Abstract

The invention provides energy-saving and durable self-cleaning variable-color outer wall water paint and a preparation method thereof. The outer wall water paint is prepared from a modified acrylic emulsion, pigment filler, functional filler, variable-color pigment, an assistant and water, wherein the modified acrylic emulsion is prepared by polymerizing 8-14 parts of fluorinated acrylate monomer, 10-20 parts of alkenyl silane and 75-85 parts of acrylate monomer, all by mass; the pigment filler is a mixture of titanium dioxide, talc powder and sodium thiosulfate; the functional filler is rice husk ash; the variable-color pigment is sheet mica coated with a titanium dioxide nanofilm. The outer wall water paint has the advantages of strong hardness, adhesion and covering power and perfect water resistance and acid-base resistance and can be protected from color change and falling for a long time; moreover, the color of the film changes according to different viewing angles, and the film is durable and has a good aesthetic effect. Meanwhile, the coating also has relatively good stain resistance and heat insulating property and can realize self-cleaning and energy-saving effects.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an energy-saving and durable self-cleaning color-changing exterior wall water paint and a preparation method thereof. Background technique [0002] Applying paint on the walls of buildings, especially color-changing paint, can beautify the environment and the living room, but the traditional paint will be contaminated by pollutants after a period of time, and the color will change and fall off, especially now that the problem of smog is becoming more and more serious. Coatings are even more susceptible to contamination. Moreover, some exterior wall coatings have obvious heat-absorbing and heat-releasing effects, which can easily cause the problem of the house being cool in winter and warm in summer, requiring more energy to maintain the temperature of the house. [0003] Various self-cleaning coatings have been reported in existing patents. For example, the Chinese invention patent "a s...
