Description

귀금속 공예용 귀금속 점토 조성물 및 그 제조방법{Nobel metal clay compositions for nobel metal articles, and their preparation method}Nobel metal clay compositions for nobel metal articles, and their preparation method

본 발명은 공예적 요소가 큰 귀금속 조형물을 제작하기 위한 소재로 사용하는 귀금속 공예용 귀금속 점토 조성물 및 그 제조방법에 관한 것이다.The present invention relates to a precious metal clay composition and a method for producing the precious metal craft used as a material for producing a precious metal sculpture large craft elements.

현재 귀금속 분말과 수용성 셀룰로스계 수지, 아크릴 수지, 폴리비닐알콜, 합성고무, 왁스, 폴리에틸렌 수지, 프탈산에스테르, 고급지방산, 지방산에스테르, 유동파라핀, 전분 등을 바인더로 사용하는 점토조성물을 사용하여 귀금속 조형물을 제조하는 방법이 시행되고 있다.Precious metal moldings using clay compositions using precious metal powders, water-soluble cellulose resins, acrylic resins, polyvinyl alcohols, synthetic rubbers, waxes, polyethylene resins, phthalic acid esters, higher fatty acids, fatty acid esters, liquid paraffin, and starch as binders. The method of manufacturing the is implemented.

그러나, 상기한 종래의 귀금속 점토는 귀금속 현시세의 10배에 가까운 높은 가격 때문에 일반인들이 쉽게 이용할 수 없었으며, 조형시 쉽게 부서지고 손에 묻어나 일정한 교육을 거쳐야만 자유로이 원하는 형태로 제작할 수 있게 되는 단점이 있었다.However, the above-mentioned conventional precious metal clay was not easily available to the general public due to the high price of about 10 times higher than the current price of the precious metal, and it was easily broken and buried during molding, so that it could be freely produced in a desired form only after a certain education. .

또한, 바인더로 유지류를 포함하는 경우 소성시에 많은 검은 연기가 발생하는 문제점도 있었다.In addition, in the case of containing fats and oils as a binder, there was also a problem that a lot of black smoke occurs during firing.

따라서, 본 발명의 목적은 상기와 같은 문제점을 해결하기 위한 것으로, 가격이 저렴하고 손에 잘 묻어나지 않으면서 표면이 쉽게 건조해지지 않는 귀금속 공예용 귀금속 점토 조성물을 제공하는 것이다.Accordingly, an object of the present invention is to solve the above problems, to provide a precious metal clay composition for precious metal crafts that the surface is not easily dried while being cheap and not smeared on the hand.

본 발명의 다른 목적은 조형 뿐 아니라, 순 귀금속으로 만들어져 있는 제품의 땜질이나 물을 부가하여 원하는 농도의 페이스트로 사용하는 등 다용도로 사용할 수 있는 귀금속 점토 조성물을 제공하는 것이다.Another object of the present invention is to provide a noble metal clay composition which can be used not only for molding but also for use as a paste of desired concentration by adding soldering or water of a product made of pure noble metal.

본 발명의 또 다른 목적은 유지류를 포함하지 않아 소성 시에 연기의 발생이 거의 없이 안전하게 사용할 수 있는 귀금속 점토 조성물을 제공하는 것이다.It is another object of the present invention to provide a precious metal clay composition which does not include oils and fats and can be used safely with little generation of smoke during firing.

상기 본 발명의 목적은 한천 0.5-2.0중량%, 젤라틴 0.5-2.0중량%, 설탕 3.0-12중량% 및 나머지의 귀금속 분말로 구성되는 귀금속 점토 조성물에 의해 달성된다.The object of the present invention is achieved by a precious metal clay composition consisting of 0.5-2.0% by weight agar, 0.5-2.0% by weight gelatin, 3.0-12% by weight sugar and the rest of the precious metal powder.

본 발명에 사용되는 귀금속 분말은 순도 99.9% 이상의 순은 분말, 순금 분말, 구리분말, 백금분말 등으로, 평균입경 1마이크론 미만의 미분을 사용한다.The precious metal powder used in the present invention is a pure silver powder, a pure gold powder, a copper powder, a platinum powder, or the like having a purity of 99.9% or more, and a fine powder having an average particle diameter of less than 1 micron.

