NOVELTY - Root-resistance environmentally friendly polymer cement waterproof coating comprises component A and component B, where the weight mixing ratio of component A to component B is 1:1-1:1.3. USE - The coating is useful for waterproof construction of planting surface in toilet bathing room, kitchen, building outer wall, waterproof construction of underground engineering and impounding reservoir. ADVANTAGE - The coating has good root resistance, environmental protection, high strength, high extension and strong base bonding. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing root-resistance environmentally friendly polymer cement waterproof coating, comprising (1) preparing component A: component A is an aqueous solution, adding high molecular polymer emulsion, root inhibitor, surfactant, anti-foaming agent, preservative, dispersant, plasticizer, thickener, anti-aging agent, high-efficiency nano-adhesive and water, stirring and mixing to obtain product, (2) preparing Component B: component B is powder, sequentially adding cement, heavy calcium carbonate, quartz powder, kaolin, precipitated barium sulfate, mica powder and graphene powder, mixing, and stirring for 2 hours at medium speed, and (3) mixing: firstly placing component A into mixing, stirrer weighing a certain weight B component according to the mixing proportion, slowly pouring the component B into component A, stirring at a speed of 600 revolutions/minute for 10-15 minutes, reducing the speed to 300 revolutions/minute, and stirring for 5-10 minutes until there are no obvious bubbles in the coating.
