Abstract

The invention relates to the technical field of interior wall surface paint, in particular to outdoor heavy-duty anti-corrosion self-cleaning water paint and a using method thereof. The water paint includes a component A and a component B, wherein the component A includes: 15-75 parts of aqueous polyurethane, 0.5-10 parts of a defoamer, 0.5-10 parts of a leveling agent, 1-20 parts of a coupling agent, 5-40 parts of color paste, an anti-ultraviolet agent and a water repellent, and the component B includes an aqueous curing agent. The outdoor heavy-duty anticorrosive self-cleaning water paint isprepared by the following steps: sequentially adding the components into a high-speed stirrer, adding water, stirring the components, mixing the components with the water-based curing agent, and curing the mixture.

Description

technical field [0001] The invention relates to outdoor anticorrosion self-cleaning water The technical field of paint, in particular to an outdoor heavy-duty anti-corrosion water paint and its application method. Background technique [0002] Generally speaking, the quality of the paint is determined by the composition and structure of the paint. The type and quality of film-forming substances and pigments are important factors affecting the structure of coatings. As an exterior wall coating, aging resistance is more critical. The so-called aging is mainly the degradation of high polymers as film-forming substances. The main aging method of exterior wall coatings is photo-oxidative degradation under the action of water, so it is necessary to choose appropriate additives, and use reasonable raw materials and scientific formulations. Ratio and advanced production technology to get high-quality coatings. However, the existing anti-rust and anti-corrosion paints all have th...
