Influence of Acrylic Emulsion on Polymer-Cement Waterproof Coating

Abstract:

In this study, effects of polymer-cement (P/C) ratio, glass transition temperature (Tg); amounts of functional monomers (acrylic acid, hydroxypropyl methacrylate, ammonium polyacrylate, diacetone acrylamide) on properties of polymer cement mortar were investigated. According of the tensile test, breaking elongation (ε) and the tensile strength (δ) of polymer latex-cement composites with low P/C ratio were mainly depended on Tg, differential Tg value between layer and shell in acrylic latex (ΔTg) and the amounts of functional monomer. Additionally, at a low P/C ratio, it was found that the cross-linking rate had small effect of tensile property. It was determined that the waterproofing coatings III with a low P/C (0.12) showed the excellent tensile property when the Tg and the ΔTg of the acrylic latex were controlled at -24°Cand -20°C, respectively.
