Document Type and Number:
WIPO Patent Application WO/2020/149566
Kind Code:
A1
Abstract:
Disclosed is a method for manufacturing a lead-free radiation shielding sheet. The method for manufacturing a lead-free radiation shielding sheet according to the present invention comprises a coating film lamination step of repeating a process of sequentially: applying, to one side of a base material for forming a radiation shielding sheet, a radiation shielding material containing radiation shielding powder and a binder for forming a film that are mixed together; laminating same; drying same; and integrating same, so as to form a multi-layered radiation shielding coating film on the one side of the base substrate. According to the present invention, lead, which is heavy and harmful to the human body and the environment, is not used, and thus side effects such as diseases and environmental pollution caused by lead do not occur; it is possible to lighten the weight of the radiation shielding sheet and manufacture protective clothing having excellent wearability; and flexibility can be improved compared to that of a lead rubber sheet, and thus handling and storage are convenient. In addition, the lead-free radiation shielding sheet manufactured by the present invention can be applied to clothing having various designs and radiation protection means for various uses due to flexibility and ease of manipulation.
