Description

Lacquer composition for initial suppression

The present invention relates to a lacquer composition for initial suppression.

Conventional fire extinguishing consisted of a fire extinguishing method that directly extinguishes fire using a fire extinguisher, but a fire extinguishing system was developed due to the advancement of technology. It is widely used. Briefly explaining the mechanism of the fire extinguishing system, the gas fire extinguishing system is mainly physical fire extinguishing by reducing the oxygen concentration of the fire source, and the powder fire extinguishing system suppresses physical and chemical properties by contacting the powder sprayed with the flame by the action of pressurized gas. It is extinguished through action, and the water-based fire extinguishing system suppresses fire through three actions: cooling of water fog, suffocation, and blocking heat radiation.

In the case of fires in collective facilities such as apartments, underground passages and subway fires, it is difficult to extinguish fires by the fire extinguishing system directly due to the generation of toxic substances and gases. Accordingly, in order to prevent the spread of fire, flame retardant materials or paints are used in the above facilities to passively block the spread of fire.

In relation to the Republic of Korea Patent Laid-Open No. 10-2011-0051395 discloses a foamed refractory paint. Specifically, it is disclosed that by including oil-based and water-based resins, flame retardants, non-combustible inorganic compounds, reinforcing agents, foaming agents and expanded graphite, it has high thermal insulation properties and can prevent the fire-resistant paint layer from falling off due to wind pressure after foaming. It only has a function of delaying time, but there is a limit in that it cannot exhibit a fire extinguishing function to extinguish an initial fire. Therefore, the existing fire extinguishing system and a system with a fire extinguishing function for early fire suppression and a fire fighting function capable of preventing fire were required.

Therefore, in Korean Patent Laid-Open No. 10-2018-0043570, a paint composition having a firefighting function and a sheet having a firefighting function using the same were developed, but according to this, a polyurethane resin, MMA, and a fire extinguishing agent are included, so that the surface of various materials It may cause problems with adhesion to use. Accordingly, there is a problem in that an epoxy primer must be pre-coated prior to application of the polyurethane-type paint, and when a fire extinguishing agent is directly injected, a problem occurs in long-term storage of the paint.

Therefore, in the present invention, unlike the passive fire preparation method that withstands high temperatures without being burned by the use of refractory materials, flame retardants, and flame retardant paints, the paint containing the capsule-type extinguishing agent containing the extinguishing material is applied to the expected fire area. In the process of burning the paint by heat generated in the event of a fire by painting on it, the fire can be actively prevented by extinguishing the fire initially by the fire extinguishing agent inside the paint tissue, while increasing the adhesion of the substrate and enhancing long-term storage. It is a technical solution to provide a lacquer composition for suppressing initial fire using a fire extinguishing agent.

In order to solve the above technical problem, the present invention,

15 to 45 parts by weight of enamel resin including modified alkyd resin and nitrocellulose resin, 20 to 45 parts by weight of solvent, 15 to 50 parts by weight of capsule type fire extinguishing agent, 3 to 25 parts by weight of colored pigment, 15 to 35 parts by weight of extender pigment Consisting of including 0.1 to 10 parts by weight of parts and additives, the capsule-type fire extinguishing agent is formed in a core-shell structure, the core contains a fluorinated ketone-based fire extinguishing agent, and the shell is cross-linked It provides a lacquer composition for initial suppression using a capsule-type fire extinguishing agent, characterized in that it is formed of a polymer.

Preferably, the nitrocellulose resin is included in an amount of 1 to 20 parts by weight based on 100 parts by weight of the lacquer composition, and the solid content ratio is 50 to 80% based on the total weight of the lacquer composition.

Preferably, the solvent is 30 to 40 parts by weight of toluene, 10 to 22 parts by weight of xylene, 20 to 30 parts by weight of 2-methylisobutyl ketone, 5 to 10 parts by weight of isopropyl alcohol, and 5 to 10 parts by weight of dimethyl carbonate It characterized in that it includes.

Preferably, the capsule-type fire extinguishing agent is characterized in that the particle size is 50 ~ 150㎛.

