Description

Technical Field

[0001] The utility model relates to the technical field of heat insulation protective films, and more specifically, to a PET heat insulation protective film. Background Art

[0002] A PET heat insulation protective film is a protective film with heat insulation function made of polyethylene terephthalate (PET) as the base material by adding various functional materials and adopting specific processes. The existing PET heat insulation protective films are often applied in the fields of construction, automobiles, and electronic devices.

[0003] During the actual use of the existing PET heat insulation protective films, they usually rely on a single material for heat insulation protection, and their heat insulation effect is not ideal. Moreover, when used in the construction field, dust often easily adheres to the outer wall of the heat insulation protective film, which will undoubtedly affect the aesthetics of the surface of the protected doors and windows. And when cleaning, it is also inconvenient for personnel, who need to use a rag to wipe and clean, which undoubtedly causes many inconveniences in actual use. Moreover, their heat insulation protective films often lack a certain buffering ability. When a person collides with the window glass, it is extremely easy for the window glass to be damaged due to external impact.

[0004] Moreover, when the existing PET heat insulation protective films are in use, they often need to be spliced to adapt to the pasting on larger doors and windows. When the existing PET heat insulation protective films are adhered, the edges often become uneven due to improper operation by personnel, which will undoubtedly affect their pasting aesthetics. Moreover, large gaps often appear at their edges, and external moisture can easily enter the edge adhesion layer through these gaps, thereby affecting the adhesion effect of the adhesion layer to a certain extent, causing many troubles in actual use.

[0005] In view of this, we propose a PET heat insulation protective film. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a PET heat insulation protective film to solve the problems raised in the above background art.

[0008] 2. Technical Solutions

[0009] A PET heat insulation protective film includes a PET base material layer. An attachment film is arranged on the top of the PET base material layer. An ultraviolet resistance layer is arranged on the top of the attachment film. A self-cleaning layer is arranged on the top of the ultraviolet resistance layer.

[0010] Preferably, an adhesion layer is arranged on the bottom of the PET base material layer, and a release film is adhered to the bottom of the adhesion layer.

[0011] Preferably, a groove is formed at the top of the PET base material layer, a buffer silica gel is arranged on the inner wall of the groove, and a source heat insulation layer is arranged on the top of the plurality of buffer silica gels.

[0012] Preferably, a sealed splicing seat is arranged on the outer wall of one side of the PET base material layer, an adhesive layer II is arranged at the bottom of the sealed splicing seat, and a clamping groove is formed at the top of the sealed splicing seat.

[0013] Preferably, a sealing strip is arranged on the outer wall of the other side of the PET base material layer, and a clamping strip matched with the clamping groove is arranged at the bottom of the sealing strip.

[0014] Preferably, the ultraviolet resistant layer is sprayed on the top of the attachment film, and the attachment film is adhered to the top of the source heat insulation layer.

[0015] Preferably, the self-cleaning layer comprises a protective film, nano microstructures are formed on the top of the protective film, and a hydrophobic layer is sprayed on the top of the nano microstructures.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present utility model are as follows: When the PET heat-insulating protective film is in use, the sunlight from the outside can be refracted and insulated first by the PET substrate layer, the source heat-insulating layer and the ultraviolet-resistant layer. The main function of the PET substrate layer is heat insulation. It can effectively block the transfer of heat and reduce the temperature rise of the object to be protected. The source heat-insulating layer is an additional layer with an active heat-insulating function in the PET substrate layer. Through specific materials and technologies, it can actively absorb or release heat when the temperature changes, thereby further improving the heat-insulating effect of the protective film. The ultraviolet-resistant layer is mainly used to block the penetration of ultraviolet rays and protect the object to be protected from damage by ultraviolet rays. Ultraviolet rays can cause the object to fade, age, embrittle, etc. Therefore, adding the ultraviolet-resistant layer can improve the comprehensive performance of the protective film. Moreover, on this basis, buffer silica gels are arranged inside the top groove of the PET substrate layer, which can provide a certain buffer effect to a certain extent, reduce the collision of external forces on the glass or the object to be protected, and an air interlayer will be formed inside the top groove of the PET substrate layer under the action of multiple buffer silica gels. Since air has a low thermal conductivity coefficient, the heat-insulating effect can be further enhanced. Secondly, the super-hydrophobic surface of the self-cleaning layer has a special micro-structure, usually composed of nano-scale or micro-scale rough structures. These rough structures can make water droplets form spherical shapes on the surface, greatly reducing the contact area with the surface. For example, the surface may have papilla structures similar to the surface of a lotus leaf. This structure makes the water droplets in a "suspended" state on the surface, difficult to adhere and infiltrate. And due to the design of the hydrophobic layer, only by spraying water on the surface of the protective film, under the action of surface tension and natural power, the rolling water droplets can carry away stains and prevent stains from penetrating, making it convenient for later cleaning. And due to the hydrophobic design itself, the contact area is small, and the adhesion between the stain particles and the surface is weakened, making it difficult for the stains to firmly adhere to the surface, further enhancing the functionality of the PET heat-insulating protective film;

[0018] When it is necessary to splice multiple PET heat-insulating protective films, the clamping strip on one side of the PET substrate layer can be clamped into the clamping groove on one side of another PET heat-insulating protective film. Under the guidance of this pasting, the uneven pasting situation can be reduced to a certain extent, and the generation of gaps can be effectively reduced, avoiding the infiltration of moisture and affecting its adhesion effect.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] Please refer to the figure. The present utility model provides a technical solution:

[0028] A PET heat insulation protective film, including a PET substrate layer 100, an attachment film 200 is provided on the top of the PET substrate layer 100, an anti-ultraviolet layer 300 is provided on the top of the attachment film 200, and a self-cleaning layer 400 is provided on the top of the anti-ultraviolet layer 300.

