Description
본 발명은 경량, 고강성 및 전자파를 차단할 수 있는 금속섬유를 함유한 수지를 생산할 수 있는 금속섬유를 함유한 수지 및 그 수지의 제조방법에 관한 것으로, 보다 더 상세하게는 미세하게 컷팅된 금속섬유를 생산할 제조품의 종류에 따라 수지와의 혼합 비율을 달리하여 혼련(混練)함으로서, 경량, 고강성 및 전자파를 차단할 수 있는 금속섬유를 함유한 수지를 생산하여 이 수지를 이용한 제조물을 생산할 수 있도록 하는 금속섬유를 함유한 수지 및 그 수지의 제조방법에 관한 것이다.The present invention relates to a resin containing a metal fiber capable of producing a resin containing a metal fiber capable of blocking light, high rigidity and electromagnetic waves, and a method for producing the resin, and more particularly finely cut metal fiber By kneading at different mixing ratios with the resin according to the type of manufactured product to produce the product, it is possible to produce a resin containing a metal fiber which is lightweight, high rigidity and can block electromagnetic waves to produce a product using the resin A resin containing metal fibers and a method for producing the resin.
일반적으로, 합성수지를 사출성형하여 TV, 휴대폰, 컴퓨터 등의 전기ㆍ전자기기의 케이스 등을 생산하게 되는데, 이러한 전기ㆍ전자기기에서는 다량의 전자파가 발생하여 이 전자파를 차단하기 위해 금속(동판 등)으로 된 금속막이나, 구리 등이 도금된 섬유를 기기의 내부에 별도로 설치하였다.Generally, synthetic resins are injection molded to produce cases of electric and electronic devices such as TVs, mobile phones, and computers. In such electric and electronic devices, a large amount of electromagnetic waves are generated to block the electromagnetic waves. A metal film, a copper plated copper, and the like were separately installed inside the apparatus.
그러나, 전자파를 차단하기 위해 별도의 부재를 사용함으로써, 기기의 무게가 증가하게 되고, 별도의 부재를 설치하기 위해 여러 작업공정을 거쳐야 하며, 별도 부재의 설치로 인한 기기의 부피도 증가하게 된다.However, by using a separate member to block the electromagnetic waves, the weight of the device is increased, it is required to go through several work processes to install a separate member, the volume of the device due to the installation of the separate member also increases.
또한, 강도를 요하는 공업재료나 구조재료로 합성수지를 사용하기 위해서는 분자량이 몇 십∼몇 백 정도의 저분자(低分子) 물질인 종래의 플라스틱과는 달리, 몇 십만∼몇 백만이나 되는 고분자물질로 되어 강도·탄성(彈性)뿐만 아니라, 내충격성(耐衝擊性)·내마모성(耐磨耗性) 등이 우수한 고가의 엔지니어링플라스틱을 사용함으로써, 제조물의 원가가 증대되는 문제점이 있었다.In addition, in order to use synthetic resin as an industrial material or a structural material requiring strength, unlike a conventional plastic having a molecular weight of several tens to several hundreds, it is a polymer material of several hundred thousand to several million. The use of expensive engineering plastics with excellent strength, elasticity, impact resistance, abrasion resistance, and the like has a problem of increasing the cost of manufactured products.
본 발명은 위와 같은 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은, 전기ㆍ전자기기에서 발생하는 전자파를 차단하기 위한 별도 부재의 사용없이도 용이하게 전자파를 차단할 수 있는 금속섬유를 함유한 수지 및 그 수지의 제조방법을 제공하는데 있다.The present invention has been made to solve the above problems, an object of the present invention, a resin containing a metal fiber that can easily block electromagnetic waves without the use of a separate member for blocking electromagnetic waves generated in electrical and electronic equipment And a method for producing the resin.
또한, 본 발명의 다른 목적은, 경량이면서도 고강성의 성질을 갖도록 하여 공업재료나 구조재료로 용이하게 사용할 수 있도록 하는 금속섬유를 함유한 수지 및 그 수지의 제조방법을 제공하는데 있다.Further, another object of the present invention is to provide a resin containing a metal fiber and a method for producing the resin that can be easily used as an industrial material or a structural material to have a lightweight and high rigidity property.
