Abstract

The invention discloses a preparation method of a light anti-radiation interlayer of an explosion door and used slurry liquid, and the slurry liquid for manufacturing the light anti-radiation interlayer of the explosion door is prepared by mixing modified inorganic expansion material powder, a lead compound, a solvent A, dicalcium phosphate and hydroxy propyl distarch phosphate, the mass ratio of the modified inorganic expansion material powder to the lead compound to the solvent A is (10-20): 1: (5-10); the mass ratio of the lead compound to the dicalcium phosphate to the hydroxy propyl distarch phosphate is (40-80): (20-40): 1. The density of the light anti-radiation interlayer prepared from the slurry liquid is far smaller than that of a lead plate interlayer used by a traditional anti-radiation door, and the light anti-radiation interlayer has excellent anti-radiation capacity, meets the strength requirement and can effectively resist shock wave pressure generated by explosion.

Description

technical field [0001] The invention belongs to the technical field of civil air defense engineering safety, and in particular relates to a preparation method of a radiation-proof interlayer used for an explosion-proof door. Background technique [0002] Blast-proof door is a kind of anti-blast protection equipment that can resist the explosion shock under certain conditions, dissipate the shock wave pressure generated by the explosion, absorb the impact kinetic energy of fragments, prevent penetration, and effectively prevent the explosion hazard from continuing to be affected by the blast wave. Explosion-proof doors are widely used in command rooms, civil air defense projects, explosives warehouses, inflammable warehouses, workshops, mines and other places. Especially the explosion-proof doors used in civil air defense projects can effectively resist and stop the shock waves and fragments generated by the explosion, and protect people's lives and property.
