Description

Technical Field

[0001] The present application relates to the technical field of coating structures, and in particular to a heat-insulating coating with dust-proof and self-cleaning functions. Background Art

[0002] With the improvement of people's cognition and the continuous maturity of technology, the design, development and application of reflective thermal insulation coatings have been booming. Currently, reflective thermal insulation coating products are more common, and there are a large number of application cases in construction, warehousing, cold chain and other fields.

[0003] No matter which combination of reflective heat insulation products currently on the market is used, they will face a serious challenge. The continuous accumulation of dust has a great impact on the sunlight reflectance of the coating, which has seriously affected the service life and effect of the product design; even after two or three years of use, the actual effect of the sunlight reflectance of the reflective coating has dropped by 80%. Dust has become the number one factor threatening the effect of reflective heat insulation coatings.

[0006] The above-mentioned structural layer has a complex structure, and the cleaning layer is in direct contact with the reflective heat-insulating coating, which has poor insulation and cleaning effects, and cannot maintain a high reflectance to sunlight for a long time, and achieve a long-term heat insulation effect.

[0007] Therefore, it is necessary to provide a new technical solution to solve the above technical problems. Utility Model Content

[0020] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be noted that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0021] The present embodiment provides a heat-insulating coating with dust-proof and self-cleaning functions, including an isolation protective layer 1, wherein the isolation protective layer 1 adopts an inorganic doped isolation protective layer in the prior art. The present embodiment does not make any improvement to the material of the isolation protective layer 1, and can be selected from the prior art. The isolation protective layer 1 is provided with a reflective heat-insulating coating 3 on one side close to a substrate 2 (a coated body). Similarly, the present invention only protects the positional relationship between each layer body, but does not make any improvement to the material of the layer body itself. The reflective heat-insulating coating 3 adopts a reflective heat-insulating coating in the prior art. The color of layer 3 needs to match the original color of the substrate body. One side of the reflective thermal insulation coating 3 is coated on the substrate 2; the side of the isolation protective layer 1 away from the substrate 2 is provided with a dust-proof self-cleaning nano coating 4. The dust-proof self-cleaning nano coating 4 adopts the super-hydrophilic dust-proof self-cleaning nano coating in the prior art. The setting of the isolation protective layer 1 prevents the dust-proof self-cleaning nano coating 4 from directly contacting the reflective thermal insulation coating 3, thereby protecting the reflective thermal insulation coating 3 and avoiding catalytic decomposition by the special filler in the dust-proof self-cleaning nano coating 4, and enables the dust-proof self-cleaning nano coating 4 to form better adhesion on the reflective thermal insulation coating 3.

[0022] The film thickness of the above-mentioned reflective thermal insulation coating 3 is 600 microns to 800 microns, which can provide thermal insulation and heat preservation, and has a high sunlight reflectance ratio and can provide excellent reflective thermal insulation function; the film thickness of the dust-proof and self-cleaning nano-coating 4 is 100-150 nanometers, which has no effect on the reflectivity and color of the reflective thermal insulation coating 3, has excellent dustproofness and super hydrophilic self-cleaning function, and the ability to photocatalytically decompose organic matter, but because of the setting of the isolation protective layer 1, the reflective thermal insulation coating 3 will not produce catalytic decomposition.

[0023] The coating thickness of the inorganic doped isolation protective layer in this embodiment is 150 microns to 250 microns, and one of the inorganic-organic hybrid matte coating, inorganic-organic hybrid transparent coating, and inorganic-organic hybrid coating is used. When the transparent coating is used, it has no effect on the reflectivity and color of the reflective heat-insulating coating 3. When the inorganic-organic hybrid coating is used, it has better adhesion to the reflective heat-insulating coating 3 and the dust-proof self-cleaning nano coating 4 than the inorganic-organic hybrid matte coating and the inorganic-organic hybrid transparent coating. The isolation protective layer 1 provides a good grafting effect for the two functional coatings, which has a good effect on the reflective The functions of the thermal insulation coating 3 and the super-hydrophilic dust-proof and self-cleaning nano-coating have no negative impact, and provide good protection for the reflective thermal insulation coating 3. Through the setting of the isolation protective layer 1, the dust-proof and self-cleaning nano-coating 4 and the reflective thermal insulation coating 3 are not in direct contact, but cooperate with each other, which can effectively reduce the influence of long-term accumulation of dust and reflective insulation on the reflectivity of the reflective thermal insulation coating 3; and the inorganic doped isolation protective layer and the super-hydrophilic dust-proof and self-cleaning nano-coating in the present application have no negative impact on the function of the reflective thermal insulation coating 3, thereby improving the use effect of the reflective thermal insulation coating 3 and extending its service life.

[0024] This application has the following beneficial effects:

[0025] (1) By setting the isolation protection layer 1, the dustproof self-cleaning nano coating 4 and the reflective heat-insulating coating 3 are not in direct contact, thereby protecting the reflective heat-insulating coating 3 and preventing it from being catalytically decomposed by the special filler in the dustproof self-cleaning nano coating 4;

[0026] (2) The provision of the isolation protection layer 1 enables the dustproof self-cleaning nano coating 4 to form better adhesion on the reflective heat insulation coating 3;

[0027] (3) The cooperation between the isolation protection layer 1 and the dustproof self-cleaning nano coating 4 can better protect the reflective thermal insulation coating 3, reduce the impact of dust on the reflective thermal insulation coating 3, enhance the actual use effect of the product, and extend its service life.
