Description

A joint composition embodying a chameleon color and a joint construction method using the same

The present invention relates to a joint composition embodying a chameleon color and a joint construction method using the same, and more particularly, it is made of a member including Zion pigment in a main material including polyurea powder and a curing agent, and the critical range of temperature sensitivity is Different Zion pigments realize a gradual or instantaneous color change depending on the ambient temperature, and are useful for interior and building exterior applications where tiles are applied. It relates to a joint composition embodying a chameleon color having a color expression effect and a joint construction method using the same.

Tiles are widely used as excellent interior materials for houses, shopping malls, buildings, saunas, etc. as well as exterior exteriors of buildings, which are used as a method and means to create differentiated values of each building such as luxury, sensibility, sophistication, and artistry for people. is becoming

For people, luxury, sensibility, sophistication, and artistry are factors that are constantly changing, and the emotional feelings they want and accept vary according to the constant surrounding environment such as temperature, humidity, and season.

In addition, as the quality of life of mankind increases, interest in culture increases, and human sensibility is recognized as a more important factor.

However, conventional tiles exist as a simple exterior function, and have limitations in expressing access to human sensibility and differentiated values, such as displaying only fixed colors and patterns. As interest in the effect increases, methods for construction with various colors have been proposed.

As an example, Patent Document 1 discloses a special place in contact with water such as a bathroom or sauna, hot water, cold water, and the inside or outside of a general building using tiles, in existing commercial tiles used for differentiated interiors and exteriors, A means for recognizing the temperature of the commercial tile is provided, wherein the means for recognizing the temperature provides a color-changing tile formed of a blending material including a Zion pigment or a Zion pigment that changes color depending on the temperature. However, the method applied to tiles has a disadvantage in that the construction step is complicated and the unit cost is high.

In addition to the above bathrooms, tiles are used for verandas, kitchens, living rooms, interiors throughout the house, and exteriors of buildings. In terms of visual and convenience, the rate of using tiles in all spaces of a building is increasing, and when tiles are used, joint construction is essential to fill the space between them.

Tile joint construction is an operation to fill a very narrow gap (about 1 to 3 mm) between tiles with filler, and the clean aesthetics of tiles such as various molds and scales are greatly damaged by tile joint contamination contaminated by use. . In this case, in general, the entire tile is reconstructed, which causes a great economic loss. In particular, conventionally released products are limited to white, gray, and cement components, so there are many disadvantages that do not stand out in the consumer's choice. In order to improve this problem, Patent Document 2 discloses a non-yellowing solvent-free epoxy color tile joint repair agent using metallic powder pearls.

It is composed of liquid type or plaster type (putty type) and is used for all tile joints such as lobbies, hallways, verandas, bathrooms, and living rooms. It is reported that various contamination and cracking of joints can be prevented in advance by construction, and the aesthetics can be made beautiful and splendid by adding metallic powder (shiny pearl) of each color to match the color of the tile body.

However, in the present invention, color expression is limited to a metallic powder of a predetermined color, and thus its utility is low for interior and exterior uses using the non-yellowing solvent-free epoxy color tile joint repair agent using the metallic powder pearl.

Accordingly, the present invention, as a result of efforts to improve the conventional problems, is made of a member including a Zion pigment in a main material including polyurea powder and a curing agent, and in particular, by including Zion pigments having different critical ranges of temperature sensitivity, It implements a gradual or instantaneous color change according to And by confirming the multi-color expression effect, the present invention was completed.

Hereinafter, the present invention will be described in detail.

The present invention provides a joint composition in which a chameleon color is implemented, comprising a member including Zion pigment on a main material including polyurea powder and a curing agent.

In the joint composition of the present invention, polyurea is used as the main ingredient among the materials applied to the general joint composition.

