摘　　要：以贵州大方坡缕石为原料,初步探讨了坡缕石的表面改性工艺条件,经过沉降高度法、红外光谱方法检测和坡缕石与树脂的二元混合试验,证实用硅烷类偶联剂KH-550对坡缕石进行改性可取得一定的增强效果。Using the Guizhou Dafang＇s palygorskite as raw material, the technological conditions for surface modification of palygorskite was preliminarily researched. The nodified palygorskite was evaluated by some measurement methods, such as sedimentation height in different solvent media, infra - red spectrometry, and the dual - mixed tests of palygorskite and resin. The test results confirmed that the silicane coupling agent KH -550 has a certain strengthening effect.
