Background
Wallpaper, also called wall paper, is an interior decoration material with quite wide application. The wallpaper has the characteristics of various colors, rich patterns, luxury, safety, environmental protection, convenient construction, proper price and the like which are incomparable with various other interior decoration materials, so the wallpaper is popularized in developed countries and regions such as Europe, America, Japan and the like to a considerable extent. The wallpaper can be classified into various types, such as coated wallpaper, embossed wallpaper, and the like. The base paper is usually produced from bleached chemical wood pulp, and then is processed through different procedures, such as coating, printing, embossing or surface plastic coating, and finally is cut and packaged for delivery. Because of having certain intensity, toughness, beautiful appearance and good water resistance, the coating is widely used for indoor decoration of houses, offices, hotels, and the like.
Along with the improvement of the performance (including waterproofness, toughness, strength and the like) of the wallpaper, people also put forward higher requirements on the aspects of patterns, colors and the like of the wallpaper, the ornamental performance of the wallpaper gradually becomes an important index for measuring the value of the wallpaper, at present, the texture on the surface of the wallpaper manufactured by foaming slurry is realized by a high-temperature hot printing mode, the texture formed by the mode is also called embossing, the shape of the pattern expressed in the embossing is single, and the wallpaper pressed by the same embossing roller is consistent, so that the current wallpaper products rarely meet the texture requirements of unique shape and strong variability, in addition, as the embossing comes from the printing of the foaming slurry layer, the printing process requirements are higher, especially the control on the thickness of the foaming slurry layer and the fine control on the operation of the embossing roller are required, therefore, the traditional wallpaper is not only complicated to manufacture, the difficulty is high, the monotonous embossing pattern cannot be matched with the modern aesthetic concept with diversified requirements and strong appreciation, and the products selectable by consumers are not abundant.
Aiming at the problems, the Chinese patent ZL: 201520268214.7 discloses a wallpaper with foaming suppression; comprises a bottom layer, and a pre-coating liquid layer, a foaming slurry layer and a foaming-inhibiting slurry layer which are sequentially compounded on the bottom layer; the foaming paste layer and the foaming-inhibiting paste layer coated on the foaming paste layer form the texture of the wallpaper surface together.
