Description

Technical Field

[0001] This utility model relates to the field of reflective film technology, and in particular to a waterproof and durable reflective film. Background Technology

[0002] Reflective film is a special optical material with retroreflective properties. Through the microprism structure or glass bead technology on the surface, it can reflect light back to the source along the original path, thereby significantly improving the visibility of the target object at night or in low light environment.

[0003] The applicant discovered a Chinese patent, "A Waterproof and Durable Reflective Sheet," with publication number CN218412953U. This patent primarily protects the reflective sheet by incorporating a waterproof layer structure, reducing the likelihood of water seeping into the sheet and thus preventing water from affecting its reflective effect, ultimately improving its practicality. The waterproof layer structure is further protected by a protective resin layer and square protrusions, reducing the chance of it detaching from the sheet. However, this patent lacks auxiliary positioning tools, requiring manual alignment during installation, which can easily lead to misalignment or positional deviations. This is particularly inefficient for large-area reflective sheet installation, as manual alignment alone can cause uneven reflective effects or compliance issues in scenarios requiring strict dimensional accuracy. Therefore, we propose a waterproof and durable reflective sheet. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof and durable reflective film to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof and durable reflective film, comprising a reflective film body and an auxiliary installation mechanism disposed on its outer side, the auxiliary installation mechanism comprising a positioning film, a tear-off film pasted to the bottom of the positioning film, scale lines formed on the upper surface of the positioning film, a positioning element connected to the positioning film through a slot, a sealing plug connected to the positioning element through an air hole, a insertion tube connected to the positioning element through an installation slot, a suction cup fixedly installed at the bottom of the insertion tube, and an easy-tear connecting film fixedly installed on the inner side of the positioning film.

[0006] As a preferred embodiment, the end of the easy-tear connecting film away from the positioning film is fixedly installed on the outer side of the reflective film body, and an easy-tear groove is provided between the reflective film body and the easy-tear connecting film.

[0007] As a preferred embodiment, the slot penetrates the corner surface of the positioning film, the positioning element is fixedly installed inside the slot, the air hole is opened on the outer wall of the positioning element near the upper end, the sealing plug is inserted into the air hole, and a flexible element is fixedly connected between the sealing plug and the positioning element.

[0008] As a preferred embodiment, the mounting groove is formed at the bottom of the positioning member, and the insertion tube is inserted into the interior of the mounting groove.

[0009] As a preferred embodiment, the reflective film body comprises, from top to bottom, a base layer, a reflective layer, a waterproof reinforcement layer, a heat dissipation layer, an electromagnetic shielding layer, a reflective layer, and a protective coating.

The easy-tear connecting film can quickly separate the auxiliary installation mechanism from the reflective film without affecting the use.

[0013] 2. By combining nano-silica particles with PUA resin in the waterproof reinforcement layer, and the hydrophobic and oleophobic properties of the fluorinated acrylate in the protective coating, a double waterproof structure is formed, which can effectively prevent water penetration and maintain good performance even in long-term humid or rainy environments, preventing the reflective film from being damaged by moisture.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see the appendix Figure 1 - Appendix Figure 6A waterproof and durable reflective film includes a reflective film body 1 and an auxiliary installation mechanism 2 disposed on its outer side. The auxiliary installation mechanism 2 includes a positioning film 201, a tear-off film 204 pasted on the bottom of the positioning film 201, and scale lines 203 on the upper surface of the positioning film 201. The positioning film 201 is connected to a positioning element 207 through a slot 202. The positioning element 207 is connected to a sealing plug 210 through an air hole 208. The positioning element 207 is connected to a plug tube 212 through an installation groove 211. A suction cup 213 is fixedly installed at the bottom of the plug tube 212. An easy-tear connecting film 205 is fixedly installed on the inner side of the positioning film 201.

[0025] Users can precisely cut the required reflective size according to the scale line 203. The peel-off film 204 and the positioning film 201 are bonded with non-adhesive, leaving no trace after removal.

[0026] The end of the easy-tear connecting film 205 away from the positioning film 201 is fixedly installed on the outer side of the reflective film body 1, and an easy-tear groove 206 is provided between the reflective film body 1 and the easy-tear connecting film 205.

[0027] The design of the easy-tear connecting film 205 and the easy-tear groove 206 allows the easy-tear connecting film 205 to be easily peeled off along the easy-tear groove 206 when the reflective film needs to be removed, thus separating the reflective film from the positioning film 201.

[0028] The slot 202 penetrates the corner surface of the positioning film 201. The positioning element 207 is fixedly installed inside the slot 202. The air hole 208 is opened on the outer wall of the positioning element 207 near the upper end. The sealing plug 210 is inserted into the air hole 208. A flexible element 209 is fixedly connected between the sealing plug 210 and the positioning element 207.

[0029] The suction cup 213 can be quickly released by pulling out the sealing plug 210, which is convenient to operate. At the same time, the flexible part 209 can be deformed to ensure that the sealing plug 210 can be easily removed and will not fall off.

[0030] The mounting groove 211 is located at the bottom of the positioning member 207, and the insertion tube 212 is inserted into the interior of the mounting groove 211.

