| 摘 要： | 分别采用硬脂酸和硅烷偶联剂对阻燃剂Mg(OH)2进行表面处理,研究了Mg(OH)2的表面处理方法对聚丙烯(PP)复合材料熔体流动性能和阻燃性能的影响。结果表明,经表面处理的Mg(OH)2与PP组成的复合材料的加工性能得到明显改善,对材料的阻燃性能没有明显影响。相同条件下,硅烷偶联剂比硬脂酸的改性效果更好,酸化水解条件对硅烷偶联剂的改性效果没有影响。

| Abstract: | The surface of magnesium hydroxide(Mg(OH)2) was modified with stearic acid and silane coupling agent respectively.The influences of the surface modification of Mg(OH)2 on the melt flowability and flame retardancy of the PP composites were investigated.The results showed that the surface modification of Mg(OH)2 could improve the processability of PP/Mg(OH)2 composites obviously, but has no distinct influence on the flame retardant of the composites.Under the same conditions, the modification effects of silane was better than those of stearic acid.Acidified hydrolysis condition had no effect on the modification effect of silane. |
