Problems solved by technology

[0002] Glass is a transparent semi-solid and semi-liquid substance, which forms a continuous network structure when it is melted, and is a non-metallic silicate material whose viscosity gradually increases during cooling and does not crystallize. The main component of ordinary glass is silicon dioxide. It has high chemical stability, thermal stability and good transparency, so it is widely used in various fields, while the existing glass has no radiation protection effect and cannot be used in places with high radiation, such as: nuclear power plants, hospital etc.
The price of radiation-proof glass itself is particularly high, and a single-layer radiation-proof layer cannot play a good radiation-proof effect, and the existing radiation-proof glass has darker color, insufficient brightness, and low refractive index, so it needs to be improved.

Abstract

The invention discloses special radiation-proof glass for a nuclear power station, which comprises a base layer, obtuse angles are arranged around the base layer, a first radiation-proof layer is wrapped on the base layer, a support layer is arranged on the first radiation-proof layer, a buffer strip is arranged on the support layer, and the buffer strip and the support layer are integrally poured. A second anti-radiation layer matched with the supporting layer is arranged on the supporting layer, a pressure-resistant layer is arranged on the second anti-radiation layer, a protective layer wraps the outer side of the pressure-resistant layer, fixing holes are formed in the periphery of the protective layer and extend to the pressure-resistant layer, and connecting rods matched with the fixing holes are fixed to the fixing holes. The fixing holes and the connecting rods are filled with adhesives, the connecting rods are fixed to the protective cover, and the protective cover wraps the four corners of the periphery of the protective layer. The composite material is stable in structure, is formed through multi-layer pouring, has a good bonding effect, improves the overall compression resistance, effectively improves the radiation resistance, heat resistance and insulation effect, prolongs the service life, and is simple in preparation process and easy to obtain.
