Description

무광 장판{Matte flooring}Matte flooring

본 발명은 무광 장판에 관한 것으로, 보다 상세하게는 PET(polyethylene terephthalate)를 기재로 한 장판의 유광 특성을 무광 특성으로 변화시켜 소비자의 다양한 구매 욕구를 증진시킬 수 있도록 개선된 무광 장판에 관한 것이다.The present invention relates to a matte floorboard, and more particularly, to a matte floorboard improved to improve various purchase desires of consumers by changing the gloss characteristics of the floorboard based on PET (polyethylene terephthalate) into matte characteristics.

일반적으로 장판이라 함은 시멘트 몰탈로 된 건물의 실내 바닥면에 깔아 시공함으로써 시멘트 몰탈로부터 난방 및 방습의 역할을 수행하는 것임은 익히 알려진 바와 같다.In general, it is well known that a floorboard is a cement mortar that is installed on the indoor floor surface of a building, thereby performing the role of heating and moisture-proofing from the cement mortar.

이러한 장판은 일찍이 전통적으로 종이의 상면에 기름을 먹인 종이 장판지가 통상적으로 사용되어 왔으나, 근래에 들어서는 방습이나 쿠션감, 시공의 편리함을 내세운 합성수지재 장판이 널리 보급되어 사용되고 있는 실정이다.As for such a floorboard, paper floorboards, which were traditionally fed with oil on the upper surface of paper, have been commonly used, but recently, synthetic resin floorboards, which emphasize moisture-proof, cushioning, and convenience in construction, have been widely used and used.

대표적인 합성수지재 장판으로 PVC 장판을 들 수 있다.PVC flooring is a representative synthetic resin flooring.

PVC 장판은 저렴하고 습기나 오염에 강할 뿐만 아니라, 열전도율이 높아 난방에 유리하다는 장점이 있다.PVC floor coverings are inexpensive and resistant to moisture and contamination, and have the advantage of being advantageous for heating due to their high thermal conductivity.

하지만, 인장강도가 낮아 딱딱하고 쿠션감이 떨어질 뿐만 아니라, 외부충격에 약하다는 단점이 있다.However, due to its low tensile strength, it is not only hard and cushioned, but also has a disadvantage in that it is weak against external impact.

이에, PET 장판이 개시되고 있다. PET 장판은 유광으로서 가격이 저렴하고 연질이어서 쿠션감이 좋고 외부 충격을 완충하는 능력이 우수함에 반해, 열에 의해 수축팽창되는 단점이 있다.Thus, PET flooring has been disclosed. PET floorboards are glossy, inexpensive, and soft, so they have a good cushioning feeling and are excellent in buffering external shocks, but have the disadvantage of shrinking and expanding by heat.

하여, 최근에는 PET의 상하면을 프라이머(Primer) 처리하여 PET 장판의 단점을 보완하려는 시도들이 이루어졌다.Thus, in recent years, attempts have been made to supplement the shortcomings of PET flooring by treating the upper and lower surfaces of PET with a primer.

그런데, 소비자의 기호도 변화로 무광 장판을 선호함에 따라 프라이머처리된 PET 장판을 무광처리하려고 하니 무광처리가 매우 어렵다는 한계에 봉착하게 되었다.However, as consumers prefer matte floorboards due to changes in consumer preferences, they are faced with the limitation that matte treatment is very difficult as they try to matte the primer-treated PET floorboards.

즉, 장판의 무광처리는 통상 열롤러를 이용하여 장판 표면을 약간 녹여 미세 거칠기를 형성함으로써 광택을 없애는 방식으로 이루어지는데, 이 열롤러는 최대 150℃ 미만으로 가열된 상태로 사용됨에 반해, PET는 240℃를 넘어서야 녹기 때문에 통상의 열롤러를 이용하여 무광처리하기 어렵다는 한계에 봉착해 있다.In other words, the matting treatment of the floorboard is usually performed in a manner that removes the gloss by slightly melting the surface of the floorboard using a heat roller to form a fine roughness. This heat roller is used in a state heated to less than 150℃, whereas PET Since it melts only when it exceeds 240°C, it is difficult to matte it using a conventional heat roller.

