Description

[0001] The present invention relates to a colored building material using a catalyst impregnation method and a method for manufacturing the same,

The present invention relates to a colored building material using a catalyst impregnation method capable of preventing the discoloration, discoloration and contamination by wastewater by preparing a colored building material through a catalyst impregnation method and a method for producing the same.

Recently, many techniques for using colored stones as building materials and interior and exterior materials of buildings have been introduced. As the stone market is growing and the national income is increasing, buildings are becoming more sophisticated and consumers' tastes become more diverse. The price of colored stones is increasing due to the increase in demand due to the low production of scarce materials. At the end of the 1990s, dyeing was attempted to apply the desired color dyes to the stones after coloring by applying the demand of the colored stones at home and abroad. However, it failed to penetrate into the stone pores of the nano unit, causing water to fall off, discoloration and discoloration, and environmental pollution caused by waste water.

In addition, the price of stone varies according to the difference of kinds, characteristics and colors. However, there is a problem that the difference in color is insignificant in comparison with the color difference in the case of the non-specialist.

Currently, a large part of high-priced color building materials is dependent on imports, and domestic stone industry is recognized as a specification industry and is in a recession period, so it is essential to develop domestic production techniques for colored stones.

Uniform reference designators throughout the specification refer to like elements.

In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The terms used below are defined in consideration of the functions of the embodiments of the present invention, which may vary depending on the intention of the user, the operator, or the custom. Therefore, the definition should be based on the contents throughout this specification.

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

1 is a flowchart illustrating a method of manufacturing a colored building material using a catalyst impregnation method according to the present invention. As shown in FIG. 1, a step (S100) of producing a pore-formed support; (S200) impregnating the support with the pores formed thereon after the catalyst is manufactured; And a step (S300) of heat-treating the impregnated support to develop a hue, thereby providing a method of manufacturing a colored building material using a catalyst impregnation method.

In the step (S100) of producing the pores-formed support, mixing the aluminum oxide powder, the carbon black and the binder to prepare a mixture; Drying and pulverizing the mixture to prepare a support powder; Molding the support using the support powder; And forming a pore in the formed support. The present invention also provides a method for manufacturing a colored material using the catalyst impregnation method.

FIG. 2 is a flow chart showing a support manufacturing step (S100) according to the present invention, and the support manufacturing method according to the present invention is a method for manufacturing a support according to the present invention, comprising the steps of: mixing aluminum oxide, carbon black and binder; drying and pulverizing; forming a support; And a heat treatment step for heat treatment. First, as shown in Fig. 2, the method for producing a colored material of the present invention produces a pore-formed support.

Next, the step (S110) of preparing the mixture by mixing aluminum oxide, carbon black and a binder is carried out by mixing 15 to 35 parts by weight of the carbon black for forming pores with 100 parts by weight of the aluminum oxide powder, And 0.1 to 2 parts by weight of the binder are mixed to prepare a mixture. When the amount of the carbon black is less than 15 parts by weight, the number of pores is insufficient. When the amount of the carbon black is more than 35 parts by weight, the number of the pores is excessive and the support may be easily broken. Since the aluminum oxide powder is fine, it is difficult to form a support, so that a binder which improves the formability is prepared by mixing. When the amount of the binder is less than 0.1 part by weight, the mixture does not aggregate and the mixing is not good. When the amount of the binder is more than 2 parts by weight, the mixture may be cured. Types of binders can be divided into an inorganic binder and an organic binder. As the binder, a polyvinyl butyral resin which is an organic binder was used. The polyvinyl butyral resin has strong adhesive force, but its melting point is 90 ~ 120 ℃, which is weak against heat and can be easily removed by heat treatment.

Thereafter, the mixture is mixed with acetone, wet-ball-milled for 20 hours or longer and stirred. If the wet ball mill time is less than 20 hours, the mixing may not be performed well.

