본 발명은 황토 함유 폴리우레탄 발포체 및 이의 제조방법에 관한 것으로, 좀 더 구체적으로는 폴리우레탄 발포체를 제조함에 있어서 사용되는 폴리에스테르 또는 폴리에테르계의 폴리올의 중량비로 10 ∼ 40%의 황토를 첨가하여 제조한 황토 함유 폴리우레탄 발포체 및 이의 제조방법에 관한 것이다.The present invention relates to an ocher-containing polyurethane foam and a method for manufacturing the same, and more particularly, by adding 10 to 40% of ocher in a weight ratio of a polyester or polyether-based polyol used in preparing a polyurethane foam. It relates to a manufactured ocher-containing polyurethane foam and a method for producing the same.
폴리우레탄 발포체는 다포성 또는 스폰지형의 폴리우레탄 수지로 폴리에스테르 또는 폴리에테르계 폴리올과 2관능 또는 다관능의 디이소시아네이트와 발포제, 촉매 등의 원료 및 각종 첨가제와 혼합반응시키면 중부가 가교반응이 일어나고, 발열하여 수지화된 것으로, 반응의 진행중에 발생하는 이산화탄소 때문에 발포 다공질이 되며, 기게적 강도도 크고, 내열성, 내용제성, 내노화성, 접착성이 양호하며, 원료조건을 택하는 것에 의해 상당히 연질탄력성이 있는 것에서 경질 내마모성의 것까지 제조되고 그 경도에 의해 연질, 반경질, 경질의 3종류로 나누어진다. 연질발포체는 자동차 등의 쿠숀재, 충진재, 필터용 등으로 사용되고 있고, 반경질 발포체는 열이나 전기의 절연재료로, 경질 발포체는 가볍고, 탄성이 적으며, 하중부담능력이 크고 단열성도 우수하여 항공기 및 기계부품재료, 공업용 및 가정용 단열재료와 방음판 등으로 널리 이용되고 있다.Polyurethane foams are polyporous or sponge-type polyurethane resins. When poly- or polyether-based polyols are mixed with di- or polyfunctional diisocyanates, raw materials such as blowing agents, catalysts, and various additives, a polyaddition crosslinking reaction occurs. It is made of exothermic resin by heating and becomes foamed porous due to carbon dioxide generated during the reaction. It has high mechanical strength, good heat resistance, solvent resistance, aging resistance and adhesiveness, and is very soft by selecting raw material conditions. It is manufactured from elastic to hard abrasion resistant and is divided into three types of soft, semi-hard, and hard by its hardness. Soft foams are used for cushions, fillers, filters, etc. in automobiles, and semi-rigid foams are insulation materials of heat and electricity. Rigid foams are light, low in elasticity, have high load-bearing capacity and excellent thermal insulation. And it is widely used as a mechanical component material, industrial and household insulation material and sound insulation board.
그러나, 폴리우레탄 발포체는 사용 용도에 따라 요구되는 특성이 많이 있어 이를 충족시키기 위한 각종 첨가제가 첨가되고 있는 실정이지만, 여러 가지 요구 특성이 있는 경우에는 첨가제의 종류도 많아져야 하므로 경제적으로 바람직하지 못한 단점이 있고, 공정이 복잡해지며, 제조되는 폴리우레탄 발포체 자체의 특성이 저하되는 문제가 있고, 1종의 첨가제로 많은 요구 특성을 만족시킬 수 없는 단점이 있다.However, polyurethane foams have many required properties depending on the intended use, and various additives are added to satisfy them. However, if there are various required properties, the types of additives have to be increased, which is economically undesirable. There is a problem in that the process is complicated, the properties of the polyurethane foam itself is lowered, there is a disadvantage that can not satisfy many required properties with one kind of additive.

본 발명을 좀 더 구체적으로 설명하면 다음과 같다.The present invention is described in more detail as follows.
본 발명에 따른 황토 함유 폴리우레탄 발포체는 폴리우레탄 발포체를 제조함에 있어서 사용되는 폴리에스테르 또는 폴리에테르계의 폴리올의 중량비로 10 ∼ 40%의 황토를 첨가하여 제조한 것으로 특징지워진다.The ocher-containing polyurethane foam according to the present invention is characterized by being prepared by adding 10 to 40% of ocher in the weight ratio of polyester or polyether-based polyols used in producing the polyurethane foam.
또한, 황토 함유 폴리우레탄 발포체의 제조방법은 황토 채취공정, 채취된 황토로부터 이물질을 제거하고 멸균처리한 후 분쇄가공하는 공정, 미립자의 황토만을 선별하는 공정, 폴리에스테르 또는 폴리에테르계의 폴리올과 황토 미립자를 혼합하여 2관능 또는 다관능의 이소시아네이트류와 반응시키는 공정, 목적하는 형상으로 제조된 폴리우레탄 발포체를 가공하는 공정으로 구성되어진다.In addition, the manufacturing method of the ocher-containing polyurethane foam is a process for collecting ocher, removing foreign material from the collected ocher, sterilizing and then grinding, selecting only the ocher of fine particles, polyester or polyether-based polyol and ocher It consists of the process of mixing a microparticle and making it react with bifunctional or polyfunctional isocyanate, and the process of processing the polyurethane foam manufactured in the desired shape.
