It is prepared by adding water to the mixture composed of weight percent, mixing, curing and pressing.
본 발명의 고강도 바닥 패널은 압축강도와 굽힘 강도가 일반 시멘트 제품과 비교하여 약 3배 이상 증가되며 단열, 내열, 흡음, 차음, 충격 및 진동흡수 능력이 우수하여 사무실, 실험실, 전산실 등의 이중 바닥용 패널로 또는 주택, 식당, 아파트 등의 조립식 온수 난방용 바닥 패널로 활용이 기대된다.The high strength floor panel of the present invention has an increase in compressive strength and bending strength by about 3 times or more compared with general cement products, and has excellent insulation, heat resistance, sound absorption, sound insulation, shock and vibration absorption, and double floors in offices, laboratories, computer rooms, etc. It is expected to be used as a panel for prefabricated hot water heating in houses, restaurants and apartments.
Description
본 발명은 건물의 바닥 패널로 적합한 기계적 강도(압축, 굽힘, 충격 강도 등), 단열성, 내열성, 차음성 등이 우수한 고강도 바닥 패널의 조성 및 그 제조방법에 관한 것이다. The present invention relates to a composition of a high-strength floor panel having excellent mechanical strength (compression, bending, impact strength, etc.), heat insulation, heat resistance, sound insulation, and the like, which is suitable as a floor panel of a building, and a method of manufacturing the same.
최근 빌딩사무실, 실험실 또는 전산실 등의 바닥은 뜬 바닥 구조를 이루는 액세스 플로어를 채택하고 있으며 여기에 사용되는 재료는 금속(철, 알루미늄), 목재, 콘크리트 등이 사용되고 있다. 한편 점차 고층화되는 아파트 등의 건축물의 바닥은 층간 소음이나 충격·진동 등의 규제 강화로 현재의 경량기포시멘트 시공 방법으로는 만족 할 만한 결과를 얻지 못하고 있는 실정으로 점차 상기한 이중 바닥 패널과 같은 뜬 바닥 구조를 채택하여 흡·차음, 충격·진동을 흡수하고 시공의 편리성, 시공기간의 단축, 각종 파이프 배관 등의 처리문제를 동시에 해결 할 수 있는 방안이 절실히 요구되어왔다. 그러나 현재 이중 바닥 패널용 재들은 상대적으로 고가이며 금속 제품 등은 부식 등의 문제점을 가지고 있어 특히 바닥 온수 난방을 요구하는 시스템에서는 활용이 불가능하다. 이를 해결하기 위하여 여러 가지 방법이 알려지고 있는데, 예로서 일본공개특허공보 제2001-89206호(2001. 04. 03)에는 포틀랜트 시멘트, 알루미나 시멘트, 플라이 애쉬, 목분, 조강성분으로 석고, 탄산칼슘, 소석회, 규조토 등의 규산질 재료와 아크릴, 우레탄, 아크릴우레탄 등의 수지를 첨가한 패널의 제조방법을 기술하고 있다. 또한, 일본공개특허공보 제2001-213652호(2001. 08. 07)에는 포틀랜트 시멘트, 고로 슬라그, 플라이 애쉬, 화산재 등의 시멘트에 아라미드, 폴리에틸렌 등의 유기섬유를 가하고 염화칼슘, 황산칼슘 등의 무기염을 첨가한 패널의 제조방법이 소개되고 있다. 상기 공지자료에서는 여러 가지 시멘트와 첨가물을 사용하므로 생산공정이 복잡하고 다단계이어서 산업화가 곤란하고 또한 바닥재로서 소기의 목적을 달성하기가 어렵다고 생각된다. Recently, the floors of building offices, laboratories, or computer rooms adopt an access floor that has a floating floor structure. The materials used here include metals (iron, aluminum), wood, and concrete. On the other hand, the floors of buildings, such as apartments, which are gradually getting higher, are not getting satisfactory results with the current method of constructing lightweight foam cement due to the tightening of noise, shock, and vibration between floors. By adopting the floor structure, there is an urgent need for a method to absorb sound absorption, sound insulation, shock and vibration, and to simultaneously solve problems such as convenience of construction, shortening of construction period, and various pipe piping. However, current double floor panel ashes are relatively expensive, and metal products have problems such as corrosion, and thus cannot be utilized in systems requiring floor heating. In order to solve this problem, various methods are known. For example, Japanese Patent Laid-Open No. 2001-89206 (2001. 04. 03) discloses portland cement, alumina cement, fly ash, wood powder, gypsum and calcium carbonate as crude components. And a siliceous material such as calcined lime and diatomaceous earth and a resin such as acrylic, urethane, and acrylic urethane are described. In addition, Japanese Laid-Open Patent Publication No. 2001-213652 (August 07, 2001) added organic fibers such as aramid and polyethylene to cement of portland cement, blast furnace slag, fly ash, volcanic ash, and the like, such as calcium chloride and calcium sulfate. The manufacturing method of the panel which added the inorganic salt is introduced. In the above publication, since various cements and additives are used, the production process is complicated and multi-stage, which makes it difficult to industrialize and to achieve the intended purpose as a flooring material.
