일반적으로 금속제품은 스테인리스, 철, 니켈 등 종류가 다양하나 티타늄만큼 내부식성이 강하고 가벼우며 인체에 친화적인 것은 드물다.Generally, metal products have various kinds such as stainless steel, iron, and nickel, but they are hardly corrosion-resistant, light and friendly to human body like titanium.

이하에서는 양호한 실시 예와 관련하여 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the preferred embodiments.

먼저 Ti분말사출성형 다공금속화를 제조하기 위한 원재료에 대해 설명한다.First, the raw material for producing the Ti powder injection molding porous metallization will be described.

본 발명에서는 Ti분말사출성형 재료로서 Ti를 사용하므로 티타늄은 비중이 4.51로 강, Nickel의 약1/2, 스테인리스 강 및 철의 약 60%정도 이므로 조립, 설치, 이동이 용이하고 순 티타늄은 보통강 정도, 티타늄 합금은 특수강에 필적하는 강도를 갖고 있다. 티타늄의 최대특징은 스테인리스강보다 우수한 내식성을 갖고 있다는 점이다. 티타늄은 침식에 대하여 다른 금속에 비하여 탁월하게 우수한 저항성을 갖고 있다. 또한 모래에 의한 침식(Sand erosion)에도 우수한 성질을 갖고 있다. In the present invention, since Ti is used as the Ti powder injection molding material, titanium has a specific gravity of 4.51, which is about 1/2 of steel, Nickel, and about 60% of stainless steel and iron, and thus easy to assemble, install and move, and pure titanium is usually used. As much as steel, titanium alloys have strengths comparable to that of special steels. The biggest feature of titanium is that it has better corrosion resistance than stainless steel. Titanium has excellent resistance to erosion compared to other metals. It also has excellent properties in sand erosion.

사출 시 티타늄의 유동성 및 사출을 돕기 위해 PP, PEG를 활용하여 티타늄 대 PP 대 PEG의 비율을 45~ 60:15~ 30:25~ 40의 합성으로 더욱 사출을 잘 되게 하는 이점이 있다. In order to aid the fluidity and injection of the titanium during injection, the use of PP, PEG has the advantage of better injection by the synthesis of titanium to PP to PEG ratio of 45 ~ 60:15 ~ 30:25 ~ 40.

상기와 같이 원재료를 선정한 후 선정한 재료를 혼합하는데 티타늄의 입도가 10~ 100㎛의 분말을 PP, PEG와 혼합하기 위하여 더블콘 타입 혼합기를 사용하여 혼합한다. After selecting the raw materials as described above, the selected materials are mixed, and a powder having a particle size of 10 to 100 μm is mixed using a double cone type mixer to mix the powder with PP and PEG.

이어서, 혼합된 원재료를 압출기를 이용하여 150℃~ 200℃ 에서 200~ 500rpm 으로 압출을 하여 200℃~ 230℃ 의 조건의 사출기를 이용하여 성형체를 제조한다.Subsequently, the mixed raw materials are extruded at 200 to 500 rpm at 150 ° C. to 200 ° C. using an extruder, and a molded product is manufactured using an injection machine having a condition of 200 ° C. to 230 ° C.

이때 사출기는 플라스틱 사출기로 행하며, 성형체를 제조 후 PEG를 용매추출하기 위한 용매로써 알코올을 사용하여 50~ 80℃ 에서 시간을 변화시켜 추출 후 5~ 12시간 건조시켜 PEG을 용매 추출한다. 용매 추출 후 열분해를 30분~ 120분 유지하면 PP를 열분해 할 수 있다.In this case, the injection molding machine is a plastic injection molding machine, and after manufacturing the molded product, the solvent is extracted by changing the time at 50 to 80 ° C. using alcohol as a solvent for solvent extraction, and drying the extract for 5 to 12 hours. If pyrolysis is maintained for 30 to 120 minutes after solvent extraction, PP can be pyrolyzed.

열분해 후 성형체를 1200℃~ 1250℃ 에서 30분~ 180분을 소결을 하는데 소결의 분위기는 진공 분위기로 소결을 행하여 기공률 20%~ 50% 정도의 Ti분말사출성형 다공금속화 소결체를 형성한다. 이 소결체는 완성품으로서 도 1에 도시된 바와 같이 다수의 기공(12)을 갖는 다공화된 티타늄 100%로 남는다. 여기서, 부재번호 13은 티타늄 표면이다.After pyrolysis, the molded body is sintered at 1200 ° C to 1250 ° C for 30 minutes to 180 minutes, and the sintering atmosphere is sintered in a vacuum atmosphere to form a Ti powder injection molding porous metallized sintered body having a porosity of about 20% to 50%. This sintered body remains 100% of the porous titanium with multiple pores 12 as shown in FIG. Here, reference numeral 13 is a titanium surface.