The step of preparing the support powder is a step of drying the mixture at 50 to 60 캜. The pulverization and drying step (S120) is performed after completion of the aluminum oxide, carbon black and binder mixing step (S110), drying at 50 to 60 DEG C for removing acetone, pulverization with agate, and then finely uniform powder It is a step of filtering with a sieve of 100 μm to make.

Fig. 3 is a drawing showing the application of pressure by placing aluminum oxide, carbon black and binder mixed powder according to the present invention into a circular metal mold. The support forming step is a step of putting the support powder into a metal mold and applying a pressure to manufacture a support. After the grinding and drying step (S120) is completed, the support forming step S130 is performed by putting the powders 1 to 5 g that have been pulverized in the circular metal mold, as shown in FIG. In this case, when the pressure is excessively increased, the support may be warped or broken. Therefore, a pressure of 2 to 5 bar is applied for 10 seconds to prepare a support having a diameter of 30 mm and a thickness of 2 mm.

4 is a view showing a heat treatment process for removing the carbon black and sintering the support according to the present invention. In the pore-forming step, the support is heat-treated at 700 to 1100 ° C to remove the carbon black to form pores. Carbon black is removed in the form of carbon dioxide through the combination of carbon and oxygen. When the heat treatment temperature for pore formation is less than 700 ° C, thermal energy for bonding carbon and oxygen is insufficient, and when the temperature is higher than 1100 ° C, sintering of the support is performed and carbon black removal becomes difficult. The heat treatment step (S140) for pore formation and support sintering is a heat treatment step for forming pores through the removal of carbon black and sintering the support after completion of the support forming step (S130). As shown in FIG. 4, the temperature was maintained at 700 to 1100 ° C. for 7 hours and 5 minutes and then maintained for 1 hour in order to prevent the substrate from bending. 15 to 35 parts by weight of carbon black and 0.1 to 2 parts by weight of the binder are removed through the heat treatment, so that only aluminum oxide is left in the support. In the heat treatment process for sintering the support, it was maintained at 1100 ~ 1500 ° C for 3 hours and cooled slowly for 12 hours to prevent brittleness of the support due to rapid cooling. When the heat treatment temperature for supporting sintering is less than 1100 ° C, sintering is not performed due to insufficient heat energy, and when the temperature exceeds 1500 ° C, the support may melt.

It can be easily impregnated with the pores of the nano unit and is excellent in color development and excellent in durability and the catalyst can be penetrated into the pores of the nano unit so that the environmental pollution problem due to the waste water caused by the catalyst being dropped can be prevented in advance.

7 is a flow chart illustrating the preparation of the catalyst according to the present invention and the catalyst impregnation step (S200) of the support. The preparation of the catalyst and the impregnation of the support according to the present invention include distilled water, a copper nitrate hydrate mixing step, a catalyst impregnation step of the support, and a drying step. After the support is prepared, a catalyst is prepared as shown in FIG. 7, and the support is impregnated with the catalyst.

Distilled water, copper nitrate cuprate, cobalt nitrate hydrate and manganese nitrate (S210) is a step for preparing a catalyst for color rendering. In the case of blue and cobalt blue series, 0.1 to 3 parts by weight of copper nitrate (CuN ₂ O ₆ .3H ₂ O) in which blue color is developed after heat treatment is added to 100 parts by weight of distilled water, and cobalt nitrate cobalt hydrate (CoN ₂ O ₆ .6H ₂ O) and 1 to 5 parts by weight of manganese nitrate (MnN ₂ O ₆ ), which is black-colored after heat treatment, for producing a rich and clear color.

The catalyst impregnation step (S220) of the support is a step of impregnating the support to the weighing dish after completion of the catalyst preparation step (S210) for 1 minute.

The drying step (S230) is a step of heat-treating the support impregnated in the catalyst at 50 to 60 DEG C for 1 hour after completion of the catalyst impregnation step (220) of the support.

Finally, the color development step is a step of drying the impregnated support and then heat-treating the impregnated support at 1000 to 1200 ° C to develop hue on the support.

