Abstract
The invention discloses an anti-radiation plate and a preparation method thereof. The anti-radiation plate is prepared from 80 to 120 parts of ultrahigh molecular weight polyethylene and 6 to 10 parts of boron carbide by sufficient stirring, filling into a die cavity, high-temperature sintering, maintaining of temperature and pressure and cooling modeling. According to the invention, boron carbide is added into ultrahigh molecular weight polyethylene, so the prepared plate is capable of defending radiation by a plurality of rays; and thus, investment cost for protection is reduced.
