[0036] A preparation process for spray-painted reflective film, comprising the steps of:
[0037] Step 1. Using the PET base film as a carrier, apply a modified ink-absorbing spray-painting layer 1 glue on the carrier with a comma blade coater, and dry it;
[0038] Step 2: Print the adhesive layer 2 glue on the modified ink-absorbing inkjet layer 1 with a micro-gravure printing machine, semi-dry, and stick the microprism crystal powder to the surface of the semi-dried adhesive layer 2 through a plant machine, after sticking Immediately vibrate the roller so that the plane of the microprism crystal powder faces the bonding layer 2, and then continue to dry, and the microprism crystal powder is partially embedded in the bonding layer 2;
[0039] Step 3: Use the PET release film as the carrier, and use a comma blade coater to coat the glue of the white backing layer 5 on the carrier, half-dry, stick the luminescent powder to the surface of the half-dried white backing layer 5 thr...
Embodiment 1
[0045] A preparation process for spray-painted reflective film, comprising the steps of:
[0046] Step 1. Use a PET base film with a thickness of 50 μm and a width of 1270 mm (requires a shrinkage rate of ≤0.2% at 180° C.) as a carrier, and use a comma blade coater to coat the modified ink-absorbing inkjet layer glue (PVC solution system glue, press In terms of mass percentage, it consists of the following components: 22% PVC powder, 50% THF solvent, 20% MIBK solvent, 6% plasticizer, 1% epoxy soybean oil, 0.5% graphene, 0.2% UV ultraviolet absorber, 0.2% light stabilizer, 0.1% viscosity stabilizer), setting knife edge 400μm, 60℃-140℃ oven gradient heating, speed 10m / min, winding tension 1.8KG, dry thickness 50±1μm, residual solvent ≤0.5 %, the coating is uniform in appearance, without bubbles and particles.

Abstract
The invention discloses an inkjet reflective film. The inkjet reflective film comprises a modified ink-absorption inkjet layer, a bonding layer, a micro-prism crystal powder layer, a glow powder layer, a white substrate layer, a removable adhesive layer, and a release paper layer; the bonding layer is arranged below the modified ion-absorption inkjet layer, and the micro-prism crystal powder layerand the glow powder layer are arranged at intervals; flat surfaces of the micro-prism crystal powder are upward and the tips are downwards, partial micro-prism crystal powder is embedded into a lowersurface of the bonding layer and partial micro-prism crystal powder is embedded into an upper surface of the white substrate layer; the removable adhesive layer is arranged below the white substratelayer, and the release paper layer is arranged below the removable adhesive layer. The invention further discloses a preparation process thereof. The inkjet reflective film disclosed by the inventionhas the night self-luminous double effect by utilizing a high-reflecting principle of the micro-prism crystal powder and combining the glow powder; the surface layer of the product disclosed by the invention is a good modified ink-absorption inkjet layer and is high in weather-resistant. The inkjet, the luminous and the reflecting three characteristic are perfectly fused in the product disclosed by the invention, and can be easily observed whether under a state of possessing a light source or the state without the light source.
Description
technical field [0001] The invention relates to the technical field of reflective materials, in particular to a spray-painted reflective film and a preparation process thereof. Background technique [0002] The traditional reflective film mostly adopts the reflective property of glass beads or the property of prism panel. Using the reflective properties of glass beads, its retroreflection coefficient is not high, which limits the basic performance of the product; using the properties of prism panels, the plane shape is formed into a closely arranged pyramid-shaped prism layer at one time, and the equipment requirements are high, and the production speed is up to 3m. / min. And generally only have reflective function, do not have luminous function, application is limited. [0003] Existing reflective film is mostly used in fields such as traffic signs, industrial safety signs, license plates, and is less used in outdoor advertisements. The reflective film used for outdoor a...
