采用不同的助剂(MBS、CPE、NBR)对W-EP/PVC(废环氧树脂/PVC)复合材料进行增韧改性,并对改性后的复合材料进行表征。结果表明,单一助剂的添加可显著提高冲击强度,但拉伸强度有所降低;助剂的加入均会使共混体系流变性能有一定程度降低;粉末丁腈橡胶中丙烯腈含量影响复合材料力学性能。MBS和粉末丁腈橡胶P83的改性效果较好,两者组成的双改性剂具有协同作用,且MBS/P83添加比例为7/3时,复合材料性能达到最佳。
Different additives (MBS, CPE, NBR) were used to toughen the W-EP / PVC composites and the composites were characterized. The results show that the addition of a single additive can significantly increase the impact strength, but the tensile strength decreases; the addition of additives will make the rheological properties of the blend system to some extent reduce; acrylonitrile content of the impact of the composite nitrile rubber compound Mechanical properties of materials. MBS and powder Nitrile P83 modified better, the two modifiers with synergistic effect, and MBS / P83 addition ratio of 7/3, the composite material to achieve the best performance.
