Description

Eco-friendly non-flammable paint composition for coating heating equipment and manufacturing method thereof

The present invention relates to an eco-friendly non-combustible paint composition for coating a heating device and a method for manufacturing the same, and more particularly, it can completely block the spread of flame by forming a non-combustible coating film by coating and curing it on the inner surface of a case of a heating device. In addition, it relates to an eco-friendly nonflammable paint composition for coating a heating device having deodorization and absorption of volatile organic compounds and a method for manufacturing the same.

In general, a heating device is installed indoors to supply heat to an indoor space. Heating devices include radiant heaters that radiate radiant heat to indoor spaces. Radiant heaters are usually ceiling fans installed on the ceiling. The ceiling fan includes a case, a heating wire disposed inside the case, and a heat sink dissipating heat generated from the heating wire into the room.

A conventional ceiling fan has a paint applied to the inner surface of the case. However, the conventional paint is a general paint having a function of only a paint, and is not a functional paint having a flame retardancy. These anti-condensation paints used general paints and were manufactured by changing the types and contents of resins and additives, which are the main components of the paint, to give an anti-condensation effect. there is a problem.

In addition, the conventional ceiling fan has a problem in that the temperature rises due to continuous heat generation as power is continuously supplied due to an abnormality in a safety device such as a bimetal, thereby generating a flame.

Eco-friendly non-flammable paint composition for coating heating equipment

The eco-friendly non-combustible paint composition for coating a heating device according to an embodiment of the present invention can completely block the spread of a flame by forming a non-combustible coating film by applying and curing it to the inner surface of a case of a heating device, as well as a volatile organic compound of deodorization and absorption.

Accordingly, the non-combustible coating film formed on the inner surface of the case of the heating device continues to be supplied with power due to an abnormality in the safety device (bimetal, etc.) of the heating device. Even if a spark occurs due to an abnormality in the device due to the dust accumulated in it, it is possible to prevent the flame from spreading in advance.

In addition, the eco-friendly non-combustible paint composition for coating a heating device according to an embodiment of the present invention can promote antiseptic, sterilization and antibacterial effects by adding environmentally friendly rosin resin, and has excellent deodorization and absorption functions of volatile organic compounds do.

In addition, the eco-friendly non-flammable paint composition for coating a heating device according to an embodiment of the present invention has excellent adsorption power, so that it can be stably attached without falling off from the inner surface of the case of the heating device even when used for a long period of time.

In addition, the eco-friendly non-combustible paint composition for coating a heating device according to an embodiment of the present invention is a coating agent for manufacturing a non-combustible coating film by having excellent dispersibility in which each material is uniformly distributed without aggregation regardless of the upper layer and the lower layer. suitable for use

To this end, the eco-friendly nonflammable paint composition for coating a heating device according to an embodiment of the present invention contains 10 to 25 wt% of a water-soluble acrylic resin, 15 to 35 wt% of a water-soluble silicone resin, 20 to 40 wt% of a primer, and 10 to 30 wt% of a flame retardant , 0.1 to 3% by weight of silver powder, 1 to 10% by weight of rosin resin, 0.1 to 3% by weight of fragrance, 0.5 to 7% by weight of pigment, and 0.1 to 3% by weight of a fluidizing agent.

The water-soluble acrylic resin binds the components included in the eco-friendly non-combustible paint composition as a binder, and is added to adhere the eco-friendly non-combustible paint composition to the surface to be coated in the form of a coating film for installation of heating devices.

As the water-soluble acrylic resin, a high molecular weight acrylic resin having a weight average molecular weight of 50,000 to 100,000 g/mol is preferably used. As such, the high molecular weight acrylic resin has excellent transparency, and has improved scratch resistance, adsorption properties and impact strength, thereby contributing to improvement of the durability of the coating film.

The water-soluble acrylic resin is preferably added in a content ratio of 10 to 25% by weight of the total weight of the eco-friendly paint composition, and 15 to 20% by weight may be presented as a more preferable range. When the addition amount of the water-soluble acrylic resin is less than 10% by weight, there is a fear that crosslinking between components included in the eco-friendly paint composition is not good. Conversely, when the water-soluble acrylic resin exceeds 25% by weight, dispersibility and adsorption properties may be deteriorated.

