산염기성 검지의 산업용 흡수포{DETECTING WIPER OF ACID AND ALKALINE CHEMICALS}DETECTING WIPER OF ACID AND ALKALINE CHEMICALS [0002]

본 발명은 산염기성 검지의 산업용 흡수포에 관한 것으로서, 더욱 상세하게는 각종 산업공정에서 사용되는 산 또는 염기성 화학물의 누출, 유출분을 흡수하는 흡수포의 개선에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an industrial absorbent foam of acid-basic detection, and more particularly, to an improvement of an absorbent foam that absorbs leakage or leakage of acid or basic chemicals used in various industrial processes.

본 발명은 본 출원인의 이전 출원인 특허출원 제 10-2015-0082835호(산염기성 화학물의 검지체)의 후속적인 발명으로서 선행기술의 기본적인 기술적 사상을 바탕으로 하여 그 사용용도를 더욱 구체화하고 효용성을 증대한 것에 관한 것이다.The present invention is based on the basic technical idea of the prior art as a succeeding invention of the applicant's earlier application, Patent Application No. 10-2015-0082835 (a gum of an acid-basic chemical) It is about one thing.

다양한 종류의 화공약품을 취급하는 산업현장에서 산 또는 염기성의 화학물을 사용하게 되고 공정상 불가불 산염기의 유출 또는 잔여분을 흡수하는 흡수포를 사용한다.In industrial sites dealing with various types of chemical agents, acid or basic chemicals are used, and in the process, absorbing bubbles are used to absorb the spillage or residue of unfilled bases.

흡수포는 흡수성이 높은 부직포를 주로 사용하나 일단 누출된 산 또는 염기를 흡수하여 폐기하는 경우, 흡수된 산이나 염기가 잔존하여 있게 된다.The absorbent blanks are mainly made of nonwoven fabric having a high absorbency, but once the absorbed acid or base is absorbed and discarded, the absorbed acid or base remains.

따라서 이러한 흡수포를 폐기하거나 방기하는 경우 서로 다른 산-염기가 반응하여 발열하여 화재가 유발되거나 독성의 가스를 발산하게 되거나, 사용자가 이를 알지 못하여 손으로 취급하는 경우 화학적인 화상을 입게 되는 등 다양한 형태의 환경위해요인이 되고 있다.특히, 강산,강염기들은 투명한 색상이어서 작업자가 사용후의 흡수포를 손으로 만지게 되어 화학화상을 입는 경우가 다발하고 있다.Therefore, when these absorbent blanks are discarded or discarded, different acid-base reacts to generate heat, causing a fire or emitting toxic gas, or when a user does not know this, they are exposed to chemical burn In particular, strong acids and strong bases are transparent colors, and the operator often touches the absorbent foam after use, so that the user often wears chemical burns.

따라서 일단 산 또는 염기를 흡수한 흡수포의 경우, 이를 작업자에게 고지하기 위한 수단이 강구될 필요가 대두되어왔고 종래로부터도 다양한 종류의 흡수포, 특히 산염기 흡수상태를 작업자에게 고지하기 위한 수단이 강구되어 왔다.Therefore, in the case of an absorbent fabric absorbing an acid or a base, there has been a need to provide a means for informing the operator of the absorbent fabric and a means for notifying the operator of various types of absorbent fabrics, particularly acid- Has been adopted.

특히 한국 특허 10-1501758호와 한국특허출원 제 10-2013-1501758호에서는 리트머스액을 환합한 수지를 부직포에 인쇄하여 건조한 것을 사용함으로서 흡수포의 색상으로 산염기를 검출하는 구성을 제시하고 있으나, 리트머스는 산염기의 색상의 변화가 명확하지 않아서 사용자가 이를 쉽게 인식하기 어렵다는 문제점을 가지고 있었다.In particular, Korean Patent No. 10-1501758 and Korean Patent Application No. 10-2013-1501758 disclose a configuration in which an acid salt group is detected by the color of the absorbent cloth by using a resin obtained by printing a litmus solution-containing resin on a nonwoven fabric and drying it, Has a problem that it is difficult for the user to recognize the change of the color of the acid base because it is not clear.

또한 수지로서 핫멜트를 사용함으로서 소수성을 가짐으로서 흡습성이 저하되는 문제점도 가지고 있었다.In addition, the use of hot melt as a resin has a problem of lowering hygroscopicity due to hydrophobicity.

