산화마그네슘을 이용한 건자재 성형방법{building materials molding metod used magnesium oxide}Building material molding method using magnesium oxide

본 발명은 산화마그네슘을 이용한 건자재 성형방법에 관한 것으로, 특히 가열히터가 내장된 사출금형으로 산화마그네슘을 주재료로 한 혼합물을 성형한 후 열을 가하여 신속하게 경화시킬 수 있도록 하고, 또 양면성형 및 정밀성형이 가능하며, 제조 공정수와 제품의 제조시간을 최대한 줄여 저렴한 비용에 높은 생산성을 얻을 수 있도록 한 산화마그네슘을 이용한 건자재 성형방법에 관한 것이다.The present invention relates to a method for forming a dry material using magnesium oxide, and in particular, an injection mold with a heating heater to mold a mixture made of magnesium oxide as a main material, so that it can be quickly cured by applying heat, and double-sided molding and precision The present invention relates to a method for forming a dry material using magnesium oxide, which is capable of molding and obtains high productivity at a low cost by minimizing the number of manufacturing processes and manufacturing time of a product.

일반적으로 건축물은 크게 골조와 내외장재로 구분하는 바, 골조로 사용되는 건축자재로는 건물의 대상에 따라 다를 수 있지만, 대표적으로 철근 콘크리트, 철골, 목재, 벽돌 등을 들 수 있고, 내외장재는 석고, 목재, 합성수지, 우레탄폼 등으로 구분할 수 있다.In general, buildings are classified into frame and interior and exterior materials, but the building materials used as a frame may vary depending on the object of the building. Representative examples include reinforced concrete, steel, wood, brick, etc. It can be divided into wood, synthetic resin and urethane foam.

골조와 내, 외장재는 안전을 위해 건물의 하중과 외부로부터의 충격을 견딜 수 있는 강도와 내부식성, 내열, 내연성, 단열성 등의 조건을 충족시켜야 한다.Frames, interior and exterior materials are required to meet the requirements of strength, corrosion resistance, heat resistance, flame resistance, insulation, etc. to withstand the load of the building and external shocks for safety.

많은 화재사고에서도 알 수 있듯이 내연성의 중요성은 널리 알려져 있는데, 대부분의 건자재는 내연성을 가지더라도 한계점 이상의 열을 받게되면 연소가 될 뿐만 아니라 유독가스를 발산하여 화재사고시 질식사의 원인이 되는 등 안전성에 문제가 있었다.As can be seen from many fire accidents, the importance of flame resistance is widely known. Although most materials have a flame resistance, they are not only burned when they receive heat above the threshold, but they also emit toxic gases and cause asphyxiation in fire accidents. There was.

특히 합성수지 제품에서 이러한 현상들이 많이 발생하고 있다.In particular, many of these phenomena occur in synthetic resin products.

이러한 사고를 예방하기 위해 현재 건자재의 선택시 안전 조건을 만족시킬 수 있도록 건축법에서도 그 규제를 강화하고 있는 실정이다.In order to prevent such an accident, the building law is strengthening its regulations to satisfy safety conditions when selecting construction materials.

상술한 바와 같은 조건을 충족시켜주는 건자재들이 많이 있는데, 본 발명이 다루고자 하는 건자재로는 산화마그네슘이 있으며, 이 산화마그네슘에 톱밥 등과 같은 식물성 재료를 첨가하여 양생시키면 훌륭한 건자재로 활용할 수가 있는데, 불연성 재질이기 때문에 화재시에도 안전하고 또 유독가스를 전혀 발생하지 않는 특징이 있을 뿐만 아니라 강도가 강한 장점이 있다.There are many building materials that satisfy the conditions as described above, and the building materials to be dealt with by the present invention include magnesium oxide, which can be used as an excellent building material when cured by adding vegetable materials such as sawdust to magnesium oxide. Because it is a material, it is safe in fire and does not generate toxic gas at all, and it has strong strength.

건자재를 성형함에 있어서도, 일반 건자재 성형물은 경화제로서 염화물을 혼합하여 성형하였으나, 염화물의 대기중의 습기를 빨아들이는 조해성(潮解性) 때문에 표면이 끈적끈적함을 느끼게 되는 결점이 있었다.In molding dry materials, the general dry material moldings were formed by mixing chloride as a curing agent, but there was a drawback that the surface became sticky due to the deliquescent property of sucking moisture in the air of the chloride.

이 때문에 본 발명이 취급하고자 하는 건자재는 경화제 즉, 염화물의 사용을배제하여 일반 건자재 성형물이 가지고 있는 결점을 완전히 극복한 장점이 있다.For this reason, the construction material to be handled by the present invention has the advantage of completely overcoming the drawbacks of the general building material molding by eliminating the use of a curing agent, that is, chloride.

