Non-combustible paint composition for coating ceiling fan

The non-combustible paint composition for coating a ceiling fan having excellent deodorization, antibacterial properties, anti-condensation properties and adhesive strength according to an embodiment of the present invention forms a non-combustible coating film by applying and curing it on the inner surface of the case of the ceiling fan.

Accordingly, the non-combustible coating film formed on the inner surface of the case of the ceiling-type heater may generate a flame due to continuous heat generation as power continues to be supplied due to an abnormality in the safety device (bimetal, etc.) of the ceiling-type heater, or Even if a spark occurs due to an abnormal spark due to dust accumulated inside the hot air fan, it is possible to prevent the flame from spreading in advance.

In addition, the nonflammable paint composition according to the embodiment of the present invention has excellent deodorization and absorption functions of volatile organic compounds (VOCs), and has a dehydration function to control humidity, so it can prevent dew condensation, and has excellent antibacterial properties has

In addition, the non-combustible paint composition according to the embodiment of the present invention has excellent high-temperature adhesion, so that it is stably attached without falling off from the inner surface of the case of the ceiling fan even when used for a long period of time.

To this end, the non-combustible paint composition for coating a ceiling fan having excellent deodorization, antibacterial properties, anti-condensation properties and adhesion according to an embodiment of the present invention contains 20 to 40% by weight of porous ceramic powder, 10 to 20% by weight of hollow filler, and a fluidizing agent. 0.1 to 3% by weight, aluminum thickener 0.1 to 1% by weight, nathrazole 0.1 to 1% by weight, antifoaming agent 0.5 to 3% by weight, dextrin 1 to 5% by weight, preservative 0.1 to 2% by weight, epichlorohydrin-modified phenolform 10 to 30% by weight of aldehyde resin, 3 to 5% by weight of glass fiber, and the remainder of the modified silane silicate.

The modified silane silicate is used as a binder as a main component of a non-flammable paint composition. This modified silane silicate serves to strengthen the adhesion to the case of the metal ceiling fan by forming a covalent bond through the double organic-inorganic reactivity.

The modified silane silicate is added in a content ratio of 20 to 60% by weight based on the total weight of the nonflammable coating composition, and as a more preferable range, 30 to 40% by weight may be presented. When the modified silane silicate is added in an amount of less than 20% by weight, it may be difficult to secure adhesion to the case of the ceiling fan. Conversely, when the amount of the modified silane silicate exceeds 60% by weight, it may be difficult to secure mechanical strength due to the large amount of the modified silane silicate is added.

Porous ceramic powder improves deodorization by inhibiting the growth of volatile organic compounds (VOCs) or mold, and also serves to reinforce the strength of non-combustible coatings.

The porous ceramic powder is added in a content ratio of 20 to 40% by weight based on the total weight of the non-combustible coating composition, and 25 to 35% by weight may be presented as a more preferable range. When the porous ceramic powder is added in an amount of less than 20% by weight, it may be difficult to properly exhibit the effect of improving deodorization and strength. Conversely, when the porous ceramic powder is added in a large amount in excess of 40 wt%, it may interfere with the curing reaction of the polymer and act as a factor to decrease strength.

The porous ceramic powder includes at least one selected from zeolite, alumina, zirconia and silica. In this case, it is more preferable to use the porous ceramic powder in the form of particles or fibers having an average diameter of 0.1 to 1 μm. When the average diameter of the porous ceramic powder is less than 0.1 μm, it is not preferable because there is a risk of being directly exposed to the surface of the non-combustible coating composition. Conversely, when the average diameter of the ceramic powder exceeds 1 μm, it is difficult to achieve dispersion stabilization.

Here, it is more preferable to use a porous ceramic powder coated with a silane coupling agent. The silane coupling agent improves the dispersibility by improving the interfacial affinity between the porous ceramic powder and the modified silane silicate. As a silane coupling agent, aminoethylaminopropyltriethoxysilane, bis[(3-triethoxysilyl)propyl]amine, N-(triethoxysilylmethyl)aniline, triethoxysilylmethyl)diethylamine, 1 At least one selected from -[3-(triethoxysilyl)propyl]urea and the like may be used.

In addition, as for the porous ceramic powder, it is more preferable to add the first porous ceramic powder and the second porous ceramic powder having different diameters in a weight ratio of 2: 1 to 4 to 1. In this case, the first porous ceramic powder may have an average diameter of 0.1 to 0.4 μm, and the second porous ceramic powder may have an average diameter of 0.5 to 1 μm.

