Description

이온빔조사에 의한 대전방지용 진공성형용기 제조방법{Manufacturing process for anti-static vacuum forming instrument by irradiation of ion beam} Manufacturing process for anti-static vacuum forming instrument by irradiation of ion beam

본 발명은 이온빔조사에 의한 대전방지용 진공성형용기 제조방법에 관한 것으로, 자세하게는 폴리프로필렌 수지 조성물을 진공 성형하여 만든 용기에 이온빔을 조사하여 대전방지성질을 갖도록 하는 것을 특징으로 하는 대전방지용 진공성형용기 제조방법에 관한 것이다. The present invention relates to a method for manufacturing an antistatic vacuum forming container by ion beam irradiation, and in detail, to an antistatic vacuum forming container, which has an antistatic property by irradiating an ion beam to a container made by vacuum molding a polypropylene resin composition. It relates to a manufacturing method.

종래의 진공성형용기는 다양성, 편리성, 견고성, 경제성을 갖고 있음에도 불구하고, 대전방지 기능이 없어 단순하게 일반 물품을 담아 운반 및 보관하는데 사용하였다. 따라서 정전방지를 필요로 하는 전자 부품, 반도체 등 고부가가치 물건의 운반 및 보관은 다른 운송수단을 이용하였다. Conventional vacuum forming container has a variety, convenience, robustness, economical, but there is no antistatic function was used to simply carry and store the general goods. Therefore, the transportation and storage of high value-added objects such as electronic components, semiconductors, etc., which require antistatic protection, have used other means of transportation.

종래의 대전방지 용기는 대전방지제 첨가법과 전도성고분자재료를 사용하는 두가지 방법에 의해 제조되었다. Conventional antistatic containers have been produced by two methods using an antistatic agent addition method and a conductive polymer material.

대전방지제 첨가법은 분자내 친수기와 친유기를 동시에 가지고 있는 대전방지제를 용기 표면에 흡착하여 친수성 부분을 용기표면에 배열시킴으로써 공기 중의 수분을 흡수하게 하여 이 수분과 대전방지제 자신의 전도성에 의해 용기에 발생한 정전기를 방전시키는 것이다. 이 경우, 상대 습도 40% 이하에서 대전방지 성능이 저하되고, 대전방지제의 불균일성 때문에 물세척이나 닦아내기에 의해 부분적으로 대전방지효과가 장기간 지속되지 않으며, 대전방지제 내부에 포함된 독성물질에 대한 주의가 필요한 것이 단점이다. The antistatic agent adds an antistatic agent having both a hydrophilic group and a lipophilic group to the surface of the container, and arranges the hydrophilic part on the surface of the container to absorb moisture in the air. It is to discharge static electricity. In this case, the antistatic performance is lowered at a relative humidity of 40% or less, and the antistatic effect is not sustained for a long time by washing or wiping off the water due to the nonuniformity of the antistatic agent, and attention is paid to toxic substances contained in the antistatic agent. What is needed is a disadvantage.

전도성 고분자재료를 이용한 용기의 경우, 공액 이중결합을 갖는 Polyaniline, Polypyrrole, Polythiophene 등 전기전도특성을 갖는 고분자재료를 사용한다. 전도성 고분자는 산화안정성이 나쁘고 기계적 물성이 낮아 고분자 사슬에 존재하는 분자간의 인력으로 인한 불용성 때문에 가공성이 취약한 단점이 있다.In the case of a container using a conductive polymer material, a polymer material having electrical conductivity such as polyaniline, polypyrrole, or polythiophene having a conjugated double bond is used. Conductive polymers have a disadvantage of poor processing stability due to poor oxidation stability and low mechanical properties due to insolubility due to intermolecular attraction in the polymer chain.

상기와 같은 문제점을 해결하기 위한 본 발명의 목적은 정전기방지를 필요로 하는 전자 부품, 반도체 등 고부가가치 물건의 운송 및 보관에 종래의 진공성형용기를 쉽게 사용할 수 있도록 하기 위해 대전방지 기능이 첨가된 진공성형용기를 제조하는 방법을 제공하는데 있다. An object of the present invention for solving the above problems is that an antistatic function is added to make it easy to use a conventional vacuum molding container for transportation and storage of high value-added objects such as electronic components, semiconductors that need antistatic The present invention provides a method for manufacturing a vacuum molding container.

상기와 같은 본 발명의 목적은 폴리프로필렌 수지 조성물을 진공 성형하여 만든 용기에 이온빔을 가속 후 조사시켜 이온이 주입된 대전방지용 진공성형용기를 제조하는 방법을 제공함으로써 달성된다.The object of the present invention as described above is achieved by providing a method for producing an antistatic vacuum forming container in which ions are implanted by accelerating and irradiating an ion beam to a container made by vacuum molding a polypropylene resin composition.

상기한 바와 같은 목적을 달성하고 종래의 결점을 제거하기 위한 과제를 수행하는 본 발명의 실시예인 구성과 그 작용을 첨부도면에 연계시켜 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings, the configuration and the operation of the embodiment of the present invention to achieve the object as described above and to perform the task for eliminating the conventional drawbacks.

