碳酸钡(ZHS /的BaCO 3-F )中的溶液在室温下没有任何导试剂的简单超声辅助法获得; 通过熔融共混制备了用ZHS / BaCO 3-F处理的阻燃软质聚氯乙烯(S-PVC),并通过极限氧指数(LOI),通用拉伸试验机,热重分析仪-傅里叶变换红外光谱进行了研究。 (TGA / FTIR),扫描电子显微镜(SEM)和X射线衍射(XRD)。结果表明,ZHS / BaCO 3-F在PVC基体中具有良好的分散性,提高了LOI值,并增强了S-PVC。ZHS / BaCO 3-F在S-PVC的第一个降解阶段发挥了作用;ZHS早期脱氯化氢对PVC的综合作用,ZHS / BaCO 3-F与HCl的反应以及ZHS的热降解导致产生H 2 O,CO 2,烯烃,芳基化合物,羧酸化合物和酒精,并减少HCl的产生。
