DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be more clearly described with reference to the accompanying drawings.

<Example 1> A manufacturing method of the building material for the functional bio-ceramic liquid.

First, HAP (Hydroxy-Apatite), elvan, feldspar, diatomaceous earth, and water are slowly added to a stirring tank equipped with a stirrer in a uniform amount, mixed with stirring at a speed of 600 to 800 rpm for 20 to 30 minutes, and then water-soluble in acrylic Adding a liquid binder including an emulsion (ap1200) to form a mixture while stirring at a speed of 600 ~ 800rpm for 20 to 30 minutes.

The amount of each component to be mixed in the functional bio-ceramic liquid building finish material according to the present invention is 9 to 15% by weight of HAP (Hydroxy-Apatite) having a particle size of 300 to 400 mesh based on the total weight of the mixture, and 20 to 11 25 wt%, 10-15 wt% of feldspar, 20-25 wt% of diatomaceous earth, 20-25 wt% of a liquid binder containing 10-15 wt% of water and an acrylic water-soluble emulsion, wherein the elvan and feldspar are 70 ° C. 2 ~ 3 hours at ~ 80 ℃ dried by hot air to remove the water contained, and then pulverized to 300 ~ 400 mesh using a grinder was used as a raw material.

When the mixed raw materials are not stirred in the range of 600 ~ 800rpm, it is preferable to sufficiently stir at a speed of 500 ~ 600rpm because cracks or silk racks may occur during construction on the concrete surface due to insufficient mixing between input materials.

Subsequently, after the admixture is added to the mixture of the liquid binder, the mixture is sufficiently stirred at a speed of 600 to 800 rpm for 20 to 30 minutes to form a very thin liquid building finishing material, and the admixture is 2.5 weight dispersant based on the weight of the liquid binder. %, Thickener 1.5% by weight, defoamer 2.0% by weight, calcium carbonate (caco3) 5.0% by weight, regulator 1.0% by weight. Here, the dispersant used the product name HAN1288, thickener Rn2020, antifoaming agent Lymco ea2588, the modifier used the chemm-8w.

Thereafter, the building finishing material formed in the above to remove all the foreign matter or coarse particles of 300 ~ 400 mesh or more using a vibration screen, and then wrap the finish of the liquid in a container of a predetermined unit.

In addition, after mixing and admixing the admixture to the mixture of the liquid binder, if bubbles are generated in the mixture may further comprise the step of removing bubbles by using a vacuum in a closed container.

HAP (Hydroxy-Apatite), which is one of the components mixed in the functional bioceramic liquid building finishing material according to the present invention, has excellent biocompatibility and can adsorb amino acids constituting proteins and bacteria such as influenza or E. coli. As a result of investigating gas adsorption capacity, it is not only excellent in adsorption of aldehyde or odorous ammonia, which is the cause of sick house syndrome, and nitrogen oxide, an air pollutant, but also the main ingredient to neutralize, block, and stabilize cement toxicity. In the case of HAP (Hydroxy-Apatite), as can be seen through Figure 1 when less than 9% by weight is significantly reduced the ability to neutralize, block, stabilize the adsorption capacity and cement toxicity, exceeding 15% by weight If the adsorption capacity becomes stronger than necessary, it may lack workability. It is preferable to mix.

As shown in FIG. 1, when tested by the method of increasing HAP (Hydroxy-Apatite) by 3% by weight, the cement toxicity (hexavalent chromium) was 100 (ppm) when HAP (Hydroxy-Apatite) was not mixed at all. In contrast, it was confirmed by ICP and UV-spectrophotometer that the cement toxicity (hexavalent chromium) was significantly reduced to about 30 (ppm) in the mixing range of 9 wt% to 15 wt%, and the harmful odor was adsorbed and removed.

In addition, the ganbanite is mixed to block harmful odors and to release anion and far infrared rays, which are beneficial to health, and ferric oxide and calcium, magnesium, germanium, and selenium, which are necessary for the human body and living organisms based on silicic anhydride and aluminum oxide. It contains 45 kinds of minerals (MINERAL). The minerals control the development and physiological functions of the human body and living organisms, and maintain the normal vitality, and plants have the effect of promoting the development, these ganganite is less than 20% by weight or more than 25% by weight if ganvanite has Due to the inherent binding properties, the workability is lowered, and the emissivity and humidity control functions of the anion and far infrared rays are lowered, so it is preferable to mix 20 to 25% by weight based on the total weight of the mixture.

