Problems solved by technology

Most of the large billboards made of advertising cloth are located in the open outdoors, such as around the highway. Due to the long-term exposure to wind and sun, especially in summer, the large outdoor billboards are easily damaged, especially The advertising cloth on the billboard is easy to be corroded under the sunlight, especially the ultraviolet radiation, which may cause the advertisement content to fade, or cause damage to the advertising cloth. Since the large billboard is located in the suburbs and has a large It is very difficult and costly to replace, so there is a huge market demand for advertising cloth that is more resistant to sunlight, especially ultraviolet rays

Abstract

The invention discloses an advertising cloth with photocorrosion resistance. The advertising cloth is composed of a grid cloth, a PVC laminating layer and a photocorrosion resisting layer, wherein the PVC laminating layer is produced from PVC paste resin, an environmentally-friendly plasticizer, a stabilizer, a filler, a flame retardant, a mildew inhibitor, an antioxidant and an adhesive; and the photocorrosion resisting layer is composed of micro-nano zinc oxide fibers. The invention also discloses a processing method of the advertising cloth with photocorrosion resistance. The advertising cloth has good photocorrosion resistance, can reflect a large amount of visible lights, and also can shield ultraviolet rays; and the above production method of the advertising cloth has the advantages of simplicity, fastness, good effect, realization of production by using present devices, and small difficulty in industry reconstruction.

Description

technical field [0001] The invention relates to the technical field of light box advertising cloth, in particular to an advertising cloth with anti-light corrosion performance and a processing method thereof. Background technique [0002] With the continuous development of the commodity economy, the advertising decoration industry is also booming, and the use of advertising cloth is also increasing. The traditional advertising department is mainly made of two layers of polyethylene and one layer of high-strength grid cloth and three layers of thermal lamination. Most of the large billboards made of advertising cloth are located in open outdoor places, such as around the expressway. Due to long-term exposure to wind and sun, especially in summer, the large outdoor billboards are easily damaged, especially The advertising cloth on the billboard is easy to be corroded under the sunlight, especially the ultraviolet radiation, which may cause the advertisement content to fade,...
