Abstract

The invention discloses formaldehyde-scavenging wallpaper and a production method thereof and belongs to the technical field of decoration materials. The formaldehyde-scavenging wallpaper comprises a bottom layer (1), a decoration layer (2) and an absorbing layer (3) from bottom to top and is formed by means of printing and stacking layer upon layer by a multicolour press, wherein the bottom layer (1) is non-woven fabric, the decoration layer (2) is a multicolor printing layer, and the absorbing layer (3) is made of materials with a formaldehyde adsorbing function. The formaldehyde-scavenging wallpaper has the advantages that the formaldehyde-scavenging wallpaper is capable of adsorbing and decomposing formaldehyde in the environment truly after being stuck on a wall, and recurrence is avoided; through testing of National Quality Supervision and Testing Center for Environment-Friendly products, formaldehyde scavenging ratio in 24 hours is 81%; through testing of (National) Technical Supervision and Research Center of the Building Materials Industry, the formaldehyde-scavenging wallpaper conforms to technical specifications of 'class-I materials' in JC / T1074-2008, and formaldehyde scavenging ratio is up to 80.6% (formaldehyde scavenging ratio is not less than 75% according to standard requirements of the class-I materials).

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to a formaldehyde-removing wallpaper and a preparation method thereof. Background technique [0002] Wallpaper is a widely used interior decoration material, because wallpaper is colorful, convenient for construction, cheap and many other characteristics that other interior decoration materials cannot match. Therefore, Europe, America, Southeast Asia, South Korea and other developed countries and regions have been popularized to a considerable extent. With the improvement of people's living standards in our country, the number of consumers has greatly increased. There are many types of wallpaper. Usually, wood pulp is used to produce base paper, which is then processed through different processes, such as coating, printing, embossing or surface coating, and finally cut and packaged before leaving the factory. Because it has a certain strength, beautiful appearance and ...
