Description

항균효과를 갖는 멜라닌 화장판의 제조방법{Method of manufacturing a melanin decoration panel having an effect on anti-bacteria}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a melanin having an antibacterial effect,

본 발명은 항균효과를 갖는 멜라닌 화장판의 제조방법에 관한 것으로, 특히 항균효과가 우수한 제올라이트-Ag(zeolite Ag)항균제를 균일하게 분포시키면서도 표면투명층 코팅시 변색이 일어나지 않고 투명도를 그대로 유지하는 항균효과를 갖는 멜라닌화장판의 제조방법에 관한 것이다.The present invention relates to a method for producing a melanin having an antibacterial effect, and more particularly, to an antibacterial effect which maintains transparency without causing discoloration when a zeolite Ag antimicrobial agent having an excellent antimicrobial effect is evenly distributed, To a process for producing a melanin conversion plate.

최근 생활수준의 향상과 환경오염의 심화에 따라 위생에 대한 관심이 높아지면서, 바닥재나 벽지 등과 더불어 책상이나 씽크대 등에 사용되는 화장판에 대해서도 항균기능성의 요구가 점차 증대되고 있다.Background Art Recently, as the level of living and environmental pollution have increased, interest in hygiene has increased, and the demand for antimicrobial function has also been increasingly increasing for curtains used for desks and sinks, as well as flooring materials and wallpaper.

즉, 아파트, 맨션, 빌딩 및 병원 등 많은 사람들이 거주하는 생활공간이 세균이 번식할 수 있는 적정한 조건으로 되어 있어 곰팡이 및 박테리아 등의 세균에 의해 호흡기, 소화기 질환 등의 질병이 우려되고 있는 상황이므로, 생활에 밀접한 씽크대 등에 사용되는 화장판에 대해서도 항균기능이 요구되고 있는 것이다.In other words, since the living space in which many people reside, such as apartment buildings, condominiums, buildings, and hospitals, is in an appropriate condition for propagating bacteria, diseases such as respiratory or digestive diseases are a concern due to bacteria such as fungi and bacteria , Antimicrobial function is also required for the veneer used in the sink, which is close to life.

이러한 요구에 따라 본 출원인은 "항균효과를 갖는 비닐 바닥재"를 발명하여 특허출원 제 95-15942호로 출원한 바가 있는 데, 동 출원발명은 다수의 층으로 이루어지는 비닐화장판에서 적어도 하나이상의 층에 항균제를 그 구성층의 중량 대비 0.1 - 10중량% 투입하여 항균작용을 하도록 한 것으로서, 일부 섬유제품에는 항균효과를 갖는 것이 있었지만 바닥재에는 전혀 없었던 당시의 상황에 비추어 볼 때 상당히 획기적인 것이었다.In accordance with this demand, the applicant of the present invention invented "a vinyl flooring material having an antibacterial effect" and filed a patent application No. 95-15942. In this invention, a vinyl chloride laminate comprising a plurality of layers is coated with at least one layer of an antimicrobial agent 0.1 to 10% by weight based on the weight of the constituent layer, so that the antimicrobial effect is obtained. Although some fiber products have antimicrobial effect, they were quite remarkable in view of the situation at the time when they were not present in the floor material.

그런데 상기한 본 출원인의 종래 발명에서는 항균제로 유기계 및 무기계가 모두 사용되었지만 내열성, 무독성 및 항균효과의 지속성 등의 측면에서 제올라이트-Ag항균제가 바람직한 것으로 사용되었는 바, 이 무기항균제는 지속성을 가지는 반면 마이그레이션이 없어 멜라닌의 제품의 구조상 화장판의 설치시 세균과의 접촉이 가장많은 표면층에 적용할 때 원재료 자체가 금속이온으로 구성되어 있기 때문에 비중이 상대적으로 유기재료에 비해 커서 공정상 침전문제가 발생되고, 또한 항균제를 균일하게 분포시키기 어려우며, 특히 표면층에 적용하는 경우 변색이 일어나고 투명도가 저하되는 문제점이 있었다.However, in the above-mentioned inventions of the present applicant, both organic and inorganic antibacterial agents have been used, but zeolite-Ag antimicrobial agents are preferably used in terms of heat resistance, non-toxicity and persistence of antibacterial effect. , The melanin product is structurally superior to the organic material because the raw material itself is composed of metal ions when it is applied to the surface layer having the greatest contact with bacteria in the structure of the melanin product. , And it is difficult to uniformly distribute the antimicrobial agent. In particular, when applied to a surface layer, discoloration occurs and transparency is lowered.

