Description

technical field [0001] The invention relates to a method for manufacturing dual-function glass, in particular to a functional foam glass with dual functions of radiation protection and heat preservation and a preparation method thereof. Background technique [0002] With the continuous development of national defense scientific research, radiation medicine and nuclear technology applications, various radioactive rays are widely used, and the damage of rays to the human body and the damage to the environment is gradually recognized by humans. The research on radiation-proof materials has become a material research an important direction. However, with the further development of radiation devices and nuclear technology applications in recent years, traditional, single shielding materials can no longer meet the protection requirements such as mobile reactors and portable radiation sources, such as large concrete volume and poor mobility; preparation quality New anti-radiation ...
