Description
본 발명은 셀렌(Se)을 포함하는 유기(鍮器)용 동합금 조성물에 관한 것이다. The present invention relates to a copper alloy composition for an organic (brass vessel) containing selenium (Se).
유기용에 적용되는 소재로는 스테인레스, 알루미늄, 플라스틱 등 다양한 소재를 들 수 있다. 그 중 특히 방짜유기가 항균성 및 고급스러운 색상으로 소비자들에게 혼수용품이나 제기류 및 수저용품으로 인기를 끌고 있다. 또한 이와 관련하여 방짜유기를 대체하여 황동, 백동 등을 포함한 기존 동합금 조성물로 제조된 유기 제품이 등장하고 있다. Materials for organic application include various materials such as stainless steel, aluminum, and plastic. Among them, especially organic antimicrobial and luxurious colors are popular with consumers as comics, raising and watering supplies. In this connection, organic products made of conventional copper alloy compositions including brass, white copper,
그러나 이러한 기존 동합금 조성물을 이용한 유기 제품은 방짜유기에 비해 색상면에서 차이가 나서 소비자들에게 만족을 주지 못하고 광택이 쉽게변한다However, the organic products using these conventional copper alloy compositions are different from the organic ones in terms of color, so they do not satisfy the consumers and the gloss easily changes
방짜유기란 구리(Cu)와 주석(Sn)을 78:22 중량 비율로 녹여 만든 합금된금속괴를 불에 달구어 가며 망치로 두드려 형태를 만든방짜유기 그릇. 징.꽹가리.악기이다. 주물유기는 쇳물을 일정한 틀에 부어 제조된 유기이다. 반방짜유기는 주물로 먼저 기본 형체를 만든 후, 방짜기법으로 구체적인 형상을 완성하는 방법으로 제조된 유기이다. An organic bowl made of metal alloy made by melting copper (Cu) and tin (Sn) at a weight ratio of 78:22 by burning with a hammer. It is a gong. Castings Organics are organics made by pouring molten metal into a certain mold. Semi-fungus organic is an organic produced by making a basic shape first as a casting and then completing a specific shape by a bamboo technique.
이러한 제조 방법상의 차이로 인해, 주물유기는 두 사람 또는 소수의 인원으로 제조할 수 있는 반면에, 방짜유기는 용해 → 네핌질 → 우김질 → 냄질 → 닥침질 → 제질 및 담금질 → 벼름질 → 가질의 여러 공정을 거쳐야 하기 때문에, 많은 인원과 숙련된 기술이 요구되어 금액이높다Due to the differences in the manufacturing method, the casting organic can be produced by two persons or a small number of people, while the organic waste is produced by various processes such as dissolution → nematidy → mulching → smelting → dipping → silage and quenching → , So it requires a lot of people and skilled skill, and the amount is high
방짜유기 제조시 숙련된 기술이 요구되는 이유는, 동합금에서 주석(Sn) 함량 증가시 취성을 야기하는 δ 상(phase)이 형성되어, 이로 인해 균열(crack)이 쉽게 발생하기 때문이다. 따라서, 제조 공정 중에 균열이 발생되지 않도록 β상이 존재하는 620~800℃ 구간에서 최소한의 가공도로 가공한 후, 열처리하고 다시 가공하는 과정을 반복하여야 한다. 따라서 이러한 가공 과정을 거쳐 고품질의 방짜유기를 제조하는 것은 전문 기능인이 아니면 수행하기 어려웠다. 또한, 유기용 동합금 조성물의 가공성이 좋지 않아서 가공이 더 어려운 이유도 있었다. 그러므로 가공성이 향상된 유기용 동합금 조성물의 개발이 요구되고 있다.A skilled artisan is required in the manufacture of organic materials because the δ phase which causes brittleness is formed when the tin (Sn) content of the copper alloy is increased, thereby causing cracks to occur easily. Therefore, it is necessary to repeat the processing of the minimum processing in the range of 620 to 800 ° C. in which the β phase is present so as not to generate cracks during the manufacturing process, and then the processing of heat treatment and re-processing is repeated. Therefore, it has been difficult to produce high-quality baked organic matter through such a processing step unless it is a specialized function. In addition, the processability of the organic copper alloy composition is not so good, and processing is more difficult. Therefore, development of an organic copper alloy composition having improved processability is required.
또한, 종래의 유기는 제작 초기의 황금색이 오래 유지되지 못하고 쉽게 변색되어, 유기의 가치를 떨어뜨리는 단점이 있었다. 따라서 변색 저항성의 개선이 요구되고 있다.In addition, the conventional organic material has a disadvantage in that the golden color at the initial stage of the production is not maintained for a long time and is easily discolored, thereby deteriorating the organic value. Therefore, improvement in discoloration resistance is required.
또한, 위생을 중요하게 생각하는 현대인들을 고려할 때, 유기 고유의 장점인 살균 및 해독 기능을 더욱 강화할 필요도 존재한다.Also, considering modern people who consider hygiene to be important, there is also a need to further strengthen the sterilization and detoxification function, which is an inherent advantage of organic matter.

