Description

Building panel with yellow soil as a main material

The present invention relates to a building panel composed mainly of ocher. More specifically, the mixture of fine ocher powder, sawdust, rice husk, etc. is mixed in a predetermined ratio, and then formed into a plate shape by adding an adhesive material of seaweed components, and dried on the front and rear surfaces thereof. The present invention relates to a protective fabric and a damp paper.

As is well known, ocher has excellent far-infrared radiation effect and antibacterial resistance. When used as interior materials of buildings, it is cool in summer, warm in winter, warm in winter by promoting metabolism, fatigue recovery, insulation, insulation and sound insulation. There is an excellent effect that other building interior materials do not have, such as to prevent the occurrence of mold.

In traditional buildings, ocher was widely used for walls and roofs in traditional buildings, but ocher has a weak bonding strength. Therefore, it is usually made of dough reinforced with vegetable fibers such as straw. As it was necessary to overcoat with plaster to make up for the disadvantages of low weathering, there were many limitations in using it as interior materials of buildings.

In order to solve the above problems, as a building material mainly based on loess, it is mixed with waste paper powder, powdered gypsum, water, foaming agent and coating binder, and attaches protective paper to the surface and the backing. It was known in Korean Patent Registration No. 162618, and the ocher board, which was formed by using ocher, hemp and back cement, and made paper on the front and woven fabric on the back, was known as Utility Model Registration 20-0189540. However, conventional interior boards based on loess are inevitably formed to be thick in order to compensate for the low bonding strength, which is a problem of loess. In order to reduce the weight and prevent cracking, There is a problem in that it is difficult to make use of the inherent advantages of ocher, such as the need for chemical additives.

The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a thinner and lighter panel with ocher as the main material which is excellent in heat insulation, heat insulation, and sound insulation.

Another object of the present invention is to minimize the cracks caused by shrinkage when the ocher-based panel is dried.

Another object of the present invention is to use seaweed extract harmless to the human body to increase the bonding strength of the ocher-based panel.

Another object of the present invention is to prevent moisture from penetrating from the outside to a panel made of ocher after construction, to have a longer service life.

※ Explanation of code for main part of drawing

3. Fabric

Hereinafter, the configuration of the present invention will be described in detail with reference to the drawings.

Figure 1 relates to a process for manufacturing a panel based on the loess of the present invention, the present invention is to remove the foreign matter by removing the high-purity ocher, and then pulverized and finely divided to remove the foreign matter or fine powder using a sawdust and chaff screen Select only those with a certain particle size.

The selected raw materials are uniformly mixed in the ratio of 70 to 80% of ocher, 18 to 25% of sawdust, and 2 to 3% of chaff.

Seaweed extract to increase cohesiveness of ocher, sawdust and rice husk boils seaweeds such as wood starfish belonging to red algae to make extract and remove undissolved debris.

Add 3-10% of seaweed extract and 30-70% of water to the ocher mixture by weight and stir.

At this time, if the moisture content is increased, stirring and molding is easy, but it causes cracks during drying, and if the moisture is insufficient, the stirring and molding is difficult. Therefore, the addition ratio of water should be adjusted according to the stirring and molding means.

Before putting the stirred ocher dough into the mold, it is preferable to lay the release paper on the bottom and side of the mold.

This is to facilitate the separation of the dried ocher plate and the mold.

The ocher mixture injected into the mold is compression molded and if the bubbles are not sufficiently removed in the ocher mixture, it is preferable to remove the bubbles by applying a constant pressure since it causes cracks during drying.

The molding method may be a molding method using a plate-like mold or a continuous molding method using a roller.

The molded ocher plate is dried by natural drying method for 2 to 3 days, then the ocher plate and the mold are separated, and the release paper attached to the ocher plate is removed, followed by hot air drying.

When hot air drying, both sides of the panel should be dried at the same time to prevent deformation due to drying, and drying is appropriate for 1 to 2 hours at a temperature of 150 ~ 200 ℃ of hot air.

If the temperature of the hot air is too high and drying proceeds rapidly, it may cause cracking or deformation of the panel.

Sawdust and chaff mixed in the panel minimize the cracks by absorbing moisture and shrinkage when shrinking due to drying of the ocher.Sawdust and chaff, which have a lighter specific gravity than ocher, work with seaweed extract to increase cohesiveness of ocher. At the same time it can reduce the weight and form a fine pore to act to enhance the insulation, insulation and sound absorption.

After hot air drying, the panel is cooled sufficiently at room temperature, and then the surface is finished by grinding, etc., and then the protective paper and fabric are attached to the surface.

Attaching a moisture-proof paper to prevent the penetration of moisture on the back and side of the panel, and attaching a textile paper on the front to dissipate the active ingredient peculiar to ocher, the building panel with the loess of the present invention is completed.

The molding standard of ocher plate is 91Cm wide, 182Cm long and 1.2Cm thick, so it can be molded according to the standard of interior materials, but it is not limited to the above standard for considering the breaking strength of ocher plate and for convenience of handling.

As described above, the present invention is more firmly manufactured using a natural adhesive material that is thinner, lighter and harmless to the human body, which is mainly made of ocher with a far-infrared radiation effect and antibacterial effect, and has a heat insulating, thermal insulation, and moisture-proof construction panel. It has the effect of providing a way.
