이하, 본 발명의 바람직한 실시예를 보다 상세하게 설명한다. 다만, 아래의 실시예는 이 기술분야에서 통상의 지식을 가진 자에게 본 발명이 충분히 이해될 수 있도록 설명된 것으로서 여러 가지 다른 형태로 변형될 수 있으며, 본 발명의 범위가 아래의 실시예에 한정되는 것은 아니다.Hereinafter, preferred embodiments of the present invention will be described in detail. It should be understood, however, that the invention is not limited to the embodiments described below, but may be modified in many ways without departing from the spirit and scope of the invention. It is not.
본 발명에 따른 수성 세라믹 불연도료 조성물의 제조방법은, 규산칼륨 용액에 1,2-사이클로헥산디올을 첨가하고 40~60℃에서 10~30분 동안 교반하여 60~70 중량%의 무기질 용액을 제조하는 단계와, 상기 용액에 중량 0.5~2%의 붕산을 첨가하여 180~220℃에서 1~3시간 동안 반응시키는 단계와, 상기 용액에 중량 5~10%의 물을 첨가하여 수성화하는 단계와, 상기 용액에 티탄산칼륨 5~15 중량%, 지르코늄 분말 3~12 중량%, 금속산화물로 이루어지는 안료 10~15 중량%, 분산제 0.5~5중량%을 첨가하여 혼합액을 교반하는 단계를 포함한다. The method for producing an aqueous ceramic flame retardant coating composition according to the present invention is characterized in that 1,2-cyclohexanediol is added to a potassium silicate solution and stirred at 40 to 60 DEG C for 10 to 30 minutes to prepare 60 to 70 wt% Adding 0.5 to 2% by weight of boric acid to the solution and reacting the solution at 180 to 220 ° C for 1 to 3 hours; adding water to the solution to 5 to 10% by weight to make it water-soluble; Adding 5 to 15 wt% of potassium titanate, 3 to 12 wt% of zirconium powder, 10 to 15 wt% of a pigment made of a metal oxide, and 0.5 to 5 wt% of a dispersant to the solution, and stirring the mixture.
본 발명에 따른 규산칼륨 용액은 후술하는 1,2-사이클로헥산디올과의 중축합반응에 의해 도막을 형성하는데, 형성되는 도막은 부착력과 내열성이 우수하고, 화재시 잘 타지않아 매연 등의 유독가스를 발생하지 않는다. 규산칼륨 용액은 일반적인 규산나트륨과 같이 탄산염을 형성하지 않으므로 모재의 표면에 백화현상이 발생하지 않고 후술하는 지르코늄 분말과의 혼화성이 높은 장점이 있다. The potassium silicate solution according to the present invention forms a coating film by a polycondensation reaction with 1,2-cyclohexanediol to be described later. The formed coating film is excellent in adhesion and heat resistance and does not burn well in a fire, . Since the potassium silicate solution does not form a carbonate like common sodium silicate, the whitening phenomenon does not occur on the surface of the base material and the compatibility with the zirconium powder described later is high.
본 발명에 따르면, 규산칼륨 용액은 산화칼륨 12~15중량%, 이산화규소 15~25 중량%, 인산 2~5 중량% 및 물 60~70중량%으로 배합되는 것이 바람직한데, 이를 통해 후술되는 지르코늄 분말의 첨가에 따라 접착성의 감소되는 것을 개선되어 모재의 표면에 도막이 내구성있게 형성할 수 있다. 그리고, 수용액에서의 안정화를 위해 규산칼륨의 SiO2/K2O 몰비가 1.3~3.5인 것이 바람직하다. According to the present invention, the potassium silicate solution is preferably blended with 12-15 wt% of potassium oxide, 15-25 wt% of silicon dioxide, 2-5 wt% of phosphoric acid and 60-70 wt% of water, It is possible to improve the adhesiveness by reducing the addition of the powder, so that the coating film can be durably formed on the surface of the base material. For the stabilization in an aqueous solution, the SiO 2 / K 2 O molar ratio of potassium silicate is preferably 1.3 to 3.5.