따라서 사무실, 실험실 또는 대형 전산실, 주택, 아파트 등의 바닥 재와 바닥 온수 난방 시스템에 적용이 가능하고 고하중에 견디며 일반 콘크리트 패널과 비교하여 비중이 적고 단열, 내열, 흡·차음, 및 충격·진동 흡수 기능 등이 우수하면서 동시에 가격이 저렴한 새로운 재료의 개발이 절실히 요구되고 있다. Therefore, it can be applied to flooring and hot water heating systems in offices, laboratories or large computer rooms, houses, apartments, etc., withstands high loads, has a low specific gravity compared to general concrete panels, and absorbs heat, heat, sound absorption and sound insulation, and shock and vibration. There is an urgent need for the development of new materials with superior functionality and low cost.
본 발명은 현재 사용되고 있는 각종 이중 바닥 패널용 패널뿐만 아니라 온수 난방용 바닥 패널로도 사용이 가능한 가격이 저렴하고 생산성이 높고 제조공정이 단순하며 상기한 여러 가지 특성을 갖춘 고강도 바닥 패널 조성물과 그 제조방법을 개발하고자 한 것이다. The present invention provides a high-strength floor panel composition having a variety of the above characteristics and a low cost, high productivity, simple manufacturing process, which can be used as not only the various double floor panel panels currently used, but also hot water heating floor panels. It is intended to develop.
본 발명의 고강도 바닥 패널은 단독주택, 아파트, 사무실 및 공공시설 등의 바닥 재로 사용 할 경우 중량물의 적재하중을 견딜 수 있을 뿐만 아니라 무기질계 재료의 여러 가지 장점인 단열, 내열, 흡·차음, 충격·진동 흡수 및 높은 내구성을 가지고 있어 반영구적인 수명을 가질 수 있을 것으로 기대된다. The high-strength floor panel of the present invention can withstand heavy loads when used as flooring in single-family homes, apartments, offices, and public facilities, as well as insulation, heat resistance, sound absorption, sound insulation, and impact that are various advantages of inorganic materials. It is expected to have semi-permanent lifespan with vibration absorption and high durability.
따라서 본 발명의 기술적 과제는 상기한 여러 가지 특성을 가진 제품을 생산하기 위한 조건으로서 압축강도가 약 150∼200㎏/㎠, 굽힘강도가 약 80∼100㎏/㎠ 이며 겉보기 비중이 약 1.1∼1.5인 단열, 내열, 흡·차음, 충격·진동 흡수 및 내구성이 우수한 패널의 조성과 그 제조방법을 제시하고자 한다. 본 발명의 구성 및 특성은 주성분이 고강도 시멘트 조성물이고 이를 저 알칼리성으로 제조하여 첨가물의 열화현상을 방지하고 나무 칩을 첨가하여 굽힘 강도 등을 증진시킨 것이다. Therefore, the technical problem of the present invention is a condition for producing a product having various characteristics described above, the compressive strength is about 150 ~ 200㎏ / ㎠, the bending strength is about 80 ~ 100㎏ / ㎠ and the apparent specific gravity is about 1.1 ~ 1.5 The present invention proposes a composition of a panel excellent in phosphor insulation, heat resistance, sound absorption and sound insulation, shock and vibration absorption, and durability. The composition and characteristics of the present invention is that the main component is a high-strength cement composition, which is prepared with low alkalinity to prevent deterioration of additives, and to improve bending strength by adding wood chips.
본 발명의 고강도 바닥 패널은 제조방법에 따라 그 조성의 구성성분을 달리한다. 즉 자연양생법에 의한 제조방법과 프레스 공법에 의한 제조방법으로 구분하여 그 구성 및 작용에 대해 설명하고자 한다. High-strength floor panels of the present invention vary the composition of the composition according to the manufacturing method. In other words, it will be divided into the manufacturing method by the natural curing method and the manufacturing method by the press method to explain the configuration and operation.

Here, the high-strength, fast-hard cement is calcium aluminate (3CaO 5Al 2 O 3 ), tricalcium silicate (3CaOSiO 2 ), calcium sulfoaluminate (4CaO 3Al 2 ), as shown in the X-ray diffraction analysis of FIG. 1. O 3 · SO 3 ), calcium, iron, and magnesium silicate ((Ca, Fe, Mg) SiO 3 )), and the composition ratio of calcium aluminate (3CaO5Al 2 O 3 ) is about 40-50 %, Tricalcium silicate (3CaOSiO 2 ) about 30 to 40%, calcium sulfoaluminate (4CaO 3Al 2 O 3 SO 3 ) and calcium iron magnesium silicate (CaFeFe) 3 )) is about 5-10% and the brain powder degree is about 4200cm 2 / g. Table 1 shows the chemical composition of high strength and fast hard cement.