As such, it is preferable to add the first porous ceramic powder having a relatively small average particle diameter in a content ratio greater than that of the second porous ceramic powder having a large average particle diameter, which means that the first porous ceramic powder has a surface area larger than that of the second porous ceramic powder. Since it is large, the interfacial affinity between the first porous ceramic powder having a small average diameter and the modified silane silicate is excellent, so that dispersion stability can be further improved. As such, as the content of the second porous ceramic powder increases, dispersion stability may deteriorate. Therefore, the second porous ceramic powder should be added in an amount smaller than that of the first porous ceramic powder.

Hollow fillers are added to improve thermal insulation and fire resistance. The hollow filler includes at least one selected from a fly ash hollow body, a ceramic hollow body, a Shirasu balloon, a silica balloon, an elvan stone balloon, and a mineral balloon.

These hollow fillers are added in a content ratio of 10 to 20% by weight based on the total weight of the nonflammable paint composition, and 14 to 18% by weight may be presented as a more preferable range.

When the added amount of the hollow filler is less than 10% by weight, it may be difficult to secure thermal insulation and fire resistance performance. Conversely, when the amount of the hollow filler exceeds 20% by weight, it is not preferable because it may act as a factor impairing strength due to the addition of a large amount of the hollow filler having a hollow structure.

The fluidizing agent improves the flow characteristics of the non-combustible coating composition to increase the flatness of the formed non-combustible coating film, and serves to improve workability for forming the non-combustible coating film.

Such a fluidizing agent is added in a content ratio of 0.1 to 3% by weight of the total weight of the nonflammable coating composition, and as a more preferable range, 1 to 2% by weight may be presented. When the amount of the fluidizing agent added is less than 0.1% by weight, it is difficult to properly exhibit the effect of improving the fluidity. Conversely, when the amount of the fluidizing agent added exceeds 3% by weight, it is not preferable because it may act as a factor to decrease strength.

Aluminum thickener and natrasol play a big role in the formation and stability of granules of a certain size by maintaining the viscosity, and by using various thickeners in addition, it is possible to reduce costs while applying the advantages of each component. Each of these aluminum thickeners and nathrazole is added in a content ratio of 0.1 to 1% by weight of the total weight of the non-combustible coating composition, and 0.3 to 0.6% by weight may be presented as a more preferable range.

The antifoaming agent is added for the purpose of removing air bubbles or suppressing the generation of air bubbles during the manufacturing process of the non-combustible coating composition or the process of forming the non-combustible coating film by spray coating.

The antifoaming agent is added in a content ratio of 0.5 to 3% by weight of the total weight of the nonflammable paint composition, and 1.5 to 2.0% by weight may be presented as a more preferable range. When the amount of the antifoaming agent added is less than 0.5% by weight, the effect of removing bubbles or inhibiting the formation of bubbles is insignificant, so that a crater phenomenon appears in the non-combustible coating film or surface defects may occur by weakening the strength of the non-combustible coating film, which is not preferable. Conversely, when the amount of the antifoaming agent added exceeds 3% by weight, it is not preferable because it is present as an impurity due to the large amount added and may act as a factor to decrease strength.

Dextrin serves to improve the scratch resistance and scratch recovery properties of the non-combustible coating film.

Such dextrin is added in a content ratio of 1 to 5% by weight based on the total weight of the nonflammable coating composition, and as a more preferable range, 2 to 3% by weight may be presented. When the amount of dextrin added is less than 1% by weight, it is difficult to properly exhibit the effect of improving elasticity, flexibility, and scratch resistance of the non-combustible coating film. Conversely, when the amount of dextrin is excessively added exceeding 5% by weight, there is a risk of lowering the hardness of the non-combustible coating film.

The preservative serves to prevent the non-combustible coating composition from decaying or the collapse of the non-combustible coating film.

These preservatives are added in a content ratio of 0.1 to 2% by weight based on the total weight of the nonflammable coating composition, and 0.5 to 1.0% by weight may be presented as a more preferable range. When the amount of the preservative added is less than 0.1% by weight, the decay rate is fast and the shelf life of the non-combustible paint composition may be shortened. Conversely, when the amount of the preservative to be added exceeds 2% by weight, it may cause a decrease in adhesive strength.

Epichlorohydrin-modified phenolformaldehyde resin serves to enhance the strength as well as to strengthen the adhesion with the modified silane silicate.

