The present invention relates to a synthetic rubber latex resin composition and a cotton glove coated with the same, and more particularly to a latex resin composition comprising a synthetic rubber latex as a main component and an acrylic emulsion and sodium polyacrylate as a thickening agent. In the present invention, since the acrylic emulsion having a high viscosity has a larger particle size and a longer molecular length by sodium polyacrylate, the synthetic rubber latex is prevented from penetrating between cotton fabrics when coated on cotton gloves, and a separate waterproofing agent or water repellent agent A latex coated cotton glove capable of evenly satisfying excellent sweat absorbability, oil resistance, gripability, flexibility and the like can be easily and easily produced without pretreatment with a coagulant.
Description
본 발명은 합성고무 라텍스 수지 조성물 및 이것이 코팅된 면장갑에 대한 것으로, 특히 면 장갑에 코팅하는 경우 면 직물 사이로 합성고무 라텍스가 스며들지 않으면서, 별도의 방수제나 발수제(응고제)에 의한 전처리 코팅 없이도, 우수한 땀 흡수성과, 내유성, 그립성, 굴곡성 등을 고르게 만족시킬 수 있는 라텍스 코팅 면 장갑을 간단하고 용이하게 제조할 수 있는 것이다.
The present invention relates to a synthetic rubber latex resin composition and a cotton glove coated with the synthetic rubber latex resin composition, and more particularly, to a cotton glove coated with synthetic rubber latex resin composition and cotton glove coated with the synthetic rubber latex resin composition and cotton glove coated with the synthetic rubber latex resin composition, It is possible to easily and easily produce a latex coated cotton glove which can satisfactorily satisfy superior sweat absorbability, oil resistance, gripability, flexibility and the like.
일반적으로 장업용 장갑에는 면으로 된 장갑과 나일론으로 된 장갑이 주종을 이루고 있다.In general, business gloves consist of cotton gloves and nylon gloves.
상기 면으로 된 장갑은 장갑의 재질이 면으로 직조되어 있기 때문에 장갑의 바닥면이나 손가락부에 수지를 코팅할 경우 수지가 면에 잘 묻음으로서 용이하게 코팅할수가 있으나 장갑이 면으로 된 특성으로 인하여 장갑을 이루고있는 면과 코팅부가 두껍고 투박하며, 이로 인하여 장갑을 끼고 물건을 집으로 경우 감각을 느낄 수가 없는 문제점이 있었다. 또한, 면에 수지가 코팅된 면장갑은 수지가 견고하기 때문에 장갑을 장기간 착용할 경우 손에 통증을 느끼게 됨으로서 작업자가 장갑의 착용을 기피하게 되는 단점이 있으며 이로 인하여 작업자가 맨손으로 작업을 하게 됨으로서 미끄럼이 잘생되어 안전사고가 일어나게 되는 단점이 있으며, 장갑의 사용을 기피함으로서 손이 트거나 사고가 일어 날 경우 작업자가 크게 다치게 되는 문제점이 있었다. 그리고, 면으로 된 장갑은 장갑을 직조할때 실이 굵으므로 인하여 직조시 장갑에 형성되는 실과 실사이의 간격이 크므로 보기가 흉한 단점이 있으며, 이로 인하여 면 장갑에 수지를 코팅할 경우 미관상 보기가 흉한 문제점이 있었다.Since the glove made of the above-mentioned face is woven with the surface of the glove, when the resin is coated on the bottom face or the finger portion of the glove, the resin can be easily coated because it is easily coated on the face. There is a problem that the face and the coating part forming the gloves are thick and tough, and the sense of feeling can not be felt when the object is put on the glove with the glove. In addition, the cotton gloves coated with resin on the face have a disadvantage that the workers feel pain in the hands when wearing the gloves for a long period of time because the resin is robust, thereby avoiding wearing of the gloves. As a result, There is a disadvantage that a safety accident occurs, and there is a problem that a worker is severely injured when a hand or an accident occurs by avoiding the use of gloves. In addition, the cotton gloves have a disadvantage in that the gap between the yarn and the yarn formed on the gloves is large due to the thick yarn when weaving the gloves, and therefore, when the resin is coated on the cotton gloves, There was a nasty problem.
또한, 나일론 장갑을 사용할 경우 나일론 자체가 미끄러운 재질이기 때문에 작업용으로 사용하기에는 곤란한 문제점이 있었다. 상기와 같은 문제점을 해결하기 위하여 나일론 장갑에 수지를 코팅할 경우 나일론의 미끄러운 성질에 의하여 수지가 묻지 않아 코팅이 되지 않는 단점이 있었다. 상기와 같이 종래에는 나일론의 장갑은 미끄러운 성질로 인하여 작업용으로는 사용하지 않게 되는 단점이 있으며, 이로 인하여 각종 행사장에서 일회용으로 착용하는 것으로 만족하여야 하므로서 고가의 장갑을 낭비하게 되는 문제점이 있었다.
