Description

{ECO-FRIENDLY CERAMIC HIGH PERFORMANCE COATING}

The present invention relates to an eco-friendly ceramic heavy construction method, more specifically, to a method of manufacturing an eco-friendly ceramic heavy construction method, The amount of volatile organic compounds and secondary pollutants generated during the coating process can be significantly reduced, thereby minimizing the deformation of the coating film and shortening the drying time The present invention relates to an eco-friendly ceramic heavy construction method which can be efficiently used in various fields.

 In the case of metal structures, it is common to protect the surface of the metal by coating the bottom, middle, and top surfaces. In the case of metals used as general building materials, there is almost no use of metal due to high corrosion occurrence, and corrosion is suppressed by using a coating agent such as zinc plating, aluminum, asphalt, polymer, and high-rigidity concrete. In particular, in the case of metal for building structures and metal structures used for construction and plants, it is common to use zinc plating or an aluminum coating agent to suppress the occurrence of corrosion.

     However, in the case of such a corrosion inhibiting coating agent, there is a disadvantage that the function as a coating material is insufficient although the function of suppressing corrosion is sufficient. Most corrosion inhibiting coatings have significantly lower adhesion to epoxy based coatings and topcoatings used in conventional heavy duty coatings.

     This is due to the fact that existing corrosion inhibiting coatings concentrate solely on the functionality for inhibiting corrosion and can not fully utilize the functionality as a coating.

In addition, the intermediate and topcoating agents used in the heavy-wall construction method are applied to the interior and the exterior of the building, and developed in various forms according to the purpose of use and application site, and can be broadly classified into oil-based paints and water-based paints. In general, water-based paints are used in sites where the interior of environment and environment are particularly required because of their excellent environment-friendly properties. The oil-based paints are excellent in physical properties such as scratch resistance, stain resistance and chemical resistance, And the like.

In recent years, environment-friendliness has become an issue in the field of paint due to an improvement in living standards and an increase in interest in health and the environment. Accordingly, it is possible to combine the environment-friendliness of water- Technologies are being developed.

These technologies are mainly characterized in that a hydrophilic binder is mixed with a solvent-based paint made of a conventional urethane resin or epoxy resin to reduce the amount of volatile organic compounds emitted during drying after coating.

However, this is only a partial reduction of the amount of volatile organic compounds emitted after the coating is applied, and does not show a direct reduction effect on the essential pollution source of the paint.

In the case of paints, not only the volatile organic compounds generated during drying after application of the paint but also the secondary particles generated due to various weathering effects due to the fine coating of the coating film and the secondary particles generated by the coating film damage due to various exhaust gases, Pollution causes more serious problems. However, there is no practical solution to the reduction of pollutants in the secondary pollution.

Further, as an eco-friendly natural paint, an eco-friendly paint powder (Patent Document 1) comprising water-soluble adhesive powder such as loess, diatomaceous earth, charcoal powder and resin powder, filler powder and additive powder (Patent Document 1), a first functional additive and a second An external natural paint having high elasticity added with a functional additive to a natural resin composition (Patent Document 2), and the like are known.

However, such natural paints have problems such as scratch resistance, stain resistance and chemical resistance, and are easily peeled when they are exposed to external impact or strong ultraviolet rays for a long time or have a large temperature difference.

On the other hand, the existing heavy-duty method includes a step of applying a water-based epoxy-based rust-preventive paint comprising a surface treatment step, a base and a hardening agent, and a water-based urethane-based rust-preventive paint applying step (Patent Document 3 ) Are known.

However, there is still a need to develop a new environmentally friendly heavy-duty method that simultaneously improves corrosion resistance and adhesion as a paint, and further reduces environmental pollution not only after construction but also secondary environmental pollution to be.

In addition, by enhancing the functionality of the coating agent for corrosion inhibition as a coating, various colors can be applied to the corrosion inhibiting coating agent. When the intermediate agent is used on the undercoating agent applied in this manner, it is very easy to color the color applied to the design since the hiding agent required by the function of the intermediate agent is reduced by selecting the same series of colors as the undercoating agent. When the ratio of various raw materials used to express the color is reduced, the ratio of the other functional ingredients or the proportion of the resin can be increased accordingly.

As a result, the undercoating functional corrosion inhibitor can enhance the adhesive strength while suppressing the corrosion, and the adhesive force can be further improved as compared with the conventional products.

Further, by using a functional corrosion inhibitor as a primer and by using an environmentally friendly intermediate agent containing various functional powders, the solid content of the paint is greatly increased, and the amount of harmful volatile organic compounds generated during the coating process is remarkably reduced Thereby minimizing adverse effects on the human body and the environment.