The water-soluble silicone resin binds the components included in the eco-friendly non-combustible paint composition as a binder, and is added to adhere the eco-friendly non-combustible paint composition to the surface to be coated in the form of a coating film for installation of a heating device.

The water-soluble acrylic resin is preferably added in a content ratio of 15 to 35% by weight of the total weight of the eco-friendly paint composition, and 20 to 30% by weight may be presented as a more preferable range. When the addition amount of the water-soluble acrylic resin is less than 15% by weight, there is a fear that crosslinking between components included in the eco-friendly paint composition is not good. Conversely, when the water-soluble acrylic resin exceeds 35% by weight, dispersibility and adsorption properties may be deteriorated.

The primer has an insulating function and is added to improve the adsorption performance of the eco-friendly non-combustible paint composition. As such a primer, a mixture of a silicone resin and an acrylic resin may be used.

The primer is preferably added in a content ratio of 20 to 40% by weight of the total weight of the eco-friendly paint composition, and 25 to 35% by weight may be presented as a more preferable range. When the amount of primer added is less than 20% by weight, when coating with a non-combustible coating film, the coating property is remarkably deteriorated, and there is a fear that adsorption may not be performed well. Conversely, when the amount of primer added exceeds 40% by weight, it is not preferable because it may act as a factor to deteriorate the durability of the coating film.

A flame retardant is added to impart flame retardant performance. Such a flame retardant has excellent flame retardant effect, and it is preferable to use an environmentally friendly non-active halogen-based flame retardant that is not toxic to the human body. Such non-halogen-based flame retardants include melamine cyanurate (MCA), ammonium polyphosphate (APP), trihydroxyethyl isocyanurate (THEIC), triethyl phosphate (TEP), triphenyl phosphate (TPP) and tri It is preferable to use at least one selected from cresyl phosphate (TCP), and among them, it is most preferable to use melamine cyanurate (MCA).

The flame retardant is preferably added in a content ratio of 10 to 30% by weight of the total weight of the eco-friendly nonflammable paint composition, and 15 to 25% by weight may be presented as a more preferable range. When the amount of the flame retardant added is less than 10% by weight, it may be difficult to properly exhibit the flame retardant performance. Conversely, when the amount of the flame retardant is excessively added in excess of 30% by weight, there is a problem of lowering the adhesive force, which is not preferable.

Silver powder has antibacterial and sterilizing effects, and has an excellent deodorizing effect. It is preferable to use a spherical particle shape having an average diameter of 0.1 to 1 μm as the silver powder. When the average diameter of the spherical silver 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 eco-friendly non-flammable paint composition. Conversely, when the average diameter of the spherical silver powder exceeds 1 μm, it is difficult to achieve dispersion stabilization.

The silver powder is preferably added in a content ratio of 0.1 to 3% by weight of the total weight of the eco-friendly nonflammable coating composition, and 0.5 to 1.5% by weight may be presented as a more preferable range. When the amount of silver powder added is less than 0.1% by weight, it may be difficult to properly exhibit antibacterial, sterilizing and deodorizing effects. Conversely, when the amount of silver powder added exceeds 3% by weight, it is not preferable because it may interfere with the curing reaction of the polymer and act as a factor to decrease strength.

It is more preferable to add the first silver powder and the second silver powder having different diameters to the silver powder in a weight ratio of 3:1 to 5-1. In this case, the first silver powder may have an average diameter of 0.1 to 0.3 μm, and the second silver powder may have an average diameter of 0.6 to 1 μm.

The first silver powder having a small average diameter is preferably added in a content ratio greater than that of the second silver powder having a large average diameter. This is because the first silver powder has a larger surface area than the second silver powder, and thus the first silver powder having a small average diameter is added. The interfacial affinity between the water-soluble acrylic resin and the water-soluble silicone resin is excellent, so that dispersion stability can be further improved. As described above, as the content of the second silver powder increases, dispersion stability may deteriorate. Therefore, it is preferable that the second silver powder be added in an amount smaller than that of the first silver powder.

