Embodiment 1

[0049] Example 1 Water-based reflective insulation coating

[0050] In this example, the prepared water-based reflective heat-insulating coating is made of the following components in parts by weight: 30 parts of fluorosilicon emulsion, 35 parts of silicon acrylic emulsion, 3 parts of hollow ceramic microspheres, 3 parts of phase change particles 3 parts of nano-airgel powder, 20 parts of nano-titanium dioxide, 0.35 parts of water-based floating aluminum-silver paste, 0.35 parts of water-based non-leafing aluminum-silver paste, 1.5 parts of dispersant, 1.5 parts of defoamer, and 1.5 parts of rheology additive part, 0.8 part of antibacterial agent;

[0051] Its preparation method is as follows:

[0052] Put fluorosilicon emulsion, silicon acrylic emulsion, water-based floating aluminum-silver paste, water-based non-leafing aluminum-silver paste, film-forming aids, and antibacterial agents in a container, and disperse them for 14 minutes at a stirring rate of 1200r / min to obt...

Embodiment 7

[0057] Embodiment 7: performance test

[0058] 1. Preparation of test samples

[0059] In order to better simulate the actual application conditions, this example adopts the heat insulation system of "anti-corrosion primer layer + reflective heat-insulation coating" for performance testing. The test sample is a 3mm sandblasted steel plate, and the anti-corrosion primer is ZD800 (W) water-based Epoxy zinc-rich primer (Tianjin Shuangshi Paint Co., Ltd.), according to different test requirements, scrape reflective heat-insulating coating for performance testing, among which the matching reflective heat-insulating coating for salt spray resistance and sunlight reflection ability test The layer thickness was 1.0 mm.

[0060] The method of preparing the test sample of the reflective thermal insulation coating is as follows:

[0061] Step 1: Clean up the floating dust and dirt on the surface of the base surface, and spray the anti-corrosion primer after the surface is dry;

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based reflective heat-insulating coating and a preparation method and application thereof. Background technique [0002] Under the scorching sun in summer, the atmospheric temperature is generally above 30°C. When the outer surfaces of building materials such as cement, concrete, tiles, metal, insulation bricks, and glass are exposed to the sun for a long time, their temperature can reach 40-50°C. , and when the color steel plate, waterproof material, etc. are exposed to the sun for a long time, their temperature can even reach a scalding temperature of 60-70°C. The above-mentioned situation has adversely affected normal human habitation, material storage, and equipment safety. [0003] It is known in the art that the application of reflective heat-insulating coatings on building surfaces can effectively reduce the temperature of the building's surface and interior, and can allev...