In addition, according to the present invention, even in the secondary pollution caused by the damage of the coating film due to the fine powder and the various exhaust gases, which are produced by finely cutting the coating film due to various weathering actions after the formation of the coating film, Can be significantly reduced.

In addition, the coating film formed by the environmentally-friendly ceramic coating method according to the present invention is excellent in surface uniformity, and can exhibit excellent deformation resistance and uniform film quality even after a long period of time due to less occurrence of defects such as cracking and aggregation.

Further, according to the present invention, since the drying time can be remarkably reduced during the construction and drying process of the paint, the paint can be widely and efficiently applied to various construction sites because of its excellent workability.

According to the present invention, the cost competitiveness can be increased by using the ceramics pottery powder and the ceramic magnetic powder, which are wastes generated in the pottery making factory, and the whiteness of the pottery and the magnetite can be maximized, Various colors can be easily realized compared with resins such as epoxy and urethane.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, numerous specific details are set forth, such as specific elements, which are provided to aid a more thorough understanding of the present invention, and it is to be understood that the present invention may be practiced without these specific details, It will be obvious to those who have. In the following description of the present invention, a 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 eco-friendly ceramic heavy construction method according to the present invention comprises a functional undercoating agent having functions simultaneously as a coating while suppressing the occurrence of corrosion of a metal structure by constituting them by a subject and a sub-agent, and a method of significantly reducing volatile organic compounds And an eco-friendly intermediate agent capable of reducing the emission of secondary pollutants generated after the film formation. Hereinafter, the eco-friendly ceramic resin used in the present invention will be described first, since the eco-friendly ceramic resin is used as a sub-agent for the functional primer and the eco-friendly intermediate agent, and then the functional primer and the environmentally friendly ceramic eco-friendly method will be described.

- Environment-friendly ceramic resin

In the present invention, the eco-friendly ceramic resin used in the eco-friendly ceramic intermediate method as a sub-base of a functional primer and an eco-friendly intermediate agent includes: i) a powder mixture comprising silica fume, ceramic ceramic powder, ceramic magnetic powder and functional powder; And 10 to 40% by weight of a functional mixture comprising 100 to 500% by volume of water based on the total volume of the powder mixture; And ii) 60 to 90% by weight of a binder, wherein the functional powder is at least one selected from the group consisting of germanium powder, elvan powder, silica powder, volcanic stone powder and tourmaline powder, and the binder is at least one selected from the group consisting of silica gel, Wherein the powder mixture comprises 1 to 10% by weight of silica fume, 1 to 97% by weight of ceramic powder, 1 to 97% by weight of a ceramic magnetic powder based on the total weight of the powder mixture, 1 to 97% by weight and 1 to 97% by weight of the functional powder.

The eco-friendly ceramic resin used in the present invention can serve as a functional resin coating.

In the eco-friendly ceramic resin, the ceramic ceramic powder, the ceramic magnetic powder and the functional powder contained in the powder mixture have numerous innumerable micropores, and these pores adsorb and purify harmful substances. In order to maximize the functionality of such powders, a dried powder form is most preferable, but a powder form has a problem that it is difficult to use and handle and practicality is poor.

Generally, when a functional powder is mixed with a paint, it is common to mix a functional powder with a resin contained in most of the paint. When the paint is produced by this method, the paint formed has only superior functionality. Also, in this case, the functional powder is not completely uniformly mixed with the coating material and is often agglomerated, so that when the coating material is dried after the completion of the coating, the powder often falls off.

In order to solve such a problem, the ceramic powder, the ceramic magnetic powder and the functional powder are mixed with silica fume to be evenly distributed in this embodiment. When the water is mixed and stirred, water can be uniformly absorbed without agglomeration of the powder due to hydrophilicity of the silica fume.

Silica fume is ultrafine silica (SiO ₂ ) powder which is produced when metal silicon or a silicon alloy is produced, and is spherical in shape, and can be used as a high-strength and high-durability mixed material.

In the present embodiment, silica fume absorbs moisture to remove air contained in the functional powder having ultrafine pores to improve quality and life of the coating film, uniformly mix various functional powers contained in the powder mixture, Can be increased.

The content of silica fume is preferably 1 to 10% by weight based on the total weight of the powder mixture. When the content of silica fume is less than 1% by weight, miscibility with the functional powder is not sufficient and it may be difficult to obtain a uniform mixture, and excessive stirring time is required. And more preferably 1% by weight or more for effective working time. In addition, when the content of the silica material exceeds 10% by weight, absorption of water in the paint itself can be accelerated, and the life of the completely dried paint can be significantly affected.

