In order to improve the production efficiency and reduce the production cost, the existing manufacturing process of the glass bead type reflective film is improved and upgraded, the glass bead layer and the focusing layer are directly subjected to a bead mixing process, namely, the glass beads and resin are directly mixed and then are coated and formed at one time, the process simplifies the interlayer structure of the traditional glass bead type reflective film, greatly improves the production efficiency of the reflective film and reduces the production cost.
However, many technical problems, such as the storage stability of the mixed solution during the coating process, also occur during the production of the glass bead-type reflective film by the mixed bead process. Because the specific gravity of the glass beads in the mixed solution is greatly higher than that of the resin, the glass beads with higher specific gravity are easy to precipitate and delaminate from the resin, so that the mixed solution is changed into an unstable turbid liquid, and finally, the number difference of the glass beads on the unit area of the coated product is huge, so that the consistency of the product is poor, defective products such as powder lines, flower spots and the like are easy to occur, and the performance of the product and the quality stability of mass production are influenced finally.
In addition, after the mixed liquid is coated into a wet coating with a certain thickness by a scraper of a coating device, the bubbles in the coating are difficult to remove because the bubbles are mixed in the wet coating and the coating is relatively thick, and the accumulated and pressed bubbles which cannot be discharged finally cause the bubble point defect of the product in the coating and also influence the retroreflection performance of the product. Meanwhile, the glass beads on the vertical section of the wet coating unit are randomly distributed in the matching liquid, if the glass beads with different heights cannot be settled to the same horizontal plane or more than 90% of the glass beads cannot be settled to the same horizontal plane, the injected light cannot be well focused on one surface, so that the retroreflection performance of the final product cannot meet the national regulation requirements, and the mass production and the sale cannot be carried out.
In view of the above problems, there is still a need to develop a bead mixing process and apparatus for producing the same to solve the problem of coating retroreflective sheeting.
