Abstract

The invention provides a silica gel reflective lettering film decoration forming method which comprises the following steps: (1) taking a PET coiled material, coating the surface of the PET coiled material with a release surface and an anilox roller with 200 meshes, and coating and baking for 3-5 minutes at the temperature of 80-120 DEG C; 2) scraping a PP resin layer on the surface of the releasesurface after the step 1) is completed; 3) implanting at least one glass bead into the surface layer of the PP resin layer after the step 2) is completed; (4) flattening the glass beads by using a silica gel roller at the temperature of 140-170 DEG C after the step (3) is finished, and melting the glass beads to 1/4-1/2 of the thickness of PP resin; (5) blade-coating an environment-friendly silica gel layer on the glass beads; (6) roller-coating an environment-friendly resin layer on the surface of the environment-friendly silica gel layer; and (8) slitting the material according to the specification, trimming and confirming the product quality. According to the invention, at least one glass bead is implanted into the surface layer of the PP resin layer, and the glass bead is melted to 1/3 of the thickness of the PP resin layer so that the reflective bead does not fall off, and the durability of the reflective effect is ensured.
