Abstract
Description
본 발명은 친환경적인 수용성우레아 PUD (polyurea dispersion) 수지와, 항균 및 악취제거와 휘발성유기물 제거 및 중금속 흡착과, 원적외선 방사 또는 청결 유지를 위해 제오라이트(Zeolite)분말을 포함하는 장갑 코팅용 조성물과, 조성물로 코팅된 수용성우레아코팅 장갑 및 그 제조방법에 관한 것이다. The present invention provides an environmentally friendly water-soluble urea PUD (polyurea dispersion) resin, antibacterial and odor removal, volatile organic matter removal, heavy metal adsorption, and far-infrared radiation or a composition for coating gloves comprising a zeolite powder for maintaining cleanliness, and a composition It relates to a water-soluble urea-coated glove and a method for manufacturing the same.
일반적으로 산업현장에서 근무하는 작업자는 손을 보호하거나 작업물의 오염을 방지하기 위하여 장갑을 착용하게 되는데, 이러한 장갑은 그 목적에 따라 면이나 나일론 등의 다양한 종류의 섬유를 사용하여 제조된다. 그러나, 이와 같이 섬유를 단순 직조하여 제조된 장갑은 미끄러운 물건의 취급에는 용이하지 못한 단점을 가지고 있다.In general, workers working at industrial sites wear gloves to protect their hands or prevent contamination of their work, and these gloves are manufactured using various types of fibers such as cotton or nylon depending on the purpose. However, the gloves manufactured by simply weaving fibers as described above have a disadvantage in that it is not easy to handle slippery objects.
이러한 문제점을 해소하기 위하여 도 1에 도시된 바와 같이, 장갑을 고무액을 포함하는 코팅액에 일정 시간 동안 함침 시킨 후 꺼내어 건조함으로써 장갑의 표면에 고무 코팅층을 형성시켜 사용하는 개선책이 제시되었다. 그러나, 종래 장갑의 표면에 코팅층을 형성하기 위하여 사용되는 우레탄이나 PVC수지 코팅액은 내구성이 떨어지는 단점을 가지고 있다.In order to solve this problem, as shown in FIG. 1 , an improvement method of using the glove by forming a rubber coating layer on the surface of the glove by immersing the glove in a coating solution containing a rubber solution for a certain time and then taking it out and drying it was suggested. However, the conventional urethane or PVC resin coating solution used to form a coating layer on the surface of the glove has a disadvantage of poor durability.
최근에는 내구성을 강화하기 위해 코팅액의 주재로 NBR수지를 사용하는 기술이나 우레탄수지를 사용하는 기술이 제안되었다. 보다 구체적으로는 NBR수지또는 우레탄수지를 주재로 하는 코팅액에 장갑의 내피를 침적시킨 다음 건조하여 코팅장갑을 제조하는 것으로서, 이와 같이 NBR수지나 우레탄수지를 주재로 하는 코팅액을 사용하는 경우 내구성이 증진될 뿐만 아니라 사용분야가 다양해지는 이점이 있다. 그러나, 상기와 같이 단순한 침적방법에 의해 장갑을 제조하는 경우 수지 코팅액이 장갑의 내부 깊숙이 침투하여 경화됨에 따라 착용감이 떨어져 착용자가 불편함을 느낄 뿐만 아니라 작업과정에서 손에서 발생하는 땀이 장갑에 흡수되지 못하여 불쾌하고 악취가 발생하는 단점이 있는 바, 당 업계에서는 기존 보호용 PU, PUD 또는 NBR 코팅 장갑의 내구성을 유지 및 개선 시키면서 흡수하지 못한 땀에 의한 악취제거, 피부에 민감한 작업자의 보호, 음이온 방출로 인한 건강증진 효과를 나타내는 기능성 장갑의 개발 필요성이 대두 되고 있었다.Recently, in order to strengthen the durability, a technique using NBR resin or a technique using urethane resin as the main material of the coating solution has been proposed. More specifically, coating gloves are manufactured by immersing the inner skin of gloves in a coating solution mainly made of NBR resin or urethane resin, and then drying. Not only that, but there is an advantage that the field of use is diversified. However, when the glove is manufactured by the simple immersion method as described above, the resin coating solution penetrates deep inside the glove and hardens, so the wearer feels uncomfortable and the sweat generated from the hand is absorbed into the glove. In the industry, it maintains and improves the durability of existing protective PU, PUD or NBR-coated gloves, while removing odors from sweat that cannot be absorbed, protecting workers with sensitive skin, and releasing negative ions. Therefore, the need for the development of functional gloves showing health-promoting effects was emerging.