본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점들을 감안하여 이를 해결하고자 창출된 것으로, PET(polyethylene terephthalate)를 기재로 한 장판의 유광 특성을 무광 특성으로 변화시켜 소비자의 다양한 구매 욕구를 증진시킬 수 있도록 개선된 무광 장판을 제공함에 그 주된 목적이 있다.The present invention was created to solve the problems in the prior art as described above, and by changing the gloss characteristics of a floor plate based on PET (polyethylene terephthalate) into a matte characteristic, it is possible to improve various purchase desires of consumers. Its main purpose is to provide an improved matte flooring.

본 발명은 상기한 목적을 달성하기 위한 수단으로, 기재(100)와, 상기 기재(100)의 하면에 인쇄형성되는 인쇄층(200)과, 상기 기재(100)의 상면에 형성되는 상지층(300)으로 이루어진 무광 장판에 있어서; 상기 상지층(300)은 PVC 필름이 합지되어 형성되며, 열롤러에 의해 표면처리되어 거칠기를 갖도록 무광처리된 것을 특징으로 하는 무광 장판을 제공한다.The present invention is a means for achieving the above object, a substrate 100, a print layer 200 formed to be printed on the lower surface of the substrate 100, and an upper layer formed on the upper surface of the substrate 100 ( In the matte floor plate consisting of 300); The upper layer 300 is formed by laminating a PVC film, and is surface-treated by a heat roller to provide a matte floor plate, characterized in that it is matte-treated to have roughness.

본 발명에 따르면, PET(polyethylene terephthalate)를 기재로 한 장판의 유광 특성을 무광 특성으로 변화시켜 소비자의 다양한 구매 욕구를 증진시킬 수 있도록 개선된 효과를 얻을 수 있다.According to the present invention, an improved effect can be obtained so as to improve various purchase desires of consumers by changing the gloss property of a floor plate based on PET (polyethylene terephthalate) into a matte property.

도 1은 본 발명에 따른 무광 장판의 층상구조를 보인 예시적인 단면도이다.1 is an exemplary cross-sectional view showing a layered structure of a matte floor plate according to the present invention.

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

본 발명에 따른 무광 장판은 PET 기재의 상면에 PVC 상지층을 형성하여 무광처리 가능하게 구성한 것이 특징이다.The matte floorboard according to the present invention is characterized by forming a PVC upper layer on the upper surface of a PET substrate to enable matte treatment.

이때, PVC 상지층은 0.1mm 이내의 두께를 갖는다.At this time, the PVC upper layer has a thickness within 0.1mm.

이렇게 PVC 상지층을 형성하는 이유는 PVC의 경우 녹는점이 140℃이기 때문에 열롤러를 통한 무광처리가 가능하기 때문이다.The reason for the formation of the PVC upper layer is that in the case of PVC, the melting point is 140°C, and thus matte treatment is possible through a heat roller.

더구나, PET 장판의 장점과 PVC 장판의 장점을 함께 갖추도록 일종의 하이브리드 개념이 구현되게 하여 PET 장판과 PVC 장판의 단점이 모두 제거되게 함으로써 장판 구매자의 기호도를 높이고, 품질 개선에 기여할 수 있도록 한다.In addition, a kind of hybrid concept is implemented to have the merits of PET and PVC flooring, so that both the disadvantages of PET and PVC flooring are eliminated, thereby enhancing the preference of the flooring buyer and contributing to quality improvement.

다만, 양자를 단순히 합친다고 해서 혼합된 장판이 구현되기는 어렵기 때문에 그것을 가능하게 구현한 것이 사실상 본 발명의 특징이라 할 수 있다.However, since it is difficult to implement a mixed floor plate simply by combining the two, it can be said to be a feature of the present invention that it is possible to implement it.