Resin resin is added in the eco-friendly non-combustible paint composition to absorb harmful substances and to keep the coated non-combustible coating film from being cracked for a long time. These rosin resins are made in powder form by dissolving solid rosin in boiling water to remove the toxicity of rosin and remove stickiness.

The rosin resin is preferably added in a content ratio of 1 to 10% by weight of the total weight of the eco-friendly non-combustible coating composition, and a content ratio of 3 to 7% by weight may be presented as a more preferable range. If the amount of rosin resin added is less than 1% by weight, the coated non-combustible coating may be cracked or the light may fade. Conversely, when the amount of rosin resin added exceeds 10% by weight, it is not preferable because it may act as a factor to decrease strength.

Fragrance is added to remove specific odors such as water-soluble acrylic resins, water-soluble silicone resins, and primers. These perfumes may be used without particular limitation as long as they can remove specific odors such as acrylic resins, water-soluble silicone resins, and primers. For example, a product of Givaudan Co., Ltd. may be used as the fragrance.

The fragrance is preferably added in a content ratio of 0.1 to 3% by weight of the total weight of the eco-friendly nonflammable paint composition. When the added amount of the fragrance is less than 0.1% by weight, there is a fear that a specific odor may not be completely removed. Conversely, when the amount of fragrance added exceeds 3% by weight, it is not economical because it may act as a factor increasing only the manufacturing cost due to excessive addition of fragrance without any further effect.

The pigment is added to the eco-friendly non-flammable paint composition, and serves to produce a white color. For this, a white pigment may be used as the pigment, but is not limited thereto. As an example, the pigment may be a white pigment manufactured by Mixol.

The pigment is preferably added in a content ratio of 0.5 to 7% by weight of the total weight of the eco-friendly nonflammable paint composition. When the amount of the pigment is added in a small amount less than 0.5% by weight, there is a fear that a white color may not be realized. Conversely, when the amount of the pigment added exceeds 7 wt %, it is not preferable because it may act as a factor to reduce the durability of the non-combustible coating film.

The fluidizing agent improves the flow characteristics of the non-combustible coating composition to maintain uniform spreadability, thereby increasing the flatness of the non-combustible coating film and improving workability for forming the non-combustible coating film. Such a fluidizing agent may include at least one selected from natural oil, turpentine oil, and orange oil.

The fluidizing agent is preferably added in a content ratio of 0.1 to 3% by weight of the total weight of the eco-friendly nonflammable paint composition. When the amount of the glidant added is less than 0.1% by weight, it is difficult to properly exhibit the effect of improving the fluidity, and there is a concern that the spreadability is not good. 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.

In addition, the eco-friendly nonflammable paint composition for coating a heating device according to an embodiment of the present invention may further contain 0.1 to 2 wt% of hydroquinolbis(2,6-dimethylphenyl)phosphate.

Hydroquinolbis(2,6-dimethylphenyl)phosphate increases adhesive strength without degrading dispersibility, thereby enhancing adsorption.

When the amount of hydroquinolbis (2,6-dimethylphenyl) phosphate added was less than 0.1 wt %, the effect of improving the adhesion was insignificant. Conversely, when the amount of hydroquinolbis(2,6-dimethylphenyl)phosphate added exceeds 2 wt%, it is not preferable because there is a risk of lowering the durability of the coating film.

Method of manufacturing eco-friendly non-combustible paint composition for coating heating equipment

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

As shown in Fig. 1, the method for manufacturing an eco-friendly non-combustible paint composition for coating a heating device according to an embodiment of the present invention includes a first mixing step (S110), a second mixing step (S120), a third mixing step (S130), It includes a fourth mixing step (S140) and a defoaming step (S150).

1st mixing

In the first mixing step (S110), the rosin resin, the silver powder, and the flame retardant are first mixed at a speed of 400 to 600 rpm to form a first mixing powder.

