The present invention relates to an architectural panel using shells and red clay and a method of manufacturing the same. More specifically, an architectural panel using shells and red clay that is eco-friendly and provides the functionality of emitting far-infrared rays using discarded shells and red clay, and the same. The purpose is to provide a manufacturing method.

Oyster shells or clam shells are classified as industrial waste, and hundreds of thousands of tons are generated annually, mainly on the southern coast.

Some of these shells are used as seedlings for oyster farming, and some are consumed as a substitute for limestone in steel mills, etc., as shown in Korean Patent Publication (B1) 10-2220541 (2021.02.25.) , a large amount of shells are being left unloaded.

Recently, building materials using shells have been developed, and a representative example is the method of manufacturing building materials using red clay in Republic of Korea Patent Publication (B1) 10-0809446 (2008.03.06.), but this has a low consumption rate of shells. It is pressure molded at high temperature.

Another representative example is Korea Patent Publication (B1) 10-0811602 (2008.03.11) providing an eco-friendly interior material and its manufacturing method, which includes shell, elvan, phyllite, red clay, red clay, white clay, A colored layer containing one selected from the group consisting of green tea leaves, coffee powder, spinach powder, paprika oil, mugwort powder, graphite, charcoal, and mixtures thereof, a rare earth anion agent, elvan, zeolite, A coating layer containing one selected from the group consisting of phytoncide, titanium dioxide, hinokitiol, sulfisomidine, polyphenol, terpene, and mixtures thereof, and a group consisting of silver nano and fragrance capsules on the coating layer, and mixtures thereof It is designed to include a nano coating layer containing one type selected from.

Another example is the Republic of Korea Patent Publication (B1) 10-1815018 (2018.01.08.), which provides an eco-friendly building material composition using oyster shells, an eco-friendly building material, and a manufacturing method thereof, which contains photosynthetic microorganisms and stores them. After putting oyster shells into a microbial reaction device to remove odor and decompose proteins generated from oyster shells, 35 to 60 parts by weight of oyster shell powder obtained through washing, drying, and grinding steps, ash soil, stone dust, kaolin, red clay, and natural 40 to 65 parts by weight of mixed aggregate containing at least one of pozzolan, illite, perlite and elvanite, 30 to 40 parts by weight of CaO, 20 to 35 parts by weight of SiO2, 10 to 20 parts by weight of Al2O3, and 1 to 5 parts by weight of SO3 10 to 35 parts by weight of eco-friendly cement consisting of 1 to 5 parts by weight of MgO and 1 to 6 parts by weight of Fe2O3, 50 to 60 parts by weight of Ethylene-Vinyl Acetate Emulsion, and Acrylate polymer emulsion. ) A building material composition is provided, including 20 to 30 parts by weight, 5 to 10 parts by weight of synthetic rubber latex, and 5 to 30 parts by weight of a polymer liquid curing agent diluted with water 1:4. The goal is to manufacture eco-friendly building materials.

Although much development has been done in building materials using red clay and shells as described above, there are problems such as easy brittleness and difficulties in construction, and in order to prevent cracking or breaking by improving cohesiveness even when drying, it is necessary to manufacture It has the disadvantage of rapidly increasing costs, and in particular, the disadvantage of having to go through a complex manufacturing process to add flame retardant and insulation functions is still not resolved.

It consists of applying a mixture (4) made by mixing shell and red clay to the upper side and combining it to a certain thickness.

The base panel 2 is preferably made of wood, and wood boards, plywood, etc. may be used, and in some cases, metal or non-metal boards may be used.

The mixture (4) can be divided into a lower mixture (4-1) and an upper mixture (4-2) based on the mesh (5) embedded inside.

Glue is used as the adhesive (3), and any one of animal glue, bladder glue, seaweed glue, and starch glue can be used.

The shells used in the mixture (4) are pulverized to 5 mm or less after removing odors and undergoing a washing and drying process, and the red clay is used after sieving to separate large particles such as pebbles.

The appropriate mixing ratio is 30-40% shell powder and 60-70% red clay, and add it to the stirrer with water to ensure sufficient stirring.

The mixture (4) may include short fibers (6). It is preferable to use single fibers (6) with a length of less than 10 mm.

The mesh (5) is composed of a mesh (width x height) of 10 to 20 mm in size so that the mixture (4) can easily pass through. The mesh (5) and short fibers (6) are made of natural fibers and can be disposed of when discarded. Make sure there is no concern about environmental pollution.

Additionally, paper (7) can be further attached to the top of the upper mixture (4-2). Paper (7) can be applied to various things.

The paper 7 can be joined without adhesive, but since the paper 7 may be separated in a dry state, it is preferable to apply the adhesive before joining. A preferred example of the paper 7 is combining Korean paper to ensure breathability of the mixture 4 and to allow the ocher color of the mixture to subtly permeate.

Figure 2 shows a cross-sectional view showing a second preferred embodiment of a building panel using shell and red clay provided by the present invention.

This is to increase the bonding strength between the base panel (2) and the mixture (4) by fixing the net (5) to the base panel (2) in constructing the building panel (1) using shell and red clay as in the first embodiment. It was made possible.

For this purpose, in the second embodiment of the present invention The net (5) can be fixedly installed at a certain height on the upper side of the base panel (2) using the first and second fixing pins (8) and (9).

A preferred method of fixing the net (5) using the first and second fixing pins (8) and (9) is to place them on the lower side of the net (5). After fixing the first fixing pin (8) to the base panel (2), place the net (5) on the upper side, and place the net (5) on the lower side of the net (5). From the upper side of the net (5) at a right angle to the first fixing pin (8) The second fixing pin (9) is coupled to the base panel (2) so that the net (5) can be fixed between the upper and lower first and second fixing pins (8) and (9).

The first and second fixing pins (8) and (9) are designed so that they can be easily driven into the base panel (2) made of wood or plywood by forming cutting edges at both ends, and can be taka pins used for woodworking, etc. there is.

In addition, the first and second fixing pins (8) and (9) are coupled to the base panel (2) at regular intervals, and are preferably installed continuously at intervals of 50 to 100 mm to have the function of fixing the net (5). It provides an anchor-like role that holds the lower mixture (4-1) and the upper mixture (4-2).
