摘　　要：研究开发了一种新型的羧酸金属盐β晶型成核剂。此成核剂不仅高效诱导β-PP形成,而且成核效率高,β-成核PP的冲击强度可提高2~4倍,并且大幅提高PP热变形温度,有效缓解了聚丙烯制品的冲击强度和热变形温度二者之间的矛盾。目前已在PPR管材和PPH板材、大注件制品以及锂电池隔膜方面得到广泛的应用。A new type of carboxylic acid metal salt β-crystalline nucleating agent is developed. It is a new compound. This nucleating agent not only efficiently induces the formation of β-PP, but also has a high nucleation efficiency. The impact strength of β-nucleating PP can be increased by 2 to 4 times, and the heat deformation temperature of PP can be greatly increased. The contradiction between the impact strength and the thermal deformation temperature of polypropylene products is effectively relieved. At present, it has been widely used in PPR tubes and PPH plates, large injection products, and lithium battery diaphragm.