Here, the reason for adding the rosin resin is to maximize the antiseptic effect of the non-combustible paint composition and to promote the anti-fungal effect together with the silver powder.

This rosin resin has an antiseptic and antibacterial effect, as well as a strong bactericidal and antibacterial effect.

Figure 2 is a photograph showing the actual measurement by taking a rosin resin.

As shown in FIG. 2, rosin resin refers to a product prepared in powder form by dissolving rosin in boiling water to remove the toxicity of rosin, remove stickiness, and so on. It can be seen that these rosin resins exhibit a light yellow color.

To this end, rosin resin pulverizes solid rosin, melts the pulverized rosin in water at 110 to 130 ° C. for 30 to 90 minutes, and then puts it in water at 15 to 20 ° C. The process of re-pulverizing, and bathing the pulverized rosin with water at 110 to 130° C. for 30 to 90 minutes is repeated at least three times to remove impurities and toxicity. Accordingly, impurities are removed from the rosin resin, and the stickiness and toxicity of the rosin are significantly reduced.

In this step, the primary mixing is preferably carried out for 90 to 180 minutes at 25 ~ 35 ℃, which is the optimum temperature for mixing well and not sticking rosin resin without melting.

As such, in the first mixing, rosin resin is put in a low-speed mixer and mixed at a speed of 400 to 600 rpm until it reaches 25 to 35 ° C. It is preferred to run for minutes.

3 is a photograph showing the first mixing by taking a picture.

As shown in FIG. 3 , it can be seen that the primary mixing powder in which rosin resin, silver powder and flame retardant are mixed is uniformly mixed and shows a white color. At this time, when the rosin resin and silver powder are mixed with water, the silver powder sinks and the rosin resin melts and cannot be confirmed with the naked eye.

secondary mixing

In the secondary mixing step (S120), the water-soluble acrylic resin, the water-soluble silicone resin, the primer, and the fluidizing agent are secondarily mixed at a speed of 1,000 to 3,000 rpm to form a secondary mixing powder.

At the time of secondary mixing, it is preferable to perform dispersion using a homomixer at a speed of 1,000 to 3,000 rpm at 10 to 30° C. for 2 to 6 hours. As such, the secondary mixing should be performed at a low temperature of 10 to 30°C and at a high speed of 1,000 to 3,000 rpm, which is because the water-soluble acrylic resin, water-soluble silicone resin, primer and fluidizing agent do not mix well with each other. because there is

When mixing for less than 2 hours at a speed of less than 1,000 rpm in the secondary mixing, there is a risk of poor dispersibility due to severe aggregation between the water-soluble acrylic resin, the water-soluble silicone resin, the primer, and the fluidizing agent. Conversely, when mixing for more than 6 hours at a speed exceeding 3,000 rpm during secondary mixing, the water-soluble acrylic resin, the water-soluble silicone resin, the primer, and the fluidizing agent may be damaged, which is not preferable.

In this secondary mixing, it is more preferable to carry out the ultrasonic treatment together with the output power conditions of 15 to 20 kHz and 40 to 50 W. In this way, in the process of secondary mixing of the water-soluble acrylic resin, the water-soluble silicone resin, the primer, and the fluidizing agent at a speed of 1,000 to 3,000 rpm, when the ultrasonic treatment is performed together, the dispersion efficiency is maximized to prevent aggregation of each material. can be prevented in advance.

When the ultrasonic output power is less than 40W, there is a possibility that each component may not be uniformly dispersed. Conversely, when the ultrasonic output power exceeds 50W, each material may be damaged due to excessive time exposure to high output power, which is not preferable.

tertiary mixing

In the third mixing step (S130), the first mixing portion and the second mixing portion are thirdly mixed at a speed of 1,000 to 3,000 rpm to form a tertiary mixing portion.

In the third mixing, dispersion using a homomixer is preferably carried out at a speed of 1,000 to 3,000 rpm at 40 to 45° C. for 10 to 60 minutes. As such, the 3rd mixing must be performed at a high speed of 1,000 to 3,000 rpm in a state where the temperature is raised to 40 ~ 45 ℃, which is higher than the 2nd mixing, which is the mixing dispersion in the case of the 1st and 2nd mixing minutes. In order to control this tendency, the temperature is raised to increase the distribution of particles.

