Description
본 발명은 금속 등의 표면 도장에 사용되는 세라믹 코팅제에 관한 것으로, 더욱 상세하게는 경화시간 지연과 발열온도 도달시간의 지연이 가능하고 더불어 도포 피막의 부착성능 및 내부식성 향상, 도포 피막의 기공발생 억제 등 우수한 품질 확보가 가능한 새로운 세라믹 코팅제에 관한 것이다.The present invention relates to a ceramic coating used for painting the surface of metals, etc., and more specifically, to delay the curing time and delay the time to reach the heating temperature, as well as improve the adhesion performance and corrosion resistance of the applied film, and prevent the occurrence of pores in the applied film. It is about a new ceramic coating that can secure excellent quality, including suppression.
철제 등 금속 재료에는 금속 표면을 코팅제로 도장 처리하며, 대표적인 코팅제로는 에폭시계, 비닐에스테르계, 폴리우레탄 등의 유기계 도료가 있다. 그러나 유기계 도료는 금속 표면과의 접착성은 우수하나 변형특성이 금속과 큰 차이를 나타내어 장기적으로 금속 표면에서 탈락이 일어나는 문제점이 있고, 또한 도료의 도포작업이 상도, 중도, 하도의 3단계로 실시하기 때문에 전체 시공난이도의 상승과 더불어 작업시간이 많이 소요되는 단점이 있다. 이러한 문제를 해결하고자 금속 표면에 도금 처리를 하여 부식을 최소화하는 방법이 제안되어 사용되기도 한다. 하지만 도금 처리방법은 육안상 부식 진행 판별이 어렵고, 도금 표면이 부식된 이후 곧바로 도금 내부 금속의 부식이 진행되기 때문에 효과적인 부식방지 성능을 기대하기 어렵다.For metal materials such as iron, the metal surface is painted with a coating agent, and representative coating agents include organic paints such as epoxy, vinyl ester, and polyurethane. However, organic paints have excellent adhesion to metal surfaces, but their deformation characteristics are very different from metals, so there is a problem of falling off from the metal surface in the long term. Additionally, the paint application process is carried out in three stages: top coat, middle coat, and bottom coat. Therefore, it has the disadvantage of increasing overall construction difficulty and requiring a lot of work time. To solve this problem, a method of minimizing corrosion by plating the metal surface has been proposed and used. However, with the plating treatment method, it is difficult to visually determine the progress of corrosion, and since corrosion of the metal inside the plating proceeds immediately after the plating surface is corroded, it is difficult to expect effective anti-corrosion performance.
한편, 금속 표면을 도장하기 위한 도료로 유기계 도료 외에 무기계 도료도 있으며, 대표적인 무기계 도료에는 MgO계 인산 세라믹 코팅제가 있다. MgO계 인산 세라믹 코팅제는 마그네시아와 인산염계 경화제가 반응하여 경화하는 코팅제인데, 기존의 유기계 도료들과는 달리 금속 표면과의 직접적인 이온결합을 통해 도포 기재면에 부착되어 코팅 도막을 형성하게 된다. 이러한 MgO계 인산 세라믹 코팅제는 접착성 및 내구성이 우수하고 부식방지 성능 또한 효과적이며, 속경성의 재료로 하도 단일 시공이 가능하여 공사기간, 공사비 절감이 가능하는 이점이 있다.Meanwhile, paints for painting metal surfaces include inorganic paints in addition to organic paints, and a representative inorganic paint is MgO-based phosphoric acid ceramic coating agent. MgO-based phosphoric acid ceramic coating is a coating that hardens by reacting magnesia with a phosphate-based hardener. Unlike existing organic paints, it attaches to the surface of the applied substrate through direct ionic bonding with the metal surface to form a coating film. These MgO-based phosphoric acid ceramic coatings have excellent adhesion and durability, and are also effective in preventing corrosion. They are fast-hardening materials and can be applied in a single coat, which has the advantage of reducing construction time and costs.
