Abstract

The invention discloses an environment-friendly waterborne polyurethane coating and wallpaper adopting the coating. The coating includes the following components in part by weight: 30-40 parts of diisocyanate, 6-10 parts of epoxidized soybean oil, 8-13 parts of dyhydroxy methyl propionic acid, 10-15 parts of dipropylene glycol, 8-12 parts of neopentyl glycol, 5-8 parts of organobentonite, 3-6 parts of ethidene diamine, 5-8 parts of ethylene glycol amine, 3-6 parts of acetic acid, 4-7 parts of cross-linking agent and 2-4 parts of catalyst. The wallpaper adopting the coating includes the following layers from bottom to top sequentially: a backing paper layer, a bonding layer, a primary layer, the environment-friendly waterborne polyurethane coating and a static flocking layer. According to the invention, the environment-friendly waterborne polyurethane coating and the static flocking layer are adopted, the wallpaper has the advantages of alkali, ethyl alcohol, water and abrasion resistance, better glossiness and the like, and the static flocking layer enables the stereoscopic effect of the wallpaper to be more obvious, and improves the attractiveness of the wallpaper.

Description

【Technical field】 [0001] The invention relates to the technical field of decorative materials, especially the technical field of wallpaper. 【Background technique】 [0002] At present, most domestic wallpaper materials use various solvent-based chemical additives. In the production process, a large amount of toluene, cyclohexanone, acetone, gasoline, and butyl acetate are used as solvents, and additives such as heavy metal salts are added. These organic solvents In the long-term after the production, construction and film formation of additives and additives, substances such as organic compounds (VOC) and carcinogens that infringe human nerves, mucous membranes, skin and liver organs will be continuously released to the surrounding environment, causing serious pollution to the environment. my country's 10 national standards for the limitation of harmful substances in interior decoration and decoration materials have been officially implemented on January 1, 2002. Since July 1, ...
