Description
Technical Field
The utility model relates to a thermal-insulated membrane, concretely relates to be used for the thermal-insulated stealthy car clothing membrane of cooling on automobile body or building object surface.
Background
Conventional adhesive films, often referred to simply as window films, are applied to automotive glass and architectural glass to provide thermal insulation and uv protection. The traditional window film at present can not be pasted outdoors because of the limitations of scratch resistance, acid rain resistance, easy oxidation of the surface and flexibility, and is limited to be pasted on the inner sides of automobile glass and building glass. Taking an automobile as an example: about 40% of the temperature in the automobile is directly conducted by the automobile roof, and about 60% of the temperature is directly conducted by the periphery of the automobile. The existing double-silver high-heat-insulation window film can only solve one part of the temperature of about 60% of the periphery of an automobile, and the problem that heat on the metal surface of an automobile body is conducted into the automobile cannot be solved. The automobile body is exposed to sunlight for a long time to cause the over-high temperature in the automobile, and the ultraviolet radiation for a long time causes the fading of the surface of the automobile body and the aging of accelerated materials.
In the prior art, the car cover attached to the outer surface of the car body or the building body can only protect the surface, but cannot effectively block the ultraviolet radiation and the infrared radiation, so that a large amount of heat under sunlight exposure cannot be prevented from being blocked. In addition, the heat insulation film in the prior art adopts a PET (polybutylene terephthalate) material as a base material, and is limited to be attached to the outer surfaces of automobile bodies and building objects due to the limitations of scratch resistance, acid rain resistance, easy surface oxidation and flexibility.

(1) firstly, a PET release film 1 is provided, and the PET release film is not deformed when being pulled up under the condition of tension of 250-300N.
(2) Providing a flexible transparent TPU or TPH film as a first substrate layer 3, coating mounting glue (a first mounting glue layer 2) on the surface of the first substrate layer, and compounding a PET release film 1. The purpose of installing the special release film is to enable the flexible transparent TPU or TPH film to stretch under the condition of 250-300N tension in the magnetron sputtering process without deformation, so that the TPU or TPH film can be used as a coating substrate, and the process requirement of sputtering a metal material (titanium dioxide, ITO, silver or nickel) on the TPU or TPH film is met.
(3) Depositing a first high-refractive-index layer 4 on the first substrate layer 3 in a double-rotating cathode and medium-frequency reactive magnetron sputtering mode; the material of the first high refractive-index layer 4 is preferably titanium dioxide, and its refractive index is 2.35. Titanium dioxide is directly deposited on the TPU or TPH film in a magnetron sputtering mode, and due to the fact that good adhesion force exists between the ITO and the TPU or TPH film, the ITO can be directly deposited on the TPU or TPH film on which the titanium dioxide is deposited, and extra metal coating treatment is not needed to be carried out on the TPU or TPH film to improve the adhesion force.
(4) Depositing a first metal oxide layer 5 on the first high-refractive-index layer 4 by a single-rotating cathode and a direct-current reactive magnetron sputtering mode; the material of the first metal oxide layer 5 is preferably ITO, which has a refractive index of 2.02. The purpose of depositing the metal oxide layer 5 is to promote the growth of the subsequent silver layer and enable the subsequent silver layer to grow into a continuous compact structure as soon as possible, so that the thickness of the subsequent silver layer is obviously reduced, the reflectivity of a visible light wave band of the heat-insulating car cover is reduced, and the original color of the original metal car paint can be visually seen under the visual condition. Meanwhile, the compact silver layer can effectively reflect infrared rays and ultraviolet rays, and the heat insulation performance of the heat insulation vehicle cover is improved.

The thickness and the refractive index of the second high refractive index layer 8 are larger than those of other high refractive index layers, namely, the second high refractive index layer 8 with larger refractive index is arranged between the two silver layers, and a double-reflection structure for reflecting infrared rays and ultraviolet rays can be formed by utilizing the smaller interval between the two silver layers, so that the thickness of the second high refractive index layer 8 can be reduced, and the reflectivity of the visible light wave band of the heat-insulation car cover can be reduced.
(8) Depositing a second metal oxide layer 9 on the second high refractive index layer 8 by a single rotating cathode and a direct current reactive magnetron sputtering mode; the material of the second metal oxide layer 9 is preferably ITO, which has a refractive index of 2.02. The thickness of the second metal oxide layer 9 deposited in this step is slightly greater than the thickness of the first metal oxide layer 5 in the previous step (4), and more infrared and ultraviolet rays are reflected by the thicker outer second silver layer 10.
(9) A second silver layer 10 is deposited on the second metal oxide layer 9 by means of a single-plane cathode, direct current reactive magnetron sputtering. The arrangement of the second silver layer 10 forms a double-reflection structure for reflecting infrared rays and ultraviolet rays, so that the visible light reflectivity of the heat-insulation vehicle cover is reduced more greatly, and the heat-insulation performance is enhanced.
(10) Depositing a second barrier layer 11 on the second silver layer 10 by a single-plane cathode and direct-current reactive magnetron sputtering mode; the material of the second barrier layer 11 is preferably nickel. As in step (6), oxidation is prevented, so that the service life of the infrared light reflectivity of the second silver layer 11 is prolonged, and a lasting high heat insulation effect is ensured.
