Description

건축 구조물 성형을 위한 몰딩재{Molding powder for forming architectural structures}Molding powder for forming architectural structures

본 발명은 건축물 내.외장 인테리어 용도로 사용되는 몰딩재에 관한 것으로, 상세하게는 초속경 시멘트를 주재로 하는 건축 구조물 성형을 위한 몰딩재에 관한 것이다.The present invention relates to a molding material used for building interior and exterior interior use, and more particularly, to a molding material for forming a building structure mainly made of cemented carbide cement.

일반적으로 비금속제 건축 구조물 성형을 위한 몰딩재는 다양하게 개발되어 사용되고 있는데, 일예로 FRP라 불리우는 몰딩재가 개시된 바 있다. 상기 몰딩재는 물과 혼합하여 일정한 점도로 미리 설치된 몰드폼에 주입시켜 양생하고, 몰드폼을 탈형하는 것에 의해 건축물의 내.외벽 인테리어에 이용하고 있다.In general, molding materials for molding non-metallic building structures have been developed and used in various ways. As an example, a molding material called FRP has been disclosed. The molding material is mixed with water, injected into a mold foam, which is pre-set at a predetermined viscosity, and cured. The molding material is used for interior and exterior wall interior of a building by demolding the mold foam.

그러나 종래 몰딩재에 의해 성형된 조성물은 불에 약하며, 화재시 유독가스를 발생하므로 인체에 치명적일 뿐만 아니라 내구성이 약하고, 건물 외벽에 인테리어할 경우 상온에 의해 최고 5Cm까지 수축 팽창이 일어나 균일이 발생하는 등 외장 인테리어에 적합하지 못한 문제가 있었다.However, the composition molded by the conventional molding material is vulnerable to fire and generates toxic gases in case of fire, which is not only fatal to the human body but also poor in durability. There was a problem that was not suitable for the exterior interior.

본 발명의 목적은 비금속제로 화재시 유독가스의 발생을 억제하고, 내구성및 내열성에 강한 건축 구조물 성형을 위한 몰딩재를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a molding material for forming a building structure, which is made of a non-metal and suppresses the generation of toxic gases in a fire and is strong in durability and heat resistance.

상기 목적을 달성하기 위한 본 발명은 중량%로 중량%로 초속경 시멘트분말 40-60%, 증점제 분말 0.3-0.5%, 규사분말 30-45%, 수지분말5-7%, 안정화제 분말 1-3%, 섬유분말 0.3-0.5%, 세피오라이트 분말 2-4%, 원적외선 방사재 분말 15-20%를 배합하며; 배합된 분말들은 물과 혼합하여 일정한 점도로 몰드폼에 분사하여 소정시간내에 구조물을 완성시키는 것을 특징으로 하는 건축 구조물 성형을 위한 몰딩재를 제공한다.The present invention for achieving the above object by weight percent by weight percent cemented carbide powder 40-60%, thickener powder 0.3-0.5%, silica sand powder 30-45%, resin powder 5-7%, stabilizer powder 1- 3%, fiber powder 0.3-0.5%, sepiolite powder 2-4%, far infrared emitting powder 15-20%; The blended powders are mixed with water and sprayed onto a mold foam at a constant viscosity to provide a molding material for forming a building structure, which is completed by a predetermined time.

본 발명의 바람직한 실시 태양에 따르면 몰드 조성물은 초속경 시멘트 분말을 주제로 하여 여기에 증점제, 규사미분, 수지, 안정화제, 아크릴 섬유, 세피오라이트(Sepiolite) 및 원적외선 방사제를 배합하여 조성한다.According to a preferred embodiment of the present invention, the mold composition is composed of a cemented carbide cement powder, which contains a thickener, silica fine powder, resin, stabilizer, acrylic fiber, sepiolite and far-infrared radiant.

초속경 시멘트 분말은 포틀랜드 시멘트, 알루미나 시멘트, 석고를 적당하게 혼합한 것으로, 브레인 값이 5,000cm3/g 정도로 분쇄한 것으로, 여기서 포트랜드 시멘트와 알루미나 시멘트는 강도를 높이기 위한 것이고, 석고는 양생시간을 조절하기 위한 용도로 이용된다.Cemented carbide cement powder is a suitable mixture of portland cement, alumina cement and gypsum, and has a brain value of about 5,000 cm 3 / g, where portland cement and alumina cement are used for strength and gypsum is used for curing time. It is used for the purpose of adjustment.