규산칼륨 용액에 1,2-사이클로헥산디올이 첨가되어 40~60℃에서 10~30분 동안 교반되어 무기질 용액이 제조된다. 1,2-사이클로헥산디올은 시클로헥산에서 두개의 수소를 수산기(OH-)로 치환된 구조로, 1,2-사이클로헥산디올의 하나의 수산기는 규산칼륨에 존재하는 하나의 수산기(OH-)와 탈수반응되고, 1,2-사이클로헥산디올의 다른 하나의 수산기는 규산칼륨에 존재하는 다른 수산기와 결합되어 중축합된다. 1,2-cyclohexanediol is added to the potassium silicate solution and stirred at 40 to 60 DEG C for 10 to 30 minutes to prepare a mineral solution. The 1,2-cyclohexanediol is a structure in which two hydrogens in cyclohexane are substituted with hydroxyl groups (OH - ), one hydroxyl group in 1,2-cyclohexanediol is a hydroxyl group (OH - ) present in potassium silicate, And the other hydroxyl group of 1,2-cyclohexanediol is combined with another hydroxyl group present in potassium silicate and polycondensed.
규산칼륨 용액에 1,2-사이클로헥산디올이 첨가되어 제조되는 무기질 용액은 전체 조성물 중량을 기준으로 60~70 중량%으로 형성된다. 무기질 용액이 60중량% 미만이면 도막의 내구성이 저하되고, 70중량% 초과되어 첨가될 경우 도막의 건조가 느려지는 문제점이 있다. 또한, 규산칼륨 용액과 1,2-사이클로헥산디올은 1:0.2 ~ 0.4의 중량비로 혼합되는 것이 바람직한데, 1,2-사이클로헥산디올이 0.2 미만으로 첨가되면 중축합반응이 원활하게 않게 되고, 0.4를 초과하여 첨가되더라도 반응속도가 개선되지 않는다. An inorganic solution prepared by adding 1,2-cyclohexanediol to a potassium silicate solution is formed in an amount of 60 to 70% by weight based on the total composition weight. If the amount of the inorganic solution is less than 60% by weight, the durability of the coating film is lowered, and if it is more than 70% by weight, drying of the coating film is slowed down. In addition, the potassium silicate solution and 1,2-cyclohexanediol are preferably mixed in a weight ratio of 1: 0.2 to 0.4. When 1,2-cyclohexanediol is added at less than 0.2, the polycondensation reaction is not smooth, If it is added in excess of 0.4, the reaction rate is not improved.
1,2-사이클로헥산디올과 규산칼륨의 탈수반응의 촉매로서 붕산이 첨가된다. 붕산의 첨가로 인해 도막의 내구성 및 내스크래치성이 보다 향상되어 외부 충격에도 도막이 쉽게 부스러지지 않게 된다. 본 발명에 따르면 붕산은 0.5~2 중량%가 첨가되는 것이 바람직한데, 2 중량%를 초과하여 첨가하면 반응액의 겔화가 발생하는 문제가 있고, 0.5 중량% 미만이 첨가되면 촉매로서 기능하지 못하는 문제가 있다. 신속한 반응을 위해 붕산을 첨가하여 비교적 고온인 180~220℃에서 1~3시간 동안 반응시키는 것이 바람직하다. Boric acid is added as a catalyst for the dehydration reaction of 1,2-cyclohexanediol with potassium silicate. The addition of boric acid improves the durability and scratch resistance of the coating film and prevents the coating film from being easily broken even in an external impact. According to the present invention, boric acid is preferably added in an amount of from 0.5 to 2% by weight. When the amount of boric acid is more than 2% by weight, gelation of the reaction solution occurs. If less than 0.5% by weight is added, . It is preferable to add boric acid for a rapid reaction and react at a relatively high temperature of 180 to 220 ° C for 1 to 3 hours.