[표 1] 고강도·속경성 시멘트의 화학성분[Table 1] Chemical Composition of High Strength and Hard Cement
나무 칩은 목재를 파쇄하여 사용하거나 목재공장에서 발생되는 폐 목재로 길이가 약 0.1∼2㎝, 폭이 약 0.5∼2.0㎜로 분쇄된 것이며 모래는 평균직경이 약 200㎛이하이고 실리카는 흄드 실리카, 콜로이드 실리카 등의 어떠한 실리카를 사용하여도 좋으나 입자 크기가 약 10㎛이하이어야 한다. Wood chips are used as crushed wood or waste wood produced in a wood mill, and ground to about 0.1 to 2 cm in length and 0.5 to 2.0 mm in width. Sand has an average diameter of less than about 200 µm and silica is fumed silica. Any silica, such as colloidal silica, may be used, but the particle size should be about 10 μm or less.
상기한 본 발명의 고강도 바닥 패널의 정량적인 조성에 있어서, 고강도·속경성 시멘트의 구성비가 30중량%이하에서는 제품의 강도가 저하될 뿐만 아니라 나무 칩 첨가량의 증가로 내열성을 감소시킬 수 있으며 50중량% 이상에서는 제품의 강도는 증가하나 비중이 증가하여 경량성이 감소하는 단점이 있다. 그러나 내열성은 증가하여 220°C이상의 온도에서도 안정한 상태를 유지한다. 나무 칩의 사용량은 5중량% 이하에서는 제품의 비중이 증가되고 10중량% 이상에서는 비중은 감소하나 강도 및 내열성 등이 저하되는 결점이 발생한다. In the quantitative composition of the high-strength floor panel of the present invention, when the composition ratio of the high-strength fast cement is less than 30% by weight, not only the product strength is lowered, but also the heat resistance can be reduced by increasing the amount of wood chips added, and the weight is 50%. More than%, the strength of the product increases, but the weight is reduced due to the increased specific gravity. However, the heat resistance is increased to maintain a stable state even at temperatures above 220 ° C. The use of wood chips increases the specific gravity of the product below 5% by weight and decreases the specific gravity above 10% by weight, but the strength and heat resistance decrease.
한편 상기한 조성물로 구성된 본 발명의 고강도 바닥 패널을 제조하기 위해서는 상기한 혼합물에 물/시멘트비를 0.5∼0.6되게 물을 첨가하여 믹싱 챔버에서 잘 혼합하여 몰탈을 제조한다. 이 몰탈을 일정 크기의 판상 형틀에 투입하여 진동·압축하여 약 50∼70°C, 상대습도 90%인 양생실에서 건조시켜 자연양생 한다. 대량생산을 위해서는 대형 장방형 틀에 몰탈을 투입하고 양생시킨 후 적당한 크기로 절단하여 제품을 제조한다. On the other hand, in order to manufacture the high-strength floor panel of the present invention composed of the above composition, water is added to the mixture at a water / cement ratio of 0.5 to 0.6, and mixed well in a mixing chamber to prepare mortar. The mortar is put into a plate-shaped mold of a certain size, vibrated and compressed, dried in a curing room having a temperature of about 50 to 70 ° C. and a relative humidity of 90%, and cured naturally. For mass production, the mortar is put into a large rectangular mold, cured, and then cut to a suitable size to manufacture a product.
압축강도, 굽힘강도, 충격강도, 흡수율, 비중, 및 내열성 등은 KS L 5103(길모드 침에 의한 시멘트의 응결시간 시험), KS L 5105(수경성 시멘트 몰탈의 압축강도 시험)규격에 의해 시험한 결과이다.

The result is.
아래 실시 예1은 본 발명의 고강도 바닥 패널을 자연양생법으로 제조할 때에 구체적인 조성과 제조방법에 관한 것으로 이를 실시 예와 함께 설명하고자 한다.Example 1 below relates to a specific composition and manufacturing method when manufacturing the high-strength floor panel of the present invention by the natural curing method will be described with this embodiment.
