Dust of paper particles generated from filter paper in the filter paper, hot melt resin lattice pattern that has a gas passing function during sterilization and sterilization of medical devices, and an impact protection function when transporting and handling a package where medical devices are refrigerated. It relates to a method for producing a coated filter paper.
종래 이와 같은 목적으로 사용되는 여러 형태의 무늬가 형성된 필터지의 제조방법은 PVC, 폴리에치렌 등의 합성수지를 유기용매에 용해시킨 용액으로 필터지 위에 여러 형태의 무늬를 코팅하거나 인쇄하여 형성시킴으로써 제조공정에서 발생하는 용매의 유독가스로 인체에 유해하며 화재발생 등의 문제점과 포장대를 구성하는 필터지에 인쇄 또는 코팅된 합성수지 무늬로부터 잔존용매가 침출되어 의료기구에 첨착될 수 있고 특히 주사기, 클립 등 합성수지재의 의료기구는 침출용매로 침식되어 손상될 수 있는 문제점을 야기시키고 있다.Conventionally, a method of manufacturing a filter paper having various shapes of patterns used for this purpose is a solution in which synthetic resins such as PVC and polyethylene are dissolved in an organic solvent, thereby forming the coating process by coating or printing various types of patterns on the filter paper. It is harmful to the human body due to the toxic gas of the solvent generated from the solvent and the residual solvent may be leached from the synthetic resin pattern printed or coated on the filter paper constituting the packing table and attached to the medical device. Ash medical equipment is causing problems that can be damaged by erosion with a leaching solvent.
본 발명은 종래 의료기구용 포장대로 사용되는 여러 형태의 무늬가 코팅된 필터지의 문제점을 해소시킬 수 있는 온도 상승으로 연화되거나 용융상태에서 접착성을 갖게되는 핫멜트(Hot melt)형 수지를 수재료로 사용함으로써 코팅 또는 인쇄작업의 작업성이 극히 우수하고 포장대의 해체시 합성수지필름과 여과지가 실링된 주연부 부분을 쉽게 탈리할 수 있게 함으로써 종이 입자의 먼지 발생률을 더욱 줄일 수 있고 특히 용액형 수지를 사용하지 않으므로 용매에 의한 악취나 피해로부터 자유로울 수 있으며 포장된 의료기구의 오염이나 손상으로 부터 벗어날 수 있는 의료기구 포장대용의 격자무늬가 코팅이 형성된 필터지의 제조방법을 제고함에 목적이 있다 하겠다.The present invention uses a hot melt resin that is softened due to a temperature rise that can solve the problems of various types of patterned filter papers used as a package for a conventional medical device or has adhesiveness in a molten state as a water material. This makes the coating or printing process extremely excellent and makes it possible to easily detach the periphery of the resin film and filter paper when disassembling the packaging, thereby further reducing the dust incidence of paper particles. It is an object of the present invention to improve the manufacturing method of the filter paper in which the lattice pattern coating for the medical device packaging can be free from odor or damage caused by the solvent and can escape from the contamination or damage of the packaged medical device.
도 1은 본 발명에 사용되는 코팅장치의 작동 상태도,1 is an operating state of the coating apparatus used in the present invention,
도 2는 본 발명에 의해 성형된 포장대의 사시도 이다.2 is a perspective view of a pavement molded by the present invention.
본 발명은 의료기구 포장대용 격자무늬가 형성된 필터지를 제조함에 있어서 합성수지를 유기 용해시킨 합성수지용액을 사용하지 않고 온도가 상승함에 따라 열 접착성을 나타내는 핫멜트수지(Hot melt Resin)를 주원료로 하는 소재를 사용함으로써 기존 의료기구 포장대용 필터지의 제조 및 사용상의 문제점을 해소시킨 방법으로 이를 구체적으로 설명하면 본 발명은 핫멜트 수지를 주성분으로 하는 코팅 조성물의 조성방법과 이를 이용 필터지에 코팅하는 방법으로 구성된다.The present invention provides a material mainly comprising hot melt resin (Hot melt resin) that exhibits heat adhesiveness as the temperature increases without using a synthetic resin solution in which synthetic resin is organically dissolved in preparing a filter paper having a plaid pattern for medical device packaging. The present invention will be described in detail as a method to solve the problem of the production and use of filter paper for packaging existing medical devices by using the present invention is composed of a method for the composition of the coating composition containing the hot-melt resin and a method for coating the filter paper using the same.