상기한 바와 같은 종래의 건자재는 콘크리트를 성형틀에 주형하여 몰딩성형하는 방법과 같이 소재에 톱밥 등을 물과 혼합하여 믹싱하여 여러 개의 형틀에 각각 주입한 다음 적정한 상온을 유지하는 양생실에 운반하여 콘크리트를 양생하는 방법과 같이 일정한 시간을 양생한 다음 탈형하는 순서로 제품을 생산한다.Conventional building materials as described above are mixed with water and sawdust and mixed with water, such as a method of molding and molding concrete in a molding mold, and injected into a plurality of molds, respectively, and then transported to a curing room maintaining a proper room temperature Produce products in the order of curing after demolishing a certain time like the method of curing concrete.

단순 몰딩성형으로 건자재를 성형함에 따라 노동력에 의존하는 여러 공정을 거치기 때문에 많은 시간과 노동력이 소요되고, 또한 자연건조에 따른 경화 그에 따른 많은 제조비용이 낭비될 뿐만 아니라 생산성이 떨어지는 폐단이 있었다.As the molding material is molded by simple molding, it takes a lot of time and labor because it goes through various processes depending on the labor force, and also wastes a lot of manufacturing cost due to hardening due to natural drying, and also has a disadvantage of low productivity.

또한, 상기한 바와 같은 건자재 성형방법은 양면성형이 이루어지지 않아 일면성 제품에만 적용해야 하고, 또 정교한 제품에는 적용하지 못하는 제약이 있었다.In addition, the building materials forming method as described above should not be applied to one-sided products because the double-sided molding is not made, there was a restriction that can not be applied to sophisticated products.

하지만, 상기한 바와 같은 건자재 방법들은 제품생산시 재료를 믹싱하여 형틀에 붇고 이를 양생실로 운반하여 적재시키고 자연건조로 양생시킨 후 다시 운반하여 탈형하는 등 불필요한 여러 공정을 거쳐야 하기 때문에 많은 시간이 소요될 뿐만 아니라 이러한 공정들을 모두 노동력을 이용하도록 되어 있어 많은 인력과 그에 따른 인건비가 소요될 뿐만 아니라 생산성이 떨어지는 폐단이 있었다.However, as described above, the building materials methods take a lot of time because they have to go through various processes such as mixing materials in the production of the product, placing them in a mold, transporting them to a curing room, loading them, curing them in natural drying, and transporting them again and demolding them. In addition, all of these processes are required to use the labor force, which not only requires a lot of manpower and labor costs, but also results in poor productivity.

또한, 상기한 바와 같은 건자재 성형방법은 양생공정의 특성상 양면성형이 이루어지지 않아 일면성 제품에만 적용해야 하고, 또 정교한 제품 생산에는 적용하지 못하는 제약이 있었다.In addition, the dry material molding method as described above has to be applied only to one-sided products because the double-sided molding is not performed due to the nature of the curing process, and there was a limitation that cannot be applied to the production of sophisticated products.

이와 같이 본 발명이 취급하고자 하는 산화마그네슘은 건축자재로서의 높은장점을 많이 가지고 있음에도 불구하고, 상술한 바와 같이 노동력을 필요로 하는 단순 몰딩성형에 의존하는 등 제조 및 성형방법의 미개발에 의해 활성화되지 못하고 있는 실정이다. 이는 건자재 성형은 몰딩성형으로만 제조할 수밖에 없다는 고정관념도 큰 역할을 했다고 볼 수 있다.Thus, although the magnesium oxide to be handled by the present invention has many advantages as building materials, it cannot be activated by undeveloped manufacturing and molding methods, such as relying on simple molding that requires labor as described above. There is a situation. It can be said that the stereotype that construction material molding can only be manufactured by molding molding also plays a big role.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로써, 고온에서도 잘 타지 않는 불연성을 가지는 산화마그네슘을 주재료로 한 건자재를 제공하기 위한 것으로써, 정밀한 성형이 가능하고, 제조 공정수와 제품의 제조시간을 최대한 줄여 저렴한 비용에 높은 생산성을 얻을 수 있으며, 양생을 위한 운반공정과 같은 불필요한 공정을 최대한 줄이고, 또한 공정을 수행하는데 필요한 시간을 최소로 하여 적은 작업인원으로도 최대의 생산성을 향상시킬 수 있도록 한 산화마그네슘을 이용한 건자재 성형방법을 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in order to solve the problems described above, and to provide a building material mainly composed of magnesium oxide having a non-flammability that does not burn well even at high temperatures, it is possible to precise molding, manufacturing process High productivity can be achieved at a low cost by minimizing the number and time of manufacture of the product, minimizing unnecessary processes such as transportation process for curing, and minimizing the time required to carry out the process. It is an object of the present invention to provide a method for forming dry materials using magnesium oxide to improve productivity.

