摘要
国产PP R管材缺口冲击性能不高、热膨胀系数较大的缺点,采用多种填料、改性剂正交复配的方案进行改性。针对其力学性能和热膨胀性能做了一定的分析。其中。
For improving the notched impact strength and lowering the linear thermal dilatation of PP-R pipes,the latter was modified by adding fillings and additives.The mechanical properties and thermal dilatation of the modified PP-R composite system were definitely analyzed.Most of them was studied with the emphasis on the mechanical properties.
