Examination of Mechanical Properties and Temperature Resistance of Epoxy Coatings Filled with Secondary Raw Materials
Abstract:
Epoxy coatings are used mainly in the construction especially where it is necessary to increase the resistance of concrete floors against mechanical wear, to increase chemical resistance, to prevent dusting and to ensure hygienically clean environment. Epoxy coating is a composite material that consists of epoxy resin cured mainly by polyamine hardener and filler. As a filler is currently used pure silica sand Dorsilit ground to below 0.063 mm and for more demanding applications fine glass flakes with a high proportion of SiO2. The aim of this work is to experimentally examine the possibility of using secondary raw materials as fillers into three types of polymer epoxy coatings, where it seems the most appropriate utilization is waste glass with a high content of SiO2. Based on the evaluation of the test results of tensile properties, Shore hardness and temperature resistance the possibility of replacing the commonly used filler by finely ground waste glass is assessed.
