Method for making wallpaper from biomass material

Abstract

The invention relates to a production method of wallpaper, and provides a method for producing wallpaper from biomass materials. The method is simple and easy to implement, and is suitable for mass production and use. The laminated structure of the wallpaper prepared by the method is simple and has excellent flame retardancy Performance, non-toxic and smoke-free, environmental protection, biodegradable and other functions; including the following steps in turn: hemp stalk core fiber pretreatment → hemp stalk core fiber impregnation treatment → hemp stalk core fiber drying treatment → base paper preparation → surface layer Coating → drying, cooling → printing, softening, embossing and cutting packaging.

Description

technical field [0001] The invention relates to a method for producing wallpaper, in particular to a method for producing wallpaper from biomass materials. Background technique [0002] Wallpaper is a kind of specially processed paper used to decorate walls. It is widely used in the interior decoration of houses, offices, hotels, hotels, etc. It has been widely popularized in the world. With the continuous improvement of production technology, wallpaper's Manufacturing technology is constantly advancing. The current conventional wallpaper is made of wood pulp paper, with polyvinyl chloride (PVC) as the layer, and is made through printing, embossing, foaming and other processes. It has the characteristics of rich colors, diverse groups, fine texture, and easy construction.

[0003] However, due to the large amount of petrochemical raw materials such as PVC used in wallpaper materials, the anti-fog is easy to burn in the event of a fire, and releases a large amount of toxic fumes such as dioxin and hydrogen chloride, which poses a huge threat and hidden danger to the safety of residents' lives and property

At present, the common flame retardant wallpapers mostly use the method of adding flame retardants to the base paper, coating, and protective layer to achieve the purpose of flame retardant, but they usually have the following shortcomings: the durability of flame retardants is poor, and some inorganic flame retardants are easy to fall off. In addition, some organic flame retardants are volatile and invalid after long-term use; they are easy to absorb moisture, and the flame retardant and physical properties of paper decrease significantly after moisture absorption; the addition of flame retardants has different degrees of durability and printability of wallpaper. adverse effects of
