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

Embodiment Construction

[0008] The inkjet advertising light box cloth of the present invention comprises an ink-absorbing coating, a primer, a polyethylene woven cloth and a polyethylene coating layer. The ink-absorbing coating is composed of 40 parts of polyvinyl acetate emulsion with a solid content of 40%. Pure acrylic emulsion with 40% solid content, 6 parts calcium carbonate, 1.5 parts silica powder, 1.5 parts titanium dioxide, 0.2 parts foam inhibitor and defoamer, 0.15 parts wetting agent, 0.26 parts whitening agent, 0.32 parts thickening agent And ammonia water is prepared according to the weight ratio. The primer is made of polyurethane glue. The polyethylene coating layer is made of low-density high-pressure polyethylene.

[0009] In the present invention, the polyethylene plastic pellets are first cut into filaments and stretched into flat yarns to be woven into a plastic woven cloth; then the reverse side of the plastic woven cloth is coated, the front side is coated with a primer, and fina...

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 an outdoor large advertising light box cloth, 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 product, which is widely used in outdoor large-scale advertising. Such as roads, railways, streets, large advertisements on the floor, all made of outdoor inkjet light box cloth. The current "outdoor inkjet advertising light box cloth" is all made of PVC, that is, the warp-knitted net is made of polyester yarn, and the front and back are made of PVC leather by heat bonding. Although "PVC inkjet advertising light box cloth" has a simple process and low cost, it also has many fatal weaknesses: (1) It is not environmentally friendly. It will release HCl above 60°C, causing damage to the environment. (2) The printing effect is not good, and it is not compatible with solvent-based, eco-solvent-based and UV-cur...
