Weather-resistant reflective heat insulation coating and preparation method thereof

The invention belongs to the technical field of coatings, and in particular relates to weather-resistant reflective heat insulation coating and a preparation method thereof. The weather-resistant reflective heat insulation coating is prepared from the following components in parts by weight: 20-50 parts of emulsion, 10-40 parts of rutile type titanium dioxide, 1-20 parts of silver-plated glass flakes, 1-10 parts of infrared radiation ceramic powder and 5-30 parts of filler; the emulsion is one or a combination of more of silicone-acrylic emulsion, fluorocarbon emulsion and polyurethane emulsion; the rutile type titanium dioxide is prepared from first rutile type titanium dioxide and second rutile type titanium dioxide, and the particle size of the first rutile type titanium dioxide is smaller than that of the second rutile type titanium dioxide. By adding the silver-plated glass flakes, the sunlight reflectivity and weather resistance of the weather-resistant reflective heat insulationcoating provided by the
