Abstract

Bean dreg (BD)-hydrocalumite composites were prepared by a hydrothermal method with BD, Ca(OH), Al(OH), and NaCO as raw materials. The samples were characterized by powder X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, and N physical adsorption-desorption. Their properties as a thermal stabilizer for poly(vinyl chloride) were tested using a torque rheometer and static thermal aging method. Compared with traditional hydrocalumite, the crystal size of the BD-hydrocalumite composite was relatively small, which made it exhibit good dispersion and better thermal stability for poly(vinyl chloride). In addition, the effects of preparation conditions on the properties of BD-hydrocalumite as a heat stabilizer were also investigated. Under the conditions of [Ca(OH)/Al(OH)/NaCO] = 4.4:2:1, a BD dosage of 5%, a crystallization temperature of 90 °C, and 19 h, the prepared BD-hydrocalumite showed the best performance, and the dynamic thermal stability time of poly(vinyl chloride) reached 2149 s.

摘要

以豆渣（BD）、Ca(OH)₂、Al(OH)₃和Na₂CO₃为原料，采用水热法制备了豆渣-水滑石复合材料。通过粉末X射线衍射、扫描电子显微镜、傅里叶变换红外光谱和N₂物理吸附-脱附对样品进行了表征。使用转矩流变仪和静态热老化方法测试了它们作为聚氯乙烯热稳定剂的性能。与传统水滑石相比，豆渣-水滑石复合材料的晶体尺寸相对较小，这使其在聚氯乙烯中表现出良好的分散性和更好的热稳定性。此外，还研究了制备条件对豆渣-水滑石作为热稳定剂性能的影响。在[Ca(OH)₂/Al(OH)₃/Na₂CO₃]=4.4:2:1、豆渣用量为5%、结晶温度为90℃和19 h的条件下，制备的豆渣-水滑石表现出最佳性能，聚氯乙烯的动态热稳定时间达到2149 s。
