Description

Antibiosis with fixed thermal conductivity and coating method

The present invention relates to a device having an antimicrobial performance and a method for forming a coating layer thereof, and more particularly, by adding a powder having an antibacterial property to the coating layer boundary of the device and coating it selectively with heat treatment, thereby preventing the antibacterial and deodorizing of the device. The present invention relates to a device having an antimicrobial performance and a coating layer composition method thereof to improve the performance.

Of the common appliances that need to be coated on the surface, all instruments are generally made of metal, such as aluminum. Initially, the appliance itself has been used even with the metal itself. In order to prevent the problem such as scratching the surface of the device when cooking the same thing or in other cases, after the development of a mechanism for applying a coating liquid to the surface to form a coating layer on the surface has been developed In addition to various types of coating liquids, various types of coating layers were formed on the surface.

Among them, a primer coat, a mid coat, and a top coat are sequentially laminated on the surface of the apparatus, so-called three coatings forming a coating layer are commonly applied to the apparatus. Doing.

That is, as shown in Figure 1, the triple coating layer applied to the surface of the instrument is subjected to a primer coat 12 (undercoat) on the molded metal layer 11 and then subjected to the first heat drying operation, and again to a mid coat 13 (mid coat) After the second heating and drying, the coating surface is completely cured, and then the other mineral particles 14 are applied on the mid coat 13.

And it is manufactured by performing the top coat 15 (top coat) on the mineral particle 14 and the mid coat 13 again.

In addition, on the primer coat 12 or the midcoat 13, the coats of different colors are applied with the coats partially dried or sufficiently damp to form a discontinuous coat of continuous small spheres. The application of the top coat 1 5 led to the development of a coating layer in which the discontinuous coat was expressed as a multicolored pattern in the triple coating layer but slightly protruded to prevent the surface of the appliance from being scratched. It was typically applied to the organization.

By the way, in order to explain the coating layer, the coating layer of the kitchen appliance of the type described above was representatively selected, but in the end, all the coating layers of the surface of the apparatus remain only to protect the surface of the apparatus or express the aesthetic sense. Since the composition constituting the coating layer itself does not have a specific property to exert a special effect on the human body, in order to cook the food that a human ingests, the raw material of the food must be coated with the coating layer formed on the surface of the kitchen utensil.

First, as shown in Figures 2 to 5, the apparatus having an antimicrobial performance of the present invention and its coating layer composition method is as follows.

A primer coat 110, a mid coat 120 and a top coat 130 are sequentially stacked on the surface of the instrument 10 to form a three coat layer 100.

The granite diorite rock refers to igneous rocks rich in silicon oxide in chemical composition, and mineral composition is almost the same as granite. Peel-like tissue consisting of semifinished tablets of granules and stone of fine or neutral.

Mineral composition is almost the same as granite, but it is semi-structured and composed of semi-crystal of granulation and fine or neutral stone. Semi-crystal contains many crystals of quartz or potassium feldspar and contains a small amount of mica. Like granite, the stoneware itself is crystalline and granular, but much smaller. Granite rock is produced at the periphery of a fairly large granite body or as an independent rock.

Since granite diorite is the main component is silicic anhydride and aluminum oxide. Yellowish white is used as filter, anti-inflammatory and so on. It is called weak stone. It emits far infrared rays and is applied to jjimjilbang, tableware and medical equipment.

Particularly, granulocythemia is also called as a medicinal stone. In the past, it was used as an anti-inflammatory agent for treating skin diseases such as swelling or boils.

The granulophyllite is composed of 3 to 150,000 holes per cubic centimeter, which is highly adsorptive and contains about 25,000 inorganic salts.

Moreover, it acts as a toxic metal remover because it functions to exchange ions with heavy metals, and heat is emitted to the rock to emit far infrared rays.

The apparatus of the present invention, which is applied to the cooking of foods by using the properties of granite chlorophyll, has a strong adsorption effect, so it adsorbs heavy metals such as Cd and Hg, residual chlorine, E. coli, and radioactive substances, and thus, bacteria generated in kitchen equipment. Removal can be done quickly.

In addition, far-infrared emission may proceed more easily because it is directly exposed to heat when used for food cooking.

Such, the antibacterial device of the present invention by selectively coating the antimicrobial powder having antibacterial, sterilization and deodorizing function on each coat layer boundary, to ensure the eradication of bacteria, deodorizing performance of each coat, after cleaning the instrument It can perform antibacterial and deodorizing function within 2 hours.

In order to prove such an effect, the apparatus having the antimicrobial performance of the present invention was commissioned by the Korea Institute of Construction Materials, and the results of the antimicrobial performance after incubation with E. coli strains are shown in Table 2 below.

As shown in [Table 2], after the culture of Escherichia coli Escherichia coli ATCC 25922 in the initial concentration of 839 CFU / 70p on the surface of the apparatus and anti-bacterial bacterium having a bactericidal performance of the present invention at the initial concentration of 839 CFU / 70p As a result of testing by the method (KICM-FIR-1003), after 2 hours, the same result as the initial concentration was measured in the normal sample (BLANK).

