저온 소성형 세라믹 코팅제 및 세라믹 코팅층 전사지 부착방법{Low temperature curing ceramic coating materials and bonding methods of transfer paper on the ceramic coating surface}Low temperature curing ceramic coating materials and bonding methods of transfer paper on the ceramic coating surface}

본 발명은 저온 소성형 세라믹 코팅제 및 전사지 부착방법에 관한 것으로, 보다 구체적으로는 결합제와 반응제 및 충진제의 입자 크기를 필러보다 상대적으로 작게 형성함으로써, 세라믹 코팅층 표면에 미세한 기공이 형성되도록 함과 동시에 다양한 입자 크기의 분포도를 형성하여 세라믹 코팅층의 내열성, 내오염성, 내약품성 향상은 물론 전사지의 부착력을 증대를 통해 전사품질을 향상시킬 수 있는 저온 소성형 세라믹 코팅제 및 세라믹 코팅층 전사지 부착방법에 관한 것이다.
The present invention relates to a low temperature calcined ceramic coating agent and a method for attaching a transfer paper. More specifically, by forming the particle size of the binder, the reactant and the filler relatively smaller than the filler, fine pores are formed on the surface of the ceramic coating layer. The present invention relates to a low temperature calcined ceramic coating agent and a ceramic coating layer transfer paper attaching method capable of improving transfer quality by forming a distribution chart of various particle sizes to improve heat resistance, stain resistance and chemical resistance of the ceramic coating layer, as well as to increase the adhesion of the transfer paper.

일반적으로 각종 조리용기는 다이 캐스팅 공법으로 성형된 알루미늄 재질 용기의 표면에 내열 코팅층 등을 형성하여 제작되어 지고 있으며, 이 내열 코팅층의 표면에는 전사지를 이용하여 다양한 문양 또는 무늬를 전사시켜 제품화하고 있다.In general, various cooking vessels are manufactured by forming a heat-resistant coating layer on the surface of an aluminum container molded by a die casting method, and various patterns or patterns are transferred to the surface of the heat-resistant coating layer using a transfer paper to produce products.

즉, 용기 내부면은 조리 중에 음식물이 달라붙지 않도록 불소 수지 도료 등과 같은 기능성 코팅을 마감 처리하고, 외측 표면에는 다양한 칼라를 형성하는 합성 수지계 내열 도료를 이용하여 코팅하고 있다.That is, the inner surface of the container is coated with a functional resin coating such as a fluororesin paint to prevent food from sticking during cooking, and a synthetic resin heat-resistant paint that forms various colors on the outer surface.

이때 외측 표면에는 시각적인 미감을 얻기 위하여 전사지를 이용하여 다양한 문양이나 무늬를 전사시켜 장식화 하고 있는 것이다.At this time, the outer surface is decorated by transferring various patterns or patterns using a transfer paper to obtain a visual aesthetic.

즉 용기 외측 표면에 칼라를 가지는 내열도료로 베이스 코팅을 실시한 후, 그 위에 전사지로 문양 또는 무늬를 전사하고, 전사층 위에 최종적으로 내열 도료를 도포하여 탑코팅(상도)를 실시하고 있다.That is, after the base coating is applied with a heat-resistant paint having a color on the outer surface of the container, the pattern or pattern is transferred onto the transfer paper, and the heat-resistant paint is finally applied on the transfer layer to perform top coating.

그러나 상기와 같은 합성 수지계 도료는 오염이 잘되고, 제조시 유해 환경 물질이 다량 배출될 뿐 아니라, 화재 발생시 유해가스가 다량 배출되는 문제점이 있었다.However, the synthetic resin paint as described above is well polluted, there is a problem that not only a large amount of harmful environmental substances are discharged during manufacture, a large amount of harmful gases are discharged in the event of a fire.

또한 내열성과 내약품성 등이 우수한 세라믹 코팅을 용기 외측면에 실시하는 경우에는 세라믹 코팅층이 가지는 내오염성과 소수성 등의 특성으로 인해 세라믹 코팅층에 대한 전사 무늬의 부착력이 낮아 쉽게 손상되거나 탈락됨으로써 전사 품질이 현저히 떨어지는 문제점이 있었다.In addition, when the ceramic coating with excellent heat resistance and chemical resistance is applied to the outer surface of the container, the transfer pattern is easily damaged or dropped due to the low adhesion force of the transfer pattern to the ceramic coating layer due to the contamination resistance and hydrophobicity of the ceramic coating layer. There was a significant drop.