The lacquer composition for extinguishing the initial fire using the capsule-type fire extinguishing agent according to the present invention is contained in the coating film during painting as the capsule-type fire extinguishing agent is used, and the capsule reacts by heat of 90 to 230° C. at the beginning of the fire to extinguish the fire. It has the effect of extinguishing the fire in the early stage by spraying the drug. In addition, as the digestive agent is included in the form of a capsule, there is an effect of increasing the storage capacity.

In addition, the coating composition according to the present invention has an effect that can be applied to various material surfaces by improving adhesion to the material surface by including the enamel resin.

In addition, the present invention is a room temperature drying lacquer paint based on an enamel resin containing a nitrocellulose resin and a modified alkyd resin to form a strong and strong coating film, and has an effect of forming a coating film excellent in color, gloss, hardness, and durability.

1 is a photograph showing a result of an initial re-suppression experiment according to an embodiment of the present invention.

Hereinafter, the present invention will be described in detail.

The lacquer composition of the present invention includes 15 to 45 parts by weight of an enamel resin including a modified alkyd resin and a nitrocellulose resin, 20 to 45 parts by weight of a solvent, 15 to 50 parts by weight of a capsule type fire extinguishing agent, and 3 to 25 parts by weight of a colored pigment, 15 to 35 parts by weight of an extender pigment and 0.1 to 10 parts by weight of an additive are included. The lacquer composition of the present invention is applied to the surface of objects such as buildings, furniture, and electric wires to form a coating film, thereby imparting functions such as antifouling, rust prevention, flame resistance, and waterproofness to the surface of the object, and aesthetics due to gloss and color, It is characterized in that it can be used for initial recompression by a fire extinguishing agent.

In this case, the modified alkyd resin may be obtained by using an alkyd resin, which is a polymer material formed by a condensation reaction of a polyhydric alcohol and a polyhydric acid, as a base, and modifying it with fats or oils or fatty acids.

Polyhydric acid, a raw material of alkyd resin, is an acid containing two or more hydrogen atoms capable of neutralizing a base in one molecule. For example, phthalic anhydride, tetrahydrophthalic anhydride, hexahydro phthalic anhydride, itaconic anhydride, 3 One or more polyhydric acids selected from the group consisting of -methyl-tetrahydrophthalic anhydride, 4-methyl-hexahydrophthalic anhydride, trimellitic anhydride, succinic anhydride and maleic anhydride may be used.

Polyhydric alcohol, another raw material of alkyd resin, is an alcohol having two or more hydroxy groups in one molecule, for example, ethylene glycol, diethylene glycol, polyethylene glycol, propylene glycol, dipropylene glycol, 1,3-butylene One or more polyhydric alcohols may be used to select from the group consisting of glycol, isopentyldiol, pentylene glycol, 1,2-hexanediol, hexylene glycol, pentaerythritol, glycerin and trimethylolpropane.

On the other hand, as fats and oils or fatty acids that induce denaturation of alkyd resins, for example, suberine fatty acid, cutin fatty acid, soybean fatty acid, rice bran oil fatty acid, rapeseed fatty acid, sunflower oil fatty acid, safflower oil fatty acid, drinking oil fatty acid, cottonseed fatty acid, Tall oil fatty acid, olive oil fatty acid, castor oil fatty acid, dehydrated castor oil fatty acid, linseed oil fatty acid, walnut oil fatty acid, coconut oil fatty acid, linseed oil fatty acid, linoleic acid and oleic acid, and the like may be used.

In this way, since the modified alkyd resin can be formed by a combination of various raw materials, the physical properties of the resin can be variously changed by controlling the type and amount of these raw materials. Can be used in combination with.

In the present invention, the modified alkyd resin may include soybean fatty acid, rice bran oil fatty acid, dehydrated castor oil fatty acid or coconut oil fatty acid; Phthalic anhydride; And at least one or more polyhydric alcohols selected from the group consisting of pentaerythritol, glycerin, and trimethylolpropane. In more detail, the modified alkyd resin may be prepared by reaction of 60 to 80 parts by weight of phthalic anhydride and 20 to 40 parts by weight of glycerin based on 100 parts by weight of coconut oil fatty acid.

Next, the nitrocellulose resin contained in the enamel resin quickly dries the lacquer composition, has an appropriate non-volatile content, so that a coating film having a sufficient thickness is formed even with a small number of times, and has the advantage of having a high solid content.