The epichlorohydrin-modified phenolformaldehyde resin is added in a content ratio of 10 to 30% by weight based on the total weight of the nonflammable coating composition, and 15 to 20% by weight may be presented as a more preferable range. When the addition amount of the epichlorohydrin-modified phenol formaldehyde resin is less than 10% by weight, it is difficult to properly exhibit the effect of improving adhesion and strength. Conversely, when the amount of the epichlorohydrin-modified phenolformaldehyde resin added exceeds 30% by weight, it may be difficult to secure mechanical strength due to the excessive addition of the epichlorohydrin-modified phenolformaldehyde resin.

Glass fibers are processed into fibers by melting and processing glass containing silicate as a main component, and serves to improve mechanical strength. Such a glass fiber can be manufactured by rapidly cooling and solidifying the glass in a molten state as it is by sharply pulling it through a nozzle with an extremely fine diameter so as not to instantaneously crystallize it.

At this time, it is preferable to use a glass fiber having an average diameter of 1 to 5 μm and an average length of 0.5 to 1 mm. can be obtained In addition, when the average length of the glass fiber is in the range of 0.5 to 1 mm, it is easy to put it into a processing device such as an extruder, and the impact reinforcing effect can be greatly improved.

Glass fiber can be used in the shape of a circle, an oval, a rectangle, or a dumbbell in which two circles are connected. In this case, as the glass fiber, a cross-section aspect ratio of less than 1.5 may be used, and specifically, a circular-shaped glass fiber having a cross-sectional aspect ratio of 1 may be used. In this case, the aspect ratio is defined as the ratio of the longest diameter to the smallest diameter in the cross section of the glass fiber. When glass fiber with a cross-section aspect ratio is used, the unit price of the product can be lowered in terms of price, and dimensional stability and appearance can be improved by using glass fiber with a circular cross-section.

Glass fiber is added in a content ratio of 3 to 5% by weight based on the total weight of the non-combustible coating composition, and 3.5 to 4.5% by weight may be presented as a more preferable range. When the amount of glass fiber added is less than 3% by weight, the effect of improving the mechanical strength is insignificant and it is difficult to expect the effect of improving the impact resistance. Conversely, when the amount of glass fiber added exceeds 5% by weight, transparency is deteriorated due to the large amount of glass fiber added, and there is a problem of impairing workability.

In addition, the non-flammable paint composition for coating a ceiling fan having excellent deodorization, antibacterial, anti-condensation and adhesion according to an embodiment of the present invention contains 2,2-bis(3,5-dimethyl-4-hydroxyphenyl)propane. may include more.

2,2-bis(3,5-dimethyl-4-hydroxyphenyl)propane enhances adhesion without reducing the strength of the non-flammable coating. When 2,2-bis(3,5-dimethyl-4-hydroxyphenyl)propane is further added to the non-combustible paint composition of the present invention, there is a gap between the case of the ceiling fan and the non-combustible coating film attached to the inner surface of the ceiling fan. It was confirmed through an experiment that the adhesive strength was greatly improved.

2,2-bis(3,5-dimethyl-4-hydroxyphenyl)propane is added in a content ratio of 0.5 to 3% by weight based on the total weight of the nonflammable paint composition, and a more preferred range is 1.0 to 2.0% by weight. can When the amount of 2,2-bis(3,5-dimethyl-4-hydroxyphenyl)propane added was less than 0.5 wt%, the effect of improving the adhesion was insignificant. Conversely, when the amount of 2,2-bis(3,5-dimethyl-4-hydroxyphenyl)propane is excessively added exceeding 3% by weight, there is a risk of lowering mechanical strength, which is not preferable.

Method of manufacturing non-combustible paint composition for coating ceiling fan

1 is a process flow chart showing a method for manufacturing a non-combustible paint composition for coating a ceiling fan according to an embodiment of the present invention.

As shown in FIG. 1, the method for manufacturing a non-combustible paint composition for coating a ceiling fan according to an embodiment of the present invention includes a modified silane silicate forming step (S110), a first mixing step (S120), and a second mixing step (S130). ) is included.

modified Silanesilicate formation

In the modified silane silicate forming step (S110), the alkoxysilane is hydrolyzed by acid treatment to form a hydrolyzable silane compound, potassium silicate and a solvent are mixed with the hydrolyzable silane compound, and then at 80 to 100° C. for 1 to 2 hours. react to form a modified silanesilicate.

