Description

Functional panel using volcanic rock and its manufacturing method {Panel using volcanic rocks and method for preparing the same}

The present invention relates to a functional panel using volcanic rock and a method of manufacturing the same. More specifically, the use of volcanic rock (frost, matsutake) is excellent thermal insulation, deodorization, moisturizing effect, environmentally friendly and no fire risk In addition, the present invention relates to a building functional panel using volcanic rock material in which a large amount of far-infrared rays are emitted, and a manufacturing method thereof.

In general, partition panels, which are prefabricated, are frequently used to quickly and easily partition the interior of an office, and various partition panels used in this way must be nonflammable and have noise blocking to reduce the risk of fire. It can be said that it is preferable.

However, conventional partition panels are manufactured and installed mainly in a state in which a predetermined space portion is formed between the plywood and the plywood, so that the effect of noise blocking is poor, and paper corrugated paper zigzag formed in the space portion between the plywood and the plywood. There were panels for partitions that filled the walls with noise blocking functions, but both the plywood on the surface and the corrugated cardboard inside were well-burned, causing a high risk of fire.

As such, the panel for building materials must be able to withstand heavy loads, be able to withstand high heat, have durability and fire resistance, and need to be light in weight because it must be able to lightly construct the entire load of the building. .

On the other hand, when urethane foam is used as a main material, since the urethane foam is resin-based, it is highly flammable and generates a deadly toxic gas at the time of combustion.

Looking at the prior art to solve these problems (durability and fire resistance), the Utility Model No. 0254874 proposes a panel for building materials in which a vegetable or animal foaming agent is introduced during a mixing process of gypsum, cement, or a mixture of modeling powder and water. In Korean Patent Laid-Open Publication No. 99-074050, a method of manufacturing a non-flammable panel for partitions, in which light weight is not easily burned by coating gypsum on a small granular styropole ball and then molding it into a panel form. Is starting.

In addition, Korean Utility Model Registration No. 0241744 discloses a non-combustible decorative panel including ocher, and Patent No. 0138273 describes a foamed polystyrene foam layer in which 75% of insulating foam, 20% of cement, and 5% of fiber yarn are mixed in a central part. The building wall was formed by placing a wire mesh on both sides of the foamed polystyrene foam layer and then placing a lightweight fiber concrete layer mixed with 45% vermiculite, 50% cement and 5% fiber yarn on both surfaces of the foamed polystyrene foam layer. It relates to a method for producing a panel.

However, the above-mentioned techniques are not appropriate given the reality that the human body prefers harmful natural materials. Therefore, there is an urgent need to develop materials that are friendly to the human body and help the health of the interior materials.

In order to solve this problem, it is used in the form of wet, tile or marble by using minerals such as ganban stone that emits far infrared rays, but these are used due to the high price of products and construction cost due to the processability and difficulty of production. Its use was not wide and there was a disadvantage that the variety of products was less.

Accordingly, the present invention has found that a panel manufactured using volcanic rocks scattered on Jeju Island in Korea can solve the above problems, and the present invention has been completed based on this.

Accordingly, it is an object of the present invention to provide a method for manufacturing a building panel in which thermal insulation, deodorization, and moisturizing effect are excellent using volcanic rock material, and are environmentally friendly, and far-infrared rays are emitted in large quantities, without any fire risk.

Another object of the present invention is to provide a panel manufactured by the above method.

Method for producing a panel using the volcanic rock of the present invention for achieving the above object is, in the manufacturing method of the building panel, 950-1,250mm by weaving a 0.1-5mm wire in 2-50mm horizontally and 2-50mm vertically And finishing with a length of 1,850 to 2,450 mm to space the lower wire mesh and the upper wire mesh at predetermined intervals, and connecting the lower wire mesh and the upper wire mesh with a wire to provide a double overlapped wire mesh. And a mixture of a volcanic rock material having a particle size of 250 to 300 mesh and a nonflammable and natural adhesive evenly mixed at a weight ratio of 70:30 to 80:20 to the wire mesh so that the upper wire mesh is inserted into the middle of the panel. The wire mesh provides a sheet positioned at the bottom of the panel; And drying the sheet.

The building panel of the present invention for achieving the above another object is manufactured by the above method and used as a building finishing material, partition, or flooring of a functional sauna, toilet or building.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

The volcanic rock material scattered in Jeju Island, Korea, which is used as the main component of the panel of the present invention, is a natural volcanic ash produced by lava fire naturally by high temperature and high pressure gas energy of 1,600 ° C or higher.

The volcanic rock is smaller than volcanic coal and is a volcanic emission of particles larger than volcanic sand. For reference, the far-infrared emissivity (5-20 μm) of the volcanic rock material using the FT-IR spectrometer is about 92.5% at 40 ° C., and the emission energy is about 3.72 × 10 ² W / m 2 · μm and 40 ° C.

According to the present invention, the volcanic rock is collected and various kinds of dirt and soil are removed and put into a grinder to be used by grinding the average particle size to 250 mesh or more, preferably 250 to 300 mesh. If the particle size is less than 250 mesh, the adhesive force is reduced because the particles are large, and may be larger than 300 mesh, but about 300 mesh is preferable in terms of economical efficiency.

In the present invention, the volcanic rock material powder is mixed evenly with an adhesive, preferably a non-combustible adhesive or a natural adhesive, in a weight ratio of 70:30 to 80:20 to produce a sheet having a thickness of 1 to 20 mm.

As the non-flammable and natural adhesives preferred in the present invention, a mixed adhesive of rosin and starch is used, and if the amount thereof is less than 20% by weight, the adhesive strength is lowered, and if it exceeds 30% by weight, economical tendency is inferior.

The mixing ratio of the rosin and starch is preferably about 3: 1 by weight, and the mixture is heated to 40 to 60 ° C. for at least about 2 hours, preferably 2 to 3 hours, to be used in liquid form.

On the other hand, the panel according to the present invention is manufactured in a height-adjustable rectangular frame (form-form) bonder, the mixture of the volcanic rock powder and the adhesive as shown in FIG. The thickness can be adjusted to the desired conditions.

The wire mesh is manufactured separately according to the use and the standard.For the finishing material panel, 0.1 ~ 5mm steel wire is woven into 2-50mm horizontally and 2-50mm vertically and finished in 950-1,250mm horizontally and 1,850-2,450mm vertically. The lower wire mesh 1 and the upper wire mesh 2 are spaced apart at predetermined intervals and used to overlap each other.

The reason why the two sheets overlap is that the upper wire mesh (2) is inserted into the middle part of the panel (5), the lower wire mesh (1) is located under the panel (5) to firmly support the panel (5) to always maintain durability, The lower wire mesh (1) and the upper wire mesh (2) is connected by a connecting wire (4) to enhance the workability to facilitate use.

In the present invention, the thickness of the panel is determined by filling the volcanic rock material 3 to be twice the thickness of the two wire meshes seated on the bonding machine. The panels thus prepared are dried in a drying chamber, and the dried panels are cut and processed according to the use and specifications.

In addition, the partition panel can be assembled using a specially made prefabricated angle to form a space in the middle portion for insulation and insulation.

As such, the panel manufactured according to the present invention has various uses, such as building finishing materials, partitions or functional saunas, toilets, or floors of buildings, depending on the manufacturing method. In addition, volcanic rock is an environmentally friendly material and has a beneficial effect on fire prevention and health.