Further, when nylon gloves are used, nylon itself is a slippery material, so that it is difficult to use it as a workpiece. When the resin is coated on the nylon glove to solve the above-mentioned problem, there is a drawback that the resin is not coated due to the slippery nature of the nylon and the coating is not performed. As described above, conventionally, the nylon glove is disadvantageous in that it is not used for a work because of its slippery nature, and therefore it is required to be worn as disposable at various events so that expensive gloves are wasted.
한편, 종래의 라텍스 코팅 장갑에는 천연 라텍스(natural latex)가 주로 사용되었는 데, 천연 라텍스에 함유된 단백질은 일부 사용자에게 통증이나 발진 등의 알러지 반응을 일으키는 문제점이 있었다. 그리고, 천연 라텍스는 원산지에 따라 물성이 달라 품질이 균일하지 않고, 최근 고무나무의 재배면적 감소로 인해 가격이 급등하고 있다. 또한, 천연 고무 라텍스는 장갑에 코팅되더라도 기름에 의해 쉽게 녹아내리고, 물체를 잡았을 때 매우 미끄러워서 그립성이 없기 때문에, 작업 능률이 떨어지고 일회용으로 사용하고 버려야하는 문제점이 있었다.On the other hand, natural latex is mainly used for conventional latex-coated gloves. Proteins contained in natural latex have a problem that some users cause allergic reaction such as pain and rash. In addition, the quality of natural latex is not uniform due to the different properties depending on the place of origin, and the price has soared due to the recent decrease in the cultivation area of the rubber tree. Further, the natural rubber latex is easily melted by oil even when it is coated on the glove, and when the object is gripped, it is very slippery and there is no grip, so that the work efficiency is lowered and it is used for disposable use.
이러한 단점을 보완하기 위하여, 합성고무로서 내유성인 니트릴 부타디엔 고무(NBR: nitrilebutadiene rubber) 라텍스를 코팅하기도 하지만, 물 세척이 없는 건식 타입으로 코팅할 경우 면장갑 내피 사이로 NBR LATEX가 침투되는 특수성 때문에 제품화할 수가 없었다. In order to compensate for these drawbacks, nitrile butadiene rubber latex (NBR) may be coated as a synthetic rubber, but when coated with a dry type without water washing, the NBR LATEX penetrates into the inner side of the armor There was no.

본 발명은 라텍스 수지 조성물에 대한 것으로, 주로 면이나 또는 나일론 등으로 이루어진 장갑에 코팅용으로 사용되는 것이며, 바람직하게는 면으로 이루어진 면 장갑 코팅용으로 적합한 것이다. The present invention relates to a latex resin composition, which is mainly used for coating on a glove made of cotton, nylon or the like, and is preferably suitable for coating cotton gloves made of cotton.
본 발명에 따른 라텍스 수지 조성물은 기본적으로 합성고무 라텍스를 주성분으로 한다. 상기 주성분으로 하는 것은 조성물 전체에서 상기 합성고무 라텍스가 절반 이상, 즉 50%이상 함유되는 것을 의미한다. 종래에 장갑용 코팅 조성물로서 사용되던 천연 고무 라텍스는 장갑에 코팅되더라도 기름에 의해 쉽게 녹아내리고, 물체를 잡았을 때 매우 미끄러워서 그립성이 없다는 단점이 있지만, 본 발명에 따른 라텍스 수지 조성물은 합성고무 라텍스를 기본 베이스 성분으로 함으로써 우수한 내유성과 그립성을 가진다. 상기 합성고무 라텍스는 이 기술분야에 알려진 다양한 것을 모두 포함하고, 예를 들면 니트릴 부타디엔 고무(NBR: nitrilebutadiene rubber) 라텍스, 스티렌-부타디엔 라텍스(SB 라텍스), 스티렌-부타디엔 고무 라텍스(SBR latex) 등일 수 있으며, 그 중에서도 NBR 라텍스인 것이 더욱 바람직하다. The latex resin composition according to the present invention basically comprises a synthetic rubber latex. The above-mentioned main component means that the synthetic rubber latex is contained in an amount of not less than half, that is, not less than 50%, in the whole composition. The latex resin composition according to the present invention is a synthetic rubber latex which is used as a coating composition for a glove and has a disadvantage in that it is easily melted by oil even when it is coated on gloves and is very slippery when holding an object, By making it the base base component, it has excellent oil resistance and gripability. The synthetic rubber latex may include a variety of synthetic rubber latexes, such as nitrile butadiene rubber (NBR) latex, styrene-butadiene latex (SB latex), styrene-butadiene rubber latex Among them, NBR latex is more preferable.
