Abstract

The invention belongs to a building external wall coating and a preparing method thereof and relates to the field of coating production. The coating prepared through the method comprises 40-60 parts of polymer emulsion, 10-30 parts of titania nanonpowder, 10-30 parts of fillers, 1-5 parts of film formation auxiliaries, 1-5 parts of hydrophobic auxiliaries, 5-15 parts of solvents, 0.2-0.8 part of dispersing agents, 0.1-0.2 part of antifoaming agents, 0.1-0.2 part of wetting agents, 6-9 parts of putty and 10-20 parts of water. The polymer emulsion is a mixture of fluorocarbon emulsion and organosilicone modified acrylic emulsion. After the hydrophobic auxiliaries, the fillers and the solvents are mixed and react with one another, the mixture is filtered to remove suspension liquid so as to obtain modified fillers; then after the modified fillers, the polymer emulsion, the titania nanonpowder, the dispersing agents, the antifoaming agents, the wetting agents and the water are evenly mixed according to proportion, the putty and modified drift beads are added into the mixture to be evenly stirred, and the building external wall coating is obtained. The building external wall produced through the method can improve the waterproof and stain-resisting performance of the coating and the weather resistance of the coating.

Description

Technical field [0001] The invention involves the field of coating production and specially involves a building exterior wall coating production. Background technique [0002] The exterior walls of the building are often used for beautifying the decoration of tiles, mosaic, glass curtain walls, and coatings.Because coatings are prone to oil stain in the air and easily leave water stains after being eroded by wind and rain, it has greatly affected the beauty of the building.EssenceHowever, high -rise buildings use exterior wall decorations such as tiles, mosaics, and glass curtain walls to cause hidden safety hazards. The market has an urgent need for coatings with waterproof and oil -proof properties. [0003] CN 102732079 A (2012.10.17) The preparation method of an exterior wall coating is released. Invention content [0004] The purpose of the present invention is to overcome the problems that existing coatings cannot improve the indoor environment, and solve the above problem...