The polyurea is produced by a chain reaction of isocyanate prepolymer and polyetheramine, and has a gel-time of 15 to 25 minutes, and a very fast curing rate, including the Zion pigment of the present invention. It can improve the workability of the joint composition and at the same time serves as a binder that binds the components together. In addition, polyurea has excellent workability, does not emit volatile organic compounds (VOCs), and is harmful to the human body even in water. It is eco-friendly because no components are eluted, and has excellent tensile strength, tear strength, durability and chemical resistance.

In addition, due to the excellent salt water resistance of polyurea, the joint composition of the present invention mainly containing polyurea is advantageous not only for the interior of the building, but also for the exterior of the building, including marine facilities, seawater desalination facilities, and convenience facilities using seawater. .

The curing agent used in the joint composition of the present invention is a component capable of curing the main material made of polyurea, and an amine-based mixture is preferably used. It is preferable to use any one selected from the group consisting of aliphatic polyamines, modified aliphatic polyamines and aromatic amines as the amine-based mixture.

The joint composition embodying the chameleon color of the present invention changes color according to the ambient temperature, and is implemented from the member components including the Zion pigment. More preferably, it contains a member containing at least two or more types of mixed Zion pigments.

At this time, the Zion pigment is a pigment that changes color depending on the temperature, and the color is expressed as the reference temperature is reached, and the reversible or irreversible Zion pigment is classified according to whether the color returns to the original color when the temperature is lowered again.

Accordingly, the joint composition embodying the chameleon color of the present invention contains a reversible Zion pigment, and more preferably, is used in a mixed form of at least two or more.

The reversible Zion pigment has a metal complex salt, a corellic liquid crystal, or a metamo color. At this time, the Zion pigment can use the principle of having a unique color below the reference temperature, and becoming white or transparent above the reference temperature, and the effect can be obtained by changing the reference temperature.

Specifically, when a black pigment with a reference temperature of 20 °C is a pigment that changes to transparent or white (background color) at 20 °C or higher, it appears black in an environment where the room temperature is 10 °C, but turns transparent or white at 20 °C or higher. When the temperature is 30°C, it is transparent or white at room temperature, and when it drops below 20°C, the original color appears.

In addition, the Zion pigment of the present invention is a reversible thermosensitive pigment that appears in color at low temperature and loses color at high temperature, or has no color at low temperature and shows color at high temperature.

The Zion pigment has a difference in the critical range of temperature response according to the production process, and the reversible Zion pigment may have a critical range of the reference temperature response controlled at -15 to 70°C.

The Zion pigment according to the present invention uses a mixture of two or more types having different critical ranges of temperature sensitivity, and black, blue, red, and yellow are used, and the remaining colors can be implemented by mixing general inks or pigments. At this time, when determining the color, pay attention to the background color painted with general ink.

If the background color is dark and the Zion pigment is bright, the hiding power is lowered and the background color protrudes. If the background color is white, it can be used without restrictions.

Specifically, if the background color is painted red with general ink and then applied with dark blue, it is dark blue at room temperature and red when the temperature rises, thereby realizing a dual color effect.

When a joint composition containing such a pigment combination is applied to a bathroom, when the red color appears as the bath temperature rises from blue at room temperature, it is possible to visually confirm that the appropriate temperature has been achieved. It can help stimulate interest in washing face and bathing.

In the joint composition of the present invention, the Zion pigment is used in a mixed form of at least two or more to realize a chameleon color.

In this case, the Zion pigment is included in a mixed form of at least two or more types having different critical ranges of temperature sensitivity.

The temperature sensitive critical range of the Zion pigment does not deviate from the temperature limit point at which the Zion pigment loses its function, and it is characterized in that different colors are expressed for low, medium, and high temperatures.

Therefore, the joint composition containing the Zion pigment of the present invention differs by different combinations of the critical ranges of temperature sensitivity for two or more mixed types of Zion pigments, and the reference temperature is divided into 10°C, 20°C, 30°C, and 40°C. You can make it change color.

Specifically, it is possible to detect changes according to temperature by mixing different pigment colors for better visibility, such as blue at 10°C, yellow at 20°C, orange at 30°C, and red at 40°C. have.

