본 발명은 초경량 나일론 직물을 제직한 후 그 표면에 폴리우레탄 수지를 주성분으로 하는 미세다공형필름을 상기 직물의 표면에 핫멜트 라미네이팅 공정으로 코팅처리함으로써 수용성 폴리우레탄의 미세다공 필름특성과 초경량 나일론직물의 조합에 의한 결로현상방지를 위한 통기형 투습방수 소재를 제조하는 방법에 관한 것이다.The present invention relates to a process for producing an ultra lightweight nylon fabric by weaving a lightweight nylon fabric and then coating the surface of the fabric with a hot-melt laminating process on the surface of the fabric by a microporous film comprising polyurethane resin as a main component, The present invention relates to a method for manufacturing a breathable waterproofing material for airtightness for preventing condensation by combination.
최근 세계적으로 웰빙(Wellbeing) 문화에 대한 관심이 증대되면서 종래에 의류제품이 갖추어야 할 패션성과 기능성 이외에 인체에 대한 착용 쾌적감을 강조하는 특수 기능성 섬유제품에 대하여 큰 관심이 집중되고 있다.Recently, as interest in the wellbeing culture has been increasing worldwide, a great deal of attention has been focused on special functional textile products emphasizing wearing comfort in addition to fashionability and functionality that clothing products should have in the past.
특히 스포츠, 레저분야는 전 세계적인 경제성장과 더불어 가장 괄목할만한 성장을 이룬 분야중 하나이며, 스포츠·레저웨어의 성장과 함께 기능성소재의 쾌적성, 운동기능성, 패션성 등을 성취하기 위한 다각적인 연구가 진행되고 있다. 이러한 기능성들을 의류에 부여하기 위해서 업계는 여러 가지 기능성 원사를 사용하여 다양한 기능성 제품을 개발하고 있으나, 원사로부터 발현할 수 있는 기능성의 한계로 매우 제한적인 기능의 제품만을 생산하고 있는 실정이다.Especially, sports and leisure fields are one of the most remarkable growth areas along with global economic growth. It is a multifaceted research for achieving the comfort of functional materials, exercise functionality, and fashion with the growth of sports and leisure wear . In order to impart these functionalities to garments, the industry develops various functional products using various functional yarns, but it produces only limited functional products due to limitations in functionality that can be expressed from the yarn.
이러한 스포츠·레저용 섬유로부터 주로 요구되는 기능인 온도조절, 경량성, 신축성, 통기성 및 외부 환경으로부터의 보호성 등을 결합한 형태로 일부 또는 모두 발현할 수 있는 가공 기술로는 투습방수 코팅, 필름 라미네이팅 가공 등의 코팅 기술을 들 수 있으며, 특히 이와 같은 코팅 기술은 시장의 요구에 따라 코팅의 고유한 특성인 투습방수성, 방풍성, 통기성, 보온성 외에 신축성, 자외선차단성, 경량성, 부드러운 촉감 등의 기능성이 추가되어 좀 더 기능적인 면을 강조한 제품의 개발이 요구되고 있다.Processing technologies that can partially or wholly manifest the combination of temperature control, light weight, stretchability, air permeability, and protection from the outside environment, which are mainly required for sports and leisure fibers, include breathable waterproof coating, film lamination And coating technology such as this coating technology. In particular, according to the market demand, besides moisture permeability, windproofness, air permeability, and warmth, which are inherent characteristics of coating, functions such as stretchability, ultraviolet barrier property, The development of a product that emphasizes a more functional aspect is required.
현재 세계적 트렌드인 나일론 및 폴리에스테르 초박지 합섬의 염색가공에 있어서 원사 및 원단의 물리적인 특성에 기인한 가공 시의 설비에 따른 작업가능성 문제와 공정과정에서 발생하는 강도 저하 문제, 각종 견뢰도 및 원단 좌우의 색상차 등의 문제로 인해 기존의 염색가공 업체들이 많은 어려움을 겪고 있는 실정이다.In the present world trend, in the dyeing process of nylon and polyester superfine synthetic fibers, there is a possibility of workability due to the facilities at the processing due to the physical characteristics of the yarn and the fabric, strength problems caused by the process, various fastnesses, The color difference of the existing dyeing and processing companies are experiencing a lot of difficulties.