상기한 목적을 달성하기 위한 본 발명에 따른 산화마그네슘을 이용한 건자재 성형방법은 산화마그네슘을 별도의 식물성 재질과 배합하여 몰탈과 같은 상태의 배합물을 얻는 공정과; 사출금형을 형합하고 주입구를 통해 상기 배합물을 금형내로 고압으로 주입하는 성형공정과; 성형공정시 또는 성형공정 후 금형내에 설치된 히터에 열을 가하여 경화시키는 공정 및; 경화공정에 의해 경화되면 금형으로부터 탈형하는 공정으로; 구성함을 특징으로 한다.Drying material forming method using magnesium oxide according to the present invention for achieving the above object is a step of obtaining a compound in the state such as mortar by combining magnesium oxide with a separate vegetable material; A molding process of molding the injection mold and injecting the compound at a high pressure into the mold through an injection hole; A step of applying heat to a heater installed in the mold during the molding process or after the molding process to cure; A step of demolding from a mold when cured by a curing step; It is characterized by the configuration.

이 도면에 도시된 바와 같이, 본 발명에 따른 산화마그네슘을 이용한 건자재 성형방법은 산화마그네슘을 별도의 식물성 재질과 배합하여 몰탈과 같은 상태의 배합물을 얻는 공정과; 사출금형을 형합하고 주입구를 통해 상기 배합물을 금형내로 고압으로 주입하는 성형공정과; 성형공정시 또는 성형공정 후 금형내에 설치된 히터에 열을 가하여 경화시키는 공정 및; 경화공정에 의해 경화되면 금형으로부터 탈형하는 공정으로; 구성한다.As shown in this figure, the method for forming a building material using magnesium oxide according to the present invention comprises the steps of: combining magnesium oxide with a separate vegetable material to obtain a compound in a mortar-like state; A molding process of molding the injection mold and injecting the compound at a high pressure into the mold through an injection hole; A step of applying heat to a heater installed in the mold during the molding process or after the molding process to cure; A step of demolding from a mold when cured by a curing step; Configure.

여기서, 본 발명에 따른 산화마그네슘을 이용한 건자재 성형방법은 건축자재의 소재로 산화마그네슘을 이용하여 건자재로 제품화하고자 할 때에는 산화마그네슘에 톱밥이나 작은 입자형태의 식물성 소제를 물과 함께 적당한 배합비로 믹싱한다.Here, in the dry material forming method using magnesium oxide according to the present invention, when manufacturing a dry material using magnesium oxide as a building material, vegetable flour in the form of sawdust or small particles in magnesium oxide is mixed with water at an appropriate mixing ratio. .

믹싱공정을 거친 배합물은 용도에 따라 사출기로 압력을 가하면서 성형한다.The blended compound is molded under pressure with an injection machine, depending on the application.

성형된 성형물은 열을 가하여 양생시키는 공정을 거치며, 양생되어 경화되면 탈형공정을 거쳐 제품이 완성된다.The molded product is subjected to a curing process by applying heat, and when cured and cured, the product is completed through a demolding process.

특히, 사출에 의해 제품을 성형할 경우에는 사출금형에 히터를 장착하여 배합물을 주입구로 주입하면서 히터의 열을 가하여 경화시키거나 또는 주입완료 후 열을 가하여 경화시켜 성형한 후 탈형시키는 순서로 제조한다.In particular, when molding a product by injection, the heater is mounted on the injection mold, and the compound is injected into the inlet to be cured by applying heat of the heater or by applying heat after completion of injection to form the mold and then demolding. .

상기한 사출기를 이용하여 제품을 생산함에 있어서는 도 1에 도시된 바와 같이, 산화마그네슘 혼합물을 사출하는 금형은 사출금형의 내부에 히터(12)를 내장한것에 특징이 있으며, 상기 사출금형은 양면성형이 가능하도록 상·하부금형(10a)(10b)으로 구성되며, 일측에는 재료를 고압으로 주입하는 주입구(11)가 형성된다.In the production of the product using the injection machine as shown in Figure 1, the mold for injecting the magnesium oxide mixture is characterized in that the heater 12 is embedded in the injection mold, the injection mold is a double-sided molding It is composed of upper and lower molds (10a) (10b) to enable this, one side is formed with an injection port 11 for injecting the material at a high pressure.

또한, 상기 상·하부금형(10a)(10b)을 이루는 벽체의 내부에는 히터(12)가 내장된다.In addition, a heater 12 is embedded in the wall of the upper and lower molds 10a and 10b.

이때 주입구(11)부분에는 주입되는 수지가 경화되는 것을 방지하기 위해 가능한 히터(12)의 열이 전달되지 않도록 하는 것이 바람직하다.At this time, it is preferable that the heat of the heater 12 is not transmitted to the injection hole 11 to prevent the resin to be injected from being cured.

상기한 바와 같은 구조의 금형에 믹싱된 소재를 주입하기전 상·하부금형(10a)(10b)에 장착된 히터(12)를 가동하여 설정된 온도로 가열시킨 다음 소재를 고압으로 주입한다.Before injecting the mixed material into the mold having the structure described above, the heater 12 mounted on the upper and lower molds 10a and 10b is operated to be heated to a set temperature, and then the material is injected at high pressure.

주입된 소재는 소정시간이 지나면 열에 의해 신속하게 경화되므로 곧바로 금형을 형개하여 탈형할 수가 있다.The injected material is quickly cured by heat after a predetermined time, so that the mold can be immediately opened and demolded.