1 is a schematic diagram of a combination of two colors of Zion pigment, and when Zion pigments of two colors are added to the background color, it is possible to implement the characteristic of changing to three colors including the background color in response to temperature.

The Zion pigments of the two colors to be added may have different critical ranges of temperature sensitivity, respectively. In FIG. 1, the Zion pigments sensitive to a temperature of 31° C. and 26° C. are selected and combined.

FIG. 2 is a schematic diagram of a combination of three colors of Zion pigment, and provides an embodiment of a combination of three colors of Zion pigments having different temperature responsive ranges to a background color.

Specifically, by combining 20 ° C Zion pigment, 30 ° C Zion pigment, and 40 ° C Zion pigment, the color changes at 20 ° C, changes to another color at 35 ° C, and changes to another color when it rises above 45 ° C can

3 is a schematic diagram for a combination of three or more colors of Zion pigment, and provides an embodiment of a combination of Zion pigments of four colors having different temperature responsive ranges to the ground color.

At this time, in combining the Zion pigments having different critical ranges of temperature sensitivity, the Zion pigments representing each color are designed to have a temperature deviation of at least 4° C. or more. When the temperature deviation is less than 4° C., the color change width responsive to ambient temperature conditions is narrow, so visibility is not good, and there is a disadvantage in that a visual effect due to a definite color change is lowered.

The joint composition of the present invention consists of 70 to 90% by weight of a main material containing polyurea powder and a curing agent, and 10 to 30% by weight of a member containing a Zion pigment, and the content of the Zion pigment can be adjusted according to the degree of color depth. However, it is preferably contained in an amount of 1 to 10% by weight, more preferably 5 to 10% by weight.

The remaining component components other than the Zion pigment may include 3 to 10% by weight of pearl powder, 3 to 5% by weight of a deodorizing and antibacterial functional material, and 3 to 5% by weight of a UV blocker, and to be contained within the content of the component. can

In addition to the Zion pigment, pearl powder may be further included in the member component.

Pearl powder is an additive capable of providing a shiny effect, and can be selected from various well-known pearl powders such as silver pearl, gold pearl, and pearl pearl. In particular, the color of the joint changes depending on the viewing angle by sunlight or light by giving it a natural aluminum color or gold color, and through this, you can feel splendid and beautiful.

Therefore, preferably, it can be used selectively from materials that can implement a sparkling pearl effect, such as glitter powder, aluminum powder, aluminum paste, fluorescent pigment, photoluminescent pigment, metal oxide, and the like.

In addition, the member component of the present invention may further include a deodorizing and antibacterial functional material in addition to the Zion pigment and pearl powder.

In the case of the joint composition, it looks clean aesthetically when first applied, but over time, various contaminations adhere to it and become aesthetically dirty. It is difficult to return to the original state.

Moreover, the joint composition embodying the chameleon color of the present invention should be implemented with the color due to the Zion pigment without contamination.

Accordingly, the deodorizing and antibacterial functional material used in the present invention is an additive contained for the purpose of preventing various bacteria and fungi, and the organic antibacterial agent is inexpensive and has good antibacterial activity at the beginning, but the effect decreases over time and there is a controversy over the harmfulness, Inorganic antibacterial agents are expensive and have weak initial antibacterial power compared to organic ones, but have semi-permanent effects and are harmless to the human body, so it is generally preferable to use a mixture of an organic antibacterial agent mixture and an inorganic antibacterial agent.

As a material having a deodorizing function, a material having excellent adsorption power against bad odors such as loess can be used.

The inorganic antibacterial agent can be selected from zeolite-based inorganic antibacterial agents, silver ion-based inorganic antibacterial agents, and nano-ized selenium inorganic antibacterial agents. In particular, zeolite-based inorganic antibacterial agents are made of metal oxides such as _{silicon oxide (SiO 2} ) and aluminum oxide (Al ₂ O _{3 ).} However, it can be adsorbed to the protein layer of the fungal cell membrane to produce a strong sterilization effect.
