Screen protection door device and preparation thereof
The invention discloses a screen protection door device which comprises a door frame and a door body. A lead boron polyethylene plate is compounded between two glass fiber reinforced plastics to form the glass the protection door body, and the glass fiber reinforced plastics are made of 80-85% of glass fiber reinforced plastic fibers, 5-15% of neutron shielding fibers and 3-10% of X and gamma ray shielding fibers. The screen protection door device is light in dead weight, flexible to open and close, high in shock wave resistance and fine in nuclear radiation shielding effect. By the aid of composite fibers of glass fibers and radiation shielding fibers, the glass fiber reinforced plastics have nuclear radiation shielding effects, and the nuclear radiation shielding rate of a protection door can reach more than 97% as the lead boron polyethylene plate is compounded between the two glass fiber reinforced plastics.