보다 구체적으로, 도 1의 예시와 같이 본 발명에 따른 무광 장판은 기재(100)와, 상기 기재(100)의 하면에 인쇄형성되는 인쇄층(200)과, 상기 기재(100)의 상면에 형성되는 상지층(300)으로 이루어진다.More specifically, as illustrated in FIG. 1, the matte floor plate according to the present invention includes a substrate 100, a printing layer 200 printed on the lower surface of the substrate 100, and an upper surface of the substrate 100. It consists of an upper layer (300).

이때, 기재(100)는 PET 시트(110)의 상하면이 코로나처리된 상태에서 상부프라이머(120)와 하부프라이머(130)가 도포 형성된 구조를 갖는다.At this time, the substrate 100 has a structure in which the upper and lower primers 120 and the lower primers 130 are coated in a state in which the upper and lower surfaces of the PET sheet 110 are corona-treated.

여기에서, 코로나처리란 PET 시트(110)를 코로나 방전장에 통과시켜 그 상면과 하면을 개질함으로써 습윤장력 향상, 인쇄성, 도포성, 부착성을 높이기 위한 표면처리기술이다.Here, the corona treatment is a surface treatment technology for improving wet tension, printability, applicability, and adhesion by passing the PET sheet 110 through a corona discharge field and modifying the upper and lower surfaces thereof.

즉, 일반적으로 플라스틱 표면은 낮은 에너지를 가지며 화학적으로 불활성 상태여서 이러한 특성 때문에 표면은 코팅, 인쇄 등으로 매우 어렵기 때문에 코로나 처리를 통해 극성 작용기를 재료 표면에 적용하여 친수성을 개선함으로써 인쇄성, 도포성, 부착성 등의 기능을 향상시키도록 표면처리하는 것을 말한다.That is, in general, plastic surfaces have low energy and are chemically inert, and because of these properties, the surface is very difficult to coat, print, etc., so by applying a polar functional group to the material surface through corona treatment to improve the hydrophilicity, printability and application It refers to surface treatment to improve functions such as property and adhesion.

아울러, 상기 상부프라이머(120)와 하부프라이머(130)는 아크릴수지가 도포되어 형성되는 것으로, 아크릴수지는 빛투과성이 우수하고, 특히 열에 대한 변형이 적어 PET 시트(110)의 열변형을 방지하는 특성을 갖는다.In addition, the upper primer 120 and the lower primer 130 are formed by applying an acrylic resin, and the acrylic resin has excellent light transmittance, and in particular, has less deformation to heat to prevent thermal deformation of the PET sheet 110. Has characteristics.

또한, 하부프라이머(130)의 경우, 인쇄층(200)이 양호하게 형성될 수 있도록 하부프라이머(130)를 구성하는 아크릴수지 100중량부에 대해, 규산칼슘 5중량부, 에폭시수지 8.5중량부 및 불소알킬실란 4중량부가 더 첨가된다.In addition, in the case of the lower primer 130, based on 100 parts by weight of the acrylic resin constituting the lower primer 130 so that the printing layer 200 can be formed satisfactorily, 5 parts by weight of calcium silicate, 8.5 parts by weight of the epoxy resin, and 4 parts by weight of fluorine alkylsilane is further added.

이때, 상기 규산칼슘은 인쇄층(200)의 광택성을 확보하기 위해 첨가된다.At this time, the calcium silicate is added to secure the glossiness of the printing layer 200.

그리고, 상기 에폭시수지는 투명성이 좋아 인쇄층(200)의 형상이 잘 투영되면서 볼륨감 및 완충감을 확보하도록 하기 위해 첨가된다.In addition, the epoxy resin has good transparency and is added to ensure a sense of volume and a sense of buffer while the shape of the printing layer 200 is well projected.

아울러, 상기 불소알킬실란은 미세구조화에 의해 평활성을 유지하여 인쇄층(200)이 고르고 균일하에 형성될 수 있도록 하기 위해 첨가된다.In addition, the fluoroalkylsilane is added to maintain smoothness by microstructuring so that the printing layer 200 can be formed evenly and uniformly.

또한, 상기 인쇄층(200)은 원목무늬 등 다양한 바닥재 느낌을 갖도록 형상화되게 인쇄될 수 있다.In addition, the printing layer 200 may be printed to have a shape to have various flooring feelings such as a solid wood pattern.

