The energy-saving cooling heat-insulating film has thin thickness and transparent color, and has the reflectivity to infrared rays and ultraviolet rays up to 90 percent; and has good flexibility and contractibility, and is not easy to wrinkle and generate bubbles when adhered to an automobile. The preparation method of the energy-saving cooling heat-insulating vehicle cover is simple in flow, can effectively control the firmness and oxidation resistance of the metal material sputtered on the surface of the TPU or TPH base material, and does not influence the appearance and the heat-insulating effect due to any stretching or bending during preparation.
Description
Technical Field
The invention relates to a heat-insulating film, in particular to a invisible car cover film for cooling and heat insulation on the surface of a car body or a building body.
Background
Films conventionally applied to automotive glass and architectural glass, commonly referred to simply as window films, provide thermal insulation and ultraviolet protection. At present, the traditional window film cannot be adhered outdoors and is limited to be adhered to the inner side of automobile glass and building glass because of the limitations of scratch resistance, acid rain resistance, easy surface oxidation and flexibility. Taking an automobile as an example: about 40% of the temperature in the automobile is directly conducted by the roof of the automobile, 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 a part of the temperature around 60% of the automobile, but the problem that the heat on the metal surface of the automobile body is conducted into the automobile cannot be solved. The automobile body is exposed to sunlight for a long time to cause the temperature in the automobile to be too high, and long-time ultraviolet radiation to cause the surface of the automobile body to fade and accelerate the aging of materials.
In the prior art, the car cover attached to the outer surface of the car body or the building body only can solve the effect of protecting the surface, but can not effectively block the ultraviolet rays and the infrared radiation, so that a large amount of heat under the sun exposure can not be prevented from being blocked. In addition, the heat insulation film in the prior art adopts PET (polybutylene terephthalate) material as a matrix 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.
Disclosure of Invention
The invention provides an energy-saving cooling heat-insulating car cover film and a preparation method thereof. The energy-saving cooling heat-insulating car cover film can be used for the surfaces of automobiles or buildings, and plays a role in heat insulation, cooling and energy conservation in the sunlight exposure environment.
The energy-saving cooling heat-insulating car cover film comprises the following layers which are laminated in sequence:
(1) The thickness of the release film layer is 50-75 mu m;
(2) A first mounting adhesive layer (also referred to as a pressure-sensitive adhesive layer) having a thickness of 3 to 5 μm;
(3) A first base material layer having a thickness of 100 to 155 μm, and the material of the first base material layer is TPU (thermoplastic polyurethane elastomer) or TPH (thermoplastic elastomer);
(4) A first high refractive index layer having a thickness of 30 to 40nm;
(5) A first metal oxide layer having a thickness of 2 to 7nm;
(6) A first silver layer having a thickness of 8 to 12nm;
(7) A first barrier layer having a thickness of 0.2 to 0.45nm;
(8) A second high refractive index layer having a thickness of 65 to 72nm;
(9) A second metal oxide layer having a thickness of 5 to 9nm;
(10) A second silver layer with a thickness of 8-12 nm;
(11) A second barrier layer having a thickness of 0.2 to 0.45nm;
(12) A third high refractive index layer having a thickness of 25 to 30nm;
(13) A second mounting adhesive layer (also referred to as a pressure-sensitive adhesive layer) having a thickness of 3 to 5 μm;
(14) A second base material layer having a thickness of 50 to 150 μm, and a material of the second base material layer being TPU (thermoplastic polyurethane elastomer) or TPH (thermoplastic elastomer);
(15) The scratch-resistant layer has a thickness of 2-5 μm.
Further, the materials of the first high refractive index layer, the second high refractive index layer and the third high refractive index layer are titanium dioxide, the refractive index is 2.2-2.5, and the transparent area is 350-1200 nm.
Further, the materials of the first metal oxide layer and the second metal oxide layer are both ITO (indium tin oxide composite material) having a refractive index of 2.02.
Further, the material of the first barrier layer and the second barrier layer is nickel.
Further, the release film layer is a PET release film layer.
Further, the mounting adhesive layer is an acrylic pressure-sensitive adhesive layer.
Further, the scratch-resistant layer is made of wear-resistant polyurethane, and the hardness is as high as 4H.
Further, the visible light wave band transmittance of the first substrate layer is more than or equal to 88%.
The preparation method of the energy-saving cooling heat-insulating car cover film comprises the following steps:
(1) Coating an installation adhesive on one side of the first substrate through a coating process, and compounding a release film; wherein the first substrate is a TPU film or a TPH film;
(2) Sequentially sputtering titanium dioxide, ITO, silver, nickel, titanium dioxide, ITO, silver, nickel and titanium dioxide on the other side of the first substrate to form a first high refractive index layer, a first metal oxide layer, a first silver layer, a first barrier layer, a second high refractive index layer, a second metal oxide layer, a second silver layer, a second barrier layer and a third high refractive index layer;
(3) Uniformly coating mounting adhesive on one side of the third high refractive index layer, and attaching a second substrate; wherein the second substrate is a TPU film or a TPH film;
(4) A scratch resistant layer is formed on one side of the second substrate.
The energy-saving cooling heat-insulating car cover film can be used for heat insulation of the metal surface of an automobile or the surface of a building, is attached to the metal roof of the automobile, the metal plate on the surface or the surface of the building, can greatly improve the heat insulation performance of the automobile or the building, and avoids the heat of the automobile or the building from being transferred into the automobile and the building in a large amount under sunlight exposure.
The TPU or TPH base material has the characteristics of easy stretching, large contractibility and random bending, and based on the characteristic properties of the two base materials different from the PET base material, the energy-saving cooling heat-insulating car cover film can be prepared on the surface of the TPU or TPH base material in a magnetron sputtering mode. However, the energy-saving cooling heat-insulating car cover film cannot be prepared by a magnetron sputtering mode by using the production process for producing the PET heat-insulating film.
The invention has the beneficial effects that: the energy-saving cooling heat-insulating film provided by the invention has the advantages of thin thickness and transparent color, can be arbitrarily attached to the positions of automobile roofs and the like, and can reflect infrared rays and ultraviolet rays up to 90% under the condition that the color of the automobile is not influenced; and has good flexibility and contractibility, and is not easy to wrinkle and generate bubbles when adhered to an automobile. The preparation method of the energy-saving cooling heat-insulating vehicle cover provided by the invention has a simple flow, can effectively control the firmness and oxidation resistance of the metal material sputtered on the surface of the TPU or TPH base material, and does not influence the appearance and the heat-insulating effect due to any stretching or bending during the preparation.
