Description

Technical Field

[0001] This utility model relates to the field of reflective sheet technology, specifically a cold-resistant rigid PVC reflective sheet. Background Technology

[0002] PVC reflective sheets are a commonly used reflective component used to reflect light emitted by a light source in low ambient light conditions, thereby achieving a warning effect.

[0003] Chinese utility model patent, authorization announcement number CN219007292U, discloses a user-friendly PVC reflective sheet, comprising multiple reflective composite layers. Adjacent reflective composite layers are connected by a connecting layer, which includes a tearable connecting piece. The connecting piece is fixedly connected to both adjacent reflective composite layers, and an inner film is fixedly disposed on the connecting piece, located between the two adjacent reflective composite layers. This utility model's PVC reflective sheet allows for the selection of an appropriate number and arrangement of reflective composite layers according to actual usage needs. The required reflective composite layer can then be separated by tearing the connecting piece, eliminating the need for specialized cutting operations and simplifying the process.

[0004] The above solution solves the technical problems mentioned in the background technology. However, in practical applications, the above solution still has certain defects. For example, the existing technology and existing PVC reflective sheets have poor cold resistance. This is because PVC sheets become brittle at low temperatures, their impact strength decreases significantly, and they are prone to cracking, breaking or peeling. Utility Model Content

[0005] The purpose of this invention is to provide a cold-resistant rigid PVC reflective sheet to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cold-resistant rigid PVC reflector, comprising a reflector body, wherein the reflector body comprises a rigid PVC board, and a cold-resistant layer is fixed to the top and bottom of the rigid PVC board. The bottom of the cold-resistant layer located at the bottom of the rigid PVC board is provided with an adhesive backing layer and an anti-sticking layer from top to bottom.

[0007] The cold-resistant layer located on top of the rigid PVC board has a microprism layer and a protective film arranged sequentially from bottom to top.

[0008] Preferably, an elastic layer is provided between the cold-resistant layer and the adhesive layer at the bottom of the rigid PVC board.

[0009] Preferably, a side protective layer is provided on the outer side of the reflector body.

[0010] Preferably, the length of the side protective layer is equal to the sum of the thicknesses of the rigid PVC board, the two cold-resistant layers, the elastic layer, the microprism layer, and the protective film.

[0011] Preferably, the elastic layer is made of a corrosion-resistant rubber material.

[0012] Preferably, the cold-resistant layer is made of polyurethane material.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This cold-resistant rigid PVC reflector has a cold-resistant layer fixed to both the top and bottom of the rigid PVC board. The cold-resistant layer is made of polyurethane material. By setting the cold-resistant layer, the cold resistance of the PVC board can be increased, preventing it from cracking due to low-temperature brittleness.

[0015] Meanwhile, an elastic layer is provided. The purpose of the elastic layer is firstly to buffer external impact forces, improve the overall structural stability of the PVC reflector and effectively prevent the rigid PVC board from breaking due to force. Secondly, based on the good elasticity of the elastic layer, it can also effectively prevent the rigid PVC board from breaking due to thermal expansion and contraction, thereby improving the service life of the reflector.

[0016] In addition, a side protective layer is provided to prevent air from contacting the reflector body through the joints between the corresponding connecting layers, thereby reducing the aging time of the reflector body and improving the service life of the reflector.

[0020] 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.

[0021] PVC reflective sheets are a commonly used reflective component used to reflect light emitted by a light source in low ambient light conditions to achieve a warning effect. However, existing technology and existing PVC reflective sheets have poor cold resistance. This is because PVC sheets become brittle at low temperatures, their impact strength decreases significantly, and they are prone to cracking, breaking, or peeling.

[0022] like Figures 1-2 As shown, this utility model provides a technical solution: a cold-resistant rigid PVC reflector, including a rigid PVC board 101. Rigid PVC board is a widely used engineering plastic sheet, made from polyvinyl chloride resin with added stabilizers, fillers, lubricants, and other additives, through extrusion or calendering processes. A cold-resistant layer 102 made of polyurethane material is fixed to both the top and bottom of the rigid PVC board 101. The thickness of the cold-resistant layer 102 is 0.5-1mm. Polyurethane is a highly versatile polymer synthetic material, made by reacting isocyanate with polyols. Its molecular structure is highly designable; by adjusting the raw material ratio, additives, and processes, products ranging from soft foam to rigid plastic can be obtained. The cold-resistant layer 102 increases the cold resistance of the PVC board 101, preventing it from cracking due to low-temperature brittleness. From top to bottom, the bottom of the cold-resistant layer 102 at the bottom of the rigid PVC board 101 is provided with an adhesive backing layer 106 and an anti-sticking layer 107.

[0023] When using, simply peel the anti-stick layer 107 off the adhesive layer 106, and then stick the adhesive layer 106 onto the surface of the object to be warned.

[0024] The top of the cold-resistant layer 102 on the top of the rigid PVC board 101 is provided with a microprism layer 103 and a protective film 104 from bottom to top. The multiple continuous microcrystalline units in the microprism layer 103 are the same size and have the same refractive index. Therefore, when light shines on the reflector, the entire reflector can achieve uniform light reflection to ensure the visibility of the reflective sign. In addition, the protective film 104 is made of transparent resin. Since the protective film 104 is transparent, it can effectively reduce the impact on the reflected light.

[0025] In another embodiment of this solution, an elastic layer 105 made of corrosion-resistant rubber material is provided between the cold-resistant layer 102 and the adhesive backing layer 106 at the bottom of the rigid PVC sheet 101. The purpose of the elastic layer 105 is, firstly, to buffer the impact force from the outside, improve the overall stability of the PVC reflector structure and effectively prevent the rigid PVC sheet 101 from breaking and being damaged due to force. Secondly, based on the good elasticity of the elastic layer 105, it can also effectively prevent the rigid PVC sheet 101 from breaking and being damaged due to thermal expansion and contraction.

[0026] To improve the sealing performance of the PVC reflector, a side protective layer 2 is provided on the outside of the reflector body 1. To prevent air from contacting the reflector body 1 through the joints between the corresponding connecting layers, thereby reducing the aging time of the reflector body 1 and improving the service life of the reflector, the side protective layer 2 is provided on the outside of the rigid PVC board 101, the two cold-resistant layers 102, the elastic layer 105, the microprism layer 103, and the protective film 104 after they are fixed together. Specifically, after the rigid PVC board 101, the two cold-resistant layers 102, the elastic layer 105, the microprism layer 103, and the protective film 104 are fixed together, waterproof adhesive is applied to the outside of them. After the waterproof adhesive is fixed, the side protective layer 2 is formed. In addition, in this solution, the length of the side protective layer 2 is equal to the sum of the thicknesses of the rigid PVC board 101, the two cold-resistant layers 102, the elastic layer 105, the microprism layer 103, and the protective film 104.

[0027] In this design, a rigid PVC sheet 101, two cold-resistant layers 102, an elastic layer 105, a microprism layer 103, and a protective film 104 are fixed together to form a PVC reflective sheet.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