(2) 프레스 공법에 의한 본 발명의 고강도 바닥 패널의 제조(2) Production of high strength floor panel of the present invention by the press method
본 방법에 의한 고강도 바닥 패널의 조성은 고강도·속경성 시멘트 약 40∼80중량%와 나무 칩 약 10∼30중량%, 실리카는 흄드 실리카, 콜로이드 실리카 등의 어떠한 실리카를 사용하여도 좋으나 약 3∼10중량% 및 바인더 역할을 하는 알루미늄 포스페이트 약 1∼3중량%로 구성된다. 상기한 조성물 중 고강도·속경성 시멘트 및 나무 칩은 상기한 자연양생법에서 사용한 재료와 동일한 것이고 황산 알루미늄콜로이드 실리카 및 알루미늄 포스페이트는 일반 공업규격품이다. 자연양생법에 의한 본 발명의 고강도 바닥 패널의 제조와 마찬가지로 고강도·속경성 시멘트의 구성비가 40중량%이하에서는 제품의 강도가 저하될 뿐만 아니라 나무 칩 첨가량의 증가로 내열성을 감소시킬 수 있으며 80중량% 이상에서는 제품의 강도는 증가하나 비중이 증가하여 경량성이 감소하는 단점이 있다. 그러나 내열성은 증가하여 700°C이상의 고온에서도 안정한 상태를 유지한다. 나무 칩의 사용량은 10중량% 이하에서는 제품의 비중이 증가되고 30중량% 이상에서는 비중은 감소하나 강도 및 내열성 등이 저하되는 결점이 발생한다.The composition of the high-strength floor panel according to the present method is about 40 to 80% by weight of high-strength cement and about 10 to 30% by weight of wood chips, and silica may be any silica such as fumed silica or colloidal silica. 10 weight percent and about 1-3 weight percent aluminum phosphate acting as a binder. The high strength and fast hardening cement and wood chips in the above composition are the same as those used in the above natural curing method, and aluminum sulfate colloidal silica and aluminum phosphate are general industrial standards. As in the manufacture of the high strength floor panel of the present invention by the natural curing method, when the composition ratio of the high strength and fast curing cement is 40% by weight or less, the strength of the product is not only lowered, but the heat resistance can be reduced by increasing the amount of wood chips added, and 80% by weight. In the above, the strength of the product is increased, but the specific gravity is increased, there is a disadvantage in reducing the light weight. However, the heat resistance is increased to maintain a stable state even at high temperatures over 700 ° C. The use of wood chips increases the specific gravity of the product below 10% by weight and decreases the specific gravity above 30% by weight but results in a decrease in strength and heat resistance.
본 발명의 고강도 바닥 패널의 제조방법은 상기한 조성물을 혼합하여 물/시멘트비가 약 0.4∼0.5되게 물을 첨가하여 혼합한 후 가압 성형하여 판상의 성형체를 제조한다. 가압조건은 면압이 약 700톤/㎡으로 프레스 하여 50∼70°C에서 양생시킨다.In the method for producing a high-strength floor panel of the present invention, the above composition is mixed to add water so that the water / cement ratio is about 0.4 to 0.5, and then mixed under pressure to produce a plate-shaped molded body. Pressurization conditions are cured at 50 ~ 70 ° C by pressing a surface pressure of about 700 tons / ㎡.

상기한 본 발명의 두 가지공법에 의한 본 발명의 고강도 바닥 패널의 제조방법을 비교하여 보면 프레스 공법이 자연양생법에 비해 기계적 강도 등의 물리적 특성이 우수하고 비중이 적어 단위 면적 당 무게 역시 가볍다. 그리고 제품의 외관도 자연양생에 비해 미려하며 기포 등의 결함이 거의 나타나지 않아 초기 시설 투자비가 다소 소요되나 효율적인 방법으로 사료된다. 그러나 수요량이나 용도 및 경제성 등의 관점에서 자연 양생법에 의한 제조방법도 고려 할 수 있을 것이다.Comparing the manufacturing method of the high-strength floor panel of the present invention by the two methods of the present invention described above, the press method is superior in physical properties such as mechanical strength and less specific gravity than the natural curing method, the weight per unit area is also light. In addition, the appearance of the product is more beautiful than natural curing, and since there are almost no defects such as bubbles, the initial facility investment cost is somewhat, but it is considered to be an efficient method. However, the manufacturing method by natural curing method may be considered in terms of demand quantity, use and economical efficiency.
본 발명의 고강도 바닥 패널은 공지의 일반 시멘트를 이용한 패널과 비교하여 볼 때 압축강도, 굽힘 강도 등의 물리적 특성이 약 3배 이상 증가하므로 사무실, 실험실, 전산실 등의 이중 바닥 패널용으로 활용 할 수 있을 뿐만 아니라 주택 및 아파트 등의 조립식 온수 난방용 바닥 패널로 활용될 것으로 기대된다.High-strength floor panels of the present invention can be utilized for double floor panels, such as offices, laboratories, computer rooms, because the physical properties such as compressive strength, bending strength, etc. increases more than three times compared to the panel using a known general cement In addition, it is expected to be used as a prefabricated hot water floor panel for houses and apartments.
