Description

Tile joint agent having color change according to temperature and its manufacturing method {TILE CORDS WITH COLOR CHANGES ACCORDING TO TEMPERATURE AND MANUFACTURE METHOD THEREOF}

The present invention relates to a tile joint agent having a color change according to temperature and a method of manufacturing the same, and more particularly, to a color according to temperature so that a fire in a building that is difficult to check with the naked eye because the color changes according to the temperature can be quickly indicated. It relates to a tile joint agent having a change and a method of manufacturing the same.

As the size and structure of modern buildings and civil engineering structures become larger and more complex, if a disaster such as a fire occurs, the damage to people and property inevitably increases. Due to such a complex structure, once a disaster occurs, lifesaving also suffers, and the damage becomes even greater.

When a disaster such as a fire occurs inside the building, firefighters must approach the fire point and extinguish it.If the fire point is closed by the door or it is difficult to enter the building itself, it is difficult to guess the size of the fire, making entry itself difficult. . In order to extinguish such fires, in the field of firefighting, equipment is being upgraded due to research and development on firefighting equipment, but there is a situation where there is some difficulty in terms of cost and dissemination.

In particular, in the case of a visible fire, it is possible to check it with the naked eye, so it is possible to respond quickly, but in the case of a fire occurring inside a building, it is difficult to check it with the naked eye, making it difficult to deal with a fire.

Many lives were lost due to a fire that occurred inside the building, not due to a visible fire, such as the last fire disaster at the Miryang Nursing Hospital and the Jecheon fire. As fire accidents occur frequently, fire-fighting laws are being reinforced accordingly, but since it is not applied to existing buildings, it is inevitable to increase the damage if a fire occurs in an old building.

Even if a fire alarm or sprinkler is installed in the building, it will be useless if the sprinkler does not work properly, such as the Jecheon Fire or the Miryang Nursing Hospital fire. Also, most of the fire alarms are turned off due to frequent malfunctions of the fire alarms.

Accordingly, recently, a luminous joint product has been released to help emergency escape by adding a luminous paint to the joints between tiles installed in the bathroom, living room, entrance entrance, lobby, etc. to emit light during power outages due to earthquake or fire. Luminous joints can be useful or decorative when going to the bathroom without actually turning on the lights at night, but they have no function to alert you to the danger of fire in the building.

FIG. 1 is a photographic view showing a color change according to temperature of polydiacetylene used in the present invention, and FIG. 2 is a graph showing a colorimetric response value according to thermal cycle of polydiacetylene in FIG. 1 And FIG. 3 is a graph showing the ultraviolet-visible spectrum of the polydiacetylene of FIG. 1.

Referring to FIGS. 1 to 3, polydiacetylene (PDA) is a conjugated polymer group and is a very interesting material from some viewpoints. First of all, these polymers are generally prepared by UV irradiation of self-assembled diacetylene supramolecules. Second, when PDAs are manufactured under optimal conditions, in many cases, they exhibit a dark blue color with a maximum absorption wavelength at 640 nm. Third, blue PDAs undergo color shift in the red phase (maximum absorption wavelength at 550 nm) according to environmental stimulation. The distinct blue-to-red color change of PDAs due to stimulation-induced stimulation has led to the development of various chemical sensors based on PDAs. The unusual color change has been adopted by various groups to develop temperature sensors, pH sensors and organic solvent sensors.

A common environmental stimulus that causes pre-discoloration transition of polydiacetylene is temperature. (A) to (D) of FIG. 1 show color changes with different colors at temperatures of 60°C, 80°C, 150°C and 200°C, respectively.

It is intended to minimize fire damage by notifying the risk of fire by manufacturing a tile joint agent using polydiacetylene, in which discoloration transition occurs due to such temperature stimulation.

Tile joints are fillers that are inserted in a space of about 1 to 3 mm between tiles and tiles in tile construction that is installed in a humid place inside a building, for example, toilets, baths, kitchens, and restaurants. By blending polydiacetylene in the composition of the tile joint, it can be prepared to have a color change function according to temperature.

4 is a flowchart illustrating a process of a method of manufacturing a tile joint agent having a color change according to temperature according to an embodiment of the present invention.

