폴리프로필렌을 이용한 Non-PVC 타입 친환경 타일{Non-PVC eco-friendly tiles using polypropylene}Non-PVC eco-friendly tiles using polypropylene

본 발명은 PP(Polypropylene)를 이용한 Non-PVC(Poly Vinyl Chloride) 타입 친환경 타일에 관한 것으로, 보다 상세하게는 친환경 소재인 PP를 이용하여 바닥재로 사용되는 타일을 구현함으로써 PVC 소재 및 프탈레이트계 가소제를 사용한 타일과 달리 유해물질이 배출되지 않아 친환경적일 뿐만 아니라 캘린더링이 우수하여 성형하기 좋고, 기존 PVC 타일과 동등이상의 경제성 및 내스크래치성을 가지면서 영하 10℃∼50℃ 범위내에서 수축이나 들뜸이 발생하지 않는 강한 내구성을 갖도록 개선된 폴리프로필렌을 이용한 Non-PVC 타입 친환경 타일에 관한 것이다.The present invention relates to a Non-PVC (Poly Vinyl Chloride) type eco-friendly tile using PP (Polypropylene), and more particularly, by implementing a tile used as a flooring material using PP, an eco-friendly material, a PVC material and a phthalate-based plasticizer Unlike used tiles, it is eco-friendly because it does not emit harmful substances, and it is good for molding due to excellent calendering. It has economical efficiency and scratch resistance equivalent to or better than existing PVC tiles, and shrinkage or lifting within the range of -10°C to 50°C below zero. It relates to a Non-PVC type eco-friendly tile using polypropylene improved to have strong durability that does not occur.

통상, 바닥재로 사용되는 타일은 보통 폴리염화비닐(PVC, Poly Vinyl Chloride) 또는 염화비닐에 다른 소재를 혼합하거나 라미네이션(Lamination)하여 제조되는 것이 일반적이다.In general, tiles used as flooring materials are generally manufactured by mixing or laminating other materials with polyvinyl chloride (PVC, Poly Vinyl Chloride) or vinyl chloride.

최근에는 LVT(Luxury Vinyl Tile) 등이 개시되고 있다.Recently, LVT (Luxury Vinyl Tile) and the like have been disclosed.

LVT는 PVC 중에서도 가장 비싼 비닐 재료로 강하게 만든 것이기 때문에 내구성이 매우 뛰어난 장점이 있다. 또한, 접착제를 이용하여 시공하기 때문에 논슬립성도 우수하다.Since LVT is made of the most expensive vinyl material among PVC, it has the advantage of excellent durability. In addition, since it is constructed using an adhesive, it has excellent non-slip properties.

그런데, LVT도 PVC를 기초로 만들어진 타일이기 때문에 이러한 타일의 경우 필수적으로 프탈레이트(Phthalate)계 가소제가 혼합되어야 한다.However, since LVT is also a tile made based on PVC, in the case of such a tile, a phthalate-based plasticizer must be necessarily mixed.

하지만, 프탈레이트계 가소제는 환경호르몬을 유발하며, 또한 소각시에도 환경호르몬인 다이옥신(Dioxin)을 발생시키기 때문에 이러한 환경문제로 인해 선진국을 포함한 대부분의 국가에서 사용이 규제되고 있으며, 기피현상이 심화되고 있다.However, phthalate-based plasticizers cause environmental hormones and also generate environmental hormones, dioxin, during incineration. Due to these environmental problems, their use is regulated in most countries, including developed countries, and the avoidance phenomenon is intensifying. there is.

이러한 문제를 해결하기 위해 환경친화적 소재인 열가소성 폴리우레탄(TPU)의 사용을 고려할 수 있으나, 열가소성 폴리우레탄은 점착성이 강하여 캘린더링할 수 없어 연속가공이 어렵기 때문에 생산성이 급격히 떨어지는 단점이 있다.In order to solve this problem, it is possible to consider the use of thermoplastic polyurethane (TPU), which is an environmentally friendly material, but since thermoplastic polyurethane cannot be calendered due to its strong adhesiveness, continuous processing is difficult, and thus productivity is rapidly reduced.