이들 선원과 같이 구성하여 예시적으로 도시한 것이 도 1로서 산과 염기의 지시색이 불명함을 시각적으로 알 수 있다.As shown in FIG. 1, it is visually recognized that the indication colors of the acid and the base are unknown.

상기와 같은 종래의 문제점을 감안하여 본 발명의 산염기성 검지의 산업용 흡수포에서는, 산염기를 검출하는 지시색이 선명하여 작업자가 용이하게 이를 시각적으로 인식하여 폐기하게 함으로써 화학적인 위해요소를 사전에 제거할 수 있게하고,In view of the above-described conventional problems, in the industrial absorbent sheet of the present invention, since the instruction color for detecting the acid group is clear and the operator can visually recognize and discard the acid salt easily, To do this,

또한, 작업자의 인식이 문자로서 이를 지각하게 함으로써 색상변화에 따른 산염기에 대한 교육을 주지하지 않아도 되는 유용성을 가지게 한다.In addition, the perception of the operator as perceived by the character makes it useful to avoid teaching about the acid period due to color change.

이에 본 발명에서는 상술한 바와 같은 문제점을 해결하기 위하여 발명한 것으로서, 산업현장에서의 산, 염기성 화학물질을 시각적으로 구분하여 흡습,제거하기 위한 산염기성 검지의 산업용 흡수포를 구성함에 있어서,Accordingly, the present invention has been made to solve the above problems, and it is an object of the present invention to provide an industrial absorbent fabric for acid-base detection for visually separating and absorbing acid and basic chemicals in an industrial field,

본 발명의 산염기성 검지의 산업용 흡수포는 산,염기의 최적의 검지시약을 선택하고 그 선택된 검지시약을 최적의 방법으로 사용할 수 있는 흡수포의 형태를 제공하고자 한다.The industrial absorbent foam of the present invention for acid-base detection is intended to select an optimal detection reagent of an acid or a base and to provide a form of an absorbent foam in which the selected detection reagent can be used in an optimal manner.

본 발명의 산염기성 검지의 산업용 흡수포에 사용되는 검지시약은 시각적인 선명한 색상의 변화를 통하여 산와 염기를 동시에 검지가능한 시약을 선정하여야 하고 이 시약이 화학적으로 안정되고 인체에 무해하여야 한다.The detection reagent used in the acid-base detection industrial absorbent of the present invention should select a reagent capable of simultaneously detecting acid and base through visual and color change, and the reagent should be chemically stable and harmless to the human body.

[최적의 지시약의 선정][Selection of Optimum Indicator]

이러한 PH지시약을 찾은 바, 리트머스는 산에서는 적색으로 염기에서는 청색으로 변하나 색상이 연하므로 시인성이 좋지않아 사용이 어렵고, 티몰블루를 사용하는 것이 최적의 선택임을 알 수있다.When these PH indicators are found, litmus changes to red in acid and blue in base, but since it is soft in color, it is difficult to use because visibility is poor and Tymol blue is the best choice.

이는 도 2에서와 같은 지시색의 분포에서와 같이, PH2.8이하는 적색을 지시하고 PH8.5이상에서는 청색을 지시하여 가장 최적임을 알 수 있다.As shown in the distribution of the indicator color as shown in FIG. 2, it can be seen that PH 2.8 indicates the red color, and PH 8.5 indicates the blue color.

또한 티몰블루의 경우 암을 유발하는 등의 소인이 없어 인체에 무해하다.In addition, thymol blue is harmless to the human body because it does not cause cancer such as cancer.

더욱 바람직하게는 PH2.9 ~ 6.0 영역을 분명하게 표현하기 위해서 메틸레드(PH6.0이하는 적색,PH6.1이상은 황색)를 추가로 넣어서 사용함으로서 지시 PH 범위를 확정할 수 있다.More preferably, the indicated PH range can be determined by additionally using methyl red (red for PH6.0 or less and yellow for PH6.1 or more) in order to clearly express the PH2.9 to 6.0 region.

다른 지시약, 예를들면 리트머스시험지는 지시약 자체의 특성으로 인하여 검지 시인성이 저하되어 용이한 판단이 어렵고, 메틸옐로우는 발암물질로 분류되었고, 메틸오렌지는 유전자변이물질로 규정되어 사용할 수 없다.Another indicator, such as litmus paper is difficult to determine easy visibility detection due to the properties of the indicator itself is lowered, methyl yellow has been classified as a carcinogen, methyl orange can not be used is specified in transgenic material.

