Description

수용성 폴리우레탄이 코팅된 폴리우레탄 장갑의 건식 제조방법{Dry manufacturing method for polyurethane gloves coated by water soluble polyurethane}Dry manufacturing method for polyurethane gloves coated by water soluble polyurethane

본 발명은 산업용, 또는 농업용 및 가정용으로 널리 사용되고 있는 폴리우레탄 장갑의 제조에 있어서 산업폐수의 발생을 방지하고, 또한 장갑의 표면에 미세한 기공과 거친표면을 형성할 수 있는 수용성 폴리우레탄이 코팅된 폴리우레탄 장갑의 건식 제조방법에 관한 것이다.The present invention is a polycarbonate coated with a water-soluble polyurethane that prevents the generation of industrial wastewater in the manufacture of polyurethane gloves widely used for industrial, agricultural, and household purposes, and also forms fine pores and rough surfaces on the surface of the gloves. It relates to a dry manufacturing method of urethane gloves.

일반적으로, 폴리우레탄 장갑은 내구성과 우수한 착용감으로 산업용과 가정용으로 널리 활용되고 있는 장갑이다. 이러한 장갑을 제조하는 방법으로 종래의 방법은 습식폴리우레탄 제조방법이 있다.In general, polyurethane gloves are gloves that are widely used for industrial and home use because of durability and excellent fit. As a method of manufacturing such gloves, a conventional method is a wet polyurethane production method.

그러나, 종래의 습식 제조방법은 폴리우레탄수지에 유화제와 표백용토너를 혼합한 용액에 폴리에틸렌사로 제조된 장갑을 함침하여 코팅함으로써 제조된다. 이때 코팅된 장갑은 약 10oC 이하의 냉각수에 15분, 그리고 온수(50-60oC)에 15분 함침하여 용제의 제거작업 및 폴리우레탄의 고형화작업을 진행하게 된다.However, the conventional wet manufacturing method is prepared by impregnating and coating a glove made of polyethylene yarn in a solution in which an emulsifier and a bleach toner are mixed in a polyurethane resin. In this case, the coated gloves are impregnated with cooling water of about 10 o C or less for 15 minutes and hot water (50-60 o C) for 15 minutes to remove the solvent and solidify the polyurethane.

이와 같이 종래의 습식폴리우레탄 장갑의 제조방식은 고형화작업을 피할 수 없게 되고, 따라서 폐수의 발생으로 인한 환경오염을 유발하게 되는 단점이 있다.As such, the manufacturing method of the conventional wet polyurethane gloves cannot avoid the solidification operation, and thus has the disadvantage of causing environmental pollution due to the generation of waste water.

이러한 단점을 개선하고자 또 다른 습식폴리우레탄 장갑의 제조방법이 개발되었다. 국내특허 293055호(출원번호:1998-031815 출원일:1998년 08월 03일), "습식폴리우레탄 장갑 및 그 제조방법"이 환경오염을 방지하기 위하여 개발된 제조방식이나, 이 방법도 냉각수와 온수를 이용한 폴리우레탄의 고형화 작업이 포함되므로 환경폐수의 발생이 필연적임을 알 수 있다. 종래의 단점을 개선하기 위하여 개발된 이러한 방법도 발포촉진 유화제(상품명: s-153) 130-150 중량%에 폴리우레탄 수지(100중량%), 항변제를 교반시킨 용액을 코팅하여 장갑을 제조한 뒤 냉각수에 15분, 온수에 15분 함침하여 발포촉진유화제를 제거시킴으로 환경폐수가 발생한다는 것을 명확히 알 수 있다. 또한 습식폴리우레탄 제조방법으로 제조될 경우 미세한 기공이 형성된다고 하였으나, 실제 습식폴리우레탄 제조방법으로 제조되어 시판되고 있는 장갑의 확대사진을 볼 경우 미세한 기공은 확인되지 않았다(fig 1참조). 다만 표면의 매끄러움으로 인하여 장갑의 미끄럼 방지가 현저히 떨어질 것으로 예상되었다.In order to remedy this drawback, another wet polyurethane gloves manufacturing method has been developed. Korean Patent No. 293055 (Application No .: 1998-031815 Filed Date: Aug. 03, 1998), "Wet Polyurethane Gloves and Manufacturing Method thereof" is a manufacturing method developed to prevent environmental pollution, but this method is also used for cooling water and hot water It can be seen that the generation of environmental wastewater is inevitable because it involves the solidification of polyurethane using. This method was also developed to improve the disadvantages of conventional foaming emulsifiers (trade name: s-153) 130-150% by weight of polyurethane resin (100% by weight) and a solution of agitation was prepared by coating a glove It can be clearly seen that environmental wastewater is generated by removing the foaming emulsifier by impregnating the cooling water for 15 minutes and the hot water for 15 minutes. In addition, fine pores were formed when manufactured by the method of manufacturing a wet polyurethane, but when the enlarged photograph of the glove commercially manufactured and manufactured by the method of manufacturing a wet polyurethane was observed, fine pores were not confirmed (see fig 1). However, the smoothness of the surface was expected to significantly reduce the slippage of the gloves.