증점제는 백색 분말로 연화점이 650-670℃을 유지하고, 바람직하게는 물에 완전히 용해되고 저농도에서 높은 점성을 갖고 불연성 재료이면 좋다.The thickener is a white powder, which has a softening point of 650-670 ° C., preferably is completely soluble in water, has a high viscosity at low concentration and is a nonflammable material.

규사미분은 실리카 분말로 백색미분이며, 평균입도 100-5,000메쉬로 분포되어 있는 재료를 이용한 것으로, 초속경 시멘트 분말사이의 공극을 해소하면서 강도를 보강하기 위해 배합된다.Silica fine powder is a silica powder, which is a white powder, and uses a material distributed with an average particle size of 100-5,000 mesh, and is blended to reinforce strength while eliminating voids between cemented carbide powders.

이 규사미분은 실시예에서 100-150메쉬와 4000-5000메쉬로 이루어진 2종류의 규사를 배합하고 있으며, 입도가 낮은 규사는 초속경 시멘트 분말과 분말사이에 형성되는 공극에 침투하여 이들 사이의 결합력을 제공하고, 입도가 높은 규사는 증량제로 사용하기 위한 것으로, 고가의 초속경 시멘트의 배합량을 줄일 수 있다.This silica fine powder contains two types of silica sand consisting of 100-150 mesh and 4000-5000 mesh in the embodiment, and the silica particles having a low particle size penetrate into the pores formed between the cemented carbide powder and the powder and have the bonding force therebetween. In order to provide a high particle size silica sand, it is possible to reduce the amount of expensive cemented carbide cement.

수지제는 아크릴 폴리머를 이용한 수용성 분말수지를 사용한다. 이 접착제는 가수분해에 대해 매우 우수한 내성을 가지고 있고, 겉비중이 0.4-0.5l/g, pH 11.0-12.0으로 부드럽고 탄력이 있으며, 점도가 있고 0℃의 Tg를 가지고 있다.The resin is a water-soluble powdered resin using an acrylic polymer. The adhesive has very good resistance to hydrolysis, has a specific gravity of 0.4-0.5 l / g, pH 11.0-12.0, soft and elastic, viscous and has a Tg of 0 ° C.

수지제로 EVA수지, PVA수지 아크릴계 수지 등이 이용되고 있지만 EVA수지와 PVA수지는 물에 약하기 때문에 실시예에서는 방수, 강도증진, 휨강도등을 고려하여 아크릴계 수지를 사용하였다.EVA resins, PVA resins, acrylic resins, etc. are used as resins, but EVA resins and PVA resins are weak in water, and thus, acrylic resins were used in the examples in consideration of waterproofing, strength enhancement, and bending strength.

안정화제는 Zn(C17H35COO)2로 구성되어 있으며, 백색 미분말, 유리지방산(1.0% 이하), 수분(1.0%이하), 융점(120℃), 입도(325메쉬 99% 통과)의 분말상태로 초속경 시멘트에 혼합한다.Stabilizer is composed of Zn (C17H35COO) 2. It is white powder, free fatty acid (1.0% or less), water (1.0% or less), melting point (120 ℃), particle size (325 mesh 99%) Mix in light cement.

아크릴 섬유는 여러개의 단사형 압출섬유로 흡수율이 없고 비중이 0.91l/g, 화이바(Fiber)의 분포수는 850만개/m3인 것을 이용한다.Acrylic fiber is a single yarn extruded fiber with no absorption, specific gravity 0.91l / g, fiber distribution number of 8.5 million / m 3 is used.

세피오라이트는 섬유상 및 변질구조를 띤 광상조직을 갖고 있는 광물로서, 결정구는 탈크형 쇄상구조를 갖으며 그 길이는 0.1-0.8mm인 것을 이용한다. 이것은 몰드 조성물의 분말들의 결합을 강화시켜 휨강도를 보강하는데 이용된다.Sepiolite is a mineral with a fibrous and denatured mineral deposit. Crystal spheres have a talc chain structure and have a length of 0.1-0.8 mm. This is used to reinforce the bond strength of the powders of the mold composition to enhance the flexural strength.

실시태양에서는 상기한 분말상태의 혼합 조성물에 원적외선 방사제를 분말상태로 배압하여 사용할 수 있다.In an embodiment, the far-infrared radiating agent may be used as a back pressure in a powder state to the powdered mixed composition.