또한, 염기에서 청색을 띄는 PH지시약으로는 브로모티몰블루(BTB)는 중성인 물에서도 청색으로 변하므로 물이 묻은 경우에도 염기에 오염된 것으로 오인할 수 있고 물이 묻은 자리가 청색으로 오염되어 시각적으로 바람직하지 않은 즉, 중성에서 청색이어서 시인성이 떨어지고, 티몰프탈레인은 강한 염기에서는 몇분 후 퇴색되어 무색으로 변하여 염기에 오염된 순간은 인지되나 시간경과 시 인지되지 않아 적용이 불가능하다.In addition, as a PH indicator with a blue color in the base, bromothymol blue (BTB) turns blue even in neutral water, so even if water is added, it can be mistaken as contaminated with a base. Visually undesirable, that is, from neutral to blue, the visibility deteriorates, and thymolphthalein is discolored after a few minutes in strong bases and becomes colorless, and the moment of contamination with the base is recognized but not applicable over time.

상기하는 바와 같이, 티몰블루 단독 또는 메틸레드를 혼용하여 지시약(T)으로서 선정하고 이 지시약이 흡착되어 안정화되고 친수성을 가지도록 수지를 선정하여야 한다.As described above, thymol blue alone or methyl red is preferably used as the indicator (T), and the resin should be selected so that the indicator is adsorbed and stabilized and has hydrophilicity.

이를 안정화수지(S)라 하기로 한다. 안정화수지(S)는 친환경적인 에멀젼수지(폴리우레탄수지, 아크릴수지 등)나 알콜계수지(폴리우레탄수지,아크릴수지등)를 사용하고 수용성인 산,염기와 친화력을 올리기위해 친수성단량체(수산.카복실기,초산등)가 15-40mole %(15mole %미만은 친수성이 약해서 친수성인 산,염기와 친화력이 약해 PH지시약의 색상변화가 적으며 40mole%넘을 경우는 코팅면이 내수성이 약해서 수분에 의해 팽윤되어 검지수지층가 탈락됨)로 설정한다.This is referred to as a stabilizing resin (S). The stabilizing resin (S) uses an environmentally friendly emulsion resin (polyurethane resin, acrylic resin, etc.) or an alcohol-based resin (polyurethane resin, acrylic resin, etc.) and a hydrophilic monomer (a water-soluble monomer) to increase affinity with water- 15-40mole% (15mole% or less) is weak in hydrophilicity and weak affinity with hydrophilic acid and base, and color change of PH indicator is small. If it is more than 40mole%, the coating surface is weak in water resistance. The detection resin layer is swollen and the detection resin layer is removed).

만일, 수지에 친수성단량체가 없거나 15mole%미만인 경우는 수용성수지(폴리비닐알콜,폴리에틸렌비닐알콜등)를 4-10중량%를 혼합하여 구성한다.(4%미만은 친수성이 약해서 친수성인 산,염기와 친화력이 약해 PH지시약의 색상변화가 적으며 10%넘을 경우는 코팅면이 내수성이 약해서 수분에 의해 팽윤되어 검지수지층가 탈락됨).If the resin does not contain a hydrophilic monomer or is less than 15 mole%, it is composed of 4-10% by weight of a water-soluble resin (polyvinyl alcohol, polyethylene vinyl alcohol, etc.) mixed therein. (Less than 4% And the affinity is weak and the color change of the PH indicator is small, and when it exceeds 10%, the coated surface is weak in water resistance, swelling by moisture, and the detection resin layer is dropped).

상기와 같은 안정화수지(S)에 티몰블루를 혼합하고 PH범위에 따라서는 상술한 바와 같이 메틸레드를 추가적으로 혼합할 수 있다.Thymol blue may be mixed with the stabilizing resin (S), and methyl red may be further added as described above depending on the PH range.

[흡수포의 제작][Production of absorbing cloth]

(1) 본 발명의 산염기성 검지의 산업용 흡수포를 구성하기 위하여 상기의 검출제를 코팅액으로서 준비한다.(1) The above-mentioned detecting agent is prepared as a coating liquid in order to constitute an industrial absorbent sheet of an acid-basic detection of the present invention.

