Problems solved by technology

However, this material is expensive and difficult to be popularized
In addition, some coatings added with hollow microspheres and nanoparticles, although their thermal conductivity is small, have good reflectivity for ultraviolet and near-infrared rays, and have good heat insulation, but due to the opacity of the hollow microspheres themselves, The light transmission performance of the coating cannot be satisfied

Abstract

The invention discloses a transparent heat insulation coating with nanoparticles and a preparation method thereof; the preparation method comprises the following steps: adding nanoscale powder slurry of aluminum oxide, silicon oxide, titanium oxide, zinc oxide, cerium oxide, iron oxide, ATO and the like in water-based acrylic emulsion, adjusting the pH value to 5.5-9.0, stirring with a machine for 30-60min while adding defoaming agent, dispersant and flatting agent, then stirring with a high speed stirrer for 20-40min and finally performing ultrasonic vibration for 30-60min to obtain the transparent heat insulation coating. The invention has low cost and simple production process, after the coating is coated to form a film, the film has good transmission of light and outstanding heat-shielding performance; the coating has better self-cleaning ability, good durability and good washing resistance and brushing resistance; and the film has long life, good stability and simple maintenance.

Description

technical field [0001] The invention relates to a transparent heat-insulating paint containing nanoparticles and a preparation method thereof. After the paint is applied on the glass to form a film, it can ensure good light transmission and has excellent heat insulation performance; it is a new material for environmental protection and energy saving. Background technique [0002] In recent years, with the rapid development of my country's economy, urban construction is changing with each passing day, and new buildings are rising every day. Under the thermal radiation of sunlight, the temperature of glass windows and transparent ceilings of buildings will gradually rise, which will increase the utilization rate of air conditioners and increase energy consumption. According to statistics from the U.S. Department of Energy, 30% to 50% of the cooling energy of air conditioners is consumed by solar energy passing through windows. In addition, the ultraviolet rays in the sun wil...