If the content of nickel is less than 0.2% by weight, discoloration occurs in a humid atmosphere. If the content of nickel exceeds 1.0% by weight, the color of the final alloy is changed to excessively bright white. The thermal conductivity is lowered and the function of the organism as a material is deteriorated
셀렌(Se) Selenium (Se)
셀렌은 본 발명의 동합금 조성물에 있어서 가장 특징적인 성분이다. 셀렌은 동합금 조성물의 쾌삭성과 전연성을 좋게 하므로 가공성과 단조성을 향상시킨다. 또한, 동합금 조성물의 강도와 색상을 좋게 한다.Selenium is the most characteristic component in the copper alloy composition of the present invention.

In particular, it has been reported that selenium (Se) can reduce the risk of cancer by 50% due to its small amount of ingestion, and the US Food and Drug Administration has allowed the labeling of selenium as an anticancer substance. It also provides functions such as reproductive enhancement, removal of heavy metal characteristics, and anti-aging when absorbing a small amount. In addition, by activating cells in the human body, the skin elasticity is maintained and the immune system functions properly.
그러므로, 셀렌을 포함하는 유기는 인체에 매우 유익한 효과를 제공한다. Therefore, organics including selenium provide a very beneficial effect on the human body.
상기 셀렌은 0.01 내지 1.5 중량%로 포함되는 것이 바람직하며, 0.01 중량% 미만으로 포함되는 경우에는 상술한 기능의 발휘를 기대할 수 없으며, 1.5 중량%를 초과하여 포함되는 경우에는 동합금 조성물의 기계적 물성이 열화될 수 있다.

철은 니켈(Ni)과 함께 동합금 조성물의 강도를 향상시키고 내식성을 향상시키는 합금원소로서, 0.2 중량%보다 적게 포함되면 내식성 향상에 효과가 없으며, 1.0 중량%보다 많이 포함되면 높은 산화성으로 인해 용탕의 유동성 저하와 주괴내 기포를 발생시킬 수 있으므로 바람직하지 않다.Iron is an alloy element that improves the strength of the copper alloy composition and improves corrosion resistance together with nickel (Ni). When it is contained in an amount less than 0.2% by weight, iron is not effective for improving corrosion resistance. It is not preferable because the fluidity can be lowered and bubbles in the ingot can be generated.

(a) 상술한 구성 성분 비에 따른 용탕을 준비하여 주괴를 주조하는 단계; (a) casting an ingot by preparing a molten metal according to the composition ratio described above;
(b) 700~900℃의 온도 범위에서 1초 내지 1시간 동안 열간가공하는 단계; 및(b) hot working at a temperature in the range of 700 to 900 DEG C for 1 second to 1 hour; And
(c) 가공도 10~95%로 냉간가공하는 단계; 및 300~900℃의 온도 범위에서 소둔(annealing) 열처리하는 단계 (c) cold working at a machining degree of 10 to 95%; And an annealing heat treatment in a temperature range of 300 to 900 < 0 > C
상기 용탕 제조 단계에서는, 구리(Cu) 85~94.48중량%, 니켈(Ni) 0.2 내지 1.0 중량%, 및 철(Fe) 0.2 내지 1.0 중량%을 넣고 1200 내지 1350℃의 온도로 융해시킨다. 다음에 온도를 1200℃ 정도로 낮추고 알루미늄(Al) 5~9 중량%, 셀렌(Se) 0.01 내지 1.5 중량%, 은(Ag) 0.01 내지 1.5 중량%, 및 망간(Mn) 0.1 내지 1.5중량%를 용해하고, 탈산제로 인(P), 실리콘(Si), 마그네슘(Mg), 칼슘(Ca), 나트륨(Na)을 총량 0.1 내지 1.5 중량%로 첨가한다. 다음으로 1100~1200℃의 온도로 진정 처리를 5~10분간 유지하여 용탕을 준비한 후, 흑연 금형에 용탕을 주입하여 주괴를 주조한다.In the molten metal producing step, 85 to 94.48% by weight of copper (Cu), 0.2 to 1.0% by weight of nickel (Ni) and 0.2 to 1.0% by weight of iron (Fe) are melted at a temperature of 1200 to 1350 캜. Next, the temperature is lowered to about 1200 占 폚, and 5 to 9 wt% of aluminum (Al), 0.01 to 1.5 wt% of selenium (Se), 0.01 to 1.5 wt% of silver (Ag) and 0.1 to 1.5 wt% of manganese And phosphorus (P), silicon (Si), magnesium (Mg), calcium (Ca) and sodium (Na) are added as deoxidizing agents in a total amount of 0.1 to 1.5% by weight.