뿐만 아니라, 단순히 가공성의 문제가 아니라, 대체시 친환경적이어야 하며, 경제성도 포함해야 하고, 내스크래치성과 사용온도 범위내에서의 수축이나 들뜸에 의한 탈락이나 층분리 등이 생기지 않는 강한 내구성을 갖추어야 한다.In addition, it is not simply a matter of processability, but it should be environmentally friendly and economical when replacing, and it should have scratch resistance and strong durability that does not cause drop-off or layer separation due to shrinkage or lifting within the operating temperature range.

하지만, 현실적으로 이를 모두 만족시키는 대안이 없는 실정이다.However, in reality, there is no alternative that satisfies all of them.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

본 발명 설명에 앞서, 이하의 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있으며, 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니된다.Prior to the description of the present invention, the following specific structural or functional descriptions are only exemplified for the purpose of describing embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms, It should not be construed as limited to the embodiments described herein.

[제1실시예][First embodiment]

도 1에 예시된 바와 같이, 본 발명 제1실시예에 따른 폴리프로필렌을 이용한 Non-PVC 타입 친환경 타일은 주로 2.0mm 두께에 적용되는 구조이다.As illustrated in FIG. 1 , the Non-PVC type eco-friendly tile using polypropylene according to the first embodiment of the present invention has a structure mainly applied to a thickness of 2.0 mm.

이러한 타일은 베이스층(100)을 기준으로 그 하면에 합판되는 하부필름층(110)과, 상기 베이스층(100)의 상면에 인쇄형성되는 인쇄층(120)과, 상기 인쇄층(120)을 보호하도록 상기 베이스층(100)의 상면에 합판되는 상부필름층(130)으로 이루어진다.The tile includes a lower film layer 110 plywood on its lower surface based on the base layer 100 , a print layer 120 printed on the upper surface of the base layer 100 , and the print layer 120 . It consists of an upper film layer 130 that is laminated on the upper surface of the base layer 100 to protect it.

이때, 상기 타일은 모든 층들은 기존과 달리 PVC를 전혀 포함하고 있지 않다는데 특징이 있다.At this time, the tile is characterized in that all layers do not contain PVC at all, unlike the existing ones.

그런데, PVC를 사용하지 않을 경우 수축, 팽창에 대한 물성 저하가 우려될 수 있다.However, if PVC is not used, there may be concerns about deterioration of physical properties against shrinkage and expansion.

이에, 본 발명에서는 메인층인 베이스층(100)을 구성할 때 충전제를 종래와 달리 과량으로 첨가하는 특징이 있다.Accordingly, in the present invention, when configuring the base layer 100, which is the main layer, the filler is added in an excessive amount unlike the prior art.

예컨대, 종래 PVC를 사용할 때는 필러(filler)를 20중량% 이상 첨가하게 되면 가공성이 떨어지기 때문에 이를 배제해야 하지만, 본 발명에서는 폴리프로필렌 수지를 사용하기 때문에 원가도 절감할 수 있도록 고필러 방식으로 유도하되, 오히려 플렉시블성과 성형성을 높이도록 배합 구성된다.For example, when using conventional PVC, if 20% by weight or more of filler is added, it should be excluded because processability is deteriorated, but in the present invention, polypropylene resin is used, so it is induced in a high filler method to reduce cost. However, it is rather formulated to increase flexibility and moldability.

뿐만 아니라, 고필러를 통해 본 발명에서는 첨가성분들간의 바인딩성을 개선하여 영하 10℃ 내지 50℃ 사이에서의 수축 및 팽창에 대한 저항성, 내스크래치성을 높여 기존 PVC를 사용할 때와 동등 이상의 물성을 확보하도록 한다.In addition, in the present invention through high filler, the binding properties between the additives are improved, and the resistance to shrinkage and expansion between -10°C to 50°C, and scratch resistance are increased to have properties equivalent to or higher than when using conventional PVC. to secure

