Abstract

The invention provides a radiation-proof shielding material for civil air defense facilities. The radiation-proof shielding material comprises a bottom plate and a top plate, the bottom plate is provided with a circle of first clamping groove, the top plate is provided with a circle of second clamping groove, the first clamping groove and the second clamping groove are formed correspondingly, anda plurality of refractory bricks are fixed between the first clamping groove and the second clamping groove in overlapped and bonded modes through cement; inner fixing layers, first shielding plate layers, second shielding plate layers and outer protecting layers are sequentially arranged on the outer sides of the refractory bricks from inside to outside; the bottom plate, the top plate and the outer protecting layers are formed by aluminum plates in a pressed mode; and the inner fixing layers are formed by lead plates in a pressed mode. The radiation-proof shielding material is used for manufacturing a door body of a shielding door, and is good in strength, good in radiation-proof performance and good in fireproof performance.

Description

technical field [0001] The invention relates to a shielding material, in particular to a radiation-proof shielding material for civil defense facilities. Background technique [0002] Radiation shielding doors are a basic element of civil air defense facilities. In order to ensure the airtightness of the radiation shielding door, the radiation source is prevented from radiating outward from the gap between the door panel and the door frame, causing harm to the personnel outside the shielding door. Therefore, it is generally necessary to install multiple sets of locking systems on the screen door, but each set of locking systems cannot be linked and needs to be locked separately. Therefore, in the event of an emergency, the staff needs to open the screen door to escape in an emergency. Due to the complexity of its switch, it is necessary to open multiple locking systems separately, which will inevitably lead to untimely response to the situation. [0003] Patent 20172088154...