Ceramic pottery powder and ceramic magnetic powder can increase the solid content in the eco-friendly ceramic resin and can act as an environmentally friendly paint. In addition, it is possible to enhance price competitiveness by using wastes generated in a pottery kiln factory, for example, wastes that are low in maturity or are destroyed and destroyed during processing.

In addition, in the case of conventional water-based paints, talc is added to the resin in order to impart a white color. In this case, there is a disadvantage that the adhesive strength is lowered and the quality is lowered.

In this embodiment, by using the ceramic pottery powder and the ceramic magnetic powder, it is possible to realize various colors more easily than conventional resins such as epoxy or urethane by increasing the degree of whiteness by making maximum use of the white of the basic index of ceramics and porcelain.

The ceramic pottery powder can be obtained by pulverizing a pottery made by firing kaolin at a temperature of 1100 DEG C or more and less than 1300 DEG C to a size of 50 to 300 mesh.

The ceramic magnetic powder can be obtained by pulverizing a magnet made by firing kaolin at a temperature of 1300 DEG C to 1350 DEG C to a size of 50 to 300 mesh.

At this time, wastes generated in pottery kilns as pottery or porcelain, for example, wastes to be discarded due to poor maturity, or wastes to be destroyed and destroyed during processing can be used.

The content of the ceramic ceramic powder and the ceramic magnetic powder is preferably 1 to 97% by weight based on the total weight of the powder mixture, and more preferably 50 to 80% by weight for more effective functionality. When the content of the ceramic pottery powder or the ceramic magnetic powder is less than the above range, the whiteness of the finished paint is insufficient and it is difficult to produce various colors of paints, and since the amount of solid content after completion of the paint is insufficient, There is a concern. When the content of the ceramic ceramic powder or the ceramic magnetic powder exceeds the above range, the amount of the solid content is too large, so that the functionality as a coating is deteriorated and it is not suitable for various external environments.

The functional powder can increase the solid content of the eco-friendly ceramic resin so as to function as an environmentally friendly paint. In addition, since these functional powders have ultrafine pores, they can absorb the moisture remaining in the inside or permeate from the outside after the formation of the coating film and can discharge them to the outside, and prevent damage due to various harmful substances penetrated from the outside It is possible to prevent the adhesion or penetration of contaminants, and can also exhibit a far infrared ray or anion emission effect.

The functional powder may be at least one selected from the group consisting of germanium powder, elvan powder, silica powder, volcanic stone powder and tourmaline powder.

Germanium powder is known to have far-infrared and anion-releasing effects, and can also exhibit deodorizing effect, air purification function, and antibacterial effect.

The elvan powder is excellent in the adsorption effect of harmful substances, has an ion exchange function with heavy metals, and has a far-infrared emission effect.

The silica powder has characteristics that are resistant to ultraviolet rays and various weathering effects, and can impart an adhesive force and strength to an environmentally friendly ceramic resin.

The volcanic stone powder has residual water absorption, far-infrared radiation effect, adsorption sterilization effect against harmful substances and bacteria.

Tourmaline powder has far infrared ray and anion emission effect, air purification effect, deodorization and sterilization effect, and metal corrosion prevention effect.

The content of the functional powder is preferably 1 to 97% by weight based on the total weight of the powder mixture, and more preferably 10 to 40% by weight for more effective functionality. When the content of the functional powder is less than the above range, it is difficult to sufficiently increase the solid content of the resulting paint, and it is difficult to sufficiently exhibit the effect of each functional powder. When the content exceeds the above range, There is a problem that it is difficult to uniformly mix.

Functional powders have ultrafine pores, so even when diluted with water, they contain certain air in the pores. Since the functional powder itself contains air and also has pores, it has a weak point that rust is generated and damaged by the condensation due to the temperature difference when the coating film is formed.

In order to solve such a problem, in this embodiment, the silica fume having excellent moisture absorption is mixed with the functional powder to remove the air remaining in the functional powder, thereby improving the quality and life of the coating film.

Next, 100 to 500% by volume of water is added to the mixing tank based on the total volume of the powder mixture, and the powder mixture is added while rotating.

In this case, it is preferable to rotate at a low speed at a speed of 10 to 50 rotations per minute, preferably 20 to 40 rotations per minute, so as to prevent agglomeration of the powder mixture and sufficiently mix with water.

The introduction of the powder mixture is preferably carried out gradually to prevent agglomeration of the powder and to form a homogeneous mixture.