특히 멜라닌 화장판과 같은 패턴의 제품은 표면의 투명성이 우수하고 색상변화가 없게 되는 것이 제품의 품질에 중요한 요소이다.In particular, products with the same pattern as the melanin veneer have an excellent transparency on the surface and no color change is an important factor in the quality of the product.

따라서 종래의 제올라이트-Ag와 같은 무기항균제의 공정상 문제점을 개선하기 위해 본 출원인은 "항균효과를 갖는 화장판 및 그 제조방법"을 발명하여 특허출원 제 96-6691호로 출원한 바가 있는 데, 동 출원발명은 다수의 층으로 이루어지는 멜라닌 화장판의 적어도 하나이상의 층에 유기계항균제를 0.1 - 5중량%를 투입하여 항균작용을 하도록 한 것으로서, 항균제로 사용된 유기계항균제가 수지와의 분산성이 우수하고 표면층의 투명도가 유지되는 화장판을 제공함과 더불어 장시간 작업시에도 침적하는 문제가 발생하지 않는 잇점이 있었지만 무기항균제에 비해 열 안정성이 낮고 지속성도 단기적인 물성상의 취약성을 가지고 있을 뿐만아니라 인체에 해로운 독성 때문에 그 사용범위가 한정되는 문제점이 있었다.Therefore, in order to solve the problems in the process of inorganic antibacterial agents such as the conventional zeolite-Ag, the present applicant has filed a patent application No. 96-6691 with the invention of "a brightening plate having an antibacterial effect and a manufacturing method thereof" The present invention is directed to an antibacterial effect by introducing 0.1 to 5% by weight of an organic antimicrobial agent into at least one layer of a multilayer melanin comprising multiple layers, wherein the organic antibacterial agent used as an antimicrobial agent is excellent in dispersibility with a resin It has the advantage of providing a veneer which maintains the transparency of the surface layer and does not cause deposition problems even during long working, but it has low thermal stability compared to inorganic antibacterial agents, has persistence and short-term physical property vulnerability, The use range thereof is limited.

따라서 상기 유기항균제에 비해 열안정성이 높고, 지속성도 장기적이면서 인체에 무해한 무기항균제를 사용하는 것이 바람직나 이들 무기항균제를 멜라닌 화장판에 적용시 최대약점인 표면투명층 제조공정중에 침적이 발생하게 되어 이에 따라 수지에 고르게 분산되지 않는 것과 변색이 최대의 문제점으로 대두되는 바, 이에 본 발명은 상기한 문제점을 해결하기 위한 것으로, 지속성과 고온안정성이 우수하면서도 인체에 해로운 독성이 없는 금속이온인 무기항균제가 장시간의 공정작업중에도 침적되지않으면서 수지에 고르게 분산되면서 표면층의 투명도가 유지될 수 있는 항균효과를 갖는 멜라닌 화장판의 제조방법을 제공하는 데 그 목적이 있다.Therefore, it is preferable to use an inorganic antimicrobial agent which is high in thermal stability and long-lasting and harmless to the human body as compared with the organic antimicrobial agent. When the inorganic antibacterial agent is applied to a melaninization plate, In order to solve the above-mentioned problems, the present invention provides an inorganic antibacterial agent which is a metal ion which is excellent in persistence and high temperature stability and has no harmful toxicity to human body And it is an object of the present invention to provide a method for producing a melanin converting plate having an antimicrobial effect capable of maintaining transparency of a surface layer while being uniformly dispersed in a resin without immersion even during a long process operation.

상기한 본 발명의 목적인 항균효과를 갖는 멜라닌 화장판의 제조방법은,무기항균제의 평균 입도를 2 - 3㎛로 제한하고, 특히 입도분포도 0.5 - 4㎛의 범위내에 제한하게 되는 것을 특징으로 한다.The method for producing an antimicrobial melanin having an antibacterial effect for the purpose of the present invention described above is characterized in that the average particle size of the inorganic antibacterial agent is limited to 2 - 3 탆 and the particle size distribution is limited to a range of 0.5 - 4 탆.