한편, 투습방수 소재는 1960년대 중반에는 수지에 염화칼슘 미세 분말을 혼입하여 원단에 코팅한 후 물에서 용출시킨 미세다공 제품이 개발되었는데, 이 제품의 투습성은 우수하나 핀 홀에 의한 누수와 한랭 시 촉감 경화, 제품의 중량감 등의 이유로 시장에 정착하지 못했다. 1970년대에 이르러 GORE-TEX가 개발되면서 투습방수소재의 기본원리가 GORE-TEX에서 제시된 PTFE 필름 라미네이팅에 의해 미세다공질 피막을 원단에 형성하는 것으로 대변되었으며, 그 후 1979년에 일본 도레이의 엔트란트가 습식공정에 의한 미다공질 피막을 갖는 코팅 제품을 시판한 후 세계 투습방수포 시장이 급속히 성장하기 시작하였다.On the other hand, in the mid-1960s, the breathable and waterproof material was coated with microcrystalline calcium chloride in a resin, coated on the fabric, and then developed into a microporous product that was eluted from water. This product has excellent moisture permeability but leaked by pinhole Hardening, and weight of the product. In the 1970s, with the development of GORE-TEX, the basic principle of breathable and waterproof materials was represented by the formation of microporous coatings on the fabric by PTFE film laminating as presented in GORE-TEX. Then, in 1979, After the market of coating products with microporous coatings by wet process, the world market of moisture permeable tarpaulins began to grow rapidly.
1980년대 초에는 후가공 기술이 아닌 특수원사를 사용하여 원단 자체의 밀도를 높인 투습방수원단이 도요보(분할형 복합섬유), 데이진(폴리에스터 극세사)에 의해 개발되었는데, 이러한 고밀도 직물은 일부 후가공 제품과 경쟁을 하였으나, 기능적인 측면에서 불리하여 이후 감성적인 측면을 강조하는 소재로 정립되었으며, 1990년대에 들어서 라미네이팅 제품과 기능성 건식코팅이 성장, 성숙기에 접어들었으며, 일본에서는 형상기억 PU 응용 제품을 소개하였다. 2000년 이후에는 세계적으로 환경규제를 강화하고 있어서 용제형 코팅, 라미네이팅 제품이 감소하고 있으며, 'Water borne type'과 TPE 필름, Hot melt 접착에 대한 연구개발이 한창 진행되어 성장하고 있으며, 'High Solid PU polymer' 코팅이 도입되었으며, 미국의 Nextec에서 실리콘 소재를 이용하여 'EPIC'이라는 제품을 개발하여 출시하고 있다. In the early 1980s, moisture-proof and waterproof fabrics were developed by using special yarns rather than post-processing technology. They were developed by Toyobo (Split Composite) and Deijin (Polyester Microfiber) In the 1990s, laminating products and functional dry coatings grew and matured. In Japan, the shape memory PU application product . Since 2000, environment-related regulations have been strengthened globally, and solvent coating and laminating products have been decreasing. Research and development on 'Water borne type', TPE film and hot melt adhesion are progressing, PU polymer 'coating, and Nextec, USA, has developed a product called' EPIC 'using silicon material.
국내에서는 1984년 코오롱의 습식 코팅 방식인 'HIPORA'를 필두로 하여 꾸준히 연구 개발되어 건식코팅과 트랜스퍼 코팅이 보급되었으며, 최근에는 라미네이팅 기술을 이용한 다양한 방식의 투습방수 원단이 개발되고 있다.In Korea, in 1984, HIPORA, which is a wet coating method of Kolon, has been researched and developed, and dry coating and transfer coating have been widely used. Recently, various types of breathable and waterproof fabrics using laminating technology have been developed.
