Description
본 발명은 무기항균 담체 및 이를 포함한 폴리우레탄재에 관한 것으로서, 더욱 상세하게는 폴리우레탄 액상재와 함께 가소제, 첨가제 및 안료 등을 포함하는 액상의 폴리우레탄재에 제올라이트 또는 인산지르코늄 담체에 은, 아연 또는 구리 등의 무기계 금속염 용액을 첨가하여 이온교환시켜 제조한 무기계 항균 담체를 배합하여 제조하는 항균기능을 지닌 무기항균 담체 및 이를 포함한 폴리우레탄재에 관한 것이다.The present invention relates to an inorganic antibacterial carrier and a polyurethane material including the same, and more particularly, to a liquid polyurethane material containing a plasticizer, an additive, a pigment, etc. together with a polyurethane liquid material, to a zeolite or a zirconium phosphate carrier, to zinc and zinc. Or it relates to an inorganic antimicrobial carrier having an antimicrobial function prepared by combining an inorganic antibacterial carrier prepared by ion exchange by adding an inorganic metal salt solution such as copper, and a polyurethane material including the same.
일반적으로, 자동차에는 핸들이나 인슐레이터 폼 등 폴리우레탄(Polyurethane)으로 제작된 부분이 많다. 이렇게 일반적인 사람들의 접촉부위에 많이 사용되는 폴리우레탄 제품에는 별도의 항균기능이 없어 대기중의 수분이나 먼지 등에 의해 세균이나 곰팡이가 서식하게 된다. 그 결과 이들 세균이나 곰팡이가 서식하게 되면 부품 고유의 물성이 저하되거나 운전자를 비롯한 승객의 건강에 유해하게 되며 이들의 성장에 따른 유기물에 의해 냄새 등이 수반되므로 승차 환경이 매우 열악하게 된다. 특히, 범프 스토퍼(BUMP STOPPER) 같은 중요한 부품에 이들 곰팡이가 서식하게 되면 그 고유특성을 잃어 제품이 원래 견딜 수 있는하중을 견디지 못하고 균열이 생겨 차량 주행시 안전에 심각한 위험을 초래하게 되기도 한다.In general, there are many parts made of polyurethane (polyurethane), such as a handle or an insulator foam. Polyurethane products, which are frequently used in contact areas of ordinary people, do not have a separate antibacterial function, and bacteria or molds are inhabited by moisture or dust in the air. As a result, when these bacteria or molds are inhabited, the inherent physical properties of the parts are deteriorated or harmful to the health of passengers and passengers, and the odor is accompanied by organic materials according to their growth, and thus the riding environment becomes very poor. In particular, when these molds inhabit important parts such as bump stoppers, they lose their inherent properties, causing the product to not withstand the loads it can withstand, resulting in cracks and serious risks to safety.
따라서, 종래에는 이러한 세균이나 곰팡이를 제거하기 위하여 유기계 항균제가 주로 사용되어 왔으나, 이 유기계 항균제는 살균력이 강한 반면 휘발 및 분산 등이 되어 인체에 유해할 뿐만 아니라, 내성균을 발생시킬 수 있는 문제점과 유효 사용기간이 짧아 수시로 반복해주어야 하는 문제점이 있어 이를 해결할 필요성이 절실히 요구되는 실정이었다.Therefore, in the past, organic antimicrobial agents have been mainly used to remove such bacteria and fungi. However, the organic antimicrobial agents have strong bactericidal power, but are volatile and dispersed. Due to the short duration of use, there is a problem that needs to be repeated from time to time.
이에, 본 발명의 별명자는 상기와 같은 문제점을 해결하기 위하여 예의 노력한 결과, 무기계 항균 담체를 폴리우레탄재 제조시 함께 배합함으로써, 인체에 무해함은 물론 내성균도 발생시키지 않은 채 살균효과가 장기간 지속됨을 확인함으로써, 본 발명을 완성하였다.Thus, the nickname of the present invention, as a result of intensive efforts to solve the above problems, by combining together the inorganic antimicrobial carrier in the production of polyurethane material, it is harmless to the human body as well as the long-lasting sterilization effect without generating resistant bacteria By confirming, the present invention was completed.
결국, 본 발명의 주된 목적은 제올라이트 또는 인산지르코늄 담체에 무기계 금속염 용액을 첨가하여 이온교환시켜 제조하는 것을 특징으로 하는 무기계 항균 담체를 제공하는 데 있다.After all, the main object of the present invention is to provide an inorganic antimicrobial carrier, characterized in that the ion-exchange by preparing an inorganic metal salt solution to the zeolite or zirconium phosphate carrier.