그런데 기존 MgO계 인산 세라믹 코팅제는 다음과 같은 여러 가지 단점이 지적되었다. 첫째 경화시간이 짧아 빠른 시공이 가능한 숙련된 작업자가 필요하다. 둘째 혼합 도포 후에 급격하게 발열되면서 도포면의 경화가 진행되는데, 경화 중 발생되는 가스가 도포면의 피막경화로 배출되면서 기공을 발생시켜 도포면의 불량을 초래한다. 셋째, 경화시간이 짧기 때문에 도포 기재면과의 반응이 충분하지 않아 도포피막의 부착성능이 저하한다.However, the existing MgO-based phosphoric acid ceramic coatings had several disadvantages, including: First, the curing time is short, so skilled workers are needed for quick construction. Second, after mixing and application, hardening of the applied surface progresses as heat is rapidly generated, and the gas generated during curing is discharged as the film hardens on the applied surface, creating pores and causing defects in the applied surface. Third, because the curing time is short, the reaction with the surface of the coated substrate is not sufficient, which reduces the adhesion performance of the coated film.
본 발명은 종래 금속 표면 도장용 코팅제의 단점을 개선하고자 개발된 것으로서, 혼합 후 충분한 경화시간 확보, 발열온도 도달시간 지연이 가능한 새로운 세라믹 코팅제를 제공하는데 기술적 과제가 있다.The present invention was developed to improve the shortcomings of conventional coating agents for painting metal surfaces, and has a technical challenge in providing a new ceramic coating agent that can secure sufficient curing time after mixing and delay the time to reach the heating temperature.
더불어 본 발명은 도포 피막의 부착성능 및 내부식성 향상, 도포 피막의 기공발생 억제 등 우수한 품질 확보가 가능한 세라믹 코팅제를 제공하고자 한다.In addition, the present invention seeks to provide a ceramic coating agent that can secure excellent quality, such as improving the adhesion performance and corrosion resistance of the applied film and suppressing pores in the applied film.
상기한 기술적 과제를 해결하기 위해 본 발명은, 마그네시아(MgO) 20~55중량%, 규회석 20~60중량%, 황산나트륨 5~10중량%, 물 10~20중량%를 포함하는 A액; 일인산암모늄 20~30중량%, 일인산칼륨 15~30중량%, 인산알루미늄 화합물 1~7중량%, 붕산 0.1~2.5중량%, 탄산칼륨 2.5~3.5중량%, 물 30~55중량%를 포함하는 B액;으로 구성되어, A액과 B액이 부피비로 1:1로 혼합되는 것을 특징으로 하는 경화 지연형 세라믹 코팅제를 제공한다. 여기서 인산알루미늄 화합물은, 80~90중량% 농도의 인산수용액 100중량부에 수산화알루미늄 30~35중량부가 혼합된 것으로, 항온수조에서 11~15℃로 유지되게 하면서 인산수용액을 투입하여 교반 유지하고 수산화알루미늄을 투입하여 혼합 교반 유지한 후 여과 건조하여 분말상태로 제조된 것을 바람직하게 적용할 수 있다.In order to solve the above-described technical problem, the present invention provides a solution A containing 20 to 55% by weight of magnesia (MgO), 20 to 60% by weight of wollastonite, 5 to 10% by weight of sodium sulfate, and 10 to 20% by weight of water; Contains 20 to 30% by weight of ammonium monophosphate, 15 to 30% by weight of potassium monophosphate, 1 to 7% by weight of aluminum phosphate compound, 0.1 to 2.5% by weight of boric acid, 2.5 to 3.5% by weight of potassium carbonate, and 30 to 55% by weight of water. It provides a delayed-curing ceramic coating agent, which consists of liquid B, wherein liquid A and liquid B are mixed in a 1:1 volume ratio. Here, the aluminum phosphate compound is a mixture of 30 to 35 parts by weight of aluminum hydroxide in 100 parts by weight of an aqueous phosphoric acid solution with a concentration of 80 to 90% by weight. The aqueous phosphoric acid solution is maintained at 11 to 15°C in a constant temperature water bath, stirred and maintained, and then hydrated. A product prepared in powder form by adding aluminum, maintaining mixing, and then filtering and drying can be preferably used.
본 발명에 따르면 다음과 같은 효과를 기대할 수 있다.According to the present invention, the following effects can be expected.
첫째, 반응억제제(붕산, 인산알루미늄 화합물)의 적용으로 인산염의 급격한 반응을 억제함으로써 경화시간 지연을 통한 작업시간 확보가 가능하며, 이로써 시공작업 용이성 확보 가능해진다. 더불어 경화시간 확보를 통해 도포기재면과 충분한 반응이 이루어지게 됨으로서, 도포피막의 부착성능을 향상시키고 내부식성을 향상시킬 수 있다.First, by suppressing the rapid reaction of phosphate by applying a reaction inhibitor (boric acid, aluminum phosphate compound), it is possible to secure work time by delaying the curing time, thereby ensuring ease of construction work. In addition, by securing the curing time, sufficient reaction occurs with the surface of the coated substrate, thereby improving the adhesion performance of the coated film and improving corrosion resistance.