또한, 본 발명의 또 다른 목적은, 알루미늄이나 마그네슘의 사출성형 제품과유사한 특성을 가지면서도 생산 설비의 투자 비용이 절감되는 금속섬유를 함유한 수지 및 그 수지의 제조방법을 제공하는데 있다.It is still another object of the present invention to provide a resin containing a metal fiber and a method for producing the resin, which have properties similar to those of an injection molded product of aluminum or magnesium, while reducing the investment cost of the production equipment.

이하에서는 예시도면을 참조하여 본 발명의 바람직한 실시예에 대하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도1은 본 발명에 따른 금속섬유를 함유한 수지의 제조방법에 대한 공정도를 나타낸 것으로,Figure 1 shows a process diagram for a method for producing a resin containing a metal fiber according to the present invention,
도1에 도시한 바와 같이, 본 발명은 마그네슘 또는 알루미늄 재질로 된 1~150미크론(㎛) 범위내의 직경을 가진 금속섬유를 생산하는 생산단계(100)와;이 생산단계(100)를 거친 금속섬유를 일정길이(수㎛ ~ 수십㎛)로 컷팅하는 컷팅단계(120)와;이 컷팅단계(120)를 거친 일정길이의 금속섬유와 수지시료를 혼합한 후, 혼련(混練)하는 혼합단계(140)와;이 혼합단계(140)를 거쳐서 생성된 금속섬유를 함유한 수지를 사출성형하여 제조품을 생산하는 성형단계(160)으로 이루어진다.As shown in Figure 1, the present invention is a production step (100) for producing a metal fiber having a diameter in the range of 1 ~ 150 microns (μm) made of magnesium or aluminum material; Cutting step 120 for cutting the fibers to a predetermined length (several to several tens of micrometers); After mixing the metal fiber and the resin sample of a certain length passed through the cutting step 120, the mixing step of kneading (() 140; and a molding step 160 for producing a manufactured product by injection molding a resin containing a metal fiber produced through the mixing step 140.
상세하게 설명하면, 생산단계(100)에서는 후술할 성형단계(160)를 거쳐서 성형되는 제조품에 따라 금속섬유의 직경을, 초정밀 제품에 사용될 경우에는 1~10미크론(㎛) 범위내로 생산하고, 정밀 제품에 사용될 경우에는 11~50미크론(㎛) 범위내로 생산하고, 일반 제품에 사용될 경우에는 51~150미크론(㎛) 범위내로 생산하여 후술할 혼합단계(140)를 거쳐서 생성되는 수지내의 금속섬유간의 간격을 최소화하여 전자파의 차폐 효과를 증대시킨다.In detail, the production step 100 produces the diameter of the metal fiber in the range of 1 to 10 microns (μm) when used in ultra-precision products according to the manufactured product to be molded through the forming step 160 to be described later, When used in the product is produced in the range of 11 ~ 50 microns (㎛), when used in the general product is produced in the range of 51 ~ 150 microns (㎛) between the metal fibers in the resin produced through the mixing step 140 to be described later Minimize the gap to increase the shielding effect of electromagnetic waves.
또한, 금속섬유의 재질은 마그네슘 또는 알루미늄을 사용하는 것이 바람직하며, 이는 마그네슘 및 알루미늄이 전자파에 대한 차폐효과가 크고, 중량이 가벼워서 모든 제조품에 사용이 가능하게 된다.In addition, it is preferable to use magnesium or aluminum as the material of the metal fiber, which has a large shielding effect against electromagnetic waves and light weight, so that it can be used in all manufactured products.
한편, 위와 같이 금속섬유를 생산하는 방법으로는 본 발명의 출원인이 출원한 특허출원번호 1020020019635호 '절연된 금속회전몸체와 그것을 이용한 금속섬유의 제조장치 및 그 방법' 과 특허출원번호 1020020019636호 '절연된 금속회전몸체 및 자속밀도 집중체를 이용한 금속섬유의 제조장치 및 그 방법'을 이용하여 금속섬유를 생산하는 것이 바람직하며, 그 밖의 방법을 이용하여도 무방하다.On the other hand, as a method of producing a metal fiber as described above Patent Application No. 1020020019635 filed by the applicant of the present invention 'Insulated metal rotating body and a manufacturing apparatus and method of the metal fiber using the same' and Patent Application No. 1020020019636 'Insulation It is preferable to produce a metal fiber using the metal rotating body and the apparatus for producing a metal fiber using the magnetic flux density concentrator and the method thereof, and other methods may be used.
