摘要
(CN105038159B) 本​发明​公开​了​含​反应​性​大分子​型​成​核​剂​的​聚​乳酸​复合材料​及其​制备​方法,属于​生物降解​高分子​材料​领域。其​组成​成分​及​重量​分数​配比​为:聚​乳酸​100​份,酚醛​模塑​粉​0.3​~​1​份,乌洛托品​0.06​~​0.14​份,分散剂​10​~​20​份,功能​添加剂​0.5​~​1​份。本​发明​还​公开​了​上述​含​反应​性​大分子​型​成​核​剂​的​聚​乳酸​复合材料​的​制备​方法。本​发明​中高​分子​型​成​核​剂​能​均匀​分布​于​聚​乳酸​基材​中,克服​了​传统​无机​成​核​剂​由于​与​基体​材料​之间​强烈​的​界面​排斥​而​导致​基体​材料​结晶​不均,大大​改善​了​聚​乳酸​的​结晶​行为​和​力学​性能。

主权利要求
(CN105038159B) 1. One reactive macromolecular type polylactic acid composite material of the nucleating agent, characterized in the following percentages by mass and the components thereof: Polylactic acid 100 parts Phenolic molding powders 0.3-1 parts Urotropin 0.06-0.14 parts Dispersant 10-20 parts Functional additives 0.5-1 parts; According to the following steps: Preprocessing of (1) raw materials: the polylactic acid, a phenolic molding powder was placed in a vacuum oven drying 5 hours standby; methenamine dissolved with an appropriate amount of ethanol was dropped, methenamine solution sprayed uniformly with the configured surface molding powders and sufficiently mechanically mixed in a phenolic, placed in a vacuum oven drying; Composite (2) material of melt blending: the step (1) of the polylactic acid, a phenolic molding powder was mixed uniformly in a step (1) while adding urotropin and a twin-screw extruder melt-blending extruder, the extruder screw temperature in the range of 150-180 Ć, the screw speed was 100-200 rpm, an aspect ratio of screw 15-48, and then the extruded product was pelletized, dried, using an injection molding machine to prepare a standard spline, finally, the standard spline is subjected to mechanical testing.