이러한 입도분포를 가지는 무기항균제를 수지중량 대비 0.1- 5중량% 바람직하게는 0.3 - 3중량%정도 투입하고, 이 무기항균제를 수지에 고르게 분산시키기 위해 소정의 분산제를 항균제 중량대비 0.1 - 2중량%이하, 바람직하게는 0.1- 0.5중량%투입한다.0.1 to 5% by weight, preferably 0.3 to 3% by weight, of the inorganic antibacterial agent having such a particle size distribution is added to the resin. To disperse the inorganic antibacterial agent evenly in the resin, a predetermined dispersant is added in an amount of 0.1 to 2% By weight, preferably 0.1 to 0.5% by weight.

이하, 본 발명을 첨부한 예시도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 일반적인 화장판의 일례를 나타내는 개략적인 단면도로서 이러한 화장판의 제조방법은 표면지를 제 1 함침용 수지에 함침시켜 형성된 표면층(3), 인쇄지를 제 2 함침용 수지에 함침시켜 형성된 인쇄층(2) 및 이면지를 제 3 인쇄층에 함침시켜 형성된 이면층(1)으로 이루어지게 되어 있다.Fig. 1 is a schematic cross-sectional view showing an example of a general laminating board. This manufacturing method of laminating board comprises a surface layer 3 formed by impregnating a surface paper with a first impregnating resin, a printing layer 3 formed by impregnating a printing paper with a second impregnating resin (2) and a backside layer (1) formed by impregnating the backside paper on the third printing layer.

도 2는 본 발명의 제조방법에 따라 무기항균제를 사용한 화장판의 일실시예를 나타내는 개략적인 단면도로서, 상기 표면층(3)에 무기항균제(4)가 고르게 분산되어 있다.FIG. 2 is a schematic cross-sectional view showing one embodiment of a laminating board using an inorganic antibacterial agent according to the production method of the present invention, wherein the inorganic antibacterial agent 4 is evenly dispersed in the surface layer 3.

그러나 표면층(3)에 제올라이트-Ag 항균제와 같은 무기항균제를 그대로 투입하게 되면, 비중이 큰 금속이온입자들이 제조공정중에 침적되면서 수지에 고르게 분산되지 않게 되므로 상기 제올라이트-Ag의 입도분포를 미세하게 하므로써 수지중에 고르게 분산시킬 수 있으나, 이때 상기 입도분포를 너무 미세하게 하면 제올라이트-Ag의 취급이 불편하게 되어 제조공정에 어려움이 있어 입도분포를 평균입도 2 - 3㎛로 제한하고, 이때 특히 입도분포도 0.5 - 4㎛의 범위내에서 제한하였다.However, when an inorganic antibacterial agent such as a zeolite-Ag antimicrobial agent is directly introduced into the surface layer 3, the metal ion particles having a large specific gravity are immersed in the resin during the production process and are not uniformly dispersed in the resin. Thus, the particle size distribution of the zeolite- However, if the particle size distribution is too fine, handling of the zeolite-Ag becomes inconvenient, which makes it difficult to carry out the production process. Therefore, the particle size distribution is limited to an average particle size of 2-3 mu m, - 4 [mu] m.

이와같이 상기한 입도분포를 가지는 제올라이트-Ag의 함량은 각층을 제조하기 위해 사용되는 함침용 수지의 중량 대비 0.1- 5중량%, 더욱 바람직하게는 0.3 - 3중량%정도이다.The content of the zeolite-Ag having the above-described particle size distribution is about 0.1 to 5% by weight, more preferably about 0.3 to 3% by weight, based on the weight of the impregnating resin used for producing each layer.

예를 들어 표면층(3)에만 제올라이트-Ag를 포함시키는 경우에는 표면지를 함침시킬 제 3 함침용 수지(대개 멜라닌 수지가 사용됨)의 중량대비로 상술한 중량% 만큼의 항균제가 포함되도록 하면되는 것이다.For example, when the zeolite-Ag is included only in the surface layer 3, the above-mentioned weight% of the antimicrobial agent should be included relative to the weight of the third impregnation resin to be impregnated with the surface paper (usually melanin resin is used).

이때 상기 제올라이트-Ag의 수지에 대한 분산성을 더욱 좋게 하기 위하여 소정의 분산제를 투입되는 것이 바람직한 바, 분산제의 함량은 제올라이트-Ag의 중량 대비 0.1 - 2중량%, 바람직하게는 0.1- 0.5중량%정도이다.In order to improve the dispersibility of the zeolite-Ag to the resin, it is preferable to add a predetermined dispersing agent. The content of the dispersing agent is 0.1 to 2% by weight, preferably 0.1 to 0.5% by weight, based on the weight of the zeolite- Respectively.

