Description

Technical Field

[0001] The invention relates to the technical field of reflective films, in particular to a reflective film production process using EVU glue spraying. Background Art

[0002] Reflective film is a kind of retro-reflective material that has been made into a film and can be directly applied. Its working principle is based on the principle of optical reflection. When light shines on the reflective film, it can reflect the light back to the light source through the special internal structure (such as glass beads or microprisms), thereby providing clear visual cues in dark environments and effectively reducing the risk of accidents. It is made using glass bead technology, microprism technology, synthetic resin technology, etc., and can efficiently reflect light back to the light source. The colors of reflective film are diverse, including white, yellow, red, green, blue, brown, orange, fluorescent yellow, fluorescent orange, fluorescent yellow-green, etc., as well as foreign fluorescent red and fluorescent pink, etc. Depending on the type, the service life of the reflective film can range from a few years to more than ten years, and it can maintain stable reflective performance under harsh climatic conditions. In the field of transportation, reflective film is widely used in the production of traffic signs, road markings, traffic signs and vehicle identification to improve night visibility and traffic safety. In addition, reflective film also plays an important role in construction, advertising, industry, outdoor sports, electronic products, agriculture and environmental protection.

[0003] There is a heat-resistant reflective film production process (Announcement No.: CN114801267B). A drying, cooling and heating test process is set at the back end of the process to detect the heat resistance of the reflective film. At the same time, the rapid heating after cooling causes the reflective film to undergo a large thermal change, which can also timely discover tiny cracks or defects in the production process. The heat resistance test can also enlarge the defects, making them easier to be discovered, thereby improving the yield and reliability of the factory products. At the same time, since the products produced by this process are used under heat-resistant conditions, the safety of users is indirectly improved.

[0004] The above existing devices can improve the heat resistance of the reflective film, and indirectly improve the safety of the user. However, the reflectivity of the reflective film has always been the breakthrough focus of the reflective film, and improving the reflectivity of the reflective film also greatly improves the use effect of the reflective film. Although the above existing devices can improve the heat resistance of the reflective film, the improvement of the reflectivity of the reflective film still needs to be improved.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] In order to overcome the technical defects of the prior art, the present invention provides a reflective film production process using EVU glue spraying, which can achieve the purpose of improving the reflectivity of the reflective film.

[0007] The technical solution adopted by the present invention is: the reflective film includes a protective film, a reflective layer, a focusing layer, a bearing layer, an adhesive layer and a peeling layer, the protective film is closely arranged on the upper surface of the reflective layer, the reflective layer is composed of tiny glass beads, the reflective layer is bonded to the upper surface of the focusing layer, the focusing layer is composed of a tiny convex lens structure, the focusing layer is located on the upper surface of the bearing layer, the adhesive layer is closely arranged on the lower surface of the bearing layer, and the peeling layer is located on the lower surface of the adhesive layer. The manufacturing process includes the following steps: S1: Preparation of materials for each layer: Prepare the materials for each layer of the reflective film and ensure that the materials are in a dust-free and clean environment; S2: Laying the bearing layer: The staff places the bearing layer on the conveying roller, and then transports the bearing layer to the laying area through the conveying roller, applies glue to the bearing layer, and then lays the micro-convex lens structure on the upper surface of the bearing layer, and then presses and fits the structure composed of the micro-convex lens structure and the bearing layer; S3: Laying the reflective layer: Place the bearing layer with the micro-convex lens structure on the conveyor roller, transport the bearing layer to the laying area through the rotation of the conveyor roller, and evenly lay the glass beads on the base film using the storage barrel and the filter plate. The use of the vibrator can help the glass beads to be spread more evenly on the bearing layer to avoid accumulation or gaps. By adjusting the parameters of the laying equipment, the thickness of the laid micro-glass beads is 0.05mm-0.1mm. After the laying is completed, use the bead planting roller and other equipment to compact the micro-glass beads to ensure that they are closely combined with the bearing layer. S4: Glue coating: The worker uses a coating machine to evenly coat the EVU glue on one side of the peeling layer; S5: Pressing and laminating: The peeling layer coated with glue in step S2 is pressed and laminated with the base film constituting the bearing layer by a pressing roller, and then dried and cured, and then rolled up.

[0008] Preferably, in order to protect the reflective film through the protective film and provide efficient protection while ensuring light transmittance, the protective film is used to protect the reflective layer and the adhesive layer from dust, the protective film is composed of a transparent resin, and the thickness of the protective film is 0.08mm-0.15mm.

[0009] Preferably, in order to provide support and toughness to the reflective film through the bearing layer and effectively support the reflective layer, the bearing layer is composed of two layers of PT material base film, the bearing layer is used to support the reflective layer, and the thickness of the PT material base film is 0.05-0.1mm.

[0010] Preferably, in order to gather light through the tiny convex lens structure laid flat on the supporting layer and then reflect it through the reflective layer to improve the reflective effect of the reflective film, the focusing layer is used to gather light, and the thickness of the tiny convex lens structure in the focusing layer is 0.05mm-0.1mm.

[0011] Preferably, in order to enable the reflective film to be pasted to different positions, the adhesive layer is made of epoxy resin, and the thickness of the adhesive layer is 0.02 mm-0.05 mm.

[0012] Preferably, in order to facilitate the user to easily separate the peeling layer from the adhesive layer, and the thick paper does not adhere to the EVU glue, the peeling layer is made of thick paper, and the thickness of the thick paper is 0.05mm-0.1mm.

[0013] Preferably, in order to prevent the VU glue from being too thick, the glue of the adhesive layer is EVU glue, and the coating thickness of the EVU glue is 0.02mm-0.05mm.

[0014] The beneficial effects of the present invention are as follows: the present invention can greatly improve the reflectivity of the reflective film by adjusting the thickness of the tiny glass beads in the reflective layer, thereby improving the reflective efficiency of the reflective film. At the same time, the provision of the adhesive layer and the peeling layer can greatly facilitate the user to install the reflective film. The reflective film has a significant effect of improving the reflectivity and has obvious improvements. BRIEF DESCRIPTION OF THE DRAWINGS
