FRP Fire Retardant FRP Panel Composition and Maintenance Methods of Concrete Structure Using Thereof

LEE PYOUNG WOEN

The present invention provides a fire retardant FRP panel composition. According to the present invention, the fire retardant FRP panel composition includes: 100 parts by weight of an epoxy resin; 1-5 parts by weight of calcium sulfoaluminate; 5-20 parts by weight of fiber; 3-20 parts by weight of a retardant; 0.1-10 parts by weight of a fire retardant supplement agent; 10-40 parts by weight of a hardener; 5-30 parts by weight of a lightweight material; 10-40 parts by weight of nano-ceramic particles; 2-10 parts by weight of polyvinyl alcohol; 0.1-10 parts by weight of re-emulsification polymer powder; 1-10 parts by weight of a low shrinking agent; 1-10 parts by weight of an adhesion enhancer; 0.1-20 parts by weight of a defoamer; and 0.1-20 parts by weight of a dispersing agent. According to the present invention, the fire retardant FRP panel composition has improved fire retardant performance, mechanical performance, durability, impact resistance, rigidity, and aseismicity. Therefore, the fire retardant FRP panel composition is effective in preventing fires and has good formability and aseismicity. In addition, the fire retardant FRP panel composition has a simple production process and low production costs.