(2) 흡수모재(B)는 멜트블로운부직포를 기본으로 하여 구성하므로, 섬유의 직경이 머리카락 굵기의 1/00 에 해당하는 1 ~10μm 로 미세하여 모세관현상이 우수하고, 계면활성제에 침지하여 상기 흡수모재(B)를 친수화가공하여 흡수성을 부여한 것이다.(2) Since the absorbent base material (B) is constituted based on a meltblown nonwoven fabric, the diameter of the fibers is 1 to 10 탆 corresponding to 1/00 of the thickness of the hair and is excellent in capillary phenomenon and is immersed in the surfactant And the absorbent base material (B) is hydrophilized to impart absorbency.

(3) 계면활성제에 침지하여 흡수모재(B)를 친수화가공하고 흡수성을 부여하고,(3) immersing in a surfactant to hydrophilize and absorb the base material (B)

(4) 이 친수화가공된 흡수모재(B)의 앞뒤면에 위의 검출제를 공극률이 70~90% 정도로서 무늬 또는 글씨형태의 검출인덱스(I)를 사방연속으로 인쇄하는 것이 바람직하다.It is preferable to print the above detection agent on the front and back surfaces of the hydrophilic processed absorbent base material B with the detection index I of a pattern or a letter form in a four-sided continuous manner with a porosity of about 70 to 90%.

흡수모재(B)를 친수화가공하기 위하여 계면활성제에 침지하는 이유는 흡수모재(B)로서의 멜트블로운부직포는 소수성인 PP 재이므로 유(oily))흡착포로서는 바람직하나 친수성을 가지지 않기 때문에 친수성을 부여하여 광범위한 산염기화학물을 흡습하기 용이하게 하기 위한 것이다.The reason why the base material (B) is immersed in the surfactant for hydrophilizing is that the meltblown nonwoven fabric as the base material (B) is a hydrophobic PP material and therefore is preferable as an oil absorbing material. However, since it has no hydrophilic property, To facilitate absorption of a wide range of acid base chemicals.

(5) 검출인덱스(I)를 실크스크린 또는 그라비아인쇄로 인쇄하고 이를 100 ~ 140도로 검출제를 건조시켜 완성하게 된다. 멜트브라운부직포가 PP 소재이므로 고온에서의 건조는 바람직하지 않다.(5) The detection index (I) is printed by silk screen or gravure printing, and the detection agent is dried by 100 to 140 degrees. Since the melt-blown nonwoven fabric is a PP material, drying at a high temperature is not preferable.

도 3은 검출제로서 사방연속으로 산-염기 문자를 인쇄하여 건조한 상태로서 정상적인 상태에서는 아주 연한 황색을 띄게 된다.FIG. 3 shows a state in which the acid-base character is printed in a four-by-two succession as a detecting agent and dried, and in a normal state, it becomes very light yellow.

그러나 도 4에서와 같이 산,염기가 검출된 검출영역(A)의 경우의 지시상태에서는 문자가 인식되게 되어 작업자는 용이하게 산염기의 화학물이 흡수되어 있는 상태를 인지하게 되는 것이다.However, as shown in FIG. 4, characters are recognized in the indicated state in the case of the detection region A in which acid and base are detected, so that the operator easily perceives a state in which the acid chemical is absorbed.

도 5는 산-염기검출제를 문자가 아닌 격자형상(메쉬형상)으로 하여 인쇄한 상태에서 산, 염기를 하기와 같이 시행하여 검출된 상태를 도시하는 사진이고, 도 6은 섹차측정기로 색차값을 측정하는 상태를 도시한다.FIG. 5 is a photograph showing a state in which an acid and a base are detected in the following manner in the state that the acid-base detecting agent is printed in a lattice shape (mesh shape) instead of a character, As shown in Fig.

본 발명의 방법으로 제조된 산염기성 검지의 산업용 흡수포와 종래 발명에 의해 제조된 산염기성 검지의 산업용 흡수포를 50% 산과 40%수산화나트륨을 떨어뜨리고 색차측정기로 측정한 색차값(Lab)을 비교한 데이터 표1을 보면 색차값이 현저히 차이나는 것을 확인할 수 있다.The industrial absorbent cloth prepared by the method of the present invention and the industrial absorbent cloth prepared by the conventional method were dropped to 50% acid and 40% sodium hydroxide, and the color difference value (Lab) measured by the color difference meter was compared One data table shows that the color difference values are significantly different.
