Yellow tungsten oxide is mainly used as a radiation protection filler to prepare a radiation-resistant composite. Such an anti-radiation material is mainly prepared by 60-68 parts by weight of anti-radiation filler and 32-40 parts by weight of matrix. Wherein, the anti-radiation filler includes the following three components mixed in any ratio: yellow tungsten oxide, antimony oxide, single rare earth oxide and/or its salts; the substrate is selected from polyvinyl chloride or EPDM.

This is an environmentally friendly radiation-resistant composite. Because this kind of radiation protection material is relatively environmentally friendly from the choice of materials and processing methods - using rubber or polyvinyl chloride as raw materials, using lead-free radiation protection fillers, and adopting melt processing methods that do not require vulcanization. The performance of the prepared anti-radiation composite material containing yellow tungsten oxide is the same as or better than the anti-radiation lead rubber prepared by existing vulcanization process.
