Abstract

The invention discloses a high-weatherability water-borne printing ink for PVC wallpaper. The printing ink comprises the following components by mass: 20 to 50% of waterborne color paste, 30 to 60% of waterborne resin emulsion, 1 to 5% of a wear-resistant scraping-resistant agent, 0.5 to 3% of a film-forming aid, 0.2 to 2% of a leveling agent, 0.1 to 0.5% of an antifoaming agent, 0.1% of antiseptic and 5 to 20% of purified water. According to the invention, modified magnesium-aluminum hydrotalcite capable of effectively absorbing ultraviolet light and infrared light in sunlightis introduced, so the ageing speed of the printing ink is decreased, weatherability of a printed pattern of the PVC wallpaper is improved, and the service life of the wallpaper is prolonged; meanwhile, high-weather-resistance-grade pigment capable of tolerating waterborne resin emulsion with a high temperature of more than 200 DEG C is utilized, so the printing ink for the PVC wallpaper has substantially improved temperature resistance and weatherability; and even under the conditions of high temperature and solarization, the printing ink can well maintain original characteristics and perfectly meets high-standard requirements on waterborne printing ink for the PVC wallpaper.

Description

technical field [0001] The invention relates to a highly weather-resistant water-based ink for PVC wallpaper and a preparation method thereof, belonging to the technical field of water-based inks. Background technique [0002] At present, the wallpapers produced in our country can be divided into paper-based paper wallpapers, PVC wallpapers, fabric wallpapers, natural material wallpapers, sand wallpapers, diatomite wallpapers, and non-woven wallpapers according to materials. PVC wallpaper uses paper as the base material and PVC as the surface layer, and the PVC surface layer is covered and sealed, and then embossed and printed to decorate and beautify the PVC wallpaper. Water-based ink uses water as a solvent, and other organic solvents are added in a small amount or even not added, which not only reduces the physical damage caused by solvent volatilization during the printing process to on-site printing operators, but also makes it basically free of residual solvent volatil...