[0031] Specifically, the positioning component 207 is connected to the sealing plug 210 through the air hole 208, and the bottom is connected to the insertion pipe 212 and the suction cup 213 through the mounting groove 211. When it is necessary to fix the reflective film, the sealing plug 210 is opened, and the air hole 208 is used to expel the air in the suction cup 213, forming a negative pressure, so that the suction cup 213 is tightly adsorbed on the installation surface. The peel-off film 204 is then peeled off, and the positioning film 201 can be attached to the target installation position, which simplifies the cumbersome installation process of traditional reflective films. At the same time, the scale lines 203 on the positioning film 201 can help installers accurately determine the installation size and position of the reflective film, avoiding rework due to installation errors and greatly improving installation efficiency. The easy-tear connecting film 205 can quickly separate the auxiliary installation mechanism 2 from the reflective film without affecting its use.

[0032] Please see the appendix Figure 1 and attached Figure 7 The reflective film body 1 comprises, from top to bottom, a base layer 101, a reflective layer 102, a waterproof reinforcement layer 103, a heat dissipation layer 104, an electromagnetic shielding layer 105, a reflective layer 106, and a protective coating 107. The base layer 101 is made of polyethylene terephthalate, the reflective layer 102 is a vacuum-deposited aluminum layer, the waterproof reinforcement layer 103 is composed of polyurethane acrylate resin and nano-silica particles, the heat dissipation layer 104 is composed of graphene nanosheets and silicone, the electromagnetic shielding layer 105 is composed of silver-plated copper mesh and conductive polymer, the reflective layer 106 is composed of a microprism structure, and the protective coating 107 is a fluorinated acrylate coating.

[0033] The base layer 101 provides a stable support structure for the entire reflective film, ensuring that it is not easily deformed during use. The reflective layer 102 forms a uniform and dense aluminum layer on the surface of the base layer 101 through a vacuum evaporation process. This aluminum layer can efficiently reflect light, providing basic reflective performance for the reflective film. In the waterproof reinforcement layer 103, nano-silica particles are uniformly dispersed in PUA resin, which can effectively fill the gaps between resin molecules, improve the density and waterproof performance of the waterproof reinforcement layer 103, and enhance its hardness and wear resistance, thus playing a reinforcing role. The heat dissipation layer 104 contains stone... The excellent thermal conductivity of graphene nanosheets combined with the good flexibility of silicone can quickly conduct and dissipate the heat generated by the reflective film during use, avoiding performance degradation or accelerated aging of the reflective film due to high temperature. The microprism structure of reflective layer 106 can totally reflect incident light, greatly improving the reflective efficiency and reflective intensity of the reflective film. The fluorinated acrylate in protective coating 107 has extremely low surface energy, which enables the surface of protective coating 107 to form hydrophobic and oleophobic properties, effectively preventing water stains and dirt from adhering to the surface of the reflective film, further enhancing its waterproof performance and self-cleaning ability.

[0034] Specifically, the composite of nano-silica particles and PUA resin in the waterproof reinforcement layer 103, along with the hydrophobic and oleophobic properties of the fluorinated acrylate in the protective coating 107, forms a double waterproof structure that effectively prevents water penetration. Even in long-term humid or rainy environments, it can maintain good performance and prevent the reflective film from being damaged by moisture. The base layer 101 provides stable support, the waterproof reinforcement layer 103 enhances hardness and wear resistance, the heat dissipation layer 104 prevents high-temperature aging, the electromagnetic shielding layer 105 prevents electromagnetic interference and oxidation, the protective coating 107 prevents surface damage, and the microprism structure of the reflective layer 106 uses robust PC material, enabling the reflective film to withstand various adverse factors and preventing aging, peeling, deformation, and other phenomena, thus greatly extending its service life.

[0035] The working principle of this utility model is as follows: This utility model is a waterproof and durable reflective film. First, according to the installation position, the insertion tube 212 is inserted into the mounting groove 211 at the bottom of the positioning component 207, so that the suction cup 213 at the bottom of the insertion tube 212 is in close contact with the installation surface. Then, the sealing plug 210 is opened, and the air in the suction cup 213 is discharged through the air hole 208. Then, the sealing plug 210 is tightened to form a negative pressure, so that the suction cup 213 is firmly adsorbed onto the installation surface. Then, the tear-off film 204 at the bottom of the positioning film 201 is peeled off, at which point the adhesive side of the positioning film 201 is exposed. According to the actual needs, the installer uses the scale lines 203 on the upper surface of the positioning film 201 to accurately position the target installation location, determining the installation size, angle, and position of the reflective film. After the positioning film 201 is fixed, the reflective film body 1 is directly attached to the target position. Finally, remove the sealing plug 210 to detach the suction cup 213 from the mounting surface, and peel off the easy-tear connecting film 205 along the easy-tear groove 206 to separate the reflective film body 1 from the positioning film 201, thus completing the installation of the reflective film. During use, the various layers of the reflective film body 1 work together. The protective coating 107, with its extremely low surface energy, forms hydrophobic and oleophobic properties, preventing water stains and dirt from adhering, protecting the internal structure and maintaining the reflective effect; the reflective layer 106 completely reflects incident light, achieving efficient reflection; the electromagnetic shielding layer 105 shields external electromagnetic interference, ensuring normal use in complex electromagnetic environments, while the conductive polymer protects the silver-plated copper mesh against oxidation; the heat dissipation layer 104, composed of graphene nanosheets and silicone, quickly conducts and dissipates heat generated during use, preventing performance degradation or accelerated aging due to high temperatures; the waterproof reinforcement layer 103 fills gaps to improve density, enhancing waterproofness, hardness, and wear resistance; the vacuum-deposited aluminum layer of the reflective layer 102 efficiently reflects light, providing basic reflective performance; the base layer 101 provides stable support for the entire reflective film, ensuring it is not easily deformed during use.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
