物流包装用PP/CSW/hBN复合材料力学及摩擦性能

摘要
目的研究不同质量分数六方氮化硼对聚丙烯/硫酸钙晶须复合材料力学性能的影响。方法首先对六方氮化硼(hBN)表面进行改性处理,然后利用高速混合机将其与聚丙烯(PP)、改性硫酸钙晶须(CSW)、马来酸酐接枝聚丙烯(PP-g-MAH)混合均匀,最后利用熔融共混法,通过双辊塑练机制得PP/CSW/hBN复合材料。结果当添加hBN的质量分数为1%~1.5%时,pp/csw/hbn复合材料的力学性能最佳;hBN质量分数为1.5%时,复合材料的摩擦因数和磨损率最低。结论 hBN经过表面改性处理后,其在复合材料中分散性得到了改善,与聚丙烯基体界面间的结合力也得到提高,表现为对聚丙烯复合材料起到了补强、增韧和耐磨的作用。当hBN的质量分数达到一定量时,其在复合材料内部会出现团聚现象,从而降低复合材料的力学性能和摩擦性能。
The work aims to study the effects of hexagonal Boron Nitride with different mass frictions on the mechanical properties of PP/calcium sulfate whisker. First of all, the surface of hexagonal Boron Nitride(hBN) was modified. Then, hBN was evenly mixed with polypropylene(PP), modified calcium sulfate whiskers(CSW) and maleic anhydride grafted polypropylene(PP-g-MAH) by high-speed mixer. Finally, the twin-roll plastic refining machine was used to prepare PP/CSW/hBN composites by the method of melt blending. The results showed that, when the mass friction of hBN was about 1%~1.5%, pp/csw/hbn had the best mechanical property. When the mass friction of hBN was 1.5%, the friction coefficient and wear rate of the composite were the lowest. After the hBN surface is modified, its dispersity in the composite is improved and the binding force between hBN and polypropylene matrix interface is improved, which has an effect on the performances of reinforcement, toughening and abrasion resistance of PP composites. When the mass fraction of hBN reaches a certain amount, agglomeration will occur inside the composites, thus reducing the mechanical and fraction properties of composites.
