Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of white board paper, in particular to a low-quantity high-strength coated white board paper. Background Art
[0002] Whiteboard is a kind of cardboard with a white and smooth front and a gray back. It is mainly used for single-sided color printing to make paper boxes for packaging, or for design and handicrafts. Whiteboard is divided into two types: printing-specific and stationery. The former is mainly used for printing and making packaging boxes, while the latter is a stack of hanging drawings suitable for seminars, workshops, meetings and other occasions.
[0003] Currently, low-weight white paper has a low weight and thus a poor strength, and is easily damaged during use, which affects the use effect. Therefore, we propose a low-weight high-strength coated white paper. Utility Model Content
[0004] The purpose of the utility model is to provide a low-weight, high-strength coated white board paper, which can improve the strength of the low-weight white board paper and has a buffering property to prevent it from being easily damaged during use. At the same time, it can utilize recycled waste paper, which is beneficial to saving and environmental protection. It solves the problem that the current low-weight white board paper has a low weight and thus has poor strength, is easily damaged during use, and affects the use effect.
[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a low-weight, high-strength coated whiteboard paper, comprising a coating layer, a short-fiber pulp face sheet layer and a long-fiber pulp corrugated core layer, the upper surface and surface of the long-fiber pulp corrugated core layer are both provided with long-fiber pulp board layers, and the outer surfaces of the two long-fiber pulp board layers are respectively provided with a short-fiber pulp face sheet layer and a waste pulp back sheet layer on the side facing away from the long-fiber pulp corrugated core layer.
[0006] Preferably, a coating layer is provided on the upper surface of the short fiber pulp panel layer.
[0007] Preferably, anti-mildew particles are provided inside the short fiber pulp panel layer.
[0008] Preferably, a wear-resistant layer is provided on the lower surface of the waste paper pulp backboard layer.
[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0010] 1. The utility model achieves the effect of improving the strength of low-weight white paperboard by arranging a long-fiber pulp corrugated core layer, a long-fiber pulp board layer, a short-fiber pulp face plate layer and a waste pulp back plate layer, so as to improve the strength of the low-weight white paperboard and have cushioning properties to prevent it from being easily damaged during use. At the same time, recycled waste paper is utilized, which is beneficial to saving and environmental protection. The long-fiber pulp corrugated core layer and the two long-fiber pulp board layers constitute the core of the white paperboard. Due to the presence of the corrugated structure, the weight of the board core is greatly reduced, the weight of the white paperboard is reduced, and the white paperboard has certain cushioning properties. Due to the long-fiber pulp structure, the entire board core has high strength and has better resistance to tearing and folding. The board core, short-fiber pulp face plate layer and waste pulp back plate layer form the white paperboard. The short fiber structure in the short-fiber pulp face plate layer makes the surface layer of the white paperboard more delicate and convenient for printing and writing. The waste pulp back plate layer is produced by recycled paper, which is beneficial to energy saving and environmental protection.
[0011] 2. The utility model can prevent the short fiber pulp panel layer from getting moldy by providing anti-mildew particles, which would affect the viewing of graphic information on the surface of the short fiber pulp panel layer.
[0012] 3. The utility model can improve the surface wear resistance of the waste paper pulp backing layer by providing a wear-resistant layer. At the same time, the wear-resistant layer also plays a waterproof role, preventing water vapor from entering the interior of the waste paper pulp backing layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.
[0017] like Figure 1 and Figure 2 As shown, the utility model proposes a low-weight, high-strength coated whiteboard paper, which includes a coating layer 1, a short-fiber pulp surface layer 2 and a long-fiber pulp corrugated core layer 4. The long-fiber pulp corrugated core layer 4 is provided with a long-fiber pulp board layer 3 on the upper surface and the surface. The long-fiber pulp corrugated core layer 4 and the two long-fiber pulp board layers 3 constitute the core of the whiteboard paper.
[0018] A short fiber pulp panel layer 2 and a waste paper pulp backboard layer 5 are respectively provided on the side of the outer surface of the two long fiber pulp board layers 3 away from the long fiber pulp corrugated core layer 4. The board core, the short fiber pulp panel layer 2 and the waste paper pulp backboard layer 5 are composed of layers of white paper. A coating layer 1 is provided on the upper surface of the short fiber pulp panel layer 2. The coating layer 1 is a white paint used for writing or printing text and pattern information. Anti-mildew particles 7 are provided inside the short fiber pulp panel layer 2. The anti-mildew particles 7 can prevent the short fiber pulp panel layer 2 from moldy and affect the viewing of the graphic information on the surface of the short fiber pulp panel layer 2. A wear-resistant layer 6 is provided on the lower surface of the waste paper pulp backboard layer 5. The wear-resistant layer 6 can improve the surface wear resistance of the waste paper pulp backboard layer 5. At the same time, the wear-resistant layer 6 also plays a waterproof role to prevent water vapor from entering the interior of the waste paper pulp backboard layer 5.
[0019] In this embodiment, the long fiber pulp corrugated core layer 4 and the two long fiber pulp board layers 3 constitute the core of the white board paper. Due to the presence of the corrugated structure, the weight of the board core is greatly reduced, the quantitative white board paper is reduced, and the white board paper also has certain buffering properties. Due to the long fiber pulp structure, the entire board core has high strength and has better resistance to tearing and folding. The board core, short fiber pulp panel layer 2 and waste pulp backboard layer 5 form the white board paper. The short fiber structure in the short fiber pulp panel layer 2 makes the surface layer of the white board paper more delicate and convenient for printing and writing. The waste pulp backboard layer 5 is produced from recycled paper, which is beneficial to energy saving and environmental protection.
[0020] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
