Embodiment 1
[0034] First implant a number of glass beads 1 with a high refractive index on the surface of the thermoplastic PE film material, so that the glass beads 1 are distributed on the surface of the thermoplastic PE film material in an orderly or disorderly manner, by controlling the temperature between 100°C and 110°C To control its sedimentation depth, the glass microspheres 1 are partially embedded in the PE film material to form a glass microsphere layer, and the mosaic depth is 30% of the thickness of the glass microspheres 1. The surface of the bead 1 side is coated, and an opaque gray reflective layer 2 of aluminum material is formed on the surface, with a thickness of 150 angstroms. The color adhesive layer 3 is formed by coating the surface with common colored polyester material, and then the hot melt adhesive layer 5 is glued on the surface of the color adhesive layer 3; A white base layer is compounded between the adhesive layers 5; after cooling, the thermoplastic PE fi...
Embodiment 2
[0036] First implant a number of glass beads 1 with a high refractive index on the surface of the thermoplastic PE film material, so that the glass beads 1 are distributed on the surface of the thermoplastic PE film material in an orderly or disorderly manner, by controlling the temperature between 100°C and 110°C To control its sedimentation depth, the glass beads 1 are partially embedded in the PE film material to form a glass bead layer 1, and the inlay depth is 50% of the thickness of the glass beads 1, which is equivalent to exposing half of the glass beads 1 to the outside , then, carry out coating treatment on the surface of the above-mentioned implanted glass microsphere 1 side that is exposed to the outside, and form an opaque gray reflective layer 2 of one deck aluminum material on the surface, so that the thickness of the gray reflective layer 2 formed is 100 angstroms, such as by vacuum coating, and then on the surface of the gray reflective layer 2, a colored adhes...
Embodiment 3
[0038] The specific manufacturing method of the two-color thermal film of this embodiment is the same as that of Embodiment 2, the only difference is that the thickness of the formed gray reflective layer 2 is 200 angstroms, and this embodiment also includes the use of the same laser cutting treatment conditions to make the glass micro The gray reflective layer 2 below the beads 1 is also partially cut to form partial light transmission. The size of the light transmission area can be properly adjusted according to actual needs, so that the gray reflective layer 2 below the glass beads 1 can reflect light locally and partially Light transmission characteristics, showing a two-color effect of gray reflective color and colorful color effect at the bottom, to obtain a corresponding two-color thermal film.