따라서 세라믹 코팅층에는 전사지를 이용한 전사 방법을 적용할 수 없는 문제점이 있었고, 또한 이러한 전사품질 문제는 조리 용기 뿐만 아니라, 다리미 등과 같은 다양한 가열장치의 제품에도 동일하게 발생하기 때문에 이러한 전사지를 사용할 수 없는 문제점이 있었다.

이때 반응물질의 입자 크기는 결합제와 반응제 및 충진제의 상대적인 양에 따라 좌우된다.The particle size of the reactants then depends on the relative amounts of binder, reactant and filler.

즉 상기와 같이 결합제 35~45중량%, 반응제 10~20중량%, 충진제 5~15중량%로 한정하여 혼합하는 경우 반응물질은 필러 입자보다 대략 50% 이내의 소입자를 형성할 수 있다.That is, when the mixture is limited to 35 to 45 wt% of the binder, 10 to 20 wt% of the binder, and 5 to 15 wt% of the filler, the reactants may form small particles within about 50% of the filler particles.

여기서 본 발명의 세라믹 코팅제의 입자 분포도는 도 3에 도시되 바와 같은 입자 분포를 가지게 되는 것이다.Here, the particle distribution of the ceramic coating agent of the present invention is to have a particle distribution as shown in FIG.

또한 무기 안료 또는 필러(filler)는 통상적으로 1~15㎛의 입자 크기를 형성하게 되며, 제2조성물에 포함된 결합제와 반응제 및 충진제의 반응물질은 대략 0.01~10㎛의 입자 크기를 형성하게 되는 것이다.In addition, the inorganic pigment or filler (former) is usually formed a particle size of 1 ~ 15㎛, the reactant of the binder and the reactant and the filler included in the second composition to form a particle size of approximately 0.01 ~ 10㎛ Will be.

따라서 본 발명의 세라믹 코팅층(30)은 도 1,2에 도시된 바와 같이, 다양한 입자 크기의 분포도를 형성하게 되고, 이에 따라 코팅층 표면에 필러 입자(A)와 제2조성물의 소입자(B)가 불규칙하게 배치되면서 다수의 미세 기공을 형성하게 되는 것이다.Therefore, the ceramic coating layer 30 of the present invention, as shown in Figures 1 and 2, to form a distribution of various particle sizes, and thus the filler particles (A) and the small particles (B) of the second composition on the surface of the coating layer Is irregularly arranged will form a plurality of fine pores.

이때 세라믹 코팅층(30) 표면에 전사지를 이용하여 문양 또는 무늬를 전사시키는 경우, 전사지의 전사층(50)이 세라믹 코팅층(30)의 미세기공에 흡착되면서 보다 견고하게 전사되는 것이다.In this case, when the pattern or the pattern is transferred to the surface of the ceramic coating layer 30 by using the transfer paper, the transfer layer 50 of the transfer paper is more firmly transferred while being adsorbed to the micropores of the ceramic coating layer 30.

따라서 세라믹 코팅층(30)의 내열성, 내오염성, 내약품성 향상은 물론 전사지의 부착력이 증대되어 전사층(50)의 탈락이나 손상이 방지됨으로써, 전사품질을 향상시킬 수 있게 되는 것이다.Therefore, as well as improving the heat resistance, stain resistance, and chemical resistance of the ceramic coating layer 30, the adhesive force of the transfer paper is increased, thereby preventing the transfer layer 50 from falling off or being damaged, thereby improving the transfer quality.

한편 상기 증류수 또는 이온 교환수는 실란과의 몰의 비율이 3 이하이면 반응시간 내에 반응이 일어나지 않으며, 몰의 비율이 20 이상이면 반응시간과 코팅제의 사용 가능한 시간이 짧아진다.On the other hand, the distilled water or ion-exchanged water does not react within the reaction time when the molar ratio of silane is 3 or less, and the reaction time and the usable time of the coating agent are shortened when the molar ratio is 20 or more.

