Abstract: Epoxy resin floor paint materials were prepared by adding quartz sand tailing and silica white into the solvent .The ratio of curing agent , quartz sand tailing and silica white were adjusted properly , which could improve the hardness and other comprehensive properties of the epoxy resin floor paint materials.Experimental results exhibited that the hardness and scrubbing times of epoxy resin floor materials can reach up to 3H and 7800 times, and the water resistance time was increased to 13 d h, and the alkali resistance time was enhanced to 7 d, when the content of quartz sand tailing , silica white and the waterborne epoxy were 1.2 g, 1.6 g and 14 mL respectively, by using T-31 as the epoxy hardener . The results are in accordance with the high class of GB/T 22374-2008.Obviously, the abrasion resistance and added value of epoxy resin floor materials have been improved , which is expected to be widely promoted for industrialization .
