Description

고강도 바닥재 및 이의 제조 방법High strength flooring and its manufacturing method
본 발명은 고강도 바닥재 및 이의 제조 방법에 관한 것이다. 보다 구체적으로는 고강도 코어층(rigid layer)을 포함하고, 바닥재 각 층간의 결합 방식을 열 융착(lamination) 방식으로 하되, 여러 층을 한 번에 통합하여 열 융착하지 않고 개별 층별로 구분하여 각층을 각각 순차적으로 열 융착함으로써, 치수안정성(dimension stability), 컬링(curling) 특성 및 기계적 강도(mechanical strength)가 우수하고, 상기 층간의 결합력(adhesion)과 방수성(water proof), 평활성(smoothness)이 우수하며, 제조공정의 생산 효율이 높은 바닥재 및 이를 제조하는 방법에 관한 것이다.The present invention relates to high-strength flooring and a method of manufacturing the same. More specifically, it comprises a high-strength core layer (rigid layer), and the bonding method between the floors of each floor is a thermal lamination (lamination) method, by integrating several layers at once without separating each layer by individual layers without thermal fusion Thermally sequential thermal bonding, respectively, has excellent dimensional stability, curling properties, and mechanical strength, and excellent adhesion, water proof, and smoothness between the layers. And, it relates to a flooring material having high production efficiency of the manufacturing process and a method of manufacturing the same.
건축 마감재로서 널리 사용되는 PVC(폴리염화비닐수지) 바닥재는 최근 디자인적 요소와 더불어 친환경적이고 고강도, 고내구성에 대한 소비자의 요구를 만족시키기 위하여 단순한 마감재로서의 기능뿐만 아니라 항균, 방음, 차음, 보행감, 충격 안정성 등 다양한 기능을 갖는 제품이 선보이고 있으며, 내마모성, 내열성, 내오염성, 내약품성 등 바닥재 표면의 물성 개선과 같이 내구성이 뛰어난 제품을 위한 기술 개발이 다각도로 진행되고 있다.PVC (Polyvinyl Chloride) Flooring, widely used as a building finishing material, is not only a simple finishing material but also an antibacterial, soundproofing, soundproofing, walking comfort in order to satisfy consumers' demands for eco-friendly, high strength and high durability along with design elements. Products with various functions, such as impact stability, are being introduced, and technologies for durable products, such as improvement of physical properties of the flooring surface such as abrasion resistance, heat resistance, pollution resistance, and chemical resistance, are being developed at various angles.
일반적으로 바닥재는 다층의 시트(sheet) 또는 층(layer)에 압력이나 열을 가하여 합판하여 제조되고, 바닥재에 다양한 기능을 구현하기 위해 다양한 종류의 소재층을 추가하거나, 표면에 코팅층을 도입 또는 신규 첨가물을 배합하는 방법 등을 사용하고 있다.In general, the flooring material is manufactured by plywood by applying pressure or heat to a multilayer sheet or layer, and adding various kinds of material layers to implement various functions on the flooring material, or introducing or introducing a coating layer on the surface. The method of mix | blending an additive is used.
한편, 최근에는 인위적인 질감이나 디자인보다는 친환경적이며 자연 그대로의 느낌에 대한 선호도가 높아지면서 천연 소재가 널리 사용되고 있으며, 일반적으로 사용되는 천연 소재 중 하나가 목재이다. 그러나, 목재는 수분에 약하고, 계절별 온도 변화와 사용 기간이 지남에 따라 갈라짐, 터짐 및 변형 등으로 인해 유지보수 비용이 만만치 않을 뿐 아니라 목재 자체의 가격이 높고, 목재의 종류와 가공도에 따라 특성이 달라져 올바른 사용법을 정확하게 적용하기 어려운 한계점이 있다.On the other hand, in recent years, as the preference for environmentally friendly and natural feeling than artificial texture or design is increasing, natural materials are widely used, and one of the commonly used natural materials is wood. However, wood is weak in moisture, maintenance costs are high due to seasonal changes in temperature and usage, and the cost of the wood itself is high, and depending on the type and processing of the wood, There are limitations that make it difficult to apply the correct usage correctly.