상기 귀금속 점토 조성물에서 한천과 젤라틴은 순귀금속 점토 조성물의 점착력과 탄력을 주는 역할을 한다. 이러한 성질은 조형 작업시 자유로이 형태를 잡을 수 있도록 하며, 건조 시 강도가 높아져도 실수로 조형물을 떨어뜨렸을 때 파손되지 않도록 한다. 그리고 젤라틴의 경우 점토 표면에 균열이 생기는 것을 방지해 준다. 그러나, 젤라틴의 양이 2중량%를 넘을 경우 점토의 점착성은 좋으나 건조가 오래 걸리고 소성 후 심한 수축에 의해 조형물의 형태에 변형이 생긴다. 한천과 젤라틴의 총량의 비율이 1.0중량% 미만일 경우 순귀금속 점토의 점착성이 충분하지 못하며, 4중량% 이상일 때에는 소성 후 조형물에 수축이 심해지면서 변형이 생긴다. 따라서, 한천과 젤라틴은 각각 0.5-2.0중량%의 양으로 사용하는 것이 바람직하다.Agar and gelatin in the precious metal clay composition serves to give adhesion and elasticity of the pure precious metal clay composition. This property makes it possible to freely shape the molding work, and it does not break when the product is accidentally dropped even when the strength is increased during drying. And gelatin prevents the cracks on the clay surface. However, when the amount of gelatin exceeds 2% by weight, the adhesion of clay is good, but it takes a long time to dry, and deformation of the sculpture is caused by severe shrinkage after firing. If the ratio of the total amount of agar and gelatin is less than 1.0% by weight, the adhesion of the pure noble metal clay is not sufficient, and when it is more than 4% by weight, shrinkage occurs in the sculpture after firing and deformation occurs. Therefore, agar and gelatin are preferably used in amounts of 0.5 to 2.0% by weight, respectively.

한천은 실한천, 각한천, 가루한천 등을 선택하여 사용할 수 있으며, 젤라틴도 판젤라틴, 가루젤라틴 등을 선택하여 사용할 수 있으며, 한천이나 젤라틴의 종류나 형태에 제한은 없다.Agar can be used to select real agar, gaek agar, powder agar, and the like, gelatin can also be used to select pan gelatin, powder gelatin, etc., there is no limitation on the type or form of agar or gelatin.

본 발명의 귀금속 점토는 냉수나 온수에 잘 녹아 소성 전 이미 만들어 건조해 놓은 조형물도 적당한 물을 이용하여 수정, 변형이 가능하다. 또한 금속형태의 귀금속을 서로 붙이려고 할 때에도 안전하게 땜 작업을 할 수 있다. 이는 설탕이 적당한 수분에 의해 점성이 증대됨과 동시에 젤라틴,한천과 함께 건조 시에는 단단하게 강도가 높아지는 성질을 이용한 것이다. 그러나, 설탕량이 12중량%를 넘게되면 작업 시 끈적임이 많아져 불편하므로 설탕은 3.0-12중량%의 양으로 사용하는 것이 바람직하다.The precious metal clay of the present invention is well melted in cold water or hot water, and already made and dried before firing can be modified and modified using suitable water. In addition, it can be safely soldered when trying to glue the precious metals in the form of metal. This is due to the fact that the sugar is increased in viscosity by moderate moisture and at the same time, the strength is increased when it is dried with gelatin and agar. However, when the amount of sugar exceeds 12% by weight, it is inconvenient to increase the stickiness during work, so it is preferable to use the sugar in an amount of 3.0-12% by weight.

본 발명의 귀금속 점토를 제조하는 방법은 귀금속 분말과 유기계 바인더 총중량에 대해, 각각 한천 0.5-2.0중량%, 젤라틴 0.5-2.0중량%, 설탕 3.0-12중량% 범위 내에서, 먼저 한천을 상기 분량만큼 정수된 물에 2시간 이상 불린 것과, 젤라틴을 상기 분량만큼 정수된 물에 5분 이상 불린 것을 한천과 젤라틴 총량의 2배 정도의 정수된 물과 함께 용기에 넣어 100℃ 내외에서 완전하게 녹인다. 그리고 한천과 젤라틴이 완전히 용해된 용기에 상기 분량만큼의 설탕을 함께 넣어 완전히 녹인 후 10분 정도 끓여 준다. 그 후, 용기의 온도를 높이기 위해 사용되었던 외부 에너지를 차단하고 평균 입경 1마이크론 미만의 귀금속 분말을 넣어 완전하게 혼합한다. 이때 사용되는 용기는 온도의 변화가 천천히 생기는 두꺼운 것을 사용하는 것이 좋다. 용기가 다 식을 때까지 혼합물 총량의 10% 정도의 수분을 유지하면서 계속하여 혼합하는 것이 중요하며 용기가 식은 후에도 수분이 6-7% 정도가 될 때까지 혼합하여 주면 적당한 탄력을 지닌 부드러운 귀금속 점토가 만들어진다.The method for preparing the precious metal clay of the present invention is based on the total weight of the precious metal powder and the organic binder, respectively, in the range of 0.5-2.0% by weight of agar, 0.5-2.0% by weight of gelatin, and 3.0-12% by weight of sugar. Soaked in purified water for 2 hours or more and gelatin soaked in purified water for 5 minutes or more in a container with purified water of about 2 times the total amount of agar and gelatin is completely dissolved at about 100 ℃. And agar and gelatin completely dissolved in the container with the amount of the above amount together to melt completely and boil for 10 minutes. Thereafter, the external energy used to raise the temperature of the vessel is shut off and precious metal powder with an average particle diameter of less than 1 micron is added and mixed thoroughly. At this time, it is better to use a thick container that slowly changes in temperature. It is important to continue mixing while maintaining the water content of about 10% of the total amount of the mixture until the container cools down. If the container is mixed until the moisture reaches 6-7%, soft precious metal clay with moderate elasticity Is made.