둘째, 염기성 혼화제(Na2SO4)의 적용으로 반응분위기의 pH를 올림으로써 지속적인 반응을 통한 완만한 반응열 발생 유도가 가능하며, 이로써 도포면의 경화 지연으로 경화중 발생 가스의 배출이 용이해져 도포면의 기공 발생을 저감시킬 수 있다. Second, by raising the pH of the reaction atmosphere by applying a basic admixture (Na 2 SO 4 ), it is possible to induce a gradual generation of reaction heat through continuous reaction. This delays the curing of the coated surface and facilitates the discharge of gases generated during curing, thereby increasing the temperature of the coated surface. It can reduce the occurrence of pores.
본 발명은 경화 지연형 세라믹 코팅제에 관한 것으로, 마그네슘 성분과 인산염과의 급격한 반응을 억제하여 경화를 지연하기 위해 붕산, Na2SO4, 인산알루미늄 화합물을 사용한다는데 특징이 있다.The present invention relates to a curing delay type ceramic coating agent, and is characterized by using boric acid, Na 2 SO 4 , and aluminum phosphate compounds to delay curing by suppressing rapid reaction between magnesium components and phosphate.
구체적으로 본 발명에 따른 경화 지연형 세라믹 코팅제는, 마그네시아(MgO) 20~55중량%, 규회석 20~60중량%, 황산나트륨 5~10중량%, 물 10~20중량%를 포함하는 A액;과, 일인산암모늄 20~30중량%, 일인산칼륨 15~30중량%, 인산알루미늄 화합물 1~7중량%, 붕산 0.1~2.5중량%, 탄산칼륨 2.5~3.5중량%, 물 30~55중량%를 포함하는 B액;으로 구성되는 것을 특징으로 하며, 여기서 A액과 B액은 부피비로 1:1로 혼합된다.Specifically, the curing delayed ceramic coating according to the present invention is Liquid A containing 20 to 55% by weight of magnesia (MgO), 20 to 60% by weight of wollastonite, 5 to 10% by weight of sodium sulfate, and 10 to 20% by weight of water; , 20 to 30% by weight of ammonium monophosphate, 15 to 30% by weight of potassium monophosphate, 1 to 7% by weight of aluminum phosphate compound, 0.1 to 2.5% by weight of boric acid, 2.5 to 3.5% by weight of potassium carbonate, and 30 to 55% by weight of water. It is characterized in that it consists of liquid B containing; where liquid A and liquid B are mixed in a volume ratio of 1:1.
A액에서 마그네시아(MgO)는 세라믹 생성을 위한 주요한 재료가 된다. 일반적인 마그네시아보다는 과소 마그네시아가 바람직한데, 일반적인 마그네시아는 빠른 반응속도로 인해 작업시간 확보에 어려움이 있기 때문에 반응성이 낮은 과소된 마그네시아가 바람직한 것이다. 마그네시아는 반응성, 경제성 및 물리적 특성을 감안하여 20~55중량% 포함되는 것이 바람직하다. 20중량% 미만이면 세라믹 형성을 위한 충분한 반응성 확보가 어렵고 또한 고강도의 세라믹 형성에 불리한 단점이 있으며, 55중량% 초과하면 경제성이 떨어지는 단점이 있다.In Liquid A, magnesia (MgO) becomes the main material for creating ceramics. Dehydrated magnesia is preferable to general magnesia. Because general magnesia has a fast reaction speed, it is difficult to secure working time, so dehydrated magnesia, which has low reactivity, is preferable. It is preferable that magnesia is included at 20 to 55% by weight, taking into account reactivity, economic efficiency and physical properties. If it is less than 20% by weight, it is difficult to secure sufficient reactivity for ceramic formation and there is a disadvantage in forming high-strength ceramics, and if it exceeds 55% by weight, there is a disadvantage that economic feasibility is poor.
