Study on the process of surface modification of dehydrated palygorskite based on XD-172 silane coupling agent

Three types of dehydrated palygorskites are prepared, and XD-172 silane coupling agents are used to modify dehydrated palygorskite by the drop height method employed to evaluate the effects of surface modification. The optimal modification process parameters are obtained by analyzing the influences of modification agents quality, modification temperature and modification time on drop height, so that it could provide the good basis for further study the friction and wear performance of dehydrated palygorskite.
