Problems solved by technology

Although "PVC inkjet advertising light box cloth" is simple in process and low in cost, it also has many fatal weaknesses: (1) It is not environmentally friendly, it will release HCl when it is above 60°C, and cause damage to the environment
(2) The printing effect is not good, and it is not compatible with solvent-based, weak-solvent and UV-curable inks.
(3) Mass weight (ordinary is 400-600g / m 2 between), poor low temperature resistance (-20°C), so it cannot resist harsh weather conditions outdoors
(4) Printing ink absorption and drying speed is not ideal

Abstract

The invention discloses spray-painting advertising lamp box cloth comprising an ink-absorbing coating, a primer coating, polyethylene woven cloth and a polyethylene laminated layer, wherein the ink-absorbing coating is formed by compounding 40 parts by weight of polyvinyl acetate emulsions with the solid content of 40%, 40 parts by weight of pure acrylic emulsion with the solid content of 40%, 6 parts by weight of calcium carbonate, 1.5 parts by weight of silicon dioxide powder, 1.5 parts by weight of titanium white, 0.2 part by weight of anti-foaming agent, 0.15 part by weight of wetting agents, 0.26 part by weight of brighteners, 0.32 part by weight of thickeners and ammonia water. By adopting the technical scheme, the spray-painting advertising lamp box cloth can be compatible to solvent type ink printing, mild solvent type ink printing and UV (Ultraviolet) solidification type ink printing and has the advantages of high print resolution which reaches 1440 dpi, high printing and drying speed and color density, good color rendition, environmental protection, no pollution and reproducibility.

Description

technical field [0001] The invention relates to a light box cloth for outdoor large-scale advertising, in particular to an inkjet advertising light box cloth. Background technique [0002] In the field of advertising, "outdoor inkjet advertising light box cloth" is the most widely used commodity, which is widely used in large-scale outdoor advertising. Such as highways, railways, streets, large-scale advertisements on the floor are all made of outdoor inkjet light box cloth. The current "outdoor inkjet advertising light box cloth" is all made of PVC, that is, it is made of warp knitted mesh with silk yarn, and the front and back sides are heat-bonded with PVC skin. Although "PVC inkjet advertising light box cloth" is simple in process and low in cost, it also has many fatal weaknesses: (1) It is not environmentally friendly, it will release HCl above 60 ℃, causing damage to the environment. (2) The printing effect is not good, and it is not compatible with solvent-based, w...