<fig 1><fig 1>

이와같이, 종래의 폴리우레탄 제조방법과 이의 단점을 개선하기 위하여 개발된 습식폴리우레탄 제조방법은 폐수발생이 필연적이며, 공정이 복잡하고, 고형화 및 용제 제거작업으로 인하여 제조시간이 길어지는 문제점이 있다.As such, the conventional polyurethane production method and the wet polyurethane production method developed to improve the disadvantages thereof inevitably generate waste water, have a complicated process, and have a long manufacturing time due to solidification and solvent removal.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출한 것으로서, 산업용, 또는 농업용 및 가정용으로 널리 사용되고 있는 폴리우레탄 장갑의 제조에 있어서 종래의 습식방법을 지양하고 건식방법을 발명함으로써 산업폐수가 발생하지 않으며, 장갑의 표면에 미세한 기공(pore)을 주어 투습성과 통기성을 우수하게 하고, 거친표면을 형성하여 미끄럼방지가 현저히 좋아지도록 한 수용성 폴리우레탄이 코팅된 폴리우레탄 장갑의 건식 제조방법을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, in the manufacture of polyurethane gloves that are widely used for industrial, agricultural, and household use, avoiding the conventional wet method and inventing the dry method does not generate industrial wastewater To provide a dry manufacturing method of a polyurethane gloves coated with a water-soluble polyurethane to give a fine pore (pore) on the surface of the glove to excellent moisture permeability and breathability, and to form a rough surface to significantly improve the slip resistance. There is this.