먼저 핫멜트 수지를 주성분으로 하는 코팅조성물의 조성은 중량비로 핫멜트수지로서 에치렌초산비닐공중합수지(EVA)35%, 파라핀왁스55%, 폴리에칠렌5%, 스치렌과 이노프렌의 공중합물4%, 산화방지제1% 를 혼합열배합통에서 온도 150-170℃로 유지된 상태에서 12시간 교반하여 코팅 조성물을 얻는다.First of all, the composition of the coating composition mainly composed of hot melt resin is a hot melt resin by weight ratio, 35% of ethylene vinyl acetate copolymer resin (EVA), paraffin wax 55%, polyethylene 5%, copolymer of styrene and inoprene 4%, oxidation 1% of the inhibitor was stirred for 12 hours while maintaining the temperature at 150-170 ° C. in the mixing heat mixer to obtain a coating composition.
다음 위에서 얻어진 코팅조성물은 여과지에 코팅하는 방법으로 도 1에서와 같이 하측에 코팅조성물수장통(1)에 코팅조성물이 채워진 상태에서 온도 150-170℃로 유지시킨 음각격자무늬(2')가 형성된 로울러(2)가 회전함으로써 로울러 표면에 코팅조성물이 첨착되고 로울러 표면에 첨착된 코팅조성물을 로울러(2)의 표면에 밀착된 나이프(3)로 제거하면 로울러(2)의 표면에 음각된 격자 무늬에만 코팅조성물이 남게되고 이 상태에서 맞물리는 가압로울러(4) 사이로 여과지(5)를 통과시키면 로울러(2)의표면에 음각된 격자 무늬에 첨착되어 있는 코팅 조성물이 여과지로 전착되어 격자 무늬가 코팅된 여과지(6)를 얻게된다.Next, the coating composition obtained above is coated with filter paper to form a negative grid pattern 2 ', which is maintained at a temperature of 150-170 ° C. in a state in which the coating composition is filled in the coating composition container 1 as shown in FIG. 1. As the roller 2 rotates, the coating composition is attached to the surface of the roller, and when the coating composition attached to the surface of the roller is removed with a knife 3 adhered to the surface of the roller 2, the lattice pattern engraved on the surface of the roller 2 is Only the coating composition remains, and in this state, passing the filter paper 5 between the interlocking pressure rollers 4 causes the coating composition attached to the lattice engraved on the surface of the roller 2 to be electrodeposited with the filter paper, thereby coating the lattice pattern. Filter paper 6 is obtained.
이상에서 핫멜트 수지로서 에치렌초산비닐공중합수지(EVA)는 폴리에치렌 보다 결정성이 낮고 초산비닐의 함유량에 따라서 연질 폴리에치롄에 닮은 성질의 것으로부터 점성이 있는 성질의 것까지 얻을 수 있고 초산비닐의 함유량은 2-40%정도이다.As described above, the ethylene vinyl acetate copolymer (EVA) as a hot melt resin has a lower crystallinity than poly ethylene and can be obtained from a material similar to that of a soft polyetchian to a viscosity property depending on the content of vinyl acetate. The vinyl content is about 2-40%.
또한 초산비닐의 함유량의 많은 것은 점성이 있는 고무탄성을 가진 상태의 성질을 나타내고 연화점은 vicat 연화점은 값으로 47-69℃의 값을 가지며 온도가 상승되어 용융점에 달하면 접착성을 나타내는 것이 특징이라 할 수 있다.In addition, the content of vinyl acetate is a characteristic of the state having a viscous rubber elasticity, the softening point of vicat softening point has a value of 47-69 ℃ as a value, and shows the adhesiveness when the temperature rises to reach the melting point Can be.
이와 같은 핫멜트수지를 본 발명의 필터지에 첨착되는 코팅조성물로 이용한 이유는 우선 용매를 사용하지 않아도 일정한 점도를 가지면서 고온에서 접착력을 갖는 특성과 의료기구 포장용 포장대 제작시 표면층의 합성수지필름과 쉽게 열융작될 수 있는 장점을 갖고 있다.The reason for using such a hot melt resin as a coating composition impregnated with the filter paper of the present invention is that it has a constant viscosity without using a solvent and has adhesive strength at a high temperature, and easily heats up the synthetic resin film of the surface layer when manufacturing a packaging table for medical device packaging. It has the advantage of being able to work.
