Description

TECHNICAL FIELD [0001] The present invention relates to a manufacturing method of an environmentally friendly functional tile,

The present invention relates to a tile for interior decoration, and in particular, a natural living kaolin which is advantageous to a human body and a high living durability, as well as an atopy prevention, a deodorizing effect, a humidity control and a variety of raw materials emitting far- And a method of manufacturing the same.

Korea's cement consumption rate is the fifth largest in the world after the United States and Japan. In the domestic industry, the cement industry is the second largest carbon dioxide source after the steel industry. When carbon dioxide is blown from calcium carbonate of limestone, which is the main material of cement, it burns a large amount of greenhouse gas in the process of heating to 1,450 ° C and other processes and produces 1 ton of cement statistically until consumption Of the total amount of carbon cement in the world, there is no way to recycle waste cement up to now, which has become a major environmental disaster factor and a major global warming factor.

In addition, sick house syndrome caused by fungi and viruses became a social problem due to the influence of indoor organic matter and indoor humidity. There are many harmful substances such as volatile organic compounds, formaldehyde, carbon dioxide and so on in the new house, causing a sick house syndrome such as atopy, headache, dizziness, nausea, concentration loss and so on.

As this eco-friendly living environment and residential space have increased in interest, interior and exterior materials using chemical substances with little or no toxicity, interior and exterior materials with low emission of chemical substances contained, and interior and exterior materials using natural materials . In addition, interior and exterior materials that have been treated with antibacterial, antibacterial, or pest control, as well as interior and exterior materials with cooling and heating and humidity control functions are being developed.

According to the "Eco-friendly interior material and manufacturing method thereof" of the Korean Patent Registration No. 10-0811602 (registered on Mar. 03, 2008), the shell, the elvan stone, the phyllite stone, the red soil, the loess, the clay, Or volatile organic compounds (VOCs), which are generated in a large amount in the room, are formed by applying a coating composition of the present invention on a substrate, by coating the coating composition with a powder, paprika oil, mugwort powder, graphite, char, ), And formaldehyde, and radiates far-infrared rays, thereby enhancing energy efficiency.

However, although the environmentally friendly construction interior materials such as the above-described prior arts use organic compounds as binders such as binders or adhesives added to make suitable physical properties as an interior material, the harmful substances emitted therefrom still exist, In recent years, there has been a lack of environment-friendly answers to fatal asphyxia in the case of a fire caused by harmful substances generated by combustion of such organic compounds.

In addition, various researches have been conducted on soil finishing materials, which have been recently used for most buildings, because they have excellent infrared emissivity, deodorization rate and humidity control ability as compared with other building materials.

According to Korean Patent Application No. 10-2010-0122735 (published on November 23, 2010), 'Method and composition for soil finishing using environmentally-friendly water repellent agent ", it can be said that the largest In order to solve the fundamental problems of the soil finishing material by blocking the moisture as an element, there is provided an eco-friendly water repellent agent which is a mixture of soybean oil and vegetable oil.

However, in the conventional art, the use of the water repellent agent complicates the manufacturing process of the soil finishing material and requires a considerably long period of curing, as well as a problem of insufficient antibacterial, antibacterial or pest control by using vegetable oil having a unique flavor.

Therefore, as a paradigm for the development of new building materials, in recent years there has been a noticeable increase in the quality of life, as well as in interior materials such as floor tiles, adhesives for textiles and wallpaper, various coating agents, There is a need for an environmentally friendly functional interior material that can be applied.

On the other hand, as the urbanization progresses, most of the residential spaces are constructed of cement and concrete, and due to restriction of the ventilation and humidity control, modern diseases such as atopy are caused, and recently, deodorization, ventilation, And yellow tiles which have excellent thermal insulation effect are attracting attention again.

Generally, the loess tile is produced by mixing the raw material for improving the sintering property and various raw materials for imparting the function to the natural loess powder, pulverizing and drying it, molding it by various methods, and then firing at a temperature range of 850-1200 캜 .

The loess tile thus produced has a compressive strength of 50 kgf / cm 2 or less, which is very low in durability after application and has a disadvantage of high energy consumption due to too high firing temperature during manufacture.

More specifically, the existing technology is disclosed in Korean Patent No. 10-0377488, wherein 10 to 30 wt% of organic clay is mixed with 15 to 40 wt% of processed loess, 20 to 20 wt% 10 to 15 wt% of limestone is added to add 40 wt% of stonite and pyrophyllite to give durability, and 5 to 10 wt% of primary After sintering, the body milling raw material and a small amount of sludge are mixed, pulverized, dried, aged and formed, and then subjected to a first sintering process at a temperature of 1100-1150 ° C for 28-45 minutes.

