Embodiment 1
[0056] A glass wallpaper, the main body is composed of a protective film layer, an adhesive layer, a base material layer and a process layer, wherein the base material layer is made of a transparent plastic film material, generally a transparent medium-temperature to high-temperature PET film, according to actual needs such as fire prevention or It can be replaced with but not limited to transparent reinforced PVC film or PC, composite plastic film and other transparent plastic films, and materials such as explosion-proof film and heat insulation film can also be directly used. If PVC film is used, its process is preferably film made by casting method. The film is relatively thin and the water ripples are not obvious. Add stabilizers and other additives to increase its processing temperature. The material thickness of the substrate layer is between 4cm-35cmm, preferably 5-15cmm. The heat-resistant temperature of the material is above 120°C. The back of the material is coated wi...
Embodiment 2
[0067] The process layer is first printed with the above UV ink process and then combined with the powdering process. The steps are:
[0068] This method generally adopts the method of overprinting, and the material is made of transparent plastic film as the base material. The main UV ink process is partly packaged by screen printing, and the roll package is printed by a gravure printing machine, and transparent UV ink is printed by gravure printing or rotary screen printing; Transparent UV ink is mixed with pearl powder, glitter powder and other toners for printing; first print the color ink layer and then overprint the transparent UV ink layer in three ways to complete the above UV ink process.
[0069] Powdering process: the premise of powdering is to make a glue layer first. The glue is generally matte film UV ink, crystal UV ink, refraction UV ink p, but it can also be water-based glue such as glitter paste, sticky bead paste, EVA glue, etc. Or oily mucilage, depending on...
Embodiment 3
[0071] The process layer is first printed with the above UV ink process and then combined with the powder spraying process. The steps are:
[0072] In order to enhance the shimmering effect of glass wallpaper, it is usually necessary to add some glitter powder with a relatively large particle size. If it is mixed in the ink, whether it is silk screen printing or gravure printing, the mesh of the powder material with too large particle size is usually relatively small. , so the ink is thicker, the pattern is thicker, and the powder material is inside the ink, the flickering effect is not obvious, the following powder spraying process can be used to solve the problem.
[0073] First use the above UV ink process, and use screen printing or gravure printing to directly print transparent UV ink; transparent UV ink is mixed with pearl powder and other toner fillers for printing, but do not add glitter powder with a relatively large particle size; first print the color ink layer Then...