또 코팅조성물로서 왁스의 첨가는 도 1에서와 같이 로울러(2) 표면에 음각으로 새겨진 격자무늬의 홈에 첨착된 코팅조성물을 여과지로 전착시키는 과정에서 로울러로 부터 쉽게 탈리되도록 이형성을 부여함과 동시에 로울러로 부터 쉽게 탈리되도록 이형성을 부여함과 동시에 전조성물의 점도를 조절하여 로울러로 부터 여과지로 전착과정을 쉽게 하게 하기 위한 것이다.In addition, the addition of wax as a coating composition gives release property so that the coating composition attached to the grooves of the lattice pattern engraved on the surface of the roller 2 is easily detached from the roller in the process of electrodeposition with filter paper as shown in FIG. It is to make the electrodeposition process from the roller to filter paper by controlling the viscosity of the precursor composition at the same time to give a release property so that it is easily detached from the roller.
스치렌과 이소푸렌을 공중합시킨 물질은 고무특성과 같은 탄성을 가지면서 로울로 부터 여과지로 전착되는 과정에서 여과지와 접착성을 높이며 여과지에 전착된 격자무늬가 상온에서 또는 이 이하 온도에서도 탄성을 갖게 한다.The copolymer of styrene and isoprene has the same elasticity as rubber, but it improves adhesiveness with filter paper during electrodeposition from filter to filter paper, and the lattice pattern deposited on filter paper has elasticity at or below room temperature. do.
그밖에 폴리에치렌은 포장대 완성시 여과지에 코팅된 격자무늬의 스트레스크레킹을 방지하고 고온(150-170℃)에서 전착시에 코팅되는 과정에서 로울러에 첨착된 격자무늬 조성물이 절단되거나 파손되는 일없이 여과지로 완전하게 전착되게 하는 기능성을 부여하게 된다.In addition, poly ethylene prevents the stress cracking of the lattice coated on the filter paper upon completion of the packing stand, and the lattice-attached lattice composition attached to the rollers is cut or broken in the process of coating at the time of electrodeposition at high temperature (150-170 ° C.). It imparts the functionality to be fully electrodeposited into the filter paper without.
다시 말하면 에치렌초산비닐수지(EVA)나 파라핀 왁스는 대략50-60℃에서 연화 용융되어 온도 150-170℃에서는 점도가 크게 떨어지고 분자간의 인력이 크게 떨어짐으로서 로울러에서 여과지로의 전착이 어려워지고 격자무늬의 절단과 파손이 발생하여 전착에 의한 코팅이 부분적으로 이행되므로 융점이 높은 폴리에치렌, 그리고 스치렌과 이소프렌 공중합물이 이를 보완해주게된다.In other words, ethylene vinyl acetate (EVA) or paraffin wax is softened and melted at approximately 50-60 ° C, so that the viscosity is greatly decreased at temperatures of 150-170 ° C and the intermolecular forces are greatly reduced, making electrodeposition from filter to filter paper difficult and lattice. As the cutting and breakage of the pattern occurs and the electrodeposition coating is partially carried out, the high melting point polyethylene and the styrene and isoprene copolymers compensate for this.
그밖에 항상화제는 코팅조성물 제조시 고온상태(150-170℃)로 장시간 교반함 으로써 내열성이 약한 EVA, 파라핀왁스 등의 산화 및 물성의 변질을 방지하기 위하여 소량이 첨가된다.In addition, a small amount of a stabilizer is added in order to prevent oxidation and physical property deterioration of EVA, paraffin wax and the like having low heat resistance by stirring for a long time in a high temperature state (150-170 ° C.) during the preparation of the coating composition.
