| 摘 要： | 采用碱煮法、酸解法和溶剂法从橡胶草根中提取蒲公英橡胶,并对提取后橡胶的组分和结构性能进行了初步分析。结果表明,溶剂法提取蒲公英橡胶的纯度较高;通过红外光谱和核磁共振波谱的分析可知,蒲公英橡胶的结构与三叶天然橡胶大致一样;蒲公英橡胶的交联密度则低于三叶天然橡胶;在分子量及其分布上,蒲公英橡胶的分子量小于三叶天然橡胶,且分子量分布较窄和较均匀;蒲公英橡胶的塑性初值和门尼黏度低于三叶天然橡胶,其后续生产加工存在一定难度。

| Abstract: | Rubber was extracted from Taraxacum kok-saghyz (TKS) by alkali, acid and solvent methods. The composition and structure properties of the extracted TKS rubber were analyzed. The purity of TKS rubber was the highest by the solvent method. According to the analysis of IR and NMR, the structure of TKS rubber was similar to that of Hevea rubber. The cross-linking density of TKS rubber was lower than that of Hevea rubber. The molecular weight,of TKS rubber was smaller than that of Hevea rubber, and the molecular weight distribution was narrower and more uniform. The P0 and Mooney viscosity of TKS rubber was much lower than that of Hevea rubber, so it is difficult to produce and process the TKS rubber. |
