【摘要】 以钙基膨润土为原料,十八/十六烷基氯化铵为有机改性剂,采用水热合成法制备出黏度值5.0Pa·s、d(001)值20.532的有机改性膨润土。在环氧防锈漆中的对比应用试验表明:该有机改性膨润土在油漆中增稠效果、防沉效果良好,可显著改善油漆的贮存稳定性。更多还原

【Abstract】 The organic modified bentonite is synthesized using Ca-bentonite as matrix and octadecyl/hexadecyl ammonium chloride as the cover agent,by hydrothermal process.Its viscosity is 5.0 Pa·s and the d(001) value is 20.532?.The application contrast experiment indicates:The organic modified bentonite has a good thickening effect and a good antisedimentating effect in the epexy-regin antirusting paint. It can improve the storage stability of the paint effectively.更多还原