도 3을 참조하여 본 발명에 따른 화장판 제조방법을 설명하면, 이면지, 인쇄지 및 표면지를 각각 제 1 함침용 수지, 제 2 함침용 수지 및 제 3 함침용 수지에 각각 함침시키는 단계, 이들을 경화시켜 각각 이면층, 인쇄층 및 표면층을 형성하는 단계, 및 각층을 일체로 프레스가공하는 단계를 포함하는 화장판의 제조방법에 있어서, 상기 함침용수지의 함침단계전에 제 1 함침용수지, 제 2 함침용수지 및 제 3 함침용수지 중 어느 하나 혹은 둘이상에 평균입도가 2 - 3㎛, 입자의 크기가 0.5 - 4㎛범위를 가지는 입도분포의 무기항균제를 투입하는 단계를 더포함하게 있다.Referring to FIG. 3, the method for producing a green sheet according to the present invention comprises the steps of impregnating the first paper impregnation resin, the second impregnation resin and the third impregnation resin, respectively, Forming a back layer, a printing layer, and a surface layer, and pressing each layer integrally, the method comprising the steps of: preparing a first impregnation resin before impregnating the impregnation resin; Impregnating resin, and third impregnating resin to an inorganic antibacterial agent having an average particle size of 2 - 3 탆 and a particle size of 0.5 - 4 탆.

이때 상기한 입도분포를 가지는 무기항균제의 함량은 각층을 제조하기 위해 사용되는 함침용 수지의 중량 대비 0.1- 5중량%, 더욱 바람직하게는 0.3 - 3중량%정도이다.At this time, the content of the inorganic antibacterial agent having the above-mentioned particle size distribution is about 0.1 to 5% by weight, more preferably about 0.3 to 3% by weight, based on the weight of the impregnating resin used for producing each layer.

또한, 상기 무기항균제의 수지에 대한 분산성을 더욱 좋게 하기 위하여 교반기를 이용하여 골고루 분산시키고, 소정의 분산제를 투입되는 것이 바람직한 바, 분산제의 함량은 제올라이트-Ag의 중량 대비 0.1 - 2중량%, 바람직하게는 0.1- 0.5중량%정도이다.In order to further improve the dispersibility of the inorganic antibacterial agent with respect to the resin, it is preferable to disperse the dispersion uniformly using a stirrer and to introduce a predetermined dispersant. The content of the dispersant is preferably 0.1 to 2% by weight based on the weight of the zeolite- Preferably about 0.1 to 0.5% by weight.

여기서 상기 분산제를 사용하지 않을 경우 무기항균제가 수지중에 균일하게 분포하지 않게 되어 제조공정중에 바닦에 침적하므로써 항균제가 표면지 내에 균일하게 함침되지 않아 일정한 항균력을 유지할 수 없으며, 표면층이 색상변화를 일으킨다.When the dispersant is not used, the inorganic antimicrobial agent is not uniformly distributed in the resin, so that the antimicrobial agent is not uniformly impregnated in the surface paper by immersing the antimicrobial agent in the basin during the manufacturing process, so that a certain antimicrobial activity can not be maintained.

본 발명의 항균효과를 갖는 화장판의 제조방법에 따라 제조된 화장판의 항균력을 아래 표1에 나타내었다.Table 1 below shows the antibacterial activity of the chewing gum prepared according to the method for producing the chewing gum having the antimicrobial effect of the present invention.

상기 시험조건은 시험균액을 25℃에서 24시간 정치 배양한 후 균수를 측정한 것이고, 사용한 공시 균주는 대장균(Escherichia Coil)이다.The test conditions were that the test strain was allowed to stand at 25 ° C for 24 hours and the number of bacteria was measured. The used strain was Escherichia coil.

이와같이 본 발명의 화장판 제조방법은 함침용 수지와 분산성이 우수한 입도분포의 무기항균제를 사용하고, 또한 소정의 분산제를 사용하므로써 종래의 금속이온계 항균제를 사용하는 데 비해 항균제의 침적문제, 분산성의 저하문제등이 현저하게 줄어들었다.As described above, the present invention provides a method for producing a curled sheet, which comprises using an inorganic antibacterial agent having a particle size distribution excellent in impregnation resistance and dispersibility, and using a predetermined dispersing agent as compared with the conventional metal ion type antibacterial agent, And the problem of degradation of sexuality.
