[0009] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0010] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The meaning of "several" is one or more, unless otherwise clearly and specifically defined.
[0011] At present, the book paper and examination paper we use are more concerned with the visual experience of the paper, and there is not much research on the touch, etc., and the loss of paper after use is not taken seriously. However, book paper and examination paper are in direct contact with the skin at a high frequency. Due to the frequent flipping of the paper, the sweat secreted by the human body will cause damage to the surface of the paper, which will directly affect the writing effect and shelf life of the paper.
[0012] In view of the above problems, the embodiments of the present invention provide a cooling paper to reduce the sweat secretion of the human body, thereby improving the writing effect of the paper and extending the shelf life of the paper. Figure 1 The schematic diagram of the structure of the paperboard provided by the embodiment of the utility model is shown. Figure 1 As shown, the cooling paper includes: a paper base 100, the paper base has a first surface and a second surface relative to each other, and in addition, the cooling paper also includes a facial coating structure 200 and a bottom coating structure 300, wherein the facial coating structure 200 is arranged on the first surface, and the bottom coating structure 300 is arranged on the second surface, and the facial coating structure 200 and the bottom coating structure 300 have at least a cooling layer 340; wherein the bottom coating structure 300 includes a flame retardant layer 310 and a waterproof layer 320, and the flame retardant layer 310, the waterproof layer 320 and the cooling layer 340 are sequentially distributed along the direction close to the second surface.
[0013] It can be understood that the utility model provides a facial coating structure including at least a cool layer on the first surface of the paper base, so that when the human body contacts the cool paper, the heat on the skin surface is quickly lost, and there is a cool touch, which is conducive to improving the comfort of paper use. At the same time, when the human body contacts the facial coating structure including the cool layer, the cool touch can reduce the sweat secretion of the human body, thereby reducing the probability of the paper being damaged due to sweat soaking, which is conducive to improving the writing effect of the paper and extending the shelf life of the paper.
[0014] At the same time, in the utility model, by providing a flame retardant layer, a waterproof layer and a cool layer on the bottom coating structure, the problem of easy ignition of jammed paper and fire can be solved on the basis of improving the comfort of paper use, thereby improving the safety of cool paper during use. Not only that, it can also improve the resistance of cool paper to water penetration, further improve the writing effect of paper, and extend the shelf life of paper. It should be understood that in order to enhance the cool touch of cool paper, further reduce the amount of sweat secreted by the human body, improve the writing effect of paper, and extend the shelf life of paper, multiple cool layers can be provided in the bottom coating structure, which is not limited here.
[0015] In an optional manner, the cooling layer in the embodiment of the utility model is a cooling microcapsule layer, which includes a gridded support layer and cooling microcapsules arranged in each grid in the gridded support layer. In the utility model, by arranging a gridded support layer in the cooling layer, the cooling microcapsules of the cooling paper can be evenly filled, avoiding uneven filling of the cooling microcapsules and affecting the cooling effect of the cooling paper. In addition, arranging a gridded support layer in the cooling layer can also protect the cooling microcapsules, reducing the probability of the cooling microcapsules being damaged under the action of external forces, thereby ensuring the stability of the cooling paper structure and its cooling effect.
[0016] Exemplarily, the gridded support layer in the embodiment of the utility model is a gridded carbon fiber support layer. Since the hardness of carbon fiber is relatively high, which is 3 to 10 times that of glass fiber, the protective effect of the cool microcapsules can be achieved. Not only that, carbon fiber has the characteristics of lightweight. The gridded carbon fiber support layer is provided in the cool layer to not only ensure the stability of the cool paper structure, but also ensure that the quantitative amount of the cool paper will not be too high. It should be understood that the selection of carbon fiber in the gridded carbon fiber support layer in the embodiment of the utility model can be selected according to actual conditions, and is not limited here.
[0017] In an optional manner, the mesh of the mesh support layer of the embodiment of the utility model has a mesh aperture of 40 to 100 meshes. Setting the mesh aperture within this range can make the cooling microcapsules in the cooling layer more densely filled, thereby achieving a better cooling effect.
[0018] In an alternative approach, Figure 1As shown, the facial coating structure 200 provided by the present invention may include a bottom coating layer 210, a middle coating layer 220 and a top coating layer 230, at least one of the bottom coating layer 210, the middle coating layer 220 and the top coating layer 230 being a cooling layer. The bottom coating layer 210, the middle coating layer 220 and the top coating layer 230 are sequentially distributed along the direction close to the first surface of the base paper layer, that is, the bottom coating layer 210 is formed on the first surface of the paper base 100, the middle coating layer 220 is formed on the bottom coating layer 210, and the top coating layer 230 is formed on the middle coating layer 220.
[0019] For example, when the bottom coating layer 210 is a cooling layer, it can be known from a cooling performance tester that, compared with paper without a cooling layer, the cooling coefficient of the cooling paper provided in this embodiment becomes larger, proving that the cooling layer can significantly improve the cooling degree of the paper surface.
[0020] For example, when the middle coating layer 220 is a cooling layer, it can be known from a cooling performance tester that, compared with paper without a cooling layer, the cooling paper provided in this embodiment has a larger contact cooling coefficient, and compared with a paper in which the bottom coating layer 210 is a cooling layer, the cooling paper in which the middle coating layer 220 is a cooling layer has better cooling performance, which proves that the cooling layer can significantly improve the contact cooling degree of the paper surface.
