preparation example Construction

[0047] The invention also provides a method for preparing a liquid metal flexible shielding material, comprising: melting and coating the liquid metal on the surface of the substrate layer to form a liquid metal layer, and plating an anti-aging layer on the surface of the liquid metal layer by OSP technology.

[0048] In a preferred embodiment, the thickness of the liquid metal flexible shielding material is preferably 0.01-5 mm.

[0049] Wherein, forming the liquid metal layer by melting and coating the liquid metal on the surface of the substrate layer specifically includes:

[0050] Apply an adhesive layer on the surface of the substrate layer, melt and coat the liquid metal on the substrate to form a substrate containing the liquid metal layer, then use a pressure roller to combine the adhesive layer with the substrate containing the liquid metal layer, and remove the lining You get what you pay for.

[0051] Wherein, the material of the adhesive layer is preferably a the...

Abstract

The invention provides a liquid metal flexible shielding material and a preparation method thereof. The liquid metal flexible shielding material includes a substrate layer, a liquid metal layer and ananti-aging layer which are sequentially arranged from bottom to top. The liquid metal flexible shielding material has an excellent shielding performance and a thin thickness, is nontoxic, has a far better yield limit than traditional lead-containing particle radiation shielding materials, can achieve extremely excellent stretchable radiation shielding materials, and has excellent values in the fields of flexible shielding gloves, shielding clothes and even X-ray lithography.

Description

technical field [0001] The invention relates to the fields of medical treatment, military industry and industrial protection, in particular to a liquid metal flexible shielding material for shielding against X, gamma rays and neutron radiation and a preparation method thereof. Background technique [0002] With the wide application of nuclear energy and radiation technology in the fields of national defense, military industry, medical treatment, industry, and nuclear power, it has brought a lot of convenience to our lives, but it has also brought about increasingly serious radiation hazards. Among them, α particles, β particles, and protons of high-speed charged particles, neutrons of uncharged particles, and ionizing radiation of X-rays and γ-rays have short wavelengths, high frequencies, and high energy, which can cause acute and chronic radiation damage to the body. Accepting a certain dose of radiation in a short period of time can cause acute damage to the body, which i...
