Embodiment 1
[0027] Such as figure 1 Shown, a kind of lens embedding type reflective film, it comprises facial film 1, planting bead layer 2, aluminized layer 4, adhesive back layer 5 and backing paper 6, be coated with planting bead layer 2 on the surface of film film 1, planting bead layer An aluminum-plated layer 4 is arranged between the layer 2 and the adhesive layer 5, and a backing paper 6 is arranged below the adhesive layer 5, which also includes glass microspheres 3 and a focusing layer 7, and the glass microspheres 3 are embedded inside the bead-planting layer 2, A focusing layer 7 is also provided between the bead-planting layer 2 and the aluminum-coated layer 4 , the particle diameter of the glass microspheres 3 ranges from 15 μm to 115 μm, and the particle diameter difference of the glass microspheres 3 is 5 μm to 15 μm.
[0028] Such as figure 2 As shown, the distance b at which the lower surface of the glass microsphere 3 sinks into the surface of the bead-planting layer ...
Embodiment 2
[0038] Its structure is with embodiment 1.
[0039] A bead planting process of a lens-embedded reflective film, which comprises the following steps:
[0040] S1. Screening glass microbeads 3: selecting glass microbeads 3 with a refractive index of 2.05, an average particle diameter of 65 μm, and a particle diameter difference of 10 μm;
[0041] S2, uniform mixing: mix the bead-planting resin and the glass beads 3 obtained in step S1 evenly, and the solid content of the resin and the glass beads are in a weight ratio of 1:4;
[0042] S3, bead planting: set the bead planting gap on the scraper coater, the gap is 135 μm, evenly coat the bead planting resin and glass microsphere 3 mixture obtained in step S2 on the mask 1, and the glass microbeads 3 fall into the bead planting The distance b on the surface of layer 2 is 3 μm, and it is baked and cured at a temperature of 105 ° C through an oven;
[0043] S4. Coating the focusing layer 7: after the bead-planting resin is dried, a...
