| 摘 要： | 采用黏均分子质量测定、衰减全反射-傅里叶转换红外光谱（ATR—FTIR）和力学性能测试等方法研究了半补强炭黑（SRF）对增塑PVC的紫外光稳定和降解性能的影响。实验结果表明，SRF的加入能有效提高增塑PVC的抗紫外光性能，由于SRF表面含有较多的活性基团，同时对增塑PVC具有一定的补强作用，所以材料的力学性能有了很大提高。当SRF的添加量为2份时，紫外光照射800h过程中，黏均分子质量的下降得到有效的延缓，力学性能也得到较好保持。

| Abstract: | The effects of semi-reinforcing furnace black on the UV stability and degradation of plasticized PVC were studied by means of viscosity-average molecular weight determination,attenuated total reflection-fourier transform infrared spectroscopy and mechanical properties test.The experiment results showed that the UV light stability of plasticized PVC was significantly improved with the presence of the semi-reinforcing furnace black;because there were many active groups on its surface and it had reinforcement ... |