이 생산단계(100)를 거친 금속섬유를 일정길이(수㎛ ~ 수십㎛)로 컷팅하는 컷팅단계(120)를 거치게 되는데, 이는 일정 직경으로 형성된 금속섬유를 미세한 크기로 컷팅(Cutting)함으로서, 후술할 혼합단계(140)에서 혼합되는 수지시료와의 혼련(混練) 중에 금속섬유가 용융된 수지시료내에 편중됨 없이 균형되게 골고루 배치되도록 하기 위한 것이다.This is a cutting step 120 for cutting the metal fiber passed through the production step 100 to a predetermined length (several to several tens of micrometers), which is cut by cutting the metal fiber formed in a predetermined diameter to a fine size (cutting), will be described later In order to ensure that the metal fibers are evenly balanced evenly without being biased in the molten resin sample during kneading with the resin sample mixed in the mixing step 140.
또한, 작은 직경과 작은 길이를 갖는 금속섬유를 사용하게 되면, 후술할 성형단계(160)를 통한 성형가공시 가공성이 우수하게 되고, 성형된 제조품의 외관이 미려하게 된다.In addition, when using a metal fiber having a small diameter and a small length, it is excellent in workability during the molding process through the forming step 160 to be described later, the appearance of the molded article is beautiful.
이 컷팅단계(120)를 거친 금속섬유와 수지시료를 혼합한 후, 혼련(混練)하는 혼합단계(140)를 거치게 되는데, 이는 후술할 성형단계(160)를 거쳐서 성형가공되는 제조품의 사용 용도에 따라 금속섬유의 혼합비율을 조정함으로서, 제조품의 강성(剛性)을 조절하게 되고, 마그네슘 또는 알루미늄 재질로 된 금속섬유의 혼합비율을 조정하여 성형단계(160)를 거쳐서 성형가공되는 제조품이 마그네슘 또는 알루미늄 사출품과 유사한 성질을 갖게 할 수 있다.After mixing the metal fiber and the resin sample through the cutting step 120, and then kneading (kneading) through a mixing step 140, which is used for the use of the manufactured product molded through the forming step 160 to be described later By adjusting the mixing ratio of the metal fiber according to the control, the rigidity of the manufactured product is adjusted, and the mixing ratio of the metal fiber made of magnesium or aluminum is adjusted to form the manufactured product through the forming step 160 to magnesium or aluminum. It can have similar properties as the injection molded product.
이 혼합단계(140)를 거쳐서 생성된 금속섬유를 함유한 수지를 사출성형하여 제조품을 생산하는 성형단계(160)를 거침으로서, 금속섬유가 함유한 수지를 이용한 제조품이 완성되는데, 이 제조품은 생산단계(100)에서 이미 생산되는 금속섬유의 직경 즉, 초정밀 제품에 사용시 1~10미크론(㎛), 정밀 제품에 사용시 11~50미크론(㎛), 일반 제품에 사용시 51~150미크론(㎛) 범위에 따라 고강성의 구조재료나, 컴퓨터 및 휴대폰 등의 전자파 차단을 위한 케이싱 및 전자파에 영향을 크게 받는 초정밀 전자회로의 전자파 차단 케이싱 등으로 생산되어 진다.Through the molding step 160 of injection molding the resin containing the metal fiber produced through the mixing step 140 to produce a manufactured product, the manufactured product using the resin containing the metal fiber is completed, and the manufactured product is produced. The diameter of the metal fibers already produced in step 100, that is, 1 to 10 microns (μm) for use in ultra-precision products, 11 to 50 microns (μm) for precision products, and 51 to 150 microns (μm) for general products As a result, it is produced as a highly rigid structural material, a casing for blocking electromagnetic waves of computers and mobile phones, and an electromagnetic shielding casing for ultra-precision electronic circuits greatly affected by electromagnetic waves.
그러므로, 전자파 차단을 위한 별도의 부재가 필요없게 되고, 그로 인해 제품의 무게 및 부피가 감소하게 된다.Therefore, there is no need for a separate member for blocking the electromagnetic waves, thereby reducing the weight and volume of the product.
또한, 금속섬유가 함유된 수지로 성형된 제품은 경량이면서도, 고강성의 성질을 갖게 되어 선박, 항공기 등의 구조재에 사용할 수 있게 된다.In addition, a product molded of a resin containing a metal fiber has a lightweight and high rigidity properties can be used in structural materials such as ships, aircraft.
