Problems solved by technology

In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating; while profile-based inorganic thermal insulation materials need to be assembled and constructed, there are many seams, which damage the appearance and waterproof. Defects such as poor performance and short service life
[0003] Now there are also heat-insulating coatings for heat insulation. This kind of heat-insulating coating has the problems of single function, limited effect and short validity period, and the construction method is complicated. It is mostly used in industry, but rarely used in construction projects and residential construction.
But now there is no heat-insulating coating that can be fully applied to architectural engineering and residential construction.

Abstract

The embodiment of the invention provides a reflective heat-insulation coating and a preparation method thereof. The reflective heat-insulation coating comprises the following raw materials of aqueous pure crylic acid resin, aqueous elastic resin, titanium dioxide, ceramic hollow microspheres, infrared powder, a flame retardant, water, an organic dispersant, a film-forming additive, an antifreeze, a thickener, an anti-foaming agent, a wetting agent, a preservative and a pH value regulator. The coating is a single-component aqueous coating, has no toxicity and good weatherability; extremely fine hollow microsheres are closely arranged by multi-stage in the coating to form a vacuum layer so as to have extremely strong reflection and obstruction function to the solar radiation heat and can effectively reduce the radiation heat transfer and convection heat transfer, thus reducing the heat balance temperature on the surface of the article. The reflective heat-insulation coating leads the building space and the facility container to be warm in winter and cool in summer, reduces the heat island effect and energy consumption of the air conditioner, has obvious energy-saving effect, and reduces the surface temperature by 20 DEG C to a maximum extent and reduces the internal temperature by 5-10 DEG C compared to the normal coating.

Description

technical field [0001] The invention relates to architectural coatings, in particular to a reflective heat-insulating coating and a preparation method thereof. Background technique [0002] Building energy consumption accounts for 30-40% of the total energy consumption of human beings, most of which are heating and air-conditioning energy consumption, so thermal insulation technology is more and more applied to buildings, such as various wall Insulation materials, reflective insulation coatings, etc. The traditional thermal insulation materials are mainly to increase the gas phase void ratio and reduce the thermal conductivity and conductivity coefficient. In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating; while profile-based inorganic thermal insulation materials need to be assembled and constructed, there are many seams, which damage the appearance and wate...
