Abstract

The invention discloses HUPC water-based epoxy floor paint and a preparation method thereof, and belongs to the technical field of floor paint preparation. According to the invention, the UHPC super-performance concrete component, the adhesive layer material component and the aqueous epoxy floor paint component are sequentially molded from bottom to top according to the mass ratio of 150-250:0.3-1:3-10, so that the obtained HUPC aqueous epoxy floor paint has a microporous structure, allows water vapor to permeate but liquid medium cannot pass through, and releases the pressure of the water vapor in the UHPC super-performance concrete, thereby avoiding the problems of film bubbling, falling and the like, having the advantages of high strength, good adhesiveness and permeation resistance, solving the defects of easy sand-out pulverization, insufficient strength, delamination caused by false clear light and poor flatness of the existing floor paint, and having good application prospect.
