본 발명은 아라미드섬유를 함유하는 실로 제직된 직물을 실리콘계코팅액으로 코팅하여 난연성 및 내열성을 저하시키지 않으면서도 필링성이 우수한 산업안전작업복용 직물을 제공하는 것이다.The present invention provides a fabric for industrial safety work wear which is coated with a silicone-based coating liquid containing a aramid fiber-containing yarn, and has excellent peeling properties without deteriorating flame retardancy and heat resistance.
Description
본 발명은 산업안전작업복에 적용할 수 있는 직물에 내열성의 저하가 없으면서 필링방지에 의한 내구성 향상을 위한 실리콘코팅방법에 관한 것이다. The present invention relates to a silicone coating method for improving durability by preventing peeling while not deteriorating the heat resistance of a fabric applicable to industrial safety workwear.
산업현장에서 작업자가 착용하는 안전작업복은 고강도, 내열성 및 내화학성을 필요로 한다. 예를 들면 위험한 용도에 사용되는 방탄복, 공업용 작업복, 소방복 및 군인의 보호복은 면이나 모와 같은 비합성 섬유로 된 실로 짠 직물로 만든 후 이들 직물을 통상적인 할로겐과 인 또는 이들 중 하나에 기초한 내화제로 처리하여 사용하였는데, 이러한 작업복은 활동에 제한을 받고 일반적인 비내열성 직물보다 더 무거운 문제가 있었다. Safety work clothes worn by workers at industrial sites require high strength, heat resistance and chemical resistance. For example, protective garments used in dangerous applications, industrial garments, fire extinguishers and military garments may be made of yarn woven of non-synthetic fibers, such as cotton or wool, and then those fabrics may be treated with conventional halogen and phosphorus, The work clothes were limited in activity and were heavier than normal non-heat resistant fabrics.
상기 산업안전작업복 중에서도 특히 용접 작업시 착용하는 용접복은 내열성 및 난연성이 더욱 필요로 하는 작업복에 속한다. 특히 아크 용접 작업시에는 용접작업 과정에서 많은 불꽃이 튀며, 전기에 의한 감전, 용접시 발생되는 고온의 열기 및 작업장에서 예상치 못한 외부 충격 등의 위험요소가 상존하고 있다.Among the above-mentioned industrial safety work clothes, a welded garment to be worn during the welding work belongs to a work garment which requires more heat resistance and flame retardancy. Especially, in arc welding work, many sparks are splashed during the welding work, and there are risks such as electric shock, high temperature heat generated in welding, and unexpected external impact in the workplace.
이러한 위험요소로부터 작업자를 보호하기 위해 용접복, 용접 마스크 및 용접 장갑 등의 용접용 보호장구(Welding Gear)를 착용하게 되며, 이 중 용접복은 특히 자신의 신체의 대부분을 보호하기 때문에 다른 보호장구에 비해 더 중요하다. 종래의 용접복은 동물의 가죽으로 제작되었는데, 이와 같이 가죽으로 제작된 용접복은 용접 작업시 불꽃이 튀어 닿게 되면 고온의 열에 의해 쉽게 오그라들거나 소실되며, 무겁고 불편할 뿐 아니라 통풍이 되지 않는 문제점이 있었다.In order to protect workers from these hazards, Welding Gears such as welding belts, welding masks and welding gloves are worn. Among them, welding belts protect most of their bodies, . Conventional welding belts are made of animal leather. Such welding belts made of leather are easily shrunken or lost due to high-temperature heat when the spark plug is touched during the welding work, and are not only heavy and inconvenient but also do not ventilate .