Under the above conditions, a predetermined glaze is applied to the tile body subjected to the first firing and the second firing process is performed in the temperature range of 1030-1090 ° C for 28-45 minutes to produce the yellow tile, or the glaze and the substrate are simultaneously baked at 1170-1200 Lt; 0 > C for 40-60 minutes to produce a yellow clay tile. However, this technology has a disadvantage in that the process is complicated, and the primary and secondary firing temperatures are high at over 1000 캜, which causes a large amount of energy consumption.

In addition, when the wall construction is performed using the hard-dried yellow tile, it is necessary to use the chemical more than necessary in order to fix the yellow tile, so that the effect of the yellow loess which is beneficial to the human body is reduced, It takes a long time to work even if it is working.

Also, in the course of drying, the loess is cracked due to shrinkage, and when carrying in a hard dry condition, there is a problem that the loess tile is easily broken by the cracked portion even in a small external impact.

Hereinafter, with reference to FIG. 1, a configuration of a tile composition for environmentally functional indoor decoration according to a preferred embodiment of the present invention and a method for manufacturing the same will be described in detail. First, in step 101 of FIG. 1, a raw material for an eco-friendly functional indoor tile according to the present invention is blended. The composition of the present invention comprises 10-20 vol% kaolin, 15-20 vol% Illite, 20-25 vol% zeolite, 10-20 vol% 15-20% by volume of bentonite and 20-40% by volume of pearlite.

The kaolin has 55-65% by weight of silica (SiO ₂ ), 20-30% by weight of alumina (Al ₂ O ₃ ), 6-12% by weight of iron oxide (Fe ₂ O ₃ ) (MgO), sodium oxide (Na ₂ O), potassium oxide (K ₂ O), and calcium oxide (CaO) in addition to the main components of the feldspar. The kaolin is contained in the tile and serves to prevent atopy, deodorize, keep warm and moisturize and emit far-infrared rays.

The ilite is a fine mica-group mineral, and white streaks provide luster to tiles and enhance fire resistance.

The zeolite has a cation that is easily exchanged with Na + (or K +), is substituted with Ca 2+ or Mg 2+ in water to soften water, and has a relatively large space inside. Therefore, And functions as an adsorbent.

The elvan is mainly composed of anhydrous silicic acid and aluminum oxide which are closely mixed with quartz and feldspar, and contains a small amount of ferric oxide. As a result, the elvan is composed of 3-15,000 holes per cm 3, Since it contains inorganic salts of species, it releases the harmful metal by exchanging the heavy metals and ions in the room and emits the far-infrared rays which is favorable to the human body.

The bentonite has a high viscosity as an aggregate of fine colloidal materials and has a higher cation exchange capacity than other clay minerals. Therefore, the bentonite serves as a natural binder for the environmentally functional tile for interior decoration according to the present invention. In addition, the bentonite has adsorptivity and also functions as a deodorant and adsorbent for harmful substances in the room.

When the pearlite is observed under a microscope, the layered structure resembles the shape of the surface of the pearl shell. When the pearlite structure is heated, the pearlite is completely converted to austenite at the A1 transformation (273 ° C), and the carbon concentration in the pearlite is constant at about 0.85% , And has a small hardness and magnetic property, so that the eco-friendly functional tile according to the present invention is not broken. The pearlite also functions as a deodorizing and adsorbing agent for harmful substances in the room as a porous body.

Referring again to FIG. 1, the raw material blended in the step 101 is pulverized in a step 103, and the raw material is selected as a raw material and a fine raw material in a step 105. The raw material pulverized in the step 103 is separated into a fine raw material having a diameter of 1 mm or less and a biodegradable raw material having a diameter exceeding 1 mm. In the step 103, it is preferable to use a pulverizer or a ball milling method. In the case of using the ball milling method, it is preferable to use a normal corner of the ball, but the present invention is not limited thereto. The step 105 is the most efficient process for smoothly and smoothly treating the surface of the environmentally functional functional tile according to the present invention with the fine raw material.

First, the raw material separated into the opposite raw material is adjusted to an appropriate degree in step 107, and is stored for aging (first ripening) in the opposite raw silo in step 109. [ The ripening (first ripening) of step 109 is carried out for 30 minutes to 1 day as necessary.

