METHOD FOR MANUFACTURING ENVIRONMENTALLY FRIENDLY LIGHTWEIGHT FIRE RETARDANT INSULATION MATERIAL FOR FIRE PREVENTION USING CERAMIC FIBER AND WATER GLASS AND ENVIRONMENTALLY FRIENDLY LIGHTWEIGHT FIRE RETARDANT INSULATION MATERIAL

摘要

An environmentally friendly lightweight fire retardant insulation material using a ceramic fiber and water glass, according to the present invention, is an insulation material, which is obtained by the following steps: mixing 80 to 120 vol% of water glass with 100 vol% of the ceramic fiber to be deposited; drying the deposited mixture at the temperature of 70-80C for 48-72 hours; and foaming the mixture at the temperature of 200 to 250C for 3 to 5 minutes by irradiating the dried mixture with microwave. Accordingly, the present invention provides the fire retardant insulation material which has improved heat insulation performance for fire prevention and fire retardant performance compared to conventional insulation materials, and which is environmentally friendly, lightweight, and economically-improved extraordinarily.;COPYRIGHT KIPO 2017