상기 목적은 본 발명에 따라, 폐수발생을 방지하기 위하여 냉수와 온수에 함침하는 공정을 삭제할 필요가 있으며, 이 경우 수용성 폴리우레탄을 이용하면 가능하다는 것을 다년간의 연구 끝에 개발하게 되었다. 그러나 건식공정에서는 수용성폴리우레탄의 고형화 및 용제의 제거작업이 냉수와 온수를 사용하지 않고 열로써 건조하므로 이때 온도의 선택은 최종 장갑의 물성과 표면구조에 상당한 영향이 있음을 알게 되었다. 또한 수용성 폴리우레탄의 농도는 최종장갑의 미세한 기공의 크기에도 영향이 있다는 것을 다년간의 연구결과로 밝혀졌다. 따라서 본 발명의 기술적 과제는 산업용, 또는 농업용 및 가정용으로 널리 사용되고 있는 폴리우레탄 장갑의 제조에 있어서 종래의 습식방법을 지양하고 건식방법을 발명함으로써 산업폐수를 발생하지 않으며, 장갑의 표면에 미세한 기공을 주어 투습성과 통기성을 우수하게 하고, 표면을 거칠게 형성하여 미끄럼방지가 현저히 좋아지도록 건식공정을 개발하는 데에 있다. 상기와 같은 목적을 달성하기 위하여 수용성 폴리우레탄 수지 100 중량%에 소량의 물과 용제(Methylethylketone, MEK)를 혼합하여 용액을 제조한 후 폴리에틸렌사 또는 그 외의 섬유로 제조된 장갑을 함침하면 폴리우레탄이 코팅된 장갑이 일차 제조된다. 코팅된 장갑은 40-60oC의 건조실에서 약 10-30분 정도 건조시키면 용제가 증발되고 우레탄 도막이 형성된다. 이때 우레탄 도막은 막힌 기공을 형성하여 거칠은 표면을 제공하게 된다. 그 다음 2차 건조실(100-150oC)에서 약 20-40분 정도 건조되면 장갑에 남아있던 물과 1차 건조에서 남아있던 용제가 함께 증발하면서 미세한 기공(열린기공)을 장갑의 표면에 발생시키게 된다. 이때 MEK와 물의 량(또는 수용성 폴리우레탄의 농도) 및 건조시간에 따라 미세한 기공의 크기차이를 조절할 수 있는 것이 본 발명의 특징이며, 습식폴리우레탄 제조공법과 달리냉수와 온수공정을 제거하여 공정이 간편하고, 제조시간도 단축되는 효과도 있다. 특히 폐수는 전혀 발생하지 않으면서 종래의 장갑과 동일한 물성을 보여주며(표 1참조), 표면의 구조에서는 열린기공과 거친 표면(닫힌 기공, 그림 2참조)을 동시에 갖고 있는 독특한 구조로써 종래의 장갑보다 더 우수한 구조를 가질 수 있다는 장점이 있다.According to the present invention, in order to prevent the generation of waste water, it is necessary to eliminate the process of impregnating cold water and hot water, in which case it has been developed after many years of research that it is possible to use a water-soluble polyurethane. However, in the dry process, since the solidification of the water-soluble polyurethane and the removal of the solvent are dried by heat instead of using cold water and hot water, it was found that the temperature selection had a significant effect on the physical properties and surface structure of the final glove. Many years of research have shown that the concentration of water-soluble polyurethane also affects the size of the fine pores of the final gloves. Therefore, the technical problem of the present invention is to avoid the conventional wet method and invent the dry method in the manufacture of polyurethane gloves which are widely used for industrial, agricultural, and household purposes, and does not generate industrial wastewater, and fine pores are formed on the surface of the gloves. It is to develop a dry process so that the moisture permeability and breathability are excellent, and the surface is roughened to improve the slip resistance. In order to achieve the above object, a small amount of water and a solvent (Methylethylketone, MEK) are mixed with 100% by weight of a water-soluble polyurethane resin to prepare a solution, and then impregnated with gloves made of polyethylene yarn or other fibers. Coated gloves are made first. The coated gloves are dried in a drying chamber at 40-60 o C for about 10-30 minutes to evaporate the solvent and form a urethane coating. At this time, the urethane coating film forms clogged pores to provide a rough surface. After about 20-40 minutes of drying in the secondary drying chamber (100-150 o C), the water remaining in the glove and the solvent remaining in the first drying evaporate together, creating fine pores (open pores) on the surface of the glove. Let's go. At this time, it is a feature of the present invention to control the size difference of the fine pores according to the amount of MEK and water (or the concentration of water-soluble polyurethane) and drying time, and unlike the wet polyurethane manufacturing method, the process by removing the cold water and hot water process It is also simple, and the manufacturing time is also shortened. In particular, the waste water does not occur at all and exhibits the same physical properties as conventional gloves (see Table 1). The surface structure is a unique structure having both open pores and rough surfaces (closed pores, see Fig. 2). There is an advantage that it can have a better structure than.

도 1은 본 발명인 수용성 폴리우레탄이 코팅된 폴리우레탄 장갑의 건식 제조방법에 관한 공정도이다.1 is a process chart for the dry manufacturing method of the polyurethane gloves coated water-soluble polyurethane of the present invention.

이하, 첨부한 도면을 참조하여 본 발명인 수용성 폴리우레탄이 코팅된 폴리우레탄 장갑의 건식 제조방법에 관해 좀더 상세하게 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in more detail with respect to the dry manufacturing method of the water-soluble polyurethane-coated polyurethane gloves of the present invention.

