Problems solved by technology

[0006] Some people use cold pigments (that is, special ceramic pigments) to make heat-reflective coatings, which can also meet the above requirements, but the price of cold pigments is very expensive, and the price of one kilogram can easily cost hundreds of yuan. At the same time, the color of cold pigments is generally darker. , it is difficult to bring out bright colors, and it is difficult to promote in the civil architectural coatings industry. How to use our common pigments or some cheap and high-quality thermal insulation pigments and fillers to reduce the unit price of thermal insulation coatings and meet the standard requirements at the same time It is the significance of the invention of this patent

Description

Technical field [0001] The invention relates to a paint, in particular to a full-color reflective heat-insulating paint system for buildings and a preparation method thereof. Background technique [0002] Energy conservation and emission reduction have become an important task for all walks of life. At present, building energy consumption accounts for 30% of the energy consumption of the whole society. It is a long way to promote building energy conservation. [0003] With the society's demand for intensive development and the aggravation of the global greenhouse effect, materials with the ability to reflect solar heat and passive radiant cooling have attracted increasing attention. Among them, heat-reflective coating is a kind of energy-saving material that is simple and easy to implement and has obvious effects. [0004] Since the introduction of heat insulation in our country, many manufacturers have produced various concepts of heat-insulating heat-reflective coatings. The count...
