摘要： 以聚乙烯为基础,通过等离子体接枝方法接枝甲基丙烯酸.研究了接枝反应条件对接枝率的影响,并对接枝样品的阻燃性能进行了表征.接枝后样品的点燃时间明显延长,极限氧指数明显提高,成炭量明显增加,说明接枝后的侧基(—COOH,—COO-Na+和—COO-K+)在热降解过程中不仅自身参与成炭,而且大大促进了基体聚合物的成炭过程.

Abstract: An attempt has been made in this study to render polymers flame retardancy by a grafting method induced by plasma. Based on polyethylene, it was found that the grafting yield was influenced by the grafting reaction conditions when polyethylene was grafted with methylacrylic acid. The flame retardancy of the grafted sample was characterized. It was found that the time to ignition of the grafted sample was extended. The limiting oxygen index and char residue were increased. This indicates that the side groups of —COOH,—COO-Na+and—COO-K+ the grafted layer can not only be charred in the thermal degradation stage, but also promote the charring of the substrate polymer.