이를 보완하고자 목재 플라스틱 복합재(WPC; Wood Polymer/Plastic Composite)가 사용되고 있으나, 목분, 필라 혹은 발포제를 부 원료로 사용하다 보니 압축강도, 충격강도 등의 기계적 강도가 열세해 지는 측면이 있다. 또한, 치수안정성이 열세하여 시공 후 사용 과정에서 온도, 습도 변화에 따른 제품 변형이 발생한다. Wood plastic composite (WPC) is used to compensate for this, but wood powder, pillar, or foaming agent is used as a secondary raw material, so mechanical strength such as compressive strength and impact strength is inferior. In addition, dimensional stability is inferior and product deformation occurs due to temperature and humidity changes during use after construction.
여기서, 제품 변형은 치수안정성이 떨어지기 때문에 발생하는 현상으로, 각 층별 치수안정성의 차이가 발생하면 최종 제품에 컬링 현상이 일어나고, 이로 인하여 시공된 바닥재가 바닥 면으로부터 분리가 일어나거나 들뜸 현상이 발생하게 된다. 또한 치수안정성이 열세하면 바닥재 틈 사이가 벌어져 오염이 발생되고, 청소가 용이하지 않다.Here, product deformation is a phenomenon that occurs because of poor dimensional stability, if a difference in the dimensional stability of each floor occurs curling phenomenon in the final product, resulting in the separation of the flooring material from the floor surface or lifting occurs Done. In addition, poor dimensional stability opens the gap between the floor coverings, causing contamination and is not easy to clean.
이러한 컬링이나 제품 변형 현상을 방지하기 위한 방법으로서, 적층 바닥재의 이면에 변형이 적은 소재로 사이징(sizing) 층을 형성하거나 제품 이면에 직포 또는 부직포를 부착하는 방법 등이 시도되고 있다. 그러나, 이 역시 컬링 현상을 효과적으로 방지할 수 없으며, 오히려 제품이 딱딱해지거나 두께가 두꺼워져 시공과 취급을 어렵게 만들고, 제품 가격이 상승하는 단점이 있다.As a method for preventing such curling or product deformation, a method of forming a sizing layer of a material with less deformation on the back surface of the laminated flooring material or attaching a woven or nonwoven fabric to the back surface of the product has been attempted. However, this also can not effectively prevent the curling phenomenon, rather the product becomes hard or thick, making the construction and handling difficult, there is a disadvantage that the product price rises.
또한, 통상적으로 다층 복합 구조의 바닥재를 제조 시, 소재나 물성이 다른 각 층들을 적층하고 접합하는 공정이 포함되고, 충분한 층간 결합력을 얻기 위해 각층 사이에 액상의 접착제를 도포한 후 각 층을 적층하고, 압착(press)한 다음, 접착제를 경화하여 고형화하는 접착/압착 방식이 주로 사용된다. 이러한 방식은 접착제를 도포하는 공정과 경화 공정 등이 추가되고 단속적인 압착 공정을 진행하게 됨으로써, 생산 공정이 복잡해지고 공정 시간이 늘어남으로써 바닥재 제조 공정의 생산 효율이 떨어진다. 이와 더불어, 과도한 접착제의 사용은 제품 표면 오염 및 바닥재 시공 후 휘발성 유기 화합물에 의한 인체에 유해한 물질이 발생할 수 있는 위험이 있다. 상기 접착/압착 방식의 낮은 제조 공정의 생산 효율을 높이기 위해 다층 복합 구조 바닥재의 각층을 한꺼번에 열 융착하는 방식을 활용하기도 하나, 각층 간의 박리강도가 떨어지며 제조 공정 조건을 철저히 관리하지 못할 경우 치수안정성도 불안정해지는 단점이 있다.In addition, when manufacturing the flooring of a multi-layer composite structure, a step of laminating and bonding each layer having different materials or physical properties is usually included, and each layer is laminated after applying a liquid adhesive between the layers to obtain sufficient interlayer bonding force. And press / press, and then the adhesive / press method of curing and solidifying the adhesive is mainly used. In this method, an adhesive coating process, a curing process, and the like are added, and an intermittent crimping process is performed, resulting in a complicated production process and an increase in process time, thereby reducing production efficiency of the flooring manufacturing process. In addition, there is a risk that excessive use of adhesives may cause harmful substances to the human body due to volatile organic compounds after product surface contamination and flooring construction. In order to improve the production efficiency of the low adhesion manufacturing process of the adhesion / compression method, a method of thermally fusion of each layer of the multilayer composite structure flooring may be used at the same time, but the peel strength between the layers is lowered, and the dimensional stability is difficult if the manufacturing process conditions are not managed thoroughly. There is a disadvantage of becoming unstable.
