Title: Study on the Preparation of Functional Acrylic Emulsion and its Properties
Abstract: Room temperature self-crosslinking acrylic emulsions were prepared by adding several functional monomers and using LX and TX-10 as the composite emulsifiers by semi-continuous emulsion polymerization. The effects of acrylic acid (AA) content and the dropping time of monomers on the
viscosity of emulsion, the cross-linking level and the percentage of water-uptake of emulsion film were addressed. It was shown that the viscosity of acrylic emulsion and the cross-linking level of the emulsion film increases with the increase of AA content while the percentage of water-uptake of the film descends first and then ascends with the increase of AA content. Meanwhile, it was found that the average diameter of the emulsion particles becomes smaller and the size distribution becomes narrower with the increase of dropping time of monomers; Accordingly, the viscosity of the acrylic emulsion descends, the cross-linking level of the emulsion film increases and the percentage of water-uptake of the film decreases.