(실시 예 1)(Example 1)

티타늄, PP, PEG의 비율이 50:20:30의 분말을 190℃ 에서 15분정도 혼합기를 이용해서 혼합한 후, 180℃ 에서 300rpm으로 압출을 한다. 압출 후 사출기를 이용하여 원하는 형상을 220℃ 에서 사출을 하여 성형체를 제조한다.Titanium, PP, PEG in a powder ratio of 50:20:30 is mixed at 190 ° C. for about 15 minutes using a mixer, and then extruded at 180 ° C. at 300 rpm. After extrusion, a desired shape is injected at 220 ° C. using an injection machine to prepare a molded product.

이어서 성형체로부터 PEG를 용매추출하기 위한 용매로써 알코올 사용하여 60℃ 에서 시간을 변화시켜 추출 후 10시간 건조시켜 PEG을 용매추출 하며 700℃ 에서 90분 유지하여 PP를 열분해 한다. Subsequently, using PEG as a solvent for solvent extraction of the PEG from the molded body, the time was changed at 60 ° C. to be dried for 10 hours after extraction, and the solvent was extracted for PEG, and the temperature was maintained at 700 ° C. for 90 minutes to thermally decompose PP.

이어서 진공분위기 하에서 로터리 펌프로 수소를 제거하면서 1200℃ 온도에서 50~90분간 소결을 행하여 기공률 50%의 정밀한 다공재료를 제조하였다. Subsequently, sintering was carried out at a temperature of 1200 ° C. for 50 to 90 minutes while removing hydrogen with a rotary pump under a vacuum atmosphere, thereby preparing a precise porous material having a porosity of 50%.

(실시 예 2)(Example 2)

티타늄, PP, PEG의 비율이 60:15:25의 분말을 190℃ 에서 20분정도 혼합기를 이용해서 혼합한 후, 200℃ 에서 400rpm으로 압출을 한다. 압출 후 사출기를 이용하여 원하는 형상을 210℃ 에서 사출을 하여 성형체를 제조한다.Titanium, PP, PEG in a ratio of 60:15:25 is mixed at 190 ° C. for about 20 minutes using a mixer, and then extruded at 200 ° C. at 400 rpm. After extrusion, a desired shape is injected at 210 ° C. using an injection machine to prepare a molded product.

이어서 성형체로부터 PEG를 용매추출하기 위한 용매로써 알코올 사용하여 70℃ 에서 시간을 변화시켜 추출 후 8시간 건조시켜 PEG을 용매추출 하며 600℃ 에서 60분 유지하여 PP를 열분해 한다. Subsequently, using PEG as a solvent for solvent extraction of PEG from the molded body, the time was changed at 70 ° C. to be dried for 8 hours, followed by drying the PEG for 60 minutes at 600 ° C. to thermally decompose PP.

이어서 진공분위기 하에서 로터리 펌프로 수소를 제거하면서 1250℃ 온도에서 60분~120분간 소결을 행하여 기공률 40%의 정밀한 다공재료를 제조하였다. Subsequently, sintering was carried out at a temperature of 1250 ° C. for 60 minutes to 120 minutes while hydrogen was removed with a rotary pump in a vacuum atmosphere to prepare a precise porous material having a porosity of 40%.

Ti사출성형 다공금속화를 제조한 후, 향료를 강제적으로 침투시키는 공정을 실시하거나 향료의 액상에 담가 주입시키는 과정을 행하여 향기를 내는 다공금속화를 제조하였다.  After preparing the Ti injection-molded porous metallization, a porous metallization having an aroma was produced by performing a process of forcibly infiltrating the perfume or injecting it into the liquid phase of the perfume.

본 발명의 제조방법에 따른 티타늄은 부품소재를 비롯하여 생활용품에 이르기까지 많이 필요 필요로 하고 있으나 소재의 가격, 제조상의 문제 등으로 저변 확대에 충족을 못시켜주는 입장이며 티타늄 사출공법을 새롭게 개발함으로써 생산가격 측면이나 입체적 모형으로 소재산업 전반에 걸쳐 값싸고 가벼운 티타늄의 새로운 시장으로 발전 될 것이다. Titanium according to the manufacturing method of the present invention requires a large number of parts and materials, such as daily necessities, but is unable to meet the expansion of the base due to the price of the material, manufacturing problems, etc. by newly developing a titanium injection method In terms of production price or three-dimensional model, it will develop into a new market of cheap and light titanium throughout the material industry.

특히, 기존의 다이캐스팅 주조와는 달리 금속을 저온에서 성형 사출 할 수 있어 플라스틱 사출 방식에 의한 티타늄 사출방법은 손쉽게 제품을 생산할 수 있고 금속 소재에 대한 사회 통념을 바꾸는 계기가 되리라 믿는다. In particular, unlike conventional die-casting casting, the metal can be molded at low temperature so that the titanium injection method by plastic injection method can be easily produced and change the social notion about metal materials.
