Description

Technical Field

[0001] The utility model relates to the field of thermal insulation paint, in particular to a thermal insulation paint structure. Background Art

[0002] Due to the continuous rise in ambient temperature and energy consumption, thermal insulation and energy saving have become a social issue of concern. External wall insulation materials are still mainly panels, which are installed by pasting, splicing, anchoring, dry hanging, etc., with low installation efficiency; and there are thermal bridges at the locations where the external wall insulation panels are spliced ​​and anchored, which reduces the insulation effect to a certain extent.

[0003] Therefore, in order to solve the deficiencies in the prior art, it is necessary to design a thermal insulation paint structure with a simple structure and good thermal insulation. Utility Model Content

[0004] The utility model provides a thermal insulation paint structure to solve the problems of the prior art.

[0005] The purpose of the utility model can be achieved through the following technical scheme: a thermal insulation paint structure includes: a base layer, a vacuum microporous insulation layer, a ceramic fiber support layer, a reflective layer and a thermal conversion topcoat layer, the vacuum microporous insulation layer is coated on the outside of the base layer, the ceramic fiber support layer is coated on the outside of the vacuum microporous insulation layer, the reflective layer is coated on the outside of the ceramic fiber support layer, the thermal conversion topcoat layer is coated on the outside of the reflective layer, and the thermal conversion topcoat layer is an acrylonitrile expansion powder layer.

[0006] As a further improvement, grooves are provided at intervals in the reflective layer.

[0007] As a further improvement, the reflective layer is a composite silica aerogel layer.

[0008] As a further improvement, hollow microbeads are provided inside the vacuum microporous heat insulation layer.

[0009] As a further improvement, the base layer is a silicone-based resin layer.

[0010] Compared with the prior art, the thermal insulation paint structure of the utility model has the following beneficial effects:

[0011] The vacuum microporous insulation layer provides low thermal conductivity, heat resistance and heat insulation, while the reflective layer gives the coating a higher infrared reflectivity, which can efficiently reflect infrared radiation; the ceramic fiber support layer and the vacuum microporous insulation layer with low thermal conductivity constitute an efficient heat shielding layer. The contact heat transfer between the reflective layers needs to pass through the reflective layer, the reflective layer and the ceramic fiber support layer, the ceramic fiber support layer and the vacuum microporous insulation layer, and the base layer and the auxiliary materials. Therefore, the contact thermal resistance is very large, which can efficiently achieve thermal insulation control.

[0012] The thermal conversion topcoat layer of acrylonitrile expansion powder serves as the outermost structure, which converts the heat reflected by the reflective layer and the inside into radiation energy and releases it into the atmosphere. The thermal conversion topcoat layer does not store heat, which greatly improves the thermal insulation effect of the coating. The coating is not easily contaminated, which extends its service life. It is directly applied to the exterior wall surface with high operating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is combined with the embodiments and attached Figure 1 , the technical solution of the utility model is further elaborated.

[0018] Example 1

[0020] As a further preferred embodiment, grooves 41 are provided in the reflective layer 4. The grooves 41 in the reflective layer 4 can increase the contact area between the reflective layer 4 and the thermal conversion topcoat layer 5, further increase the heat dissipation area of ​​the thermal conversion topcoat layer 5, and thus improve the heat dissipation effect.

[0021] As a further preferred embodiment, the reflective layer 4 is a composite silica aerogel layer. The reflective layer 4 of the composite silica aerogel can reflect infrared light in the visible light, and coupled with the structural characteristics of the aerogel, on the basis of reducing heat absorption, it cooperates with the inner vacuum microporous insulation layer 2 to further improve the heat insulation performance, thereby achieving a better use effect.

[0022] As a further preferred embodiment, hollow microspheres 21 are provided inside the vacuum microporous heat insulation layer 2. The hollow microspheres 21 use countless cavities in their unique spherical hollow structure to form a heat insulation layer to reduce heat conduction.

[0023] As a further preferred embodiment, the base layer 1 is a silicone-based resin layer.

[0025] The vacuum microporous thermal insulation layer 2 provides low thermal conductivity, heat resistance and heat insulation, while the reflective layer 4 gives the coating a higher infrared reflectivity and can efficiently reflect infrared radiation.

[0026] The ceramic fiber support layer 3 and the vacuum microporous insulation layer 2 with low thermal conductivity constitute an efficient heat shielding layer. The contact heat transfer between the reflective layer 4 needs to pass through the reflective layer 4, the reflective layer 4 and the ceramic fiber support layer 3, the ceramic fiber support layer 3 and the vacuum microporous insulation layer 2, and the base layer 1 and the auxiliary materials. Therefore, the contact thermal resistance is very large, and the thermal insulation control can be realized efficiently.

[0027] The thermal conversion topcoat layer 5 of acrylonitrile expansion powder serves as the outermost structure, which converts the heat reflected by the reflective layer 4 and the inside into radiation energy and releases it into the atmosphere. The thermal conversion topcoat layer 5 does not store heat, which greatly improves the thermal insulation effect of the coating. The coating is not easily contaminated, which extends its service life. It can be directly applied to the exterior wall surface with high operating efficiency.
