Description

Technical Field

[0001] The utility model relates to the technical field of reflective films, in particular to a reflective film with corrosion resistance and hydrolysis resistance. Background Technique

[0002] A reflective film is a retroreflective material that has been made into a film and can be directly applied. It is made by using glass bead technology, microprism technology, synthetic resin technology, film technology, coating technology, and microreplication technology. A reflective film is a retroreflective material that has been made into a film and can be directly applied, and it is also one of the most widely used retroreflective materials. Based on the basic structure of the retroreflective unit, it is sorted according to the retroreflective coefficient of the front photometric performance of the reflective film. However, considering the different processes of the reflective film, some are specifically designed to solve the non-front retroreflective brightness, and some take both aspects of performance into account. Due to its long history, various different manufacturers have made many kinds of reflective films by using different diameters, densities of lenses, and thicknesses of weather-resistant coatings during the long production process. For example, the super engineering grade reflective film is mainly based on the engineering grade reflective film, using higher quality glass beads and increasing the density of the glass beads to improve the brightness. The so-called economic grade reflective film is mainly produced in China and is basically achieved by reducing the number and density of lenses (glass beads) on the basis of the technology of the engineering grade reflective film. For these two kinds of reflective films, the economic grade reflective film cannot meet the needs of traffic safety in terms of its reflection ability and is more used in the commercial field. It is rarely included in the traffic safety light standard internationally. However, the corrosion resistance and hydrolysis resistance of some existing reflective films are generally average, which affects the service life of the reflective film.

[0003] For example, the publication number is: CN219811063U, a reflective film, which includes a PET surface layer, a PMMA layer is arranged on the upper plane of the PET surface layer, a glass microbead layer is embedded in the PMMA layer, the glass microbead layer includes glass microbeads evenly distributed in the PMMA layer, and adjacent glass microbeads are arranged at intervals. A hemispherical protrusion is formed on the upper plane of the PMMA layer, and the position and number of the hemispherical protrusions correspond to those of the glass microbeads one by one. An aluminized layer is arranged on the upper plane of the PMMA layer, and a pressure-sensitive adhesive layer is arranged on the upper plane of the aluminized layer; in the utility model, the glass microbead layer is embedded in the PMMA layer to form an integral structure. During production, only one layer of PMMA layer needs to be coated to simultaneously form the PMMA layer and the glass microbead layer. Compared with the prior art, the utility model has one less layer of PMMA layer, reduces the number of coating times and the process of laying glass microbeads, reduces the production material cost, equipment cost, and labor cost, simplifies the production process, and has the effect of reducing costs and increasing efficiency.
