Abstract

The invention provides a quick dry type neutron-shielding lacquer putty and a method for preparing the same. The quick dry type neutron-shielding lacquer putty is used for filling a hole or an aperture of a neutron radiant point shielding structure in order to reduce the leakage of neutron radiation and improve the whole protective performance of a shielding system. The material is prepared by adopting a coagulant, a neutron moderator, a neutron absorber, a colorant, water and other compositions mixed together. The quick dry type neutron-shielding lacquer putty has good neutron-shielding performance, short drying time, simple structure, convenient construction, strong practicability and good economical benefit.

Description

technical field [0001] The invention relates to a neutron-proof quick-drying putty and a preparation method thereof, which are used for shielding protection of various neutron radiation sources such as isotope neutron sources, nuclear reactors, and electron accelerators. Background technique [0002] Isotopic neutron sources, nuclear reactors and accelerators will produce nuclear radiation during operation, especially neutron radiation has a strong penetrating ability, which poses a huge threat to the health of operators. Nowadays, iron, lead, polyethylene, paraffin or composite shielding materials are generally used to shield these radiation sources. During the installation and use of these materials, a small gap will be left at the material connection, and neutron radiation will pass through these gaps. It will damage the operator and greatly reduce the protective effect of the overall shielding structure. Secondly, there are many pipes and holes around the radiation sour...
