  The present invention relates to a fire protection panel and a method for manufacturing the same, and more particularly, to a fire protection panel suitable for application to a wooden fire door and the like, and a method for manufacturing the same.

For accommodations such as hotels and apartments of a certain size or more that require consideration in terms of fire prevention and evacuation regulations, and buildings for use as apartments, fire doors that have the ability to block out flames for a predetermined time (for example, 740 ° C. for 20 minutes) are required. is set up.
Fire doors installed in these buildings usually require a wide variety of performances such as sound insulation, security, wind pressure resistance, and earthquake resistance in addition to the ability to block flames for a predetermined time. For this reason, such a fire door has a complicated structure, increases the weight of the door, and has a high manufacturing cost.

  In order to reduce the weight of the entire fire door, Patent Document 1 proposes a fire door in which a frame is formed of an integrally formed member of an organic material and an inorganic material. In the fire prevention door described in Patent Document 1, a heat insulating core material is loaded in a hollow portion of a frame, and a refractory plate is stuck on both sides thereof, and the frame is an integrally formed member of an organic material and an inorganic material. The fire door is assembled with the inorganic material directed toward the outer peripheral surface of the frame.