또한, 본 발명의 또다른 목적은 상기의 무기계 항균 담체를 포함하는 폴리우레탄재를 제공하는 데 있다.In addition, another object of the present invention to provide a polyurethane material comprising the inorganic antibacterial carrier.
이하, 본 발명의 무기항균 담체 및 이를 포함한 폴리우레탄재에 대하여 보다 구체적으로 살펴보면 다음과 같다.Hereinafter, the inorganic antibacterial carrier of the present invention and the polyurethane material including the same will be described in more detail.
우선, 본 발명은 제올라이트 또는 인산지르코늄 담체 MFI(ZSM-5), MZr2(PO4)3에 대하여 무기계 금속염 용액 Ag, Zn, Cu를 포함하는 무기계 항균 담체에 관한 것이다.First, the present invention relates to an inorganic antimicrobial carrier comprising an inorganic metal salt solution Ag, Zn, Cu with respect to a zeolite or zirconium phosphate support MFI (ZSM-5), MZr 2 (PO 4 ) 3 .
이러한 무기계 항균담체는 제올라이트 또는 인산지르코늄 담체에 은, 아연 또는 구리 중에서 선택된 1종 이상을 결합시킨 것으로, 이들은 담체와 항균제 모두 금속염이므로 이온교환에 의한 결합이 가능하다. 따라서, 이들은 이온화된 금속염 상태로 하여 상호 이온교환시킨 후 이들만을 세척분리하여 건조시키면 분말 상태의 무기계 항균담체를 제조할 수 있게 된다. 이때, 항균제인 무기계 금속염의 함량은 항균효능을 결정하는 주요소로서 그 첨가량을 조절하여 항균활성을 조절한다. 이렇게 담체에 결합된 무기계 항균제인 금속염들은 공기중의 수분과 접촉하게 되면 이들 이온들이 촉매로 작용하게 되어 용존산소를 활성산소로 변화시키게 된다. 그 결과 발생되는 활성산소는 오존과 같이 강한 살균력을 가지고 있어 주변으로 확산되며 항균 살균작용을 나타내게 되는 것이다. 이러한 무기계 항균 금속염은 담체 제올라이트 또는 인산지로코늄에 대하여 Ag, Zn, Cu를 포함하는 것이 바람직하며, 상기 금속염이 아닌 다른 금속이 포함되면 인체에 유해한문제가 있다.The inorganic antimicrobial carrier is a combination of one or more selected from silver, zinc or copper with a zeolite or zirconium phosphate carrier. These carriers and the antimicrobial agent are metal salts, and thus can be bonded by ion exchange. Therefore, they are ionized metal salts, and after the ion exchange with each other, only washing them separated and dried, it is possible to produce a powder-based inorganic antimicrobial carrier. At this time, the content of the inorganic metal salt as an antimicrobial agent is to determine the antimicrobial effect as a control element to adjust the amount of antimicrobial activity. The metal salts, which are inorganic antimicrobial agents bound to the carrier, come into contact with moisture in the air, and these ions act as catalysts to convert dissolved oxygen into active oxygen. The resulting active oxygen has a strong bactericidal power like ozone and diffuses around and exhibits antibacterial bactericidal action. The inorganic antimicrobial metal salt preferably contains Ag, Zn, Cu relative to the carrier zeolite or zirconium phosphate, and when a metal other than the metal salt is included, there is a problem that is harmful to the human body.
또한, 본 발명은 이상에서 제조된 무기계 항균 담체 0.5 내지 5 중량%(w/w)를 포함하는 폴리우레탄재를 포함한다. 즉, 통상적으로 폴리우레탄을 제조하는 데 사용되는 폴리우레탄 액상재료와 함께 가소제와 첨가제 및 안료 등을 첨가 배합하여 통상의 방법에 따라 폴리우레탄을 제조한다.In addition, the present invention includes a polyurethane material containing 0.5 to 5% by weight (w / w) of the inorganic antimicrobial carrier prepared above. That is, a polyurethane is prepared according to a conventional method by adding and blending a plasticizer, an additive, a pigment, and the like together with a polyurethane liquid material used to prepare a polyurethane.
이하, 본 발명을 실시예 및 실험예 등에 의하여 더욱 상세히 설명하면 다음과 같은 바, 본 발명이 이들 실시예 및 실험예 등에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples and Experimental Examples and the like, but the present invention is not limited to these Examples and Experimental Examples.
