Abstract

The invention discloses a water-based high-covering roller painting white primer and a preparation method thereof. The primer contains a component A which is a water-based isocyanate curing agent; and a component B which comprises the following components in parts by weight: 40-50 parts of water-based hydroxyl polyacrylate; 20-22 parts of a water-based emulsion; 5-7 parts of titanium dioxide; 15-18 parts of talcum powder; 5-7 parts of calcium carbonate; 1.3-1.6 parts of a dispersant; 2.1-2.6 parts of a preservative; and 1.6-1.8 parts of a defoaming agent. According to the invention, the acrylic emulsion and the polymerized covering emulsion with high pigment and filler wrapping capacity are adopted to bind loose pigment and filler particles, so that the coating film has good compactness, and the coating area is increased; and the paint has good leveling property, compactness and high covering power.