이렇듯 투습방수 원단의 기능성은 시대의 흐름에 따라 다양하게 발전해 왔다. 개발 초기에는 주로 내수압, 투습도 등의 기본 기능을 향상시키려는 노력이 강조 되었고, 이후 보온성, 신축성 등의 신기능을 부가하는 방향이었으나 80년대 중·후반에 이르러서는 기능을 추구함과 동시에 감성에 대한 요구가 강해졌으며, 이때 기능면에서는 코팅 피막층의 결로 억제가 중요한 과제가 되어 천연 고분자 원료를 응용한 흡수 및 방수성 부여 기술이 개발 되었으며, 태양광선을 조사했을 때 축열·방열 할 수 있는 세라믹 응용기술도 도입되었다. The functionality of the breathable waterproof fabric has been developed in various ways according to the times. In the early stage of development, mainly efforts to improve basic functions such as water pressure and moisture permeability were emphasized, and then new functions such as warmth and elasticity were added. However, in the middle and late 80s, In this case, the dew condensation suppression of the coating layer is an important issue in the functional aspect. Thus, a technique of imparting absorption and water resistance using a natural polymer material has been developed, and a ceramic application technology capable of storing and radiating heat when irradiated with sunlight has also been introduced .
이러한 기존의 개발품 중 Gore-tex로 대표되는 PTFE필름의 경우 고가의 가격 및 경시변화에 따른 경화문제가 심각하고, 친수무공필름인 Sympatex의 경우에는 결로 문제로 인한 착용성이 나쁘며, Nano-web제품의 경우에는 투습성은 좋으나 내수압이 떨어지며, 용제형 코팅제품의 경우에는 견뢰도 저하 및 환경 오염등의 다양한 단점이 속속 도출됨으로써 이에 대한 개선요구가 늘어나고 있는 실정이다.Among these existing products, the PTFE film represented by Gore-tex has a serious problem of curing due to the change in price and aging at a high price. Sympatex, which is a hydrophilic film, is poor in wearability due to condensation, The water permeability is good but the water pressure is low. In the case of the solvent type coating product, various drawbacks such as the lowering of the fastness and the environmental pollution are successively derived, and the demand for the improvement is increasing.
이에 대한민국등록특허제10-0829459호에서는 유기 용제의 사용 없이 다공형 투습방수 원단을 제조하는 방법으로서,(a)원단 준비 공정(b)불소계 발수제를 사용하여 원단을 발수 처리하는 공정(c)열풍으로 열고정하는 공정(d)캘린더링하는 공정(e)상기 캘린더링된 원단의 일면에 나이프 오버 롤 코팅법 또는 플로우팅 나이프 코팅법에 의해 폴리우레탄 코팅 조성물을 코팅하는 공정(f)건조 및 경화하는 공정(g)원단을 50∼80 ℃의 물에 침지하여 수용성 폴리우레탄을 용출시키는 공정 및(h) 원단을 100∼180 ℃에서 건조한 후, 불소계 발수제를 사용하여 발수 가공하여, 미세 다공질 폴리우레탄 막이 형성된 다공형 투습방수 원단을 수득하는 방법을 제시하여 투습성, 방수성, 통기성 등이 우수할 뿐만 아니라 결로(結露) 현상을 방지하여 착용시 쾌적성과 기능성이 탁월한 다공형 투습방수 원단을 제공하고 있다.Thus, Korean Patent No. 10-0829459 discloses a method for producing a porous type breathable and waterproof fabric without using an organic solvent. The method comprises the steps of (a) preparing a fabric, (b) water repellent treatment using a fluorine- (D) a step of calendering (e) a step of coating the polyurethane coating composition on the one side of the calendered fabric by a knife over roll coating method or a floating knife coating method (f) a step of drying and curing (G) a step of dipping the fabric in water at 50 to 80 캜 to elute the water-soluble polyurethane; and (h) the fabric is dried at 100 to 180 캜 and then water-repellent using a fluorinated water- Waterproof, breathable, etc., as well as to prevent condensation (dew condensation) phenomenon, so that the comfort and functionality of the fabric are improved. It provides waterproof breathable multi-layer fabric.

Not only is there difficulty in mixing and working, but also by coating directly on the fabric The thickness of the plated layer was a possibility that an air-permeable and essentially thicker touch to decrease.