FIG. 9 shows the expression according to the heat treatment temperature condition according to the present invention and shows the appearance of blue and cobalt blue colors at 1000 to 1200 ° C. The heat treatment step (S300) for color development is a step of heat treatment for color development after completion of the drying step (S230). As shown in Fig. 9, the heat treatment was maintained at a temperature of 100 to 1200 DEG C for 2 hours. When the heat treatment temperature for color development is less than 1000 ° C, oxidation of the catalyst is not actively performed, and when it exceeds 1200 ° C, the catalyst may be dissolved. The oxidation of the catalyst at temperatures between 1000 and 1200 [deg.] C results in the appearance of blue and cobalt blue colors on the support.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

1. Manufacture of support with pores

Weight portion Aluminum oxide 100  Carbon black 20 bookbinder One

The support on which the pores were formed was manufactured by weighing as shown in Table 1. 20 parts by weight of the carbon black for forming pores and 1 part by weight of the binder for improving the formability were mixed with 100 parts by weight of the aluminum oxide powder (S110) to prepare a mixture. In the present embodiment, since aluminum oxide powder is fine, it is difficult to form a support, so 1 part by weight of a binder improving moldability is mixed. When the amount of the carbon black is less than 15 parts by weight, the number of pores is insufficient. When the amount of the carbon black is more than 35 parts by weight, the number of the pores is excessive and the support may be easily broken. Since the aluminum oxide powder is fine, it is difficult to form a support, so that a binder which improves the formability is prepared by mixing. When the amount of the binder is less than 0.1 part by weight, the mixture does not aggregate and the mixing is not good. When the amount of the binder is more than 2 parts by weight, the mixture may be cured. As the binder, a polyvinyl butyral resin which is an organic binder was used. Although the polyvinyl butyral resin has strong adhesion, it is weak against heat and can be easily processed by heat treatment.

Thereafter, acetone was added to the mixture, and the mixture was mixed with acetone at a ratio of 1: 3, followed by wet ball milling for 24 hours.

If the wet ball mill time is less than 20 hours, the mixing may not be performed well.

Then, the mixture was dried at 60 DEG C for pulverization and drying (S120), pulverized with agate, and then sieved with a 100 mu m sieve to form fine and uniform powder.

Fig. 3 is a drawing showing the application of pressure by placing aluminum oxide, carbon black and binder mixed powder according to the present invention into a circular metal mold. As shown in FIG. 3, 3 g of the pulverized powder was put into a circular metal mold and pressure was applied to form a support (S130). In this case, if the pressure is excessively increased, the support may be warped or broken. Therefore, a pressure of 3 bar is applied for 10 seconds to prepare a support having a diameter of 30 mm and a thickness of 2 mm.

Finally, pore formation through removal of carbon black and heat treatment to sinter the support (S140). As shown in Fig. 4, the substrate was heated up to 900 DEG C for 7 hours and 5 minutes, and then held for 1 hour in order to prevent the substrate from warping. Treated at 900 ° C to remove carbon black in the form of carbon dioxide through the combination of carbon and oxygen. When the heat treatment temperature for pore formation is less than 700 ° C, thermal energy for bonding carbon and oxygen is insufficient, and when the temperature exceeds 1100 ° C, sintering of the support is performed, which makes it difficult to remove carbon black. Through the heat treatment, 20 parts by weight of carbon black and 1 part by weight of the binder are removed, so that only aluminum oxide is left in the support. As a heat treatment process for sintering the support, it was maintained at 1300 ° C for 3 hours and then slowly cooled for 12 hours to prevent brittleness of the support due to rapid cooling. When the heat treatment temperature for supporting sintering is less than 1100 ° C, sintering is not performed due to insufficient heat energy, and when the temperature exceeds 1500 ° C, the support may melt.

FIG. 5 is a view showing pores formed by the above processes, and FIG. 6 is a photograph showing pores formed in a support manufactured according to the present invention. It can be easily impregnated with the pores of the nano unit and is excellent in color development and excellent in durability and the catalyst can be penetrated into the pores of the nano unit so that the environmental pollution problem due to the waste water caused by the catalyst being dropped can be prevented in advance.
