AI Technical Summary
Existing reflective films lack waterproof design, allowing rainwater to easily seep in, resulting in reduced retroreflective effect and short service life.
A waterproof layer is applied to the surface of the protective layer, and a raised rib structure is provided on the waterproof layer to form drainage channels. Combined with PET material and an aluminum or silver-plated reflective layer, the waterproof performance is enhanced, and the light reflection effect is improved by the refractive index of the raised ribs.
It effectively prevents moisture from entering the reflective film, reduces surface moisture, improves waterproofing, and makes the markings clearer and more visible through the light-focusing effect of the raised ridges, thus improving safety during use.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of reflective film, especially a waterproof reflective film. BACKGROUND
[0002] Reflective film is a kind of inverse reflection material that has been made into film and can be directly applied, which is made by glass bead technology, micro-prism technology, synthetic resin technology, film technology and coating technology and micro-replication technology.Reflective film is usually applied in the field of transportation, especially when people travel in rainy days or at night, they can discover signs and reflective objects in front of the driving route earlier, effectively forewarn the dangerous situation of the road in front, and provide safety guarantee for people's travel.The existing reflective film is mostly used outdoors, and is easily wetted by rain in rainy weather, because of lacking waterproof design, rainwater penetrates into the reflective film, reduces the inverse reflection effect of the reflective film, and leads to short service life of the reflective film. SUMMARY
[0003] The utility model provides a waterproof reflective film to solve the problems that the existing reflective film lacks waterproof design, rainwater easily penetrates, and leads to reduced inverse reflection effect of the reflective film.
[0004] The utility model adopts the following technical scheme:
[0005] A waterproof reflective film, comprising protective layer, micro-prism layer, reflective layer and base layer which are compounded in sequence, the surface of the protective layer is coated with waterproof layer, the waterproof layer is provided with a plurality of convex ridges, and drainage grooves are formed between the convex ridges.
[0006] Further, the cross section of the convex ridge is fan-shaped structure.
[0007] Further, the edges of the protective layer, the micro-prism layer, the reflective layer and the base layer are provided with edge sealing waterproof film.
[0008] Further, the base layer is composed of back adhesive layer and release paper, and the back adhesive layer is bonded to the reflective layer on the side away from the release paper.
[0009] Further, the reflective layer is aluminum plating layer or silver plating layer.
[0010] Further, the protective layer is made of PET material.
[0011] From the above description of the structure of the utility model, compared with the prior art, the utility model has the following advantages:
[0012] 1. The surface of the protective layer of the application is coated with waterproof layer, the waterproof layer prevents water from entering the reflective film, the surface of the waterproof layer is provided with convex ridges, the convex ridges directly form drainage grooves, the drainage grooves drain surface rainwater, greatly reduce the water on the surface of the waterproof layer, and improve the waterproof effect.
[0013] 2. The convex ridge of the present application has a fan-shaped structure, and because the refractive index of the convex ridge is greater than that of air, when external light enters the waterproof layer, the incident angle is greater than the exit angle, the light is refracted into the protective layer, and for the same reason, the light is refracted again into the micro-prism layer, the convex ridge has a light condensing effect on external light, and then is emitted along the direction away from the vertical reflective film, and the high-strength reflective film makes the sign more clear and visible, and use is safer.

[0017] The specific embodiments of the present application will be described below with reference to the accompanying drawings.
[0018] Referring to Figure 1 A waterproof reflective film, comprising a protective layer 2, a micro-prism layer 3, a reflective layer 31 and a base layer 4 which are compounded in sequence, wherein the surface of the protective layer 2 is coated with a waterproof layer 1, the waterproof layer 1 is provided with a plurality of convex ridges 11, and the convex ridges 11 and the convex ridges 11 form drainage grooves 10.
[0019] Referring to Figure 2 The cross section of the convex ridge 11 is a fan-shaped structure, and because the refractive index of the convex ridge 11 is greater than that of air, when external light enters the waterproof layer 1, the incident angle is greater than the exit angle, the light is refracted into the protective layer 2, and for the same reason, the light is refracted again into the micro-prism layer 3, the convex ridge 11 has a light condensing effect on external light, and then is emitted along the direction away from the vertical reflective film, and the high-strength reflective film makes the sign more clear and visible, and use is safer.
[0020] The edge of the protective layer 2, the micro-prism layer 3, the reflective layer 31 and the base layer 4 is provided with an edge sealing waterproof film.
[0021] The base layer 4 is composed of a back adhesive layer 41 and a release paper 42, and the back adhesive layer 41 is bonded to the reflective layer 31 away from the release paper 42.
[0022] The reflective layer 31 is an aluminum plating layer or a silver plating layer.
[0023] The protective layer 2 is made of PET material.
[0024] The protection layer 2 of the application is coated with a waterproof layer 1, the waterproof layer 1 prevents water from entering the reflective film, the waterproof layer 1 is provided with convex ridges 11, the convex ridges 11 directly form drainage grooves 10 with the convex ridges 11, the drainage grooves 10 guide surface rainwater, greatly reduce the water staying on the surface of the waterproof layer 1, and improve the waterproof effect.