따라서 본 발명에서는 상기 선행기술의 문제점을 해결하여 기존의 무공형 기능성 폴리우레탄 필름의 팽윤(swelling)현상을 개선하고, 결로현상이 생기지 않도록 미세 다공성 폴리우레탄 필름 및 수용성 기능성 수지를 이용하여 초박지 직물의 고유 특성인 경량성을 극대화하면서 통기성 및 방풍성, 경량성, 보온성을 동시에 발현하는 미세다공형코팅막을 가지는 초경량 나일론 직물을 제공하는 것을 기술적과제로 한다. Accordingly, the present invention solves the above-mentioned problems of the prior art to improve the swelling phenomenon of the conventional non-porous functional polyurethane film, and to prevent the condensation phenomenon from occurring, the microporous polyurethane film and the water- Lightweight, windproof, lightweight, and warmth at the same time while maximizing light weight It is a technical object to provide an ultralight nylon fabric having a microporous coating film.

이하 본 발명을 보다 상세히 설명하기로 한다. Hereinafter, the present invention will be described in more detail.
본 발명의 미세다공형코팅막을 가지는 초경량 나일론 직물의 제조방법은 초경량 나일론 직물을 제직한 후 그 표면에 폴리우레탄 수지를 주성분으로 하는 미세다공형필름을 코팅함으로써 수용성 폴리우레탄의 미세다공 필름특성과 초경량 나일론직물의 조합에 의한 결로현상방지를 위한 통기형 투습방수 소재를 제조하는 방법이다.The method of producing an ultra lightweight nylon fabric having a microporous coating film of the present invention is characterized in that a microporous film mainly composed of a polyurethane resin is coated on a surface of a lightweight nylon fabric after it is woven, Permeable waterproofing material for preventing condensation due to the combination of nylon fabrics.
본 발명의 초경량 나일론직물은 나일론가연사(SDY 7d/7fila~20d/20fila)로 제직된 직물로서 경사 밀도 313 T/inch, 위사 밀도 276 T/inch, 중량 20.5 g/㎡, 두께 0.04mm, 평직 조직으로 제직된 것을 사용하여 경량화 제품에 적용하고자 한다.The ultra lightweight nylon fabric of the present invention is a woven fabric made of nylon yarn (SDY 7d / 7fila to 20d / 20fila) having an oblique density of 313 T / inch, a weft density of 276 T / inch, a weight of 20.5 g / To be applied to a lightweight product.
상기 초경량 나일론 직물은 코팅작업에 앞서 전발수처리를 하여 발수성을 부여할 수 있는데, 상기 전 발수 처리는 수용성불소계발수제(PG-430, 고형분 30%, 10g/ℓ)를 픽업율 60~70%로 처리한 후 160℃×2분간 처리하게 된다.
The pre-water repellent treatment may be performed by applying a water-soluble fluorinated water repellent (PG-430, solid content 30%, 10 g / l) at a picking rate of 60 to 70% Treated and then treated at 160 ° C for 2 minutes.
이렇게 직물의 전발수처리를 완료한 후 캐스팅한 미세다공형필름을 상기 직물의 표면에 핫멜트 라미네이팅 공정으로 코팅처리을 코팅하게 되는데, 미세다공형필름은 다음과 같은 조성으로 이루어진다. 폴리우레탄수지 65~70중량%, 메틸에틸케톤과 톨루엔의 혼합용제 12~15중량%, 피막방지제 1~5중량%, 가교제 3~5중량%, 소포제 1~3중량%, 안료 5~8중량%, 발수제 1~3중량% 및 실리콘수지 0.5~2중량%로 이루어진 코팅원액 100중량부에 희석용제 30~40중량부를 더 함유한 희석코팅액을 이용하여 나이프오버롤방식으로 이형지에 캐스팅한 미세다공형필름을 준비한다.After completion of the water repellent treatment of the fabric, the microporous film is coated on the surface of the fabric by a hot melt laminating process. The microporous film has the following composition. 1 to 5% by weight of a crosslinking agent, 1 to 3% by weight of a defoaming agent, 5 to 8% by weight of a pigment, 5 to 8% by weight of an antifoaming agent, % Of water-repellent agent, 1 to 3% by weight of water repellent agent and 0.5 to 2% by weight of silicone resin, and a diluting coating solution containing 30 to 40 parts by weight of a diluting solvent is kneaded in a knife- Prepare the film.
