Abstract

The invention discloses a metal surface heat preservation and insulation coating and a preparation method and an application method thereof. The metal surface heat preservation and insulation coating comprises PVDF resin, a water-borne epoxy resin solution, hollow glass beads, ytterbium modified nano powder, a diluent, polyvinyl alcohol, titanium dioxide powder, 2-10 parts of rare earth, negative ion powder and a flatting agent. The PVDF resin, the water-borne epoxy resin solution and the polyvinyl alcohol are added to synergistically form a film, the preparation raw materials are mixed more uniformly, the leveling property of the coating is higher, the coating has a good heat preservation and heat insulation effect, and the rare earth is synergistically compounded with the hollow glass beads, the ytterbium-modified nano powder, the titanium dioxide powder and / or the zirconia ceramic powder, the heat insulation performance and the high temperature resistance of the coating are significantly enhanced, the coating can be prepared into a heat-insulating coating, a heat-insulating agent and the like, can be applied to the metal surface, improves the heat preservation and heat insulation property of the metal surface, is beneficial to improving the environment quality by selectively adding the anion powder, has diversified functions and has a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation coatings, and in particular relates to a thermal insulation coating for metal surfaces, a preparation method and an application method. Background technique [0002] In recent years, with the rapid development of my country's economy, people's requirements for living comfort are constantly increasing. In summer, the energy of thermal radiation under sunlight will accumulate on the surface of the building, causing the external temperature to rise continuously, and the heat will be continuously transmitted to the interior of the building, seriously affecting the comfort of people's lives. At the same time, increasing the air conditioner, electric fan, Electricity consumption of refrigeration facilities such as refrigerators. The extensive use of air conditioners in summer has made building energy consumption one of the main areas of energy consumption in my country. Therefore, how to re...
