Embodiment 1

[0033] The specific preparation method and steps of the present embodiment are as follows:

[0034] (1) First add 10g of dispersant polyacrylate ammonium salt, 2.5g of wetting agent, 1.5g of hydroxyethyl cellulose, and 4g of defoamer into 150ml of water, and stir and disperse with a mixer at a speed of 500rpm for 10 minutes ;

[0035] (2) Then the nano photocatalyst TiO 2-X N X Slowly add 10g of powder and disperse for 15 minutes with a mixer at 1000rpm;

[0036] (3) This time, add 40g of pigment titanium dioxide, 120g of filler heavy calcium carbonate, 50g of kaolin, and 25g of talcum powder, and stir together at 2000rpm with a high-speed mixer for 1 hour;

[0037] (4) Sand milling is then carried out, and the above-mentioned premixed and dispersed slurry is fully pulverized and fully mixed and dispersed at a speed of 2000 rpm in an agitator equipped with a grinding and dispersing head and a grinding medium tempered glass ball until the slurry particles U, A building coat...

Description

technical field [0001] The invention relates to a building coating material with the function of purifying air and a preparation method thereof, belonging to the technical field of chemical coatings. Background technique [0002] With the rapid development of modern industry and the increasing environmental pollution, people put forward higher requirements for architectural coatings, such as air purification, high weather resistance, high decoration, high stain resistance, low pollution, etc. Therefore, The development and application of high-performance multifunctional architectural coatings has become one of the important topics in the current coatings industry. Introducing nanoparticles or nanostructures into the architectural coating system and compounding them with coating resins can improve the performance of architectural coatings or endow them with new functions. This is based on the influence and function of the surface effect, small size effect, quantum size effec...
