防紫外线聚酰胺母粒的制备与性能研究

Preparation and Property of Anti-ultraviolet Polyamide Chip

应用透射电镜对纳米SiO2 -x和TiO2 进行了测试 ,这两种纳米材料经表面改性后 ,按一定的配比与粉碎后的聚酰胺粉末共混、挤出、切粒 ,再将聚酰胺母粒制成薄膜 ,用紫外分光光度计测试其紫外线透过率 ,并测试防紫外线聚酰胺母粒的性能。讨论了影响聚酰胺母粒抗紫外线性能的因素。

Test the nanometer SiO_ 2-x and TiO 2 by TEM. After surface modification, these two nano-materials were mixed together with powdered polyamide in proportion, extruded and chipped, then made into film. Test its transparency of ultraviolet by UV-spectrophotometer and the properties of anti-ultraviolet of polyamide chip. Discuss the factors that affect the anti-ultraviolet properties of polyamide chip.
