본 발명은 UV 차단코팅제, 이를 이용하여 오염을 방지하는 UV 차단코팅층이 형성된 매트와 이를 제조하는 방법에 관한 것이다.The present invention relates to a UV blocking coating agent, a mat having a UV blocking coating layer for preventing contamination using the same, and a method for manufacturing the same.
일반적으로 가정이나 유치원, 어린이집 혹은 체육관이나 각종 운동시설을 갖춘 실내에는 충격이나 부상을 방지하는 동시에 층간 소음 등을 감소시키기 위한 바닥 매트를 깔아 사용하게 된다.In general, a floor mat for preventing shock or injury and reducing noise between floors is used in homes, kindergartens, daycare centers, gymnasiums, or indoors equipped with various exercise facilities.
이와 같은 바닥 매트는 통상적으로 우레탄 발포 성형방법을 통해 만들어지는 것으로 발포 성형 매트 자체의 우수한 탄력성 및 완충성으로 인해 부상 방지 및 소음 감소가 이루어지는 것이고, 상기와 같이 발포 성형되는 바닥 매트의 표면에는 다양한 종류 및 색상 혹은 재질로 된 표피재를 함께 부착하여 만들어지는 것으로, 바닥 매트의 사용 목적이나 사용 용도 혹은 설치 장소에 따라 적합한 형태의 두께나 무늬 혹은 장식 패턴 등이 형성된 제품을 선택 사용하게 된다.Such a floor mat is usually made through a urethane foam molding method, and injury prevention and noise reduction are achieved due to the excellent elasticity and buffering property of the foam molded mat itself. It is made by attaching skin materials of color or material together, and a product formed with a suitable thickness, pattern, or decorative pattern is selected and used according to the purpose of use, use, or installation location of the floor mat.
이러한 바닥매트는 실용신안등록 제20-0430351호와 같이, 무가교 PE 발포수지의 밑면에 PE수지를 코팅하여 엠보싱을 형성하고 무가교 PE발포수지의 윗면에는 PP부직포를 액상수지로 접착하여 보온 및 단열효과가 우수하면서, 촉감과 통기성이 양호하며, 생산성이 높은 등의 효과가 있도록 한 실내외용 매트가 등록된 바 있다.As shown in Utility Model Registration No. 20-0430351, this floor mat forms embossing by coating PE resin on the underside of non-crosslinked PE foamed resin, and adheres PP non-woven fabric with liquid resin to the upper surface of non-crosslinked PE foamed resin to keep warm and Mats for indoor and outdoor use have been registered that have effects such as excellent insulation effect, good touch and air permeability, and high productivity.
또한, 등록특허 제10-1510270호와 같이 바닥매트의 하부면에 직물재가 구비됨으로써 바닥 난방시 바닥매트로부터 유해물질이 발생되는 것이 방지되며, 이웃하는 바닥매트의 직물재 상에 벨크로부재가 동시에 부착되어 양측 바닥매트가 다양한 형태로 연결될 수 있으며, 직물재 또는 벨크로부재에 다수의 미끄럼방지 돌기가 돌출 구비되어 있어 직물재로 인해 바닥매트가 미끄러지는 것이 방지될 수 있도록 한 직물재가 구비된 바닥매트가 등록된 바 있다.In addition, as in Registered Patent No. 10-1510270, the lower surface of the floor mat is provided with a fabric material, so that harmful substances are prevented from being generated from the floor mat during floor heating, and the Velcro member is simultaneously attached to the fabric material of the adjacent floor mat. So, the floor mats on both sides can be connected in various forms, and a number of non-slip protrusions are provided on the fabric or Velcro member to prevent the floor mat from slipping due to the fabric. have been registered
이러한 기존의 바닥 매트의 경우 발포성형층의 표면 보호 및 다양한 색감과 형상을 연출하기 위한 표피재 혹은 표면재가 상기 발포성형층으로부터 분리되는 경우가 빈번하게 발생하여 바닥 매트의 사용 수명을 단축시키는 원인으로 작용하고 있다. 즉, 기존의 바닥 매트는 발포성형층의 두께에 대응하는 탄력성 대비 표면재의 탄력성이 떨어지므로 탄력성 차이에서 발생하는 신축 오차로 인해 상호 간의 접착부에서 지속적이고 강력한 부하가 작용하게 되므로 결국 표면재가 쉽게 들뜨거나 벌어지는 등의 문제점을 가지고 있다.In the case of such existing floor mats, the surface material or surface material for protecting the surface of the foamed molded layer and creating various colors and shapes is frequently separated from the foamed molded layer, which shortens the lifespan of the floor mat. It's working. In other words, since the elasticity of the surface material of the existing floor mat is lower than the elasticity corresponding to the thickness of the foamed molding layer, a continuous and strong load is applied to the mutual bonding part due to the expansion error caused by the difference in elasticity, so the surface material is easily lifted or There are problems with opening etc.
상기와 같이 표면재가 들뜨거나 벌어지는 원인은 표면재와 발포성형층의 재질이 상이하여 상호 간의 접착력이 약화되기 때문인 것으로, 폴리에틸렌 계열의 표면재를 성형 금형 내부에 삽입한 상태에서 폴리우레탄 계열의 발포층을 성형하는 경우 발포성형층이 표면재에 완전하고 견고하게 접착되지 못하므로 결국 장시간 사용이 상기의 표면재가 벌어지거나 들뜨게 된다. 그리고, 발포성형층은 많은 기공이 형성되어 있어서, 개방된 기공이나 기공간 통로를 통해 수분뿐만 아니라, 외부 오염물질이 유입되어 매트가 오염되고, 곰팡이 등이 번식하여 비위생적이어서 영아, 유아의 건강을 해치는 문제가 있다.The reason why the surface material is lifted or widened as described above is that the materials of the surface material and the foamed molding layer are different and the adhesive strength between them is weakened. In the case of this, the foamed molding layer is not completely and firmly adhered to the surface material, so that the surface material is opened or lifted after a long time of use. In addition, since the foamed molding layer has many pores, not only moisture but also external contaminants flow in through the open pores or pore passages, contaminating the mat, and mold and the like propagate, which is unsanitary and harms the health of infants and young children. There is a problem with harm.

At this time, if the melting point is less than 160 ° C., there may be a problem of insufficient heat resistance of the mat. In the present invention, the TPU film layer is excellent in yellowing resistance due to improved heat resistance, improved weather resistance and durability, and UV blocking effect of the mat, and the TPU film layer has a thickness of less than 0.2 mm, preferably a thickness of 150 to 200 μm, more preferably is preferably formed to have a thickness of about 150 to 180 μm. At this time, if the thickness of the TPU film layer exceeds 200 μm, curl (curvature) may occur due to a problem of elasticity between the foam layer and the base layer, and the interlayer between the foam layer and the base layer (and/or the printed layer) during use. There may be a peeling problem, and if the thickness of the TPU film layer is too thin, the effect of improving heat resistance, weather resistance, and durability may be insufficient.
다음으로, 4단계의 UV 차단코팅층은 매트 표면에 내오염성, 방수성, 항균성을 부여하는 역할을 하는 것으로서, UV 차단코팅제로 코팅 및 건조시켜서 형성시킬 수 있다.Next, the UV blocking coating layer of the fourth step serves to impart stain resistance, waterproofness, and antibacterial properties to the surface of the mat, and may be formed by coating and drying with a UV blocking coating agent.