이를 위해, 상기 베이스층(100)은 폴리프로필렌 수지 18-23중량%와, TPE(Thermo Plastic Elastomer) 1-2중량%와, 선형저밀도 폴리에틸렌(LLDPE) 7.5-12.5중량%와, 아크릴 변성 폴리테트라플루오로에틸렌(PTFE) 0.3-0.6중량%와, 고분자 아크릴 윤활유 0.3-0.6중량%와, 분산제 0.3-0.6중량% 및 나머지 탄산칼슘으로 조성된 조성물을 성형한 시트로 이루어진다.To this end, the base layer 100 includes 18-23% by weight of polypropylene resin, 1-2% by weight of TPE (Thermo Plastic Elastomer), 7.5-12.5% by weight of linear low-density polyethylene (LLDPE), and acrylic-modified polytetra It consists of a sheet molded with a composition composed of 0.3-0.6% by weight of fluoroethylene (PTFE), 0.3-0.6% by weight of a polymer acrylic lubricant, 0.3-0.6% by weight of a dispersant, and the remaining calcium carbonate.

이때, 상기 폴리프로필렌 수지는 친환경소재로서 PVC를 대체하면서 가공시 우수한 열 안정성을 제공한다. 다만, 23중량%를 초과하면 연신성과 가공성이 너무 커지고, 18중량% 미만으로 첨가되면 연신성과 가공성이 너무 떨어지기 때문에 상기 범위로 한정해야 한다.In this case, the polypropylene resin provides excellent thermal stability during processing while replacing PVC as an eco-friendly material. However, if it exceeds 23% by weight, the stretchability and workability are too large, and if it is added at less than 18% by weight, the stretchability and workability are too poor, so it should be limited to the above range.

또한, 상기 TPE는 가공성을 보강하고 강도와 유동성 특성을 강화시키면서 표면 촉감 상승, 필러의 사용을 늘려도 물성이 저하되지 않도록 하기 위해 첨가된다.In addition, the TPE is added to enhance workability and enhance strength and fluidity characteristics, while increasing the surface feel and preventing deterioration of physical properties even if the use of filler is increased.

그리고, 상기 LLDPE는 인장강도와 신장율, 인열강도, 투명도 및 열봉합성이 우수하여 가공시 생기는 불안정한 균열에 대한 저항성을 높이기 위해 첨가된다.In addition, the LLDPE is added to increase resistance to unstable cracks generated during processing because it has excellent tensile strength, elongation, tear strength, transparency and heat-sealability.

다만, 12.5중량%를 초과하면 연신력과 표면균일도가 과다하게 증가되어 오히려 성능을 떨어뜨리고, 7.5중량% 미만으로 첨가되면 강도와 연신력 및 표면균일도가 급격히 떨어지기 때문에 상기 범위로 한정해야 한다.However, if it exceeds 12.5% by weight, the stretching force and surface uniformity are excessively increased, and the performance is rather deteriorated, and when it is added to less than 7.5% by weight, the strength, the stretching force and the surface uniformity are sharply decreased. Therefore, it should be limited to the above range.

뿐만 아니라, 상기 아크릴 변성 폴리테트라플루오로에틸렌(PTFE)은 열가소성 수지에 잘 분산된 미세섬유를 쉽게 형성하여 가열하면서 혼련될 때 네트워크 구조를 형성하여 수지의 장력을 높이고, 이를 통해 가공성을 향상시키는데 기여한다.In addition, the acrylic-modified polytetrafluoroethylene (PTFE) easily forms fine fibers well dispersed in the thermoplastic resin and forms a network structure when kneaded while heating to increase the tension of the resin, thereby contributing to improving processability do.

아울러, 상기 고분자 아크릴 윤활유는 용융온도가 낮은 원재료가 가공중 고착되는 것을 방지하는 일종의 개질제이다.In addition, the polymer acrylic lubricating oil is a kind of modifier that prevents the raw material having a low melting temperature from sticking during processing.

그리고, 상기 분산제는 당해 분야에서 흔히 사용하는 첨가제로 특별히 한정하지는 않는다.In addition, the dispersing agent is not particularly limited to additives commonly used in the art.

마지막으로, 상기 탄산칼슘은 필러로서, 충전성은 물론 하드니스를 강화시키기 위해 첨가된다.Finally, the calcium carbonate is added as a filler to enhance the hardness as well as the filling properties.

