Novel spray-painted advertisement lamp box fabric

Abstract

The invention relates to novel spray-painted advertisement lamp box fabric. The novel spray-painted advertisement lamp box fabric comprises a blended modified plastic laminated film layer (1), low-pressure high-density polyethylene woven fabric (2) and a high-pressure low-density polyethylene laminated film layer (3), wherein the blended modified plastic laminated film layer (1) is arranged on the front surface of the low-pressure high-density polyethylene woven fabric (2), and the high-pressure low-density polyethylene laminated film layer (3) is arranged on the reverse surface. The novel spray-painted advertisement lamp box fabric disclosed by the invention has the advantages of good environment-friendly performance, low temperature resistance and printing effect, can be compatible with four types of ink printing, namely solvent type, weak solvent type, UV (ultraviolet) curing type and Latex type, and can withstand the expose to sun and rain.

Description

technical field [0001] The invention relates to a cloth for a large outdoor advertising light box, in particular to a novel 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, widely used in large outdoor advertisements. For example, next to roads and railways, the large 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 material, that is, it is made of polyester thread warp-knitted net, and the front and back are heat-sealed 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 HCI when it is above 60°C, and cause damage to the environment. ⑵The printing effect is not good, and it is not compatible with solvent-bas...

AI Technical Summary

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 HCI when it is above 60°C, and cause damage to the environment

⑵The printing effect is not good, and it is not compatible with solvent-based, weak-solvent, UV-curable and Latex inks

⑶ heavy weight (ordinary between 400 ~ 600g / ㎡), poor low temperature resistance (-20 ℃), so it can not resist harsh weather conditions outdoors

⑷ Printing ink absorption and drying speed is not ideal

The lamp cloth of this coating layer has certain defects: (1) Two coating processes (coating primer and ink-absorbing coating) are added in the production, resulting in a decrease in yield

⑵The adhesion between the coating layer and the lamp cloth is not enough (although the primer has been applied), it cannot withstand the sun and rain, and it will often peel off after a long time, that is, if it is outdoors for more than half a year

The advertising screen has lumps and peeling off, which is not beautiful