In this third mixing step (S130), although the powder and liquid are mixed at less than 40° C., it takes a long time and an undispersed lump may be seen with an approximate probability of 2/1,000. In addition, when the temperature exceeds 47°C, the load is weak at 3,000 rpm, which is the mixing control speed, and the temperature of 47°C or higher rapidly rises to 60°C, making it difficult to control the temperature. Therefore, if the temperature rises rapidly, there is a risk of fire and a change in viscosity (thinning), making it difficult to generate desired bubbles. Therefore, in the tertiary mixing, it is possible to have an appropriate viscosity while generating appropriate bubbles when a cooling facility is provided to control the temperature and mixing is performed while maintaining the temperature of 40 to 45°C.

4th mixing

In the fourth mixing step (S140), the fourth mixing powder is formed by fourth mixing the pigment and the fragrance in the tertiary mixing powder at a speed of 1,000 to 3,000 rpm.

In the fourth mixing, it is preferable to use a homomixer at a speed of 1,000 to 3,000 rpm at 40 to 45° C. for 10 to 60 minutes. As such, the fourth mixing is preferably performed at a high speed of 1,000 to 3,000 rpm in a state where the temperature is raised to 40 to 45° C. like the third mixing.

At the time of this fourth mixing, it is more preferable to perform the ultrasonic treatment together under the conditions of output power of 15 to 20 kHz and 40 to 50 W. In this way, in the process of fourth mixing of pigments and fragrances at a speed of 1,000 to 3,000 rpm in the third mixing, if ultrasonic treatment is performed together, the dispersion efficiency is maximized to prevent aggregation of each material in advance. be able to

When the ultrasonic output power is less than 40W, there is a possibility that each component may not be uniformly dispersed. Conversely, when the ultrasonic output power exceeds 50W, each material may be damaged due to excessive time exposure to high output power, which is not preferable.

defoaming

In the defoaming step (S150), the fourth mixing powder is defoamed to form an eco-friendly non-combustible paint composition.

In this step, defoaming is performed to remove air bubbles present in the fourth mixing minute. For this defoaming, it is preferable to perform low-speed mixing for 1 to 4 hours at a low speed of 200 to 400 rpm at 20 to 30°C.

After this defoaming step, the eco-friendly nonflammable paint composition contains 10 to 25% by weight of a water-soluble acrylic resin, 15 to 35% by weight of a water-soluble silicone resin, 20 to 40% by weight of a primer, 10 to 30% by weight of a flame retardant, 0.1 to 3% by weight of silver powder, It contains 1 to 10% by weight of rosin resin, 0.1 to 3% by weight of a fragrance, 0.5 to 7% by weight of a pigment, and 0.1 to 3% by weight of a fluidizing agent.

In addition, the eco-friendly nonflammable paint composition may further include 0.1 to 2 wt% of hydroquinolbis(2,6-dimethylphenyl)phosphate. Such hydroquinolbis(2,6-dimethylphenyl)phosphate is preferably added together with a water-soluble acrylic resin, a water-soluble silicone resin, a primer and a fluidizing agent during the second mixing step.

Through the above process, the method for manufacturing an eco-friendly non-combustible paint composition for coating a heating device according to an embodiment of the present invention may be completed.

As seen so far, the eco-friendly non-combustible paint composition for coating a heating device and a manufacturing method thereof according to an embodiment of the present invention are perfect for spreading the flame by coating and curing the inner surface of the case of the heating device to form a non-combustible coating film. In addition to being able to block it, it has deodorization and absorption of volatile organic compounds.

Accordingly, the non-combustible coating film formed on the inner surface of the case of the heating device continues to be supplied with power due to an abnormality in the safety device (bimetal, etc.) of the heating device. Even if a spark occurs due to an abnormality in the device due to the dust accumulated in it, it is possible to prevent the flame from spreading in advance.
