Problems solved by technology

However, since the long-term use temperature of polyethylene is around 80°C, this greatly limits the scope of use of this type of shielding composite material.
In recent years, the research on high temperature resistant shielding materials has also been increasing, but there is no material that comprehensively considers the neutron and γ-ray shielding, flame retardancy and thermal expansion properties of the material during use.

Abstract

The invention provides a high-temperature-resistant neutron and Upsilon-ray shielding composite and a preparation method thereof. The high-temperature-resistant neutron and Upsilon-ray shielding composite is made from, by weight, 20-200 parts of a base material, 100-800 parts of an anti-radiation functional aid, 5-100 parts of a fiber reinforced material, 50-150 parts of a flame-retardant functional filling material, and 1-10 parts of a processing aid. The high-temperature-resistant neutron and Upsilon-ray shielding composite prepared herein has good neutron and Upsilon-ray shielding performance and good flame retardance, may operate normally in the temperature range of 150-260 DEG C, has excellent resistance to high temperature, and has low average linear expansion coefficient; it is indicated that the material has good size stability, and stability of neutron and Upsilon-ray shielding performance can be guaranteed; the high-temperature-resistant neutron and Upsilon-ray shielding composite is suitable for use as a radiation-protective material in a high-temperature environment.

Description

technical field [0001] The invention relates to a high temperature resistant neutron and gamma ray shielding composite material and a preparation method thereof, and relates to the technical field of nuclear radiation shielding protection. Background technique [0002] In recent years, nuclear energy and ionizing radiation technology have achieved rapid development in radiation processing, nuclear medicine, nuclear industry and other fields, which has greatly promoted the progress of human society. However, while nuclear technology has brought great benefits to people, the harm caused by various ionizing radiations to the environment has gradually been recognized by people. On the one hand, countries around the world have formulated corresponding laws and regulations to effectively control and standardize the safe use of ionizing radiation; on the other hand, the development of stable, safe and efficient radiation shielding materials to protect the health and safety of pract...
