| 摘 要： | 合成高沸醇木质素改性松香树脂,测定改性树脂的软化点、酸值和DSC-TGA曲线,并与原料松香进行比较。高沸醇木质素可以与松香反应生成木质素改性松香树脂,其软化点比松香高,酸值比松香低。松香的热稳定性通过高沸醇木质素的改性得到改善。实验结果表明高沸醇木质素改性松香比木质素磺酸盐效果更好。

| Abstract: | High boiling solvents(HBS) lignin modified rosin was successfully synthesized by rosin and HBS lignin.These resins were characterized by acid value,soft point,DSC-TGA,and compared with rosin.HBS lignin could react with rosin to form lignin-modified resin.The soft point of lignin-modified resin was higher and the acid value was lower than rosin.The heat resistance of rosin was improved by HBS lignin modification.The results showed that the modification of HBS lignin has better effect on the properties of rosin than lignin sulfonate. |
