발포시트 제조과정은 혼련, 배합, 압출, 모판성형, 발포, 냉각 및 권취공정으로 구성되는데, 종래에는 기능성을 발현하기 위해 각종 첨가제들을 혼련, 배합 또는 압출공정에서 투입하게 되는데 이 경우 첨가제가 발포체 내부에 함침됨으로 제기능이 현저히 감소하게 되고, 이들 첨가제는 발포과정에서 각종 트러블을 발생시키는 단점이 있고, 발포배율 및 셀의 균일도 저하 등과 같은 문제점을 야기하고 있다. Foam sheet manufacturing process consists of kneading, blending, extrusion, plate forming, foaming, cooling, and winding process, and conventionally, various additives are added in a kneading, blending, or extrusion process to express functionality. Impregnated in to significantly reduce the function, these additives have the disadvantage of causing various problems in the foaming process, causing problems such as foaming ratio and cell uniformity decrease.
특히 탈취 또는 항균 등 직접적인 접촉에 기능이 발휘되는 경우에 있어서는 더욱 그러하다. 따라서, 원적외선 방사기능과 같이 내부에 함침시킴에도 불구하고 기능의 손실이 적은 경우를 제외하고는 기능성 소재들을 외부 표면에 노출시킴으로서 기능을 활성화시킬 수 있는 제품의 구조와 그 제조방법이 요구된다.This is especially the case when the function is exerted on direct contact such as deodorization or antibacterial. Therefore, there is a need for a structure of a product capable of activating a function by exposing functional materials to an external surface except for a small loss of function despite impregnation therein, such as a far infrared radiation function.

And a mixture of a substance (B2) having micropores to which one or more antimicrobial substances (C) selected from photocatalyst titanium dioxide and silver (Ag) are impregnated is applied to the foam sheet (D) surface layer.
이때, 상기 미세공을 갖는 물질(B)은 활성탄, 제올라이트, 일라이트로 이루어지는 군으로부터 단독 또는 혼합 사용되며, 또한 금속촉매(A)가 첨착된 미세공을 갖는 물질(B1)과 항균성 물질(C)이 첨착된 미세공을 갖는 물질(B2)의 혼합물(B1+B2)이 발포시트(D) 표층에 도포되는 기능성 발포시트의 제조방법에 있어서, 혼련, 배합, 압출, 모판성형, 발포, 냉각 및 권취공정으로 이루어지는 발포시트(D)의 제조공정 중 압출기로부터 연속적으로 공급되는 고온의 모판 표층에 상기 혼합물(B1+B2)을 직접 분사한 후 모판성형로라를 통과시켜 발포됨으로써 별도의 접착제 없이 용이하게 도포되어지는 것을 그 기술적 방법상의 기본 특징으로 한다. In this case, the material (B) having the micropores is used alone or mixed from the group consisting of activated carbon, zeolite, and illite, and also the material (B1) and the antimicrobial material (C1) having the micropores to which the metal catalyst (A) is impregnated.

도1 내지 도3에서 도시한 바와 같이, 본 발명의 기능성 발포시트는 금속촉매(A)가 첨착된 미세공을 갖는 물질(B1)과 항균성 물질(C)이 첨착된 미세공을 갖는 물질(B2)의 혼합물이 발포시트(D) 표층에 도포되어 이루어진다.As shown in Figures 1 to 3, the functional foam sheet of the present invention is a material (B1) having a micropore to which a metal catalyst (A) is impregnated and a material having a micropore to which an antimicrobial material (C) is impregnated (B2). ) Is applied to the foam sheet (D) surface layer.
상기 미세공을 갖는 물질(B)은 활성탄(activated carbon), 제올라이트(zeolite), 일라이트(illilite) 중에서 선택된 1종 이상을 사용하며, 본 발명의 기능성 발포시트가 적용되는 분야와 목적하는 바에 따라 상기 물질들의 고유한 특성들을 고려하여 선택되어진다.The material (B) having the micropores uses at least one selected from activated carbon, zeolite, and illilite, and according to the field and purpose to which the functional foam sheet of the present invention is applied. The unique properties of the materials are taken into account.
활성탄은 야자각, 목재류, 갈탄, 무연탄, 유연탄 등의 탄소질을 원료로 하여 활성화 과정을 통해 분자크기 정도의 미세세공을 발달시킨 물질로서 1g당 1000㎡ 내외의 큰 내부 표면적을 가지며, 유해물질의 흡착제거능력이 뛰어나고, 제올라이트는 장석류 광물의 일종으로서, 내부에 있는 나노 크기의 세공을 가지며, 항균효과와 소취력이 탁월한 점에서 많은 분야에서 활용되고 있다. 일라이트는 유해물질에 대한 우수한 흡착탈취분해력, 상온에서의 높은 원적외선 방사와 음이온 발생능력, 바이러스, 박테리아, 곰팡이 등의 항균기능을 가진다.Activated carbon is made of carbonaceous materials such as coconut shell, wood, lignite, anthracite and bituminous coal. The activated carbon has developed micropores of molecular size through activation process and has a large internal surface area of about 1000㎡ per gram. It has excellent adsorption and removal ability, and zeolite is a kind of feldspar mineral, which has nano-sized pores inside, and has been used in many fields because of its excellent antibacterial effect and deodorizing power. Illite has excellent adsorption and deodorization ability against harmful substances, high far-infrared radiation and anion generating ability at room temperature, and antibacterial functions such as viruses, bacteria and fungi.
