高表面低翘曲玻纤增强PA复合材料的制备和性能研究

Preparation and Properties Study of GF Reinforced PA Composite with Low Warpage and Better Suface

依据玻纤增强尼龙(PA)表面不良,翘曲的机理,选用不同提高表面质量的方法,制备了系列高表面低翘曲玻纤增强PA复合材料。结果表明:具有较高形状对称性的填料,如碳酸钙、滑石粉、云母粉和玻璃微珠都能不同程度地提高玻纤增强PA体系的表面质量,降低翘曲;自制的抗浮纤母粒,结晶慢的聚合物也都能有效改进该体系的表面质量。

Series of glass fiber reinforced PA with low warpage and better surface were been prepared in different methods with the mechanism analyzed. The results showed that the mineral filler such as CaC03, talc, mica, glass microsphere with a high symmetrical shape, can decrease the warpage of PA/GF system and increase the surface quality. The self-made anti-floating fiber master batch and the polymer with slow crystalization can also improve the performance in the system.