In relation to the nitrocellulose resin, it is preferable to use a resin having a solid content of 50 to 70%, which in the case of a lacquer composition requires several coatings in order to have an appropriate hiding power, in order to increase the solid content of the paint. Therefore, when the solid content of the nitrocellulose resin is less than 50%, it is difficult to manufacture a paint with a high solid content, and when the solid content exceeds 70%, the amount of non-volatile content is high, so the amount of organic solvent used increases in order to manufacture lacquer of an appropriate viscosity. This is because VOCs (Volatile Organic Compounds) increase.

On the other hand, it is preferable that the nitrocellulose resin contains 1 to 20 parts by weight based on 100 parts by weight of the enamel resin, which is less than 1 part by weight, so that the resin does not function properly due to the small content, and in the case of 20 parts by weight or more This is because the solid content of lacquer may be lowered because an excessive amount of organic solvent is required to dissolve the high molecular weight nitrocellulose.

On the other hand, it is preferable to contain 20 to 45 parts by weight of the solvent, because if the solvent is less than 20 parts by weight, the viscosity of the lacquer composition is high and workability deteriorates, and if it exceeds 45 parts by weight, the flowability decreases due to low viscosity. No, it is because the solid content is low, so several paintings are required.

In relation to the solvent, 30 to 40 parts by weight of toluene, 10 to 22 parts by weight of xylene, 20 to 30 parts by weight of 2-methylisobutyl ketone, 5 to 10 parts by weight of isopropyl alcohol, and 5 to 10 parts by weight of dimethyl carbonate. It is desirable.

In connection with this, the solvent will be additionally described.

First, in the case of toluene and xylene, it is possible to exhibit excellent compatibility with other solvents while diluting the enamel resin having a high solid content as it is included in the lacquer composition as an aromatic hydrocarbon solvent.

2-Methylisobutyl ketone is a ketone type solvent called MIBK (METHYL ISOBUTYL KETONE) and preferably contains 20 to 30 parts by weight in order to dissolve the high molecular weight nitrocellulose resin. If it is contained in less than 20 parts by weight, it is difficult to dissolve the nitrocellulose resin, so the viscosity of the lacquer composition is high. If it is contained in an amount exceeding 30 parts by weight, it is difficult to form a coating film because the low viscosity and flow properties of the paint are poor. In addition, due to the use of excessive ketones, a large amount of dust is generated during airless operation, making it difficult to form a smooth coating film.

Isopropyl alcohol is a non-polar solvent with high solubility, so it is preferable to contain 5 to 10 parts by weight to help pigment dispersion.If it is less than 5 parts by weight, the pigment may not be evenly dispersed, and the amount exceeds 10 parts by weight. This is because it affects the drying properties during the formation of the coating film.

Next, dimethyl carbonate solves the storage stability and low-temperature stability problems of the lacquer composition, and has the advantage of having a low risk of fire due to a high flash point of the solvent. In addition, not only does not cause irritating odor, it is excellent in solubility and volatility, and it is preferable to include 5 to 10 parts by weight to help improve workability due to a short drying time. If it is contained in an amount of less than 5 parts by weight, the modified alkyd resin cannot be sufficiently diluted, and since a relatively large amount of other solvents are included, the solid content is lowered, and drying properties may also be affected. On the other hand, if it is contained in excess of 10 parts by weight, it not only causes unevenness and cloudiness due to rapid volatilization in the initial drying stage of the lacquer paint, but also does not properly exhibit the function of the dried coating film. In addition, due to the high freezing point, there is a problem that when working in a low temperature environment such as in winter, it is not volatilized, but it is rather frozen, making it difficult to work, and there is a problem that the physical properties of the coating film formed at low temperature are rapidly deteriorated. In addition, dimethyl carbonate easily evaporates in a room temperature or high temperature environment, resulting in poor storage stability, and process reliability can be reduced because the ratio of the modified alkyd resin and solvent is easily changed.