On the contrary, it can be seen that the apparatus having the antimicrobial performance of the present invention reduced the concentration of the used strain to 1CFU / 70p after 2 hours at the initial initial concentration of 839 (CFU / 70p).

As a result, in the general sample, while the bacterial reduction rate was 0%, the apparatus having the antimicrobial performance of the present invention showed a 99.9% bacterial reduction rate by the antibacterial powder.

In addition, the antimicrobial powder applied to the apparatus having antimicrobial performance can further maximize the antibacterial and deodorizing performance by adding tourmaline.

Here, tourmaline is a borosilicate having a hexagonal columnar crystal and refers to a natural mineral belonging to a hexagonal system.

The tourmaline is also known as tourmaline because the crystal itself generates electricity, and has only permanent electrical properties among the minerals present on Earth.

This is also called a polar crystal, and this ore generates negative ions and weak currents and far infrared rays generated by itself. For this reason, the tourmaline crystals have positive and negative electrodes at both ends of the crystals, no matter how small they are crushed, and they have electrodes that do not decay permanently unless heated near 1000 ° C. to be.

Here, when the positive and negative poles of the tourmaline crystal are connected, a weak current of 0.06 mA flows.

Such tourmaline generates negative ions and far infrared rays of 4 to 14 (μm) growth rays due to adsorption and repulsion, so that even if the smell of food to be cooked is adsorbed on the surface of the appliance to generate odors, dl cations and anions are combined. As a result of the electrical odor, the odorless odorless (odorless) phenomenon occurs, it is possible to more effectively exhibit the deodorizing function of the antibacterial powder.

In addition, the tourmaline has the effect of removing not only the smell soaked on the surface of the device but also the smell of floating in the room.

Moreover, the tourmaline increases the radiation amount to the far infrared rays by applying heat from the outside. This is the same as the properties of granite calculocarcinoma has the effect of increasing the far-infrared emission by heat even in the cooking process through the apparatus having antibacterial performance.

Finally, the present invention by selectively coating the antimicrobial powder having antibacterial, bactericidal and deodorizing function on each coat layer boundary by using granite diorite rock and tourmaline ore having antibacterial and deodorizing function, the bacterial eradication and deodorizing performance of each coat is improved. It can be ensured, and within two hours after the cleaning of the instrument to perform the bactericidal function quickly, there is an effect that can deodorize the surface of the appliance or deodorant of the food to be cooked.

Here, the antibacterial powder is usually made in the form of a powder and the size is made of a size of 0.05μ ~ 5μ.

This, while diversifying the shape of the powder to add the aesthetic effect of the antimicrobial coating layer coated on the surface of the instrument, and through the antimicrobial powder of the thin film having a wider to ensure more improved antibacterial and deodorizing effect.

The composition and composition ratio of the three coating layer are as follows.

The composition ratio of the coating solution of the primer coat 110 is 16.8 wt% of the nmp soluble mixture of polyamide, 4.1 wt% of water, 67.2 wt% of PTFE dispersion, 3.5 wt% of carbon black dispersion, and 8.4 wt% of silica dispersion.

The coating solution of the mid coat 120 is composed of PTFE dispersion, water, aromatic hydrocarbon, triethylamine, oleic acid, surfactant, carbon black dispersion, mica, and composition ratio.

The composition ratio of the mid coat 120 coating solution was 81.5 wt% PTFE dispersion, 9.22 wt% water, 3.14 wt% aromatic hydrocarbon, 0.46 wt% triethylamine, 0.46 wt% oleic acid, 0.33 wt% surfactant, 3.35 wt% carbon black dispersion The composition ratio is 1.54% by weight of mica.

In addition, the coating liquid of the top coat 130 is composed of the composition and proportion of PTFE dispersion, water, aromatic hydrocarbon, triethylamine, oleic acid, surfactant, mica.

The coating liquid composition ratio of the top coat 130 is 89.25 wt% of PTFE dispersion, 6.53 wt% of water, 1.09 wt% of aromatic hydrocarbon, 0.32 wt% of triethylamine, 0.32 wt% of oleic acid, 0.25 wt% of surfactant, and 2.24 wt% of mica. We do it with ratio.

As described above, the antimicrobial powder contains 2 to 3 parts by weight based on 100 parts by weight of the coating liquid of each of the primer coat 110 or the mid coat 120 or the top coat 130 having a blending ratio.

In addition, the primer coat 110, the mid coat 120, and the top coat 130 laminate may be produced in various embodiments.

That is, the antimicrobial coating layer 140 may be formed by applying an ink pigment containing antimicrobial powder or antimicrobial powder directly onto the primer coat 110 except for the mid coat 120 and the top coat 130.

Alternatively, the antimicrobial coating layer 140 may be formed by applying an ink pigment containing an antimicrobial powder or an antimicrobial powder directly on the mid coat 120 without the top coat 130.

Alternatively, the antimicrobial coating layer 140 may be formed by applying an antibacterial powder or an ink pigment containing an antimicrobial powder on the top coat 130 laminated on the primer coat 110 and the mid coat 120.

