Description

조립식 패널 구조체용 폴리에스테르 난연심재 및 그 제조방법 {Polyester fire-retardant core matrix for prefabricating panel and Process of producing thereof}Polyester fire-retardant core matrix for prefabricating panel and process of producing etc

본 발명은 산업 및 상업용 건축물에 적용되는 조립식패널(샌드위치 패널) 구조체 내부에 사용되는 폴리에스테르 섬유를 주원료로 하는 난연심재 및 그 제조방법에 관한 것이다.The present invention relates to a flame retardant core material mainly comprising polyester fibers used in prefabricated panel (sandwich panel) structures applied to industrial and commercial buildings, and a method of manufacturing the same.

일반적으로 조립식 패널은 약 0.5mm정도의 강판사이에서 흡음성이나 단열성이 있는 심재를 넣어 접착시켜서 제조되는데, 사용되는 심재는 구조적인 지지성능이 필요하므로 일정수준이상의 압축강도를 필요로 한다. 지금까지 주로 사용되는 심재는 폴리우레탄폼, 스치로폼과 같은 유기질재료와 유리면, 암면과 같은 무기질재료가 사용되어 왔으나, 유기질폼 재료의 경우 압축강도의 발현에는 장점이 있으나 연소특성으로 인하여 화재발생시 내연성이 취약하다는 단점때문에 점차 활용성이 떨어지고 있다.반면에 무기질재료는 난연성능은 우수하나 제조공정상의 분진발생 및 인체유해성으로 인하여 작업자나 시공자들이 기피하고 있는 실정이다.In general, prefabricated panels are manufactured by attaching a sound absorbing or insulating core material between steel plates of about 0.5mm, and the core material used requires a certain level of compressive strength since structural support performance is required. The core materials used up to now have been organic materials such as polyurethane foam and styrofoam and inorganic materials such as glass wool and rock wool, but organic foam materials have advantages in the development of compressive strength, but due to combustion characteristics Due to its weakness, its utilization is gradually decreasing. On the other hand, inorganic materials have excellent flame retardant performance, but are avoided by workers or contractors due to dust generation and human harmfulness in the manufacturing process.

최근건축자재로 많이 사용되고 있는 폴리에스테르 흡음단열재는 타 유기질재료와는 달리 연소시에 유해가스가 발생하지 않고, 유리면이나 암면과 같은 무기섬유질 재료에 비해 시공상의 용이성이나 인체무해성, 환경변화에 따른 형태변형이 없는 반영구적인 수명때문에 각광받고 있으나 난연성능의 미흡으로 인해 용도확대에 많은 장애가 있었다. 시중에 판매되고 있는 난연도료나 내화도료를 이용하여 폴리에스테르 견면에 표면 난연성능을 부여하는 제품도 있었으나 25mm이하의 두께,150Kg/㎥이상의 고밀도의 판재로밖에 제조할 수 없어 저밀도, 고두께(70Kg/㎥이하, 50mm이상)를 필요로 하는 조립식 패널 구조체의 심재로 사용할 수 없는 문제점이 있었다.Unlike other organic materials, polyester sound-absorbing insulation materials, which are widely used as building materials in recent years, do not generate harmful gases during combustion, and are easier to construct, harmless to humans, and environmental changes than inorganic fiber materials such as glass wool or rock wool. Although it has been spotlighted for its semi-permanent life without shape deformation, there have been many obstacles in expanding its use due to the lack of flame retardant performance. Some products use commercially available flame retardant paints or fire-resistant paints to impart surface flame retardant performance to polyester backings.However, they can only be manufactured from plates with a thickness of 25 mm or less and high density of 150 Kg / m3 or higher, resulting in low density and high thickness (70Kg / M 3 or less, 50 mm or more) there was a problem that can not be used as a core material of the prefabricated panel structure.

따라서 본 발명은 상기한 바와 같은 선행기술의 제반 문제점을 해소할 수 있는 조립식 패널 구조체용 폴리에스테르 난연심재를 제조하는 것을 기술적 과제로 한다.Therefore, a technical object of the present invention is to manufacture a polyester flame retardant core material for a prefabricated panel structure which can solve all the problems of the prior art as described above.

상기한 과제를 해결하기 위하여 본 발명자는 저밀도 고두께의 폴리에스테르 견면에 대한 균일한 난연제처리공정, 건조공정 및 압축강도, 내구성의 향상을 위한 난연심재의 발포공정을 통해 난연성능이 우수하고 높은 강도와 낮은 흡수율을 갖는 조립식 패널의 내부심재를 제조할 수 있다는 것을 알게 되어 본 발명을 완성하게 된 것이다.In order to solve the above problems, the present inventors have excellent flame retardant performance and high strength through a uniform flame retardant treatment process for a high density polyester cotton, a drying process and a foaming process of a flame retardant core for improving durability The present invention has been completed by knowing that the inner core material of a prefabricated panel having a low water absorption rate can be manufactured.

