HEAT EXPANDIBLE FIREPROOF COMPOSITE AND MANUFACTURING METHOD OF REFRACTORY MATERIAL USING THE SAME AND FIREPROOF STRUCTURE PANEL USING THE FIREPROOF COMPOSITE AND INSTALL METHOD OF THIS

摘要

The present invention relates to a heat-expandable fireproof composition, a method for manufacturing a fireproof composition using the same, a fireproof structure panel using a fireproof composition, and a method for installing the same. According to the present invention, the fireproof composition is used for blocking the fireproof structure panel from flames, which results in improvement in high-temperature resistance, reinforcement of a thermally vulnerable part, simplified installation of the fireproof structure panel, and safe maintenance of a fireproof performance. The heat-expandable fireproof composition includes: a solvent including 15 wt% to 40 wt% of polyethylene glycol (PEG); a plasticizer including Tris(1-chloro-2-proply)phosphate (TCPP); an additive including 5 wt% to 10 wt% of organic diamine; a flame retardant including 5 wt% to 20 wt% of aluminum oxide, 20 wt% to 30 wt% of ammonium-based flame retardant, and 5 wt% to 30 wt% of expanded graphite; and an auxiliary agent including 2 wt% to 10 wt% of silica (SiO_2). The sum of the solvent and the plasticizer is 30 wt% to 60 wt%.