한편, 상기 상지층(300)은 PVC 필름(330)을 포함하는데, PVC 필름(330)은 PET 시트(100)에 잘 붙지 않는다.On the other hand, the upper layer 300 includes a PVC film 330, the PVC film 330 does not adhere well to the PET sheet (100).

따라서, 본 발명에서는 이들 합지성을 좋게 하기 위해 상부프라이머(120)와의 교합성을 증진시킬 수 있도록 상지층(300)을 다음과 같이 구성한다.Therefore, in the present invention, the upper layer 300 is configured as follows so as to improve the mating with the upper primer 120 in order to improve the lamination property.

상기 상지층(300)은 상기 상부프라이머(120)와 합지되는 제1프라이머(310), 상기 제1프라이머(310)의 상면에 형성되는 제2프라이머(320) 및 상기 제2프라이머(320)의 상면에 합지되는 PVC 필름(330)으로 이루어진다.The upper layer 300 includes a first primer 310 laminated with the upper primer 120, a second primer 320 formed on the upper surface of the first primer 310, and the second primer 320. It consists of a PVC film 330 laminated on the upper surface.

이때, 상기 제1프라이머(310)는 상기 기재(100)를 구성하는 상부프라이머(120)와의 교합을 위해 PVC 수지와 아크릴수지가 1:1의 중량비로 혼합된 프라이머액을 스프레이하여 형성된다.At this time, the first primer 310 is formed by spraying a primer solution in which a PVC resin and an acrylic resin are mixed in a weight ratio of 1:1 for occlusion with the upper primer 120 constituting the substrate 100.

이것은 제1프라이머(310)에 아크릴수지가 함유되게 하여 아크릴수지로 형성된 상부프라이머(120)와 완전한 교합이 이루어지게 하여 견고한 부착력으로 합지되게 하기 위함이다.This is to allow the first primer 310 to contain an acrylic resin so that a complete occlusion with the upper primer 120 formed of the acrylic resin is achieved so that it is bonded with a strong adhesive force.

다만, 사실은 PVC 필름(330)의 하면에 제2프라이머(320)가 도포 형성되고, 이 제2프라이머(320) 상에 제1프라이머(310)가 도포 형성되는 것이지만, 설명의 편의를 위해 위에서는 반대로 설명하였다.However, in fact, the second primer 320 is applied and formed on the lower surface of the PVC film 330, and the first primer 310 is applied and formed on the second primer 320, but for convenience of explanation, Explained the opposite.

덧붙여, 상기 제1프라이머(310)는 PVC 수지와 아크릴수지가 1:1의 중량비로 혼합된 프라이머액 100중량부에 대해, 옴모크롬(ommochrome) 10중량부, 옥타메틸사이클로테트라실록산(octamethylcyclotetrasiloxane) 5중량부를 더 첨가하여 구성할 수도 있다.In addition, the first primer 310 includes 10 parts by weight of ommochrome, 5 parts by weight of octamethylcyclotetrasiloxane, based on 100 parts by weight of a primer solution in which a PVC resin and an acrylic resin are mixed in a weight ratio of 1:1. It may be configured by adding more parts by weight.

이 경우, 옴모크롬은 천연방부 및 천연 항바이러스 특성을 갖는 것으로 필름 표면에서 오랫동안 잔류되는 특성이 있어 항균지속성을 유지하기 위해 첨가되고; 옥타메틸사이클로테트라실록산은 방수성 유기물로서 발수성을 증대시키면서 접촉각을 크게 하여 미끄럼성을 높임으로써 내지문성을 강화시키기 위해 첨가된다.In this case, ommochrome has natural antiseptic and natural antiviral properties and is added to maintain antibacterial persistence because it has a property of remaining on the film surface for a long time; Octamethylcyclotetrasiloxane is a water-repellent organic substance and is added to enhance the anti-fingerprint property by increasing the contact angle and increasing the slip property while increasing the water repellency.

