Embodiment 7

[0057]Example 7: Performance test

[0058]1. Preparation of test sample

[0059]In order to better simulate actual application conditions, this embodiment uses the "anticorrosive primer layer + reflective thermal insulation coating" heat insulation system for performance testing. The test sample is 3mm sandblasted steel plate, and the anticorrosion primer is ZD800 (W) water-based Epoxy zinc-rich primer (Tianjin Shuangshi Paint Co., Ltd.), according to different test requirements, scratched reflective heat insulation coating, performance test, including salt spray resistance, sunlight reflection ability test matching reflective heat insulation coating The layer thickness is 1.0 mm.

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

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

[0062]Step 2: After spraying the anticorrosive primer for 24 hours or afte...

Abstract

The invention provides a water-based reflective thermal insulation coating and a preparation method and application thereof. The water-based reflective thermal insulation coating is prepared from, byweight, 30-45 parts of fluorosilicone emulsion, 20-35 parts of silicone acrylic emulsion, 9-18 parts of filler, 15-25 parts of nano titanium dioxide, 0.2-3 part of water-based floating aluminum paste,0.2-3 part of water-based non-floating aluminum paste, 0.9-4.5 part of coalescing agent, and 0.1-0.8 part of a bacteriostatic agent.

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]In the scorching summer sun, the atmospheric temperature is generally above 30℃. When the outer surface of cement, concrete, ceramic tiles, metal, insulation bricks, glass and other building materials are exposed to long-term sun exposure, their temperature can reach 40-50℃ , And when the color steel plate, waterproof material, etc. are exposed to the sun for a long time, the temperature can even reach the hot temperature of 60-70℃. The foregoing situation has adversely affected normal human habitation, material storage, and equipment safety.[0003]It is known in the art that the use of reflective thermal insulation coatings on the surface of a building can effectively reduce the temperature of the surface and the interior of the building, and can alleviate the temperature chan...