특히, 본 발명에 따른 라텍스 수지 조성물은 합성고무 라텍스에 더하여, 점증제로서 아크릴 에멀젼과, 폴리아크릴산나트륨을 포함하는 것이 특징이다. 종래에 합성고무 라텍스를 면 장갑에 코팅하면, 면장갑 내피 사이로 NBR LATEX가 침투되어 제품화할 수가 없었다. 본 발명자는 합성고무 라텍스를 기본으로 하는 라텍스 수지 조성물에 있어서, 다양한 점증제와 첨가제들의 조합에 대하여 계속된 연구를 거듭한 결과, 점증제로서 아크릴 에멀젼과, 첨가제로서 폴리아크릴산나트륨을 함께 이용하면, 우수한 땀 흡수성과, 내유성, 그립성, 굴곡성 등을 고르게 만족시킬 수 있음을 확인한 후, 본 발명을 완성하였다. Particularly, the latex resin composition according to the present invention is characterized by comprising an acrylic emulsion and sodium polyacrylate as a thickening agent in addition to a synthetic rubber latex. Conventionally, when synthetic rubber latex is coated on cotton gloves, NBR LATEX penetrates into the inner surface of cotton gloves, making it impossible to commercialize. As a result of continuing research on various combinations of thickeners and additives in a latex resin composition based on a synthetic rubber latex, the present inventors have found that when an acrylic emulsion is used as a thickening agent and sodium polyacrylate is used together as an additive, The present inventors have completed the present invention after confirming that excellent sweat absorbability, oil resistance, gripability, flexibility and the like can be satisfactorily satisfied.
종래에 증점제는 도포되는 수지의 두께, 함침의 정도, 착색의 정도에 따라 점도를 조절 및 유지시키는 역할을 하는데, 일반적으로 수지의 두께는 용도별로 0.1~2.0mm 범위로 조절되도록 한다. 이때, 증점제로는 아크릴계 증점제, 아마이드계증점제, 우레탄계 증점제 및 셀룰로즈계 증점제 등이 많이 사용된다. Conventionally, the thickener has a function of controlling and maintaining the viscosity according to the thickness of the applied resin, the degree of impregnation, and the degree of coloring. Generally, the thickness of the resin is adjusted within the range of 0.1 to 2.0 mm for each application. At this time, as the thickening agent, acrylic type thickening agent, amide type thickening agent, urethane type thickening agent and cellulose type thickening agent are widely used.
본 발명자는 아크릴 에멀젼 점증제와 함께, 알긴산나트륨, 메틸셀룰로오스, 규산나트륨, PVA, 폴리아크릴산나트륨 및 벤토니트로 등의 다양한 조합에 대하여 실험을 해 보았으나, 후술하는 실시예에서 확인할 수 있는 바와 같이, 아크릴 에멀젼과 폴리아크릴산나트륨을 함께 이용하는 경우에만 전체적으로 우수한 효과를 얻을 수 있었다. The present inventors have experimented with various combinations of sodium alginate, methyl cellulose, sodium silicate, PVA, sodium polyacrylate, and bentonitro together with the acrylic emulsion thickener, but as can be seen in the following examples, Only when an acrylic emulsion and sodium polyacrylate were used together, an excellent effect was obtained as a whole.
이에 따라, 본 발명은 점증제로서 아크릴 에멀젼과, 폴리아크릴산나트륨을 함께 포함하는 것이 특징이고, 아마도 점성이 높은 아크릴 에멀젼이 폴리아크릴산나트륨에 의해 입자 크기가 커지고 분자길이도 길어짐으로써, 면 장갑에 코팅하는 경우 면 직물 사이로 합성고무 라텍스가 스며들지 않도록 해 주는 것으로 판단된다. 이를 통해, 본 발명은 별도의 방수제나 발수제(응고제)에 의한 전처리 코팅 없이도, 우수한 땀 흡수성과, 내유성, 그립성, 굴곡성 등을 고르게 만족시킬 수 있는 라텍스 코팅 면 장갑을 간단하고 용이하게 제조할 수 있는 효과가 있다. Accordingly, the present invention is characterized in that an acrylic emulsion and sodium polyacrylate are contained together as a thickening agent, and the acrylic emulsion having a high viscosity is thickened by the sodium polyacrylate and the molecular length is long, It is considered that the synthetic rubber latex does not permeate between cotton fabrics. Accordingly, the present invention can easily and easily produce a latex coated cotton glove which can satisfactorily satisfy superior sweat absorbability, oil resistance, gripability, flexibility and the like without pretreatment with a waterproofing agent or a water repellent agent There is an effect.

That is, in order to minimize the effect of adding the acrylic emulsion and sodium polyacrylate, the acrylic emulsion and the sodium polyacrylate are added to the synthetic rubber latex in an amount of 0.1 wt% based on 100 wt% Or more. In addition, when the acrylic emulsion and sodium polyacrylate are added in an excess amount, the properties (elasticity, flexibility, etc.) of the coating layer due to the synthetic rubber latex may be deteriorated. To prevent this, the acrylic emulsion and sodium polyacrylate It is preferably contained in an amount of 5.0 parts by weight or less based on 100 parts by weight of the synthetic rubber latex.