이에 다양한 섬유로 만든 직물에 난연제처리를 하는 경우가 많았는데, 난연제는 유기계(인계, 질소계, 할로겐계) 및 무기계(금속수산화물, 안티몬계)로 구별된다. 유기계 난연제 중 대표적인 할로겐계 난연제는 연소의 추진역할을 하는 활성라디칼(OH·, H·)을 할로겐 화합물인 HX가 연소과정에서 포착함으로서 그 난연효과를 발휘한다. 또한 HX는 불연성가스를 발생시킴으로써 가연성가스를 희석시키고 산소도 차단하는 효과를 가진다. 그러나 이때 발생하는 할로겐가스는 금형 및 전선 등의 금속을 부식시켜 베이스폴리머나 장비에 치명적인 영향을 줄 수 있을 뿐만 아니라 인체에도 유해한 문제점을 가진다. Therefore, flame retardants are often applied to fabrics made from various fibers. Flame retardants are classified into organic (phosphorous, nitrogen, halogen) and inorganic (metal hydroxide, antimony). Representative halogen-based flame retardants among organic flame retardants exhibit their flame-retarding effect by capturing the active radicals (OH., H.) Which act as a propellant of combustion in the combustion process of HX, which is a halogen compound. In addition, HX has the effect of diluting combustible gas and blocking oxygen by generating incombustible gas. However, the halogen gas generated at this time has a detrimental effect on the human body as well as a fatal effect on the base polymer or equipment by corroding metals such as molds and electric wires.
한편, 무기계 난연제는 난연제 중에서 사용량이 가장 많은 수산화알루미늄Al(OH)3는 470cal/g의 흡열량에 의해 난연효과를 크게 나타내고 있는데, 이러한 수산화금속화합물의 난연효과는 입자 크기나 입도 분포, 불순물, Na2O의 감량 등이 있으며 Al(OH)3의 난연효과를 높이기 위한 또 다른 방법으로는 충진량을 높이는 방법이 있고, 기계적 성질을 향상시키기 위해 표면처리기술이 연구되고 있는데, 충분한 난연성 및 내열성을 확보하기 위해서는 충진량을 높이거나 입자크기를 작게 해야 하지만, 이 경우 코팅 분산성 문제를 초래하므로 적정 함량을 사용하는 것이 관건이다.On the other hand, in the inorganic flame retardant, aluminum hydroxide (Al) (OH) 3, which has the largest amount of flame retardant, exhibits a large flame retarding effect due to the heat absorption amount of 470 cal / g. The flame retarding effect of the metal hydroxide compound depends on the particle size, And the reduction of Na 2 O. Another method to increase the flame retarding effect of Al (OH) 3 is to increase the filling amount. To improve the mechanical properties, surface treatment technology is being studied. It has sufficient flame retardancy and heat resistance However, in order to achieve the coating dispersion problem, it is important to use an appropriate amount.
또한, 안티몬계 난연제는 주로 할로겐계 난연제와 병용하여 사용하거나 할로겐을 포함하고 있는 PVC, CPE와 같은 수지에 사용됨으로써 큰 난연효과의 상승작용을 얻을 수 있어 많이 사용되어져 왔으나 안티몬계 난연제는 가격이 불안정하고 연소시 유독가스를 배출하는 문제점을 가지고 있다. Antimony based flame retardants have been widely used because they are used in combination with halogen-based flame retardants or halogen-containing resins such as PVC and CPE to obtain a synergistic effect of a large flame retardant effect. However, antimony- And there is a problem that toxic gas is emitted when it is burned.
이러한 이유로 최근에는 비연소성 및 내열성이 우수한 파라-아라미드, 메타-아라미드, 탄화섬유, PBO, 방염성 레이온등의 고강도ㆍ고내열성 섬유를 이용한 용접복을 개발하기에 이르렀으나 이러한 직물은 우수한 열적안정성은 보였지만 단섬유 형태여서 방적사로 제조하여 사용하는 경우가 많았으며, 이러한 고강도ㆍ고내열성 섬유의 방적사의 경우에 필링성이 좋지 못한 문제점을 가지고 있었으며, 이러한 필링성을 개선하기 위해서는 수지가공을 하여야 하였으나 내열성이 저하되는 문제점을 가지고 있었다.For this reason, in recent years, the development of welded fabrics using high-strength and high-temperature-resistant fibers such as para-aramid, meta-aramid, carbon fiber, PBO, and flame retardant rayon excellent in non-combustibility and heat resistance has been developed. In case of spun yarn of high strength and high heat resistance fiber, the filing property was not good. In order to improve the peeling property, it was necessary to process resin, but heat resistance And had a problem of deteriorating.
