Definitions
- the present invention relates to an eco-friendly sheet and a manufacturing method thereof, and more particularly, to an eco-friendly sheet using polyurethane and a manufacturing method thereof.
- a general sheet means various materials and patterns, as well as flame retardancy and durability, and a sticker-type finishing material formed by emphasizing the speed and convenience of construction, which is usually made of PVC as a main component. to be.
- the seat is relatively thick, and the surface can be processed by embossing, and is used in various places such as fashion, leather and household goods. Recently, it is produced in various forms such as flame-retardant-treated flame-retardant sheets or flame-retardant films.
- the existing sheet is manufactured by using PVC (Poly Vinyl Chloride) as its main component due to its excellent processability.
- PVC Poly Vinyl Chloride
- interior sheet manufactured using an eco-friendly plasticizer as a pre-registered open technology includes a PVC foam layer formed using an eco-friendly plasticizer synthesized by the reaction of citric acid derived from nature and two or more alcohols. Features interior seats.
- the previously registered public technology is, in order to prevent harm to the human body due to the harmful effects of phthalate-based plasticizers, for example, the use of phthalate-based plasticizers that are prescribed as endocrine system obstacles in regions such as Japan and the United States, It is only a replacement of the component material of the plasticizer with an eco-friendly plasticizer, and the main component for manufacturing the sheet is to use the same PVC ((Poly Vinyl Chloride)) as it is, therefore, an unexpected fire or interior seat In the case of incineration for disposal, problems due to the emission of gases and harmful substances that are harmful to the human body still exist.
- PVC Poly Vinyl Chloride
- the pre-registration technology devised by the present inventor forms an interior sheet using olefin-based polypropylene film paper, and prevents the release of toxic gases and harmful substances during the incineration operation of the sheet for fire or disposal. do it with
- the eco-friendly decorative interior sheet pre-registered by the inventor of the present invention prevents environmental pollution by blocking the discharge of harmful gases and harmful substances during the incineration operation of the interior sheet for fire or disposal. Although it exhibits a very excellent function in the context of daily use, additional functions that can help the user's body or the surrounding environment other than the simple characteristics of an eco-friendly technology product cannot be expected at all.
- An object of the present invention is to provide an eco-friendly sheet and a manufacturing method thereof, which can solve the above-described problems of "a method for manufacturing an eco-friendly decorative interior sheet and its interior sheet" registered in the earlier application by the inventor of the present invention.
- an object of the present invention is to provide an eco-friendly sheet that effectively eradicates various harmful bacteria inhabiting the sheet construction site and a manufacturing method thereof.
- an object of the present invention is to provide an eco-friendly sheet and a manufacturing method thereof that can safely shield harmful electromagnetic waves generated from the construction site to help the user's human health.
- an object of the present invention is to provide an eco-friendly sheet and a method for manufacturing the same using polyurethane without limiting the raw material of the film paper to polypropylene in order to increase usability.
- An eco-friendly sheet for solving the above-described problems, a surface sheet member composed of a first polyurethane film paper; and a back sheet member laminated on the lower surface of the top sheet member and composed of a second polyurethane film paper
- the first polyurethane film paper includes: a pair of first random polyurethane resin layers; a first homo polyurethane base layer disposed between the pair of first random polyurethane resin layers