한편, 본 발명의 강화재로 사용되는 제오라이트(Zeolite)는 SiO2가 주성분인 약알칼리성의 암석분말인 장석류 광물의 일종으로서, 나노 크기의 세공(細孔)이 무수히 존재하며, 그 세공속에는 보통 물분자들이 가득 채워져 있고 일정한 열이 가해지면 내포된 물분자가 증발하여 수증기를 발산한다. 이러한 사실에 기인하여 끓는(zeo)돌(lite)이라고 명명되기도 한다.On the other hand, zeolite used as a reinforcing material of the present invention is a kind of feldspar mineral, which is a weakly alkaline rock powder containing SiO 2 as a main component, and has a myriad of nano-sized pores. When they are filled and constant heat is applied, the contained water molecules evaporate and emit water vapor. Due to this fact, it is also called boiling (zeo) stone (lite).

본 발명에서는 이와 같은 제오라이트(Zeolite)을 특성을 장갑에 접목하여, 기본적인 장갑의 기능 이외에 착용자의 손에서 발생하는 땀에의한 냄새탈취 및 항균효과를 향상시킬 수 있다.In the present invention, such properties of zeolite are grafted to gloves, so that, in addition to the basic functions of gloves, odor deodorization and antibacterial effects caused by sweat generated from the wearer's hands can be improved.
본 발명의 조성물에 첨가되는 제오라이트(Zeolite)는 분말 또는 겔상의 분말을 이용할 수 있으며, 실험결과 제오라이트(Zeolite)분말의 중량 8%이하인 경우 악취제거, 항균, 휘발성 유기물 제거, 중금속 흡착, 원적외선 방사 등의 효과가 떨어지는 것이 확인되었으며, 더욱이 코팅용 조성물이 장갑과의 결합을 방해하여 코팅율이 떨어지거나 질감이 나빠지는 문제점이 있었다. Zeolite added to the composition of the present invention may be powder or gel powder, and as a result of the experiment, if the weight of Zeolite powder is 8% or less, odor removal, antibacterial, volatile organic matter removal, heavy metal adsorption, far-infrared radiation, etc. It was confirmed that the effect of the coating was lowered, and moreover, there was a problem in that the coating composition interfered with the bonding with the glove, so that the coating rate decreased or the texture deteriorated.
본 발명의 일 실시예로, 주재로서 수용성 우레아 PUD(Urea Polyurethane Dispersion) 또는 NBR(Nitrile Butadiene Rubber) 중 어느 하나로 이루어진 합성수지는 35∼45 중량%; 보조재로서 소포제, 정포제, 증점제, 가교제, 가교조제 및 분산제를 포함하여 이루어진 첨가제는 20∼25 중량%; 강화재로서 제오라이트(Zeolite)는 고형화된 분말 또는 겔상의 분말로 구성되는 8∼35 중량% 으로 구성되는 될 수 있다. 또한, 본 발명의 다른 실시예로, 주재:보조재:강화재의 중량비는 40∼55 : 25∼40: 5∼25 로 구성될 수도 있다. In one embodiment of the present invention, the synthetic resin made of any one of water-soluble urea PUD (Urea Polyurethane Dispersion) or NBR (Nitrile Butadiene Rubber) as a main material is 35-45 wt%; An additive comprising an antifoaming agent, a foaming agent, a thickener, a crosslinking agent, a crosslinking aid and a dispersing agent as an auxiliary material is 20 to 25% by weight; Zeolite as a reinforcing material may be composed of 8 to 35% by weight of solidified powder or gel-like powder. In addition, in another embodiment of the present invention, the weight ratio of the main material: the auxiliary material: the reinforcing material may be 40 to 55: 25 to 40: 5 to 25.
본 발명의 가장 바람직한 실시예로서, 중량비를 기준으로 수용성 우레아 PUD(Urea Polyurethane Dispersion) 주재:보조재:강화재의 중량비율은 40:35:25 이다. As a most preferred embodiment of the present invention, based on the weight ratio, the weight ratio of water-soluble urea PUD (Urea Polyurethane Dispersion) main material: auxiliary material: reinforcing material is 40:35:25.
따라서, 본 발명은 상기 수용성 우레아 PUD(Urea Polyurethane Dispersion) 또는 NBR(Nitrile Butadiene Rubber)의 적용에 의해, 종래 유성 폴리우레탄(PU; PolyUrethan)을 사용하는 코팅장갑의 문제점인 유해성 디메틸포름아미드(DMF)를 완전히 제거하면서, 제오라이트(Zeolite)를 부가하여 일반코팅장갑에 비해서 내절창성 및 내열성은 보다 우수하고, 인장 강도 및 내 마모도는 동등 이상의 개선된 코팅장갑을 구현할 수 있게 된다. Therefore, the present invention is a problem of coating gloves using conventional oil-based polyurethane (PU; PolyUrethan) by application of the water-soluble urea PUD (Urea Polyurethane Dispersion) or NBR (Nitrile Butadiene Rubber), harmful dimethylformamide (DMF) While completely removing the zeolite, it is possible to implement improved coating gloves with better cut resistance and heat resistance, tensile strength and wear resistance equivalent to or higher than that of general coated gloves by adding zeolite.
