Abstract

The invention relates to an aqueous transparent heat insulation paint, which contains, by weight, 2.0-5.0 parts of a nanometer ITO compound powder, 37.5-40.5 parts of distilled water, 44-55 parts of a waterborne FEVE fluorocarbon resin emulsion and 7.5-8.5 parts of an HDI curing agent, wherein the grain size range of the ITO compound powder is 20-50nm. The preparation method provided by the invention comprises the following steps of: adding distilled water into a reaction container, adding the nanometer ITO compound powder into distilled water by high speed dispersion for 15-50 minutes until the powder becomes a paste, adding the obtained paste into the FEVE emulsion, followed by middle speed dispersion for 15-50 minutes to obtain an intermediate product, adding the HDT curing agent into the intermediate product with stirring, followed by middle speed dispersion for 15-50 minutes to obtain the product. The product provided by the invention has excellent heat insulation performance and low price, can be used for microwave attenuation and can also be used in fields such as a glass paint for buildings.

Description

technical field [0001] The invention relates to the technical field of nano coatings, in particular to a water-based nano transparent heat-insulating coating and a preparation method thereof. Background technique [0002] Since the 20th century, the world's energy consumption has increased significantly. Energy saving, reducing energy consumption, and improving economic benefits are one of the major goals of scientific research and technological development. [0003] Among all kinds of energy consumption, building heating and air conditioning energy consumption occupies a considerable proportion. Doors and windows, as transparent and openable envelopes in house construction, are the weakest part of the heat insulation in winter and summer. [0004] Among the methods to solve the heat insulation in winter and summer, some use energy-saving glass LOW-E glass, also known as low-emissivity coated glass, which has good energy-saving effect and has many applications. However, it...