Description
본 발명은 친환경 시트 및 그 제조 방법에 관한 것으로, 보다 상세하게는 폴리우레탄을 이용한 친환경 시트 및 그 제조 방법에 관한 것이다.The present invention relates to an eco-friendly sheet and a manufacturing method thereof, and more particularly, to an eco-friendly sheet using polyurethane and a manufacturing method thereof.
일반적인 시트라 함은, 다양한 재질과 패턴은 물론, 난연성과 내구성, 그리고, 시공의 신속성과 편리성을 부각시켜 형성한 스티커 형태의 마감재 등을 의미하는 것으로, 이는 통상 PVC를 주성분으로 하여 이루어짐이 일반적이다.A general sheet means various materials and patterns, as well as flame retardancy and durability, and a sticker-type finishing material formed by emphasizing the speed and convenience of construction, which is usually made of PVC as a main component. to be.
시트는 비교적 두께가 두툼하고 표면은 엠보싱으로 가공될 수 있으며, 패션, 가죽 및 생활 잡화 등 다양한 곳에 사용된다. 최근에는 난연처리가 된 방염시트 또는 방염필름 등 다양한 형태로 생산된다.The seat is relatively thick, and the surface can be processed by embossing, and is used in various places such as fashion, leather and household goods. Recently, it is produced in various forms such as flame-retardant-treated flame-retardant sheets or flame-retardant films.
하지만, 전술한 바와 같은, 기존 시트는 가공성이 우수다는 이유로, 그 주성분을 PVC((Poly VinylChloride)로 하여 제조한 것인바, 따라서, 이러한 PVC는 재질특성상 화재나 소각시 인체에 매우 유해한 물질, 예컨대, 각종 발암물질은 물론 환경 호르몬 등이 다량 함유된 유독가스 및 유독물질을 배출하며 인체건강과 자연환경을 매우 심각하게 훼손하는 문제점이 있다.However, as described above, the existing sheet is manufactured by using PVC (Poly Vinyl Chloride) as its main component due to its excellent processability. , various carcinogens, as well as toxic gases and toxic substances containing a large amount of environmental hormones, have a problem of seriously damaging human health and the natural environment.
한편, 전술한 일부 문제점을 해결하기 위한 방안으로, 종래 시트 중 인테리어시트와 관련하여 대한민국 특허청에 선출원 공개(대한민국 특허공개 제2018-0027222)된 "친환경 가소제를 이용하여 제조된 인테리어시트"가 창안된바 있다.On the other hand, as a way to solve some of the problems described above, "interior sheets manufactured using eco-friendly plasticizers", which were published in an earlier application to the Korean Intellectual Property Office (Korean Patent Publication No. 2018-0027222) in relation to interior sheets among conventional sheets, were created. there is a bar
이와 같은, 선등록 공개기술로서의 "친환경 가소제를 이용하여 제조된 인테리어시트"는 자연에서 유래된 구연산과, 2종 이상의 알코올과의 반응에 의해 합성된 친환경 가소제를 이용하여 형성된 PVC 발포층을 포함하는 인테리어시트를 특징으로 한다.As such, "interior sheet manufactured using an eco-friendly plasticizer" as a pre-registered open technology includes a PVC foam layer formed using an eco-friendly plasticizer synthesized by the reaction of citric acid derived from nature and two or more alcohols.

이에, 단순한 가소제 성분의 대체뿐만 아니라, 시트를 제조하는 주요 소재 또한 변화시켜, 화재 발생 또는 소각 작업시 유해 가스 및 유해 물질의 배출을 원천 차단할 수 있도록 한 새로운 개념의 친환경 시트의 개발을 절실히 요구하는 실정이다.Accordingly, there is an urgent need for the development of a new concept eco-friendly sheet that not only replaces the simple plasticizer component, but also changes the main material for manufacturing the sheet, thereby blocking the emission of harmful gases and harmful substances at the source during fire or incineration. the current situation.
한편, 최근에는 상기 공개된 "친환경 가소제를 이용하여 제조된 인테리어시트"의 문제점을 해결하기 위한 방안으로, 본원 발명자에 의해 선출원 등록된 "친환경 장식용 인테리어시트 제조방법 및 그 인테리어시트"가 창안된 바 있다.On the other hand, recently, as a way to solve the problem of the disclosed "interior sheet manufactured using an eco-friendly plasticizer", "a method for manufacturing an eco-friendly decorative interior sheet and its interior sheet" registered in the earlier application by the inventor of the present application was created. have.

Although it exhibits a very excellent function in the context of daily use, additional functions that can help the user's body or the surrounding environment other than the simple characteristics of an eco-friendly technology product cannot be expected at all.
또한, 필름지의 원재료를 폴리프로필렌으로 한정하였으므로, 활용성 저하의 폐단이 상존한다.In addition, since the raw material of the film paper is limited to polypropylene, the disadvantage of lowering the usability is always present.
따라서, 단순히 친환경이라는 특성뿐만 아니라, 일상적인 사용관계에 있어 다양한 부가기능과 효과를 기대할 수 있으며, 다른 원재료를 이용하여 제조되어 패션, 가죽 및 생활 잡화의 생산에 사용되는 시트의 개발이 절실히 요구되는 실정이다.Therefore, not only the characteristics of being eco-friendly, but also various additional functions and effects can be expected in the relationship of daily use, and the development of sheets manufactured using other raw materials to be used in the production of fashion, leather and household goods is urgently required. the current situation.
