【摘要】 将粘土经还原剂及酸处理 ,再与天然胶乳共沉制备粘土胶复合材料 ,用带原位样品池的傅立叶变换红外光谱仪动态研究粘土胶复合材料在不同温度下热降解气相产物。在低分解温度下 ,粘土胶分解产物主要是乙烯、低分子烯烃类及含羰基化合物 ;随分解温度升高 ,则低分子烯烃含量减少 ,较长链烯类生成 ,并同时产生大量烷烃类分解产物。随着粘土中 Cu,Mn,Co,Fe等金属组分含量升高 ,粘土胶分解产物中含羰基氧化产物、烯烃及 CO2 含量增加 ,说明金属组分对粘土胶降解氧化产生促进作用

【Abstract】 After treating by reductant and inorganic acid, the clays were coagulated with natural latex to prepare natural rubber clay composites. The composites were studied in different decomposition temperatures by using in situ FTIR. In lower decomposition temperature, the decomposing gaseous products of the composites mainly were ethylene, lower molecular weight olefin and carbonyl compounds. With the increase of degradation temperature, the contents of lower molecular weight olefin reduce and more higher molecular weight olefin and alkyl compounds form. Furthermore, with the increase of the contents of the metal component in the clay, such as Co, Mn, Cu and Fe, the decomposing gaseous products contain more olefin and carbonyl compounds as well as CO 2. The metal components in the clay accelerate the oxidative degradation of natural rubber/clay composites.
