Description

The composition of Hwang brick and Hwangtho Tile Activated With Hwangtho, Illite and Titanium Oxide and its Manufacturing Methods

The present invention is a building ocher bricks and ocher tiles as a high far-infrared emissivity and deodorization rate to clean the indoor air, more specifically ocher and illite, titanium dioxide , Odorite, titanium dioxide which can deodorize, adsorb and maintain temperature and humidity by activation It relates to a composition of activated ocher bricks and ocher tiles and a method of manufacturing the same.

Generally, ocher bricks and ocher tiles are known to have higher temperature and humidity control functions and higher health benefits than cement bricks manufactured mainly from cement.

Existing cement bricks have low temperature, humidity, far-infrared emissivity, and deodorization adsorption performance, and red bricks have poor porosity and absorption due to high temperature firing at 1200 ° C. or more, resulting in low performance and high cost.

In addition, conventionally used ocher bricks and ocher tiles are uneconomical in that an excessive fuel cost is consumed due to high temperature firing, and there is a problem in that strength and durability fall due to whitening after construction.

And relates to a conventional ocher brick, Patent Registration No. 0239853, Patent Publication No. 2000-0012566, Patent Publication No. 2000-0033318 by using a natural loess put straw, herbs, organic binders, etc., compressive strength 40 Since it is about 50 kgf / cm 3, there is no water resistance, and in Korean Patent Laid-Open Publication Nos. 1999-0064871 and 2000-0012566, cement, lime, and the like are added to compensate for the strength. Humidity control is poor and the content of ocher is limited. In addition, the method of manufacturing brick using ocher soil by mixing ocher, cement waterproofing liquid, red iron oxide, etc. is disclosed in Korean Patent Publication Nos. 89-368, 85-5395, and 90-12862. The method emits a small amount of far-infrared emissivity and has a weak deodorization and a weak temperature and humidity control function.

The activated ocher bricks and ocher tiles of the present invention improve these problems, and have high compressive strength, good far-infrared emissivity and deodorization adsorption, so that the room is warm and does not occupy moisture and removes odors with excellent adsorption power, and has excellent antibacterial properties such as molds. , Illite and Titanium Dioxide to Suppress Breeding To provide a composition of the activated ocher bricks and ocher tiles and a method of manufacturing the same.

The present invention, in order to achieve the above object, by crushing the natural ocher and illite (Illite) to correct the moisture adjustment to 10 to 30%, using a wet pan mill (Wet pan mill) After kneading by kneading, press molding with a vacuum drill or a press is carried out at 10 to 100 ° C. for 24 hours to dry naturally.

In order to activate the dried ocher brick and ocher tile, it is characterized by performing high temperature drying at 300 to 980 ° C.

Natural ocher and illite (Illite) can suppress the occurrence of cracks after activating the size of the particles up to 2.0mm or less, the surface may become rough when the particles are more than 2.0mm.

Kneading with wet pan mills requires a uniform moisture content to eliminate the double layer during molding and prevent cracking during drying and activation at high temperature drying.

Ocher and Illite, Titanium Dioxide Activated ocher bricks and ocher tiles mixed with the composition can be applied to the interior and exterior walls of a conventional building, can be added tourmalin for the function of the release of negative ions.

It is very important that the heating rate is slowly heated to about 1.5 ~ 5.0 ℃ / min when drying at high temperature with activation temperature of 300 ~ 980 ℃, and the optimum holding time after raising the temperature is 1 ~ 5 hours.
