聚合物/蒙脱土纳米复合乳液的制备及其表面施胶性能

摘要/Abstract

摘要：

采用蒙脱土(MMT)改性聚苯乙烯-丙烯酸酯(PSB)乳液制备了一种新型表面施胶剂。比较了不同方法合成的乳液在性能上的异同。采用X射线衍射（XRD）和透射电子显微镜（TEM）测试技术表征了复合材料的结构。研究了苯丙/蒙脱土纳米复合乳液作为表面施胶剂对纸张的物理性能和抗水性能的影响。结果表明，聚合法制备的复合乳液中蒙脱土片层已发生剥离并在复合物中呈现纳米级分散。纳米复合乳液与淀粉以质量比1∶10（绝干）复配进行表面施胶时，纸张的施胶度、挺度和环压强度比纯苯丙施胶剂分别提高1.8倍、45.5%和44%。

Abstract:

A kind of new surface sizing agent was prepared from polystyrene-acrylate(PSB) emulsion modified with montmorillonite(MMT). The effects of different processes on emulsion properties were studied. The structure of the nanocomposite emulsion was characterized by X-ray diffraction(XRD) and transmission electron microscopy(TEM). The effects of PSB/MMT nanocomposite emulsion as surface size on physical properties and water resistance of paper were studied. The result shows that montmorillonite in the emulsion exfoliated, and the dispersion of MMT reached nano-level. When sizing agent was about 10% of starch, the increase of paper's sizing value, stiffness and ring crush were 1.8 times, 45.5% and 44%, respectively.