Provided is a method for preparing.

또한 본 발명에서는 밀도70Kg/㎥이하, 두께 50mm이상인 조립식 패널 구조체용 폴리에스테르 난연심재를 얻을 수 있다.Further, in the present invention, a polyester flame retardant core material for a prefabricated panel structure having a density of 70 Kg / m 3 or less and a thickness of 50 mm or more can be obtained.

이하 본 발명을 보다 상세히 설명하기로 한다.Hereinafter, the present invention will be described in more detail.

본 발명의 조립식 패널 구조체용 폴리에스테르 난연심재는 먼저 주재료인 저밀도의 폴리에스테르 견면(2)을 상하로 설치된 노즐식 스프레이를 구비하는 작업대에 공급하고, 스프레이의 상하노즐로 난연제액(1)을 분사하여 상기 견면의 내부까지 난연제액을 침투시키는 것이 바람직하다. 상기 난연제액의 침투공정은 전술한 스프레이방식외에도 디핑방법이나 롤러방식을 사용할 수도 있다. 상기 난연제액은 주성분인 소디윰실리케이트를 70% 이상 함유하고, 제일인산나트륨, 수산화마그네슘, 인산에스테르계화합물, 산화알루미늄, 수산화알루미늄, 산화안티몬, 몰리브덴산염 및 주석산아연으로 구성된 난연첨가제군에서 선택된 1종 이상의 난연첨가제가 추가적으로 함유되어 있으며, 농도가 30∼70%인 것이 바람직하다. 난연제액 농도가 30%미만인 경우에는 견면의 내부까지 난연제액의 침투는 용이하나, 후공정에서 건조부하가 과도한 단점이 있고, 70%를 초과한 경우에는 후공정에서 건조부하는 감소하나 견면의 내부까지 난연제액의 침투 및 균일한 처리가 어려운 단점이 있다.The polyester flame retardant core material for a prefabricated panel structure of the present invention first supplies a low density polyester shoulder face (2) as a main material to a work bench having nozzle sprays installed up and down, and sprays the flame retardant liquid (1) with the upper and lower nozzles of the spray. It is preferable to penetrate the flame retardant solution to the inside of the shoulder. In addition to the above-described spray method, the flame retardant infiltration step may use a dipping method or a roller method. The flame retardant solution contains more than 70% of the main component sodium silicate, selected from the group of flame retardant additives consisting of sodium phosphate, magnesium hydroxide, phosphate ester compound, aluminum oxide, aluminum hydroxide, antimony oxide, molybdate and zinc stannate. More than one flame retardant additive is further contained, and the concentration is preferably 30 to 70%. If the flame retardant solution concentration is less than 30%, the flame retardant solution is easily penetrated to the inside of the plush, but there is a disadvantage in that the dry load is excessive in the post process. Until the penetration of flame retardant solution and uniform treatment is difficult.

상기 공정에서 견면에 난연제액을 균일하게 침투시킨 다음, 롤러(3)로 상기 견면을 압축하여 견면내부에까지 난연제액이 침투하도록 하고 견면의 밀도를 높이는데 상기 액분사 및 롤러압축공정은 2회이상 반복하는 것이 보다 양호하게 난연제액을 흡수시키는 방법이 된다. 상기와 같이 견면을 롤러압축하면 후에 반복되는 액분사시에 난연제액이 보다 용이하게 견면에 흡수될 수 있다. 또한 최종 롤러압축으로 견면에 흡수된 잉여난연제액의 일부를 제거함으로써 후공정인 공기흡배기를 이용한 건조공정의 부하를 줄일 수 있다.In the process, the flame retardant liquid is uniformly infiltrated into the cotton wool, and then the roller is compressed with the roller 3 to allow the flame retardant liquid to penetrate into the inner surface of the cotton and increase the density of the cotton. The liquid spraying and roller compression process is repeated two or more times. It becomes a method of absorbing a flame retardant liquid more favorably. When the roller is compressed as described above, the flame retardant liquid may be more easily absorbed into the shoulder during repeated liquid spraying. In addition, by removing some of the excess flame retardant liquid absorbed on the shoulder surface by the final roller compression can reduce the load of the drying process using the air intake and exhaust process.