- Environment-friendly ceramics Center type  Function for construction method Undergarment

Next, the functional undercoating agent for the eco-friendly ceramic heavy-duty method will be described.

The functional undercoating composition for eco-friendly ceramics according to one embodiment of the present invention comprises 50 to 80% by weight of a subject and 20 to 50% by weight of a sub-composition, By weight based on the total weight of the subtitles, 5 to 50% by weight of chromium, 5 to 30% by weight of nickel, 1 to 5% by weight of phosphorus, 20 to 80% by weight of aluminum and 5 to 50% by weight of polyamines, 5 to 30 wt% of aluminum, 5 to 30 wt% of aluminum, 50 to 80 wt% of bisphenol A type epoxy resin, 5 to 30 wt% of environmentally friendly ceramic resin, 5 to 20 wt% of acrylic emulsion resin, 1 to 5 wt% of UV absorber, % ≪ / RTI > by weight.

Conventionally, the undercoating agent used in the heavy-duty method has a function of cutting off the supply of oxygen and moisture so that corrosion does not proceed any more, and it is possible to suppress the occurrence of corrosion, but the strength for adhesion and surface protection is insufficient. Therefore, according to the conventional heavy-duty method, the undercoating agent exerts only the function of suppressing corrosion and maximizes the adhesive force of the intermediate agent, thereby improving the adhesive strength and the surface strength.

In the embodiment of the present invention, the undercoating agent used in the heavy-duty method is separated from the base and the sub-agent so as to sufficiently secure the function of suppressing the occurrence of corrosion, while enhancing the strength for adhesion and surface protection as a paint, It is possible to increase the property.

In the above examples, the subject may exhibit the effect of corrosion inhibition and rust removal, and the subordinate may exhibit an effect of enhancing adhesion and environment friendliness in the undercoating agent.

The subject matter is based on the total weight of the subject, from 4 to 25% by weight of zinc, from 5 to 50% by weight of chromium, from 5 to 30% by weight of nickel, from 1 to 5% by weight of phosphorus, from 20 to 80% %. ≪ / RTI >

When the content of each component contained in the subject is less than the above range, it is difficult to sufficiently exhibit the anticorrosive effect of the purpose of the subject matter, and when it exceeds the above range, there is a fear of deterioration of the physical properties.

Specifically, zinc has an action effect of preventing corrosion in air at room temperature. When the content is less than 4% by weight, there is a risk of occurrence of condensation or corrosion due to inflow of moisture from the outside, and more than 25% The ratio of the resin is relatively decreased, which may cause a problem in the adhesion of the paint itself.

The subject may be formed by blending each component at a low temperature at a low temperature.

Based on the total weight of the subtitle, 5 to 30% by weight of aluminum, 50 to 80% by weight of a bisphenol A type epoxy resin, 5 to 30% by weight of an environmentally friendly ceramic resin, 5 to 20% by weight of an acrylic emulsion resin, 5 wt% and 1 to 10 wt% UV stabilizer.

When the content of each component contained in the sub-component is less than the above-mentioned range, it is difficult to sufficiently exhibit the desired adhesive strength and eco-friendliness of the sub-product, and if it exceeds the above range, there is a fear of deterioration of the physical properties.

Particularly, when the content of the bisphenol A type epoxy resin is less than 50% by weight, it is difficult to obtain an excellent adhesion, and when it exceeds 80% by weight, the environmentally friendly property is deteriorated. If the content of the environmentally friendly ceramic resin is less than 5% by weight, the environmental friendliness of the undercoat agent is lowered, and if it exceeds 30% by weight, the economical efficiency is lowered due to an increase in cost.

UV absorbers and UV stabilizers can be used as commercially available raw materials for the manufacture of paints, examples of which include epoxy-based UV absorbers and stabilizers, and acrylic-based UV absorbers.

The sub-agent may further comprise a defoaming agent, a dispersing agent or a combination thereof.

The sub-agent may be formed by blending the respective components.

The functional primer for eco-friendly ceramics according to the present invention may contain 50 to 80% by weight of a subject and 20 to 50% by weight of a sub-material. When the content of the subject is less than 50% by weight, it is difficult to effectively inhibit the occurrence of corrosion. When the content of the subject exceeds 80% by weight, the content of the subtitle becomes too small, and the adhesive strength and the environment friendliness can not be sufficiently exhibited.

Furthermore, the coating operation can be completed within about 8 hours, so that it is possible to efficiently apply the working time and the labor cost.

After stirring was completed, the mixture was allowed to stand for 4 days and aged to form a functional mixture.

5% by weight of silica gel, 1% by weight of acrylic resin, 93% by weight of epoxy resin, and 1% by weight of natural resin were mixed based on the total weight of the binder to form a binder.