In Fig. 4, the powdery material of the tile joint material is mixed so as to be evenly distributed among the particles (step S410). In one embodiment, at least one of inorganic fine powder minerals, calcium carbonate, fibrous minerals, pigments, and inorganic antibacterial agents, which are powdery materials among the tile joint constituents, may be weighed at an appropriate weight ratio and then added to a blender to mix. .

After the lapse of a certain period of time, when the inorganic material is completely dispersed and mixed with each other, the liquid material among the materials constituting the tile joint agent is stirred (step S420). In one embodiment, a thickener, a dispersant, and a polyester-based silicone synthetic resin, which are liquid materials among the constituents of the tile joint agent, are weighed at an appropriate weight ratio and then stirred in a stirrer to make optimal properties suitable for mixing and construction.

The mixed powdery material and the stirred liquid material are mixed to form an emulsion (step S430). In one embodiment, a liquid bonding material is added to the mixed inorganic material, and the mixture is mixed for a certain period of time so as to be evenly dispersed and mixed in the inorganic material to prepare a general tile joint composition.

Here, the inorganic fine powder minerals among the general tile joint constituent materials are difficult to insert a rather large particle aggregate, since the distance between the tile and the tile is usually about 0.1 to 0.3 cm in the tile attaching construction. Since the reduction in the relative specific surface area may lead to a decrease in strength, an inorganic fine-powder mineral (silica sand, etc.) in a state in which an appropriate ratio is mixed with a 40-100 mesh particle size and a 100-250 mesh particle size by sieving, The total weight ratio should be 50.00~70.00% by weight.

Calcium carbonate (CaCO ₃ ) is an ultra-fine powdery mineral, and if a material with a specific surface area of 0.3 to 1.5 m ² /g with a particle size of 10 to 15 μm is properly used, workability is improved and inorganic Since it serves to increase the strength by efficiently filling the voids of the finely divided mineral, it is recommended to limit the amount of use within the range of 20.00 to 30.00% by weight of the total weight. If calcium carbonate is mixed with 20.00% by weight or less, the construction surface may be rough, and if it is mixed with 30.00% by weight or more, workability is deteriorated, and the relative mixing ratio of fine powder minerals, which is a durable binder, is reduced, resulting in a significant decrease in strength.

Calcium silicate can be used as the fibrous mineral, and calcium silicate forms a non-oriented network structure by mixing with the constituent when the constituent is bonded by a binder, thereby improving the bonding strength between the composition particles and the particles to form a fibrous bond. It is a crack inhibitor that plays a role and prevents micro-cracking and durability of finely divided minerals. The mixing amount is preferably mixed within the range of 1.00 to 5.00% by weight of the total weight. This is because excessive use results in poor workability and lower strength.

Thickeners are additives that control the physical properties of synthetic resin, which is a bonding material, and can improve workability and adhesion, so they play a role in making optimal properties suitable for construction. As a type, hydroxyethl cellulose or methyl cellulose can be selectively applied, and the cellulose derivative, which is a constituent material, is nonionic and has Newtonian fluid viscosity between pH 8 and 9 depending on the shear force of the aqueous solution. It serves to increase the viscosity. Since the mortar used for tile joint construction must be mixed with a thin kneader, the role of the thickener is important, and it is preferable to mix within the range of 0.20 to 1.00% by weight.

Dispersing agent is a liquid material used to disperse pigments to facilitate coloring. Sodium citrate or sodium triphosphate can be selectively used, and it is preferable to mix within 0.02 to 1.00% by weight, which is 0.02 If it is less than weight %, fine cracking and swelling occur, and if it exceeds 1.00 weight %, adhesion strength and durability are deteriorated.

The antibacterial agent is a non-toxic inorganic antibacterial agent in which an antibacterial metal is substituted on a zeolite carrier, and exhibits strong growth inhibition and killing ability through contact with bacteria.

Polyester-based silicone synthetic resin is a material obtained by copolymerizing silicone with synthetic resin as a binding material for the constituent materials, so due to the inherent water repellency of silicone, it excludes the habitat environment of mold bacteria caused by water intrusion, as well as the durability of tiles by intrusion of external water and evaporation It also plays a role of excluding the tile dropping phenomenon caused by this loss.

The above constituent materials are introduced into the mixer by weighing at an appropriate weight ratio. The inorganic fine powder mineral, which is a powdery material, and calcium silicate, calcium carbonate, and pigment are first added and mixed so that the particles are evenly distributed. After that, the liquid material, synthetic resin, thickener, and dispersant are stirred in another container to make appropriate physical properties, and then added to a mixer to complete an emulsion composition.

