Embodiment 1
[0034] A kind of production technology of environment-friendly crystal epoxy wall sticker, concrete steps are as follows:
[0035] (1) Cut the base material to the required size; wherein, the structure of the base material is as follows figure 1 As shown, it consists of a release paper layer 1, a self-adhesive layer 2 and a PET material layer 3, and the thickness of the PET material layer is 1mm;
[0036] (2) According to the designed pattern, the pattern layer is printed with ink on the PET material layer of the base material, and the ink printing adopts Toyo UV ink;
[0037] (3) Use a screen printing machine to print SQ-1536B water-based varnish on the pattern layer to form a water-based varnish layer. After printing, dry it at 90°C for 15 minutes;
[0038] (4) Make a 300-mesh barrier oil screen plate according to the pattern, use the barrier oil screen plate to print PU-1536B water-based barrier oil around the pattern, wrap the pattern, and dry it at 90°C for 15 minutes af...
Embodiment 2
[0041] A kind of production technology of environment-friendly crystal epoxy wall sticker, concrete steps are as follows:
[0042] (1) with the step (1) of embodiment 1;
[0043] (2) with the step (2) of embodiment 1;
[0044] (3) Similar to step (3) of Example 1, the only difference is that the drying temperature of this step is 100°C, and the drying time is 10min;
[0045] (4) Similar to step (4) of Example 1, the only difference is that the drying temperature of this step is 100°C, and the drying time is 10min;
[0046] (5) Heat the SQ-1440B high-gloss water-based PU glue to 40°C with the help of a glue dispenser, and then combine the mold to drop the glue into the pattern area. After the glue is dispensed, place it in an environment with a temperature of 85°C and a humidity of 35%. Let stand for 2 minutes, then dry at 100°C for 10 minutes to solidify the glue to form a crystal glue layer with a thickness of 1.5 mm, take it out and let it cool naturally, to obtain the env...
Embodiment 3
[0048] A kind of production technology of environment-friendly crystal epoxy wall sticker, concrete steps are as follows:
[0049] (1) with the step (1) of embodiment 1;
[0050] (2) with the step (2) of embodiment 1;
[0051] (3) Similar to step (3) of Example 1, the only difference is that the drying temperature of this step is 95°C, and the drying time is 12min;
[0052] (4) Similar to step (4) of Example 1, the only difference is that the drying temperature of this step is 95°C, and the drying time is 12min;
[0053] (5) Heat the PU-109 matte water-based PU glue to 35°C with the aid of a glue dispenser, and then combine the mold to drop the glue into the pattern area. After the glue is dispensed, place it in an environment with a temperature of 85°C and a humidity of 30%. Let it stand in the middle for 2 minutes, then dry it at 95°C for 12 minutes to solidify the glue and form a crystal glue layer with a thickness of 1.5mm, take it out and let it cool naturally to obtain...
