Abstract

The invention provides a preparation method of X and gamma ray protection aramid paper. The method comprises the steps that an X and gamma ray shield agent nano powder is modified through a silane coupling agent and hyperbranched polymer and then added in an aramid solution; due to the fact that aramid and amino end group hyperbranched polymer are good in interface effect, the volume of addition of function powder in the prepared aramid paper is increased, the prepared aramid paper not only has the good strength and high-temperature resistant property, but also has the advantages of being highin X and gamma ray shield rate, good in durability, free of lead and light in weight, and a good application prospect in the X and gamma ray radiation protection aspect is achieved.

Description

technical field [0001] The present application relates to the field of radiation protection, in particular to a preparation method of X and gamma ray protective aramid paper. 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 were developed and pro...