After polydiacetylene is added to the finished tile joint composition (step S440), it is stirred at room temperature for 6 hours so that it is well mixed (step S450), and the final finish is completed (step S460). In one embodiment, polydiacetylene is chromogenic and may exhibit a secondary chromogenic reaction upon exposure to a specific temperature. Here, polydiacetylene may be added in an amount of 5 to 10 parts by weight relative to 100 parts by weight of the tile joint composition.

In one embodiment, a bis-polydiacetylene-phenylene derivative represented by the following Formula 1 in which two polydiacetylene structures are connected to a p-phenylene group may be used. These bis-polydiacetylene-phenylene derivatives exhibit a color change from blue to red and red to blue reversibly according to temperature without a substituent that causes typical hydrogen bonds, and electrospun fibers containing them also exhibit a temperature of 20 to 120°C. It shows the characteristics of heat discoloration in the range. In addition, the bis-polydiacetylene-phenylene derivative may have a densely packed structure from π-π interactions between aryl groups and hydrophobic interactions between alkyl groups, and thus may exhibit excellent reversible thermochromic properties.

[Formula 1]

Here, m is an integer of 0 to 20, l is an integer of 0 to 30, and n is an integer of 1 or more.

In the case of using the compound represented by Formula 1, a mixed solution may be obtained by dissolving and stirring a monomer of a bis-polydiacetylene-phenylene derivative and poly(ethylene oxide) (PEO) in a solvent. Here, the monomer of the bis-polydiacetylene-phenylene derivative has a structure as shown in Formula 2 below having a polydiacetylene group on both sides of a p-phenylene group.

[Formula 2]

Here, m is an integer of 0 to 20, and l is an integer of 0 to 30.

When the component of the bis-polydiacetylene-phenylene derivative is included in the tile joint, excellent thermal discoloration characteristics can be exhibited in a relatively wide temperature range than the temperature range in which the thermal discoloration of polydiacetylene occurs.

On the other hand, since the tile joint construction area is narrowly spaced (1~3㎜), inorganic fine powder minerals with relatively fine particles 50.00~70.00 wt%, calcium carbonate 20.00~40.00 wt%, fibrous minerals for the purpose of preventing cracks such as fine cracks 1.00 to 8.00 wt%, pigment 2.00 to 5.00 wt%, thickener 0.05 to 1.00 wt%, dispersant 0.02 to 1.00 wt%, polyester silicone synthetic resin 15.00 to 30.00 wt%, inorganic antibacterial agent 1.00 to 7.00 wt%, polydiacetylene 5.00 It can be prepared by constituting the material in ~10.00% by weight.

5 is an exemplary view showing a tile joint construction state using a tile joint agent having a color change according to the temperature manufactured through the process of FIG. 4.

Referring to FIG. 5, before applying the tile joint agent having a color change according to the temperature produced through the process of FIG. 4 to the gap between the tile and the tile, foreign substances are removed, and the tile 100 and the tile ( 100) is applied to the gap between. The tile joint agent can be applied in an appropriate thickness in consideration of the drying time, and is usually applied in a thickness of 0.5 to 2 mm. After the tile joint agent is applied, the tile surface is cleaned by wiping the area around the tile 100 to which the tile joint agent is applied with a cleaning member such as a cloth. At this time, it is possible to shorten the curing time of the tile joint 200 using a curing machine.

According to an exemplary embodiment, the tile 100 on which the tile joint 200 is constructed using a tile joint agent having a color change according to temperature has an achromatic white color. In this state, when the surrounding temperature rises due to a fire in the building where the tile 100 is constructed, the color change tile joint 300 becomes due to the polydiacetylene component of the tile joint 200. For example, as shown in FIG. 5, a color change tile joint 300 in which white of the tile joint 200 is changed to red due to external temperature stimulation is formed. Accordingly, it is possible to quickly recognize and cope with the occurrence of a fire in the building, thereby minimizing damage to people and property.

Although the above has been described with reference to the preferred embodiments of the present application, those skilled in the art will variously modify the present invention within the scope not departing from the spirit and scope of the present invention described in the following claims. And it will be appreciated that it can be changed.