특이한 점은 기존 PVC의 경우에는 탄산칼슘을 가급적 적게 첨가해야 하지만, 본 발명에서는 특수성분들의 조합을 통해 고필러, 즉 탄산칼슘 첨가량을 높인 것이 특징이다.What is peculiar is that, in the case of conventional PVC, calcium carbonate should be added as little as possible, but in the present invention, the high filler, that is, the amount of calcium carbonate added is increased through a combination of special ingredients.

이는 브리틀(Brittle)을 방지하면서 일정한 플렉시블성을 갖추고 수측, 팽창에 대한 변형 저항성을 높이기 위한 것이다.This is to prevent brittle, have constant flexibility, and increase deformation resistance against water side and expansion.

한편, 상기 하부필름층(110)과 상부필름층(130)은 100% 폴리프로필렌 수지, 즉 단독으로 만든 필름을 사용한다. 이는 투명성이 우수하고 내구성이 좋기 때문이다.On the other hand, the lower film layer 110 and the upper film layer 130 uses 100% polypropylene resin, that is, a film made by itself. This is because transparency is excellent and durability is good.

[제2실시예][Second embodiment]

도 2에 예시된 바와 같이, 본 발명 제2실시예에 따른 폴리프로필렌을 이용한 Non-PVC 타입 친환경 타일은 주로 3.0mm 두께에 적용되는 구조이다.As illustrated in FIG. 2 , the Non-PVC type eco-friendly tile using polypropylene according to the second embodiment of the present invention has a structure mainly applied to a thickness of 3.0 mm.

이러한 타일은 베이스층(100)을 기준으로 그 하면에 합판되는 밸런스층(200)과, 상기 베이스층(100)의 상면에 합판되는 상지층(210)과, 상기 상지층(210)에 인쇄형성되는 인쇄층(120)과, 상기 인쇄층(120)을 보호하도록 상기 상지층(210)의 상면에 합판되는 상부필름층(130)으로 이루어진다.The tile is formed by printing on the base layer 100 , the balance layer 200 being laminated on its lower surface, the upper layer 210 being plywood on the upper surface of the base layer 100 , and the upper layer 210 . It consists of a printed layer 120 to be used, and an upper film layer 130 laminated on the upper surface of the upper layer 210 to protect the printed layer 120 .

이때, 상기 베이스층(100)과 상부인쇄층(130)은 앞서 설명한 제1실시예에서와 동일한 조성으로 이루어진다.In this case, the base layer 100 and the upper printed layer 130 have the same composition as in the first embodiment described above.

다만, 상기 밸러스층(200)은 타일의 컬링(Curling)을 잡아 주면서 두께를 조절하기 위해 구비되는 층이다.However, the balance layer 200 is a layer provided to control the thickness while holding the curling (curling) of the tile.

또한, 상기 상지층(210)은 투명성을 갖는 시트로서 하드니스(Hardness)를 증대시켜 내구성을 향상시키면서 두께를 조절하기 위해 구비되는 층이다.In addition, the upper layer 210 is a sheet having transparency, and is a layer provided to control thickness while improving durability by increasing hardness.

즉, 밸런스층(200)과 상지층(210)는 동일 조성으로 이루어진 것이지만, 배치되는 위치에 따라 기능이 조금 차이가 있을 뿐이다.That is, the balance layer 200 and the upper layer 210 are made of the same composition, but only have slightly different functions depending on the arrangement position.

이러한 밸런스층(200)과 상지층(210)도 베이스층(100)과 기본적인 성분을 동일 유사하지만, 조성비율이 달라짐으로써 물성이 조금 바뀌도록 구성된다.The balance layer 200 and the upper layer 210 also have the same basic components as the base layer 100, but are configured such that the physical properties are slightly changed due to the different composition ratios.

