Epoxy-Cement Compositions with effect of thermo-hardening at hard heat treatment for Applied Engineering & Technologies
The composites “epoxy resin – microdispersed cement” were obtained and studied in a wide range of filling (5 – 65 wt%). It was shown that the filling significantly changes the appearance and viscosity (especially at 50-65 wt%), but has little effect on the curing kinetics of the composites. The obtained polymer composites are characterized by increased or acceptable physical, mechanical, and chemical-resistant properties. At the same time, the mechanical properties of the filled composites can be preserved or even enhanced after severe thermal heating (250-300 °C), which is not typical for unfilled polyepoxides (which degrades and weakens its properties at 250-300 °C). These properties open up new possibilities for using cheaper epoxy materials for work in extreme areas of service, industry, and technology.
