摘要

依據CNS 11227之防火門標準，在925℃燃燒1小時，門背面溫度未超過260℃為A級門。近年開發之無機聚合物材料具有耐高溫、強度高、不具毒性、熱膨脹係數小、不易腐蝕、對環境無害、節能等特性，前期實驗研究已充分証實其效果。然而無機聚合物耐高溫的性能雖佳，但其自重甚大，若作為防火門填充材則宜適當輕量化。本研究則嘗試以增加孔隙之方式達到減低重量，同時亦可增加防火耐火效能。
增加孔隙最直接的方式即使用發泡劑。傳統發泡劑大致分為兩類，水性發泡劑及鋁粉。本研究以發泡劑種類、掺入比例為實驗參數，製作厚度(4cm)之試體餅。試驗時正面以1000 ℃之火焰噴燒，再量測試體餅背面選定各點溫度以測試耐火性能。實驗結果顯示使用5%水性發泡劑之無機聚合物，其重量可減少12%，其中厚度為4cm之試體當以火焰噴燒1小時，背面中心點溫度約241度，已可達到我國A級防火門之標準需求。

According to the national standard for fire resistant doors, CNS 11227, after burning under 925 ℃ for one hour, the temperature behind the door does not exceed 260 ℃, it is a Class A door. A recent developed material, namely geopolymer, is known to have the properties of heat resistance, high strength, non-toxic, lower thermal expansion coefficient, and difficult to corrode. It is also nearly no harm to the environment, and energy-saving. However, the performance of heat resistance of geopolymer is excellent, but its weight is quite heavy. if appropriate lightweight fill material should be as fire doors. The present study is attempts to increase the porosity in order to reduce its weight as well as the fire insulation.
The most direct way to increase porosity is the use of foaming agents. Traditional foaming agents are roughly divided into two categories; water-based and aluminum powder. In this study, the types of foaming agent, and the incorporation ratios were taken as the experimental parameters to make the specimen with 4cm thickness. During the experiment, the front side of the specimen was sprayed with flame at 1000 ° C, the temperature in the back of the specimen was measured in at least an hour duration. The results revealed that while used 5% water-based foaming agent, the weight of specimen reduced up to 12%, the temperature behind the specimen was only about 241 ℃. It has achieved the national standard for Class A fire resistant doors.