이상의 코팅 조성물의 상호관계가 있어서 에치렌초산비닐공중합수지와 파라핀왁스의 사용량은 파라핀왁스를 본 발명에서 한정시킨 량이하로 사용할 경우 조성물의 점도가 커져서 로울러의 부터 여과지로 전착이 어려워지며 한정시킨 양 이상으로 증가하고 EVA수지량이 적어질 경우에 코팅 조성물의 점도가 커져서 전착이 어려워지고 격자무늬를 코팅시킨 여과지(필터지)로 포장대 제작시 합성수지필름과 열접착력이 떨어진다.The amount of ethylene vinyl acetate copolymer resin and paraffin wax used in the above-mentioned coating composition is higher than the limit of the amount of paraffin wax used in the present invention. When the amount of EVA resin decreases and the amount of EVA resin decreases, the viscosity of the coating composition increases, making electrodeposition difficult, and the lattice-coated filter paper (filter paper) is reduced to the synthetic resin film and the heat adhesive force when producing a packaging stand.
그밖에 폴리에치렌, 스치렌과 이소프렌의 공중합물 각각의 조성비는 상기 재료들의 고온에서 점도 변화가 크게 일어나지 않게 하며 전착을 용이하게 하고 폴리에치렌은 제품 완성후 여과지에 형성된 격자무늬의 스트레스크레킹, 인장력 등을 보강하고 스치렌과 이소프렌 공중합물은 코팅시나 열융착재대시 접착력을 보완하는 정도의 조성비로 적합한 량이라할 수 있다.In addition, the composition ratio of each copolymer of polyethylene, styrene and isoprene prevents the viscosity change from occurring at high temperatures of the materials and facilitates electrodeposition. The polyethylene has a stress cracking effect of lattice pattern formed on the filter paper after the completion of the product. Strengthen tensile strength and copolymer of styrene and isoprene can be said to be a suitable amount in the composition ratio to compensate for the adhesive strength during coating or heat sealant dash.
본 발명의 의한 의료기구 포장대용 격자무늬가 코팅 형성된 필터지의 제조방법은 종래 합성수지를 유기용매에 용해한 용액으로 여과지에 코팅하는 밥법과는 달리 우선 유기용매를 사용하지 않으므로 유독한 증기나 가스가 발생하지 않아 인체에 피해를 주지 않으며 의료기구를 내장시킨 포장대를 완성한 후에도 격자 무늬를 형성한 합성수지에 함유된 잔여 유기용매가 침출하여 합성수지재의 의료기구를 침식하여 의료 기구를 파손시키는 일이 없고 의료기구에 첨착되는 일이 없어 극히 위생적이라 할수 있고 탄성을 갖는 격자무늬에 의하여 포장대 내용물의 충격에 의한 파손방지의 기능도 갖게 된다.According to the present invention, a method of manufacturing a filter paper having a lattice pattern coated with a medical device for packaging according to the present invention does not use toxic vapors or gases because it does not use an organic solvent, unlike the rice method of coating a filter paper with a solution of a conventional synthetic resin dissolved in an organic solvent. It does not harm the human body, and even after completing the package with the built-in medical device, the residual organic solvent contained in the lattice-shaped synthetic resin does not leach out and damages the medical device by eroding the medical device of the synthetic resin material. It can be said to be extremely hygienic because it does not adhere, and also has a function of preventing damage caused by the impact of the contents of the package by the elastic grid pattern.
또 도 2와 같은 포장대 제작시 격자 무늬를 형성한 조성물인 에치렌초산비닐공중합체(EVA)수지는 극히 저온에서도 우수한 열접착력을 가지므로 저온에서 실링 작업이 가능한 이점을 갖고 있다.In addition, since the ethylene vinyl acetate copolymer (EVA) resin, which is a composition having a lattice pattern when manufacturing a packaging stand as shown in FIG. 2, has an excellent thermal adhesive strength even at an extremely low temperature, the sealing operation can be performed at a low temperature.
여기에서 포장대(A)는 합성수지필름(A1)과 격자무늬(A2)가 코팅되어 있는 여과지(A3)가 주연부에서 연속성의 격자무늬에 의하여 열융착 실링 되어 실링면(A4)이 형성되며 포장대 내부에는 의료기구(A5)가 내장되어 있다.Here, the packaging table (A) is a synthetic resin film (A1) and the filter paper (A3) coated with a lattice pattern (A2) is heat-sealed sealing by a continuous lattice pattern at the periphery to form a sealing surface (A4) The medical device A5 is built in.