A액에서 규회석은 무기계 필러로서 충전재가 되어 강도 성능을 증진시키고 코팅제의 균열방지에 기여한다. 특히 분말도가 1,800~3,000㎠/g인 섬유상으로 평균길이:직경의 비가 12:1 이상인 규회석이 더욱 바람직하다. 분말도가 1,800㎠/g 미만이면 충전이 치밀화되지 못하고, 3,000㎠/g 초과하면 섬유상 침상구조가 파괴되어 강도, 내구성 개선 및 균열 방지의 효과가 저하된다. 또한 섬유상 평균길이:직경의 비가 최소 12:1이상이 되어야 균열방지에 효과적으로 기여할 수 있다. 규회석은 20~60중량% 사용하는 것이 바람직한데, 20중량% 미만이면 필러로서의 혼입량이 작아 건조 시에 층분리되면서 도막불량이 발생하기 쉽고, 60중량% 초과하면 과도한 필러 혼입으로 인해 도막경화특성이 불량해진다.In solution A, wollastonite becomes an inorganic filler that improves strength performance and contributes to preventing cracking of the coating. In particular, wollastonite with a fineness of 1,800 to 3,000 cm2/g and an average length:diameter ratio of 12:1 or more is more preferable. If the powder size is less than 1,800 cm2/g, the filling cannot be densified, and if it exceeds 3,000 cm2/g, the fibrous needle structure is destroyed, reducing the effectiveness of improving strength and durability and preventing cracking. In addition, the average fiber length:diameter ratio must be at least 12:1 to effectively contribute to crack prevention. It is desirable to use 20 to 60% by weight of wollastonite. If it is less than 20% by weight, the amount mixed as a filler is small, so it is easy to cause film defects due to layer separation during drying. If it exceeds 60% by weight, the film hardening characteristics are poor due to excessive filler mixing. It becomes bad.
A액에서 황산나트륨(Na2SO4)은 염기성 혼화제로서 반응분위기의 pH를 올림으로써 지속적인 반응을 통해 완만한 반응열 발생을 유도한다. 완만한 반응열 발생으로 발열온도 도달시간의 지연이 가능해지고 이로 인해 도포면의 경화가 지연되며, 이로써 경화 중에 발생하는 가스의 배출이 용이해지면서 도포면의 기공발생을 억제할 수 있게 된다. 황산나트륨은 5~10중량%가 바람직한데, 5중량% 미만이면 염기성 분위기로의 pH 증가효과 영향이 부족하고, 10중량% 초과하면 과도한 pH 증가영향으로 오히려 급격한 경화문제가 발생한다.In solution A, sodium sulfate (Na 2 SO 4 ) is a basic admixture that increases the pH of the reaction atmosphere and induces a gradual generation of reaction heat through continuous reaction. Due to the gradual generation of reaction heat, it is possible to delay the time to reach the heating temperature, which delays curing of the coated surface. This makes it easier to discharge gases generated during curing and suppresses the generation of pores on the coated surface. Sodium sulfate is preferably 5 to 10% by weight. If it is less than 5% by weight, the effect of increasing pH in a basic atmosphere is insufficient, and if it exceeds 10% by weight, problems with rapid curing occur due to the excessive increase in pH.
A액에서 물은 혼합용매가 되는데, 10~20중량% 사용한다. 10중량% 미만이면 혼합 교반이 어려워지고, 20중량% 초과하면 혼입수 과량으로 인해 도막 경화특성이 불량해질 수 있다.In solution A, water becomes a mixed solvent and is used at 10 to 20% by weight. If it is less than 10% by weight, mixing and stirring becomes difficult, and if it exceeds 20% by weight, the coating film curing characteristics may be poor due to excessive amount of mixed water.
B액에서 일인산암모늄과 일인산칼륨은 인산염으로, 마그네시아와 반응하여 경화하는 주요한 재료가 된다. 일인산암모늄은 경화반응시 발열은 낮으나 암모니아 가스가 발생하여 도포면의 기공발생을 초래할 수 있으므로, 이러한 특성을 감안할 때 20~30중량%가 바람직하다. 일인산칼륨은 마그네시아의 반응을 감안하면 15~30중량%가 바람직하다. In solution B, ammonium monophosphate and potassium monophosphate are phosphates, which react with magnesia and become the main hardening materials. Ammonium monophosphate generates low heat during the curing reaction, but ammonia gas is generated and may cause pores on the coated surface. Considering these characteristics, 20 to 30% by weight is preferable. Considering the reaction of magnesia, the amount of monopotassium phosphate is preferably 15 to 30% by weight.