상기 폴리우레탄수지는 폴리올(polyol)과 이소시아네이트(isocyanate), 그리고 쇄연장제(chain extender)의 반응을 통하여 분자사슬 내에 우레탄 결합(-NHCOO-)을 가지는 수지로써, 여타 수지들과 비교해 우수한 기계적 물성과 내구성 그리고 동시에 유연성을 가지는 기능성 플라스틱이다. 폴리우레탄 수지가 가지는 유연하고 강인한 특성은 분자 구조상의 유연한 soft-segment와 강직(rigid)한 hard-segment에 의하여 발현되며, 각각의 segment에 어떠한 화학구조의 그리고 어떠한 조성비를 부여하느냐에 따라 폴리우레탄의 중요한 물리적 성질이 결정된다. 일반적으로 soft-segment의 비율이 높으면, 필름의 유연성과 투습도 (친수무공형 투습·방수 필름 경우)등이 증대하나, 탄성계수와 강도와 같은 물리적 특성들이 낮아지며, hard-segment 비율이 높으면 이와 반대의 물성을 보인다. The polyurethane resin is a resin having a urethane bond (-NHCOO-) in a molecular chain through the reaction of a polyol, an isocyanate, and a chain extender, and has excellent mechanical properties Durable and flexible at the same time. The flexible and robust properties of polyurethane resins are manifested by flexible soft-segments and rigid hard segments on the molecular structure. Depending on the chemical structure and composition ratio of each segment, Physical properties are determined. Generally, a high soft-segment ratio increases film flexibility and moisture permeability (for hydrophilic non-permeable moisture-permeable and waterproof films), but decreases physical properties such as elastic modulus and strength.

기존의 직접코팅(direct coating)용 미세다공 수지의 경우에 투습도는 크게 변하지 않았으나, 형성된 필름의 강도가 약하여 쉽게 찢어지며, 피코팅체와의 이형성도 떨어지는 현상을 보였다. 본 발명에서는 투습방수포용 미세다공형 폴리우레탄 수지의 개발 및 코팅층의 물성 향상을 위하여 soft-segment를 이루고 있는 폴리올(polyol), 그리고 hard-segment를 이루는 이소시아네이트(isocyanate)와 쇄연장제(chain extender), 그리고 isocyanate의 변동을 통하여 기계적 물성의 향상을 도모하고 있다In the case of the conventional microporous resin for direct coating, the moisture permeability did not largely change, but the strength of the formed film was so weak that it was easily torn and the releasability with the coating material was also poor. In order to develop a microporous polyurethane resin for a breathable waterproofing fabric and to improve the physical properties of the coating layer, the present invention includes a soft-segmented polyol, a hard-segmented isocyanate and a chain extender, , And the improvement of mechanical properties through the variation of isocyanate
폴리올은 폴리우레탄수지의 화학구조에서 soft-segment부분을 이루며 수지의 탄성과 유연성에 영향을 미치는 분자량 1,000~4,000정도의 저분자 다이올로서 크게 폴리에테르형(PEG, PPG, PTMG)과 폴리에스테르형(PCL), 폴리카보네이트형(poly carbonate type)으로 나눌 수 있으며 본 발명에서는 수지 합성 및 보관 시 안정성의 유지를 위하여, 내한굴곡성 반발탄성 등의 물성이 양호하며 특히 내가수분해성이 polyester polyol과 비교해 우수한 특성을 보이는 폴리에테르형을 선택한다. 그 중에서도 Polytetramethylene glycol(PTMG)은 폴리우레탄수지에 적용시 내마모성, 내가수분해성, 저온 유연성, 내인열성이 우수한 특성을 보일뿐만 아니라 PEG, PPG와 비교해 높은 강도를 나타내어 바람직하다. 특히, 분자량이 1,000~1,200인 것이 기계적 물성과 촉감이 우수하여 바람직하다.Polyol is a low-molecular diol with a molecular weight ranging from 1,000 to 4,000, which forms a soft-segment part in the chemical structure of polyurethane resin and affects the elasticity and flexibility of resin. Polyol (PEG, PPG, PTMG) and polyester PCL) and polycarbonate type. In the present invention, in order to maintain the stability in the synthesis and storage of the resin, it is preferable to use a polyol having good physical properties such as bending strength, rebound resilience and the like, The polyether type is selected. Among them, Polytetramethylene glycol (PTMG) is preferable to polyurethane resin because it exhibits excellent abrasion resistance, hydrolysis resistance, low temperature flexibility and endurance, as well as high strength compared to PEG and PPG. Particularly, a molecular weight of 1,000 to 1,200 is preferable because of excellent mechanical properties and feel.