그러므로 본 발명은 상기 종래기술의 문제점을 해결하여 인체에 무해하면서도 친환경적일뿐만 아니라 난연성 및 내열성을 저하시키지 않으면서도 필링성이 개선된 산업안전작업복용 직물의 고내열성 실리콘코팅방법을 제공하는 것을 기술적과제로 한다.
SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a highly heat-resistant silicone coating method for fabrics for occupational safety work which is harmless to the human body and is environmentally friendly as well as improving peelability without deteriorating flame retardancy and heat resistance. .
따라서, 본 발명에 의하면 고강도ㆍ고내열성 실로 제직된 직물을 하기 화학식 1 기재의 실리콘폴리머 85~95중량% 및 하기 화학식 2의 구조를 갖는 가교제 5~15중량%로 이루어진 실리콘계코팅액으로 코팅하는 것을 특징으로 하는 산업안전작업복용 직물의 고내열성 실리콘코팅방법이 제공된다.Therefore, according to the present invention, the fabric woven with a high strength and high heat resistance yarn is coated with a silicon-based coating solution composed of 85 to 95% by weight of a silicone polymer represented by the following
[화학식 1][Chemical Formula 1]

And R < 2 > is H, m = 650 to 800.
[화학식 2](2)
[상기 R3는 H 또는 CH3이고, o = 40~70 임.]
[Wherein R 3 is H or CH 3 and o = 40 to 70.]
이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명은 고강도ㆍ고내열성 실로 제직된 직물을 실리콘계코팅액으로 코팅하여 우수한 난연성 및 내열성을 가지면서도 필링성이 우수한 산업안전작업복용 직물을 제공하는 것이다.
The present invention provides a fabric for industrial safety workwear having excellent flame retardancy and heat resistance and excellent peelability by coating a fabric woven with a high strength and high heat resistance yarn with a silicone coating liquid.
본 발명에서는 고강도ㆍ고내열성 실로 제직된 직물을 하기 화학식 1 기재의 실리콘폴리머 85~95중량% 및 하기 화학식 2의 구조를 갖는 가교제 5~15중량%로 이루어진 실리콘계코팅액으로 코팅한다.In the present invention, the fabric woven with a high strength and high heat resistance yarn is coated with a silicone-based coating solution composed of 85 to 95% by weight of a silicone polymer represented by the following formula (1) and 5 to 15% by weight of a crosslinking agent having a structure represented by the following formula (2).
[화학식 1][Chemical Formula 1]
[상기 R1은 H 또는 CH3이며,[Wherein R 1 is H or CH 3,
상기 R2는 H, m = 650~800 임.]
And R < 2 > is H, m = 650 to 800.
[화학식 2](2)
[상기 R3는 H 또는 CH3이고, o = 40~70 임.]
[Wherein R 3 is H or CH 3 and o = 40 to 70.]
상기 실리콘계 코팅액의 주성분인 화학식 1 기재의 실리콘폴리머는 규소(Si)와 산소(O)의 전기음성도 차이가 커 에너지적으로 매우 안정되어 열과 산화에 강하며 고온에서 사용되는 경우 안정적인 폴리머이다. 또한, 분자 구조상 실록산(Si-O-Si)에 기인하는 무기적 특성 때문에 내열성, 화학적 안정성, 전기절연성, 내마모성이 우수하다. 특히 상기 화학식 1기재의 실리콘폴리머는 일반 실리콘폴리머에 비하여 이중결합을 가지고 있기 때문에 가교제와 반응하여 네트워크 구조를 형성할 수 있어 고분자 피막형태로 직물표면에 균일하게 도포되어 고내열성의 저하방지에 바람직하다. The silicon polymer of formula (1), which is a main component of the silicon-based coating solution, is a stable polymer when it is used at high temperatures because it has strong energy and is resistant to heat and oxidation because of the difference in electronegativity between silicon (Si) and oxygen (O). In addition, it is excellent in heat resistance, chemical stability, electrical insulation and abrasion resistance because of the inorganic property due to siloxane (Si-O-Si) on the molecular structure. In particular, since the silicone polymer of Formula 1 has a double bond as compared with a general silicone polymer, it can form a network structure by reacting with a crosslinking agent, and is uniformly applied to the surface of a fabric in the form of a polymer film to prevent deterioration of high heat resistance .