Then, 40% by weight of the prepared functional mixture and 60% by weight of the binder were mixed and stirred at low speed for 4 hours to prepare an eco-friendly ceramic resin.

(2) Functional evaluation of eco-friendly ceramic resin

The eco-friendly ceramic resin thus produced was evaluated for its functionality by comparing it to a conventional product (Unifox, KCC). The coating composition according to the present example was tested after further mixing 20% by weight of the epoxy curing agent based on the total weight of the coating composition. The test results are shown in Table 1. Comparative Example 1 is a test result of Unifox of a conventional product, KCC.

The eco-friendly ceramic resin of Example 1 Comparative Example 1 Drying temperature (캜) Touch dry time 40 minutes 90 minutes 10 ℃ Touch dry time 30 minutes 60 minutes 20 ℃ Curing Drying Time 14 hours 24 hours 20 ℃ Complete drying time 4 days 7 days 20 ℃

First, the solid volume ratio of the conventional product was about 40% (about 60% in the case of the high solid content product), but about 80% in the case of the coating film using the environmentally friendly ceramic resin of Example 1 . As described above, the eco-friendly ceramic resin of Example 1 significantly increased the solids content, thereby drastically reducing the drying time by more than 40% as compared with the conventional products.

Furthermore, it was confirmed that even when the green ceramic resin of Example 1 was painted twice (50 micrometers) after the lapse of 30 minutes after the touch-drying, the painted surface was uniform and no cracking or aggregation occurred. On the other hand, in case of existing products, in order not to cause coating irregularity, the re-coating interval should be at least 6 hours at the second coating.

Therefore, it can be confirmed that the environmentally-friendly ceramic resin of Example 1 has remarkably improved efficiency in terms of working time and coating film characteristics as compared with the conventional product.

Thus, in the case of the eco-friendly ceramic resin of Example 1, the solid content can be remarkably increased to reduce the generation of volatile organic compounds, thereby minimizing the deformation of the coating film state and reducing the secondary pollutant emission And can be efficiently applied to various fields by shortening the drying time.

During low speed rotation, the powder mixture was poured into the mixing tank little by little into water. After the addition was completed, the mixture was stirred slowly at a rate of about 30 to 60 times per minute for an additional 4 hours. At the time of stirring, 5 weight% of potassium alum was added and mixed based on the total weight of the powder mixture.

Then, 20% by weight of the prepared functional mixture and 80% by weight of the binder were mixed and stirred at low speed for 4 hours to prepare an eco-friendly ceramic resin.

(2) Functional evaluation of eco-friendly ceramic resin

The eco-friendly ceramic resin thus produced was evaluated for its functionality by comparing it to a conventional product (Moacote universal urethane from KCC). When the coating composition according to this example was applied, 20 wt% of urethane curing agent was further mixed based on the total weight of the coating composition and then tested. The test results are shown in Table 2. Comparative Example 2 is a test result of Moacoat Universal Urethane manufactured by KCC, which is a conventional product.

The eco-friendly ceramic resin of Example 2 Comparative Example 2 Drying temperature (캜) Touch dry time 30 minutes (depending on the situation, it can be repainted after touching and drying) 50 minutes 10 ℃ Touch dry time 20 minutes 25 minutes 20 ℃ Solidification drying time 8 hours 12 hours 20 ℃ Repainting interval After 4 hours (recommended) At least 12 hours 20 ℃

First, the solid volume ratio of the conventional product was about 40% (about 60% in the case of the high solid content product) but about 80% in the case of the coating film using the environmentally friendly ceramic resin of Example 2 . As described above, the eco-friendly ceramic resin of Example 2 significantly increased the solids content, thereby significantly reducing the drying time by 20% or more as compared with the conventional products.

Further, it was confirmed that even when the green ceramic resin of Example 2 was painted twice (50 micrometers) after the lapse of 30 minutes after the touch-drying, the painted surface was uniform and no cracking or aggregation occurred. On the other hand, in order to avoid film unevenness in the case of existing products, the re-coating interval at the time of 2 times of coating had to be at least 12 hours.

Therefore, it can be confirmed that the environmentally-friendly ceramic resin of Example 2 has remarkably improved efficiency in terms of working time and coating film characteristics as compared with the conventional products.

Thus, in the case of the eco-friendly ceramic resin of Example 2, the solid content can be significantly increased to reduce the generation of volatile organic compounds, thereby minimizing the deformation of the coating film state and reducing the secondary pollutant emission And can be efficiently applied to various fields by shortening the drying time.