이소시아네이트(isocyanate)는 크게 방향족(aromatic)계열과, 지방족(aliphatic)계열로 구분할 수 있으며, 방향족(aromatic)계열은 주로 MDI, TDI가 사용되며 지방족(aliphatic)계열은 H12MDI , IPDI 등이 주로 사용된다. 일반적으로 aromatic 계열은 비교적 저가이며, 높은 Tg로 인한 우수한 기계적 물성을 보여 본 발명에 적합하며, 본 발명에서는 비교적 높은 반응성을 가지며, 2개의 -NCO기의 반응성이 같기 때문에 고분자화하기 용이한 4,4-Diphenylmethane diisocyanate (MDI)를 사용한다.Isocyanates can be divided into aromatic and aliphatic series. The aromatic series are mainly MDI and TDI. Aliphatic series are H 12 MDI and IPDI. Is used. In general, the aromatic system is comparatively inexpensive and has excellent mechanical properties due to high Tg, which is suitable for the present invention. In the present invention, since the reactivity is relatively high and the reactivity of two -NCO groups is the same, 4-Diphenylmethane diisocyanate (MDI) is used.
쇄연장제(chain extender)는 이소시아네이트와 반응하여 우레탄기를 형성하면서 사슬과 사슬 사이를 연결시킴으로써 분자량이 큰 폴리우레탄 중합체를 얻는데 이용된다. 폴리우레탄에서 hard-segment를 형성하여 강도, 경도 및 고온물성에 관여 하는 분자량 500 이하의 저분자량체로는 글리콜(glycol)과 디아민(diamine)류로 나눌 수 있는데, 본 발명에서는 경제성과 반응 관리의 향상을 위하여 글리콜(glycol)류의 쇄연장제를 사용한다.
A chain extender is used to obtain a polyurethane polymer having a high molecular weight by linking chains and chains while reacting with isocyanates to form urethane groups. The low molecular weight substance having a molecular weight of 500 or less, which is involved in strength, hardness and high temperature properties by forming a hard segment in polyurethane, can be divided into glycol and diamine. In the present invention, Glycol chain extender is used.
미세다공형 폴리우레탄수지에서 hard-segment의 비율이 증가됨에 따라, 쇄연장제와 디이소시아네이트말단의 반응에 의하여 생성되는 분자 구조적으로 강직성이 큰 -NHCOO-우레탄 결합의 수가 증가되고, 강직성이 높은 hard-segment의 증가에 따라 필름의 강도와 100% modulus가 증대될 수 있으며, 반대로 soft-segment의 증가 시에는 비교적 사슬구조가 유연하고 길이가 긴, 분자량 1,000이상의 -CH2-CH2-CH2-CH2-결합의 반복단위의 수가 증대 되어 필름의 유연성도 동시에 증대되는 것으로 알려지고 있다. 코팅층의 이형성은 hard-segment의 비율이 증대됨에 따라 향상되어 코팅층의 강직성이 증대될수록 피코팅체로부터 쉽게 떨어지는데, 100% modulus가 50 kgf/㎠를 초과할 경우 멤브레인의 강직성이 높아 직물에 적용시 촉감이 딱딱하게 느껴지므로 polyol/isocyanate/chain extender비가 1/2/3일 때 최적의 강도와 이형성 그리고 촉감을 나타낼 수 있다.As the hard-segment ratio increases in the microporous polyurethane resin, the number of -NHCOO-urethane bonds, which are formed by the reaction between the chain extender and the diisocyanate terminal, increases and the rigidity of the molecule increases. -segment, the strength and 100% modulus of the film can be increased. On the contrary, when the soft-segment is increased, a relatively flexible chain structure and a long-chain, -CH 2 -CH 2 -CH 2 - It is known that the number of repeating units of CH 2 - bonds is increased and the flexibility of the film is simultaneously increased. As the hard-segment ratio increases, the releasability of the coating layer increases as the rigidity of the coating layer increases. As a result, the 100% modulus is 50 kgf / cm 2 When the ratio exceeds the above range, the rigidity of the membrane is high, and the feel of the fabric is hard when applied to the fabric. Therefore, when the polyol / isocyanate / chain extender ratio is 1/2/3, it can exhibit optimum strength, releasability and touch.