본 발명의 수용성 폴리우레탄이 코팅된 폴리우레탄 장갑의 건식 제조방법에 따르면 수용성폴리우레탄 수지와 물, 그리고 수용성 용제(MEK)의 혼합액(M101)에 폴리에틸렌사, 또는 그 외의 섬유로 직조된 장갑을 함침하여 코팅(M102)한 후 건조실에서 건조(M103,M104)시키면 거칠은 표면과 미세한 기공을 동시에 형성하는 장갑이 제조되게 된다. 이때 수용성폴리우레탄의 농도(물과 MEK의 중량)의 조절로써 도막의 미세한 기공구조를 조절할 수 있으며, 건조실에서의 온도와 시간의 조절로써 거친 표면의 구조를 발생시킬 수 있다. 상기와 같은 건식 제조방법은 냉수와 온수 공정이 제거되어 폐수발생이 없으며, 공정의 간단화로 인하여 제조시간이 절약되고, 따라서 장갑의 제조단가도 저감시키는 장점이 있다. 본 발명의 실시예는 다음과 같다.According to the dry manufacturing method of the polyurethane gloves coated with a water-soluble polyurethane of the present invention, the mixed solution (M101) of a water-soluble polyurethane resin, water, and a water-soluble solvent (MEK) is impregnated with a glove made of polyethylene yarn or other fibers. After the coating (M102) and dried in the drying chamber (M103, M104) to produce a glove to form a rough surface and fine pores at the same time. At this time, the fine pore structure of the coating film can be controlled by controlling the concentration of water-soluble polyurethane (weight of water and MEK), and a rough surface structure can be generated by controlling temperature and time in a drying chamber. The dry manufacturing method as described above has the advantage that the cold water and hot water processes are removed, there is no waste water generation, and the manufacturing time is saved due to the simplification of the process, thus reducing the manufacturing cost of the gloves. Embodiments of the present invention are as follows.

[실시예 1] 100중량%의 수용성폴리우레탄 수지에 50-60중량%의 물과 100-200중량%의 MEK, 50-100중량%의 토너(Toner)를 혼합하여 교반시킨 다음 직조된 장갑을 손 모양의 금형에 끼운 후 디핑(Deeping)처리하여 코팅한 다음 40-60oC의 건조실에서 10-30분 1차 건조시키면 용제가 증발하면서 도막이 거칠은 표면으로 형성된다. 그 다음 100-150oC의 건조실에서 20-40분 동안 2차 건조시키면 물과 남아있던 용제가 함께 증발하면서 도막에 미세한 기공이 형성되게 된다. 이 과정을 거치면 투습성과 통기성이 있으며 방수성이 있는 폴리우레탄 장갑이 제조되게 된다.[Example 1] 50-60% by weight of water, 100-200% by weight of MEK, 50-100% by weight of toner was mixed with 100% by weight of water-soluble polyurethane resin, and then woven gloves After inserting into a hand-shaped mold and coating by dipping, it is first dried for 10-30 minutes in a drying chamber at 40-60 o C. The solvent evaporates to form a rough surface. Second drying in a drying chamber at 100-150 o C for 20-40 minutes causes the water and the remaining solvent to evaporate together, forming fine pores in the coating. This process produces breathable, breathable and waterproof polyurethane gloves.

[실시예 2] 100중량%의 수용성폴리우레탄 수지에 50-100중량%의 유화제와 100-200중량%의 MEK, 50-100중량%의 토너(Toner), 10-50중량%의 HP-2000을 혼합하여 교반시킨 다음 직조된 장갑을 손 모양의 금형에 끼운 후 디핑(Deeping)처리하여 코팅한 다음 40-60oC의 건조실에서 10-30분 1차 건조시키면 용제가 증발하면서 도막이 거칠은 표면으로 형성된다. 그 다음 100-150oC의 건조실에서 20-40분 동안 2차건조시키면 물과 남아있던 용제가 함께 증발하면서 도막에 미세한 기공이 형성되게 된다. 이때 미세한 기공의 크기는 실시예 1보다 작게 된다. 이 과정을 거치면 투습성과 통기성이 있으며 방수성이 있는 폴리우레탄 장갑이 제조되게 된다. 제조된 장갑은 전자산업의 산업용으로 활용된다.Example 2 50-100 wt% emulsifier, 100-200 wt% MEK, 50-100 wt% Toner, 10-50 wt% HP-2000 in 100 wt% water-soluble polyurethane resin After mixing and stirring, put the woven glove into a hand-shaped mold, apply coating by dipping, and then dry it first in a drying chamber at 40-60 o C for 10-30 minutes. Is formed. Then, secondary drying for 20-40 minutes in a drying chamber at 100-150 o C causes the water and the remaining solvent to evaporate together, forming fine pores in the coating. At this time, the size of the fine pores is smaller than in Example 1. This process produces breathable, breathable and waterproof polyurethane gloves. The manufactured gloves are used for the industrial use of the electronics industry.

