Description

Technical Field

[0001] The utility model relates to the field of coating structures, in particular to a structure of a heat-insulating coating. Background Art

[0002] A heat-insulating coating is a functional coating applied to the surface of an object, aiming to reduce heat transfer, lower the surface temperature of the object, improve energy efficiency and protect the object from the influence of high temperature.

[0003] In the prior art, during the use of the heat-insulating coating, due to the poor heat-insulating effect of the coating itself, heat is easily transferred quickly, resulting in serious overheating of the base material, affecting the normal use of the base material, and easily causing the coating itself to peel off, reducing its own service life. Content of the Utility Model

[0004] The utility model mainly provides a structure of a heat-insulating coating that is convenient for improving the heat-insulating effect and service life.

The coating structure includes a primer layer. A first transition layer is adhesively provided on the surface of the primer layer. A heat-insulating layer is sprayed on the surface of the first transition layer. A second transition layer is adhesively provided on the surface of the heat-insulating layer. A reflective layer is adhered on the surface of the second transition layer. The base layer is made of a glass fiber reinforced composite material, which is beneficial to improving the adhesion between the coating structure and the base material. The primer layer is provided on the surface of the base layer and is made of an epoxy resin material, which is beneficial to improving the adhesion to the base layer. The first transition layer is beneficial to play a buffering role, avoiding the thermal stress generated during temperature change from damaging the coating structure, and improving the stability and durability of the coating structure. The heat-insulating layer is beneficial to play an effective heat-insulating role, effectively avoiding heat transfer. The second transition layer is beneficial to making the heat encounter more obstacles during the transfer process, thereby significantly improving the overall heat-insulating effect. At the same time, the second transition layer is beneficial to dispersing heat. The reflective layer is made of an aluminized polyester film, reflecting most of the external thermal radiation back, reducing heat absorption, and thus reducing the direct effect of heat on other layers of the heat-insulating coating.

[0006] Preferably, a topcoat layer is coated on the surface of the reflective layer. A base layer is provided at the bottom of the primer layer. The topcoat layer is made of a fluorocarbon resin material, which has excellent weather resistance and ultraviolet resistance, is beneficial to maintaining color and luster for a long time, plays a good protective role for the coating structure, and extends its service life.

[0007] Preferably, the bottom of the base layer is connected to the base material. The base layer is in direct contact with the coated base material, which is beneficial to providing basic adhesion and support.

[0008] Preferably, the thickness of the second transition layer is 0.3-0.8 mm. The second transition layer is made of a ceramic film material, which can reflect part of the thermal radiation, provide good thermal resistance, and thus improve the heat insulation performance.

[0009] Preferably, the thickness of the heat insulation layer is 0.5-3 mm. The heat insulation layer is made of asbestos material, which has good heat insulation performance and improves the heat insulation performance of the coating structure.

[0010] Preferably, the thickness of the first transition layer is 0.3-0.8 mm. The first transition layer is made of an aerogel composite material, which is beneficial to effectively block heat transfer, improve the heat insulation performance, and reduce the non-uniformity of thermal stress and heat transfer.

At the same time, the second transition layer is beneficial to disperse heat, and the reflective layer reflects most of the external thermal radiation back, reducing heat absorption, and thus reducing the direct effect of heat on other layers of the heat insulation coating.