In this step, the hydrolyzable silane compound is maintained at a reaction temperature of 80 to 100 ° C., 5 to 10 parts by weight of a strong acid and 20 to 30 parts by weight of water are added dropwise to 100 parts by weight of alkoxysilane at a rate of 15 to 30 ml/min. It can be prepared by stirring at a speed of 300 to 500 rpm for 1 to 3 hours. In this case, for the acid treatment, one or more acidic solutions selected from sulfuric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid, and the like may be used.

primary mix

In the first mixing step (S120), porous ceramic powder, a hollow filler, a fluidizing agent and an aluminum thickener are added to the modified silane silicate, and the first mixing is performed by ultrasonication while stirring at a speed of 500 to 1,000 rpm.

In this step, the ultrasonic treatment of the primary mixing is preferably performed for 1 to 3 hours under the conditions of 15 to 20 kHz and 30 to 50 W of output power. If the ultrasonic output power is less than 30 W or the ultrasonic treatment time is less than 1 hour, there is a fear that the modified silane silicate, porous ceramic powder, hollow filler, fluidizing agent and aluminum thickener may not be uniformly mixed in the solvent. Conversely, if the ultrasonic output power exceeds 50W or the ultrasonic treatment time exceeds 3 hours, it may act as a factor to increase the manufacturing cost and time without further increasing the effect, so it is not economical.

secondary mixing

In the second mixing step (S130), nathrazole, an antifoaming agent, dextrin, preservative, epichlorohydrin-modified phenol formaldehyde resin and glass fiber are added to the first mixed mixture, and while stirring at a speed of 1,500 to 2,500 rpm, ultrasonic waves Secondary mixing by treatment to form a non-flammable paint composition.

In this step, it is preferable to process the ultrasonic treatment of the secondary mixing within a short time under high output power condition than the ultrasonic treatment of the primary mixing, which is to maximize the dispersibility by performing the secondary mixing within a short time under the high output power condition to be.

To this end, the ultrasonic treatment of the secondary mixing is preferably performed for 5 to 20 minutes under the conditions of 30 to 40 kHz and 210 to 230 W of output power. As such, in the process of adding and stirring nathrazole, an antifoaming agent, dextrin, preservative, epichlorohydrin-modified phenolformaldehyde resin and glass fiber to the first mixed mixture, secondary high-power ultrasonication is performed. When bubble collapse occurs after elapse of time, the temperature of 5000 K, the pressure of about 1000 bar, and the heating and cooling rate of 10 ¹⁰ K/s have extreme conditions, so that the dispersion efficiency is improved. can be maximized.

In this case, when the ultrasonic output power is less than 210W or the ultrasonic treatment time is less than 5 minutes, there is a risk that the components may not be uniformly dispersed despite supplying high output power. Conversely, when the ultrasonic output power exceeds 230W or the ultrasonic treatment time exceeds 20 minutes, the components in the mixture may be damaged due to excessive time exposure to high output power, which is not preferable.

In this step, the non-flammable paint composition contains 20 to 40 wt% of porous ceramic powder, 10 to 20 wt% of hollow filler, 0.1 to 3 wt% of a fluidizer, 0.1 to 1 wt% of an aluminum thickener, 0.1 to 1 wt% of nathrazole, 0.5 wt% of an antifoaming agent ~ 3% by weight, dextrin 1 ~ 5% by weight, preservative 0.1 ~ 2% by weight, epichlorohydrin-modified phenolformaldehyde resin 10 ~ 30% by weight, glass fiber 3 ~ 5% by weight, and the rest of the modified silane silicate 40 ~ 70 It may have a composition and a composition ratio including weight %. In addition, in this step, it is more preferable to further add 0.5 to 3% by weight of 2,2-bis(3,5-dimethyl-4-hydroxyphenyl)propane to the first mixed mixture.

By the above process, the method for manufacturing a non-combustible paint composition for coating a ceiling fan having excellent deodorizing properties, antibacterial properties, anti-condensation properties, and adhesive strength according to an embodiment of the present invention can be completed.

As described so far, the non-combustible paint composition according to the present invention forms a non-combustible coating film by applying and curing it to the inner surface of the case of the ceiling fan.

Accordingly, the non-combustible coating film formed on the inner surface of the case of the ceiling-type heater may generate a flame due to continuous heat generation as power continues to be supplied due to an abnormality in the safety device (bimetal, etc.) of the ceiling-type heater, or Even if a spark occurs due to an abnormal spark due to dust accumulated inside the hot air fan, it is possible to prevent the flame from spreading in advance.

In addition, the nonflammable paint composition according to the present invention has excellent deodorization and absorption functions of volatile organic compounds (VOCs), and has a dehydration function to control humidity, thereby preventing dew condensation and has excellent antibacterial properties.