B액에서 인산알루미늄 화합물은 인산염의 급격한 반응을 억제하여 완만한 반응속도에 기여하는 재료가 된다. 인산알루미늄 화합물은 80~90중량% 농도의 인산수용액 100중량부에 수산화알루미늄 30~35중량부가 혼합된 것을 바람직하게 적용할 수 있다. 특히 이러한 인산알루미늄 화합물은 항온수조에서 11~15℃로 유지되게 하면서, 인산수용액을 투입하여 교반 유지하고 수산화알루미늄을 투입하여 혼합 교반 유지한 후 여과 건조하여 분말상태로 바람직하게 제조할 수 있다. 이렇게 제조된 인산알루미늄 화합물은 도포면 경화시간 증가를 통해 도포 기재면과 코팅제 간의 결합 향상에 기여한다. B액에서 인산알루미늄 화합물은 1~7중량% 사용하는 것이 바람직한데, 1중량% 미만이면 작업성 확보를 위한 경화 지연효과가 낮고, 7중량% 초과하면 과도한 경화 지연으로 코팅면의 불량이 발생할 우려가 있다.In solution B, the aluminum phosphate compound becomes a material that suppresses the rapid reaction of phosphate and contributes to a slow reaction rate. The aluminum phosphate compound can be preferably applied by mixing 30 to 35 parts by weight of aluminum hydroxide with 100 parts by weight of an aqueous phosphoric acid solution with a concentration of 80 to 90% by weight. In particular, this aluminum phosphate compound can be preferably manufactured in powder form by adding an aqueous phosphoric acid solution and maintaining stirring while maintaining the temperature at 11 to 15°C in a constant temperature water bath, maintaining mixing and stirring by adding aluminum hydroxide, and then filtering and drying. The aluminum phosphate compound prepared in this way contributes to improving the bond between the applied substrate surface and the coating agent by increasing the curing time of the applied surface. It is desirable to use 1 to 7% by weight of the aluminum phosphate compound in solution B. If it is less than 1% by weight, the curing delay effect to ensure workability is low, and if it exceeds 7% by weight, there is a risk of defects in the coating surface due to excessive curing delay. There is.
B액에서 붕산은 인산염의 급격한 반응을 억제하는 반응억제제로서 역할되며, 0.1~2.5중량%가 바람직하다. 0.1중량% 미만이면 인산염의 반응 억제효과가 부족하고, 2.5중량% 초과하면 도포 초기의 발열특성을 저하시켜 도포면의 경화전 흐름현상에 의한 불량이 발생할 우려가 있다.In solution B, boric acid acts as a reaction inhibitor to suppress the rapid reaction of phosphate, and is preferably 0.1 to 2.5% by weight. If it is less than 0.1% by weight, the effect of inhibiting the reaction of phosphate is insufficient, and if it exceeds 2.5% by weight, the heating characteristics at the beginning of application are lowered, and there is a risk of defects due to flow phenomenon before curing on the coated surface.
탄산칼륨은 인산염의 중화를 통한 반응성 저하에 기여하는 재료가 되며, 2.5~3.5중량%가 바람직하다. 2.5중량% 미만이면 인산염의 부분 중화영향이 낮아 인산염과 마그네시아의 반응성 저하 효과가 미미하고, 3.5중량% 초과하면 오히려 인산염의 과도한 중화영향으로 인해 경화특성이 부족할 우려가 있다.Potassium carbonate is a material that contributes to lowering reactivity through neutralization of phosphate, and is preferably 2.5 to 3.5% by weight. If it is less than 2.5% by weight, the partial neutralizing effect of phosphate is low, so the effect of lowering the reactivity of phosphate and magnesia is minimal. If it exceeds 3.5% by weight, there is a risk of insufficient curing properties due to the excessive neutralizing effect of phosphate.
B액에서 물은 혼합용매가 되는데, 30~55중량% 사용한다. 30중량% 미만이면 혼합 교반이 어려워지고, 55중량% 초과하면 혼입수 과량으로 인해 도막 경화특성이 불량해질 수 있다.In solution B, water becomes a mixed solvent and is used in an amount of 30 to 55% by weight. If it is less than 30% by weight, mixing and stirring becomes difficult, and if it is more than 55% by weight, the coating film curing characteristics may be poor due to excessive amount of mixed water.