On the other hand, the ganban stone may be replaced with any one selected from germanium stone, macrorite, brown salt.

In addition, the feldspar is a mineral that is tightly coupled to fine minerals, rich in fat, and has a property of suppressing the generation of bubbles in the stirred building finish material, so the process of removing bubbles necessarily required in the prior art Can be reduced. When the feldspar is less than 10% by weight, the viscosity of the finishing material is lowered, and when it exceeds 15% by weight, the viscosity is strengthened more than necessary, so that it may lack workability, so it is mixed in 10 to 15% by weight based on the total weight of the mixture It is preferable.

In addition, the diatomaceous earth can be used properly selected from the ones produced in seawater and having fresh water, and has a pore 5,000 to 6,000 times more than the ultra-porous body of charcoal, so deodorizing ability and adsorption of harmful smell In order to maximize the addition of 20 to 25% by weight based on the total weight of the mixture, when the mixed amount of the diatomaceous earth is out of this range deodorizing ability and adsorption of harmful smell is reduced.

On the other hand, the diatomaceous earth may be replaced with any one of acidic clay, bentonite, zeolite, kaolin, feldspar.

The water is mixed at 10-15% by weight, based on the total weight of the mixture. If the water is less than 10% by weight, when the addition of admixtures for improving the physical properties, the fluidity decreases and the viscosity of the physical properties becomes too strong. When the water content exceeds 15% by weight, the fluidity is generated and flows down the concrete surface.

The liquid binder occupies the remaining portion except for the H.A.P (Hydroxy-Apatite), elvan, feldspar, diatomaceous earth, and water, and is mixed at 20 to 25% by weight based on the total weight of the mixture.

When the liquid binder is less than 20% by weight, the dry coating state or adhesive strength does not reach the standard value when the coating is applied to the concrete surface. When the liquid binder exceeds 25% by weight, the coating state dried after a certain time after being plastered on the concrete surface is visually observed. A seal crack appears when you check with.

The acrylic water-soluble emulsion contained in the liquid binder not only acts as an adhesive, but also allows the building finish to effectively penetrate the concrete surface without lifting and cracking.

In addition, the admixture for improving the physical properties added to the liquid binder is a building finish material is added to increase the hiding power and smoothness on the concrete surface, if greater than or less than 12% by weight significantly less uniform hiding power and smoothness and plastering on the concrete surface It is most preferable to mix 12% by weight since it may be difficult to smoothly apply the coating work with a tool or a roller.

The functional bioceramic liquid building finish material produced by the above method is in liquid form and sprayed onto the concrete surface through an airless spray.

The functional bioceramic liquid building finishing material of the present invention as described above was tested to evaluate various characteristics as follows, and the test result is 3.71X10²W / m² of radiant energy is emitted under the conditions of 40 ℃ as below. As can be seen from the graph, the antimicrobial and deodorizing effect was great and the generation of indoor pollutants was significantly lower than the recommended standard value.

Therefore, the particle size within the range of 200 ~ 350 mesh is used to maintain the smoothness in the field construction while maintaining the smoothness. It is desirable to improve the workability of the.

In addition, after mixing and admixing the admixture to the mixture of the liquid binder, if bubbles are generated in the mixture may further comprise the step of removing bubbles by using a vacuum in a closed container.

HAP (Hydroxy-Apatite), which is one of the components mixed in the functional bioceramic liquid building finishing material according to the present invention, has excellent biocompatibility and can adsorb amino acids constituting proteins and bacteria such as influenza or E. coli. As a result of investigating gas adsorption capacity, it is not only excellent in adsorption of aldehyde or odorous ammonia, which is the cause of sick house syndrome, and nitrogen oxide, an air pollutant, but also the main ingredient to neutralize, block, and stabilize cement toxicity. In the case of HAP (Hydroxy-Apatite), as can be seen through Figure 1 when less than 9% by weight is significantly reduced the ability to neutralize, block, stabilize the adsorption capacity and cement toxicity, exceeding 15% by weight If the adsorption capacity becomes stronger than necessary, it may lack workability.