In addition, in the present invention, the capsule-type extinguishing agent includes a cross-linked epoxy resin in the form of a shell, and the capsule-type extinguishing agent includes a fluorinated ketone-based extinguishing agent. In relation to this, the capsule-type extinguishing agent has the principle that the epoxy resin shell is destroyed by the temperature crossing of about 120°C due to the occurrence of fire, and the nano-sized extinguishing agent inside the capsule-type extinguishing agent is exposed to the outside, thereby inducing extinguishing. . In addition, the capsule-type fire extinguishing agent was developed to have a particle size of 50 to 150 μm, and as it has such a reduced size of micro-units, it can be effectively applied to a paint for initial repressive with a smooth coating film. More preferably, in order to be used as a top coat due to the nature of the lacquer composition, it is preferable to include a capsule-type fire extinguishing agent having a particle size of 50 to 70 μm.

In addition, preferably, the capsule type fire extinguishing agent 15 to 50 parts by weight should be included. This is because if the capsule-type fire extinguishing agent is less than 15 parts by weight, it does not sufficiently exhibit the digestive function, and if it exceeds 50 parts by weight, not only the storage capacity decreases, but also the viscosity increases, and in severe cases, the paint gelling occurs. Because it does.

In addition, in the present invention, as the colored pigment, non-organic pigments such as titanium oxide, iron oxide, iron hydroxide, and chromium oxide may all be used, and when the colored pigment is included in less than 3 parts by weight, the hiding power decreases, thereby providing a function as a paint. It is not exerted, and when the amount exceeds 25 parts by weight, the oil absorption of the pigment is high, so the viscosity is high, so it is preferable to use 3 to 25 parts by weight in order to realize sufficient color and workability. It is desirable to adjust the ratio with the solvent in consideration.

As a specific example of the pigment applicable to the present invention, titanium dioxide is suitable as the white pigment, and R-902 (manufacturer: DUPONT) is representative. In addition, CINQUASIA MAGENTA RT-343 (manufacturer: CIBA) with quinacridone component for red pigments, PALIOTOL YELLOW L-2140HD (manufacturer: BASF) with isoindolinone component for yellow/orange pigments, and blue pigments Cooper-phthaloxyamine series IRGAZIN BLUE X-3367 (manufacturer: CIBA) is applicable, but this is only listed as a preferred revelation, and the types of colored pigments that can be used are not limited thereto.

In addition, in the present invention, the extender pigment is preferably included in an amount of 15 to 35 parts by weight so that a sufficient thickness of the coating film can be formed when the coating film is formed by mixing with the resin. These extender pigments include Illite-Mica, titanium dioxide, zeolite, silica sand, elvanite, ocherite, olivine, kaolin, silicate mineral, diatomaceous earth, wollastonite, pyrophyllite, dolomite, lithium mineral, magnesite, bauxite. , Bentonite, sepiolite, iron oxide, graphite, talc, clay minerals, titanium minerals, tourmaline, fly ash, and blast furnace slag.

In addition, in the present invention, the additive is preferably included in accordance with the characteristics of the pigment and the use of the paint, and generally includes a plasticizer, a dispersant, an antifoaming agent, a leveling agent, and an adhesion promoter. In relation to the additive, it is preferable to include 0.1 to 10 parts by weight. In this case, if the amount of additive is less than 0.1 parts by weight, the effect of the additive cannot be properly exerted.For example, in the case of an antifoaming agent, air bubbles in the paint may remain, causing a pinhole phenomenon when used, and in the case of a dispersant, the Anyo particles are evenly dispersed. As a result, the surface of the coating film is not smooth. In addition, when the additive ratio exceeds 10 parts by weight, problems such as color separation, bird nacelle, and poor drying may occur, and when the ratio of the plasticizer among the additives is high, there is a problem that the strength decreases when forming a coating film.

As a specific example of the additive applicable to the present invention, as a plasticizer, for example, NEO-T (Aekyung Petrochemical) or ECO-DEHCH (Hanwha Chemical), as a defoaming agent, for example, Depol CFC-165A (Cheongwoo FC) or BYK-065 (BYK) may be used, but these are only listed as desirable revelations, and the types of plasticizers or defoaming agents that can be used are not limited thereto.

In addition, in the present invention, the solid content ratio of the lacquer composition is preferably 50 to 80% based on the total weight of the lacquer composition. This is because it is possible to form a sufficient coating film through minimal coating.

Hereinafter, the present invention will be described in more detail through examples, but the present invention is not limited thereto.
