A protection airtight door for underground civil air defense engineering and a preparation method thereof
The invention relates to underground engineering protection equipment, specifically to a protection airtight door for underground civil air defense engineering. The protection airtight door comprises a door frame and a door body, which are made of glass reinforced plastic material. A reinforcing fiber of the glass reinforced plastic material comprises 70%-85% of glass reinforced plastic fibers, 8-20% of neutron shielding fibers and 6-15% of X-ray and gamma-ray shielding fibers. Further, the door body is made by adding a lead boron polyethylene plate between two layers of the glass reinforced plastic material. The protection airtight door has the advantages of light self-weight, high strength, flexible opening and closing and good nuclear radiation shielding effect; with the glass fiber and radiation shielding fiber composite fiber, the glass reinforced plastic has a nuclear radiation shielding effect; the lead boron polyethylene plate is added between two layers of the glass reinforced plastic material, so that the shield ratio of the protection door to nuclear radiation reaches more than 97%.
