Abstract

The invention belongs to the field of paint and specifically discloses a preparation method of anti-ageing external wall nano-paint. The preparation method comprises the following steps: (1) preparation of a spiral mesoporous titanium dioxide nanotube: firstly, preparing a precursor solution of mesoporous TiO2; after carrying out electrostatic spinning on the precursor solution, taking out the precursor solution and then putting into a muffle furnace; keeping the heat and roasting to obtain the spiral mesoporous titanium dioxide nanotube; (2) dispersing the spiral mesoporous TiO2 nanotube into water, and adding propylene glycol, a film-forming auxiliary agent, a wetting agent, a preservative, hydroxyethylcellulose and a dispersant; after uniformly stirring in a stirrer, conveying a mixture into a grinding machine; then adding titanium dioxide, calcium triple superphosphate, kaolin and talcum powder; after sufficiently grinding, adding polyacrylic emulsion, a de-foaming agent and a thickening agent and uniformly mixing; and filtering to obtain a final nano-paint product. The external wall nano-paint disclosed by the invention has a good anti-ageing performance.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a preparation method of anti-aging exterior wall nano coatings. Background technique [0002] Paint is traditionally called paint in China, and it is a commonly used surface decoration material. It has a wide range of applications in the fields of vehicles, decoration, military, transportation, construction, etc. Among them, architectural coatings are the most commonly used building materials, accounting for most of the market share in the entire coatings market. Paint and paint are the same concept. Paint is a customary name that people have used for a long time. After it was introduced into my country, it has been used in the construction industry. Traditional paints are usually composed of film-forming substances, pigments and fillers, solvents, additives, etc. [0003] Driven by the construction industry, China's coatings industry is growing from strength to strength. Statistics s...