2. 코팅제 특성 평가2. Evaluation of coating material properties
위의 [표 1]과 같은 조성으로 준비한 A액과 B액을 부피비로 1:1로 혼합한 코팅제에 대하여, 경화시간, 발열온도 도달시간, 도막 부착성능, 내부식성, 경화면 기공 여부에 대한 특성을 평가하였다. 경화시간은 코팅제의 점도가 5,000cPs 도달까지의 경과시간으로 측정하고, 발열온도 도달시간은 코팅제의코팅제 혼합용액 100ml의 60℃ 도달 소요시간(코팅제의 충분한 경화가 가능한 온도 60℃ 도달 시점까지의 경과시간으로 측정함. 1mm 이하의 코팅제 두께로 도포 시 발열온도에 대한 변별력이 없어 발열온도 변화확인을 위해 혼합코팅제 용액 100ml에 대해 측정함)을 측정하였다. 도막 부착성능은 부착성 실험(ASTM D 4541)을 실시하여 평가하였다. 내부식성은 철재부재에 코팅제 도포 후 3일 경과시점에서 코팅제 면에 철부재면에 외부에 노출되도록 스크래치를 낸 후 5% 염화나트륨 용액에 침지 유지하여 침지 경과일(15일, 30일, 60일)별 스크래치부위의 부식 발생여부로 측정하였으며, 경화면 기공 여부는 코팅면의 마감특성 확인을 위해 평가하였다. 평가결과는 아래 [표 2]와 같이 나타냈다.Regarding the coating agent prepared by mixing solution A and solution B in a 1:1 volume ratio as shown in [Table 1] above, the curing time, time to reach heating temperature, film adhesion performance, corrosion resistance, and cured surface porosity were evaluated. The characteristics were evaluated. The curing time is measured as the time elapsed until the viscosity of the coating agent reaches 5,000 cPs, and the time to reach the exothermic temperature is the time required for 100 ml of the coating agent mixture solution to reach 60℃ (elapsed time until the temperature reaches 60℃, at which sufficient curing of the coating agent is possible). (Measured by time. There was no discrimination in heating temperature when applied with a coating thickness of 1 mm or less, so 100 ml of mixed coating solution was measured to confirm the change in heating temperature). The coating film adhesion performance was evaluated by conducting an adhesion test (ASTM D 4541). Corrosion resistance is determined 3 days after applying the coating to the steel member, by scratching the surface of the coating to expose it to the outside, then immersing it in a 5% sodium chloride solution and maintaining it by immersion elapsed days (15 days, 30 days, 60 days). It was measured by whether corrosion occurred at the scratch area, and the presence or absence of porosity on the hardened surface was evaluated to confirm the finishing characteristics of the coated surface. The evaluation results are shown in [Table 2] below.
위와 같이 본 발명에 따라 황산나트륨(Na2SO4), 붕산, 인산알루미늄 화합물, 탄산칼륨(K2CO3)을 적절하게 혼입할 때 경화시간 지연, 발열온도 도달시간 지연, 부착성능 향상, 내부식성 향상, 코팅면의 마감 특성(기공여부) 향상이 확인된다. 특히 황산나트륨의 혼입으로 경화시간 지연, 발열 도달시간 지연 등 전반적인 성능 향상이 확인되며(비교예1과 실시예1,2), 붕산의 혼입으로 경화시간이 단축되나 코팅면의 마감 특성 개선이 학인되며(비교예3과 비교예6), 인산알루미늄 화합물의 혼입으로 경화시간 지연, 발열 도달시간 지연 등 전반적인 성능 향상이 확인되며(비교예2와 실시예1,2 또는 비교예3과 비교예5), 탄산칼륨의 혼입으로 부착강도 향상이 확인된다(비교예3과 실시예1,2). 이로써 본 발명에 따른 코팅제는 유리하게 활용할 수 있을 것이다. As described above, when sodium sulfate (Na 2 SO 4 ), boric acid, aluminum phosphate compound, and potassium carbonate (K 2 CO 3 ) are appropriately mixed according to the present invention, curing time is delayed, heating temperature is reached, improved adhesion performance, and corrosion resistance. Improvement, improvement in the finishing characteristics (porosity) of the coated surface is confirmed. In particular, overall performance improvement, such as delay in curing time and delay in heat generation time, is confirmed by the incorporation of sodium sulfate (Comparative Example 1 and Examples 1 and 2). Although the curing time is shortened by the incorporation of boric acid, it is recognized that the finishing characteristics of the coated surface are improved. (Comparative Example 3 and Comparative Example 6), overall performance improvement, such as delayed curing time and delayed heat generation time, was confirmed by the incorporation of the aluminum phosphate compound (Comparative Example 2 and Examples 1 and 2, or Comparative Example 3 and Comparative Example 5). , the adhesion strength was confirmed to be improved by the incorporation of potassium carbonate (Comparative Example 3 and Examples 1 and 2). As a result, the coating agent according to the present invention can be advantageously utilized.