또한, 상기 제2프라이머(320)는 PVC 필름(330)을 제1프라이머(310)에 부착시켜 합지해야 하므로 PVC 수지로 형성된다.In addition, the second primer 320 is formed of a PVC resin because it must be laminated by attaching the PVC film 330 to the first primer 310.

즉, 제1프라이머(320)에도 PVC가 있고, PVC 필름(330)도 PVC로 된 것이므로 제2프라이머(320)는 이들 사이에서 이들을 교합시키게 되며, 교합의 원활성과, 견고한 합지력을 제공하게 된다.That is, since the first primer 320 also has PVC, and the PVC film 330 is also made of PVC, the second primer 320 occludes them between them, providing smooth occlusion and a solid bonding force. .

특히, 본 발명에서는 상기 제2프라이머(320)에 이를 구성하는 PVC 수지 100중량부에 대해, 비닐옥시모실란 10중량부, 제올라이트 미분 2.5중량부, 벤조구아나민 5중량부를 더 첨가할 수 있다.In particular, in the present invention, 10 parts by weight of vinyloxymosilane, 2.5 parts by weight of zeolite fine powder, and 5 parts by weight of benzoguanamine may be further added to the second primer 320 with respect to 100 parts by weight of the PVC resin constituting it.

이때, 비닐옥시모실란(Vinyl Oximeino Silane)은 겔화를 촉진하고 무기물의 균일분산성 및 성형안정성을 제공하며, 제올라이트 미분은 알루미늄 규산염 광물의 일종으로서 대표적인 원적외선 방사물질이자 이온교환성을 갖는 물질이며, 탈취, 정화 특성을 발현시키기 위해 첨가된다.At this time, vinyl oxymosilane (Vinyl Oximeino Silane) promotes gelation and provides uniform dispersibility and molding stability of inorganic matter, and zeolite fine powder is a kind of aluminum silicate mineral, which is a representative far-infrared radiation material and a material having ion exchange properties, and deodorization , Is added to express the purification properties.

그리고, 벤조구아나민은 정전기 방지 특성을 유지하면서 부착력 안정화를 유지하기 위해 첨가된다.In addition, benzoguanamine is added to maintain adhesion stabilization while maintaining antistatic properties.

이러한 구조를 갖는 상지층(300)이 합지된 기재(100)는 두 개의 롤러, 즉 하부의 고무롤러와, 이에 맞물려 있고 표면에 다수의 미세요철이 형성되어 있으며 150℃까지 가열되는 상부의 철롤러 사이로 통과되면서 상지층(300)을 구성하는 PVC 필름(330)의 표면이 미세요철에 대응하여 살짝 용융되면서 거칠기게 형성된다.The substrate 100 on which the upper layer 300 having such a structure is laminated is two rollers, that is, a rubber roller at the bottom, and an iron roller at the top that is meshed with and has a plurality of fine concave and convex formed on the surface and heated to 150°C. As it passes through, the surface of the PVC film 330 constituting the upper layer 300 is slightly melted in response to the fine concavo-convex and is formed to be rough.

이를 통해, 무광처리가 가능하게 된다.Through this, matting treatment is possible.

즉, 기존에는 PET 기재만으로 되었기 때문에 열롤러를 통한 무광처리가 어려웠지만, 본 발명에서는 무광처리가 가능한 PVC 필름을 PET 기재에 합지하여 사용하기 때문에 무광처리가 가능하게 된 것이다.That is, in the past, matting treatment through a heat roller was difficult because only a PET substrate was used, but in the present invention, a matte treatment is possible because a PVC film capable of matting treatment is laminated to a PET substrate.

다만, PVC 필름을 PET 시트에 합지하는 것이 매우 어렵기 때문에 본 발명의 독특한 처리 방식을 통해 이를 가능하도록 구현하였고, 이를 바탕으로 무광처리할 수 있도록 한 것이 특징이다.However, since it is very difficult to laminate the PVC film to the PET sheet, it has been implemented to make this possible through the unique treatment method of the present invention, and it is characterized in that it can be matted based on this.
