Embodiment 1

[0030] A shielding protective door, including a door frame and a door body, the door frame and the door body are made of glass fiber reinforced plastic material, the glass fiber reinforced plastic material includes 85% fiberglass fiber, 9% anti-neutron fiber and 6% anti-X, γ ray fiber;

[0031] A ring of protruding rubber rings is provided on the outer side of the door body to fit and seal with the door frame.

Embodiment 2

[0033] The object of the present invention is to provide a shielding protective door and a preparation method thereof.

[0034] The technical scheme of the present invention to achieve the above objectives is as follows: a shielding protective door device, including a door frame and a door body, the door body of the protective door is made of two layers of glass fiber reinforced plastic composite lead-boron polyethylene board, the glass fiber reinforced plastic The material composition is 80% fiberglass, 12% anti-neutron fiber and 8% anti-X, gamma ray fiber.

[0035] Further, the thickness of the lead-boron polyethylene plate is 20mm;

[0036] The preparation method of the composite lead-boron polyethylene plate in the middle of the two layers of glass fiber reinforced plastics is as follows:

[0037] The first step is to prepare reinforcing fibers: use fiberglass fiber as warp, anti-neutron fiber and anti-X, γ-ray fiber as weft to blend into a flat fabric;

[0038] The seco...

Abstract

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.

Description

technical field [0001] The invention relates to a shielding protective door. Background technique [0002] The protective door is set on the outermost side of the entrance and exit, which has two functions of blocking shock waves and isolating poisonous agents. The protective door should be able to block the shock wave and meet the corresponding resistance requirements. When selecting, it should not only meet the needs of the hole size, but also meet the design pressure requirements. The patent with the publication number CN102182387A discloses a protective door with a composite steel structure, which has properties such as light weight and high resistance to the door body. Although the price of the steel structure door is relatively high, and the anti-early nuclear radiation performance is also poor, but because of its light weight and flexible opening and closing, it is usually used for relatively large vehicle entrances and exits. [0003] The airtight door is located ...