도 2는 본 발명의 대전방지용 진공성형용기 제조 공정도인데, 공정은 폴리프로필렌수지물을 투입하는 단계와, 이를 가열하는 단계와, 가열되어 용융된 수지를 진공성형하는 단계와, 성형물을 냉각하는 단계와, 냉각 후 트리밍하는 단계와, 마지막으로 이온조사하는 단계로 이루어진다.Figure 2 is a manufacturing process diagram of the antistatic vacuum forming container of the present invention, the process is a step of adding a polypropylene resin, heating it, vacuum forming the heated molten resin, and cooling the molding And trimming after cooling, and finally ion irradiation.

도 3은 본 발명의 개략적인 이온빔 조사장치 구성에 대한 실시예도를 도시하고 있는데, 그 공정 및 구성을 살펴보면, 폴리프로필렌 수지 조성물로 제조된 진공성형용기(1)를 진공챔버(2)내의 지지구조(3)에 부착시킨 후, 지지구조물을 천천히 이동시킨다. Figure 3 shows an embodiment of the schematic configuration of the ion beam irradiation apparatus of the present invention. Looking at the process and configuration, the support structure in the vacuum chamber (2) of the vacuum forming vessel (1) made of a polypropylene resin composition After attaching to (3), slowly move the support structure.

상기 이동형 지지구조물 상단부에 이온원(4)을 한 개 이상 설치한다. At least one ion source 4 is installed at the upper end of the movable support structure.

상기 지지구조(3) 형상은 보관 및 운송 제품의 용도 및 모양에 따라 결정되는데 주로 진공성형용기 표면에 이온빔 조사를 균일하고 쉽게 할 수 있도록 다양한 형태로 제작할 수 있다. The shape of the support structure (3) is determined according to the use and shape of the storage and transportation products, and can be manufactured in various forms to make the ion beam irradiation uniformly and easily on the surface of the vacuum molding container.

다양한 형태를 갖는 진공성형용기 표면에 이온빔을 보다 균일하게 조사하기 위해 이동과 회전이 자유로운 자동화된 범용 다축 지지구조를 사용한다.In order to more uniformly irradiate the ion beam onto the surface of the vacuum forming container having various shapes, an automated general-purpose multi-axis support structure is used that is free to move and rotate.

설치된 이온원으로부터 인출된 이온빔(5)을 가속 후 용기에 조사한다. 이온 빔 가속시의 조건은 진공도 1×10-5torr에서 이온빔 세기 40keV ~ 50keV, 이온 조사량 3×1016 ions/cm2 이상의 조건으로 조사하여 주입한다.The ion beam 5 drawn out from the installed ion source is accelerated and irradiated to the container. The conditions for the ion beam acceleration are irradiated under the conditions of the ion beam intensity of 40 keV to 50 keV and the ion irradiation amount of 3 x 10 16 ions / cm 2 or more at a vacuum degree of 1 x 10 -5 torr.

이온조사 시 고려해야할 사항은 이온빔의 에너지와 전류, 조사 방향, 지지구조의 이동속도이다. 즉, 이들 값은 적용하고자 하는 진공성형용기의 크기 및 모양에 따라 실험적으로 결정된다. 진공챔버 내의 진공도는 10-5 Torr 이하를 유지한다.Considerations for ion irradiation include the energy and current of the ion beam, the direction of irradiation, and the speed of movement of the support structure. That is, these values are determined experimentally depending on the size and shape of the vacuum forming container to be applied. The degree of vacuum in the vacuum chamber is kept below 10 -5 Torr.

진공성형용기 표면에 조사된 이온빔은 용기 표면의 전기저항을 감소시켜 결과적으로 용기표면에 도전성을 갖게 하여 전자부품과의 접촉 시 발생하는 정전기를 방지한다. The ion beam irradiated on the surface of the vacuum molding container reduces the electrical resistance of the surface of the container and consequently makes the surface of the container conductive, thereby preventing static electricity generated when contacting electronic components.

본 발명의 이온빔 조사에 의해 만들어진 진공성형용기는 표면저항이 1011Ω/sq 이하로서 정전분산에 의해 정전기가 발생하지 않고, 또한 이온빔 조사 전의 진공성형용기와 동일한 성능 및 외관과 대전방지 기능을 갖는다.The vacuum forming vessel made by the ion beam irradiation of the present invention has a surface resistance of 10 11 Ω / sq or less, which does not generate static electricity by electrostatic dispersion, and has the same performance, appearance, and antistatic function as the vacuum forming vessel before ion beam irradiation. .

본 발명은 기존의 폴리프로필렌 수지 조성물을 진공 성형하여 만든 용기에 쉽게 적용할 수 있음에 따라 용기의 가용성을 높일 수 있고, 보관 및 운송 제품 특성에 적합한 대전방지용 용기를 다양하게 제작할 수 있어 용기의 선택성과 효용성이 증가한다. The present invention can be easily applied to a container made by vacuum molding an existing polypropylene resin composition to increase the solubility of the container, and to produce a variety of antistatic containers suitable for storage and transportation product characteristics, the selection of the container Performance and utility increase.

대전방지 첨가제를 사용하지 않음으로써 인체에 무해하고, 환경 친화적인 대전방지용기를 제조할 수 있다. By not using an antistatic additive, it is possible to manufacture an antistatic container which is harmless to a human body and is environmentally friendly.

대전방지기능을 갖는 진공성형용기를 제조할 수 있게 됨으로써, 정전기방지를 필요로 하는 전자 부품, 반도체 등 고부가가치 물품을 편리하고 안전하게 운반할 수 있다.By being able to manufacture a vacuum forming container having an antistatic function, it is possible to conveniently and safely transport high value-added articles such as electronic components and semiconductors that require antistatic properties.