원적외선 방사제는 원적외선을 방사하는 원료인 맥반석을 주제로 하며, 실시예에 적용되는 맥반석은 소성로에 넣고 750-800℃의 고온분위기로 가열한 것을 이용하며, 이러한 맥반석은 천연 맥반석보다 더 많은 량의 원적외선을 방사할 수 있다.Far-infrared radiating agent is based on elvan, which is a raw material that emits far-infrared rays. The elvan is applied to the kiln in a firing furnace and heated to a high temperature of 750-800 ° C., which is higher than natural elvan. Far infrared rays can be emitted.

원적외선 방사재는 맥반석 대신 황토, 게르마늄, 옥 등 일반적으로 잘 알려진 원적외선 방사물질중 적어도 하나 또는 그 이상을 선택하여 치환하거나 또는 개시제로부터 맥반석을 혼합할 수 도 있다.Far-infrared radiating material may be substituted by at least one or more of the well-known far-infrared radiating material such as ocher, germanium, jade instead of elvan, or mixed with elvan.

이러한 배합물 이외에 탈취재나 항균제를 더 포함하여 배합할 수 있으며, 탈취재는 세라믹 자체에 Mn2O3, Fe2O3, TiO3등의 금속촉매와 다공성이며 흡착성분이 강한 원료를 사용하는 것이 좋으며, 산화, 환원반응이 원활하게 이루어지게 하므로서 악취를 중화시키게 된다.In addition to these formulations, it can be blended with an additional deodorant or antibacterial agent. For the deodorant, it is recommended to use a metal catalyst such as Mn 2 O 3 , Fe 2 O 3 , TiO 3 , and a porous and strong adsorbent. By oxidizing, reducing and reducing the odor is neutralized.

항균제(1-3%)는 무기계 항균제인 금속이온을 함유한 유리분말과 활성산온에 의한 오존파괴(살균) 유기항균제를 결합하여 지속적으로 항균을 99.9이상 유지할 수 있도록 한다.Antibacterial agent (1-3%) combines glass powder containing metal ion, which is an inorganic antibacterial agent, with ozone depletion (sterilization) organic antibacterial agent by active acid temperature, so that antibacterial agent can be continuously maintained over 99.9.

본 발명의 실시예에 의한 몰딩재는 분말상태로서 운반 및 보관의 편리성을 강조한다. 분말상태의 몰딩재는 물과 혼합하여 몰드폼에 발포하거나 또는 주입하는 것에 의해 다양한 형태의 건축물 내외벽의 구조물을 성형할 수 있다.The molding material according to an embodiment of the present invention emphasizes the convenience of transportation and storage in a powder state. The powdered molding material may be molded into various forms by foaming or injecting into a mold foam to form structures of the inner and outer walls of the building.

통상의 내장 기재에 본 발명의 건축 구조물 성형을 위한 몰딩재를 조성하기 위한 구체적인 실시예는 이하의 설명으로부터 명확해질 수 있다.Specific embodiments for forming a molding material for forming a building structure of the present invention on a conventional embedded substrate may be apparent from the following description.

(실시예 1)(Example 1)

초속경 시멘트 분말을 주제로 하는 몰딩재를 다음과 같이 제조한다. 실시예에 의한 몰딩재는 중량%로 초속경 시멘트 40-60%, 증점제 0.3-0.5%, 규사 30-45%, 수지제 5-7%, 안정화제 1-3%, 섬유 0.3-0.5%, 세피오라이트 2-4%, 원적외선 방사재 15-20%를 적절히 배열하였다.A molding material based on cemented carbide cement powder is prepared as follows. Molding material according to the embodiment by weight% cemented carbide 40-60%, thickener 0.3-0.5%, silica sand 30-45%, resin 5-7%, stabilizer 1-3%, fiber 0.3-0.5%, sepiolite 2-4% and 15-20% of the far infrared radiator were properly arranged.

주재료인 초속경 시멘트의 중량을 40% 이하로 배합될 경우에는 부착강도가 저하되어 균열현상이 일어날 수 있고, 60% 이상일 경우에는 부착강도는 우수하나 다른 배합물과의 배합비를 조절하기 어렵기 때문에 바람직하게는 50%를 기준으로 하여 나머지 배합물을 배합하는 것이 좋다.When the weight of the cemented carbide cement is less than 40%, the adhesion strength decreases and cracking may occur.In the case of 60% or more, the adhesion strength is excellent but it is difficult to control the mixing ratio with other compounds. For example, it is better to combine the remaining formulations based on 50%.