일반적으로 주성분인 실리콘계 코팅액에 내열성을 상승시키기 위해서는 난연제를 사용하는데, 이러한 난연제는 폴리머의 연소과정 중 가열ㆍ분해ㆍ발열 등의 특정한 연소단계를 방해함으로써 연소를 억제하거나 완화시켜 난연효과를 나타낸다. Generally, a flame retardant is used to increase the heat resistance of the silicone coating liquid, which is the main component. Such a flame retardant inhibits or softens combustion by preventing specific combustion stages such as heating, decomposition, and heat generation during the combustion process of the polymer.
그러나 본 발명에서는 상기 난연제를 함유하지 않는 실리콘계 코팅액을 제공함으로써 환경문제나 독성문제가 없는 고내열성을 발현하는 코팅방법을 제공하는 것이다. However, the present invention provides a silicone-based coating solution containing no flame retardant to provide a coating method exhibiting high heat resistance without environmental problems or toxicity problems.
특히, 난연제를 사용하는 경우에는 난연제가 입자 형태로 코팅제와 함께 직물표면에 분포하게 되어 균일한 코팅처리가 되지 못하고, 이로 인해 필링성 문제가 해결되지 않는데 반해, 본 발명에 의해 코팅된 직물은 직물 표면에 코팅제가 균일하게 존재하도록 하여 직물의 필링성 문제를 해결하는 것이다.In particular, in the case of using a flame retardant agent, the flame retardant agent is dispersed on the surface of the fabric together with the coating agent in the form of particles, so that the uniformity of the coating treatment can not be obtained and thus the problem of peeling can not be solved. And the coating agent is uniformly present on the surface, thereby solving the problem of peeling of the fabric.
기존의 고강도ㆍ고내열성 실을 사용한 직물과 같이 직물 표면에 필링이 발생하게 되면 마찰 강도가 감소하고, 피부에 자극적이며 외관상 좋지 않다. 이러한 문제점을 해결하기 위하여 본 발명에서는 고강도ㆍ고내열성 실을 사용한 직물을 실리콘계 코팅제로 표면을 피복하였다. 고강도ㆍ고내열성 실은 주로 방적사로서 필라멘트사에 비하여 표면에 단섬유가 많이 분포하기 때문에 외부 힘에 의해 섬유끼리 서로 엉키는 현상이 발생하기 쉽다. 이러한 필링을 방지하기 위하여 직물 표면에 코팅층을 형성하여 표면에 위치한 섬유를 고정시켜 엉킴 현상을 감소시킬 수 있으며, 코팅 층이 외부로부터 섬유를 보호할 수 있어 필링 현상을 감소시킬 수 있는 것이다. When peeling occurs on the surface of a fabric as in the case of a fabric using a conventional high-strength and high-heat-resistant yarn, the friction strength is reduced, the skin is irritating, and the appearance is not good. In order to solve such a problem, in the present invention, a fabric using a high-strength and high-temperature-resistant yarn is coated with a silicone-based coating agent. The high strength and high heat resistance yarn are mainly spun yarn, because the short fibers are distributed on the surface much more than the filament yarn, so that the fibers tend to tangle with each other due to the external force. In order to prevent such peeling, a coating layer may be formed on the surface of the fabric to fix the fibers located on the surface to reduce entanglement, and the coating layer can protect the fibers from the outside, thereby reducing the peeling phenomenon.
본 발명의 실리콘계코팅액은 화학식 1 기재의 실리콘폴리머 85~95중량% 및 가교제 5~15중량%로 이루어지는데, 가교제는 화학식 1 기재의 실리콘폴리머와 가교를 이룰수 있도록 하는 것으로서 하기 화학식 2의 구조를 갖고 백금촉매를 미량함유하는 것으로서 pH : 7.0±0.5, 비중 : 0.996±0.001, 점도 : 1,000cP 미만, 분자량 : 3,000~5,000인 것이 실리콘계 코팅제를 완전 경화시키는데 특히 바람직하다.
