Description

Method of producing loess board for building interior decoration {Method of Producing loess board for a Interior Decoration structure}

The present invention relates to a manufacturing method of the ocher board for building interior using natural ocher as the main raw material.

More specifically, a certain amount of ocher, pulp, and pine are ground in the form of sawdust, crushed wood flour, glutinous rice paste, sweet potato starch, and kelp paste. It is to provide a loess board with excellent flame retardancy, as well as a large amount of far-infrared rays and good humidity control to prevent and treat various diseases.

    As is well known, ocher is a natural substance and contains a large amount of minerals such as calcium carbonate, quartz and mica, and it absorbs far infrared rays and absorbs it into the human body, activates metabolism and blood circulation to prevent aging of the body, chronic fatigue, etc. It is effective in preventing adult diseases and contains various enzyme components. These enzymes are excellent in purifying and degrading air, removing various toxins and controlling humidity, and the most fundamental effect is to activate cell physiology and generate heat energy. It is well known that the effect of releasing harmful substances is excellent.

Due to the excellence of the loess, interior and exterior materials for building, including bricks with loess as the main raw material, have been developed in various structures and manufacturing methods. Especially, gypsum boards with sound absorption and fire protection, which are frequently used as building interior materials, are harmful to the human body. In response to the fact that it contains a lot of components and needs to be improved, boards using ocher have already been known, but the manufacturing process is not only complicated and uneconomical, but also has a weak tensile strength, which makes cracking and warping easily. There were inherent problems such as poor insulation and sound insulation.

The present invention has been made in view of this point, the present invention is based on the loess, but the pulp for maintaining the tensile strength, wood powder of pine wood with excellent insulation and sound insulation, sweet potato starch excellent in water absorption, prevents the habitat and corrosion of pests It is a manufacturing method for providing a loess board with good durability, heat insulation and soundproofing by mixing the kelp paste, glutinous rice paste with excellent adhesiveness at an appropriate ratio and pressure-molded at a constant pressure. The explanation is as follows.

In the present invention, finely powdered ocher powder, pulp, pine wood flour (sawdust), sweet potato starch, glutinous rice paste, and kelp paste are used.

In more detail, in order to manufacture the unit type ocher board of the present invention,

The first step is the filtration and extraction of the loess.

In other words, the ocher powder is diluted in water in a container and diluted to remove the substance, and only pure ocher powder of fine sediment is collected.

The next step is to have a mixing step.

The pure ocher powder obtained in step 1 is 35 to 45% by weight, pulp 5 to 10% by weight, pine wood powder (sawdust), mugwort powder, green tea powder, brown rice bran, 20 to 25% by weight mixture of rice straw powder, and glutinous rice. The mixture of paste, sweet potato starch and kelp paste in an even ratio of 1: 1: 1 is added to the mixer in a ratio of 25 to 30% by weight and mixed with each other.

In the third step, the mixed material obtained in the second step is kneaded with water. At this time, the mixed material is kneaded at a ratio of 65 to 70% by weight and water to 30 to 35% by weight.

In the fourth stage, the first drying process of the compound obtained in the third stage is performed. At this time, the drying chamber temperature is suitably about 60 to 80 degrees Celsius, and is dried for about 24 to 36 hours in a well-ventilated place. After roughening, the moisture content is between 15 and 20% by weight.

In the fifth step is a compression molding process, the compound obtained by the first drying process obtained in the fourth step in a square molding frame is pressed into a pressing press of a momentary pressure of about 200 Ton / cm and withdrawn from the mold The ocher board for building interiors is shaped like a square.

Here, the ocher board after passing through the molding frame becomes a square board having a length of 1M in width and length, and the thickness becomes a desirable height of about 1.5-2 cm.

The above specification can be adjusted according to the construction situation and conditions of the site.

Next, the sixth step is the second drying process of the ocher board obtained in the fifth step, and if it is naturally dried for about 72 hours in a well-ventilated shady place, the moisture content of the present invention is about 8 to 10% by weight. The manufacture of ocher board is completed.

In the above process, when the content of ocher powder is less than 35% by weight, the generation of bio and far infrared rays is less, and when it exceeds 45% by weight, the blending power of pulp and pine wood powder is lowered, and the glutinous rice, sweet potato starch, kelp When the mixture of the grass is less than 25% by weight, the strength of the ocher board is lowered, and when the mixture is more than 35% by weight, the ocher inherent decreases.

In addition, if the content of all the blending material is less than 65% by weight, and the weight of water exceeds 35% by weight, the dough is too thin to consume a lot of time and heat energy during the drying process, the content of the blending material exceeds 70% by weight This will make it difficult to choose a smooth and smooth dough.

On the other hand, if the moisture content in the primary drying process is less than 15% by weight, molding is unsuitable, and if it exceeds 20% by weight, solid molding cannot be expected.

And when the temperature of the drying chamber is less than 60 degrees Celsius has a disadvantage that the drying time is long, and if the temperature exceeds 80 degrees Celsius may crack in the dough due to rapid drying.

Therefore, it is possible to manufacture the best ocher boards preferred under the above contents and conditions.

The ocher board of the present invention manufactured by such a process is maintained in tensile strength by the material of pulp and pine wood flour (sawdust), and retains its original shape without deformation even if there is a lot of moisture in the rainy season by the water absorption action of sweet potato starch, The mixture of kelp, sweet potato starch and glutinous rice paste is similar to the tendency of ocher soil, so it has excellent blending power and adhesive function. Especially, it is prevented by mold, mite and harmful pests. Do it.

Such ocher board of the present invention will be used as interior materials or flooring materials of various buildings, the atmosphere of the original loess wall or floor of our country is directed, as well as the humidity control is very good by the characteristics of the loess, heat resistance and thermal insulation by heat insulation It is excellent in soundproofing and soundproofing, and it has excellent deodorizing function that removes harmful odors such as formaldehyde generated in sick house syndrome, and also has excellent effects such as bio and far-infrared ray generation, and also blocks strong alkaline harmful odors generated from cement. Will have an effect.