본 발명에서는 상기 압축공정이 끝난 견면을 후공정으로 공급하게 되는데, 먼저 1쌍 이상의 타공롤러(4)사이에 견면을 공급하여 공기흡입기능이 있고 흡인력조절이 가능한 타공롤러를 통해 견면의 상하부에서 난연제액을 빨아내게 된다. 상기 1쌍이상의 타공롤러는 건조공정의 효율성을 향상시키기 위해 2셋트이상으로 구성하는 것이 바람직하다. 최종의 타공롤러단에서는 난연심재의 두께확보를 위해 흡인력제거시 난연심재의 복원력을 감안하여 공급되는 견면보다 큰 치수로 흡인하며, 제품초기 진입시의 원활한 흡인작용을 위해 제품인식 센서와 상부롤러의 자동위치 선정 시스템을 활용하고 상하 롤러사이의 간격을 후단으로 갈수록 넓게 하는 것이 바람직하다. 그 이유는 전단의 롤러에서는 흡입성능을 잘 발현할 수 있도록 하고, 후단의 롤러에서는 난연심재의 두께확보가 잘 발현될 수 있도록 하기 위한 것이다.In the present invention, the compression process is supplied to the end of the plush process, first supply the plush between one or more perforated rollers (4) through the air suction function and the suction force control through the perforated rollers flame retardant in the upper and lower parts The liquid is sucked out. The one or more pair of perforated rollers is preferably composed of two or more sets in order to improve the efficiency of the drying process. In the final perforated roller stage, in order to secure the thickness of the flame retardant core, the suction is removed to the size larger than the supplied surface in consideration of the resilience of the flame retardant core when removing the suction force, and the product recognition sensor and the upper roller are automatically It is desirable to utilize a positioning system and widen the gap between the upper and lower rollers toward the rear end. The reason is to make it possible to express the suction performance in the roller of the front end, and to secure the thickness of the flame retardant core material in the roller of the rear end.

상기 액제거과정이 끝난 후, 견면을 건조룸에 공급하여 마이크로웨이브발생기로(5) 2.47GHz대의 마이크로웨이브를 조사하여 견면의 내부로부터 난연제액을 증발, 건조시킨다. 본 건조공정에서는 상기 난연제액이 건조될 때 접착제역할을 하므로 건조시키기 전에 공급벨트(6)와 분리시켜 견면과 벨트의 접착을 방지하는 것이 바람직하다. 또한 마이크로웨이브의 주파수대역에 있어서는 수분건조를 위하여 사용되는 물분자의 진동에 가장 적합한 것으로 알려진 2.47GHz대의 주파수 대역을 사용하였다. 마이크로웨이브의 설치구간을 통과한 예열된 공기를 에어블로잉 장치와 에어셕션장치를 통하여 견면의 하부에서 불어 건조중의 견면내부에 잔류하고 있는 수증기를 불어내고, 견면의 상부에서는 하부로부터 불어진 공기와 견면으로부터 증발된 수증기를 흡입하여 외부로 유출시킴으로써 건조효율을 증대시킬 수 있다. 상기 벨트는 콘베이어 하부에 설치된 세척유니트를 통과하면서 부착된 이물질이 제거된다. 본 발명에서는 상기 건조공정을 3회이상 반복하여 견면을 완전히 건조시킬 수 있다.After the liquid removal process is finished, supply the silk noodle to the drying room and irradiate microwaves (2) 2.47GHz microwaves with a microwave generator to evaporate and dry the flame retardant liquid from the inside of the noodle. In this drying process, the flame retardant solution acts as an adhesive when it is dried. Therefore, it is preferable to separate the feed belt 6 from the supply belt 6 before drying to prevent adhesion between the shoulder and the belt. In the microwave frequency band, a frequency band of 2.47 GHz, which is known to be most suitable for vibration of water molecules used for moisture drying, was used. The preheated air that has passed through the installation section of the microwave is blown through the air blowing device and the air cushioning device to blow water vapor remaining in the inside of the inside of the surface during drying. The drying efficiency can be increased by inhaling the water vapor evaporated from the surface and flowing out. The belt is removed from the adhered foreign matter while passing through the cleaning unit installed on the lower conveyor. In the present invention, the drying process may be repeated three or more times to completely dry the plush.

상기 건조공정을 통과한 견면은 온도가 150∼250℃인 세라믹 히터(7)가 상하로 설치된 발포용 콘베이어 벨트를 통과하면서 발포되는데, 이때 견면의 내부(표면에서 45mm깊이)까지 가열되어 발포됨으로써 높은 강도와 낮은 흡수율을 가진 폴리에스테르 난연심재가 완성된다.The plush passed through the drying process is foamed while the ceramic heater 7 having a temperature of 150 to 250 ° C. is passed through the foam conveyor belt installed up and down. In this case, the inside of the plush (45 mm deep from the surface) is heated and foamed. Polyester flame retardant core with strength and low water absorption is completed.

본 발명에서는 상기 a)∼d)공정중 어느 한공정 이상에 대하여 2회이상 반복실시하여 난연제액의 침투 및 건조, 발포작용의 효과를 향상시킬 수 있다.In the present invention, it is possible to improve the effects of the penetration, drying and foaming of the flame retardant solution by repeating two or more times for any one or more of the above steps a) to d).

이하 다음의 실시예에서는 본 발명인 조립식 패널 구조체용 폴리에스테르 난연심재의 제조방법의 비한정적인 예시를 하고 있다.In the following examples, non-limiting examples of the method for producing a polyester flame retardant core material for a prefabricated panel structure according to the present invention are given.
