摘　　要：采用逆转法,以有机蒙脱土(OMMT)复配乳化剂,制备了OMMT改性石蜡乳液,利用红外光谱、热重分析等手段分别对OMMT改性石蜡乳液的结构进行了表征,同时研究了OMMT改性石蜡乳液对废纸纤维施胶后的接触角和力学性能的影响。结果表明,加入质量分数1%的OMMT改性石蜡乳液,能更显著地提高施胶后的纸张的接触角,其耐水性、撕裂强度、拉伸强度、环压强度、耐破度等也得到明显的提高。扫描电镜对纸张纤维表面的研究表明,加入OMMT改性石蜡乳液后,纸张纤维表面孔洞较少,纤维的结合比较均匀,结构较致密。Organo-montmorillonite （OMMT） modified wax emulsion was prepared by phase inversion process with a mixture of OMMT and emulsifier. The structure of OMMT modified wax emulsion was studied by using fourier transform infrared spectrometer and thermogravimetric analysis. The effects of wax emulsions on the water contact angle and mechanical properties of waste paper fibers were also studied. The results show that the water contact angles are increased markedly; the water resistance, tear strength, tensile strength, ring pressure and burst strength of the waste paper fibers are also improved obviously by adding 1% of OMMT modified wax emulsion. Scanning electron microscope reveals that less voids are found on the surface of the waste paper fibers, which are closer and more homogeneous, after sizing with OMMT modified wax emulsion.
