▎ 摘  要

NOVELTY - Single component waterproofing coating composition comprises Portland cement, calcium carbonate, calcium stearate, where the composition comprises graphite, mixture of natural resins based on water, thickener, polymeric dispersant, antifoam based on mineral oils, and a laboratory formulation. USE - The composition is useful in the field of surface coatings. ADVANTAGE - The composition: has hydrophobic and waterproofing properties; improves mechanical properties e.g. flexibility, tensile strength and high level of thermal conduction; has resisting high temperatures; provides oxidation resistance; and allows the coating to expand without causing cracks in the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing the single component waterproofing coating comprising producing the laboratory formulation of Portland cement, calcium stearate and graphite separately, where the mixture of these components is heated of 70-150° C, properly homogenized in a crusher and making a second mixture after the previously produced laboratory formulation, while heating at a temperature of 70-170° C, where the composition comprises Portland cement, calcium carbonate, calcium stearate, mixture of natural resins based on water, thickener, polymeric dispersant, antifoam based on natural oils and laboratory formulation, generating the final product. DESCRIPTION OF DRAWING(S) - The figure shows the color of the coating in its wet phase, when it is still in the drying process and when it is already dry. 1Wet phase 2Drying process 3Already dry