먼저, 황토 특유의 활성을 갖는 것으로 효능이 우수하며 약성이 가장 뛰어나고 오염되지 않은 황토를 선별하기 위하여 지표면에서 1 ∼ 2m 이상의 깊이에서 천연 황토를 엄선하여 채취한다.First of all, natural ocher is carefully selected and collected at a depth of 1 to 2 m or more from the surface of the earth in order to select ocher, which has excellent activity, excellent weakness, and uncontaminated ocher.
채취된 황토에서 육안으로 분별이 가능한 이물질을 제거한 다음, 1차 분쇄를 행하되 분쇄과정에서 황토 이외의 물질을 완전히 제거한 후에 800 ∼ 1,000℃에서 약 1시간 정도 소성하는 방법으로 멸균처리 및 유기물을 분해시키고, 2차 분쇄를 행한다. 분쇄과정에서 황토 이외의 물질을 제거하기 위해서는 황토의 분쇄가 가능한 정도만의 압력을 가하여 분쇄하고 체로 쳐서 분쇄되지 않은 물질들을 분리하는 방법으로 행하며, 소성온도가 800℃ 미만일 경우에는 유기물의 완전 분해가 이루어지지 않는 단점이 있고 1,000℃를 초과할 경우에는 경제적이지 못한 단점이 있다. 분쇄는 본 발명이 속하는 기술 분야에서 통상적으로 시용되는 분쇄기 중에서 사용 용도에 의한 분쇄 정도에 따라 적절히 선정하여 사용할 수 있다.Sterilize and decompose organic materials by removing foreign matter that can be separated by naked eye from the collected ocher, and then performing the first crushing, and completely removing other materials than ocher in the crushing process, and then firing at 800 to 1,000 ° C. for about 1 hour. Second grinding is performed. In order to remove materials other than ocher in the pulverization process, pulverization is carried out by applying pressure only to the extent of ocher crushing and sifting to separate the pulverized materials. When the firing temperature is less than 800 ° C, organic matter is completely decomposed. There is a disadvantage that does not support, and if it exceeds 1,000 ℃ there is a disadvantage that is not economic. The grinding | pulverization can be suitably selected and used according to the grinding | pulverization degree by use use from the grinder normally applied in the technical field to which this invention belongs.
그 다음에 2차 분쇄된 황토 분말을 풍향집진기를 이용하여 1 ∼ 5㎛ 정도의 크기를 갖는 미립자만을 선별한다. 즉, 2차 분쇄된 황토 분말을 공지의 풍향집진기의 투입구에 투입한 다음, 1 ∼ 5㎛ 정도의 크기를 갖는 미립자만이 이송될 수 있는 정도의 풍속으로 공기를 가하여 미립자를 이송한 후 풍속을 거의 0이 되도록 하므로서 황토 미립자만을 얻게 된다.Then, the secondary pulverized ocher powder is selected using only a wind vane to fine particles having a size of about 1 ~ 5㎛. That is, the secondary pulverized ocher powder is introduced into the inlet of a known wind deflector, and then air is applied at a wind speed such that only fine particles having a size of about 1 to 5 μm can be transferred, and then the fine air is transferred. By making it nearly zero, only ocher particles are obtained.
별도로 통상의 방법으로 폴리우레탄 발포체를 제조함에 있어서 상기에서 얻은 황토 미립자를 10 ∼ 40% 첨가하므로서 황토 함유 폴리우레탄 발포체를 얻는다. 황토 미립자의 첨가량이 10% 미만일 경우에는 본 발명에서 얻고자 하는 효과의 발현 정도가 미약하고 40%를 초과하여 첨가할 경우에는 폴리우레탄 발포체의 특성이 저하되는 문제점이 발생할 수도 있으나 사용될 폴리우레탄 발포체의 용도에 따라 황토 미립자의 사용량은 변동될 수도 있다.Separately, in preparing a polyurethane foam by a conventional method, an ocher-containing polyurethane foam is obtained by adding 10 to 40% of the ocher fine particles obtained above. When the amount of the ocher fine particles is less than 10%, the degree of expression of the effect to be obtained in the present invention is weak, and when it is added in excess of 40%, the characteristics of the polyurethane foam may be deteriorated. Depending on the application, the use amount of the fine particles may vary.
폴리우레탄 발포체의 제조시에는 폴리에스테르 또는 폴리에테르계 폴리올과 2관능 또는 다관능의 이소시아네이트류를 사용하는 것이 바람직하며, 발포가 용이하게 이루어질 수 있도록 하기 위한 발포제 및 발포보조제, 그리고 촉매 등과 제조되는 발포체에서 요구되는 특정의 요구 물성을 만족시키기 위한 공지의 첨가제들이첨가될 수 있다.In the preparation of the polyurethane foam, it is preferable to use a polyester or polyether polyol and bifunctional or polyfunctional isocyanates, and a foam prepared from a foaming agent, a foaming aid, a catalyst, etc. to facilitate foaming. Known additives may be added to satisfy the specific required physical properties required by the.
또한, 제조되는 발포체의 사용 용도에 따라 연질, 반경질, 경질의 발포체를 용이하게 제조할 수 있으며, 이는 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자이면 용이하게 유추할 수 있는 것이다.In addition, according to the use of the foam to be produced can be easily produced soft, semi-rigid, rigid foam, which can be easily inferred by those skilled in the art.
상술한 방법으로 제조된 폴리우레탄 발포체를 목적하는 형상으로 가공하므로서 본 발명에 따른 황토 함유 폴리우레탄 발포체가 제조된다.The ocher-containing polyurethane foams according to the invention are produced by processing the polyurethane foams produced in the above-described way into the desired shape.
