Abstract

The invention provides a self-adhered type anti-neutron composite shielding material as well as a preparation method and application thereof. The shielding material is prepared from the following raw materials in parts by weight through radiation pre-crosslinking treatment: 100 parts of a rubber susbtrate, 5-50 parts of a tackifying agent polymer, 10-100 parts of a reinforcing agent, 20-200 parts of an anti-neutron additive, 0-50 parts of a softening agent, 0.5-10 parts of a vulcanizing agent, 0.5-5.0 parts of a vulcanization promoter, 0.5-10 parts of a vulcanization activator and 0-5.0 parts of an anti-aging agent. The invention further provides a preparation method of the shielding material and application of the shielding material in complex equipment or irregular parts. The self-adhered type anti-neutron composite shielding material provided by the invention has certain initial crosslinking degrees and self adhesion properties, is good in shape flow property, can be cured by self after being shaped, and has appropriate mechanical strength.

Description

technical field

[0001] The invention relates to a self-adhesive anti-neutron composite shielding material, a preparation method and application thereof, and belongs to the technical field of shielding materials. Background technique

[0002] With the continuous promotion and application of non-power nuclear technology in various fields in my country, neutron technology has been widely used in many fields such as material science, nuclear technology, and medicine. At the same time, the damage caused by radiation to the human body and the damage to the environment have gradually been recognized by human beings. In order to prevent or reduce the harm of radiation rays to human beings, radiation protection is required during the application of radiation, and radiation protection mainly depends on the performance of radiation shielding materials and the optimal design of radiation shielding structures. However, with the development of the application field of radiation technolog...
