Problems solved by technology

Existing anti-radiation glass generally includes high-lead optical glass and organic anti-radiation glass, etc. However, this type of anti-radiation glass generally achieves its anti-radiation performance by adding metal elements such as lead, and lead, as a heavy metal, will pollute the environment and harm people. The health of the people makes this kind of radiation-proof glass have great potential safety hazards; and the radiation shielding range of this kind of radiation-proof glass is relatively limited, resulting in poor radiation protection effect.

Description

technical field [0001] The invention relates to the field of glass, in particular to a radiation-proof glass and a preparation method of the radiation-proof glass. Background technique [0002] Because radiation-proof glass has a large absorption capacity for high-energy radiation, it can be used as a shielding and peeping window material and is widely used in nuclear industry or medical fields. Existing anti-radiation glass generally includes high-lead optical glass and organic anti-radiation glass, etc. However, this type of anti-radiation glass generally achieves its anti-radiation performance by adding metal elements such as lead, and lead, as a heavy metal, will pollute the environment and harm people. The health of the people makes this kind of radiation-proof glass a great safety hazard; and the radiation shielding range of this kind of radiation-proof glass is relatively limited, resulting in poor radiation protection effect.