또한 pH가 2 이하이면 반응시간과 코팅제의 사용 가능한 시간이 짧아지게 되며, pH가 8 이상이면 반응이 거의 진행되지 않게 되므로, pH 4~5가 유지되도록 산도 조절을 하는 것이 바람직하다.In addition, when the pH is 2 or less, the reaction time and the usable time of the coating agent are shortened. When the pH is 8 or more, the reaction hardly proceeds, so it is preferable to adjust the acidity to maintain pH 4-5.

이하 도 4를 참조하여 본 발명의 세라믹 코팅층 전사지 부착방법을 설명한다.Hereinafter, a method of attaching the ceramic coating layer transfer paper of the present invention will be described with reference to FIG. 4.

도 4는 본 발명의 세라믹 코팅층 전사지 부착방법을 나타낸 흐름도이다.Figure 4 is a flow chart showing a ceramic coating layer transfer paper attaching method of the present invention.

도시된 바와 같이, 본 발명의 세라믹 코팅층 전사지 부착방법은 피도물 전처리단계(S10), 베이스 코팅단계(S20), 전사지 부착단계(S30), 필름 제거단계(S50), 및 건조단계(S60)로 구성된다.As shown, the ceramic coating layer transfer paper attaching method of the present invention is composed of the coating material pre-treatment step (S10), the base coating step (S20), the transfer paper attachment step (S30), film removal step (S50), and drying step (S60). do.

무늬를 전사시키고자 하는 피도물(조리용기 등)(10)은 세라믹 코팅제로 코팅을 실시하기 위해서 전처리 과정을 거치게 된다.The object to be transferred to the pattern (cooking vessel, etc.) 10 is subjected to a pretreatment process for coating with a ceramic coating agent.

즉 피도물(10)이 알루미늄인 경우에는 아노다이징 및 샌드블라스트 처리하며, 플라스틱 제품의 경우에는 플라즈마 처리하게 된다.That is, when the object 10 is aluminum, anodizing and sandblasting are performed, and in the case of plastic products, plasma treatment is performed.

알루미늄 아노다이징 처리의 경우 황산 용액에 알루미늄 제품을 침적한 상태에서 1~3 A/dm²의 전류를 가하면서 18~22℃의 온도 범위로 5~10분 동안 유지하여 산화피막층을 형성하는 아노다이징 단계를 거쳐 열처리로에서 250~350℃의 온도로 5~15분 동안 열충격을 가하고 수냉하여 산화피막층에 균열을 형성시키는 것이다.In the case of aluminum anodizing treatment, an anodizing step is performed in which an aluminum product is deposited in sulfuric acid solution while maintaining a temperature range of 18 to 22 ° C. for 5 to 10 minutes while applying a current of 1 to 3 A / dm². In a heat treatment furnace, a thermal shock is applied at a temperature of 250 to 350 ° C. for 5 to 15 minutes, followed by water cooling to form cracks in the oxide layer.

이때 제품에 산화피막층을 형성시킨 다음 열충격을 가하여 산화피막층의 균열을 유도함으로써 세라믹 코팅층(30)과의 접착력을 증대시키고, 또한 제품 표면의 변색 및 코팅제의 박리 현상을 방지하는 것이다.At this time, by forming an oxide layer on the product and then applying a thermal shock to induce the crack of the oxide layer to increase the adhesive strength with the ceramic coating layer 30, and also to prevent discoloration of the surface of the product and peeling of the coating agent.

또한 플라스틱 제품의 경우에는 50~200℃ 및 0.00001~100mbar의 플라즈마 환경에서 100~150초간 노출시킴으로써 계면에서 코팅제의 접착력이 향상되도록 하는 것이다.In addition, in the case of plastic products, the adhesion of the coating agent is improved at the interface by exposing it for 100 to 150 seconds in a plasma environment of 50 to 200 ° C. and 0.00001 to 100 mbar.

한편 베이스 코팅단계(S20)는 본 발명의 세라믹 코팅제로 상기 피도물(10)의 표면에 세라믹 코팅층(30)을 형성하는 것으로서, 피도물(10) 표면에 세라믹 코팅제를 도포한 후 200~350℃에서 15~20분 건조시켜 세라믹 코팅층(30)을 형성하는 것이다.On the other hand, the base coating step (S20) is to form a ceramic coating layer 30 on the surface of the workpiece 10 with the ceramic coating of the present invention, after coating the ceramic coating on the surface of the coating 10, 15 at 200 ~ 350 ℃ To dry for 20 minutes to form a ceramic coating layer (30).

