Ameliorating the Mechanical Parameters, Thermal Stability, and Wettability of Acrylic Polymer by Cement Filling for High-Efficiency Waterproofing

Acrylic polymer/cement nanocomposites in dark and light colors have been developed for coating floors and swimming pools. This work aims to emphasize the effect of cement filling on the mechanical parameters, thermal stability, and wettability of acrylic polymer. The preparation was carried out using the casting method from acrylic polymer coating solution, which was added to cement nanoparticles (65 nm) with weight concentrations of (0, 1, 2, 4, and 8 wt%) to achieve high-quality specifications and good adhesion. Maximum impact strength and Hardness shore A were observed at cement ratios of 2 wt% and 4 wt%, respectively. Changing the filling ratio has a significant effect on the strain of the nanocomposites. The contact angle was increased as the concentration of additives and cement increased, indicating that the synthesized coating is not hydrophilic and does not allow water permeability through it. The results show that the acrylic polymer/cement with a cement ratio of 8 wt% is the best nanocomposite for high-efficiency waterproofing.

Automated summary

Acrylic polymer/cement nanocomposites have been developed for coating floors and swimming pools. The study shows that the filling of cement has a significant effect on the mechanical parameters, thermal stability, and wettability of acrylic polymer. The best impact strength and hardness are observed at cement ratios of 2 wt% and 4 wt%, respectively. Changing the filling ratio greatly affects the strain of the nanocomposites. The contact angle increases with the concentration of additives and cement, indicating excellent waterproofing properties of the synthesized coating.
