Description

technical field [0001] The invention belongs to the technical field of thermal insulation coatings for buildings, and in particular relates to an energy-saving and environment-friendly thermal insulation coating and a preparation method thereof. Background technique [0002] According to the heat insulation mechanism, heat insulation coatings can be divided into three types: barrier type, radiation type and reflective type. Among them, the barrier type heat insulation coating belongs to thick traditional coatings, and its heat insulation mechanism uses low thermal conductivity to shield heat exchange; Thermal coatings emit the heat absorbed by objects into the air at a certain wavelength through the form of wave radiation, thereby achieving a cooling effect; the heat insulation mechanism of reflective thermal insulation coatings is to absorb the visible light in the sun through the reflection of the coating film. And near-infrared light is partially reflected to the outer sp...
