Abstract

The invention discloses a self-cleaning water-based paint, which is prepared from the following raw materials in parts by weight: 50-60 parts of silicone acrylic emulsion, 9-12 parts of perfluorosiloxane resin, 3-4 parts of antibacterial agent, 2-3 parts of hydroxyethyl cellulose, 0.5-0.7 part of modified nano titanium dioxide, 0.8-1 part of assistant and 30-40 parts of pure water. The invention also discloses a processing method of the self-cleaning water-based paint. According to the invention, the silicone acrylic emulsion is used as a film-forming matrix of the coating, so that the coatingmatrix has the characteristics of weather resistance, hydrophobicity, low surface energy, being not liable to be polluted and the like; furthermore, by adding the modified nano titanium dioxide intothe paint, the nano titanium dioxide can be more uniformly dispersed in the paint after being modified, and the self-cleaning and photocatalysis properties are continuously and stably exerted, so thatthe coating has favorable self-cleaning properties. The water-based paint is obtained by taking water as a solvent, meets the green and environment-friendly requirements, and is suitable for buildingexterior walls.

Description

technical field [0001] The invention belongs to the technical field of water-based paint, and in particular relates to a self-cleaning water-based paint and a processing method thereof. Background technique [0002] Solvent-based coatings are an important source of VOC, which cause great pollution to the environment and great harm to the human body. At the same time, there are safety hazards such as flammability and explosion in construction, storage, and transportation. Water-based paint has the characteristics of green, energy saving, safety and convenient function, and has been developed rapidly in all countries in the world. Building exterior wall coatings can beautify the environment and the living room, but due to the poor scrub resistance of traditional coatings, the coating will change color and fall off after a short period of time, and the glass curtain wall or tile veneer will bring light pollution, increase the weight of the building, and ensure safety. hidden d...