[0021] For example: when the top coating layer 230 is a cooling layer, it can be known using a cooling performance tester that, compared with paper without a cooling layer, the cooling paper provided in this embodiment has a larger contact cooling coefficient, and compared with paper in which the middle coating layer 220 is a cooling layer, the cooling paper in which the top coating layer 230 is a cooling layer has better cooling performance, proving that the cooling layer can significantly improve the contact cooling degree of the paper surface.
[0022] For example, when the bottom coating layer 210 and the top coating layer 230 are cooling layers, the cooling performance tester shows that the cooling performance of the cooling paper is better than that of the cooling paper with only one cooling layer, which proves that the cooling layer can significantly improve the contact coolness of the paper surface.
[0023] For example, when the bottom coating layer 210 and the middle coating layer 220 are cooling layers, the cooling performance tester shows that the cooling performance of the cooling paper is better than that of the cooling paper with only one cooling layer, which proves that the cooling layer can significantly improve the contact coolness of the paper surface.
[0024] For example, when the middle coating layer 220 and the surface coating layer 230 are cooling layers, a cooling performance tester shows that the cooling performance of the cooling paper is better than that of the cooling paper having only one cooling layer, which proves that the cooling layer can significantly improve the contact coolness of the paper surface.
[0025] For example: when the bottom coating layer 210, the middle coating layer 220 and the top coating layer 230 are all cooling layers, it can be known by using a cooling performance tester that, compared with cooling paper having only two cooling layers, the cooling paper provided in this embodiment has the largest contact cooling coefficient, further proving that the cooling layer can significantly improve the contact cooling degree of the paper surface.
[0026] That is to say, the cooling paper provided by the embodiment of the utility model can use any one, two or three layers of the bottom coating layer 210, the middle coating layer 220 and the top coating layer 230 on the surface of the paper base 100 as cooling layers. The specific selection can be based on actual needs and is not limited here.
[0027] In an optional manner, the waterproof layer in the embodiment of the utility model includes a nano-hydrophobic layer and a nano-dustproof layer, wherein the nano-dustproof layer and the nano-hydrophobic layer are distributed along the direction close to the second surface. It is understandable that the structure of the nano-hydrophobic layer is dense, which can prevent water molecules from penetrating the cool paper to a certain extent, thereby ensuring the stability of the cool paper structure. Furthermore, the nano-dustproof layer is provided in the waterproof layer to prevent dust from falling on the paper surface and improve the writing effect.
[0028] In practical applications, the surface coating structure can also be provided with a waterproof layer to improve the paper's resistance to water penetration, reduce the probability of ink penetrating the paper during writing, further improve the writing effect of the paper, and extend the shelf life of the paper. It should be understood that the specific position of the waterproof layer in the surface coating structure is not limited and can be adjusted according to actual conditions.
[0029] For example, Figure 1 As shown, the bottom coating structure 300 in the embodiment of the utility model further includes a sterile layer 330, which is disposed between the second surface and the waterproof layer 320 to reduce the safety issues caused by children putting the cooling paper into their mouths and improve the safety of the cooling paper.
[0030] In an optional manner, the thickness of the cooling layer in the embodiment of the utility model is 20 μm to 30 μm. Within this range, not only can the cooling paper have a certain cooling effect, but also the production cost of the cooling paper can be ensured to be within a controllable range. It is worth noting that by providing a gridded support layer in the cooling layer and cooling microcapsules in each grid in the gridded support layer, the cooling effect of the cooling paper can be improved without affecting the traditional papermaking process and coating process. In this process, there are fewer factors affecting the cooling effect, and it is easy to control the cooling effect of the cooling paper. At the same time, it is conducive to reducing production costs and controlling production costs within a controllable range.
[0031] In an optional manner, cool fibers can be added to the paper base to obtain a paper base with a cool effect. The cool fibers are one or more of modified polyethylene fibers, mint fibers, cool modified cotton fibers or polyester fibers. The mass percentage is 5-10% of the absolute dry pulp. The components contained in the paper base include at least one of chemical coniferous pulp and chemical broadleaf pulp. The specific type can be adjusted according to actual conditions and is not limited here.
[0032] In one embodiment, the paper base 100 provided by the utility model can be a paper base including cool fibers. When the paper sample is conventionally papermade, compared with the paper sample without cool fibers, the contact cool coefficient of the cool paper provided by this embodiment becomes larger, and the higher the added amount, the greater the contact cool coefficient, which proves that adding cool fibers to the paper base can significantly improve the contact coolness of the paper surface.
[0033] In one embodiment, the bottom coating structure 300 provided by the present invention is also provided with a cooling layer. Using a cooling performance tester, it can be known that compared with cooling paper without a cooling layer on the bottom coating structure, the cooling performance of the cooling paper provided in this embodiment is better.
[0034] The above is only a specific implementation of the utility model. Obviously, various modifications and combinations can be made to it without departing from the spirit and scope of the utility model. Accordingly, this specification and the drawings are only exemplary illustrations of the utility model defined by the attached claims, and are deemed to have covered any and all modifications, changes, combinations or equivalents within the scope of the utility model. Obviously, those skilled in the art can make various changes and modifications to the utility model without departing from the spirit and scope of the utility model.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be covered within the scope of protection of the utility model.
