Prefab 건축물에 적용 가능한 난연제 연구

A Study on Flame Retardant Applicable to Prefab Building

Fire suppression is almost impossible if the flame continues until the sandwich panels fire. A fire in a sandwich panel can cause flames and toxic gases, most of which can lead to serious property damage and personal injury. Therefore, in this study, sandwich panels are vulnerable to fire, and their fire resistance is lessened, making them the most vulnerable materials with EPS, especially vulnerable to flame. Therefore, a study was conducted to improve the performance. In the present study, the mixing design of flame retardants was finally assigned to three or four formulations, the use of which contained beta-sodium borosilicate relative to 100% of the solution, and the addition of a weight of 0.4 to 0.8 Respectively. Sandwich panels are a typical construction material among flammable materials and are limited to flammable materials, not standard panels of fire resistance performance. Therefore, a manufacturing method that can be judged as safe at the same level as glass fiber has been studied. To this end, glass-wool used in composite panels was used in the same test method, and flame spreading on the molten surface was also focused on fire resistance performance. In the evaluation of the sandwich panel through the development of the final flame retardant, cracks and other flames were not generated without melting in all the panel parts satisfying the fire resistance performance. This is because the flame retardant material is completely melted when the beads inserted into the sandwich panel are coated and the flame is penetrated.