본 발명의 귀금속 점토 조성물은 조형 후 약 10분정도 18℃ 이상의 실온에서 그대로 자연건조 후, 이미 예열되어 있는 고온에서 바로 소성가능하다. 기존의 가스버너, 가스렌지, 전자렌지, 전기로 등을 이용하여 700℃에서 15-30분 정도 소결 후 귀금속 공예품을 완성할 수 있다.The precious metal clay composition of the present invention can be fired immediately at high temperature already preheated after natural drying as it is at room temperature of 18 ° C. or higher for about 10 minutes after molding. Precious metal crafts can be completed after sintering at 700 ℃ for 15-30 minutes using existing gas burners, gas stoves, microwave ovens, and electric furnaces.

본 발명의 실시예에서 조형물의 소성 후의 강도는 특별하게 다루지 않았는데, 그 이유는 위의 실험방법과 같이 소성 후 순수한 순은 금속만이 결합한 상태가 되었으며, 소성 후의 강도를 높이는 방법의 예로서, 귀금속 세공에서 쓰이는 스텐인레스 스틸 재질의 광쇠 등으로 필요한 만큼 마찰을 가하였을 때 강도가더욱 높아짐을 발견할 수 있었다.In the embodiment of the present invention, the strength after firing of the molded article was not particularly handled, because the pure pure silver metal was bound after firing as in the above experimental method, and as an example of a method of increasing the strength after firing, It was found that the strength was increased when the friction was applied as necessary, such as the stainless steel of the iron used in the.

상기한 바와 같이, 본 발명의 귀금속 점토 조성물은 기존의 방법보다 제조공정이 간단하고 제조시간이 짧다. 또, 조형 시에 고무점토와 같은 질감으로 손에 잘 묻어나지 않으면서 특별한 도구 없이 자유롭게 조형이 가능하다. 또한, 점토가 탄성이 있어 조형물을 바닥에 떨어뜨렸을 경우에도 부서질 위험이 적다. 그리고 기존의 귀금속 점토 조성물을 이용하여 조형물을 조형할 때에는 소성 전에 고온의 전기드라이기 등을 이용하여 10분 이상 열풍건조를 한 후에 소성을 하여야 했으나, 본 발명의 귀금속 점토 조성물은 실온에서 약 10분정도의 자연건조만 시키면 되고, 소성도 종래의 조성물보다 낮은 온도에서 가능하게 되었다. 또한, 물에 잘 용해되는 성질이 있어 본 발명의 귀금속 점토에 필요한 수분을 첨가하여 페이스트 상태로 용해 후 이를 이용하여 금속 상호간의 부착이나 파손된 부분의 땜 작업을 할 수 있다.As described above, the noble metal clay composition of the present invention is simpler in production process and shorter production time than the conventional method. In addition, it is possible to freely mold without special tools without smearing it on the hand with a texture like rubber clay at the time of molding. In addition, the clay is elastic, so there is less risk of fracture even when the sculpture is dropped on the floor. And when molding the molding using the existing noble metal clay composition, after firing after hot-air drying for 10 minutes or more using a high-temperature electric dry before firing, the noble metal clay composition of the present invention is about 10 minutes at room temperature It only needs to be naturally dried, and the firing is also possible at a lower temperature than the conventional composition. In addition, it has a property of dissolving well in water, it is possible to add the necessary water to the precious metal clay of the present invention to dissolve in a paste state, and then use it to solder or attach the broken parts to each other.

또한, 유지류를 포함하지 않아 소성 시에 연기의 발생이 거의 없어 안전하게 사용할 수 있는 장점이 있다.In addition, it does not include oil and fat has the advantage that there is little generation of smoke during firing can be used safely.

본 발명의 실시예에서는 비교적 저렴하여 가장 흔히 이용되는 은점토에 대해서만 기술하였으나, 금, 백금 등 다른 귀금속 점토의 적용이 가능함은 물론 본 발명의 사상과 특허청구범위를 벗어나지 않는 한 다양한 변형과 적용이 가능하다.In the embodiment of the present invention is described only for the most commonly used silver clay relatively inexpensive, it is possible to apply other precious metal clay, such as gold, platinum, as well as various modifications and applications without departing from the spirit and claims of the present invention It is possible.