[0029] In some embodiments: The adhesion film 200 is made of transparent polyethylene, and the ultraviolet resistance layer 300 is an ultraviolet absorber, such as organic compounds like benzotriazoles and benzophenones. These ultraviolet absorbers can absorb ultraviolet rays and convert them into heat energy or other forms of energy for release, thereby reducing the damage of ultraviolet rays to the protected object.

[0030] Specifically, an adhesion layer 110 is provided at the bottom of the PET substrate layer 100, and a release film 120 is adhered to the bottom of the adhesion layer 110. The adhesion layer 110 is a pressure-sensitive adhesive.

[0031] Furthermore, a groove is provided at the top of the PET substrate layer 100, a buffer silica gel 130 is provided on the inner wall of the groove, and a source heat insulation layer 140 is provided on the top of multiple buffer silica gels 130.

[0032] In some embodiments: The source heat insulation layer 140 is made of a phase change material, such as paraffin microcapsules. Paraffin undergoes solid-liquid phase change within a specific temperature range and absorbs or releases a large amount of latent heat during the phase change process. Encapsulating paraffin in microcapsules can enable it to better combine with other materials, while avoiding the leakage and loss of paraffin. Other materials with heat storage functions, such as certain inorganic salt compounds, can also be used as the material of the source heat insulation layer, and they can absorb or release heat through chemical reactions or physical changes when the temperature changes.

[0033] Still further, a sealed splicing seat 150 is provided on the outer wall of one side of the PET substrate layer 100. An adhesion layer two 151 is provided at the bottom of the sealed splicing seat 150, and a card slot 152 is provided at the top of the sealed splicing seat 150.

[0034] Even further, a sealing strip 160 is provided on the outer wall of the other side of the PET substrate layer 100. A clamping strip 161 that matches the card slot 152 is provided at the bottom of the sealing strip 160, which is convenient for providing better aesthetics when splicing multiple PET heat insulation protection films, and reducing the influence of water sealing through gaps on the adhesion firmness.

[0035] It should be noted that the ultraviolet resistance layer 300 is sprayed on the top of the adhesion film 200, and the adhesion film 200 is adhered to the top of the source heat insulation layer 140.

[0036] It should be noted that the self-cleaning layer 400 includes a protective film. Nano-microstructures are provided on the top of the protective film, and a hydrophobic layer is sprayed on the top of the nano-microstructures.

[0037] In some embodiments: The nano-microstructure is usually composed of rough structures at the nano-scale or micro-scale. These rough structures make water droplets form spherical shapes on the surface, greatly reducing the contact area with the surface. For example, there are papillary structures similar to those on the lotus leaf surface on the surface. This structure makes the water droplets in a "suspended" state on the surface, difficult to attach and infiltrate. The hydrophobic layer material is fluorocarbon compounds, siloxanes, etc. These materials have extremely low surface energy, enabling water droplets to form spherical shapes and roll off on their surfaces, taking away pollutants such as dust, thus achieving the effect of self-cleaning.

[0038] Working principle: During the use of the PET heat insulation protective film, first, the PET substrate layer 100, the source heat insulation layer 140, and the ultraviolet-resistant layer 300 work together for heat insulation. The PET substrate layer 100 serves as the main body of heat insulation, capable of effectively blocking heat transfer and reducing the temperature rise of the object to be protected. The source heat insulation layer 140 is a structure with an active heat insulation function added to the PET substrate layer 100. Through specific materials and technologies, it actively absorbs or releases heat when the temperature changes, further enhancing the heat insulation effect of the PET heat insulation protective film. The ultraviolet-resistant layer 300 is mainly used to block the penetration of ultraviolet rays and protect the object to be protected from the damage of ultraviolet rays. Since ultraviolet rays can cause the object to fade, age, embrittle, etc., adding the ultraviolet-resistant layer can significantly improve the comprehensive performance of the protective film. In addition, buffer silica gels 130 are arranged inside the top groove of the PET substrate layer 100. On the one hand, the buffer silica gels 130 can provide a buffer effect to a certain extent, reducing the damage caused by external force collisions to the glass or the object to be protected. On the other hand, multiple buffer silica gels 130 form an air interlayer inside the top groove of the PET substrate layer, and air has a low heat conduction coefficient, which can further enhance the heat insulation effect. Secondly, the surface of the self-cleaning layer 400 has a special microstructure, usually composed of rough structures at the nano-scale or micro-scale. These rough structures make water droplets form spherical shapes on the surface, greatly reducing the contact area with the surface. For example, there are papillary structures similar to those on the lotus leaf surface on the surface. This structure makes the water droplets in a "suspended" state on the surface, difficult to attach and infiltrate. And due to the hydrophobic layer design, only by spraying water on the surface of the protective film, under the action of surface tension and natural power, the rolling water droplets can take away stains and prevent the penetration of stains, making it convenient for later cleaning. Moreover, the hydrophobic design itself makes the contact area small, weakening the adhesion between the stain particles and the surface, and the stains are difficult to firmly adhere to the surface, further enhancing the functionality of the PET heat insulation protective film.

[0039] When it is necessary to splice multiple PET heat insulation protection films, the clamping strip 161 on one side of the PET substrate layer can be clamped in the card slot 152 on one side of another PET heat insulation protection film. Under the action of this guiding paste, on the one hand, the situation of uneven pasting can be reduced to a certain extent, and on the other hand, the generation of gaps can be effectively reduced, avoiding the infiltration of moisture and affecting the firmness of its adhesion.