상기와 같이 세라믹 코팅층(30)이 형성되면 전사지를 세라믹 코팅층(30)에 부착시킨다.When the ceramic coating layer 30 is formed as described above, the transfer paper is attached to the ceramic coating layer 30.

전사지는 통상적으로 보호층과 무늬층 및 필름층이 순차적으로 적층 형성되고, 결합제는 주로 실리콘 수지, 아크릴 수지, 변성 수지가 사용되며, 충진제로는 연출하고자 하는 색상에 따라 다양한 무기 안료의 선택이 가능하다.The transfer paper is typically formed by sequentially laminating a protective layer, a pattern layer, and a film layer, and a binder is mainly a silicone resin, an acrylic resin, or a modified resin, and as a filler, various inorganic pigments can be selected according to the color to be produced. Do.

따라서 전사지 부착은 먼저 보호층을 제거한 후 무늬층이 세라믹 코팅층(30)에 접착되도록 전사지를 세라믹 코팅층(30)에 부착시킨다.Therefore, the transfer paper is attached to the ceramic coating layer 30 to remove the protective layer first, and then the pattern layer is bonded to the ceramic coating layer (30).

따라서 피도물(10)의 세라믹 코팅층(30)을 청결하게 하고, 세라믹 코팅층(30) 표면에 전사지를 부착한 후 상온에서 10~15분 유지시킨다.Therefore, the ceramic coating layer 30 of the workpiece 10 is cleaned, and the transfer paper is attached to the surface of the ceramic coating layer 30 and maintained at room temperature for 10 to 15 minutes.

이후 필름 제거단계(S50)에서 전사지 최 상부층의 투명 필름을 제거한다.Then, in the film removing step (S50) to remove the transparent film of the uppermost layer of the transfer paper.

상기와 같이 필름이 제거시킨 후 세라믹 코팅층(30)을 180~190℃에서 10분간 건조시키는 건조단계(S60)를 거치면 되는 것이다.After removing the film as described above is to go through the drying step (S60) for drying the ceramic coating layer 30 at 180 ~ 190 ℃ for 10 minutes.

이때 전사층(50)의 무늬가 세라믹 코팅층(30)에 형성된 불규칙한 미세 기공에 흡착됨으로써, 견고하게 세라믹 코팅층(30)에 접착되는 것이다.At this time, the pattern of the transfer layer 50 is adhered to the irregular micro pores formed in the ceramic coating layer 30, thereby firmly adhered to the ceramic coating layer 30.

따라서 본 발명은 조리용기나 보일러 등과 같은 가열장치의 제품 표면에 세라믹 코팅층(30)을 형성하고 저온 건조형 전사지를 부착하여 다양한 무늬를 구현할 수 있으며, 내열 온도 300~400℃까지 사용할 수 있고, 또한 세라믹 코팅층(30)에 다양한 입자 크기의 분포도를 형성하도록 하여 표면에 미세기공을 형성함으로써, 세라믹 코팅층(30)의 표면적 증대를 통해 세라믹 코팅층(30)과 전사층(50)의 접착력을 증대시킬 수 있게 되고 이로 인해 전사층(50)의 손상이나 탈락을 방지하여 전사품질을 향상시킬 수 있게 되는 것이다.Therefore, the present invention can form a ceramic coating layer 30 on the surface of the product of a heating device such as a cooking vessel or a boiler and attach a low temperature dry type transfer paper to implement various patterns, and can be used up to 300 ~ 400 ℃ heat resistance temperature, By forming micropores on the surface by forming a distribution of various particle sizes in the ceramic coating layer 30, the adhesion between the ceramic coating layer 30 and the transfer layer 50 can be increased by increasing the surface area of the ceramic coating layer 30. This prevents damage or dropping of the transfer layer 50, thereby improving the transfer quality.

이상, 상기의 실시 예는 단지 설명의 편의를 위해 예시로서 설명한 것에 불과하므로 특허청구범위를 한정하는 것은 아니며, 본 발명의 기술 범주 내에서 다양한 변형이 가능할 것이다.
