Abstract

The invention discloses a synthetic design of a polymetallic composite compound capable of meeting the requirements for radiation protection of X-ray in different energy sections, and a rubber-based composite shielding material of the polymetallic composite compound. The polymetallic composite compound has a completely novel structure obtained by high-temperature calcination of a polymetallic oxalate complex and comprises four metals, wherein two rare earth metals are included. The polymetallic composite compound provided by the invention reduces the contents of an oxygen element or non-metallic elements in the rubber-based composite shielding material, is reduced in usage amount in the process of rubber processing, can achieve a better shielding effect in a limited amount of a filling material in parts under processing conditions, can realize directional design synthesis according to needs, and effectively enhances overall shielding efficiency of an anti-radiation material.

Description

technical field [0001] The invention belongs to the field of X-ray radiation protection materials, and specifically relates to the synthesis design of a class of multi-metal composite compounds and rubber-based composite shielding materials that can meet the radiation protection requirements of different energy segments of X-rays. Background technique [0002] X-ray shielding is mainly the absorption of radiation energy by shielding materials. The absorption of ray energy by matter depends on the interaction between matter and ray. The photoelectric absorption ability of the shielding material is mainly determined by the K-layer absorption edge of the shielding material. When the K-layer absorption edge of the shielding material can cover the X-ray energy, good shielding performance will be achieved. The K-layer absorption edges of different elements are different, and the range of energy absorption for rays is also very different. Therefore, a combination of multiple elem...