일반적인 PU수지의 중합 시에는 DMF, Toluene, MEK, NMP, EA등의 용제를 주로 사용하여 합성을 실시하며, 때로는 이들을 공용매를 이용하여 상용성(compatibility)을 증가시키는데, 본 발명에서는 Methyl ethyl ketone(MEK)를 사용한다. 그외에 폴리우레탄 결합의 반응성의 향상을 위하여 dibutyl tin catalyst와 bismuth catalyst를 촉매로 사용하였으며, 촉감 개질 및 이형성의 향상을 위하여 실리콘오일을 실험에 사용하였다. 또한 aromatic diisocyanate의 quinonoide화에 의하여 발생하는 수지의 황변 현상, 그리고 isocyanate와 수분과의 반응으로 인하여 발생하는 diamine화 현상과 같은 제품의 색상의 변화 및 원치 않는 물성의 저하를 막기 위하여 광안정제와 UV방지제를 혼합하여 사용하며, 산화방지제와 열안정제를 수지의 안정성을 위하여 사용한다. In general, PU resin is synthesized by using a solvent such as DMF, Toluene, MEK, NMP and EA. Sometimes, compatibility thereof is increased by using a co-solvent. In the present invention, Methyl ethyl ketone (MEK) is used. In addition, dibutyl tin catalyst and bismuth catalyst were used as catalysts for improving the reactivity of polyurethane bond, and silicone oil was used for the experiment to improve the tactile modification and releasing property. Also, in order to prevent changes in the color of the product and deterioration of the unwanted physical properties such as diaminization caused by the reaction of isocyanate with water, yellowing of resin caused by quinonoide of aromatic diisocyanate, And antioxidants and heat stabilizers are used for the stability of the resin.
본 발명에서는 상기 합성된 폴리우레탄수지 65~70중량%, 메틸에틸케톤과 톨루엔의 혼합용제 12~15중량%, 피막방지제 1~5중량%, 가교제 3~5중량%, 소포제 1~3중량%, 안료 5~8중량%, 발수제 1~3중량% 및 실리콘수지 0.5~2중량%로 이루어진 코팅원액을 준비한다. 기존 다이렉트 코팅용 미세다공형 폴리우레탄 수지의 문제점인 작업중 표면에 스키닝(skinning)이 발생하는 현상은 코팅시 멤브레인 형성을 방해하며, 멤브레인 형성시 강도 저하를 유발하게 되는데, 본 발명에서는 피막방지제를 첨가하여 스키닝(skinning) 발생을 방지할 수 있다. 또한, 코팅 멤브레인의 강도를 증가시키기 위해서 가교제를 상기와 같이 첨가하였으며, 상기 가교제의 함량은 내수압 및 투습도에는 영향을 주지 않았다.In the present invention, the polyurethane resin is used in an amount of 65 to 70% by weight, 12 to 15% by weight of a mixed solvent of methyl ethyl ketone and toluene, 1 to 5% by weight of an anti-filming agent, 3 to 5% by weight of a crosslinking agent, 5 to 8% by weight of a pigment, 1 to 3% by weight of a water repellent agent and 0.5 to 2% by weight of a silicone resin. In the present invention, skinning occurs on the surface of the microporous polyurethane resin, which is a problem of the existing direct coating microporous polyurethane resin, which hinders formation of the membrane during coating and causes a decrease in strength when the membrane is formed. Thereby preventing occurrence of skinning. Also, in order to increase the strength of the coating membrane, a crosslinking agent was added as described above, and the content of the crosslinking agent did not affect water pressure and moisture permeability.
