Abstract

The invention discloses a nano ATO (antimony oxide) / CuS (copper sulfide) filler type waterborne acrylic acid transparent thermal insulation coating. A preparation method of the coating comprises preparation of CuS nanoparticles, preparation of CuS slurry, preparation of ATO slurry and preparation of the nano ATO / CuS filler type waterborne acrylic acid transparent thermal insulation coating. The CuS nanoparticles and the ATO nanoparticles are taken as inorganic filler and added to a waterborne coating, and the thermal insulation performance of the coating is greatly improved. Compared with the 5-6 DEG C temperature difference effect of a conventional nano ATO filler type waterborne acrylic acid transparent thermal insulation coating, the temperature difference of the nano ATO / CuS filler type waterborne acrylic acid transparent thermal insulation coating can reach 11 DEG C. The method is simple in preparation, a process is convenient to operate, and the cost is low; through improvement, the energy loss can be reduced, and the coating has huge application value and prospect in thermal-insulation glass coatings and has a good prompting effect on low-energy-consumption city development.

Description

technical field [0001] The invention relates to a nano-ATO / CuS filler water-based acrylic transparent heat-insulating paint, which belongs to the technical field of water-based acrylic transparent heat-insulating paint. Background technique [0002] Energy saving is a new theme in today's society. As one of the three major tests (resources, energy, and environment) that restrict my country's economic development, energy consumption has attracted more and more attention. Among them, building energy consumption occupies a large proportion of energy consumption, accounting for about 30% of total energy consumption, most of which come from the loss caused by heating and air conditioning, which can account for more than 20%. China's annual new building area is nearly 4.5 billion square meters, of which more than 99% are high energy consumption buildings, and the environmental protection and energy saving of buildings are imminent. Therefore, building energy-saving potential is ...
