Description

A white board with antibacterial function using yellow earth and method

The present invention relates to an antimicrobial functional white paper using a loess used for packaging and to a method for producing the same, and more particularly, using the loess having a particle size of 50 microns or less refined, The present invention relates to an antibacterial functional white cardboard using ocher for forming anti-microbial functionality by forming a film on a specific layer among the various layers constituting the white cardboard as a method of treating together.

In general, the white paper produced by recycling recycled paper is used as a packaging material by providing functionality through various functional granting steps to protect agricultural products and food interior materials and make the interior materials stand out.

As an example, the surface layer (3) and the subsurface layer (4) through dissociation, storage, selection and concentration, storage, stuff box, injection, and dehydration of raw materials into different kinds of waste paper as shown in FIG. The material of each layer, such as the core layer 5 and the back layer 6, is formed. Here, the water-resistant agent is added to the composition surface layer 3 stock, but not to the stock of the remaining layers. Subsequently, the sheets of each layer dispersed in about 99% of water are injection-dehydrated onto a wire to form a sheet. Next, the formed papers are sequentially stacked on each other. Subsequently, the paper passed through the stacking step as described above is forcibly dehydrated in a press. After the forced dehydration step, the paper is pre-dryed by applying 60-180 ° C heat. Then, in order to enhance the water resistance and strength, a solution containing modified starch and polyvinyl alcohol was applied to the surface layer 3 in a size press and heated at 100 ° C. or higher to give a surface of 0.5-3.0 g / m 2. The film layer 2 is formed. The rewetted paper is then dried again to balance the proper moisture. Next, the rolls in the calendar adjust the thickness of the paper and flatten the surface. Subsequently, the surface film layer 2 is coated with a solution composed of clay, calcium carbonate, and latex three times to 5-30 g / m 2 in order to be smooth and beautiful. Then, in order to solve the problem of the lack of strength, such as distortion or deformation caused by the front and back difference occurs, the back layer 6 is coated with a solution containing starch, polyvinyl alcohol, and wax to the back film of 0.5-3.0g / ㎡ Form layer 7.

As described above, the water-resistant agent may be internalized in the surface layer material composition process, but the water-resistant agent may be coated in a size press to impart water resistance.

In this way, a white cardboard as shown in FIG. 1 is manufactured, and the white cardboard produced in the above-described continuous process is rolled up to the rotating body of the drum by pope reel.

Here, the process of forming the material of the surface layer 3 is different from the process of forming the material of the subsurface layer 4, the deep surface layer 5, and the rear layer 6, so that the raw material is not selected and concentrated through the storage tank after dissociation of the raw material. It is only to select and confess, but because the raw materials used in the material preparation process of the subsurface layer (4), the deep surface layer (5), and the back layer (6) is a recycled paper to remove the dirt and foreign substances contained in the raw material. This is because not only the selection process but also the concentration process to make a low concentration of the raw material to a high concentration, but the raw material used in the material composition process of the surface layer (3) is enough to go through the selection and beating process using wood pulp.

However, the white paper produced by such a process has a beautiful appearance and sufficient strength as a packaging material through the printing process, but it is insufficient to maintain the freshness and life of agricultural products and foods for a long time, thus extending the freshness and life of these agricultural products and foods. In order to have a double packaging had a problem.

The present invention is to solve the above problems and to provide the antimicrobial functionality to the white paper by the method of embedding or coating each layer, such as the material, surface, and / or the back of the loess that emits far infrared rays with antimicrobial functionality for customer satisfaction Its purpose is to produce antimicrobial functional cardboards using ocher, which can extend the freshness of agricultural products and food packaging materials and the life of packaging materials.