본 발명의 특징 중 하나는 상기 미세공을 갖는 물질(B)에 금속촉매(A)와 항균성 물질(C)을 첨착하여 사용하는 것이다.One of the characteristics of the present invention is to use the metal catalyst (A) and the antimicrobial material (C) by attaching the microporous material (B).
미세공을 갖는 물질-활성탄, 제올라이트, 일라이트-은 잘 발달된 미세공으로 인해 흡착탈취기능을 갖는데 이 미세공은 한정된 공간을 가지므로 시간 경과에 따른 일정량 이상의 흡착이 이루어지면 더 이상의 기능을 발휘할 수 없게 된다. 따라서 본 발명에서는 금속촉매를 미세공을 갖는 물질(B)에 첨착하여 사용함으로써 미세공을 갖는 물질이 유해물질을 흡착하고 금속촉매에 의해 분해가 이루어지게 함으로써 장시간 효과가 지속될 수 있다. 한편, 본 발명의 금속촉매나 항균성 물질은 그 입자가 미세하여 사전에 미세공을 갖는 물질에 첨착하지 않으면 도포시 효율이 크게 떨어지고 각 물질의 상호작용 내지는 상승효과를 기대하기 힘들다.Substances with fine pores-activated carbon, zeolite, and illite-have an adsorption deodorization function due to the well-developed micropores. Since the micropores have a limited space, they can perform more functions when a certain amount of adsorption is achieved over time. There will be no. Therefore, in the present invention, the metal catalyst is attached to the microporous material (B), so that the microporous material adsorbs harmful substances and is decomposed by the metal catalyst. On the other hand, the metal catalyst or the antimicrobial material of the present invention is very difficult to expect the interaction or synergistic effect of each material and the efficiency is greatly reduced when the particles are fine and do not adhere to the material having fine pores in advance.
항균성 물질(C)은 광촉매 이산화티탄(TiO2) 또는 은(Ag) 중에서 단독 또는 혼합 사용하며, 본 발명에서는 유기계 항균성 물질은 배제하고 있으며 이는 유기계가 열에 약하고 분해하기 쉬워 지속력이 떨어지는 점과 제조공정상 고온(200℃ 내외)의 발포공정을 포함함으로 사용이 불가하다. 다만, 도 5에서 도시한 바와 같이 발포공정후 발포시트(D) 표면에 접착 처리 후 도포하는 경우에 있어서는 유기계 항균성 물질의 사용을 고려할 수 있게 된다.The antimicrobial material (C) is used alone or in a mixture of photocatalyst titanium dioxide (TiO 2 ) or silver (Ag). In the present invention, the organic antimicrobial material is excluded, which is weak in heat and easy to decompose, and thus has low sustainability. It cannot be used because it includes foaming process of high temperature (about 200 ℃). However, as shown in FIG. 5, in the case of applying after the adhesive treatment to the surface of the foam sheet (D) after the foaming process, the use of an organic antimicrobial substance may be considered.
광촉매 이산화티탄은 기본적으로 항균기능을 비롯하여 탈취 및 유기물의 산화분해기능을 가지며, 이는 광촉매 반응시 생성되는 정공(h+)이 수산기(-OH)와 반응을 일으켜 생성되는 수산라디칼(OH) 전자(e-)에 의해 생성되는 슈퍼옥사이드 음이온이 표면에 생성되어 대상물질을 산화시키는 능력이 매우 우수하기 때문이다. Photocatalyst titanium dioxide basically has antibacterial function, deodorization and oxidative decomposition function of organic matter, which is radical radical (OH) electron (e) produced by reaction of hydroxyl (-OH) with hole (h +) produced during photocatalytic reaction This is because the superoxide anion produced by-) is formed on the surface and the ability to oxidize the target material is very good.
또한, 은(Ag)은 내열성, 안정성 및 가공성이 우수한 항균제이다. 은이 항균력을 가지는 이유는 미생물의 세포표면을 구성하는 막단백질 구조의 일부인 SH기에 은 원자와 일시적으로 결합한 산소 원자가 반응하여 막단백질의 구조에 영향을 주게 되어 생육과 번식을 억제함으로 발현된다.In addition, silver (Ag) is an antibacterial agent excellent in heat resistance, stability, and workability. The reason why silver has antimicrobial activity is expressed by SH group, which is a part of membrane protein structure constituting cell surface of microorganism, and oxygen atom which is temporarily bonded with silver atom affects the structure of membrane protein, thereby inhibiting growth and reproduction.
본 발명의 또 다른 특징은 내열난연성을 부여하는 것이다. 본 발명의 기능성 혼합물은 광물 또는 금속계로부터 유래된 것으로, 도포에 의해 발포시트의 표층을 코팅함으로써 합성수지로 이루어진 발포시트의 취약점인 내열난연성이 크게 향상하게 된다.Another feature of the present invention is to impart heat resistance flame resistance. The functional mixture of the present invention is derived from a mineral or metal system, and by coating the surface layer of the foam sheet by application, heat resistance, which is a weak point of the foam sheet made of synthetic resin, is greatly improved.
