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.

Key words: montmorillonite,nanocomposite emulsion,paper surface sizing