이와 같은 본 발명의 코팅장갑의 제조방법은 도 3에 도시된 바와 같이, 장갑 코팅용 조성물 준비단계(S10); 표면 코팅단계(S20); 장갑표면에 코팅된 조성물의 응고 및 경화단계(S30); 코팅장갑의 세척 및 건조단계(S40)을 거쳐 제조된다. As shown in FIG. 3, the method for manufacturing the coated glove of the present invention as described above includes a glove coating composition preparation step (S10); surface coating step (S20); Coagulation and curing of the composition coated on the surface of the glove (S30); It is manufactured through the washing and drying step (S40) of the coated gloves.
첫번째, 장갑 코팅용 조성물의 준비단계(S10)는 전술한 바와 같이, 코팅장갑에 사용되는 조성물인 수용성 우레아 PUD(Urea Polyurethane Dispersion)와, 소포제/정포제/증점제/가교제/가교조제 및 분산제를 포함하여 구성된 첨가제와, 제오라이트(Zeolite) 분말을 각각 준비하여 일정 중량비율로 혼합하고, 재료가 안정화될 수 있도록 상온에서 1 ∼ 4시간 숙성시킨다. First, as described above, the preparation step (S10) of the composition for coating gloves includes water-soluble urea PUD (Urea Polyurethane Dispersion), which is a composition used for coating gloves, and a defoaming agent/foaming agent/thickener/crosslinking agent/crosslinking agent and dispersing agent. The additive and zeolite powder are prepared and mixed in a predetermined weight ratio, and aged at room temperature for 1 to 4 hours so that the material can be stabilized.
두번째, 표면코팅단계(S20)에서는 준비된 코팅용 조성물을 코팅하고자 하는 장갑의 표면에 도포하여 코팅한다.Second, in the surface coating step (S20), the prepared coating composition is applied to the surface of the glove to be coated and coated.
장갑의 코팅은 PUD합성수지 및 제오라이트(Zeolite)를 포함하는 코팅용 조성물이 장갑 내피로 함침 되는 과정으로서 편직된 장갑을 몰드에 끼우고 몰드를 상기 코팅용 조성물에 디핑(dipping)하고, 상기 몰드를 상하 방향으로 유동시킴과 동시에 몰드를 회전시켜 장갑의 회전운동에 의해 균일한 두께의 코팅층을 형성시킨다.Glove coating is a process in which a coating composition containing PUD synthetic resin and zeolite is impregnated with the glove inner skin. The knitted glove is put in a mold, the mold is dipping into the coating composition, and the mold is moved up and down. At the same time, the mold is rotated while flowing in the direction to form a coating layer of uniform thickness by the rotational movement of the glove.
특히, 본 발명은 입자의 크기가 큰 제오라이트의 특성상 코팅용 조성물의 함침시 제오라이트 사이의 공극에 의해 완전 밀폐가 되지 않고, 공기 및 땀의 미세분자는 통과하면서, 수분의 침투는 차단하는 코팅층이 형성됨에 그 기술적 특이성이 있다.In particular, in the present invention, due to the nature of zeolite having large particle size, when impregnating the coating composition, it is not completely sealed by the voids between the zeolite, and a coating layer is formed that blocks the penetration of moisture while passing fine molecules of air and sweat. has its technical specificity.
세번째, 장갑에 코팅된 조성물의 응고 및 경화단계(S30)는 장갑 표면에 흡수된 코팅용 조성물이 장갑에 부착되도록 공기 중에서 코팅용 조성물을 응고시켜 코팅층을 형성시킨다.Third, in the step of coagulating and curing the composition coated on the glove (S30), the coating composition is solidified in the air so that the coating composition absorbed on the glove surface is attached to the glove to form a coating layer.
이때, 종래 코팅장갑에서 물에서 실시되는 응고단계와 달리, 본 발명은 수용성 수지를 사용하므로 100℃ 이상의 고온 공기 중에서 실시되어야 하며, 100∼150℃에서 응고시키는 것이 바람직하다. At this time, unlike the coagulation step carried out in water in the conventional coating gloves, the present invention uses a water-soluble resin, so it should be carried out in high temperature air of 100 ° C. or higher, and it is preferable to solidify at 100 to 150 ° C.
또한, 본 발명에서 수용성 우레아 PUD(Urea Polyurethane Dispersion)가 사용되므로, 1차적으로 응고제(binder)가 응고 매개체로 작용하고 2차 응고는 경화공정에서 이루어지게 되는데, 이러한 과정에서 응고제에 의해 수용성우레아 PUD(polyurea dispersion) 수지 와 장갑 내피와의 이온결합이 동시에 이루어진다.In addition, since water-soluble urea PUD (Urea Polyurethane Dispersion) is used in the present invention, a binder primarily acts as a coagulation medium and secondary coagulation is performed in the curing process.
