Abstract
The invention discloses a heat-shielding thermal-insulation paint, belonging to the technical field of paints. The heat-shielding thermal-insulation paint is prepared from 30-50 parts of water-soluble polyamide resin, 15-20 parts of nano organosilicon emulsion, 15-30 parts of water-based epoxy emulsion, 10-15 parts of silicon dioxide aerogel particle, 10-15 parts of nano hollow ceramic microsphere, 5-8 parts of dispersing agent, 2-4 parts of thickener, 0.5-2 parts of film-forming assistant, 8-12 parts of titanium white and 15-30 parts of water. Compared with the prior art, the silicon dioxide aerogel particle and nano hollow ceramic microsphere are added into the paint as the thermal-insulation heat-shielding materials, so that the heat conductivity coefficient of the paint is lowered by 60% as compared with that of the common pure latex paint, and thus, the paint has favorable heat shielding and thermal insulation effects. The nano hollow ceramic microsphere is adopted to enhance the wear resistance of the paint surface.
