Abstract

The invention relates to water-repellent breathable type stone-like paint. The water-repellent breathable type stone-like paint is prepared from, by weight, water, non-ionic water-soluble cellulose ether, 2-amino-2-methyl-1-propanol aqueous solution with the mass concentration of 90-95%, a dispersing agent, a wetting agent, colloid silicon dioxide, pure acrylate emulsion, a film coalescing agent, cosolvent, a defoaming agent, sterilization preservative, a rheological additive and aggregate. The water-repellent breathable type stone-like paint overcomes the disadvantages that existing stone-like paint is prone to becoming water white and soft after being exposed to the rain and empty drums and blisters are likely to appear in external wall stone-like paint veneer coatings, and has the advantages of excellent water-repellent performance and high breathability.

Description

technical field [0001] The invention relates to a water-repellent and air-permeable real stone paint and a preparation method thereof, which are applied in the field of architectural decoration paints. Background technique [0002] In recent years, thanks to the improvement of people's health and environmental protection concept and the progress of coating technology such as emulsion synthesis, real stone texture coatings have occupied a large market share in the field of exterior wall decoration and protection, gradually replacing stone, ceramic tiles, aluminum-plastic composite panels and other exterior walls. decoration material. Compared with stone, real stone paint has many advantages such as light weight, cheap price, environmental protection and health, and convenient construction. [0003] However, compared with the stone surface, real stone paint is relatively loose, and it is prone to water whitening, softness and other paint film defects after being exposed to ra...
