The materials comprise the following components in parts by weight: 35 to 50 parts of water-based fluorocarbon emulsion, 5 to 15 parts of light polymer hollow microspheres, 5 to 10 parts of hollow glass microspheres, 5 to 10 parts of nanoscale ATO slurry, 5 to 15 parts of nanoscale metal powder, 3 to 8 parts of nanoscale titanium dioxide, 0.2 to 0.5 parts of dispersant, 0.4 to 0.8 parts of thickening agent, 0.2 to 0.4 parts of anti-mildew and bactericidal agent, 0.5 to 2.5 parts of film coalescing aid, 0.6 to 1.6 parts of silane coupling agent and 15 to 25 parts of deionized water. The coating disclosed by the invention can effectively reflect thermal energy conduction, block thermal radiation and stop infrared thermal energy, the thermal insulation property is excellent, energy consumption is low, the thermal insulation effect is remarkable, the service life is long,the preparation method is simple, and the invention is suitable for mass production and application.

Description

technical field [0001] The invention relates to the technical field of nano heat-insulating functional new materials, in particular to a water-based nano-composite heat-insulating coating and a preparation method thereof. Background technique [0002] With the development of my country's construction industry, the importance of energy saving in houses has become increasingly prominent. Ordinary exterior wall coatings will absorb the infrared rays in sunlight and convert them into heat energy, causing the temperature of the coating to rise. raised. Theoretically speaking, as long as the heat radiation can be effectively reflected or blocked, the effect of heat insulation can be effectively achieved, such as the use of silicate materials. Classic wall thermal insulation materials include phenolic resin synthetic materials, polyurethane materials, glass fiber materials, aluminum silicate rock wool, mineral wool, rubber and plastic, cork, perlite, etc. These materials have th...