[실시예 3] 100중량%의 수용성폴리우레탄 수지에 50-60중량%의 물과 100-200중량%의 MEK, 50-100중량%의 토너(Toner), 10-50중량%의 HP-2000, 10-50중량%의 HN-100을 혼합하여 교반시킨 다음 직조된 장갑을 손 모양의 금형에 끼운 후 디핑(Deeping)처리하여 코팅한 다음 80-100oC의 건조실에서 10-30분 1차 건조시키면 용제가 증발하면서 도막이 거칠은 표면으로 형성된다. 그 다음 100-150oC의 건조실에서 20-40분 동안 2차 건조시키면 1차 건조에서 남아있던 물이 증발하면서 최종적인 폴리우레탄 장갑이 제조되게 된다. 이 과정을 거치면 도막에 미세한 기공이 형성되지 않으며, 따라서 장갑은 과수용이나 낙농용 등의 농업용으로 사용하게된다.Example 3 50-60 wt% water, 100-200 wt% MEK, 50-100 wt% Toner, 10-50 wt% HP-2000 in 100 wt% water-soluble polyurethane resin , 10-50% by weight of HN-100 was mixed and agitated, and then woven gloves were put in a hand-shaped mold and then coated by dipping (Deeping), followed by 10-30 minutes in a drying chamber at 80-100 o C. When dried, the solvent evaporates to form a rough surface. Second drying for 20-40 minutes in a drying chamber at 100-150 o C then evaporates the water remaining in the first drying to produce the final polyurethane glove. After this process, fine pores are not formed in the coating film, and thus, gloves are used for agriculture such as over-water or dairy.

[실시예 4] 100중량%의 수용성폴리우레탄 수지에 50-60중량%의 물과 100-200중량%의 MEK, 50-100중량%의 토너(Toner), 50-100중량%의 HP-2000, 1-5중량%의 가교제를 혼합하여 교반시킨 다음 직조된 장갑을 손 모양의 금형에 끼운 후 디핑(Deeping)처리하여 코팅한 다음 80-100oC의 건조실에서 10-30분 1차 건조시키면 용제가 증발하면서 도막이 형성된다. 이때의 도막은 가교제의 영향으로 표면의 접착력이 향상되게 된다. 그 다음 100-150oC의 건조실에서 20-40분 동안 2차 건조시키면 1차 건조에서 남아있던 물이 증발하면서 도막에 미세한 기공을 형성하며 최종적인 폴리우레탄 장갑이 제조되게 된다. 상기와 같은 제조방법으로 제조된 장갑은 실시예 1보다 표면은 부드러우나 접착력이 우수하게 되어 전자산업의 산업용으로 사용하게된다.Example 4 50-60 wt% water, 100-200 wt% MEK, 50-100 wt% Toner, 50-100 wt% HP-2000 in 100 wt% water-soluble polyurethane resin , 1-5% by weight of the crosslinking agent was mixed and stirred, and then woven gloves were put in a hand-shaped mold, then coated by dipping (Deeping), and then first dried in a drying chamber at 80-100 o C for 10-30 minutes. As the solvent evaporates, a coating film is formed. The coating film at this time is to improve the adhesion of the surface under the influence of the crosslinking agent. Second drying for 20-40 minutes in a drying chamber at 100-150 o C then evaporates the water remaining in the first drying, forming fine pores in the coating and producing the final polyurethane glove. Glove manufactured by the manufacturing method as described above is smoother than the surface of Example 1, but the adhesive strength is excellent to be used in the industry of the electronic industry.
