以鑭系羧酸鹽添加劑摻合礦物粉體對聚丙烯的熱變化性質之研究

本論文主要分為兩部份並加以論述: (一)合成含有鑭系金屬的新型液態分散劑本研究利用新穎方法將La2O3與Carboxylic acid (RCOOH)反應成La(OOC-R)3，並且討論如何將其反應產物呈現液態均勻相，以便於添加於聚丙烯中，作為一新型分散劑。 (二)鑭型液態分散劑與礦物粉體添加對聚丙烯導熱性質之討論以合成之鑭型羧酸錯合物，分別以不同比例添加量加至礦石粉體中，再以此混合之固液混合分散劑加至聚丙烯母粒中，先進行混煉製程，之後再做破碎處理然後進行最後階段的射出成型。以此對照當聚丙烯添加入分散劑時，探討前後熱導性質的差異，包括聚丙烯加工時的熱導係數及分散性及其加工射出成型產品之熱導、散熱等性能上的影響。

The content of this thesis is described as follows: (I)Synthesis of Lanthanium Carboxylate Dispersant This research introduced a new mode of experiment to esterify La2O3 and Carboxylic acid (RCOOH) into La(OOC-R)3.We have also been explored how to make it liquified in a uniform phase and then to be used as a dispersant to Polypropylene. (II)The Discussion of Lanthanium Carboxylate Additive on Ore Powder for the Thermal Properties of Polypropylene The new synthesis of lanthanium carboxylate was added in several different percentage with ore powder.Then, the complex dispersant was added into the polypropylene resin plastic particle.This raw material was mixed, broken and then prepared as PP sheets.Forthermore, the thermal properties of polypropylene with various percentage of additive components were discussed including of the thermal conductivity and dispersivity in pp sheets.We also examined several influences of thermal properties in final products of PP sheets, e.g thermal conductivity and radiation.
