Problems solved by technology

However, the density of round sand is high, adding it to the paint and spraying it on the outer wall will increase the weight of the building, and there is a danger of falling off the wall due to wind and sun, and it will also affect the dispersion of the paint.

Abstract

The invention discloses a sepiolite-fiber-added compound waterborne coating for an outer wall. The coating is characterized by being made from the following raw materials, by weight part, 26-29 of a VAE emulsion, 11-14 of a wax emulsion, 1-2 of an aziridine cross-linking agent, 3-4 of calcium-magnesium powder, 1-2 of sodium diethyl succinate sulfonate, 8-10 of maifan stone, 2-4 of fluorinated graphite, 3-4 of ceramic cellucotton, 3-5 of sepiolite fibers, 0.3-0.5 of sodium fluoride, 6-8 of modified round-grained mortar and 25-30 of water. The formula is scientific and reasonable; through cooperation of the VAE emulsion with the aziridine cross-linking agent, the viscosity and water resistance of the coating is improved; through addition of sepiolite fibers, the coating has an excellent absorption effect and high temperature resistance and the coating film is not prone to crack; and through addition of the modified round-grained mortar which is light in weight and good in dispersion, the brightness, viscosity and strength of the coating is improved. The coating can meet different decoration requirements.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a composite water-based coating with sepiolite wool added for exterior walls and a preparation method thereof. Background technique [0002] Sepiolite wool is a new generation product to replace asbestos. Sepiolite is a non-metallic mineral, white in appearance, like a row of white wool bonded together, non-toxic. High temperature resistance, heat preservation, strong adsorption capacity, decolorization ability, high thermal stability, high temperature resistance, good shape, low shrinkage rate, not easy to crack, and high salinity resistance, corrosion resistance, and special properties of radiation resistance. Widely used in thermal insulation materials, etc. [0003] Round grain sand is made by crushing and rounding natural quartz, with high Mohs hardness, round particles without sharp corners and flake particles, high purity without impurities, high silicon cont...
