Abstract

The invention belongs to an energy-saving type building outer wall coating and a preparation method thereof, and relates to the field of coating production. The prepared coating comprises 40-60 parts of polymer emulsion, 10-30 parts of titanium dioxide nano powder, 10-30 parts of padding, one to five parts of coalescing agents, one to five parts of hydrophobic promoters, five to 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, six to nine 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 promoters, the padding and the solvents are mixed and react, suspension liquid is removed through filter to obtain the modified padding, after the modified padding, the polymer emulsion, the titanium dioxide nano powder, the dispersing agents, the antifoaming agents, the wetting agents and the water are evenly mixed according to the proportion, polymer powder, the putty and modified floating beads are added to be stirred evenly, and the energy-saving type building outer wall coating is prepared. Waterproofness and soiling resistance of the produced coating can be improved, the weather fastness and heat insulation property of the coating are improved, and energy saving and environmental protection are achieved.

Description

technical field [0001] The invention relates to the field of paint production, in particular to the production of energy-saving building exterior wall paint. Background technique [0002] Bricks, mosaics, glass curtain walls and coatings are often used for beautification and decoration on the exterior walls of buildings. Because paint is easy to be contaminated with oil in the air and easy to leave water stains after being eroded by wind and rain, which greatly affects the aesthetic feeling of buildings, facing bricks, mosaics and glass curtain walls occupy the main market of existing building exterior wall decorations . However, the use of exterior wall decorations such as facing bricks, mosaics, and glass curtain walls in high-rise buildings will cause potential safety hazards. The market has an urgent demand for coatings with waterproof and oil-proof properties. [0003] CN 102732079 A (2012.10.17) discloses a preparation method of exterior wall paint, and the stain res...