일반적으로 수지 배합시 기포가 발생하며, 이러한 기포를 제거하기 위해서 탈포공정을 거치지만, 기포가 완전히 제거되지는 못한다. 잔존하는 기포가 피막 형성시 핀홀(pin hole)을 발생시키며 이에 따른 내수압 및 인장강도 저하를 유발하는데, 본 발명에서는 상기 비율의 소포제(실리콘계 계면활성제)를 투입하여 잔존하는 기포를 완전히 제거하였으며, 코팅막의 내수압 및 인장강도를 증가시킬 수 있다.Generally, bubbles are generated when the resin is blended, and in order to remove such bubbles, a defoaming process is performed, but the bubbles are not completely removed. Residual bubbles generate pinholes at the time of film formation and cause a decrease in water pressure and tensile strength. In the present invention, the bubbles remaining in the coating film are completely removed by injecting the defoaming agent (silicone surfactant) It is possible to increase the water pressure and the tensile strength.
한편, 기본적으로 수지 배합시 발수제를 첨가하지 않으면, 수압이 가해질 때 셀(cell) 내부로 물이 침투하게 되어 셀이 파괴됨으로써 내수압 크게 저하된다. 이러한 문제를 해결하기 위해서 발수제를 첨가한다. 본 발명에서는 멤브레인의 내마모성을 증가시키기 위해서 발수제를 첨가하였다.
On the other hand, if a water repellent agent is not added during the resin blending, water will penetrate into the cell when the water pressure is applied, and the cell will be destroyed, resulting in a drastic decrease in water pressure. To solve this problem, a water repellent agent is added. In the present invention, a water repellent agent is added to increase the abrasion resistance of the membrane.
상기 코팅원액을 준비한 후 본 발명에서는 상기 코팅원액 100중량부에 희석용제(물과 MEK의 혼합물) 30~40중량부를 더 함유한 희석코팅액을 만들어 나이프오버롤방식으로 이형지에 캐스팅한 미세다공형필름을 준비하게 된다. 본 발명에서 미세다공형코팅막을 이형지표면에 형성하기 위해서는 혼합용제가 먼저 증발을 하면서 피막을 형성하고, 그 다음 물이 증발하면서 그 자리에 기공이 발생하게 된다. 상기 희석용제의 물의 함량에 따라서 기공의 형상이 좌우되는데, 기공이 많이 생성되면, 내수압 및 인장강도가 저하되고, 상대적으로 투습도가 증가하게 되는 특성을 가지며, 기공이 적게 생성되면, 반대의 특성을 보인다. 따라서 본 발명에서는 물과 MEK의 중량비를 40:5 ~ 50:5로 조절하는 것이 바람직하다. 물의 함량이 많아질수록 내수압 및 인장강도가 저하되고, 투습도가 증가하는 결과를 보였으며, 중량비가 50이상인 때는 점도가 높아서 코팅하기에 적합하지 않았다.After preparing the coating stock solution, a dilute coating liquid containing 30 to 40 parts by weight of a diluting solvent (a mixture of water and MEK) is prepared in 100 parts by weight of the coating stock solution, and a microporous film is cast on a release paper by knife- I am ready. In the present invention, in order to form a microporous coating film on a release surface, a mixed solvent is first evaporated to form a coating film, and then water is evaporated to generate pores in situ. The shape of the pores depends on the content of water in the diluting solvent. When a large amount of pores are generated, the water pressure and the tensile strength are lowered and the moisture permeability is increased. see. Therefore, in the present invention, it is preferable to control the weight ratio of water to MEK to 40: 5 to 50: 5. As the content of water increased, the water pressure and tensile strength decreased and the moisture permeability increased. When the weight ratio was more than 50, the viscosity was too high to be suitable for coating.