Then, the aged raw material aged for a proper time is put into a tile mold in step 111 and is firstly molded. The residual raw material remaining on the upper part of the mold after the molding in step 111 is collected in step 113 in order to prevent the turbidity of the grain size and color by collecting the residual raw material in the upper part of the mold, .

Meanwhile, in step 105, the raw material separated into the fine raw material is subjected to coloring and humidity control in step 108. The coloring and humidity control in step 108 is colored with primary colors of red, yellow, and black as primary colors or secondary colors, and further simplifies the process by simultaneously controlling humidity with coloring.

In step 108, the coloring and humidity controlled fine raw materials are stored for aging (second aging) in the fine raw silo in step 110. [ The fermentation in the step 110 (second fermentation) is performed for 30 minutes to 1 day as needed.

The humidity control step of steps 107 and 108 is a process of applying moisture contained in the opposite raw material and the fine raw material, and may be sprayed with water. When the humidity control is completed, moisture contained in the opposite raw material and the fine raw material Is preferably maintained at 6-12 wt% with respect to the total weight of each raw material.

Thereafter, the milled raw material aged for a suitable time is introduced into the tile mold in step 115 and secondary molded together with the primary raw material. In the step 115, the fine raw material is charged into the primary raw material to be primary molded, and the secondary raw material is secondarily molded, whereby the surface of the environmentally-functional indoor tile according to the invention is smoothly and smoothly processed as the fine raw material by the most efficient and simple method .

The shaping step of steps 111 and 115 may be a compression molding process using a press or an extruder using an extruder so that the opposite raw material, the opposite raw material and the fine raw material have a predetermined tile shape.

Subsequently, the secondary molded product is firstly fired in the step 117. At this time, since the environmentally functional functional indoor tile according to the present invention does not undergo a separate drying step because the humidity is appropriately controlled in steps 107 and 108, the manufacturing process is further simplified and the air required for drying is shortened.

The first firing step in step 117 is a step of firing and curing a tile having a predetermined shape, and is performed in a temperature range of 700-900 ° C for 30 minutes to 4 hours.

More specifically, if the firing temperature is less than 700 ° C, softening of the frit is not sufficient, and the strength of the tile is lowered. If the firing temperature exceeds 900 ° C, However, energy efficiency is low and it is not economical. Accordingly, it is preferable that the firing temperature of the environmentally-functional indoor decoration tile according to the present invention is limited to the range of 700-900 ° C.

In the case of the first firing time of step 117, the firing is insufficient and the strength is lowered when the firing time is less than 30 minutes. If the firing time exceeds 4 hours, the firing time is within the range of 30 minutes to 4 hours It is preferable to limit it.

Next, the tile for environmentally functional indoor decoration according to the present invention is coated in step 118, and finally in step 121, it is secondarily fired.

The coating step 118 is performed in a printing manner using a pigment harmless to the human body. At this time, in the tile for environmentally-functional indoor decoration according to the present invention, the humidity is controlled by combining the coloring with the natural pigment in the fine raw material in the step 108, so that the pigment coating performed in the step 118 is combined with the color, thereby realizing a deeper, .

The second firing step in step 121 is a step of stably depositing the pigment coated in step 118 on the tile. The firing step is performed at a temperature of 700-900 캜 for 30 minutes and 4 hours.

More specifically, if the firing temperature is less than 700 ° C, softening of the frit is not sufficient, and the strength of the tile is lowered. If the firing temperature exceeds 900 ° C, However, energy efficiency is low and it is not economical. Accordingly, it is preferable that the firing temperature of the environmentally-functional indoor decoration tile according to the present invention is limited to the range of 700-900 ° C.

In the case of the secondary firing time in the step 121, the firing is insufficient and the strength is lowered when the firing time is less than 30 minutes. If the firing time is longer than 4 hours, the firing time is in the range of 30 minutes to 4 hours It is preferable to limit it.

INDUSTRIAL APPLICABILITY As described above, the tile for environmentally functional indoor decoration according to the present invention and the method for manufacturing the same are capable of preventing atopy, deodorizing effect, humidity control, and emission of far infrared rays, as well as natural kaolin and beneficial durability, By combining various raw materials, environment-friendly living environment can be provided.

In addition, according to the present invention, an eco-friendly functional indoor tile and a method of manufacturing the same can reduce the manufacturing time and perform the efficient process, thereby reducing manufacturing cost and providing a higher quality tile.

In addition, the tile for environmentally functional indoor decoration according to the present invention and the method for manufacturing the same have a natural color feeling in the manufacturing process, thereby providing a high-quality interior design having more beautiful, natural color and eco-friendly functionality.

Although the present invention has been particularly shown and described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
