磷酸酯盐类成核剂对煤基抗冲共聚聚丙烯K8708结晶和力学性能的影响研究OA北大核心
Effect of phosphate nucleating agents on crystallization and mechanical properties of coal-based impact-resistant copolymerization-type polypropylene K8708
通过两种磷酸酯羟基铝盐成核剂NA-21和TD-531对煤基抗冲共聚聚丙烯K8708结晶过程的影响研究,实现抗冲共聚聚丙烯的力学性能调控.结果表明,两种成核剂均为聚丙烯(PP)α型成核剂,可显著提高PP的结晶峰温度和结晶成核密度,进而加速其整体结晶速率,实现其刚性和加工效率的双提升.其中成核剂TD-531相对于NA-21对PP性能提升的作用更为明显,在添加量仅为0.075%时,不仅可使PP的结晶峰温度和半结晶时间分别提升和降低至131.8℃和0.3…查看全部>>
The effect of two types of phosphate ester hydroxyaluminum salt nucleating agents,NA-21 and TD-531,on the crystallization process of coal-based impact-resistant copolymerization-type polypropylene(PP)was investigated,re-alizing the regulation of the mechanical properties of the PP.The results indicated that both of the nucleating agents could act as α-Type nucleating agents for the PP to significantly increase its crystallization peak temperature and nucle-a…查看全部>>
