| 摘 要： | 目的确定最佳偶联剂及其用量,以改进聚乙烯薄膜的综合性能。方法采用铝酸酯、钛酸酯、硬脂酸等偶联剂对滑石粉进行表面改性,通过测定改性后滑石粉的接触角、活化率以及红外光谱等方法对改性效果进行评价。并将改性后的滑石粉与聚乙烯共混后进行吹塑薄膜,测定薄膜的力学性能。结果采用偶联剂改性滑石粉后,表面从亲水性变为疏水性,其中钛酸酯表面改性效果较好。表面改性提高了滑石粉填充聚乙烯薄膜的力学性能。结论使用质量分数为2%钛酸酯改性的滑石粉作为填充粉体时,聚乙烯薄膜的综合性能较好。

| Abstract: | The work aims to determine the better coupling agent and its dosage to improve the properties of polyethylene film.The talc powder was modified by aluminate,titanate,stearic acid and other coupling agents.The modified talc powder was evaluated by measuring its’contact angle,activation rate and FTIR.The modified talc powder was blended with polyethylene and blown into film and the mechanical properties of the films were measured.The surface of talc powder modified by coupling agent changed from hydrophilicity to hydrophobicity,and the surface modification effect of titanate was better.Surface modification improved the mechanical properties of talc powder filled polyethylene films.When talc powder modified by 2%titanate is used as powder,the comprehensive properties of polyethylene film are better. |
