【摘要】 利用原子力显微镜(AFM)对玻璃纤维(GF)增强硬质聚氨酯(PUR-R)泡沫塑料体系的界面相结构进行了表征,并研究了经不同偶联剂处理的玻纤增强聚氨酯体系的力学性能。AFM测试结果表明,聚氨酯类偶联剂在玻纤上覆盖的均匀性优于硅烷偶联剂,在玻纤上的成膜厚度约为1μm。力学性能测试结果表明,经聚氨酯类偶联剂处理的玻纤所增强的PUR-R的力学性能稍好。更多还原

【Abstract】 By using AFM( atomic force microscopy) ,the interface morphology of polyurethane/glass fiber(GF/PU R)was s-ludied. The influence of two different coupling agents, namely, polyurethane coupling agent and silane coupling agent(GH-550) on glass fiber surface was investigated. The results showed that polyurethane coupling agent was superior to KH-550, due to partly the better interaction between polyurethane coupling agent and the matrix. The thickness of the interface was found approximate to 1m with polyurethane coupling agent. Even there exists a big difference between the interfaces of the composites by using two kinds of coupling agent, the mechanical properties of two types of surface modified glass fiber loaded rigid polyurethane foams are not very much different.更多还原
