Abstract

The invention provides a preparation method of a non-woven fabric for X and gamma ray protection. The method comprises the steps of preparing interlayer water-containing graphene oxide; preparing first graphene oxide powder intercalated with bismuth tungstate according to the interlayer water-containing graphene oxide; preparing second graphene oxide powder intercalated with europium oxide, samarium oxide, gadolinium oxide and barium oxide according to the first graphene oxide powder; preparing X-ray radiation protection function lead-free powder according to the first graphene oxide powder and the second graphene oxide powder; preparing the non-woven fabric for the X and gamma ray protection according to the X-ray radiation protection function lead-free powder. The addition amount of functional powder in the prepared PE / PP sheath-core composite fiber is improved, the fiber has good physical and mechanical properties, textile processing properties and wearability and also has high X and gamma ray shielding rate, good durability, no lead and light weight, and the application prospects in X and gamma ray radiation protection are good.

Description

technical field [0001] The present application relates to the field of radiation protection, in particular to a preparation method of a non-woven fabric for protection against X and gamma rays. Background technique [0002] In recent years, with the rapid development of national defense scientific research, radiation medicine and atomic energy industry, the use of various rays has become increasingly widespread. X and gamma rays are important ones. Long-term exposure to X and gamma rays can cause damage to gonads, mammary glands, hematopoietic bone marrow, etc. Excessive doses can even cause cancer, posing a serious threat to the human body. Therefore, according to the properties of X and γ-rays and their mechanism of action with substances, corresponding materials should be selected and prepared for protection. [0003] Metal materials such as lead plates and iron plates were first used for X and gamma ray shielding. Later, leaded glass, plexiglass and rubber products wer...
