Recently, high-power electronic devices are widely used, fire accident has occurred mostly due to electrical short circuit. Also, during the general fire, wire fire occurs as a secondary fire, the speed of the fire is doubled. So, wire upon the occurrence of fire accident, has been called to the cause of the spread in a large fire. In order to prevent major accidents, in some studies, investigate the strengthening wire coating’s heat resistance. Yet, wire coating that can withstand the 2 hours required until the fire suppression has not been developed. Therefore, in this experiment, an attempt to develop a coating to withstand more than two hours. The expanded graphite is a material contained in the fabric coated with some type of adhesive, and again coated with fire retardant nanomaterials, which can withstand long fire to develop expanded graphite. |