본 발명에 따르면 중축합 반응 후에 물 5~10 중량%를 첨가하여 수성화시키는데, 첨가된 물은 도포된 모재로부터 증발되면서 건조 도막이 형성된다. 물은 수성 도료 제조시 통상적으로 이루어지고 있는 것이므로, 이에 대해서는 상세한 설명을 생략한다. According to the present invention, after the polycondensation reaction, 5 to 10% by weight of water is added to make it water-soluble. The added water evaporates from the coated base material to form a dried film. Since water is conventionally produced in the production of water-based paints, a detailed description thereof will be omitted.
그리고, 수성화된 용액에 티탄산칼륨, 지르코늄 분말, 안료, 및 분산제가 혼합된다. 티탄산칼륨은 무기질로 이루어진 도막의 경직성을 보완하여 도막의 크랙을 방지하고 신축성을 부여하기 위해 구비되는 것으로, 평균 길이가 10~20 ㎛(평균 두께 0.3~0.6 ㎛)이고, 섬유상의 형상을 가짐으로 보강재로서 기능을 부여할 수 있다. 티탄산칼륨은 5~15 중량%이 첨가되는 것이 바람직한데, 15 중량%를 초과하여 첨가되면 도막의 내수성이 저하되는 문제가 있고, 5 중량% 미만으로 첨가되면 크랙방지 효과를 기대할 수 없다.Then, potassium titanate, zirconium powder, pigment, and dispersant are mixed into the aqueous solution. The potassium titanate is provided to prevent cracking of the coating film and to impart elasticity by supplementing the rigidity of the coated film made of inorganic material. The potassium titanate has an average length of 10 to 20 占 퐉 (average thickness of 0.3 to 0.6 占 퐉) and has a fibrous shape And can function as a reinforcing material. It is preferable that 5-15 wt% of potassium titanate is added. If it is added in excess of 15 wt%, the water resistance of the coating film is deteriorated. If it is added in an amount of less than 5 wt%, a crack prevention effect can not be expected.
지르코늄 분말은 도막의 강도 및 내열 강도를 증진시키기 위해 구비되는 것으로, 용액에 균일하게 교반되도록 평균 입경이 15~30㎛ 범위로 형성되는 것이 바람직하다. The zirconium powder is provided to improve the strength and heat resistance of the coating film, and it is preferable that the zirconium powder is formed to have an average particle diameter of 15 to 30 mu m so as to be uniformly stirred in the solution.
본 발명에서 사용하는 안료는 다양한 색상의 발현을 위해 이산화티타늄, 카본블랙, 산화철황, 산화철적, 산화철흑 등을 단독 또는 혼합하여 형성되는 금속산화물계 안료 10~15 중량%가 첨가되는 것이 바람직한데, 15 중량% 초과하여 첨가되면 모재와 바인더와의 결합력의 약화를 초래하는 문제가 있고, 10 중량% 미만으로 첨가하면 색상이 제대로 발현되지 않게 된다. The pigment used in the present invention is preferably added with 10 to 15% by weight of a metal oxide-based pigment formed by singly or in combination of titanium dioxide, carbon black, iron oxide yellow, iron oxide red, If it is added in an amount of more than 15% by weight, there is a problem that the bonding force between the base material and the binder is weakened. When the amount is less than 10% by weight,
분산제는 수산화칼슘, 수산화나트륨 및 이들의 혼합물로 이루어진 군으로부터 선택된 하나 이상의 혼합물을 0.5~5중량%가 첨가된다. The dispersing agent is added in an amount of 0.5 to 5% by weight of at least one selected from the group consisting of calcium hydroxide, sodium hydroxide and mixtures thereof.
이하, 상기와 같이 이루어지는 본 발명의 구체적인 실시예를 살펴보기로 한다.Hereinafter, a specific embodiment of the present invention will be described.
