摘要
采用逆转法制备了有机蒙脱土(OMMT)改性松香乳液,利用X-射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、热分析(TGA)、差示扫描量热(DSC)和扫描电镜(SEM)等分别对有机改性蒙脱土(OMMT)及松香乳液的结构进行了表征,同时研究了OMMT改性松香乳液对废纸纤维施胶后的耐水性能和力学性能的影响。结果表明,OMMT在试验中对松香乳液的玻璃化温度(Tg)没有产生明显的影响,但显著地提高了施胶后的废纸纤维的耐水性和力学性能。
Organo-montmorillonite （OMMT） modified rosin emulsion was prepared by inversion process. The structure of OMMT and rosin emulsion was studied by using X-ray diffraction （XRD）, Fourier transform infrared spectroscopy （FTIR）, thermal gravimetric analysis （TGA）, differential scanning calorimetry （DSC） and scanning electron microscope （SEM）. The effects of rosin emulsion on the water resistance and mechanical properties of waste paper fibers were also studied. The results show that glass-transition temperature （Tg） of the rosin emulsion were not changed by the incorporation of OMMT. The water resistance, and mechanical properties of waste paper fibers were also improved obviously after adding of OMMT modified rosin emulsion.
