Exterior wall stone-like thermal insulation coating and preparation method thereof

Abstract

The present application relates to the technical field of ink curing coating, and discloses a preparation method of external wall stone-like thermal insulation coating, which is composed of the following components in mass fraction: 30-50 parts of acrylic emulsion, 8-20 parts of glass powder, 5-15 parts of ceramic powder, 15-30 parts of natural stone powder, 10-25 parts of sand, 0.3-1.2 parts of thickening agent, 0.5-1.5 parts of wetting dispersant, 1.5-3.5 parts of film-forming aid, 1-5 parts of mildew-resistant weathering agent and 50-80 parts of water. The external wall stone-like thermal insulation coating of the present application forms a micro heat insulation layer in the coating by adding components such as glass powder and ceramic powder, effectively reduces heat conduction, reduces the energy consumption of buildings, and achieves good thermal insulation effect. The mildew-resistant weathering agent used is a new compound, which can achieve long-term bacteriostasis by destroying the cell wall of mold or interfering with its metabolic enzyme system. It has high stability and is not easy to decompose in a humid environment, and can provide long-lasting mildew protection for buildings.
