Abstract

The invention discloses a nanoneedle-structure manganese vanadate self-cleaning paint, belonging to the technical field of functional materials. The nanoneedle-structure manganese vanadate self-cleaning paint is composed of the following components in percentage by mass: 20-40% of nanoneedle-structure manganese vanadate, 15-30% of vinyl acetate-acrylic emulsion, 30-50% of water, 6-20% of nano silicon dioxide, 0.05-0.2% of alcohol ester-12, 0.5-2% of tributyl phosphate, 0.5-2% of 10% sodium hexametaphosphate water solution, 0.5-2% of ethylene glycol and 0.5-2% of polyurethane. The nanoneedle-structure manganese vanadate self-cleaning paint disclosed by the invention has the properties of self-cleaning, pollution prevention, thermal insulation, heat preservation and the like, has the advantages of stable performance and low cost, and is convenient for construction.

Description

Technical field: [0001] The invention belongs to the technical field of functional materials, and in particular relates to a nano-acicular structure manganese vanadate self-cleaning coating. Background technique: [0002] Building wall coatings can beautify the environment and living rooms, but traditional coatings will change color and fall off after a period of time, and glass curtain walls or tile veneers will cause light pollution, increase the weight of buildings, and pose safety hazards and other problems. Therefore, developing new self-cleaning coatings is an important method to solve the above problems at present. Nano-materials with photocatalytic activity, such as nano-titanium dioxide and titanium phosphate, are used as components of the coating. Under the irradiation of visible light and ultraviolet light, the nano-photocatalytic material in the coating absorbs pollutants and undergoes oxidation-reduction decomposition, thereby decomposing organic matter and orga...