The silicone-based coating liquid of the present invention comprises 85 to 95% by weight of the silicone polymer of Formula 1 and 5 to 15% by weight of a crosslinking agent. The crosslinking agent is capable of crosslinking with the silicone polymer of Formula 1, Containing a trace amount of a platinum catalyst and having a pH of 7.0 ± 0.5, a specific gravity of 0.996 ± 0.001, a viscosity of less than 1,000 cP and a molecular weight of 3,000 to 5,000 is particularly preferable for completely curing a silicone coating agent.
[화학식 2](2)
[상기 R3는 H 또는 CH3이고, o = 40~70 임.]
[Wherein R 3 is H or CH 3 and o = 40 to 70.]
상기 실리콘폴리머는 비중 0.97~1.07, 점도 9,000~10,000cP, 분자량 50,000~70,000 및 평균분자량 55,000~65,000인 것이 필름 형성능에 바람직하다. 본 발명의 상기 화학식 1의 실리콘폴리머는 말단에 이중결합을 포함하고 있기 때문에 코팅제의 주구조가 되는 선(linear)상 폴리머가 가교제와 반응하여 블록코폴리머(block-copolymer)를 형성하여 네트워크 구조를 형성할 수 있다. 선상의 폴리머 구조는 열이나 힘에 의해 결합이 쉽게 끊어지기 쉬우나, 상기 블록코폴리머는 네트워크 구조를 형성해 거대고분자로 변화해 구조적으로 안정되어 필름형성능을 향상시키게 된다.
The silicone polymer preferably has a specific gravity of 0.97 to 1.07, a viscosity of 9,000 to 10,000 cP, a molecular weight of 50,000 to 70,000, and an average molecular weight of 55,000 to 65,000. Since the silicone polymer of Formula 1 of the present invention has a double bond at the terminal, the linear polymer as a main structure of the coating agent reacts with the crosslinking agent to form a block copolymer, . The linear polymer structure tends to be easily broken due to heat or force, but the block copolymer forms a network structure and changes to a macromolecular structure to be structurally stable, thereby improving the film forming ability.
본 발명에서 상기 고강도ㆍ고내열성 실은 파라-아라미드, 메타-아라미드, 탄화섬유, PBO, 방염성레이온 중 어느 하나이상을 함유한 고강도ㆍ고내열성 실이 바람직하다. 특히 그 혼합형태는 안전작업복의 용도별로 혼합방적사, 복합가연사, 에어텍스쳐사 및 합연사 중 어느 하나인 것을 사용할 수 있다.In the present invention, the high-strength and high-temperature-resistant yarn is preferably a high-strength, high-heat-resistant yarn containing at least one of para-aramid, meta-aramid, carbon fiber, PBO and flame retardant rayon. In particular, the blended yarn may be any one of mixed yarns, mixed yarn yarns, air texture yarns, and sliver yarns for each use of the safety workwear.
본 발명에서 직물을 코팅하기 위한 방법으로는 디핑법, 롤러코팅, 나이프코팅 등의 여러 가지 방법을 사용할 수 있겠으나, 직물의 태와 항필링성을 위해 나이프코팅방법을 사용하는 것이 바람직하다. 나이프코팅 후 170~180oC로 코팅액을 경화시켜 산업안전작업복용 직물을 제공하게 된다.In the present invention, various methods such as dipping method, roller coating, and knife coating can be used as a method for coating the fabric, but it is preferable to use a knife coating method for the woven and knitted. After knife coating, the coating solution is cured at 170 to 180 ° C to provide industrial safety workwear fabrics.
따라서 본 발명의 고내열성 실리콘코팅방법에 의하면 인체에 무해하면서도 친환경적일뿐만 아니라 난연성 및 내열성을 저하시키지 않으면서도 필링성이 우수한 산업안전작업복용 직물을 제공할 수 있다.
Therefore, according to the high heat-resistant silicone coating method of the present invention, it is possible to provide a fabric for industrial safety work, which is harmless to the human body and is not only environmentally friendly but also excellent in peelability without deteriorating flame retardancy and heat resistance.