In this way, the surface of the apparatus 10 is laminated with three coatings 100 or each coat 110, 120 and 130, and then the antimicrobial powder 140 is formed by an ink pigment containing antimicrobial powder or antimicrobial powder.

The thickness of the antimicrobial coating layer 140 protruding together with the thickness of each coat of the three coating layer 100 is about 10㎛.

Here, the antimicrobial coating layer 140 may be formed on the mid coat 120 of the coating layer consisting of a primer coat 110 and the mid coat 120, or may be formed on the top coat 130 of the coating layer consisting of a primer coat 110 and a top coat 130. Could be

In addition, the above three coating is only one embodiment, it can be applied to apply the antimicrobial powder to water-based fluorine resin 1 coating, fluorine resin 2 coating, fluorine resin 3 coating and multi-layer coating, such as various coatings The antimicrobial coating layer to be applied is added one of the composition constituting all the paint products for forming the coating layer, that is, silicone oil paint, oily fluorocarbon resin paint, ceramic paint and the like.

In addition, the thickness of the three coating layer 100 coated on the surface of the mechanism 10 should be about 35㎛ or more as a whole to improve the durability can be used for a long time, but in reality, because of the relationship between the thickness of the curved surface of about 20㎛ Three-coat layer 100 is formed in a thickness to increase the defective rate.

Since this leads to a problem of lowering the productivity, when the ink pigment is applied on the top coat of the three coating layer 100 to form the discontinuous coating 140, the three coating layer 100 and the ink pigment to form a coating layer with a thickness of 40 μm or more. As the durability is improved, the defect rate is reduced and productivity is improved.

In addition, the antimicrobial powder having an antimicrobial function contained in the ink pigment is included, so that bacteria generated before and after washing can be quickly extinguished within 2 hours.

In addition, the ink pigment dispersed on the top coat 130 of the three coating layer 100 is applied in the form of spots are 86.8% by weight of PTFE dispersion, 3.38% by weight of water, 0.56% by weight of aromatic hydrocarbons, triethylamine, 0.17% by weight, oleic acid 0.17% by weight %, 0.12 wt% surfactant, 8.8 wt% inorganic pigment dispersion.

A method of forming a coating layer on the surface of the apparatus 10 using the primer coating liquid, the mid coating liquid, the top coating liquid and the ink pigment having the composition and composition ratio as described above is as follows.

Firstly, the surface area is increased by a sand blasting process in which a number of fine embossings are formed on the surface of the apparatus 10 to be coated in the first step.

The second step is to clean the surface of the sandblasted instrument 10.

In the third step, the primer coating solution is applied to the surface of the sandblasted and washed apparatus 10 to a thickness of 10 to 12 μm to form a primer coat 110, and then heat-treated at 200 ° C. for 15 minutes.

In a fourth step, the mid coat liquid is applied to the primer coat 110 applied on the surface of the apparatus 10 to a thickness of 10 to 12 μm to form the mid coat 120.

In the fifth step, the top coat liquid is coated with a thickness of 8 to 12 μm while the mid coat 120 is wet to form a top coat 130, and then the three coat layer 100 is completed by heat treatment at 300 to 350 ° C. for 15 minutes.

After the dried top coat 130 or the mid coat 120 of the three coating layer 100 is coated, an antimicrobial powder is added or an ink pigment containing an antibacterial powder is applied to the mid cord 120, and then the antimicrobial coating layer 140 is formed. Heat-process for 20 minutes at 415 degreeC.

Here, the application of the antimicrobial powder is the antimicrobial coating layer 140 applied to the ink pigment after the heat-treated mid coat 120 or top coat 130 coating is completed by heat treatment.

Alternatively, before the heat treatment may be applied by coating an ink pigment containing an antimicrobial powder or an antimicrobial powder on the top coat in a wet state and heat treatment at 405 ~ 415 ℃ for 20 minutes.

In particular, by including a transparent discontinuous coating layer on top of the antimicrobial powder applied on the top coat 130 to protect the antimicrobial coating layer.

In the mechanism 10 according to the coating layer composition method described above, the antimicrobial coating layer 140 of the ink pigment is formed on the top coat 130 of the three coating layer 100, but is not necessarily limited thereto. After the coating layer is formed, the discontinuous coating 140 of the ink pigment may be formed by the composition method as described above directly on the mid coat 120 without the top coat 130.

Alternatively, the antimicrobial coating layer 140 may be formed by the composition method as described above on the top coat 130 after forming the coating layer only with the primer coat 110 and the top coat 130 except for the mid coat 120.

In addition, in the coating layer composition method, the antimicrobial coating layer 140 is formed while the mid coat 120 or the top coat 130 is dried, but this is not necessarily limited thereto, and in some cases, the mid coat 120 or the top coat may be formed. The antimicrobial coating layer 140 may be formed while 130 is wet.

When the method is applied, the size of the antimicrobial coating layer 140, that is, the size of the spotter is relatively smaller than that applied in the dried state is applied for controlling the size of the antimicrobial coating layer 140.

By the way, although the surface 10 is coated by way of example as shown in the drawings, but representatively may be applied to the kitchen utensil 10 that the food mainly touches the surface, in addition to the need to coat the surface Applicable to all instruments 10 present.
