塑料制品的添加剂——成核剂的分类及研究

Classification and Study on Nucleator as Additive of Plastic Product

成核剂是促进聚合物结晶并改善其晶粒结构的改性剂 ,它主要包括无机类成核剂、有机类成核剂和高分子类成核剂。在聚合物中加入成核剂 ,加快了结晶速度 ,使聚合物的晶粒结构细化 ,缩短了成形周期 ,改善了产品的物理机械性能 ,使产品具有良好的加工和使用性能。

The nucleator is the modified agent to promote polymer crystallization and improve the crystal structure. It mainly includes inorganic, organic and high molecular nucleator. After adding nucleator in polymer, crystallization speed is quickened, crystal structure is fined, shaped period is shortened. The plngsical mechanical properties of the proclicts are improved.That makes the products to have favorable processing and application properties.
