The technical features of the present invention will be described in detail below with specific embodiments and accompanying drawings, so that those with ordinary knowledge in the technical field can easily understand the purpose, technical features, and advantages of the present invention.

In order to facilitate your examiner to understand the technical features, content and advantages of the present invention and the achievable effects, the present invention is described in detail in conjunction with the drawings and in the form of expressions of the embodiments, and the drawings used therein, which The main purpose is only for illustration and auxiliary description, not necessarily the true proportion and precise configuration after the implementation of the present invention, so the proportion and configuration relationship of the attached drawings should not be interpreted and limited to the scope of the present invention in practical implementation. He Xianming.

Hereinafter, embodiments of the synthetic paper and the manufacturing method thereof according to the present invention will be described with reference to related drawings. For ease of understanding, the same elements in the following embodiments will be described with the same symbols.

Please refer to FIG. 1 and FIG. 2, which are the schematic structural diagram of the synthetic paper of the present invention and the first flow chart of manufacturing the synthetic paper of the present invention.

As shown in the figure, the synthetic paper 1 of the present invention includes a paper body 10 and at least one coffee grounds layer 20. Among them, the paper body 10 is a sheet-like structure made of materials including pulp and the like using a process well known to those skilled in the art. The coffee grounds layer 20 is disposed on at least one side of the paper body 10 through a coating and printing process using a coating solution. In this way, waste coffee grounds can be effectively recovered and reused, and the amount of pulp used can be reduced.

For example, under the condition of the same or close pounds, the synthetic paper 1 of the present invention can effectively reduce the amount of pulp compared to paper made by conventional techniques, and is formed by coffee grounds. Coffee grounds layer 20 instead.

Wherein, the coating solution is mainly formed by mixing a coffee pulp, a dispersant, an adhesive and a color material, and the coffee pulp contains a coffee ground recovered after use.

It is worth mentioning that the manufacture of synthetic paper includes the following steps: (S11) provide a paper body; (S12) prepare a coating solution; the coating solution consists of a coffee pulp, a dispersant, and an adhesive Mixed with a color material, and the coffee slurry contains a coffee grounds recovered after use; (S13) using a coating printing process to set the coating solution on at least one side of the paper body; (S14) roasting at 65 ~ 75 ℃ 15 to 30 seconds to form the coffee grounds layer.

Incidentally, when the coating printing process is performed, the coating printing equipment commonly used by those with ordinary knowledge in the technical field can be selected, or the coating printing equipment after a predetermined configuration can also be used. In addition, the coating printing process and the subsequent baking process can also be integrated on the coating printing equipment, such as baking directly after coating printing.

Please refer to FIG. 3, which is a second flow chart of manufacturing synthetic paper of the present invention. Fig. 3 is mainly for explaining the preparation of the coating solution.

When preparing the coating solution, the recovered coffee grounds and the dispersing agent are mixed and stirred to form a coffee slurry, and then the coffee slurry, dispersing agent, adhesive and colorant are mixed and stirred to form a coating solution.

That is to say, when preparing the coating solution, the following steps are included: (S21) Mixing and stirring the coffee grounds and the dispersing agent into a coffee slurry; (S22) Providing dispersing agents, adhesives and colorants; (S23) Dispersing the coffee slurry, The dispersant, adhesive and color are mixed and stirred into a coating solution.

It should be noted that coffee pulp accounts for 26 to 30% by weight of the coating solution, dispersant accounts for 2 to 5% by weight of the coating solution, and adhesive accounts for 55 to 62% by weight of the coating solution. The material accounts for 10 to 14% by weight of the coating solution.

Preferably, the coffee pulp accounts for 27 to 29% of the coating solution weight, the dispersant accounts for 2 to 4% of the coating solution weight, the adhesive accounts for 59 to 62% of the coating solution weight, and the colorant accounts for 9 to 11% by weight of the coating solution.

As far as the coffee pulp is concerned, coffee grounds account for 61-64% by weight of the coffee pulp, and dispersants account for 36-39% by weight of the coffee pulp.

Among them, the coffee grounds in the coffee slurry can be recovered to a predetermined mesh by grinding, wherein the predetermined mesh can be adjusted according to actual use, and will not be described again; then it is mixed with the dispersant. The dispersant added in the coffee slurry and the dispersant added in the coating solution may be well known to those skilled in the art.

In addition, the adhesive can be, for example, a durable resin, and the color material can be selected according to the actual application. For example, a white color paper can be used for the paper body with a white background.

With the coating solution made by the above configuration, after the coffee grounds layer is formed on the paper body, it does not cause the problem that the whole synthetic paper is too brittle to be bent and cannot be used, or the coffee grounds layer cannot It sticks to the paper body steadily and easily detaches.

Please refer to FIG. 4, which is a schematic structural view of another embodiment of the synthetic paper of the present invention. In this embodiment, it is mainly to illustrate that the coffee grounds layer 20 can be disposed on both sides of the paper body 10 through a coating and printing process using a coating solution, and the rest are the same as in the previous embodiment, which will not be repeated here. .

In the following, the advantages of the present invention will be further described with comparative examples.

Comparative Example 1, which is applied to notebook paper (size: 21×15 cm): 132 gsm of Doolin paper is approximately 4.16 g per sheet; 132 gsm of synthetic paper of the present invention is approximately 4.16 g per sheet, of which the paper body is approximately 3.16 g, and the coffee grounds layer is about 1 g. It can be seen from the above that each sheet of paper can save about 1 g of pulp, and for a 70-sheet notebook, it can save 70 g of pulp. Among them, the carbon emission of one piece of 132 gsm of Doolin paper is 0.00475kg, and the carbon emission of one piece of 132 gsm of synthetic paper of the invention is 0.00388kg, so each notebook can save about 0.0609kg (0.00499-0.00388= 0.00087, 0.00087×70) carbon emissions.

Comparative Example 2, which is a food box applied to predetermined foods: 295 gsm food cards each about 17.25 g; 280 gsm synthetic paper of the present invention each about 17.25 g, wherein the paper body is about 16 g, and the coffee grounds layer About 1.25 g.

Comparative Example 3, which is applied to tote bags: 140 gsm kraft paper about 66 g per sheet; 120 gsm synthetic paper of the present invention about 66 g per sheet, wherein the paper body is about 56 g and the coffee grounds layer is about 8 g .

As can be seen from the above comparative examples, under the condition of the same or close pounds, the synthetic paper of the present invention can indeed effectively reduce the amount of pulp compared to the paper made by the conventional technology, while using coffee grounds The coffee grounds layer formed as an alternative.

The above is only exemplary, and not restrictive. Any equivalent modifications or changes made without departing from the spirit and scope of the present invention shall be included in the scope of the attached patent application.
