Abstract

The invention discloses a water-based reflective thermal insulation coating and a preparation method thereof, the reflective thermal insulation coating selects carbon nanotube modified epoxy resin andorganosilicon modified fluorocarbon emulsion for compounding as a film forming substance, the flexibility and frictional wear performance of a paint film are significantly enhanced, and the adhesiveforce of the paint film is improved; silicon-aluminum coated modified nano titanium dioxide is selectively added, so that the paint film is endowed with extremely high weather resistance and reflective heat-insulating property; high-hardness particles such as nano ytterbium oxide, kaolin and ground calcium carbonate are matched, so that the high-hardness particles are embedded in the compact paintfilm formed by film forming matters when the coating forms a film, and when the surface of the paint film is rubbed by the outside, the high-hardness particles bear most of friction force, so that the abrasion effect of the surface of the paint film is reduced, and the reflective heat insulation property, the abrasion resistance and the washing resistance of the paint film are comprehensively improved. According to the reflective thermal insulation coating provided by the invention, the thermal insulation temperature difference reaches 17-20 DEG C, the reflectivity reaches 90% or above, and the reflective thermal insulation coating has a relatively high practical value.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a water-based reflective heat-insulating coating and a preparation method thereof. Background technique [0002] Solar energy is a necessary condition for human survival and life, but the surface temperature is too high due to the strong radiation of the sun absorbed by the object, which will bring many problems to people's life. In hot summer, sunlight shining on the building surface will increase the internal temperature and increase the burden on the air conditioning system, thereby increasing energy consumption and carbon dioxide emissions. In recent years, color steel roofs have been widely used in the construction of large factories, office buildings, and municipal venues due to their short construction period, low requirements for load-bearing structures, and large-span construction. [0003] After the sun is irradiated, the temperature difference deformati...
