Problems solved by technology

Although this kind of thick-walled hollow microspheres can enhance the hardness, scrubbing resistance and wear resistance of the coating, but when used in thermal insulation coatings, the thermal insulation effect is not very ideal, so the paint film generally needs to be more than 3mm. Provide better heat insulation effect; moreover, pure white paint cannot be produced by using this kind of hollow microspheres. Even after the paint is toned, the color tone is too dark, so it is not suitable for use as a heat insulation topcoat for building interior walls

Abstract

The invention discloses a kind of thin thermal insulating inner wall paint. The comprised components and their weight proportion are as follows: styrene-acrylic emulsion 28- 35%, titanium dioxide 8- 13%, fillings 10- 18%, borosilicate hollow microsphere 6- 12%, water- brone nanometer anti- pollution agent 0.5- 2%, defoaming agent 0.3- 0.5%. Said hollow microsphere is hollow white spherical powder with thin wall, the main component is silicon dioxide and diboron trioxide, the real density is small and heat conductive coefficient is 0.04- 0.08 w / m.k. The invention aslo discloses the preparation and construction method for said paint. It employs high pressure airless painting process for construction, the aperture of employed gunjet nozzle is 0.6- 0.8 mm, atomization pressure is 15- 18 Mpa, and when the coating layer is 0.3- 1.0 mm, the coating layer is homogeneous and tight, and the thermal insulating effect is good. The paint is especially suitable for building inner wall and ceiling painting.

Description

Technical field: [0001] The invention relates to the technical field of architectural coatings, in particular to a thin thermal insulation coating used for coating interior walls, ceilings and other parts of buildings, as well as a preparation method and a construction method thereof. Background technique: [0002] At present, the application market of my country's thermal insulation materials in the construction industry has not really formed. There are mainly the following reasons. A protective layer needs to be added before it can be used, so construction, installation, disassembly, and repair are extremely inconvenient; secondly, the raw materials of thermal insulation materials commonly used today are various, and the production process is complicated; moreover, the widely used silicic acid Salt thermal insulation coatings generally dry slowly and require thick coatings, and the weather resistance and decorative properties still need to be further improved. They often nee...