규사의 중량을 30% 이하로 배합할 경우에는 시멘트의 배합비가 높아져 가격면에서 불리하고, 반대로 45%이상 배합할 경우에는 시멘트의 배합비가 감소되어 강도면에서 불리하므로, 바람직하게는 37%정도가 적당하다.When the weight of silica sand is blended at 30% or less, the compounding ratio of cement is high, which is disadvantageous in terms of price. On the contrary, when blending more than 45%, the blending ratio of cement is decreased, which is disadvantageous in terms of strength. It is suitable.

수지제는 그 배합비를 5%이하로 배합할 경우 결합강도 및 휨강도가 약해지고, 반대로 7%이상으로 배합할 경우에는 결합강도와 휨강도면에서 경직현상이 일어날 수 있기 때문에 바람직하게는 6%의 배합비가 적당하다.When the resin is blended at a blending ratio of 5% or less, the bond strength and flexural strength become weak. On the contrary, when blended at 7% or more, a rigidity may occur in terms of bond strength and flexural strength. It is suitable.

원적외선 방사제는 전체 배합량에서 15% 이하일 경우에는 원적외선 방사량이 줄어들고, 반대로 2% 이상일 경우에는 원적외선 방사량은 증가할 수 있으나 다른 배합물과 배합비를 조절하기 힘들다. 따라서 전체 중량에서 2%정도를 배합하는것이 좋다.Far infrared ray radiant is less than 15% of the total amount of the far infrared radiation is reduced, on the contrary 2% or more far infrared radiation dose may increase, but it is difficult to control the mixing ratio with other formulations. Therefore, it is good to mix 2% of the total weight.

본 발명은 초속경 시멘트 500g, 증점제 4g, 규사 378g, 수지제 60g, 안정화제 20g, 섬유 4g, 세피오라이트 30g을 혼합하고, 나머지를 원적외선 방사 4g을 투입하여 혼합기에서 배합한 후 물과 혼합하여 35-45℃의 건조기 안에서 24시간 이상 건조한 후 데시케이터 안에서 24시간 방치한 후 표면시험을 하였다.In the present invention, 500 g of cemented carbide, thickener 4 g, silica sand 378 g, resin 60 g, stabilizer 20 g, fiber 4 g, and sepiolite 30 g are mixed. After drying for more than 24 hours in a dryer of 45 ℃ left for 24 hours in a desiccator and the surface test.

표1을 참조하면, 본원인은 한국소방 검정공사에 의뢰하여 시험체에 대한 표면시험을 테스트하였으며, 테스트 조건은 표준관을 이용하여 표준배기온도곡선을 작성하였고, 가열시험은 표준을 사용하여 예비가열을 한 후, 후면 뚜껑을 제거하고 배기온도를 측정하는 열전대의 눈금이 약 50℃로 강하한 후 실시하였다. 또한 연기를 투과하는 광량은 가열시험하면서 15초이내 마다 측정하였고, 표준온도곡선을 넘는 온도시간면적을 계산하였으며, 단위면적당 발연계수(CA)를 기록하였다.Referring to Table 1, the applicant tested the surface test on the test specimen by requesting the Korea Fire Protection Corporation, and the test condition was prepared by using a standard tube to create a standard exhaust temperature curve, and the heating test was preheated using a standard. After removing the back cover, the thermocouple for measuring the exhaust temperature was dropped after dropping to about 50 ° C. In addition, the amount of light passing through the smoke was measured every 15 seconds during the heating test, the temperature time area over the standard temperature curve was calculated, and the coefficient of smoke per unit area (CA) was recorded.

시험규정은 KS F 2271(건축물의 내장 재료 및 구조의 난연성 시험방법)의 규정에 의한 난연 2급 시험중 표면시험을 한 것이다.The test regulation is the surface test during the flame retardant class 2 test in accordance with KS F 2271 (Test method for flame retardancy of building materials and structures).

상기한 시험결과들은 본 발명을 예시하고자 제공된 것으로, 본 발명은 초속경 시멘트에 다른 배합성분들을 다양한 비율로 조합할 수 있다. 상기 몰드 조성물은 물과 혼합하여 액상 상태로 다양한 형태의 몰드폼에 주입하여 양생한 후 몰드폼을 탈형시킴으로써 실현이 가능하며, 조성물의 범위는 특허청구범위에 의해 규정된다.The test results described above are provided to illustrate the present invention, and the present invention may combine different compounding ingredients in various ratios in cemented carbide. The mold composition can be realized by mixing with water and injecting the mold foam in various forms in a liquid state and curing the mold foam, and the scope of the composition is defined by the claims.
