钛酸酯偶联剂表面改性煤矸石粉的研究
Study on Surface Modification of Coal Gangue Powder by Titanate Coupling Agent
摘要
Abstract
Based on the methods of XRD and SEM,the surface performance,microstructure and modified powder of the Coal Gangue Powder（CGP） modified by Titanate Coupling Agent are studied,and the effect of the CGP is analyzed after modification on the mechanical performance of high-density polyethylene（HDPE） composite materials.The modified CGP changed from hydrophilic to lipophilic in the experiment of mechanical property;the SEM photographs also shows that the modified CGP has good compatibility with HDPE;the mechanical test shows that the modified powder has significantly improved the mechanical performance of composite materials.When the filler content is 30%,the flexural strength increases 71.7%,and the tensile strength also increases 19.3%.The mechanism of coal gangue powder modified by titanate coupling agent is also described.关键词