예컨대, 밸런스층(200)과 상지층(210)은 폴리프로필렌 수지 20-25중량%와, TPE(Thermo Plastic Elastomer) 2-5중량%와, 선형저밀도 폴리에틸렌(LLDPE) 7.5-12.5중량%와, 아크릴 변성 폴리테트라플루오로에틸렌(PTFE)과 고분자 아크릴 윤활유가 1:1의 중량비로 혼합된 혼합물 0.3-0.8중량%와, 분산제 0.3-0.6중량% 및 나머지 탄산칼슘으로 조성된 조성물을 성형한 시트로 이루어진다.For example, the balance layer 200 and the upper layer 210 are 20-25% by weight of polypropylene resin, 2-5% by weight of TPE (Thermo Plastic Elastomer), and 7.5-12.5% by weight of linear low-density polyethylene (LLDPE), A sheet formed by molding a composition composed of 0.3-0.8% by weight of a mixture of acrylic-modified polytetrafluoroethylene (PTFE) and high molecular weight acrylic lubricant in a 1:1 weight ratio, 0.3-0.6% by weight of a dispersant, and the rest of calcium carbonate. is done

이 경우에는 아크릴 변성 폴리테트라플루오로에틸렌과 고분자 아크릴 윤활유가 1:1의 중량비로 혼합된 혼합물로 첨가한다는 점에서 차이가 나는데, 이는 두 성분을 먼저 혼합하여 점탄성을 확보한 상태에서 첨가되도록 하여 가공조제와의 충격보강성을 높이고 분산성을 더욱 개선하도록 한 것이다.In this case, the difference is that acrylic-modified polytetrafluoroethylene and polymer acrylic lubricant are added as a mixture in a weight ratio of 1:1, which is processed by mixing the two components first to ensure viscoelasticity. It is intended to enhance impact reinforcement with the formulation and further improve dispersibility.

이를 통해, 고필러를 사용하더라도 강한 바인딩성 구축으로 물성을 개선할 수 있도록 한 것이다.Through this, even if high filler is used, physical properties can be improved by building strong binding properties.

본 발명에 따른 제1,2실시예에 대한 물성을 테스트하여 경쟁사(UPOFLOOR, 미국)의 3가지 제품과 실제로 비교판독하였고, 그 결과를 표 1에 나타내었다.The physical properties of Examples 1 and 2 according to the present invention were tested and actually compared and read with three products of a competitor (UPOFLOOR, USA), and the results are shown in Table 1.

위 표 1의 결과에서와 같이, 본 발명에 따른 제1,2실시예는 필터를 다량함유했음에도 불구하고, 기존 PVC 타일이 갖는 물성과 동등 이상의 더 나은 특성(영하 10℃ 내지 영상 50℃ 범위 내에서의 수축, 팽창 특성)이 있음을 확인할 수 있었다.As shown in the results of Table 1 above, the first and second examples according to the present invention, despite containing a large amount of filters, have better properties (within the range of -10 ℃ to 50 ℃ below zero to the physical properties of the existing PVC tiles) shrinkage and expansion characteristics) were confirmed.

또한, 박리성과 면 상태를 확인하였는 바, 비교예의 (제품1,2,3)은 주름(Brittle) 혹은 에어포켓이 확인되었으나 발명예의 경우에는 매우 양호한 표면을 확인할 수 있었고; 박리여부의 경우에는 비교예 및 발명예 모두 박리되지 않았다.In addition, when the peelability and the surface state were checked, brittle or air pockets were confirmed in the comparative examples (Products 1, 2, and 3), but in the case of the invention example, a very good surface was confirmed; In the case of peeling, neither Comparative Example nor Inventive Example did not peel.

뿐만 아니라, 기존 PVC 대비 가공온도 10℃ 상승시 유사 가공성을 비교 분석한 결과, 아래 표 2에서와 같이 본 발명에 따른 발명예(PP 타일)가 훨씬 우수한 가공성을 가짐을 확인할 수 있었다.In addition, as a result of comparative analysis of similar processability when the processing temperature is increased by 10° C. compared to conventional PVC, it was confirmed that the inventive example (PP tile) according to the present invention has much better processability as shown in Table 2 below.

이를 통해, 본 발명에 따른 타일을 이용하여 기존 PVC 타일을 충분히 대체할 수 있을 것으로 기대된다.Through this, it is expected that the existing PVC tile can be sufficiently replaced by using the tile according to the present invention.
